爱什水泵公司是设计制造离心式杂质泵的主要公司之一。由于大多数杂质泵的抽送工质都含有磨粒,因而其另部件差不多都用镍硬铸铁(一种含镍铬成分的白口铁)来制作,以期获得良好的抗磨性能。镍硬铸铁是一种在工业中比较常用但又难于进行机械加工的材料。它具有与淬火钢相似的马氏体基体组织。 Aish pump company is to design and manufacture of centrifugal impurities pump one of the major companies. Since most of the pumping fluids in the impurity pumps contain abrasive particles, almost all of their other components are made of nickel hard cast iron, a white iron with a nickel-chromium composition, for good wear resistance. Nickel hard cast iron is a more commonly used in the industry but difficult to machine materials. It has martensite matrix similar to hardened steel.
