Equidistant Pitch Screw Vacuum Pump

NEG Isometric Screw Vacuum Pump

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.

Main feature

1, compact structure, small footprint.

2, no oil in the pump chamber, no pollution to the vacuum system, improve product quality.

3, there is no oil in the pump chamber, to solve the problems of oil emulsification and frequent replacement of working fluid, frequent maintenance and maintenance, and save the use of costs.

4, no waste water, waste oil discharge, no pollution to the environment.

5, can remove a large amount of water vapor and a small amount of dust gas. After adding accessories, it can also remove flammable, explosive and radioactive gases.

6, the limit vacuum is high, can replace most of the Roots water ring and Roots reciprocating vacuum unit.

7, pump chamber and screw surface can be plated sickle and infiltration of alloy coating treatment, can be removed a lot of water vapor and a variety of corrosive media.
