products:   ZJ、ZJB、ZJC、ZJBC系列罗茨真空泵

ZJ、ZJB、ZJC、ZJBC型罗茨真空泵是一种旋转实变容积式真空泵,又称机械增压泵,是目前获得中、高真空的主要抽气设备之一,其工作原理与罗茨鼓风机相似,是利用两个“8”字型转子,在泵壳内作同步转动,从而完成吸气和排气。 ZJB、ZJBC型带溢流阀罗茨真空泵与ZJ、ZJC型罗茨真空泵的不同之处是ZJB、ZJBC型泵进排气口连通,在通道上垂直地装着一个自重阀,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制的数值内,该数值是泵可靠运转时所允许的最高压力差值。因此,这种阀实际上就是一种过载自动保护阀。 ZJC、ZJBC型罗茨真空泵是本公司自行开发设计的第二代罗茨真空泵。其体积小、重量轻、运行平稳、低噪音。上下垂直与侧面流道、低泄漏率。骨架油封与机械密封可以任意选用。对内密封冲注保护气体,防腐蚀。可采用风冷和水冷方式满足不同工况要求。ZJBC型带溢流阀罗茨真空泵溢流阀是内置结构,不同ZJB型,外形同ZJC没有差别。

The series ZJY roots vacuum pump is with overflow valve: A gravity valve installed between the suction and exhaust part of the pump opens automatically when the pressure difference is over the weight of the valve, keeping the pressure difference always at a fixed controllable value. This value is the allowable highest pressure difference to ensure the pump work normally. The roots vacuum pump with overflow valve is a kind of overload self-protective pump.
