摘　　要：隔膜泵是远程料浆输送设备工艺系统中的“心脏”设备,特别是高磨蚀、高浓度固液两相介质的长距离管道化输送系统中,更是其他泵类无法替代的,隔膜泵结构简单、坚固耐用,大部分的加工件难度较低,易于操作;动力端是整个隔膜泵技术难点最多的部件,其中包括了曲轴、连杆、活塞缸、十字头等相对精密的零件,特别是曲轴一般较大,需要特定的设备才能完成加工;本文通过对动力端的结构进行改造,目的是降低关键零件的加工难度,使其更加容易制造,从而降低成本,提高效率。Diaphragm pump is a“heart”equipment in the remote slurry transportation system.Especially in the long-distance pipeline transportation system of high abrasion and high concentration of solid-liquid two-phase medium,diaphragm pump is irreplaceable by others.Diaphragm pump is of simple structure,sturdy and durable,easy to operate,and most of the parts are easy to be fabricated;the power end is the part with most technological difficulties of the entire diaphragm pump,including relatively precise parts such as crankshafts,connecting rods,piston cylinders,crossheads,etc.Especially for crankshafts,it re-quires specific equipment to complete the processing.This paper discusses the structural transformation of the power end to reduce the difficulty of processing key parts,thereby reducing costs and improving effi-ciency.
