Here are some tips to teach you how to use vacuum pump:

Liquid ring vacuum pump pumping treatment skill

The liquid ring vacuum pump may appear the phenomenon of pumping when it is used, which has a certain impact on our normal use. Here is a brief introduction to the skills of dealing with the phenomenon of pumping:

1. For high liquid ring vacuum pump, the air can not be discharged directly. If the air is discharged directly, the pressure difference between the suction port and the exhaust port of the liquid ring vacuum pump will be too large, so that the liquid ring vacuum pump will be overloaded. In order to ensure that the high vacuum can be reached, it is necessary to ensure the space between the rotors of the liquid ring vacuum pump.

2. When the liquid ring vacuum pump is used, it is necessary to set up a front-end vacuum pump. When the pressure in the system is sucked to a certain range by the front-end vacuum pump, the liquid ring vacuum pump can be started again. In this way, the overload phenomenon of the liquid ring vacuum pump can be avoided. The front-end pump can choose the liquid ring vacuum pump of water ring type, the rotary vane liquid ring vacuum pump, the slide valve liquid ring vacuum pump, the reciprocating liquid ring vacuum pump and other liquid ring vacuum pumps that can directly exhaust the atmosphere Air vacuum pump.

3. As the rotor of the liquid ring vacuum pump continuously turns, the absorbed gas is drawn into the space between the rotor and the vacuum pump shell from the air inlet, and then discharged through the exhaust port. As the space is completely closed after suction, the gas in the vacuum pump cavity does not shrink and expand. However, when the top of the rotor turns over the edge of the exhaust port, and the space is connected with the exhaust side, because the gas pressure at the exhaust side is high, the air pressure at the exhaust side is high A part of the gas flows back into space, which makes the pressure of the gas increase sharply. When the rotor continues to change, the gas is discharged out of the vacuum pump.
