Description

Oil pumping machine posture regulating and controlling equipment

Technical Field

The utility model relates to a regulating device, in particular to a device for regulating and controlling the posture of an oil pumping unit.

Background

The beam-pumping unit is one of the main types of pumping units used in oil field, and is a pumping unit containing beam, reversing by link mechanism and balancing crank weight, and is mainly composed of four parts of horse head-beam-link-crank mechanism, speed reducer, power equipment and auxiliary equipment. The beam-pumping unit has a whole structure similar to a balance, one end is used for pumping oil load, and the other end is used for balancing and balancing the weight load. If the torque formed by the oil pumping load and the balance weight load is equal or consistent, the pumping unit can work continuously with little power.

When the pumping unit works, the transmission of the motor is changed into the up-and-down movement of the mule head through the reduction gearbox and the crank link mechanism, and the mule head drives the plunger of the down-hole oil pump to move up and down through the polish rod and the oil pumping rod, so that crude oil in the well is continuously pumped out of the shaft. The oil pumping load is balanced by increasing the counterweight of the oil beam and the length of the rear arm of the walking beam, so that the effects of saving energy and improving the load capacity of the oil pumping unit are achieved.

The balance weight of the existing pumping unit is fixed during operation, the load of the oil well changes, the height of liquid in the well continuously rises along with the pumping, and the back pressure of the well head increases, so that the pumping resistance of the pumping unit is inconvenient to increase, and the original balance state of the pumping unit can be damaged. If the balance weight needs to be adjusted, the machine is stopped, and the balance weight is increased manually. The pumping unit only provided with the fixed balance weight during operation is a substantial breakthrough that the balance of the pumping unit cannot be realized, cannot meet the current energy-saving operation requirement, and cannot adapt to the increasingly developed requirements of the current science and technology. On the other hand, the oil extraction loads of different oil wells are different, and the oil extraction loads of the same oil well are different along with the gradual reduction of the oil quantity, so that the oil pumping unit is poor in balance effect and still large in energy consumption.
