我队在鑽探工程中,因矿区水源困难,曾使用矿湖水进行鑽井內供水。但由于該水含酸性很强,对水泵缸套和橡皮圈腐蝕很厉害,因而橡皮圈消耗过多,影响工作。据此,我們研究利用罗旋盤根代替橡皮圈,经試驗效果良好。其代替方法是:在100/30型水泵中,应將活塞垫改动一下,原活塞垫槽是梯形现 In our drilling project, my team used mine water to supply drilling water due to the difficulty of water source in the mine area. However, due to the strong acidity of the water, the pump cylinder sleeve and rubber ring corrosion is very powerful, so the rubber band consume too much, affecting work. Based on this, we study the use of Rotary screw instead of a rubber band, the test results are good. The alternative method is: 100/30 type pump, the piston pad should be changed about the original piston pad groove is trapezoidal
