我矿1986年从石家庄水泵厂购进4台该厂从澳大利亚引进技术生产的3/2D-HH渣浆泵。该泵由于所选用的耐磨材质为硬镍1号,配件价格非常昂贵,仪一副前、后衬板的价格就高达1 400多元。在转速1137转/分、d_(50)=0.1毫米,C_w=20%的情况下使用,寿命仅为1个月。为了降低生产成本,我们采用橡胶衬板代替金属衬板的方法,并于1988年初与衡山沙泉橡胶厂共同研究生产出了第一批橡胶 I mine in 1986 from Shijiazhuang Pump Factory purchased 4 units from Australia to introduce technology to produce 3 / 2D-HH slurry pump. The pump due to the selection of wear-resistant material for the hard nickel 1, the price is very expensive accessories, a pair of instrument before and after the lining of the price up to more than 1,400 yuan. Used at a speed of 1137 rev / min, d_ (50) = 0.1 mm and C_w = 20%, the service life is only 1 month. In order to reduce production costs, we use rubber lining instead of metal lining method, and in early 1988 and Hengshan sand spring rubber factory jointly produced the first batch of rubber
