What affects the performance of dry vacuum pump
With the development of dry vacuum pump, people continue to study how to improve the effective operation of dry vacuum pump. What are the reasons that affect the performance of dry vacuum pump?
The supply of cooling circulating water is insufficient, the cooler becomes hot, the cyclone sound becomes larger, the vacuum value drops rapidly, and the steam returns to the exhaust pipe. Condensate has a very important effect in multi-stage dry vacuum pump. Condensate can fully cool the steam. The partial pressure circuit of steam in the pressure discharged from dry vacuum pump must be higher than its corresponding steam pressure. Therefore, the temperature of condensate is its working pressure, and the influence point of natural environment is the environmental pollution of waste gas to the management system. In the whole process of desolvent treatment, a lot of waste gas will be released. In addition, some small particles such as air oxide powder are sucked into the dry vacuum pump. The small particles accumulate on the pump shell, which reduces the flow of the exhaust pipe, increases the vacuum time and reduces the vacuum effect of the pump.
The nozzle is an important part of the dry vacuum pump. The disadvantages are: installation reversal, installation deformation, blocking, damage, etching and leakage of the nozzle. No matter what preventive measures are adopted, the blockage of the nozzle is inevitable.
When installing the steam pipe, not only the residual iron pin and welding on the pipe will block the nozzle, but also if the screw vacuum pump system is out of service, the steam pipe is easy to rust, and the rust marks will fall down and block the nozzle. Low steam pressure and pressure fluctuation have great influence on the working capacity of dry vacuum pump, so the steam pressure can not be less than the specified pressure. However, the design of common dry vacuum pump has been decided on the whole. Even if the steam pressure is too high, it is easy to improve the gas supply and vacuum value. In order to ensure the stable steam pressure of boiler supply and demand balance, when using boiler experts to improve the steam in the steam jet pump, the steam pressure is not easy to produce fluctuations, so as to ensure the stable characteristics of dry vacuum pump.
With the rapid development of China's economy, China's dry vacuum pump manufacturing industry has also maintained a sustained growth trend and maintained a stable development. People must master the factors that affect the efficiency of dry vacuum pump and improve the efficiency.
