With the rapid development of China's industry, the application of vacuum pump is also more and more widely. For example, in the fields of plastic machinery, pesticide chemical industry, dye chemical industry, cryogenic equipment, pharmaceutical and chemical industry, food machinery, electronics industry and vacuum equipment. In order to better understand the vacuum pump, understanding the performance parameters of the vacuum pump is very necessary. The composition of the vacuum pump 1, the ultimate pressure of the vacuum pump The ultimate pressure unit of the pump is Pa, refers to the pump at the entrance with a standard test cover and work under the provisions of the conditions, without the introduction of normal gas work tends to the lowest stable pressure. 2, the return rate of the 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. 3, the suction rate of the vacuum pump Pump suction rate unit is m3 / s or l / s, is the pump equipped with a standard test cover, and work in accordance with the provisions of the conditions, the gas flow from the test cover and the test cover The ratio of the equilibrium pressure measured at the specified location. Pump pumping speed. 4, the maximum pressure before the vacuum pump The maximum pressure before the vacuum pump unit pressure unit is Pa, which means more than the previous pressure can damage the pump. 5, the pumping speed coefficient The actual pumping speed of the pump at the entrance by the molecular effusion calculated theoretical ratio of pumping speed. 6, the starting pressure of the vacuum pump Vacuum pump starting pressure unit Pa, it refers to the pump start without damage and the pressure when pumping. 7, the allowable amount of water vapor The allowable amount of water vapor is kg / h, it refers to the pump under normal environmental conditions, gas pump can be removed in the continuous operation of the water vapor mass flow. 8, the maximum allowable water vapor inlet pressure Maximum allowable water vapor inlet pressure unit is Pa. It refers to the maximum inlet pressure of water vapor that can be extracted by the gas-operated pump under continuous operation under normal environmental conditions. 9, the maximum working pressure of the vacuum pump The maximum working pressure of the vacuum pump unit is Pa, it refers to the maximum intake pressure corresponding to the inlet pressure. Under this pressure, the pump can work continuously without deterioration or damage. Through the above, we have a certain understanding of the meaning of the performance parameters of the vacuum pump, in the future there will be no small help in the purchase. 10, compression ratio Compression ratio refers to the pump for a given gas outlet pressure and inlet pressure ratio. Vacuum pump performance parameters for the industry to understand the product has a direct impact, focusing on the accumulation of information in this area, for understanding the development of the entire industry is bound to be beneficial.
