The liquid ring vacuum pump may have the phenomenon of pumping when it is used, which has a certain impact on our normal use. The following is a brief introduction to the skills of dealing with the phenomenon of pumping:
1. For high liquid ring vacuum pump, it can't directly discharge the atmosphere. If the direct discharge of the air, the pressure difference between the suction port and the exhaust port of the liquid ring vacuum pump will be too large, which will overload the liquid ring vacuum pump. In order to ensure the high vacuum, it is necessary to ensure the space between the rotors of the liquid ring vacuum pump.
2. When liquid ring vacuum pump is used, it is necessary to set up a front stage pump. The liquid ring vacuum pump is started when the pressure in the system is sucked to a certain range by the front stage pump. In this way, the overload phenomenon of liquid ring vacuum pump can be avoided. The liquid ring vacuum pump with water ring, rotary vane liquid ring vacuum pump, slide valve type liquid ring vacuum pump and reciprocating liquid ring vacuum pump can be used to discharge the atmosphere directly Empty pump.
3. As the rotor of the liquid ring vacuum pump keeps turning, the absorbed gas is sucked into the space between the rotor and the pump shell from the air inlet, and then is discharged through the exhaust port. Because the space is fully closed after suction, the gas in the pump chamber does not shrink and swell. However, when the top of the rotor turns over the edge of the exhaust port, and the space is connected with the exhaust side, the gas pressure on the exhaust side is high A part of the gas recoils into the space, causing the gas pressure to rise abruptly. When the rotor continues to change, the gas is discharged from the pump.
