Product Description

Water Ring Type Vacuum Pumps (2BE3)
Liquid Ring Vacuum Pump

Greentech International (Xihu (West Lake) Dis.) Co., Ltd is the professional vacuum pump supplier.
The application range and characteristics:
2BE3 series water ring vacuum pumps and compressors are designed and manufactured by our company integrating with the advanced technology abroad. They are not only can save energy, but also can work constantly for a long time.
Under the rough vacuum situation, the requirements for the liquid ring vacuum pumps are very rigorous. So the 2BE3 series products are designed for pumping various gases. They are widely used in many industries, such as, the paper, mine, power station, chemical etc.

2BE3 series products can be driven with many different sets, such as, the V-belt, synchronal motor, gear box etc. In order to save space, more than 2 or at most 4 sets of the 2BE3 series pumps can be driven by 1 motor simultaneously.
When set a middle wall in the casing, the pressure tolerance between the 2 sides is lower than 80kPa and the 2 parts can work in different vacuum status respectively. Thus 1 pump can work well like two. Hereby the product operating flexibility is improved effectively.
The main characteristics of 2BE3 series products:

· The tolerance, corrosive status, and the begrime situation can be easily observed by the big inspection port on both sides of the end-shield.
· The 2BE3 series pumps have flanges both on the top and sides with the same diameter. It is more convenient to connect with the 2BE3 series pumps.
· The bearings are all used of the imported products in order to keep the precise orientation and the high stability during the working of the pump.

· The material of the impeller is QT400 nodular iron or steel plates for ensuring the stability of the pump under the various rigorous situations and extending the life of the pump effectively.
· The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE3 series pumps.
· The shaft bushing is made of stainless steel plates to extend the life of the pumps 5 times more than the normal material.

· The V-belt pulley (when the pump is driven by the belt) is used of the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
· The unique design of setting the separator above the pump saves the space and decreases the noise efficiently.
· All the spare parts are cast by the resin sands that make the surface of the pump very smooth. So it is not necessary to cover the surface of the pump with putty and gives out the heat efficiently.
· The mechanical seals (optional) are all used the imported products so as to avoid the leakage during the working of the pump for a long time.

Vacuum Pump

What Are Vacuum Pumps?

Vacuum pumps use air flow as the source of energy. The system is ideal for dewatering wet media, creating filter cakes, and pneumatically moving materials through a pipe. A vacuum pump works through air flow that is moved by differential pressure. The pump’s air flow develops a vacuum in a chamber that is called the vacuum box. As the air flow collects gas at a faster rate than atmospheric pressure, it is considered the “heart” of a vacuum system.

Principles of operation

Vacuum pumps work by reducing the volume of air that moves through them. Depending on the design, there are several different types of vacuum pumps. All of these types operate under the same principles, but have their own special features. Here are some of their most important characteristics. In addition to their capacity, the main differences between these pumps are their manufacturing tolerances, materials of construction, and level of tolerance for chemicals, oil vapor, and vibration.
Vacuum pumps create a partial or low-pressure vacuum by forcing gas molecules from their high-pressure states to their low-pressure states. However, these pumps can only achieve a partial vacuum, and other methods are necessary to reach a higher level of vacuum. As with all pumps, there are several ways to increase the level of a vacuum.
First, consider the type of vacuum you want. This is the most important factor when choosing a vacuum pump. If you need a high level of vacuum, you’ll need a high-quality vacuum pump. High-quality vacuum pumps have a high pressure limit, while ultrahigh-quality pumps are capable of achieving a very low vacuum. As the pressure decreases, the amount of molecules per cubic centimeter decreases and the quality of the vacuum increases.
Positive displacement pumps are best suited for low and medium-pressure systems. But they can’t reach high vacuum, which is why most high-pressure systems use two pumps in tandem. In this case, the positive displacement pump would stall and the other one would be used instead. Similarly, entrapment pumps have higher-pressure limits, so they must be refreshed frequently or exhaust frequently when there is too much gas to capture.
Another important aspect of vacuum pump operation is its speed. The speed of pumping is proportional to the differential pressure across the system. Therefore, the faster the pumping speed, the lower the draining time.

Design

A vacuum pump is a mechanical device used to generate a vacuum. It can create a low or high vacuum. These pumps are used in the process of oil regeneration and re-refining. The design of a vacuum pump must be compatible with the vacuum. The pump’s mass and speed should be matched.
The design of a vacuum pump is important for many reasons. It should be easy to use and maintain. Vacuum pumps need to be protected from external contamination. For this reason, the oil must be kept clean at all times. Contamination may damage the oil, resulting in pump failure. The pump’s design should include features that will prevent this from happening.
The main objective of a vacuum pump is to remove air and other gases from a chamber. As the pressure of the chamber drops, the amount of molecules that can be removed becomes more difficult. Because of this, industrial and research vacuum systems typically require pumps to operate over a large pressure range. The range is generally between one and 10-6 Torr. A standard vacuum system uses multiple pumps, each covering a portion of the pressure range. These pumps can also be operated in a series to achieve optimal performance.
The design of a vacuum pump can vary depending on the application and the pressure requirement. It should be sized appropriately to ensure that it works properly. There are several different types of pumps, so selecting the right pump is essential to maximizing its efficiency. For example, a slow running vee belt drive rotary vane vacuum pump will have a lower running temperature than a fast-running direct-drive pump.
Vacuum Pump

Performance

The performance of a vacuum pump is an important indicator of its overall condition. It helps determine whether the system is performing optimally and how high the ultimate vacuum level can be achieved. A performance log should be maintained to document variations in pump operating hours and voltage as well as the temperature of the pump’s cooling water and oil. The log should also record any problems with the pump.
There are several ways to increase the performance of a vacuum pump. For example, one way is to decrease the temperature of the working fluid. If the temperature of the fluid is too high, it will lead to a low vacuum. A high temperature will make the vacuum degree of the pump even lower, so heat transfer is an important part of the process.
Nozzles are another major component that impacts the performance of a vacuum pump. Damage or clogging can result in a compromised pumping capacity. These problems can occur due to a number of causes, including excessive noise, leakage, and misassembled parts. Nozzles can also become clogged due to rusting, corrosion, or excess water.
Performance of vacuum pump technology is vital for many industries. It is an integral part of many central production processes. However, it comes with certain expenses, including machines, installations, energy, and maintenance. This makes it essential to understand what to look for when purchasing a vacuum pump. It is important to understand the factors that can influence these factors, as they affect the efficiency of a vacuum pump.
Another important factor in determining the performance of a vacuum pump is throughput. Throughput is a measurement of how many molecules can be pumped per unit of time at a constant temperature. Moreover, throughput can also be used to evaluate volume leak rates and pressure at the vacuum side. In this way, the efficiency of a vacuum pump can be judged by the speed and throughput of its leaks.

Atmospheric pressure

Vacuum pumps work by sucking liquids or air into a container. The amount of vacuum a pump can create is measured in pressure units called atms (atmospheric pressure). The pressure of a vacuum pump is equal to the difference between atmospheric pressure and the pressure in the system.
The amount of force produced by air molecules on each other is proportional to the number of impacts. Therefore, the greater the impact, the higher the pressure. In addition, all molecules have the same amount of energy at any temperature. This holds true for both pure and mixture gases. However, lighter molecules will move faster than heavier ones. Nevertheless, the transfer of energy is the same for both.
The difference between atmospheric and gauge pressure is not always straightforward. Some applications use one term to describe the other. While the two concepts are closely related, there are key differences. In most cases, atmospheric pressure is a higher number than gauge pressure. As a result, it can be confusing when choosing a vacuum pump.
One method is to use a U-tube manometer, a compact device that measures the difference between atmospheric pressure and vacuum. This device is commonly used for monitoring vacuum systems. It can measure both negative and positive pressure. In addition, it uses an electronic version of a gauge.
The atmospheric pressure affects the performance of a vacuum pump. When working with porous materials, the pump must overcome leakage. As a result, it must be equipped with enough capacity to compensate for variations in the porosity of the work piece. This is why it is critical to buy a vacuum pump that has a large enough capacity to handle the variation.

b. Rotary vane pumps are used in a variety of vacuum applications. They are suitable for industrial applications, freeze drying and cabinet making. They use oil as a sealant and coolant, allowing them to perform well in a variety of applications. This makes them ideal for use in a variety of industries.
The pumping rate of the vacuum pump is important. This refers to the volume pumped from a given point at a given rate. The higher the speed, the faster the pump will expel the air. Depending on the gas composition, this number will vary. When choosing a vacuum pump, gas composition and process requirements should be considered.
Vacuum pumps are used in a variety of industries from laboratories to medical facilities. In medical applications, they are used in radiation therapy and radiopharmaceuticals. They are also used in mass spectrometers, which are instruments used to analyze solid, liquid, or surface materials. Vacuum pumps are also used in decorative vacuum coatings and Formula 1 engine components. A trash compactor is another example of using a vacuum pump.
