增强型钻井泵活塞采用帘布加强根部和加大压板尺寸,使活塞使用寿命大大提高。现场试验表明,泵压30MPa时使用寿命达118h,20MPa时为450h以上,比国产常规活塞高3倍多。
Enhanced drilling pump piston with a cord to strengthen the roots and increase the size of the platen, the piston life greatly improved. Field tests showed that the pump life of 30MPa up to 118h, 20MPa when more than 450h, more than three times the domestic conventional piston.
