Abstract
The utility model provides oil pumping equipment of an oil field. A machine frame and a movable pulley are arranged on the front part of the existing walking beam type oil pumping machine to form the oil pumping equipment of an oil field. The oil pumping equipment of an oil field is characterized in that the machine frame is arranged on the front part of the walking beam type oil pumping machine, and the movable pulley or a movable pulley set is hung on the lower surface of the machine frame. One end of a steel wire rope on the movable pulley or the movable pulley set is fixed on the machine frame, and the other end of the steel wire rope on the movable pulley or the movable pulley set is fixed on another movable pulley or on the front end of the rocker of the walking beam type oil pumping machine. The utility model has the advantages of simple structure, stable running, and easy assembly. The easy damaging members of the oil pumping equipment of an oil field are convenient to be replaced. The energy-saving effect of the oil pumping equipment of an oil field is more than 30%.
Description
The utility model relates to a kind of pumping unit of oil field, is a kind of pulley type beam-pumping unit.
The oil field is a beam pumping unit from the capital equipment of underground extraction crude oil at present.This machine is to drive bent thick stick wheel by motor, reductor, connecting rod and rocking bar extract crude oil from oil well, because the thickness of crude oil and the degree of depth of down-hole of living in, therefore, then need very big draft during extraction, adding this oil pumper again is directly by rocking bar oil well to be extracted (acting), so, not only the each several part movement parts desired strength of complete machine is big, and the motor coupling is also very big.Like this, just make this machine not only heaviness but also the height that consumes energy.
The purpose of this utility model provides a kind of energy-conservation pulley type beam-pumping unit.
The purpose of this utility model is achieved in that this machine still adopts the basic structure of existing beam pumping unit.Just want miniaturization according to existing beam type oil pumping, the motor coupling is littler.Its principal character is, be provided with a frame in the front portion of beam pumping unit, movable pulley of suspension or running block below frame, wire rope one end on this movable pulley or the running block is fixed on the frame, and the other end then is fixed on another movable pulley or the rocking bar front end of beam pumping unit.Its energy-saving principle is: with original oil pumper directly to the oil well work done, change into through movable pulley indirectly to oil well oil-pumping acting, to reach the body weight that reduces oil pumper and the purpose of power consumption.
Narrate embodiment according to accompanying drawing below.
Accompanying drawing is the structural representation of pulley type beam-pumping unit.
As shown in drawings: this machine is made up of existing beam pumping unit and frame and movable pulley.Beam pumping unit be by on the base 1 fixedly rocking bar frame 2 and motor frame 3, on rocking bar frame 2, be provided with rocker shaft 4, on motor frame 3, establish motor 5, reductor 6 and bent thick stick wheel 7, connecting rod 8 and rocking bar 9 and constitute.The rear portion of rocking bar 9 is articulated in rocking bar frame 2 through rocker shaft 4, and the middle part of rocking bar 9 also is articulated in connecting rod 8, and is provided with sheave 10 at the front end of rocking bar.The rocking bar front end of existing beam pumping unit has arc hammer (being commonly called as horse head), extracts crude oil in the following oil well with the wire rope that has on the arc hammer.And this oil pumper is to be provided with a cantilevered frame 11 in the front portion of existing beam pumping unit, is fixing fixed pulley 12 and 13 on frame 11.Wire rope 14 1 ends connect and are fixed on the sheave 10 of rocking bar front end, and the other end then is fixed on the frame 11 through fixed pulley on the frame 11 12 and 13 moving pulleys 15, this is that a kind of basic model of this oil pumper is (if like this, oil well is just corresponding below movable pulley 15), but, in order better to bring into play the laborsaving characteristics of movable pulley, to reach bigger energy-saving effect, can also on movable pulley 15, be provided with gib head 16, end with wire rope 17 is fixed on the gib head 16, and the other end then moving pulley 18 is fixed on the frame 11 again.Also can be fixed on an end of wire rope 20 on the gib head 19 in the same way, the other end then moving pulley 21 is fixed on the frame 11 again, and oil well is just corresponding below gib head 22 like this.According to above-mentioned frame mode, can hang 1 movable pulley or 2-5 running block below the frame, if it is also passable to be provided with more movable pulley, but too cumbersome.
The utility model is simple in structure, running steadily, assembling easily and consumable accessory be convenient to change, its energy-saving effect is more than 30%.
Claims (3)
1, a kind of pulley type beam-pumping unit, it comprises beam pumping unit, it is characterized in that: be provided with a frame in the front portion of beam pumping unit, movable pulley of suspension or running block below frame, wire rope one end on this movable pulley or the running block is fixed on the frame, and the other end then is fixed on another movable pulley or the rocking bar front end of beam pumping unit.
2, pulley type beam-pumping unit according to claim 1 is characterized in that: can hang 1-5 movable pulley below the frame.
