Walking beam type oil pump additionally provided with speed increaser to adjust jig frequency

Abstract

The invention relates to a walking beam type oil pump additionally provided with a speed increaser to adjust the jig frequency. The left side of a base is connected with a bracket, the right side of the base is connected with a reduction gearbox, the speed increaser and a motor, the top of the bracket is connected with a central bearing assembly, the central bearing assembly is connected with a walking beam, the left end of the walking beam is connected with a horsehead, and the right side of the walking beam is connected with a bearing; the lower end of the bearing is connected with a connecting rod, an output belt pulley is connected with a small belt, the other end of the small belt is connected with the input belt pulley, the speed increaser is connected with the output belt pulley, and the output belt pulley is connected with a large belt; the other end of the large belt is connected with a large belt pulley, the large belt pulley is connected with an input shaft of the reductiongearbox, and an output shaft of the reduction gearbox is connected with a crank which is connected with the connecting rod; the motor drives the small belt, the small belt drives the input belt pulley, the speed increaser drives the output belt pulley, the output belt pulley drives the large belt, the large belt drives the large belt pulley, the large belt pulley drives the input shaft, the outputshaft drives the crank, the crank drives the connecting rod, and the connecting rod drives the walking beam to drive the horsehead to move up and down. The technology can meet different jig frequencyadjustment requirements and has an obvious power saving effect.

Description

technical field [0001] The invention relates to oil pumping equipment in the petroleum industry, in particular to a beam pumping unit for adjusting stroke times by adding a speed increaser. Background technique [0002] Known oil pumping equipment, especially beam pumping units account for more than 90% of all kinds of oil pumping units in oil extraction, but this oil pumping equipment has a large motor installed power, high starting current, large energy consumption, and oil pumping equipment. Difficulty in stroke adjustment and other defects. Most other improved pumping units use frequency conversion speed regulation or double reducers to adjust the stroke frequency. The defects are similar to the above-mentioned pumping equipment. So far, there is no new technology to break through this problem. Contents of the invention [0003] The invention provides a speed increaser with significant energy-saving effect by adding a speed increaser to adjust the stroke frequency of t...

Problems solved by technology

[0002] Known oil pumping equipment, especially the beam pumping unit accounts for more than 90% of all kinds of oil pumping units in oil extraction, but this oil pumping equipment has a large motor installed power, high starting current, large energy consumption, and oil pumping equipment. Difficulty in adjusting the number of strokes. Other improved pumping units mostly use variable frequency speed regulation or double reducers to adjust the number of strokes. The defects are similar to those of the above-mentioned pumping equipment. So far there is no new technology to break through this problem.
