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.
· HS-150Sliding Valve Vacuum Pump
In addition to the function of H-150, the pump is characterized by energy saving, environmental protection and less land occupation. Because of the improvement of its internal structure and H-150, the 11kw power of the matched motor is enough to meet the requirements and achieve the purpose of energy saving. The exhaust part is manufactured by foreign advanced oil and gas separation technology, so that when the pump is filled with air, the pollution of exhaust oil and gas can be effectively reduced and the environmental protection effect can be achieved. In addition, the pump is a vertical structure, occupying less space, beautiful appearance, is a relatively new and cost-effective vacuum pump products in the current market.
