How to avoid the problem of vacuum pump?

The most common use of Roots vacuum pump is sewage treatment. Roots vacuum pump manufacturers found that there will be some problems in the use of vacuum pumps of different brands. There are many reasons for the problem. What we need to do is how to avoid the problem of vacuum pump? After reading the following points, you will know how to deal with it! Methods to avoid roots vacuum pump failure Roots vacuum pump Start the pump Sudden liquid intrusion can damage the pump because of rapid cooling. The gas cannot reach the required temperature to evaporate the liquid. Additional steam cannot be pumped out in time because the front stage pump has been overloaded and the front stage pressure may rise to an excessively high level. To prevent this, it is necessary to install a receiver between the treatment room and the roots pump so that the liquid can be absorbed before entering the pump.

To prevent this, it is necessary to install a receiver between the treatment room and the roots pump so that the liquid can be absorbed before entering the pump. Dust accumulation In the process of generating particles or carrying dust - such as metallurgy or crystal drawing - it is necessary to install a dust filter at the air inlet of the pump to protect roots pump and downstream pump. The so-called debris protection net should be installed at the air inlet of roots pump. This prevents large solids and weld beads from being ejected from the welded joint due to improper cleaning when the system is used for the first time. In this case, it is recommended to use the accessories of the pump manufacturer, because the debris protection net is designed so that its free section can match the nominal diameter of the pump. This ensures that the pump speed will not be affected by unexpected conductivity loss. Extraction of critical gas When extracting valuable and high purity gases, such as helium 3 or helium 4, these gases must be avoided from contacting the surrounding air at all costs. At this time, the pump body is required to have high air tightness and low leakage rate in the area lower than 10-5 to 10-8 HPA L / s. Pfizer vacuum provides permanent magnet coupling for motor to replace ordinary shaft feed through parts. This makes the leakage on all shaft seal rings history. Enclosed motors can also be used. However, the operator must rely on the pump manufacturer for maintenance, because this kind of enclosed motor is specially developed for the pump. For magnetic coupling, cost-effective standard motors can be used. PUFA vacuum provides up to 250 m3 / H magnetic coupling for two-stage rotary vane vacuum pump and up to 12000 m3 / H magnetic coupling for Roots pump.
