摘要
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。
By reinforcing the back of the rubber cup with cord fabric and increasing the diameter of the thrust plate, the service life of drill pump pistons Can be increased greatly, Field tests show that the piston life has reached 118 hours at 30 MPa pump pressure, and 450 hours at 20 MPa.
