我队1972年即开始使用国产BW250/50泥浆泵,初期用于清水钻进比较正常,1975年后用于泥浆钻进,效果较差:陶瓷柱塞和密封圈磨损快;泵头泥浆顺着住塞导杆、曲轴箱体上的骨架式橡胶油封和十字头室流进曲轴箱,使十字头、连杆瓦、连杆小头铜套等零件都过早磨损.虽然后来在陶瓷柱塞后加了一个橡皮档,但收效不大,仍不能杜绝泥浆窜入曲轴箱.为了进一步解决上述问题,我们广泛收集钻工同志们的意见,在泵头和曲轴箱间增加了一个防砂装置(见附图).经过一年的改装试用,泵压泵量均正常,泥浆窜入曲轴箱的情况大为减少.过去是每个星期就要检修一次,现在一般是1～2个月检修一次.有一台泵,使用了三个月,只更换了一次机油就保证正常运转.
Our team started to use homemade BW250 / 50 mud pump in 1972, which was used for normal water drilling more normally. After 1975, it was used for mud drilling with poor effect: the ceramic plunger and the seal ring wear fast; Plug guide rod, the crankcase body skeleton rubber seal and crosshead chamber into the crankcase, crosshead, connecting rod watts, connecting rod small brass parts and other parts are premature wear.Although later in the ceramic plunger After adding a rubber gear, but with little success, still can not stop the mud fleeing into the crankcase.In order to further solve the above problems, we widely collect the comrades of drilling comrades, in the pump head and crankcase added a sand control device ( See the photo.) After a year of trial conversion, the pump pressure is normal, mud fleeing into the crankcase greatly reduced the situation is the past once a week to be overhaul, and now is generally 1 to 2 months overhaul There is a pump, which has been in use for three months, ensuring normal operation with just one change of oil.
