Do you know the 10 important parameters of vacuum pump selection?
With the wider and wider use of the vacuum pump, customers need to choose the type of knowledge is also urgently needed in the industry according to the pressure scale under different circumstances and different industrial needs, the use of the type of vacuum pump parameters are not the same, then, what are the parameters of the selection of vacuum pump? Summary of the 10 important parameters, with a look at it!
1. Steam allowance of vacuum pump,
The allowable unit of steam is kg/h, it refers to the vacuum pump in the deformed standard huai standard huai, gas vacuum pump in the operation of the quality of steam can be removed.
2. Vacuum pumping efficiency of vacuum pump
Rate of the vacuum pump unit is m3 / s or l/s, and vacuum pump cover is equipped with standard experiment and standard work, in accordance with the relevant provisions from the experiment cover through the gas pressure and the location specified in the experimental test hood side have to balance the ratio of the pressure of work, referred to as “vacuum pump speed, unit for the m3 / a or l/s.
3. Vacuum pump pumping volume,
The gas flow through the vacuum pump inlet. The unit is pa.m3 /s or pa.l /s.
4. The ultimate working pressure of the vacuum pump,
When the vacuum pump is equipped with a standard test cover and operates in accordance with the specified standard, the minimum working pressure tends to be stable without introducing the normal operation of gas. Under the condition of not introducing the abnormal operation of gas, the industrial pressure is strong with a stable trend, and the pressure unit is Pa.
5. Starting working pressure of vacuum pump,
No damage for vacuum pump up and have a vacuum effect of job stress, Pa,
6. Pre-stage working pressure of vacuum pump,
Exhaust working pressure is lower than the outlet working pressure of a vacuum pump with atmospheric pressure. The unit is Pa.
7. Maximum working pressure of the vacuum pump,
The working pressure above which the vacuum pump will not work properly is called the maximum working pressure of the preceding stage, and the unit is Pa.
8. Maximum working pressure of vacuum pump,
The vacuum pump can work continuously without deterioration or damage under this working pressure.
9. Compression ratio of vacuum pump,
The ratio of the outlet working pressure of the vacuum pump to the inlet working pressure of the given gas,
10. The reflux rate of the vacuum pump,
The vacuum pump reflux rate unit is g/cm2.s. It refers to the vacuum pump according to the code huai operation, through the vacuum pump outlet unit area of the vacuum pump flow quality flow rate,
More than 10 vacuum pump selection parameters can you understand it, if you don’t understand can contact us for your detailed answers, every industry process even in different vacuum pump type selection is to be aware of, selection of the right to make mechanical energy efficient, so must be clear when use vacuum pump pump in the vacuum system in the bear’s homework tasks.
