Example Embodiment

[0018] Figure 1 shows an embodiment of the double-disc motor-driven pumping unit of the present invention. A double-disc motor-driven pumping unit includes a frame 1, a walking beam 2 arranged on the frame 1, and a donkey head 3 arranged at one end of the walking beam 2. The other end of the walking beam 2 is usually provided with a The weight 14, the pump rod 4 arranged under the donkey head 3 and connected to the donkey head 3, is arranged on the connecting rod 5 on the other side of the walking beam 2, and a double disc motor 6 is arranged under the connecting rod 5, and the double disc motor 6 The disk surfaces on both sides of the disk are symmetrically provided with supporting shafts 7 and two connecting rods 5 respectively hingedly connected, and the upper ends of the two connecting rods 5 are hingedly connected to the walking beam 2 respectively;

[0019] As shown in Figures 1 and 2, a double-disc motor 6 includes a base 8, a main shaft 9 arranged on the base 8, two disc s...

Abstract

This invention discloses a dual-disk motor driven oil pumping machine including a rack, a free beam set on the rack, a donkey head set on a side of the beam, a pump rod set on the donkey head and a connection rod on the other side of the beam, a dual-disk motor is set under the rod, supporting shafts set symmetrically at both sides of the motor are hinged with the two connection rods and the top ends of the rods are hinged with the free beam. Advantages: connection-rod drive is applied directly and gear speed-reduction unit is not used so the mechanical structure of an oil-pumping machine is simplified and efficiency is increased.

Description

technical field [0001] The invention belongs to an oil pumping device for exploiting oil from an oil well. Background technique [0002] Traditional pumping units generally adopt a beam-type structure, one end of which is connected to the oil well pump, and the other end is reciprocated by a driving motor through a complex gear reduction mechanism. Because the rotational speed of the beam of the pumping unit is very slow compared with the rotational speed of an ordinary motor, when an ordinary rotating electrical machine is selected for driving, the structure of the high-torque gear reduction box is very large and complicated. This deceleration mode adopting a large speed ratio reduces the overall working efficiency of the pumping unit. The complex mechanical structure reduces the reliability of the whole machine and increases the maintenance cost of the equipment. Furthermore, the pumping unit is the basic equipment of the oil field, and the consumption is very large, and...
