The cooling of vacuum pump helps the efficient use of the equipment, but its cooling should be under certain conditions. The following is the relevant introduction.
1. As for the medium with temperature lower than 120 ℃, generally no special cooling system is set, and the medium of vacuum pump itself is mostly used for smoothing and cooling. The suspension structure can be selected to make the upper limit of temperature reach 140 ℃ ~ 160 ℃. It is worth mentioning that the medium easy to crystallize or rich in particles should be equipped with a sealing surface flushing pipeline (interfaces are generally reserved in the design).
2. For the medium above 120 ℃ and within 300 ℃, generally, the vacuum pump cover must be equipped with a cooling chamber, and the sealing chamber should also be connected with the cooling liquid. When the cooling liquid is not allowed to penetrate into the medium, it should be connected after the medium is cooled (it can be completed through a simple heat exchanger).
To cool the vacuum pump, it is necessary to cool it according to the temperature of the medium, and pay attention to the correct method.
