SDP variable pitch screw vacuum pump
Product features
SDP variable pitch screw vacuum pump product parameters, also known as dry screw vacuum pump, is the use of gear transmission synchronous reverse rotation of the mutual meshing and non-contact variable pitch left screw and right screw for high-speed rotation, using the pump shell and the mutual meshing screw to separate the spiral groove into multiple spaces, multi-stage compression chamber, gas transmission movement in different grooves (cylindrical deformation pitch) 。 After fine dynamic balance, the two screws are supported by bearings and installed in the pump shell. There is a certain gap between the screw and the screw, and between the screw and the pump body. When the pump works, there is no friction between each other, the operation is stable, the noise is low, and the working chamber does not need lubricating oil. It can completely replace oil seal mechanical pump and water seal mechanical pump and become the main vacuum acquisition equipment of the new generation.
Main features
● Compact structure and small floor area.
● Because the gas is compressed in the pump, the power consumption is low.
● Because there is no oil lubrication in the vacuum chamber, the dust will not stay in the pump chamber, but will be discharged from the pump with the gas from the exhaust port. And solve oil emulsification and frequent replacement of working fluid, frequent maintenance and other problems, save the use cost.
● There is no internal valve in the pump chamber, which eliminates the possibility of failure due to internal valve, so it has strong ability to control dust and tar.
● No waste water, waste oil discharge, no pollution to the environment.
● The limit vacuum is high, which can replace most roots water ring and roots reciprocating vacuum units.
● The surface of pump cavity and screw can be treated with nickel plating and Hastelloy coating, which can remove a lot of water vapor and a variety of corrosive media.
