Liquid Ring Vacuum Pump Four Cooling Ways

Some people may not quite know what is the cooling of liquid ring vacuum pump. In the process of energy conversion, a small part of the loss of the vacuum pump is always converted to heat. Therefore, it must continuously emit heat through the motor shell and surrounding medium. This process of heat emission is called cooling.


Here are four common methods of cooling.


1. Internal cooling of rotor:


In order to make the liquid ring vacuum pump work under higher pressure difference, a more effective cooling method can be adopted, i.e. the rotor is cooled by circulating oil. Oil holes and oil diameter axle heads are penetrated at both ends of the shaft of the vacuum unit, and then discharged from the other end through the inner wall of the rotor.


2. Air cooling:


That is, the air inhaled by an intermediate or two-stage pump is compressed and transmitted through a combined muffler with comprehensive absorption and phase difference.


3, cooling:


The liquid ring vacuum pump produces heat by conveying and compressing gas, which must be transmitted from the rotor to the shell.


4. Oil film cooling of rotor:


The cooling method is to connect an oil pipeline at the inlet of the liquid ring vacuum pump, and take away the heat of the rotor with uniform dropping cooling oil.


When the temperature of liquid ring vacuum pump is too high, different cooling methods can be adopted according to the different temperature. When problems arise, they should be solved in time to avoid unnecessary losses as far as possible.
