长期以来,砂泵衬里因耐磨过不了关而成为使用单位的老大难问题。1972年以来,我们在各级党组织的领导下组成三结合试验小组,先后在通化矿务局铁厂洗煤厂和湾沟洗煤厂、通化铜矿、云南锡业公司大屯选矿厂等单位采用各种类型的铸石作5PS 和6SP 型砂泵衬里试验,经过一段时间运转试验,已取得可喜的成果,铸石衬里的砂泵寿命一般比普通铸铁泵提高5～6倍或7～8倍。其后又在本钢歪头山铁
For a long time, the sand pump lining can not pass the wear-resistant off and become the most difficult problem to use the unit. Since 1972, we have formed a three-in-one experimental group under the leadership of party organizations at all levels. We have successively adopted such measures as the ironworks coal washing plant of Tonghua Mining Administration and the coal washing plant of Tonggou Coal Preparation Plant, Tonghua Copper Mine and Yunnan Tin Company Datun Ore Concentration Plant Various types of cast stone for 5PS and 6SP sand pump lining test, after a period of time running test, has achieved gratifying results, the cast-lined sand pump life is generally increased by 5 to 6 times than ordinary cast iron pump or 7 to 8 times. Then Benxi Iron and Steel tilted head iron
