BZJ series two-stage Roots pump (Roots pump) Roots vacuum supplier, the company is based on 2ZJ series on single-stage Roots pump Roots vacuum outlets, carefully researched successfully developed a new generation of replacement products, each indicators have reached similar foreign products. Currently in China, Roots vacuum unit of the main ways to achieve high vacuum multi-series Roots pump before the pump coupled, multiple Roots pump Roots vacuum pump series is a relatively flexible production and supply, with extensive use of Roots vacuum pump and improve the technical requirements of the relevant industry, there is a growing need for an easy to use and maintain, and reliable operation of the new Roots vacuum pump to improve their productivity and reduce production costs. The principle and structure Roots vacuum pump is mainly composed of a pair of high-speed synchronous rotation of the "8" shaped rotor and two semicircular pump chamber components. The pump alone can not exhaust, must be with a pump (such as claw-type pumps, screw pumps, rotary piston pump, water pump, oil ring pumps, etc.) used in tandem. Front air intakes on the front-stage pumps in series Roots vacuum pump unit and increase the degree of vacuum before the pump, the effective range can greatly improve the pumping rate. Roots vacuum pump ultimate pressure is determined by the pre-pump. Roots pumps are widely used in vacuum casting, vacuum distillation vacuum melting, vacuum degassing, vacuum coating industry and the chemical and pharmaceutical industry, vacuum drying. Pump is not sensitive to small amounts of dust. Roots vacuum pump supplier, Xi'an Roots vacuum pumps, Zhucheng East Han Machinery Co., Ltd. provided by Zhucheng East Han Machinery Co.
