Abstract

改进的离心排水泵泵壳，涉及离心式排水泵部件，包括连接进水管的泵壳进水口端面，泵壳进水口端面呈锥形，通过改进泵壳进水口的端面结构，使泵在吸入空气后能保持正常工作，不产生“轰－轰”的连续回流与再排出噪音。

Description

改进的离心排水泵泵壳
技术领域
本发明涉及离心式排水泵部件，尤其是指离心排水泵的泵壳。
背景技术
市场上的离心排水泵技术，其泵壳的进水口端面通常为平面，使用时，当进水、出水位置都高于泵或单独出水位置高于泵，在液体排出将结束或等待迟缓结束或定时间结束时，泵进口会吸入空气或少量吸入空气，排出管内的液体由于空气进入后产生连续回流与再排出，空气会积聚在平面端面的角落处无法排出，这时就产生了“轰-轰”的连续回流与排出的噪音，随着技术领域行业标准的不断提高，这种声音超标或噪音量偏高使排水泵无法满足技术要求。
发明内容
本发明正是为了克服上述不足，提供一种改进的离心排水泵泵壳，通过把进水口处的泵壳端面由平面改为锥面，使泵在工作时吸入空气后能保持正常的工作状态，不产生“轰-轰”的连续回流、再排出的噪音，具体是这样来实现的：改进的离心排水泵泵壳，包括连接进水管的泵壳进水口端面，其特征在于泵壳进水口端面呈锥形。这种斜面式的泵壳进水口端面结构，适当增大了内腔存液量，减少了进水口直径，空气吸入后能沿斜面从进水口排出，降低噪音非常明显。
为了保证空气的及时顺畅排出，本发明的泵壳进水口锥形端面的内壁上开有凹槽，所述的凹槽连通进水口与泵壳内腔。凹槽能帮助锥面使吸入的空气被迅速排出，避免在泵体内空气与水的撞击，水在叶轮面上就不会被空气隔断，继续保持离心排出，排出管内的水不再产生回流。设置在锥形进水口端面内壁上的凹槽通常是均匀布设的。
本发明的泵壳进水口锥形端面可以是与泵壳呈连体结构，也可以根据不同的使用场合设计为组合拼结形式，即泵壳进水口锥形端面与泵壳呈分体结构，分体结构有利于将锥形端面的外部设计其它形状，比如设计带齿形状或多个小孔形状的多种过滤装置用以过滤进入泵体内的垃圾或异物。为了密封空气与阻止异物的进入，在组合拼接的缝隙中嵌有软性密封件。
本发明通过改进泵壳进水口的端面结构，并在锥形进水口端面上设置凹槽，使泵在吸入空气后能保持正常工作，不产生“轰-轰”的连续回流与再排出噪音。
附图说明
图1为本发明实施例1的结构示意图。
图2为泵壳进水口锥形端面示意图。
图3为本发明实施例2的结构示意图。
