Abstract

The present invention provides a balance adjustment device and a beam pumping unit with the same. The balance adjustment device includes: a first counterweight part, the first counterweight part includes a first base body and a The first liquid storage tank, the first seat body is used to be arranged on the counterweight beam of the beam pumping unit; the second counterweight part, the second counterweight part includes the second seat body and is arranged on the second seat body The second liquid storage tank, the second seat body is used to be arranged on the beam of the beam pumping unit; the pumping part, the first liquid storage tank and the second liquid storage tank are all connected with the pumping part, pumping The portion is capable of delivering liquid from the first storage tank to the second storage tank, and delivering liquid from the second storage tank to the first storage tank. Through the technical solution provided by the invention, the problem of inconvenient balance adjustment of the beam pumping unit in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of beam pumping units, in particular to a balance adjustment device and a beam pumping unit with the same. Background technique [0002] The beam pumping unit is the main oil extraction equipment in our country. It has the advantages of simple structure, reliability and durability, and is widely used in major oil fields. At the same time, due to its structural characteristics, when the beam pumping unit operates in an unbalanced state, there are problems such as huge energy loss and reverse power generation. The key to solving the problem is the adjustment of the balance of the beam pumping unit. At present, there are many ways to adjust the balance; the first is to adjust the balance of the crank, that is, to change the quality of the crank balance weight, or to change the distance between the balance weight and the crank rotation center to achieve balance adjustment. This method is difficult to operate i...
