Balance type intelligent pumping unit

Abstract

The invention relates to a balance type intelligent pumping unit. A pumping unit walking beam is installed on a pumping unit support, a pumping unit horse head is installed at the right end of the pumping unit walking beam, and an intelligent balance weight adjusting device is installed at the left end of the pumping unit walking beam. An inner supporting plate is fixed to a plate below a box, a plate above the box, the plate below the box and side plates are welded into a box shape, a mandrel is connected to a movable nut and placed into the box, inner bearings and a spacer sleeve are arranged on the mandrel in a sleeved mode, a balance weight is arranged on the mandrel in a sleeved mode, and a box tail plate is connected at the tail of the plate above the box and the plate below the box; a threaded rod is in screw thread fit with threads of the movable nut, an output shaft of a power driving device is connected with the threaded rod and then fixed to the box tail plate, and under the control of an intelligent system, the power driving device drives the movable nut to move and drive the balance weight to move, so that the balance weight gets away from or close to the pumping unit support, load balance between the pumping unit support and the pumping unit horse head is achieved, and the pumping unit works in the optimal balance state. The problem that at present balance of the pumping unit is difficult to adjust is solved, and the mechanical efficiency of a pumping system can be greatly improved.

Description

technical field [0001] The invention relates to a pumping unit used in an oil field, in particular to a balance type intelligent pumping unit. Background technique [0002] The balance of the pumping unit needs to be adjusted frequently to ensure that the pumping unit works in the best balanced state, so as to achieve the purpose of improving mechanical efficiency. The current method of adjusting the balance of the pumping unit is to manually disassemble the bolt group connecting the balance object after the pumping unit is stopped, and then move the balance object to keep the pumping unit in a certain balance in the up and down strokes. , It is very slow and laborious to disassemble, and the operators are dangerous, which is easy to cause personal injury. The pumping unit has a long downtime, which delays production and affects oil well production. Due to these problems, the pumping unit is not adjusted even if there is an unbalanced problem when it is working (even if it ...

Problems solved by technology

The current method of adjusting the balance of the pumping unit is to manually disassemble the bolt group connecting the balance object after the pumping unit is stopped, and then move the balance object to keep the pumping unit in a certain balance in the up and down strokes. , It is very slow and laborious to disassemble, the operator is dangerous, and it is easy to cause personal injury. The pumping unit has a long downtime, which delays production and affects oil well production.

Due to these problems, the pumping unit is not adjusted even if there is an unbalanced problem when it is working (even if it is adjusted, it cannot be adjusted immediately, and it cannot be adjusted to a relatively balanced state), resulting in the pumping unit not being in the best balance. working under low conditions, the working condition of the pumping unit is poor, the power consumption is large, the work is not stable, the noise is large, and the service life is short
