往复泵在石油工业中应用广泛。钻井时,利用它把泥浆泵入井内进行循环;采油时,利用它进行压裂、注水等工作;石油输送,也往往采用它把原油由一地输送到另一地。所以,往复泵是石油矿场最通用和最关键的设备之一。在矿场,由于用途不同,对往复泵的要求也不同。钻井时,希望泵具有高泵压,大排量,以适应快速钻井的需要;压裂时,不仅需要高泵压(有的达1000个大气压以上),由于
Reciprocating pumps are widely used in the oil industry. When drilling, it is used to pump the mud into the well for circulation. When it is used for oil production, it is used for fracturing and water injection. Petroleum transportation is also often used to transport crude oil from one place to another. Therefore, reciprocating pumps are one of the most versatile and critical equipment in the oil field. In the mine, due to different uses, the reciprocating pump requirements are also different. When drilling, it is hoped that the pump has high pumping pressure and large displacement so as to meet the needs of rapid drilling. When fracturing, not only high pumping pressure (some above 1000 atm) is required,
