Description

Technical Field

[0001] The invention relates to the technical field of oil pumping units, and in particular to an adaptive balancing and regulating device for an oil pumping unit. Background Art

[0002] At present, conventional walking beam pumping units are still the main devices for oil field production operations, and their number accounts for more than half of the total number of pumping units. However, long-term exploitation of oil wells will lead to changes in formation conditions, causing the pumping units that were originally in a balanced state to operate in an unbalanced state. There are two main ways to balance and adjust the pumping units in service in domestic oil fields: one is to increase the walking beam counterweight of the pumping unit itself or move the crank balance block by manpower. This method is basically for the technicians to calculate the distance that the crank balance block needs to move or the number of walking beam balance blocks that need to be added, and then the operators perform high-intensity balance adjustment operations, which leads to low efficiency and poor safety of the balance adjustment, and the accuracy of the adjustment is largely affected by human subjective operation. Second, when the balance weight of the pumping unit itself can no longer continue to adjust the balance of the pumping unit, the balance adjustment device is installed on the pumping unit to continue to adjust it. According to research and analysis, most of the current balance adjustment devices are only implemented by installing mechanical components on the pumping unit. Contents of the invention

[0003] The purpose of the present invention is to overcome the existing technical defects and provide a self-adaptive balancing adjustment device for an oil pump.

[0004] The technical solution is: an adaptive balancing adjustment device for an oil pump, including a balancing beam, a base is arranged at the left end of the balancing beam, the base fixes the motor through a support rod, a detection control cabinet is arranged on one side of the motor, the detection control cabinet is connected to the motor connector through a cable, and the motor connector is arranged at the upper end of the motor; a screw rod parallel to the balancing beam is arranged on the upper part of the balancing beam, the right end of the screw rod is fixed to the balancing beam through a support plate, and the left end is fixed through a screw rod balancing base and a screw rod support rod, a communication cable is arranged inside the screw rod, and a balancing car is arranged on the screw rod.

[0005] Among them, the balancing car consists of a static plate, a traveling mechanism and a dynamic plate, the static plate is connected to the dynamic plate through a ball bearing, and the dynamic plate is provided with a traveling mechanism; one end of the screw balance base is connected to the motor, and the bottom thereof is provided with a screw support rod to fix the screw between the two; the control cabinet is provided with a power distribution speed regulation part and a data remote measurement and control part, the power distribution speed regulation part consists of a motor speed regulation unit and a motor switch unit, the motor speed regulation unit is connected to the motor switch unit, the data remote measurement and control part consists of a data acquisition device, a data transmission port and a control device, and the control device is respectively connected to the data acquisition device, the data transmission port, the motor speed regulation unit and the motor switch unit.

[0006] The present invention has the following beneficial effects:

[0007] (1) The balancing car installed on the self-balancing machine adopts a double-sided circular ring structure, which has a simple structure and is better at rotating than moving with a sliding block, and is not prone to getting stuck during use.

[0008] (2) Remote automatic control is adopted to automatically adjust the balancing stroke frequency. The balancing and stroke frequency adjustment saves time and effort, greatly reduces the labor intensity of front-line employees, improves the working environment of employees, and improves work efficiency.

DETAILED DESCRIPTION

[0014] like Figure 1 As shown, an adaptive balancing adjustment device for an oil pump comprises a balancing beam 1, a base 2 is arranged at the left end of the balancing beam 1, the base 2 fixes a motor 4 through a support rod 3, a detection control cabinet 5 is arranged on one side of the motor 4, the detection control cabinet 5 is connected to a motor connector 7 through a cable 6, and the motor connector 7 is arranged at the upper end of the motor 4; a screw rod 10 parallel to the balancing beam 1 is arranged on the upper part of the balancing beam 1, the right end of the screw rod 10 is fixed to the balancing beam 1 through a support plate 11, and the left end thereof is fixed through a screw rod balancing base 8 and a screw rod support rod 9, a communication cable is arranged inside the screw rod, and a balancing vehicle is arranged on the screw rod.

[0015] The balancing vehicle comprises a static plate 13 , a traveling mechanism 14 and a moving plate 15 . The static plate 13 is connected to the moving plate 15 via balls, and the moving plate 15 is provided with the traveling mechanism 14 .

[0016] One end of the screw balancing base 8 is connected to the motor 4, and the bottom thereof is provided with a screw support rod 9 to fix the screw 10 between the two.

[0017] like Figure 2 As shown, the control cabinet 5 is provided with a power distribution speed regulation part 16 and a data remote measurement and control part 17. The power distribution speed regulation part 16 is composed of a motor speed regulation unit 18 and a motor switch unit 19. The motor speed regulation unit 18 is connected to the motor switch unit 19. The data remote measurement and control part 17 is composed of a data acquisition device 21, a data transmission port 22 and a control device 20. The control device 20 is respectively connected to the data acquisition device 21, the data transmission port 22, the motor speed regulation unit 18 and the motor switch unit 19.

[0018] The present invention is based on the principle of moment balance. A suitable counterweight is added to the walking beam of the walking beam pumping unit. The actuator drives the counterweight to move on the walking beam. The balance of the pumping unit is improved by changing the position of the counterweight on the walking beam. In terms of intelligent control, the detection control cabinet is combined to perform automatic balance diagnosis and balance adjustment control. Therefore, the entire device design is divided into two parts: mechanical system design and intelligent system design. When working, the self-balancing intelligent pumping unit converts the rotational motion of the motor 4 into the up and down reciprocating motion of the sucker rod column. In addition, it automatically detects and displays the balance status and stroke frequency of the pumping unit in real time. According to the changes in the well conditions, the pumping unit can be automatically adjusted to the best balance status and the best stroke frequency.
