ZJ/ZJB系列罗茨真空泵(简称 罗茨泵)是指泵内装有两个相反方向同步旋转的叶形转子,转子间、转子与泵壳内壁间有细小间隙而互不接触的一种旋转式变容真空泵(须与前级泵组台方可使用),是目前获得中、高真空主要抽气设备之一.

ZJB型带溢流阀罗茨真空泵的不同之处就是ZJB型泵进排气口连通, 在通道上垂直的装着—个自蜇阀  ,其作用是使排气口和进气口的压力差始终保持在一个可控的数位内,该数值是泵运转时所允许的*高压力差。因此,这种阀实际上就是一种过载自动保护阀。

罗茨真空泵在石油、化工、塑料、农药、汽轮机转子动平衡、航空航天空间楼拟等装置上得到了长期运行的考验,同时也广泛用于石油、化工、冶金、纺织等工业.

ZJ/ZJB series Roots vacuum pump (referred to as: Roots pump) refers to a kind of rotation in which the two rotors are rotated synchronously in opposite directions, and there is a small gap between the roto and the inner wall of the pump casing without contact with each other. The variable displacement vacuum pump is one of the main pumping equipments for medium and high vacuum.

The difference between the ZJB type relief valve and the Roots vacuum pump is that the ZJB pump is connected to the exhaust port, and a self-weight valve is vertically mounted on the passage. The function of the pressure difference between the exhaust port and the intake port is always maintained. Within a controllable value, this value is the highest pressuredifferential allowed for pump operation. Therefore, this valve is actually an overload automatic protection valve.

Roots vacuum pumps have long-term operation in petroleum, chemical, plastics, pest1c1des, turbine rotor dynamic balance, aerospace space simulation and other devices, and are also widely used in petroleum,chemical, metallurgical, textile and other industries.
