The working principle of sliding valve vacuum pump is to use sliding valve mechanism to change the volume of suction chamber. Like rotary vane pump, it is a variable-volume gas transmission pump, and its scope of use and operating conditions are basically the same as rotary vane pump.
Slide valve pump is often used in large vacuum equipment because of its structural characteristics and much larger capacity than rotary vane pump. There are two types of sliding valve pumps, single-stage and double-stage. The sliding valve pumps whose pumping speed is greater than or equal to 150L / s mostly adopt single-stage type.
· H-150FSliding Valve Vacuum Pump
This pump refers to similar products at home and abroad, combined with the actual domestic use environment, designs and improves on the basis of the original H-150 vacuum pump, and manufactures H-150F sliding valve vacuum pump, which is especially suitable for the dust-rich and impurity-rich environment such as quartz, artificial marble and resin handicraft industries. After a year of on-site use, it has been proven that the pump can effectively help solve the problem of oil pollution. In the normal maintenance state , there is no maintenance record in one year, which brings direct economic benefits to users and is highly praised. In addition, an oil and gas separator is installed at the exhaust port to recover the oil to the sub-tank without oil injection, which effectively reduces the pollution to the surrounding environment and achieves the effect of both benefit and environmental protection.
