Energy-saving pumping unit with two horse heads

Abstract

The invention provides an energy-saving pumping unit with two horse heads. The energy-saving pumping unit with the two horse heads comprises a base, a support, a walking beam, the front horse head, the rear horse head and a speed controller, wherein the support is fixedly arranged on the base, the walking beam is arranged on the top of the support, one end of the walking beam is connected with the front horse head, a wind power generation device is arranged on the top of the walking beam and is connected with a second motor through a PLC, an adjustment hole is formed in the middle of the walking beam, the adjustment hole is connected with a balance block through an adjustment rod, and the balance block is connected with the second motor. According to the energy-saving pumping unit with the two horse heads, the adjustment hole is connected with the balance block through the adjustment rod, the balance block is connected with the second motor, and thus the stability of the pumping unit is improved; the second motor is connected with the wind power generation device, and thus production cost is reduced. The energy-saving pumping unit with the two horse heads has the advantages that the oil production efficiency is high, the fatigue loss of the pumping unit is reduced, the mechanical efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the field of pumping units, in particular to an energy-saving double donkey head pumping unit. Background technique [0002] The pumping unit is an essential equipment in oil extraction. Generally, each crude oil production well uses at least one pumping unit to pump out the oil deeply hidden in the ground through the oil extraction pipe. When the pumping unit is pumping oil, the up and down strokes are different. During the up stroke, the oil is subjected to the viscous resistance of the oil, the gravity of the oil, and the gravity of the sucker rod. At this time, the motor does useful work, but the down stroke, It is affected by the resistance of the oil. Due to the obvious weight of the sucker rod, the motor does a lot of useless work, and the actual descending speed is not as fast as the actual rising speed. The fatigue consumption of the pull rod that squeezes the sucker rod will increase significantly, and pumping stops ...

Problems solved by technology

When the pumping unit is pumping oil, the up and down strokes are different. During the up stroke, the oil is subjected to the viscous resistance of the oil, the gravity of the oil, and the gravity of the sucker rod. At this time, the motor does useful work, but the down stroke, It is affected by the resistance of the oil. Due to the obvious weight of the sucker rod, the motor does a lot of useless work, and the actual descending speed is not as fast as the actual rising speed. The fatigue consumption of the pull rod that squeezes the sucker rod will increase significantly, and pumping stops often due to broken belts phenomenon, increased production costs
