Cooling Technique of Vacuum Pump
When
the vacuum pump carries out energy conversion, there is always a small part of
the loss converted into heat. It must continuously radiate the heat through the
motor shell and surrounding media. This process of heat emission is called
cooling. Here is a brief introduction to the cooling techniques of the vacuum
pump.
1、 Air cooling:
That
is to say, the air inhaled by the interstage or two-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, and there are oil holes and oil diameter shaft heads at both
ends of the shaft of the vacuum unit, which are driven in, 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 delivery pipe at the inlet of the vacuum
pump, and take the heat of the rotor away with the cooling oil dropping evenly.
4、 Cooling:
Vacuum
pumps produce heat due to the delivery and compression of gas, which must be
transmitted from the rotor to the shell.
