ADVANTAGES OF DRY SCROLL VACUUM PUMP:
Dry scroll vacuum pump is a kind of oil-free mechanical vacuum pump. It has the advantages of simple structure, large effective volume utilization coefficient, large compression ratio, stable pumping speed, high vacuum, small driving torque, small power change, low vibration noise, high reliability in a wide pressure range.
DRY SCROLL VACUUM PUMP PRINCIPLE:
The basic principle of the dry scroll vacuum pump is that the gas is compressed in the crescent compressor cavity composed of the vortex rotator and the vortex stator, the vortex stator is fixed on the periphery of the rack, an air inlet is opened on the periphery of the vortex stator, and an air outlet is opened in the center of the vortex rotator and the vortex stator. The vortex lines of the vortex stator and the vortex rotator are basically the same. The two phases are staggered 180 degrees. As a result, a series of crescent compression cavities are formed between the two vortices. When the vortex rotator rotates, one side of the crescent compression chamber moves toward the center, and its volume side continuously decreases, thus completing the suction, compression and exhaust process of the turbine dry pump.
With the rapid development of semiconductor, new materials and bio-pharmaceutical industries, the theory of vortex is becoming more and more mature, and people urgently need clean and oil-free vacuum environment.
Because of its superior performance, turbo-pumps have been widely used in many industries. Especially with the wide use of turbo-molecular pumps, composite molecular pumps and cryopumps, people are looking for an oil-free pre-vacuum pump that matches these completely oil-free high vacuum pumps requirement.
