Beam-pumping unit based on direct drive motor

Abstract

The invention discloses a beam-pumping unit based on a direct drive motor. The beam-pumping unit comprises a base, wherein a bracket is arranged at the upper end of the base, a walking beam is arranged at the upper end of the bracket, a mule head is arranged on one side of the walking beam, a lifting rope is arranged on the mule head, a rope suspender is arranged on the lifting rope, and a balancing block is arranged at one end, far from the mule head, of the walking beam; and a support seat is further arranged at the upper end of the base, and the direct drive motor is arranged at the upper end of the support seat. According to the beam-pumping unit based on the direct drive motor, the combined use of a belt, belt wheels and a speed reducer of a traditional pumping unit is canceled, so that the fault probability of the pumping unit is greatly decreased, additional maintenance and repair are omitted, the use cost is lowered, and the production efficiency is improved; and the power consumption of the pumping unit driven by the direct drive motor is relatively low, the current and the voltage can be regulated according to the working state of the pumping unit, the output power of the motor can be automatically regulated, and the energy conservation effect reaches 20% or above.

Description

technical field [0001] The invention relates to the technical field of pumping units, in particular to a beam pumping unit based on a direct drive motor. Background technique [0002] 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. The traditional beam pumping unit requires the cooperation of the motor and the reducer to provide power, but the reducer needs to replace the lubricating oil and the transmission belt regularly. Both the reducer and the transmission belt will increase the failure rate, and the motor power required by the traditional pumping unit Very high, the output power of the motor changes little, which increases a lot of production costs and is not energy-saving enough. Contents of the invention [0003] The object of the present invention is to propose a beam pumping unit based on a direct drive motor in order to solve the shortcomings in the prior ...
