This pump is a two-stage high-speed oil seal rotary vane vacuum pump. It is equipped with air ballast valves. Its function is to fill the exhaust space with a certain amount of air when the valve is opened, thereby reducing the proportion of steam partial pressure in the total exhaust pressure. Because the partial pressure of steam is lower than that of saturated steam, which corresponds to the working temperature of the pump, steam can be discharged from the pump by filling air to avoid condensation of the steam in the pump oil and to prevent the oil from being emulsified by condensation steam, thus prolonging the useful lift. However, when the ballast valve is opened, the limit vacuum degree of the pump will decrease and the temperature of the pump will rise.

 
This type of pump has the outstanding achievements of small volume, light weight, quiet operation and easy start-up. It also provides a device to prevent oil absorption and shaft seal oil from polluting the environment.

application:
 
This pump is one of the basic equipment for discharging sealed containers. It can be used not only as a main separate pump, but also as a front-stage pump of booster pump diffusion pump and molecular pump, or as a maintenance pump of vacuum system and a pre-pump of different types of pumps. Therefore, it can be used in the electric vacuum industry, vacuum bottle manufacturing, vacuum welding and as an accessory to precision instruments or instruments that need vacuum. Because of its small size, light weight and quiet, it is more suitable for laboratory use. Operation.
 
2. The pump is allowed to work continuously for several hours at atmospheric pressure of 5 C-40 C and intake pressure of 1 230 PA. The pump gas of the pressure valve with relative humidity greater than 90% should be opened.
 
3. Open the intake port to the atmosphere so that the pump can not work for more than one minute.
 
4. Pumps are not suitable for pumping peroxides, poisons, explosive and corrosive gases, and gases that react with pump oil contain dust particles.
