China XD rotary vane vacuum pump

The China XD rotary vane vacuum pump is a type of positive displacement pump,which works based on the continuous operation of the rotary vane in the pump chamber.The pump is mainly composed of the pump body,rotor,rotary vane,and driving device.The pump body is generally made of cast iron or stainless steel,while the rotor is eccentrically installed inside the pump body and is tangent to the fixed true line on the surface of the pump body.There are several radially sliding rotor blades installed in the rotor slot.
When the rotor begins to rotate,the rotor slides tightly against the inner wall of the pump body under the action of centrifugal force.As the rotor continues to rotate,the rotor divides the pump chamber into multiple working chambers with periodically variable volumes.The volume of these working chambers varies periodically with the rotation of the rotor,thereby achieving the processes of suction,compression,and exhaust.
Specifically,when the working chamber volume expands,the XD rotary vane vacuum pump sucks in gas through the suction port.As the rotor continues to rotate,the volume of the working chamber gradually decreases,compressing the inhaled gas.Then,when the passage between the working chamber and the exhaust box is opened,the compressed gas is discharged from the pump body.Every time the rotor rotates,this process will be repeated multiple times to achieve effective vacuum extraction.
The China XD rotary vane vacuum pump has the advantages of large pumping volume,high efficiency,low noise,and low vibration.Its flow rate can reach 30-40 L/s,widely used in vacuum packaging in the food manufacturing industry,vacuum compression packaging in the textile industry,vacuum drying and distillation in the chemical industry,vacuum fixtures in mechanical processing,vacuum suction in hospital operating rooms,and vacuum forming in the plastic industry.
In addition,the operation of China XD rotary vane vacuum pump is simple,stable,and easy to maintain.Users can maintain the effective operation of the equipment through simple maintenance operations,such as regularly checking the oil level and oil pollution,timely replacing the vacuum pump oil and oil filter,etc.This not only improves work efficiency,but also reduces additional labor and material costs.
With the continuous advancement and innovation of technology,China XD rotary vane vacuum pumps will continue to play an important role in multiple industries.Its effective and reliable working principle and wide application prospects undoubtedly inject new vitality into the development of China's industrial manufacturing field.
