Molecular Vacuum Pump molecular vacuum pump is mainly the use of high-speed rotation of the rotor to transfer momentum to the gas molecules, the gas molecules to achieve directional movement speed, which is compressed, was driven to the exhaust port after a pre-evacuated Molecular vacuum pump traction molecular vacuum pump. Understanding such products, must be familiar with its relevant parameters, so that for the subsequent work will be of great assistance. Molecular vacuum pump Next, several of its main parameters are mainly described: 1, the maximum working pressure of molecular vacuum pump: molecular vacuum pump maximum working pressure unit is Pa, which refers to the maximum intake pressure corresponding to the inlet pressure. At this pressure, the pump can work continuously without deterioration or damage, thus achieving maximum operational efficiency. 2, compression ratio: compression ratio is the pump outlet pressure for a given gas inlet pressure ratio. 3, Ho coefficient: Pump pumping area on the actual pumping speed and molecular effusion calculated by the ratio of the theoretical pumping speed. 4, pumping speed coefficient: the actual pumping speed of the pump at the entrance of the molecule by the molecular effusion calculated theoretical pumping speed ratio. 5, the reflux rate: pump back flow rate unit is g / cm2.s. It refers to the pump when the required conditions work, through the pump inlet unit area pump flow mass flow rate. 6, the starting pressure of molecular vacuum pump: Molecular vacuum pump starting pressure unit Pa, it refers to the pump start without damage and the pressure of the pumping effect. 7, the pressure before the pump: molecular vacuum pump pressure unit before the stage is Pa, it refers to the exhaust pressure below one atmosphere of molecular vacuum pump outlet pressure. 8, the largest molecular vacuum pump before the pressure: the largest molecular vacuum pump unit before the pressure unit is Pa, which means more than the pump can damage the previous pressure. With the increasing demand of vacuum pumps in the market, the research and development of molecular vacuum pumps are imminent. Further research on their relevant parameters is necessary for the future development of molecular vacuum pumps, which deserves the attention of more professionals. I believe in the near future molecular vacuum pump will become the main force of the vacuum pump. Related Articles: Roots vacuum pump parameters trochoidal line vacuum pump parameters
