Abstract

一种限流潜水电泵,包括潜水电泵,其特征是在潜水电泵叶轮下面的传动轴上装有限流套。在叶轮进口处增加一轴向限流套,通过控制限流套的外径,从而控制限流套与叶轮进口之间的过水面积,达到调节进水量的目的,防止电泵过载运行,运行安全可靠。

Description

一种限流潜水电泵
技术领域
本实用新型涉及一种泵,特别是一种限流潜水电泵。
背景技术
离心式潜水电泵在低扬程运行时,流量、功率会增大,当扬程低于一定范围时,电泵就会出现过载运行状态,如果将高扬程泵在低扬程下运行,将导致电泵过载烧毁。
发明内容
本实用新型的目的是为了解决上述技术问题,而提供一种防止过载运行,运行安全可靠的限流潜水电泵。
本实用新型的目的是这样实现的:一种限流潜水电泵,包括现有的潜水电泵,其特征是在潜水电泵叶轮下面的传动轴上装有限流套。
本实用新型由于采用以上结构改进,在叶轮进口处增加一轴向限流套,通过控制限流套的外径,从而控制限流套与叶轮进口之间的过水面积,达到调节进水量的目的,防止电泵过载运行,运行安全可靠。
附图说明
图1为本实用新型结构示意图。
具体实施方式
现结合附图所示实施例对本实用新型作出详细说明。
如图1所示,一种限流潜水电泵,包括现有的潜水电泵1,在潜水电泵叶轮2下面的传动轴3上装有限流套4。
