目前,我国有很多大型泵站使用立式轴流泵,而它的配套动力多数为立式悬吊型同步电机。拆卸推力头是整个机组大修的关键之一。通常用厂家配套的专用工具,加上自制的吊扳手,旋转螺母使螺杆升高,将推力头与大轴分开。这对一般配合较松的推力头是可行的,但对配合较紧的推力头,只有通过加长扳手,增加扳动人员来进行。如遇配合特别紧的,如此进行下去,不但会损坏工具,而且还 At present, there are many large-scale pumping stations in our country which use vertical axial-flow pumps, and most of them are vertical suspension-type synchronous motors. The removal of the thrust head is one of the keys to overhauling the entire unit. Usually with the manufacturer’s special tools, coupled with homemade hanging wrenches, rotating nuts to screw, the thrust head and the shaft separate. This is generally with the loose thrust head is feasible, but with the tight thrust head, only by increasing the wrench, increase the staff to pull. In case of special tight cooperation, so go on, not only will damage the tools, but also
