我们参考本省《化工技术情报》第十期刊登的反叶轮泵的结构形式,与车间技术员、维修组工人师傅一道,对现有某些水泵进行改革试验。经分析水泵的工作原理,认为只需将叶轮与泵壳作相应的改制即可,其余另件不必更动。资料图纸泵壳上需要一个凸肩与叶轮槽相配,而原泵壳无法加工出,于是我们在泵壳上车一台阶孔,锒一环形另件代替凸肩,具体尺寸附图于后面。 We refer to the province’s “Chemical Technology Information” published in the tenth issue of anti-vane pump structure, with the workshop technicians, maintenance workers, a master team to conduct some of the existing pump reform test. The analysis of the working principle of the pump, that only the impeller and the pump casing can be adapted accordingly, the other parts do not have to change. Drawings on the pump housing data need a shoulder and impeller slot match, and the original pump shell can not be processed, so we have a hole in the pump casing, 锒 a ring-shaped pieces instead of shoulders, the specific size of the drawings in the back.
