泵的吸入管入口端应高于泥浆池底约300mm,而且吸入管内径必须一 致,吸入管的入口端不能正对泥浆池的入口(对泥浆罐也是如此)。 The inlet port of the suction line should be 300mm higher than the bottom of the mud pit and the internal diameter of suction line should be identical, Furthermore, the inlet port of suction line should not face the inlet of mud pit (so does the mud tank). 剪销安全阀必须安装成可直接与泥浆接触,并且将安全阀排出端 用无缝钢管直接引到泥浆罐,这条管线应尽可能少一些转折。若转弯 应使弯头大于120°,不允许把安全阀的排出管线接到泵的吸入管上, 在排出管路与安全阀之间不许安装任何型式的闸门。 When install the Shear safety valve, it should contact with mud directly, and the outlet end of safety valve should be connected to the mud tank with seamless steel pipe, whish should try to have fewer swerves (elbow). If there is a swerve, the bend angle should not be less than 120°. The discharge line of safety valve should not be allowed to connect to the suction pipe of mud pump. And also, between the discharge pipe and safety valve should not install any valve.
