浅谈提高离心水泵性能的有效途径
|
摘要
针对目前矿井使用的单级及多级离心泵使用存在问题,从设计制造方面、安装试验和后期维修方面提高离心泵性能的角度出发,叙述了离心泵过流部位尺寸偏差对泵性能的影响,从中看出离心泵的性能取决于设计质量、制图质量、铸件铸造、机械加工质量、装配质量等诸多因素,而且取决于它们的相互配合。探究结果表明,任何一个给定的设计因素对泵的性能可能有很大的影响,影响的程度则取决于所有其他因素的相对重要性和相互配合协调,因而在新产品试制当中发现性能有偏离标准要求时,要具体分析查找原因,找出关键性因素。离心泵在维修过程中,零部件的检测和装配细节如得到控制,完全可以将性能恢复到新出厂时的90%以上。
In view of the problems in the use of single-stage and multi-stage centrifugal pumps currently used in mines,the influence of the size deviation of the flow passage part of the centrifugal pumps on the performance of the pumps is analyzed from the aspects of design,manufacture,installation test and later maintenance. The performance of centrifugal pump depends on many factors,such as design quality,drawing quality,casting quality,machining quality and assembly quality. In the trial production of new products,when it is found that the performance does not meet the requirements of the standards,it is necessary to analyze and find out the reasons and the key factors. In the maintenance process of centrifugal pump,if the inspection and assembly details are controlled,the performance of centrifugal pump can be restored to more than 90%.
