Use Features: ZJP Roots vacuum pump has a large pumping speed at low inlet pressure, and have automatic anti-overload function. However Roots vacuum pump manufacturers, due to the structure of this type of pumps are dry-type gap seals, in order to obtain a certain degree of vacuum pumping speed and reduce regurgitation, must be reduced Roots vacuum foreline pressure, so there must be pre-vacuum pump when using connected in series, the first stage pump pumped Hou Luoci certain vacuum pump supply price, and then start the Roots pump, this is more cost-effective, according to actual needs, can choose different vacuum pump as a backing pump, such as pump seals, hydraulic ring pumps. It is worth mentioning that the Roots vacuum phone manufacturers, when elected by a liquid ring pump as a backing pump, especially for a lot of need for pumping condensable gas. ZJQ series of air-cooled Roots vacuum pump, is the basis of ZJ series Roots vacuum pump on the increase in bypass gas cooling system derived from new products. Due to its special design, it can be in high differential pressure and high compression ratio of long-term reliable operation. Cooling gas enters from both sides of the pump suction chamber of the pump, the pump will not compress gas and overheating, but no effect on the pumping performance of the pump. Each pump motor is cooler and the necessary accessories, coolers and motor specifications are based on different operating conditions may be. The pump can be used alone or in combination with liquid ring vacuum pump and vacuum pump series into common roots units, to achieve a higher degree of vacuum to meet various process requirements.
