In recent years, with the sustained and rapid economic development in our country, China's vacuum pump industry maintained its rapid growth momentum and achieved sustained and steady development. In its rapid development, vacuum pump companies and users are constantly exploring how to promote the efficient operation of the vacuum pump, which factors affect the efficiency of the vacuum pump what? After Xiaobian access to relevant information and analysis of the user in the process of using the vacuum pump common problems On the summary of the following aspects are the factors that affect the efficiency of the vacuum pump. Factors that affect the efficiency of the vacuum pump 1, the steam pressure Steam pressure is low and the pressure fluctuations have a greater impact on the ability of the vacuum pump, steam pressure should not be less than the required working pressure, but the design of the vacuum pump has been used stereotypes, too much increase Steam pressure does not increase the amount of suction and vacuum. In addition, to ensure that the pressure of steam supplied by the boiler is stable, it is advisable to use a boiler to provide working steam to the steam injection pump so that the steam pressure will not fluctuate to ensure the performance of the vacuum pump is stable. 2, circulating cooling water cooling water supply is insufficient, the condenser will heat, the sound of the air becomes larger, the degree of vacuum drops rapidly, and even the steam will return to the suction pipe. Condensate water plays a decisive role in multistage vacuum pumps. Condensed water can condense the steam abundantly, and the partial pressure of water vapor in the discharge pressure of the vacuum pump needs to be higher than the corresponding full steam pressure. Therefore, the condensate water temperature should be lower than The pressure of the full temperature, in order to ensure the normal operation of the pump. 3, the nozzle Nozzle is an important part of the performance of the vacuum pump, the problems are: nozzle installed wrong, installed crooked, blocked, damaged, corroded and leaked, no matter what precaution, nozzle clogging is inevitable. On the one hand, when the steam pipe is installed, the remaining iron filings and slag in the pipe will clog the nozzle; on the other hand, when the vacuum pump system is disabled, the steam pipe is prone to rust and the rust drops and blocks the nozzle when in use. 4, the use of the environment The impact of the environment mainly refers to the system was pumping gas pollution in the liquid steel process, the liquid steel will emit a lot of gas, but also there will be some small particles such as oxide powder skin was sucked into the vacuum pump, these Small particles will be piled on the pump body, reducing the exhaust pipe flow guide, to extend the exhaust time, reducing pump pumping function.
