The beam-pumping unit is also called beam-pumping unit and beam-type crank balance pumping unit, and is called as kowtow machine. The beam pumping unit is one of the types of pumping units mainly used in oil fields at present, and mainly consists of four parts, namely a horsehead, a beam, a connecting rod, a crank mechanism, a reduction gearbox, power equipment and auxiliary equipment. When the oil pumping device works, the rotation of the motor is changed into the up-and-down motion of the horsehead through the gearbox and the crank connecting rod mechanism, and the horsehead drives the plunger of the underground oil pumping pump to do up-and-down motion through the polished rod and the sucker rod, so that crude oil in the well is continuously pumped out of the shaft.
The balance structure of the common beam pumping unit is as follows: the balance plate with a certain weight is arranged at the tail part of the walking beam, so that the walking beam is a simple balance mode and is suitable for light pumping units with the weight less than 3 tons. The crank is balanced, and the balance weight is arranged on the crank, so that the oil pumping machine is suitable for a heavy oil pumping machine. The composite balance uses the balance of the walking beam and the balance of the crank on a pumping unit at the same time. The pneumatic balance is realized, the energy is stored and released by utilizing the compressibility of the gas to achieve the purpose of balance, and the pneumatic balance can be used for heavy oil pumping units with the weight of more than 10 tons.
