First, what is the working principle of beam pumping unit
Its working principle is that the rotation of the motor through the gearbox and the crank connecting rod mechanism becomes the up and down movement of the donkey head, and the plunger of the pump is driven up and down by the smooth rod and the sucker rod, so that the crude oil in the well is constantly extracted from the wellbore.

Second, what are the characteristics of the beam pumping unit
The beam pumping unit has the characteristics of reliable performance, simple structure, convenient operation and maintenance. Its main features are:
1, the machine structure is reasonable, stable work, low noise, easy operation and maintenance.
2, travel beam selection box type or I-beam structure, high strength, good rigidity, large bearing capacity.
3, the reducer adopts herringbone involute or double circular arc tooth gear, high machining accuracy, strong bearing capacity, long service life.
4, the donkey head can be used in one of the three forms of upturning, hanging or side turning.
5, the brake adopts external holding structure, equipped with safety device, flexible operation, rapid braking, safe and reliable.
6, the base adopts one of two ways of anchor bolt connection or pressure bar connection.
