离心泵应用量大面广,占泵类产品的80%以上。在多年的研制、试验及外修工作中,我们发现许多用户对离心泵常见的故障,尤其是运行中的故障,还不能完全排除。因此,将离心泵常见故障诊断及排除方法介绍如下,供用户参考。 1.固有故障如结构设计、工艺过程不合理,材质强度不够或用不符合要求的代用材料制造零件,加工设备精度太低,检验或试验中操作人员不认真,转动、非转动部件之间的径向、轴向间隙不符合标准等。
Centrifugal pump widely applied, accounting for more than 80% of pump products. In many years of development, testing and external repair work, we found that many users of centrifugal pumps common faults, especially in operation, can not be completely ruled out. Therefore, the centrifugal pump common fault diagnosis and troubleshooting are described below, for the user reference. 1. Inherent faults such as structural design, process unreasonable, material strength is not enough or substandard substituting materials for the manufacture of parts, processing equipment, accuracy is too low, the test or test operators are not serious, rotating, non-rotating parts between Radial, axial clearance does not meet the standards.
