Abstract

The utility model is a drum-type underneath drive electric control pumping unit, which consists of an electromotor, a reductor, an electric control box, a weight box, a draw bail and a frame. The utility model is characterized in that the drum wheel is provided with helical grooves in left and right directions; a set of underneath drive wire ropes are enwound and then fixed in the helical grooves on one end with the other end fixed to bottom surface of the weight box; one end of another set of upper drive wire ropes is enwound and then fixed in the helical grooves and the other end is connected to top surface of the weight box; one end of a set of pump pulling wire ropes is fixed to top face of the weight box and the other end is arranged on the draw bail through hoisting sheaves. The hoisting sheaves and drive rope sheaves are arranged on top of the frame, and the electromotor, the reductor and the drum wheel are arranged below in the frame. The utility model is characterized in low dissipation of energy and low cost, noise, no easily worn parts, easy installation and convenient well repair and so on.

Description

The cylinder type below drives automatically controlled pumping unit

Affiliated technical field:

The utility model belongs to the oil recovery machiner technical field, and specifically, what it related to is that a kind of cylinder type below drives automatically controlled pumping unit.

Background technique:

At present, beam pumping unit is generally used in the oil field, and counterweight is calculated very complicated, is difficult to find best counterweight value, and power consumption is big, and the stroke jig frequency can not arbitrarily be adjusted, and manufacturing efficiency is low.In recent years, at this situation, domesticly developed several new pumping units, and obtain remarkable result aspect energy-conservation, but these types mostly had been friction types, particularly there are some shortcomings in the wire rope friction type.As wire rope maintenance problem, there is oil easily to produce and skids, the stroke position that configures often changes; can not stablize operation, no oil will reduce working life, because of the rubber parts that adopts on the friction wheel; working life is very short, and renewal cost is very high, and needs to shut down stopping production.On the one hand ballast box moves up and down and needs guide rail, upper saw pulley again, and operational noise is big, and directed slideway, pulley are easy to wear, need shut down stopping production during replacing, have a strong impact on field produces.

Summary of the invention:

The purpose of this utility model is at the problems referred to above, provides a kind of energy consumption, cost low, and noise is little, does not have easily worn part, installs simply, and well workover drives automatically controlled pumping unit in the cylinder type below easily.

For this purpose, the utility model adopts following technological scheme: comprise by motor, speed reducer, electric control box, ballast box, draw bail, the cylinder type below that frame is formed drives automatically controlled pumping unit, it is characterized in that drum wheels [7] is provided with sieve spin slot of left and right sides different direction, one group of bottom shackle line [6] twines the back in drum wheels [7] sieve spin slot fixing, the other end be fixed on ballast box [5] below, one end of another group top shackle line [3] twines the back in drum wheels [7] sieve spin slot fixing, the other end by transmission rope sheave [2] be connected to ballast box [5] above, one group of end that leads pump wire rope [4] be fixed on ballast box [5] above, the other end is installed on the draw bail [12] by head sheave [1], head sheave [1], transmission rope sheave [2] is installed in the top of frame [11], motor [9], speed reducer [8], drum wheels [7] is arranged on the below in the frame [11].

Described is that electric control box [10] has insulation interlayer and temperature control device.

The utlity model has following characteristics: 1, energy consumption, cost are low, and noise is little, does not have easily worn part, install simply, and well workover is convenient; 2, power assemblies such as the motor of pumping unit, speed reducer, drum wheels are arranged on the below in the frame, and center of gravity is low, good stability; 3, electric control box has insulation interlayer and temperature control device, and no matter under extremely hot or severe cold condition, automatical control system can both proper functioning; 4, the wire rope roll barrel whell is adopted in the pumping unit transmission, does not produce skidding, stable equipment operation, and when two head sheaves are installed, and the machine of can realizing is taken out the efficient function of two wells.
