vacuum system

Summarize
Screw type oil-free mechanical vacuum pump, also known as dry screw vacuum pump, is the use of gear transmission synchronous reverse rotation of the mutual mesh without contact with the left screw and the right screw for high-speed rotation, the use of pump shell and mesh helix will be separated into a number of Spaces, the formation of a number of stages, the gas in the equivalent of each groove (cylindrical pitch) for transmission movement. The two screws are finely balanced, supported by bearings, and installed in the pump shell. There is a certain gap between the screw and the screw, and the screw and the pump body. There is no friction between the pumps when they work, smooth operation, low noise, and no lubricating oil in the working chamber. It can completely replace oil-sealed mechanical pump and water-sealed mechanical pump to become a new generation of main vacuum acquisition equipment.
