Description

Technical Field

[0001] The utility model relates to the technical field of oil pumping units, in particular to an oil pumping unit. Background Art

[0002] A beam pumping unit, also known as a beam pumping unit or a beam crank balanced pumping unit, refers to a pumping unit that contains a walking beam, which is switched through a connecting rod mechanism and balanced by a crank weight. It is commonly known as a kowtow machine. When working, the rotation of the motor is converted into the up and down movement of the donkey head through the gearbox and the crank-connecting rod mechanism. The donkey head drives the plunger of the downhole oil pump to move up and down through the bare rod and the sucker rod, thereby continuously pumping the crude oil in the well out of the wellbore.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using the entire oil pump, it is necessary to install belts on the driving machine and the gear box for transmission. Since most oil wells lack protective mechanisms and most oil pumps are installed outdoors, in actual use, it is very likely that particles will be stuck between the belt and the driving machine and the gear box. Therefore, an oil pump is proposed to address the above problems. Utility Model Content
