Roots vacuum pump is a positive displacement Roots vacuum pump production and supply, also known as a mechanical booster pump price Roots, the advantage of having a high pumping speed at low inlet pressure, is currently available in a high vacuum pump One of the main pump. Roots Roots vacuum pump does not allow direct pressure differential work, otherwise it will overload or overheat and damage the roots vacuum pump, Roots vacuum pump must therefore use a reasonable selection of pre-pump, install the necessary protective equipment. 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. Chengdu Roots Roots vacuum pump price _ _ Zhucheng East Han Machinery Co., Ltd. by John Zhucheng East Machinery Co., Ltd.
