Novel mechatronical low load oil pumping machine

Abstract

The invention belongs to the field of oil field extraction equipment, and particularly relates to a novel mechatronical low load oil pumping machine. A rotating shaft of the motor is connected with a belt pulley; the belt pulley and a driving wheel are respectively connected with a reducing motor, and are respectively positioned at the two ends of the reducing motor; the driving wheel and a driven wheel are connected through a rope; the driven wheel is connected with a first guide wheel through the rope; the first guide wheel is connected with a fixed pulley through the rope; the fixed pulley is connected with a second guide wheel through the rope; the second guide wheel is connected with a pumping rod through the rope. The novel mechatronical low load oil pumping machine has the benefits that a walking beam and a suspension beam are not needed to be driven to act by the motor, the overall structure of the machine is simple, the mass is reduced, so that the load of the motor is reduced, the energy consumption is less, the oil pumping efficiency is high, and the requirements of energy conservation and consumption reduction development are met.

Description

technical field [0001] The invention belongs to the field of electromechanical integration equipment, and in particular relates to a novel electromechanical integration low-load pumping unit. Background technique [0002] With the continuous progress of society, the human demand for oil is also increasing, and the exploitation of oil is becoming more and more frequent. Generally, the equipment we use to extract oil is the pumping unit. Pumping unit is a kind of machinery and equipment for oil extraction, commonly known as "kowtow machine", which makes oil out of the well by pressurizing. At present, the pumping units in service in oil fields are mainly beam pumping units. The overall action of the pumping unit is mainly to rely on the interaction between the beam and the suspension beam to achieve oil pumping.

Problems solved by technology

At present, the pumping units in service in oil fields are mainly beam pumping units. The overall action of the pumping unit is mainly to rely on the interaction between the beam and the suspension beam to achieve oil pumping. When the suspension point load of the pumping unit is between the upper and lower When the stroke changes greatly, the net torque of the crankshaft of the reducer will appear negative, and the gear of the reducer is vulnerable to "back impact", which increases the working load of the motor and the reducer, and consumes a lot of energy. Reduced service life of the reducer

The pumping unit drives the crank through the motor and the reducer, and the connecting rod drives the beam, the donkey head, the braid, and the sucker rod to work. The whole machine is heavy, the motor load fluctuates greatly, and the power consumption is large, so it cannot adapt to energy saving and consumption reduction. development needs
