凸轮转子泵的选型及应用

摘要

在化工领域,考虑到一次投资成本和维修简便,很多装置内输送物料场合业主习惯选用离心泵的泵型比较多,而转子泵如螺杆泵、齿轮泵、凸轮泵、滑片泵等泵型应用较少,但随着化工产业的发展,有些工况下常规传统的离心泵已不能满足或并不适用复杂工况的使用要求,因机泵选型不合适造成机械密封等零部件出现频繁损坏或机械故障,设备维修的频率提高,维修成本随之提高.转子泵可以和离心泵之间形成互补,越来越多的应用在各个领域,主要对凸轮转子泵的选型和应用进行阐述.%In the field of chemical engineering,taking into account a single investment cost and easy maintenance,there are many types of pumps used by owners who are used to transporting materials in the plant.Rotary pumps such as screw pumps,gear pumps, cam pumps,vane pumps,etc.There are few applications,but with the development of the chemical industry,conventional centrifugal pumps under some conditions can no longer meet or do not meet the requirements for the use of complex conditions.Mechanical pumping and other components appear due to improper pump selection.Frequent damage or mechanical failure,the frequency of equipment maintenance increases,and maintenance costs increase.In fact,various types of rotor pumps can complement each other in centrifugal pumps and are being used in more and more applications in various fields.This article focuses on the selection and application of a type of rotor-pump rotor pump.
