YLZJ roots vacuum pump

Detailed introduction

Product Overview
YLZJ series roots vacuum pump is the use of two figure-8 rotors installed perpendicular to each other on a pair of parallel shafts, by a pair of gears with a transmission ratio of 1:1 for reverse synchronous rotation, between the rotor, between the rotor and the inner wall of the pump cavity to maintain a fixed gap, high-speed operation, so as to complete the process of suction and exhaust, to achieve the purpose of extracting the gas in the system.

This series of pumps are made by imported processing centers, the pump body, both end faces and both end covers are sealed with 0 rings, and the cylindrical pin positioning holes are processed at one time, and the parts are interchangeable and easy to maintain.

Roots vacuum pumps cannot be used alone, only tandem backing pumps. Different vacuum pumps can be selected as backing pumps, such as screw pumps, rotary vane pumps, liquid ring pumps, etc. When the screw pump and liquid ring pump are selected as the backing pump, it is especially suitable for occasions where a large amount of condensable gas needs to be extracted.

 

Product features
: vibration, low
noise, no friction in the pump, no lubrication, no oil in the pump working chamber can obtain a clean vacuum, avoid oil vapor pollution, vacuum system
gas in the pump cavity vertical flow, conducive to the extraction
of gas dust and condensation is completely symmetrical and dynamic balance rotor operation is
Compact structure, small size, can be installed
horizontally or vertically, drive power is small, low
operation and maintenance costs, the use of air cooling structure, to ensure smooth operation
, fast start-up, can reach the limit pressure
in a short time, can do electroless nickel plating, Hastelloy plating, spray fluorine coating treatment for the gas circulation part, can resist all kinds of acid, alkali organic solvent corrosion

 

Product use
is widely used in petroleum, chemical, plastics, electronics, semiconductors, pesticides, metallurgy, textiles and medicine.
