Why FOLLOWER PUMPS Succeeds
The follower plate is lowered slowly into the barrel. This is because if the pump is lowered too fast, air cavities will be created in the barrel.
This will cause waste of the material and process breakdowns. Especially with high viscosity fluids. It is very important to use a follower plate when using greases.
1. High Viscosity Fluids
Viscosity is the property of a liquid that describes its resistance to flow. The thicker a fluid is, the higher its viscosity, and the more energy it requires to make it flow. A high viscosity fluid flows very slowly compared to a low viscosity fluid, such as water.
Viscosity is measured in centistokes (cP). The centipoise value for a specific fluid can be obtained by pouring it into a glass or plastic tube and measuring how long it takes for a steel ball to fall through the orifice at the bottom of the tube.
Many manufacturers require a viscosity measurement before pumping, as viscous liquids often require a more powerful pump to force their way through the product. These viscosity-based decisions help manufacturers avoid high shear – which can damage particle structures and equipment – and preserve the integrity of the fluid.
The viscosity of a fluid can also be measured using an instrument called a viscometer. These instruments have a very narrow orifice and measure the distance between two markings on the surface of the fluid as it flows down the tray. They can be used with a variety of products, but are most commonly associated with shear-sensitive liquids such as paints, inks, and pastes that need to be consistent throughout the production process.
As a result, it is important to use the most accurate instrument available for each application. Ideally, the viscometer should be able to return a precise kinematic unit of viscosity in cP or centistokes that can be easily converted into traditional units such as pounds per gallon and gallons per minute.
The most common type of pump for viscous liquid is the piston pump. Piston pumps are powered by either pneumatic or hydraulic motors and can be used in a wide variety of applications. They are typically the most reliable and cost-effective pump types, but they do not have the capacity to deal with very high viscosity liquids without a follower plate. The follower plate is attached to the piston pump package and draws the fluid into the piston pump via gravity or air pressure.
2. Low Temperature
One of the most challenging operating conditions to pump in is a cold snap. Ice can form over time and if the equipment is not properly defrosted it can cause major damage to the equipment, especially when the ice is on components that are in contact with the liquid being pumped. The good news is that it only takes a little bit of preparation and a little know-how to keep the machine running in even the most extreme weather conditions.
A good starting point for a successful ice-free pumping season is a solid site plan. This is a must for any pumping operation, as it will ensure that all parties involved in the process are kept safe and that everyone is on the same page. To that end, a good pumping site plan should include details about the weather and what it means for pumping operations. This will help operators take the necessary precautions, such as putting down wet floors and using the right gloves when dealing with frozen water. In addition, it is a good idea to have a checklist of tasks that should be performed before the pumping equipment is turned on or turned off for the day.
3. High Viscosity Grease
When it comes to lubricating high-speed pumps, it’s vital to choose the right grease. Using the wrong grease can lead to unnecessary heat generation and bearing wear.
Choosing the correct grease will ensure your pump has a long life and runs at peak performance. The key is to find a grease that has been designed for high-speed operation and meets the speed, temperature, load and bearing requirements of your equipment.
One important factor that must be considered is the base oil viscosity. This is often specified on the product label. The base oil viscosity should be low enough to provide an adequate lubricating film while also not being too thick to create excessive heat and drag.
The NLGI grade of the base oil is also an important consideration. Having a higher NLGI number means that the grease has been specially formulated to work well at high speeds.
Another important factor to consider is the type of thickener used in the base oil. Depending on the thickener, a grease will have different channeling, bleed, dropping point and consistency characteristics.
A variety of thickeners are available, including lithium, calcium, polyurea and silica. ปั้มไลค์ can either be a powdered solid or a liquid.
While these can all be useful, there are some that are more versatile. Typically, these are short-fibered and have better channeling characteristics than those with longer fibers.
In addition, a variety of additives are also available that can help with certain lubrication needs. For example, anti-wear additives can reduce friction and extend bearing life.
The thickness of the lubricating film is critical for separating metal surfaces so that rolling elements aren’t forced to contact each other. A fluid film that’s too thin can result in mixed lubrication and boundary lubrication, which leads to wear and increased power loss.
Aside from the basic properties of the base oil and thickener, the Viscosity Index of the grease can also play an important role in determining how the oil reacts to changes in temperature. Generally speaking, an oil with a high VI will undergo little viscosity change in response to temperature fluctuations, while a low VI will experience large changes.
4. High Pressure
When a firefighter is faced with an intensely burning fire, their ability to quickly control their water supply becomes an essential tool. They know that they have a limited amount of time to fight the fire and want to make sure they’re delivering enough water to keep up with the demand.
One of the most effective ways to do this is to dispense a large quantity of high-pressured water in the shortest period of time possible. A FOLLOWER PUMP does this with the help of its inflatable follower plate and stable and automatic set air pressure.
This technology is not new, but it does require a little maintenance to keep it in tip-top shape. The best way to ensure you’re getting the most out of your pump is to inspect it on a regular basis.
First of all, you need to check the packing gland and adjust it if necessary. If the gland is too loose, it will not seal properly and will result in water leakage. If the gland is too tight, it may be too hot and damage the bearings.
Next, you need to check the cam follower. This is a small but important part on some 2.0 TFSI engines. Premature wear of the cam follower is known to lead to camshaft failure. A simple visual inspection should suffice, but it’s a good idea to replace this as needed (this is a genuine OE replacement from the VAG group).
The biggest challenge with a pump like this is to keep the water flowing. If the flow is too slow, you could run out of water and your crew would be stuck in a sticky situation.
