(Summary description)There are small holes in the compression chamber of the oil seal machinery China rotary vane vacuum pump, and a regulating valve is installed. When the valve is opened and the intake air volume is adjusted, the rotor rotates to a certain position through which the air is mixed into the compression chamber to reduce the compression ratio so that most of the vapor will not condense and will be discharged together with the mixed gas outside the pump. The valve that plays this role is called a gas ballast valve.

There are small holes in the compression chamber of the oil seal machinery China rotary vane vacuum pump, and a regulating valve is installed. When the valve is opened and the intake air volume is adjusted, the rotor rotates to a certain position through which the air is mixed into the compression chamber to reduce the compression ratio so that most of the vapor will not condense and will be discharged together with the mixed gas outside the pump. The valve that plays this role is called a gas ballast valve.
Reason: Since the pumping process of the rotary vane vacuum pump is a compression process, when there are condensable gases such as water vapor, if the saturated vapor pressure is reached before being discharged from the pump chamber, they will be in the oil Condensation, resulting in emulsification and deterioration of the pump oil, deterioration of lubrication and sealing performance, and the condensate will become gaseous again in the suction chamber, thereby reducing the vacuum level.
The principle of China rotary vane vacuum pump: the pressure of the exhaust chamber consists of two parts: air partial pressure and steam partial pressure. Bleeding occurs only when the sum of the two is sufficient to overcome atmospheric pressure and the elasticity of the exhaust valve.
The advantages of China rotary vane vacuum pump gas ballast valve: meet the requirements of pumping out moist air without water vapor contaminating the oil; the ultimate pressure of the vacuum pump can be restored; purify the pump oil of the vacuum pump; restore the ultimate vacuum degree of the vacuum pump.
The noise of the China rotary vane vacuum pump usually refers to the noise level measured under the ultimate vacuum when the pump temperature is stable. Including the noise of the pump itself and the noise of the motor.
