我矿选矿厂使用的6PS型砂泵进水室,采用代号为HT21-40的灰口铸铁材质,重量为325公斤,经十几道工艺加工制成,价值835元。砂泵在运转中,由于泥浆中砂石的冲击,进水室磨损很快,平均寿命只有三个月,往往备件供应不上。针对这种情况,我们把报废了的进水室拣回来,采用环氧树脂配方粘补砂泵进水室,重新用于生产。经过粘补的进水室,从1977年8月11日投产使用,至12月份还没有坏。 The 6PS sand pump inlet chamber used by our ore dressing plant is made of gray cast iron with code HT21-40 and weighs 325 kg. It is made of more than 10 pieces of process and is worth 835 yuan. Sand pump in operation, due to the impact of sand and mud in the mud, water chamber wear quickly, the average life expectancy of only three months, often spare parts supply is not on. In response to this situation, we scrapped the inlet chamber pick-up, the use of epoxy resin sticking sand pump inlet chamber, re-used in production. After sticky water chamber, from August 11, 1977 put into use, to December has not been bad.
