Liquid ring vacuum pumps manufacturers

Liquid ring vacuum pump can be widely applied in the vacuum pump, etc., and use more stable, but in the use of equipment may arise suddenly stop running, if rule out conditions is a sudden power outage, so we need to check whether the equipment problems, this is not to the secondary to open, we should deal with the problem and then began to run, let’s learn about the equipment suddenly shut down how to solve it.

1. the packing or seal wear, resulting in air leakage into the equipment, then need to check the packing or seal and according to the needs of the corresponding replacement, but also check whether the lubrication is normal.

2. Check whether the inlet pipeline is leaking. It is usually necessary to check the inlet line for air cavitation or air leakage.

3. Sometimes the impeller or pipeline may be blocked. It is necessary to check whether the pipeline is blocked by obstacles and the liquid ring vacuum pump. If there is any blockage, it should be dealt with in time. If there is no blockage of the liquid ring vacuum pump, it needs to be dealt with again.

4. The immersion depth of the bottom valve or inlet pipe of the equipment is still not enough, so it needs to be immersed to the correct depth to continue normal operation.

Liquid ring vacuum pump factory is located in pudong new area, Shanghai, China. EVP vacuum equipment co., ltd. welcomes you to visit and guide. Since the establishment, adhere to the “integrity-based, customer first” purpose, in line with the “quality-based, excellence” philosophy of business and sales, strive to provide customers with services, but also make the enterprise has made considerable development. We are looking forward to working with new and old customers to create brilliant future.

Liquid ring vacuum pump we sometimes hear that liquid ring vacuum pump and liquid ring compressors, though called a vacuum pump, called a liquid ring compressor, but in fact both principle and using effect are the same, but if a sheep anywhere, why to two name, let’s take a look at the difference between them.

1. Different shaft power

The same specifications of the liquid ring pump, the actual power of the liquid ring compressor is larger than the vacuum pump, and the impeller circumference speed is generally selected according to the requirements of the vacuum pump, so, as the liquid ring compressor, then in the low efficiency of the operation, the required shaft power will be greater. Because, the liquid ring compressor with the power is often larger than the vacuum pump.

2. Different compression ratios

The so-called compression ratio, is the higher efficiency of the compression ratio. In general, the vacuum pump compression ratio is higher than the liquid ring compressor.

3. impeller circumference speed range is different

The peripheral velocity of the impeller mainly depends on the pressure difference between the suction chamber and the compression chamber. Because the suction pressure of the liquid ring compressor is often atmospheric pressure, but the vacuum pump exhaust pressure is generally atmospheric pressure, so the pressure difference of the liquid ring compressor is large, so its required circular speed is also large. Therefore, it can be seen that the same specification of the liquid ring pump, the use of vacuum pump and liquid ring compressor performance is different, if the liquid ring vacuum pump as a liquid ring compressor, then only increase the speed accordingly, so as to lower the cost of operation.

Liquid ring vacuum pump manufacturer of liquid ring vacuum pump is only applied to water at the beginning, but as people to exploit and use it, its application field is becoming more and more popular, and can be used in vacuum coating, vacuum filter, vacuum evaporation and so on, with the continuous development of vacuum technology, the use of the equipment also gradually get the attention of people, among them, its use in the vacuum coating has very much, let’s come to detailed knowledge of its application.

1. First, in optics, a piece of optical glass or quartz coated with one or more thin films of different substances can become either highly reflective or non-reflective (i.e., anti-reflection film) or any expected ratio of reflection or transmission data, and can also be used as a filter for absorption of one wavelength and transmission of another wavelength.

2. Anti-reflection film is widely used in photography and a variety of laser start, to the new building of large Windows coated glass, the demand is very much.

3. Vacuum coating occupies a very important position in electronics. A wide range of inherited circuits. Including the memory, the calculator, the notification logic element and so on must use the conductive film, the insulation film and the maintenance film.

4. Chromium film is used as the mask for preparing the circuit. Magnetic tape, magnetic disk, semiconductor lasers, Josephson devices, charge-coupled devices (CCD) are also available in a variety of thin films for use in liquid-ring vacuum pumps.

5. In terms of development devices, the video head, high-density video tape, transparent conductive film installed for plane development, photoconductive film of camera tube and aluminum lining of fluorescent screen of development tube are also prepared by vacuum coating method.
