【Abstract】 A new trailer mounted pumping unit consists of Benz chassis and oil-pumping machine. Through a hydraulic system, a power takeoff delivers power from truck engine to an oil pump for oil-pumping operation. Using in oil fields indicates that this new type of trailer mounted pumping unit has many good qualities comparing with others. For example, its engine power is very powerful; its oil pump is more efficient than others and has a function of self-protection; an apparatus that seals the steel cable is very useful and has a long life; the beam can move in three directions to centerize the oil well.更多还原
