我矿选矿厂磨矿系统2台8英寸砂泵(其中1台备用)是选矿厂中的主要设备之一,直接影响磨矿系统的正常运行。1970年投产使用的是从瑞典引进的VASA459-8英寸砂泵。使用不到2年,衬胶备件得不到解决,限于当时的条件,我们首次对8英寸砂泵进行改进,即衬胶泵改为铸铁壳砂壳。改进后的这种砂泵十分笨重,泵壳磨损严重,检修劳动强度大,备件消耗大。不仅影响了生产,而且因换泵放砂频繁造成大量金属流失。为此,1978年3月与上海衬胶泵攻关组合作,参照瑞典砂泵,取长补短进行设计,试制成功125FJ-27型砂泵。使用这种自制砂泵,不仅每年可
I ore dressing plant grinding system 2 8-inch sand pump (of which 1 spare) is one of the major equipment in the concentrator, a direct impact on the normal operation of the grinding system. Put into operation in 1970 is the VASA 459-8 inch sand pump imported from Sweden. Less than 2 years, rubber lining spare parts can not be resolved, limited to the conditions at the time, we first for the 8-inch sand pump to improve, that is rubber-lined pump to cast iron shell sand shell. Improved sand pump is very heavy, serious pump casing wear, labor-intensive maintenance, spare parts consumption. Not only affect the production, but also because of frequent replacement of the pump put sand caused a lot of metal loss. To this end, in March 1978 and Shanghai rubber lined pump research team, with reference to the Swedish sand pump, learn from each other to design, trial success 125FJ-27 sand pump. Use this homemade sand pump, not only every year
