Abstract

The invention relates to the technical field of beam-pumping units and discloses a digital automatic control oil pumping method and a mobile balancing digital oil pumping unit. The mobile balancing digital oil pumping unit comprises a main motor, a speed reducer, a crank, a connecting rod, a walking beam, a balance crane arm, a bracket, a mule head, a pedestal, a brake device, a beam hanger, a load sensor, a stroke process measurer, a safety limit device and a digital control cabinet. The mobile balancing digital oil pumping unit enables a mobile weight box to move horizontally on the balance crane arm, automatically balances polished rod load under different working conditions, automatically regulates the stroke times of the oil pumping unit according to the fullness change of a pump, is safe and reliable, facilitates operation, completely develops the oil well yield, improves the balance rate, and realizes energy saving and cost reducing.

Description

technical field [0001] The invention relates to the technical field of beam pumping units, and relates to a digitalized automatic control method for pumping oil and a moving balance digitalized pumping unit. Background technique [0002] The existing beam pumping units mainly include: conventional beam pumping unit, front beam pumping unit, offset beam pumping unit and special-shaped beam pumping unit, etc. The beam pumping unit generally includes a donkey head, a beam, a bracket, a connecting rod, a base, a crank, a balance device, a reducer, a brake, a motor and a rope hanger, and a bracket, a reducer, a brake, Motor and control cabinet, etc., the beam is hinged on the bracket, the crank is fixed on the output shaft of the reducer, one end of the connecting rod is hinged on the crank, and the other end of the connecting rod is hinged on the beam, thus forming a four-bar linkage Mechanism, the donkey head is installed on the front end of the beam, the rope hanger is instal...
