近几年来,全国各油田大量采用往复式污水泵注水,但由于油田污水的腐蚀性较大,泵的腐蚀损坏十分严重,除了往复泵的液力端腐蚀损坏外,还有十字头滑道的腐蚀、磨损、拉伤,甚至粘住等现象。污水泵运行5000小时左右,十字头和滑道的配合间隙由原来0.08mm扩大到0.3～0.8mm,引起十字头的中心下降,造成十字头杆上套与浮动会内孔摩擦拉伤,油封偏磨、拉伤而失效,大量机油外漏,污水进入曲轴箱,最终导致十字头粘住和连杆烧瓦事故发生。这样,不仅增加水泵的运行费用,也影响了油田污水的回注,给油田开发造成很大的经济损失。为了解决3S3三柱塞泵的十字头滑道磨损,我们
In recent years, a large number of reciprocating sewage pumps have been used in various oil fields across the country. However, due to the corrosive nature of the oilfield wastewater, the corrosion of the pump is very serious. In addition to corrosion damage on the hydraulic end of the reciprocating pump, Corrosion, wear, strain, and even stuck phenomenon. Sewage pump operation for about 5000 hours, crosshead and slide with the gap from the original 0.08mm expanded to 0.3 ~ 0.8mm, causing the crosshead center down, resulting in the crosshead pole sleeve and the floating will friction friction, oil seal partial Wear and tear, failure, a large number of oil leakage, sewage into the crankcase, eventually leading to crosshead sticking and connecting rod burning tile accident occurred. In this way, not only increase the operating costs of the pump, but also affect the injection of oilfield sewage, causing great economic losses to the development of the oil field. In order to solve the 3S3 three-piston pump cross-head slide wear, we
