Under the long-term use of the water ring vacuum pump unit, the equipment will emit heat. If the heat emitted in a certain period of time is too much, the equipment will be damaged to a certain extent. Therefore, we need to have certain treatment measures at this time. Today we will explain the four treatment methods about cooling for you.
1. Oil film cooling of rotor
The cooling method is to connect an oil pipe at the inlet of the water ring vacuum pump unit, and take the heat of the rotor away with the evenly dripping cooling oil.
2. Air cooling
The so-called wet vacuum pump, that is, the air inhaled by the interstage or two-stage pump is compressed, and then transmitted through a combined muffler with comprehensive absorption and phase difference.
3. Water cooling
The water ring vacuum pump unit generates heat due to the transmission and compression of gas, which must be transmitted from the rotor to the shell.
4. Internal cooling of rotor
In order to make the water ring vacuum pump unit work under a higher pressure difference, a more effective cooling method can be adopted, that is, the rotor is cooled by circulating oil, and there are oil holes and oil diameter shaft heads at both ends of the pump shaft, which are respectively driven in, and then discharged from the other end through the inner wall of the rotor.
