高速往复泵阀弹簧的腐蚀疲劳断裂是影响泵正常运行的主要因素。本文对油田注水用的六柱塞高速高压往复泵阀弹簧进行了试验。实践证明,3J_1材料在高冲次及清水等介质的泵上制作阀弹簧是合适的。它具有耐疲劳、耐腐蚀等特点,解决了断裂问题。在每分钟980次高频率和清水介质中使用已超过4000小时,并仍在继续使用中(原只能用100小时左右)。图2,表4,参考文献2。 High-speed reciprocating valve spring corrosion fatigue fracture is the main factor affecting the normal operation of the pump. In this paper, six-plunger high speed and high pressure reciprocating valve spring for oilfield water injection was tested. Practice has proved that 3J_1 material in the high-rushed and clear medium water pump valve spring is suitable. It has fatigue resistance, corrosion resistance and other characteristics, to solve the problem of fracture. It has been used for more than 4,000 hours at 980 high frequency and clear media every minute and is still in use (it only lasts for about 100 hours). Figure 2, Table 4, Reference 2.
