Indirectly driven traction type pumping unit

Abstract

The invention discloses an indirectly driven traction type pumping unit, which radically solves the problems of limited traction force, limited application environment and the like of the conventional traction type pumping unit. The pumping unit comprises a frame, a base, a hanging device and a traction device. The pumping unit is characterized in that: upper and lower motor seats for fixing a permanent magnet synchronous motor are respectively arranged on the frame and the base; a traction wheel of the traction device is assembled together with a rotor on a driving main shaft of the permanent magnet synchronous motor, and a coder is arranged at the end of the main shaft of the permanent magnet synchronous motor; drum-type gate arms are arranged on two sides of a brake wheel and connected with electromagnetic brakes on the upper part of the permanent magnet synchronous motor; left and right traction steel wire ropes are respectively wound on the same traction wheel in the same direction, and one end of each of the steel wire ropes goes around a lower pulley block and is fixed on the base; and the other ends of the steel wire ropes respectively go around a guide wheel and two upper pulley blocks fixed on the frame and are fixed on the frame. Compared with similar products, the pumping unit has the advantages of reasonable design, low cost, safety and reliability in operation, large traction force, high transmission efficiency and wide application range.

Description

technical field [0001] The invention relates to a traction type oil pumping unit, in particular to an indirect drive traction type oil pumping unit which is suitable for low-lying areas where water often accumulates or shallow sea areas, and for areas with strong winds and frequent maintenance. It can replace large oil beam machines of type 20 or above, and belongs to the technical field of oil field production machinery. Background technique [0002] At present, most of the pumping units used in my country's oilfields are beam pumping units, which have a relatively simple structure, durability, and convenient maintenance and operation, but have low transmission efficiency, high energy consumption, many consumables, and intelligence. low-level defects. In order to overcome the above shortcomings and respond to the national call for energy conservation and emission reduction, people pay more and more attention to traction pumping units, and heavy traction pumping units are mo...
