摘要
针对ZW系列自吸排污泵存在易堵塞叶片和耐磨板不易更换的问题,进行了改进设计。简述了新型无堵塞自吸污水泵的特点和设计思想,分析了该泵的结构特点,提出了该泵的水力设计和结构设计方法,并研究了前置供水通道仓、转子部件以及回流孔对自吸污水泵的影响。最后,设计试制了新型无堵塞自吸污水泵的样机,并对其进行了试验。研究结果表明,新型自吸排污泵具有无堵塞性能好、自吸时间短、耐磨性强、可靠性高、使用维修方便等特点,泵的性能曲线符合设计要求,达到了预期设计目标,为今后相关工作提供了有益的参考。
Aiming at the problems of easy clogging blade and uneasy replacing wear plate for the ZW series self-priming sewage pump,improved design was carried out.The features and design concepts of new non-clogging self-priming sewage pump were introduced.The configuration of the pump was analyzed and the method of hydraulic and structural design was given.The influences of the front water supply channel warehouse,rotor component and circumfluence hole on self-priming sewage pump were studied.The prototype of new non-clogging self-priming sewage pump was designed and trial-manufactured,and the test verification of prototype was carried out.The results show that the pump has the advantages of good non-clogging performance,short self-priming time,strong wear resistance,high reliability,easy to use and maintenance,etc..The pump performance curve accords with the design requirement.The design target is reached and an useful reference for future related work is provided.
