改良创新提升泵效率的报告
——宙斯泵业如何提升塑料离心泵效率、节能8~20%的过程

  宙斯泵业是生产衬塑型、全塑型防腐离心泵的专业生产厂家,年生产防腐泵3万台左右。公司生产的塑料离心泵、清液泵,在国内在岗位运行的数量有几十万台,但一直与其它防腐塑料泵一样,存在着泵效率不高的问题。相同规格、相同性能参数前提下的塑料泵与金属泵相比较,一般泵效率要低5~15%左右,电能要多消耗10~25%左右。塑料离心泵效率低已成为目前市场的共识。但因为塑料离心泵有优良的防腐性能、较好的耐磨性能(超高分子量聚乙烯)、价格经济等因素,还是被人们所接受。再则也无其它更优良的泵种可选,只能被迫选用这种效率不佳的衬塑型、全塑型防腐泵。

  以宙斯泵业本公司为例,最近三年配套销售电机115万千瓦左右时,假设所销售泵平均每年每台运行100天,节电15%(保守估计)计算,节约的电能为:115万千瓦×100天×24小时×15%=4.14亿度电(千瓦时),按每度电1元计算,就会为用户节约4.14亿元/年。该数据仅为宙斯泵业三年内销售的泵,还不包括用户自备电机在内,为用户使用成本的节省十分明显。因此,通过技术创新,提升塑料泵的效率是迫在眉睫的,同时它也成为宙斯泵业近年来的战略目标。

  针对这一因素的解决方法难以寻求,因为塑料的热变形性、膨胀性、可塑性无法改变。但是经多次改良、试验,发现在泵盖与叶轮口环设置V型返流斜面(专利<申请>号:201621271230.2),使泵腔中高压区向泵吸入口返流的流体,向泵吸入口顺向返流,由原来反流流体与泵吸入口流体的流向呈90°角,改良为45°角以内,使返流流体对吸入口流体的作用的逆向冲击转化为顺向助推,通过改进后相对减少了流体的流阻,增加了吸入口流体的推力,提升了泵的效率。经试验,该项技术可以使塑料离心泵提升0.5~1%的效率。
