通过小型泵50D的模拟试验研究,比较了易损件平衡环材质ZQAL9—4、HT20—40,含钛合金灰铸铁的耐磨性能和耐磨蚀性能,提出了以含钛灰铸铁代替ZQAL9—4平衡环,材料成本可减至原来的九分之一,经大庆采油厂125D输油泵和鹤岗南山矿5DA8排水泵生产试验,耐磨寿命可提高至原来铜合金的7倍以上,为清水泵易损件材质开辟了新途径,可以在D型、DA型清水泵及中低压锅炉给水泵中推广应用。 Through the simulation test of the small pump 50D, the wear resistance and abrasion resistance of ZQAL9-4, HT20-40 and titanium alloy gray cast iron with wearing parts were compared. The titanium gray cast iron instead of ZQAL9- 4 balance ring, the material cost can be reduced to 1/9 of the original. After production test of 125D oil pump of Daqing Oil Production Plant and 5DA8 drainage pump of Nanshan Mine of Hegang, the wear life can be increased to more than 7 times that of the original copper alloy, Pump consumables material opened up a new way, you can D-type, DA-type pumps and low pressure boiler feed pump in the promotion and application.
