ZJP Series Roots Vacuum Pump Applications:

 
ZJP series Roots vacuum pump is a kind of Volumetric Vacuum pump, also known as mechanical booster pump. It is one of the main pumping equipment to obtain medium and high vacuum pumps at present. Its working principle is similar to Roots blower. It uses two 8-shaped rotors to rotate synchronously in the pump housing to complete the process of suction and exhaust.
 
The greatest advantage of ZJP series Roots vacuum pumps is that they have a higher pumping rate at a lower inlet pressure and can achieve a relatively high limit vacuum. Because the pump is directly used for pumping main parts such as pump shell, rotor and end cover, there is no relative movement contact, so the pump has stable operation performance, long service life and low maintenance cost. At present, this kind of pump is widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum spraying, vacuum drying, vacuum power experiment, chemical pharmaceuticals, electro-vacuum device manufacturing and other vacuum treatment within the vacuum range that this pump can achieve.
 
In view of the process of extracting a large amount of water vapor and solvent in chemical and pharmaceutical industries, our company has improved the sealing structure of ZJ series Roots vacuum pump chamber and bearing chamber, greatly reduced the emulsification phenomenon of bearing chamber and gear chamber pump oil, and made ZJ series Roots vacuum pump more suitable for extracting a large amount of water vapor and solvent with water ring vacuum pump.
 
ZJP series Roots vacuum pump working conditions:
 
Roots vacuum pump can not be used alone. There must be a front vacuum pump in series. It can not start work until the pressure in the pumped system is pumped to the inlet pressure that Roots vacuum pump can bear. Otherwise, it will be damaged by overload and overheating.
