Vacuum pump energy conversion, there is always a small part of the loss into heat, it must be through the motor shell and surrounding media constantly heat out, this heat dissipation process, known as cooling. And the vacuum pump will produce a certain amount of heat, if these heat can not be timely heat dissipation, a long time will affect the internal parts of the vacuum pump, or even damage. This will affect the normal operation of the fan, and even damage the fan.
The following EVP vacuum pump manufacturers analysis of vacuum pump cooling skills.
Vacuum pump, presumably we are not unfamiliar with it, but, vacuum pump can not exist a lot of oil. Indeed, vacuum pumps are widely used in many industries. Especially when the ability of removing condensable steam is not enough, or the solvent used can deteriorate the pump oil and affect the performance, or the vacuum system does not allow oil pollution. Therefore, the vacuum pump can not exist a lot of oil.
Professional vacuum pump maintenance manufacturers want to tell you that there are many cooling schemes for vacuum pump, and the appropriate cooling scheme is determined according to the heat output of different parts of the body. For example: when the working pressure of the vacuum pump is high, the temperature rises quickly and the temperature is high. The ordinary vacuum pump needs circulating water for cooling, so as to protect the fan from damage.
The key point is that EVP vacuum pump manufacturers analyze the cooling and cooling skills of vacuum pumps, mainly including four points:
1、 Air cooling:
That is, the air inhaled by the intermediate or double-stage pump is compressed and transmitted through the combined muffler with comprehensive absorption and phase difference.
2、 Internal cooling of rotor:
In order to make the vacuum pump work under a higher pressure difference, a more effective cooling method can be adopted, that is, the rotor is cooled by circulating oil, oil holes and oil diameter shaft heads are respectively set at both ends of the vacuum unit shaft, and then discharged from the other end through the inner wall of the rotor.
3、 Oil film cooling of rotor:
This cooling method is to connect an oil pipe at the inlet of the vacuum pump and take away the heat of the rotor with the cooling oil uniformly dripping down.
The vacuum pump produces heat due to conveying and compressing the gas, which must be transferred from the rotor to the shell and dissipated.
