How to Ensure Proper Maintenance of Your Slurry Pumps? (In Only 6 Steps)

 

STEP #1: Check the belts

 

• When should you check the belt tension of the slurry pumps?

If your slurry pumps are belt driven please check the tension once quarterly at a minimum. Belts that are too tight will cause damage to the light series motor bearing and once that bearing fails then the thrust bearing will start to fail in the pump. Belts ran too loose will cause poor performance and slippage causing damage to the sheaves.

 

 

• How to tell if the belts are loose on slurry pumps?

An experienced ear can tell if the belts are too loose. They will be making a flapping sound. Belts that are too tight could cause the motor to be pulling high amps or bearing temperatures to increase before you start to notice bearing failure.

 

STEP #2: Check the oil

 

• When should you change the oil of your pump?

If your pump is on oil lubrication please check periodically to make sure no water or product is present in the oil. If your sealing device is ok, changing the oil on a regular interval will increase the lifetime of any pump.

 

• Water is bad for your slurry pump: how to know if there is water in the oil?

Water is bad as it will cause bearing and/or motor failure. Seals do leak by nature and a small amount of water is ok. A significant amount of water in the oil will cause the oil to be milky.

Some key features may be already incorporated into your pump's design to help identify water in your oil. One such feature is the moisture sensor which will trip when there is excessive amounts of water in the oil. Water in the oil is an early indicator that sealing has been compromised.

The first place to check is the sealing device used on your particular pump.

Another thing to check is the setting distance from the end of the probe from the housing.

 

STEP #3: Check your impeller clearance

 

Best performance is achieved by checking your impeller clearance on occasion. Consult your manual for proper clearance. When checking clearance look for excessive wear in the impeller and other wetted parts.

Wear in the wetted parts can cause the clearance to increase causing a loss in performance.

Wear can be caused by the abrasiveness of the product being pumped or by running the pump off the designed curve for the pump.

 

STEP #4: How to review slurry pump requirements

 

Is the slurry pump still being asked to do what it was built to do?

Sometimes systems and processes change but we continue to ask the same of our equipment without taking into consideration the changes to the process that may have been made throughout the years.

For trouble shooting it is a good idea to install a pressure gauge and flow meter on the discharge line of the pump. You can take the pressure reading and multiply it by 2.31 to give you a rough TDH. You can then take the TDH and a flow reading and see if your pump is running near BEP on the pump curve. If not, please contact the OEM.

 

 

STEP #5: Monitor your pumps temperature

 

Temperature sensors are provided with our submersible pumps for protection of the motor. Each manual provided with the pump will outline how to hook up and monitor the temperature sensors for maximum lifetime.

 

• Why should you care?

If the motor gets too hot the sensors will trip and the pump will shut down until the motor cools. If the sensors are not connected you are running the risk of burning up your motor.

If you ask for a warranty claim and these devices are not connected then your warranty is void.

 

• When should you check your slurry pump temperature?

Our horizontal and cantilever pumps need to have the temperature of the bearings checked weekly while the pump is in operation. Using a temperature gun check the bearing housing temp in the closest proximity to the bearing.

 

• What temperature should the slurry pump be?

While most pump bearings run in the 140 to 170 F range I suggest never allowing temperatures to exceed 200 degrees F maximum. Bearing temperatures can be a sign of too much lubrication or beginning stages of bearing failure.

 

STEP #6: Monitor the pump bearings

 

Using some form of vibration equipment. This will give you an indication if bearings start to fail.

Vibration analysis should be performed by a qualified and trained engineer/ technician experienced with this type of work.

Proper vibration monitoring will give the user a lot of useful information which can increase the MTBF and improve performance of the pump.

Use of Foil, Parchment, Wax Paper and Freezer Paper

 Use of Foil, Parchment, Wax Paper and Freezer Paper

You may know that foil is silver, freezer paper, parchment paper and wax paper are paper, but does that's all you know about them? These four kitchen staples have a variety of uses and can make cooking much easier. Here are the differences and tips on how to use them.

Wax paper vs. parchment paper

Food grade wax paper and parchment paper are both coated papers. The difference is in their coating. Parchment paper - available in bleached and unbleached - is coated with silicone, while wax paper is coated with, you guessed it, wax. Soy or paraffin wax, to be exact.

Their coatings give them different uses. Parchment paper's silicone coating makes it heat-resistant and non-stick. Use this paper wonder to line your baking sheet with food that won't stick to it.

The best use for wax paper is to line countertops and tables before spreading out pie crusts or kneading bread to prevent staining. Wax paper can also be used to wrap food for freezing or even lining pans to make things like fudge. Placing a sheet of wax paper between items to be frozen can also prevent them from sticking together.

So, in summary, parchment paper is good for hot applications and wax paper is good for cold applications.

Wax paper vs. freezer paper

Because they are so similar, both freezer paper and wax paper are used to wrap and freeze food. The biggest difference is that freezer paper is coated with plastic on one side only, while wax paper is coated with wax on both sides. Because of the plastic coating, freezer paper is usually more durable than wax and protects better in the freezer. 

For example, meat wrapped in wax paper will only stay in the freezer for a few months without burning. On the other hand, meat wrapped in freezer paper can be kept for up to a year. This is because freezer paper is more resistant to moisture.

If you plan to cook food soon, you can use wax paper, but use freezer paper for long-term freezer storage.

Wax paper vs. foil

Okay, so foil and wax paper have many similar uses, but which is better? A good rule of thumb is to use wax paper if you don't want it to stick, and foil if you want to insulate.

Unlike wax paper, aluminum foil can also be reused or recycled. So, if you want to save the planet and you can't choose between foil and wax paper, choose foil. Be sure to rinse it well before sliding it into the recycling bin.

Non-stick silicone steam paper

Foil vs. parchment paper

Foil is basically very thin aluminum. Many people use it to arrange cooking dishes for easy cleanup, which is a great trick, but unlike parchment paper, foil does not have non-stick properties. You might put a small piece of foil on the bottom of a baked potato or cookie.

In addition, research in the International Journal of Electrochemical Sciences found that small amounts of aluminum may leach into food during the cooking process. Just like wax paper, the best choice is parchment paper if there is heat involved.

Common cooking staples have very different uses. Make sure you use the correct one in this guide. We have food grade wax wrappers, beeswax rolls, and vegetarian wraps for sale, designed to make your kitchen and restaurant convenient while doing our best to protect the environment. Contact us to buy now!

Why replace the coil spring?

 The function of the Auto Suspension Coil Spring is to support the vehicle at the desired height, maintain the proper positioning angle and absorb road shocks transmitted through the tires and shock absorbers.

Constant flexing in normal service can gradually weaken the suspension system, allowing the car to sag. Once this sag becomes apparent, the entire car suffers. The steering components are forced out of position, thereby changing the geometry of the steering linkage. The loss of the original coil spring can only be fully recovered by installing a new coil spring. This will return the vehicle to the correct height.

Most steering linkages systems are designed so that the tie rod assemblies connect to the center link or rack at some angle. On these vehicles, with the steering linkage in front of the spindle, a sagging suspension will force the tie rod out-ward and cause a “toe out” condition.f the linkage is positioned behind the spindle on these vehicles, the outward force of the tie rods caused by the drop in suspension height will cause a “toe-in” condition.

The steering arm connection for vehicles equipped with rack and pinion steering have the same design characteristics and functions incorporated in parallelogram steering. Thus a change in vehicle height will have the same effect on toe change with either linkage system.

There are some linkage systems that are designed with all components approximately horizontal. A decrease in suspension height will cause these changes to be reversed, pulling the tie rods inward and produce the “toe-out” condition in

Incorrect ride height can also affect camber. As the vehicle begins to sag, the angle of the control arm changes. This change in suspension geometry and camber will greatly affect lateral wear or in-and-out motion of the tire as it rolls over irregular surfaces. Suspension systems are designed to minimize tire movement in and out; however, extreme lateral wear caused by geometry changes can lead to premature tire wear

A sagging suspension means that tires wear faster, some steering control and handling is lost, headlight aim is adversely affected, and vehicle appearance is marred.

COIL SPRING INSPECTION

A quick overall visual inspection will detect any obvious sag from front to rear or from side to side. Upon visual inspection under the car, look for the two ends of the control arms out of level, damaged or worn rubber bumpers and shiny or worn spring coils. All indicate weak coil springs.

Before visual inspection or suspension height measurements can be accomplished, the vehicle must be on a level surface, tires must be full and there should be no passenger or luggage compartment load. Beginning at the rear bumper, jounce the car up and down several times, proceed to the front bumper and repeat, releasing during same cycle as rear jounce.

More accurate inspection will reveal less obvious side-to-side sag by measuring heights at specific points on each side of the suspension system. If bumper is bent or damaged, compare ground-to-fender measurements taken at center of wheel cutout in fender. Allowable height difference should be no more than for ground-to-bumper measurement.

For accurate front-to-rear comparison, measurement points should be checked against manufacturer’s recommendations for the specific model, after determining that the vehicle is properly unloaded of abnormal cargo.

If inspection reveals a weak Coil Springs For Suspension Parts on either side, both sides must be replaced. Never attempt to avoid replacement by hiding the effect of a weak spring with any kind of insert, block or so called stabilizer. An insert will raise the vehicle height, but at the expense of handling and comfort. An insert virtually disables the coil it separates, and eliminates its ability to absorb shock. Further, the insert concentrates the stresses on a single point of the coil rather than distributing these forces throughout the spring. This simply accelerates fatigue and failure of the spring. Overload and air shocks are equally unsuitable as a means for overcoming sagging coil springs. These devices are designed to maintain proper vehicle height in overloaded conditions only.

Benefits of Using Body Lotions

You should never neglect your body care and we recommend using a body lotion.

 

Many women tend to follow a multi-step facial skincare routine, however, the opposite is true for our bodies, which we often neglect - this leads to problems such as dryness, cellulite and even wrinkles, and we should pay more attention to body care.

 

 

Body Lotion

Why and how does dry skin happen?

There are a range of reasons why your skin may be prone to dryness.

 

• In the winter. Your skin is especially prone to dryness in the winter months. The cooler months - and the cold air and wind that come with them - can dry out your skin. In addition, enjoying hot showers and/or heaters can also cause dry skin. That's because they remove moisture from your skin, making it dry and saggy.

 

• In the summer. It's not just the cold that can dry out your skin. Summer often brings some unwanted dryness too! High temperatures, UV rays and frequent showers can dry out your skin. Dehydrating your skin.

 

• Lifestyle factors. Stress and certain dietary habits, such as eating too much salt, can affect your skin's moisture levels.

 

• Medication problems. In some cases, specific medications can cause moisture levels to drop. You think this may be the case, it is recommended to consult your doctor.

  

Body Lotion

Treat your skin gently

Although skin conditions may be caused by internal factors, there are some regular treatments or products that we can incorporate into our daily lives to improve its condition. Limit your bath time. Unlike facial skin, body skin tends to be thinner and the skin on our bodies varies in different areas. Hot water and long showers or baths can remove oil from the skin and strong soaps need to be avoided. Strong soaps and detergents can strip the oil from the skin.

 

In the fall and winter months, you can mix a few drops of essential oil into your body lotion or focus on dry areas first and then use body lotion to enhance micronization. Depending on your situation, you may choose to add different essential oils such as rose to moisturize, lavender to help with anti-inflammation and relaxation, and the fresh scent of grapefruit to relieve stress and help tone the skin. Instead of just pouring the lotion on and smoothing it out, gently massage it in an up-and-down rubbing or circular motion to relax the skin and muscles, which also facilitates absorption.

Benefits of body care

It helps to slow down the aging process. Body lotion will help soothe the body during the dry winter months when we lose moisture, and it will better help keep our skin glowing during the summer months when frequent showers drain away the oils. Once you establish a body care routine, it is easier to maintain. It boosts confidence and when you look good, you feel good. It keeps the skin healthy, which in turn makes you healthier.

 

There are many styles of body lotions available today, and there are also relatively light silicone ingredients available if you want to combine the feel of your skin with the moisturizing effect.

 

Health & Beyond can also custom body lotions. Our body lotions are nourishing, moisturizing and come in a variety of scents including fresh citrus, sweet florals and more to replace perfume in everyday life and make skincare routines less of a stress. With a package weight of 236ml, the smaller size makes it easier to carry around for travel. It is moisturizing, nourishing, non-sticky and smells good.

The Difference Between Gel And Liquid Hand Sanitizers

 When people think of hand sanitizer, they usually think of the standard gel they see in the doctor's office, the teacher's classroom, or the neighborhood grocery shop. It's what they often see in public places and therefore what they are most familiar with.

 

But gel isn't the only form. There are liquids, foams, wipes, and sprays, and each has its own unique advantages and disadvantages when it comes to PPE equipment. The two most common types of hand sanitizer are gels and liquids, but how do they differ? Is there a situation or application where one is preferable to the other?

 

Gel hand sanitizers vs liquid hand sanitizers

A gel hand sanitizer is a hand sanitizer with a thicker, almost jelly-like consistency - hence the name gel. Liquid hand sanitizers, on the other hand, are much closer to the consistency of water. Due to the alcohol content and the unique production methods of the manufacturing companies, you may find some bubbles in both antibacterial mixtures. Depending on the additives, both sanitizers can be clear or almost any colour in the rainbow. Blue, yellow, purple, and so on.

 Gel Hand Sanitizer

 

In terms of set-up, you can usually find both hand sanitizers in busy healthcare settings such as clinics, as both are easily transferred from wall-mounted dispensers. This is a huge benefit for doctors, patients and visitors alike. The average consumer often prefers the gel form as it is easier to dispense without spilling everywhere. This makes it the preferred choice for protection on the go, or even when you are relaxing at home.

What do gel and liquid hand sanitizers have in common?

When it comes to the effectiveness of gel or liquid hand sanitizers, they are on almost equal footing. It really boils down to the right application. According to the CDC, you need to apply the entire surface of your hand correctly and then rub the product into your skin and nails until your hands are completely dry. This usually takes about 20 to 30 seconds.

 

In addition, the alcohol content of the sanitizer is something you should be aware of.

 

A good hand sanitizer should contain alcohol.

It is important to note this because there are many brands that market alcohol-free sanitisers. Your sanitiser will only be effective against germs if it contains at least 60% alcohol. You can find both gel and liquid sanitizers that meet this requirement.

  FDA Approved Hand Sanitizer

 

The difference between gel and liquid hand sanitizers

As several studies on hand sanitizers have established, there are some significant differences between the gel and liquid forms. Gels tend to take about 30 seconds before bacteria and viruses are completely eliminated, while liquids usually take about half that time. However, this delayed action of the gel gives you enough time to completely cover your hands in the sanitizer so that the product can be used to its full potential.

 

Liquids have a low viscosity and are therefore very fluid. Studies have shown that gels are often preferred over liquid disinfectants as they are usually less smelly and more portable, among other benefits. Therefore, the fact that there are more gel hand sanitizers than liquids makes sense.

 

In the end, the differences between gel and liquid hand sanitizers really don't affect their superpower to fight germs. If you wish to decide between the two, consider the reason you need the product and when you plan to use it. That way, you can weigh up the pros and cons of either type and choose the one that suits you best.

 

At Health & Beyond, we understand that many different situations and needs may arise throughout your day. That's why we offer a wide range of hand sanitizer options. Whether you need more information, samples, or a quote, we would be delighted to talk to you. For more details, contact us now.

Five Tips for FRP Grating Selection

HEBEI DONGDING produces more than 100 different FRP grating series to meet a variety of customer needs. The following advice will help select the most appropriate grating series for an application.

 

 

1. Determine Design Criteria

Find FRP grating design criteria in the project specifications under Section 06 74 13 “Fiberglass Reinforced Gratings”. If unavailable, refer to ASCE 7-16, Table 4.3-1 for minimum live loads. Allowable deflection for FRP grating is usually limited to ¼" (6 mm) for pedestrian comfort. Larger deflections may be permissible for heavy, temporary loads. Deflection greater than ½" (12 mm) is not advisable due to prying action on hold down clips and potential loosening of fasteners. Long panels utilizing multispan conditions reduce panel deflection.Compare design loads to the grating Safe Load and you will find high Factors of Safety. Serviceability (not strength) generally controls FRP design.

 

2. Choose Appearance

A variety of bearing bar colors, surface grit and topcoat treatments are available for FRP grating. Yellow and light gray are standard bar colors. Fine grit is suitable for bare feet; standard medium grit for industrial uses; or coarse grit, if lubricants or debris collection are expected. A urethane top coat adds greater UV protection or custom colors.

 

3. Identify Constraints

Bearing bar height and/or spacing may determine grating series selection. Issues such as existing supports, ADA compliance, high heels, dropped objects, drainage, sunlight penetration, ventilation, and even vehicular traffic could be a requirement for a particular installation. With all these situations to consider, DURAGRID® I6000-1", I6000-1.5" and T5000-2" remain the most
common pultruded series selected. DURAGRATE® 1.5" thick x 1.5" square mesh is the most common molded grating series.

 

4. Select Resin

Generally, polyester is suitable for most conditions;vinyl ester for harsh chemical exposure and additional corrosion protection; phenolic where fire / smoke /toxicity are of primary concern.
Most Dongding load tables are based upon polyester resin (PE) since vinyl ester (VE) resin has only slightly greater mechanical properties. Phenolic grating does have unique properties and separate load tables.

 

5. Maximize Span

With your initial grating selection chosen, review load tables to determine the maximum span to meet load(s) and allowable deflection. Compare this to plan dimensions and determine support configuration. Selecting a taller bar allows longer grating spans and reduces the frequency of beams. This increases the load on each support beam, but fewer slightly larger beams is often more economical than additional smaller beams. If the beam spacing is considerably more/less than the maximum span, review load tables to see if other grating meets the design criteria.

 

Conclusion

With many geometric, material, assembly, and finishing options, FRP grating is able to meet the needs of nearly any application. Contact a member of our team today with any questions about our FRP solutions.

The Benefits of Wearing A Wetsuit

Everyone knows they keep you warm, but the benefits of wearing a wetsuit go far beyond temperature. When you think of wetsuits, the first thing that comes to mind is probably the need to stay warm while swimming in cold water. After all, that's why they were invented. The average wetsuit is designed to keep you warm while submerged in water that can range from 50 to 70 degrees, depending on the style and thickness. But in reality, wetsuits have many other benefits that are easily overlooked.

 

Benefits of Wearing a Wetsuit for Inner Peace

One of the benefits of wetsuits is that they can actually relieve stress and help you perform better. Knowing that your body will remain at a very comfortable temperature allows you to focus more on your actual performance rather than how you feel during that performance. Emphasizing physical comfort and temperature can make it harder to feel excited about the activity you are about to perform. Wetsuits can solve this problem, especially if you find the perfect wetsuit for you.

 

In addition, by understanding all the other benefits of a wetsuit besides keeping you warm, you will feel safer every time you jump into the water. This is why you see people swimming in wetsuits when the water is not yet cold. So, what are the benefits of these wetsuits?

 

Buoyancy

A huge benefit of wearing a wetsuit is that it makes it easier for you to float. The natural buoyancy of neoprene allows you to sit higher in the water than you would without a wetsuit. This means less drag and easier swimming. This applies mostly to triathletes looking for any competitive edge to save time. This is why you often see swimmers wearing wetsuits in warm water. Their wetsuit helps athletes save extra energy during the swim portion of the race that they can expel during the rest of the race.

 

Speed

Another benefit of wetsuits comes from the outer coating or "skin" that is used to cover the outside of the wetsuit. They are used to repel water, which means you can actually swim faster and glide through the water more easily. The outer coating is called "Super Composite Skin" or SCS, and this technological advancement really extends the limits of the capabilities of today's wetsuits. Some scientists say that SCS on wetsuits can reduce drag in the water by about 15 percent. Some professional swimmers also claim that the right wetsuit can reduce time by 5% to 10%, depending on the distance swum. *Please note that this type of skin is only found in triathlon or open water swimming specific wetsuits, not general water sports wetsuits.

 

Confidence

Knowing that you have the extra buoyancy and speed to help is one of the great benefits of a wetsuit. But now, these benefits offer you the added benefit of confidence. Having a great fitting wetsuit that keeps you warm and helps you swim easier and faster can help you push yourself as an athlete and possibly do some swimming outside of your comfort zone. These are the things that athletes need to get better at, and if a wetsuit can provide that, then I recommend taking full advantage of it.

 

Compression

A wetsuit works by holding a thin layer of water tightly between your skin and the wetsuit. Your body heat heats the water to 98 degrees and then it keeps you warm. The tighter the suit, the warmer it is. But another benefit of a wetsuit is that when it's very tight, it automatically compresses your muscles and joints, which also allows you to perform better and last longer. A wetsuit feels like running with compression sleeves over your knees. With a wetsuit on, your entire body will feel tighter and ready to perform. The benefits of this wetsuit will also help you work harder as a swimmer or surfer, which will ultimately allow you to perform better in this sport.

Global Shutter VS Rolling Shutter

Are you wondering how to choose between Rolling shutter and Global shutter for your application? Then, read this article to better understand the differences between rolling shutter and global shutter and how to choose the one that perfectly fits your application

Today's industrial cameras and imaging systems have sensors that capture and record images for various processing and analysis purposes. These sensors use an electronic shutter to capture images. An electronic shutter is a device that controls the exposure of photon wells on the sensor. It also determines whether the pixels are exposed line by line or as a complete matrix. The two main types of electronic shutter are Rolling shutter and Global shutter. This article explores shutter mechanisms, the difference between the two shutters, and where to use them.

 

Rolling shutter

---

What is Rolling shutter?

Rolling shutter mode in a camera exposes the pixel rows one after the other, with a temporal offset from one row to the next. At first, the top row of the image starts collecting the light and finishes it. Then the next row starts collecting light. This causes delay in the ending and starting time of light collection for consecutive rows. The total light collection time for each row is exactly the same.

 

The difference in imaging between rolling shutter sensor and global shutter sensor is predominantly reflected in dynamic image acquisition. When fast-moving objects are captured by a rolling shutter sensor, the rolling shutter Effect occurs. In rolling shutter, all pixels of the array in the image sensor are not exposed simultaneously and each row of sensor pixels is scanned sequentially. Due to this, if an object moves faster than the exposure time and readout time of the image sensor, the image gets distorted owing to rolling light exposure. This is called rolling shutter effect.

 

Global Shutter

---

What is Global Shutter?

Global shutter mode in an image sensor allows all the sensor's pixels to start exposing and stop exposing simultaneously for the programmed exposure period during every image acquisition. After the end of the exposure time, pixel data readout begins and proceeds row by row until all pixel data has been read. This produces non-distorted images without wobble or skewing. Global shutter sensors are typically used to capture high-speed moving objects.

 

How does a global shutter sensor work?

A global shutter exposes all lines of an image at the same time, 'freezing' the moving object in place. This prevents distortions, which makes global shutter technology the ideal choice for applications with moving objects and rapid movement sequences, including automatic license plate detection as part of traffic monitoring, for example.

 

The advantages of global shutter sensors:

1. High frame rates

2. High resolution

3. Crystal-clear images, even for very short exposures

4. Outstanding noise characteristics, even in poor lighting conditions

5. Broad dynamic range

6. High quantum efficiency of up to 70%

 

Where we need a global shutter camera and rolling shutter camera?

A global shutter camera is mainly used for capturing high-speed moving objects without artifacts and motion blur. Global shutter cameras are used in applications such as ball tracking, industrial automation, warehouse robots, drones etc.

Rolling shutter sensors offer excellent sensitivity for imaging and can be used for cost effective applications. It is predominantly used for capturing slow-moving objects such as agriculture tractors, slow speed conveyors, and standalone applications like kiosks, barcode scanners, etc.
