Vacuum pump manufacturer

Shanghai EVP is a professional vacuum pump manufacturer. If you don't understand the vacuum pump selection, please contact Xiaobian to find out how to choose the vacuum pump:

First, the vacuum volume should be calculated first: check the time required to reach the required vacuum, the flow resistance and leakage of the vacuum piping. Consider the pumping rate required to maintain the vacuum under certain process requirements after achieving the required vacuum.

Second, the type of gas to be pumped and the amount of pumping: check and determine the type of pumping and pumping capacity required by the process. Because if the type of gas being pumped reacts with the liquid in the pump, the vacuum pump system will be contaminated. At the same time, consideration must be given to determining the appropriate exhaust time and the amount of gas produced during the pumping process.liquid ring vacuum pumps manufacturer

Third, determine the working range of the vacuum pump: First, we must check to determine the vacuum degree required for each process. Because each process has its own range of vacuum, it must be carefully studied and determined; determine the ultimate vacuum, check the ultimate vacuum of the vacuum pump system based on the vacuum required to determine the process, because the ultimate vacuum of the system is determined The optimal working vacuum of the system. In general, the system's ultimate vacuum is 20% lower than the system's operating vacuum and 50% lower than the foreline's ultimate vacuum.Dry vacuum pump

Fourth, the general vacuum pump selection requirements :

1. Vacuum degree, vacuum volume, main medium, temperature, and main volume equipment;
2. Vacuum flows into the medium and flow, pressure, temperature, and law;
3. Pumping capacity, extraction of gaseous medium, temperature;
4. The area of ​​the vacuum equipment, the degree of automation, and the specifications of the vacuum piping.
