A Brief Introduction to Beam Pumping Unit

Beam pumping unit, also known as beam pumping unit, beam type crank balanced pumping unit, refers to a pumping unit with a floating beam, reversing through a connecting rod mechanism, and balanced by crank weights, commonly known as a kowtow unit. In terms of oil production method, it is a rod type oil extraction equipment (in terms of oil production method, oil extraction equipment can be divided into two types: rod type oil extraction equipment and rodless type oil extraction equipment).

The beam pumping unit is one of the main types of pumping units currently used in the oil field. According to beam pumping unit manufacturers, the pumping unit mainly consists of four parts: horsehead - beam - connecting rod - crank mechanism, reducer, power equipment and auxiliary equipment. The motor drive is converted into the up-and-down motion of the horsehead through the gearbox and the crank link mechanism in work, then the horsehead drives the plunger of the downhole oil pump up and down by the polish rod and the sucker rod to continuously pump crude oil out of the well.

Main characteristics of beam pumping unit:

1. The beam pumping unit manufacturers indicates that this machine has reasonable structure, stable work status, low noise, convenient operation and easy maintenance.

2. The beam adopts box or I-steel structure to obtain high strength, good rigidity and large bearing capacity.

3. The reducer adopts the herringbone involute or biarc tooth profile gear to realize the high processing precision, strong bearing capacity and long service lifetime.

4. The beam pumping unit manufacturers says the horsehead can be turned up, hung up or turned sideways.

5. The brake adopts the external-contacting structure and is equipped with safety device, which makes it flexible in operation, quick in braking, safe and reliable in performance.

6. The pedestal can be connected either by foundation bolts or pressure bars.
