Abstract

The utility model discloses a floor type electric-control friction pumping unit. An electric-control box, a motor, a speed reducer, a driving wheel and a driving shaft supporting seat are orderly connected and fixed on the foundation of ground concrete. Two well frames are erected and fixed on both sides of the driving wheel. A fixed cross beam crosses above the well frames. A driven guide supporting wheel is respectively hinged on the transverse beam in the positions above the well frames. A well rope is in frictional connection with the driving wheel and the driven guide supporting wheel. One end of the well rope is fixedly connected with a balance weight, and the other end is fixedly connected with a traction clamp. Compared with a conventional beam pumping unit, the power of the motor is reduced by a half, and the power factor of the motor is increased by one time; the power of the speed reducer is raised by one third, and the oil pumping efficiency is raised by about 45%; the utility model has the advantages of slow lower running and rapid upper running, small abrasion of a pumping rod and long repair period. Compared with a friction type pumping unit, the utility model has the advantages of material saving, low cost, reduced volume for dismounting transportation, and simple and convenient manufacture, installation, operation and maintenance.

Description

Console mode voltage-controlled friction oil pumper

Affiliated technical field

The utility model relates to a kind of console mode voltage-controlled friction oil pumper, belongs to the oil recovery machiner technical field.

Background technology

Existing oil field equipment is the machine of kowtowing that the fifties is just brought into use, power consumption is big, lift is short, because the continuous variation of angle causes the sucker rod unbalance stress, the deep-well oil-extraction resistance is bigger, other has a kind of frame type oil pumper, because of its power is arranged at the derrick the top, to install, use, maintenance is all very inconvenient, vibration, noise that the equipment operation is produced are bigger, also there is potential safety hazard simultaneously in less stable.

Summary of the invention

The utility model provides a kind of console mode voltage-controlled friction oil pumper at the problems referred to above, and it can be saved electric energy, reduce the deep-well oil-extraction resistance, can make installations, use again, keep in repair more convenient.

Task of the present utility model is finished as follows: electric control box, motor, reductor, driving wheel, driving shaft bearing are connected successively and be fixed on the ground concrete basis, erect and fix two derricks in the driving wheel both sides, derrick top cross-arm fixed cross beam, on the crossbeam of derrick top position respectively hinged one from the action-oriented support wheel, the rope for drawing water from a well friction connects driving wheel and reaches from the action-oriented support wheel, the fixedly connected counterweight of rope for drawing water from a well one end, the fixedly connected draw bail of the other end.

The utility model adopts the rotating reversing motor, drive driving wheel through reductor, counterweight is done a day flat-shaped motion with traction oil pumping load under the rope for drawing water from a well traction drives, if the design counterweight adapts to the oil pumping lotus, can obtain the seesaw movement effects, the experiment results of measuring shows that the utility model is compared with conventional beam-pumping unit, power of motor can reduce half, motor power factor doubles, and reductor power improves 1/3, and pumping efficiency can improve about 45%, the floor mounted actuating unit is simple and convenient, damage little, operation is gone up fast down slowly, and the sucker rod wearing and tearing are little, and the time between overhauls(TBO) is long, compare with the friction-type oil pumper, materials are economized, cost is low, maintenance cost is low, and the disassembled for transport reduced volume is made, install, use, maintenance, simple and convenient, very practical.
