Choosing the right water ring vacuum pump
Water ring vacuum pump is a kind of device which can produce, improve and maintain vacuum in a closed space by various methods. In the selection process, we need to refer to several performance parameters to select a suitable water ring vacuum pump. The specific parameters are as follows:
1. Ultimate pressure
The ultimate pressure unit of water ring vacuum pump is PA, which means that the vacuum pump is equipped with a standard test cover at the inlet and operates according to the specified conditions, and tends to a stable minimum pressure without introducing gas for normal operation.
2. Extraction rate
The unit of pumping rate is m3 / s or L / s, which refers to the ratio of the gas flow through the test cover and the equilibrium pressure measured at the specified position of the test cover when the vacuum pump is equipped with a standard test cover and operates according to the specified conditions. Referred to as the pumping speed of the pump.
3. Air extraction
The pumping capacity unit of water ring vacuum pump is pam3 / s or PAL / s. It refers to the gas flow at the pump inlet.
4. Starting pressure
The starting pressure of vacuum pump is PA, which refers to the pressure when the pump starts without damage and has the function of pumping.
5. Pre pressure of water ring vacuum pump
The former pressure unit of vacuum pump is PA, which refers to the outlet pressure of vacuum pump whose exhaust pressure is lower than one atmospheric pressure.
6. The maximum front pressure of water ring vacuum pump
The unit of the maximum front pressure at the water ring vacuum pump port is PA, which means that it exceeds the front pressure that can damage the pump.
In a word, the main parameters of water ring vacuum pump include limit pressure, pumping rate, pumping capacity, starting pressure, front pressure, etc. through these parameters, we can understand the water ring vacuum pump equipment, which can be more handy in use.
