Description
Technical field
The utility model relates to a kind of oil exploitation device, particularly a kind of beam pumping unit.
Background technology
Beam pumping unit is the oil recovery machiner used extensively, in a large number in oil field, compares have the advantages such as structure is simple, dependable performance, maintenance maintenance are convenient compared with the oil recovery machiner of other types.But beam pumping unit is because of its intrinsic quadric chain, make the displacement of point suspension movement, speed and accelerating curve be presented as the regularity of distribution of approximate just (remaining) string function, this unalterable characteristics of motion adds that the impact of the unfavorable factors such as the polytropy of downhole load and polished rod deformation makes conventional beam pumping unit occur the problems such as system loss is large, efficiency is low, equipment failure rate is high.
In view of above-mentioned defect, the utility model creator obtains this creation finally through long research and practice.
Summary of the invention
The purpose of this utility model is to provide a kind of beam pumping unit, overcomes the deficiency of above-mentioned prior art, and it can effectively solve, and existing beam pumping unit stroke is short, discharge capacity is little, the higher and unhandy problem of energy consumption.
For achieving the above object, the technical solution adopted in the utility model is: a kind of beam pumping unit, comprise motor, reducer, traffic cycle, movable weight, ballast box, pitman shaft, connect walking beam, crossbeam connecting rod, support shaft, horse head, lifting rope, polished rod eye, support, base, belt, described motor, reducer and support are all arranged on base, described motor is connected with traffic cycle by belt, described traffic cycle is arranged on reducer, described traffic cycle by pitman shaft and crossbeam connecting rod be connected walking beam and connect, described ballast box and connection walking beam connect, movable weight is placed with inside ballast box, described connection walking beam is connected with horse head, connect walking beam to be connected with support by support shaft again.
Further, counter weight device is ballast box, and the upper end of described ballast box is arranged on the right-hand member of walking beam, and the lower end of ballast box is installed with movable weight.
Further, connect walking beam and be arranged on traffic cycle by crossbeam connecting rod, the upper end of ballast box is arranged on the right-hand member of connection walking beam, and the lower end of ballast box is installed with movable weight.
Further, reducer is arranged on base, and traffic cycle is arranged on reducer.
The utility model reasonable and compact in structure, easy to use, it realizes long stroke by the length changing crossbeam connecting rod, meets huge discharge oil recovery and produces, reliability is high, save oil pumper manufactures raw material, reduces production run energy consumption, balancing and handling safety, convenient, fast.
