AI Technical Summary
The current pumping unit's stroke rate is difficult to adjust flexibly, causing it to continue operating at high speed even when the produced fluid is declining, resulting in component wear and increased operating costs.
By adjusting the diameters of the large and small pulleys, and utilizing the rotating and mounting components, the pumping unit's stroke rate can be flexibly adjusted. After the motor starts, there is no need to change the speed; the belt running speed is adjusted by changing the pulley diameter.
This allows for flexible adjustment of the pumping unit's stroke rate based on actual production conditions, reducing component wear and operating costs, and enhancing the practical value of the equipment.
