Description
Technical field
Slow down and the efficient oil pumping with single movable pulley the present invention relates to field of petroleum machinery, more particularly to a kind of belt
Machine.
Background technology
The operation such as well workover or well-flushing is frequently necessary in oil pumping in oil fields operation process, is at this time needed in the vertical direction of oil well
Want the horse head or directive wheel of pumping unit or the structure of the class of leading arm one to concede certain space, so can just be easy to operation to set
Standby lifting sucker rod.Existing new pumping unit is broadly divided into complete machine resigning, leading arm according to its design feature and rotates backward and allow
Position, electronic resigning etc. are several, and wherein complete machine is stepped down due to the operation for needing whole equipment being moved rearwards by, therefore structure is multiple
It is miscellaneous while consumable quantity is big, and degree of safety is poor, can not show a candle to other several resigning modes flexible.The leading arm mode that rotates backward typically is tied
Structure bulky complex, and the driving source not rotated as leading arm using itself actuator, it is cumbersome, and also leading arm turns round
On the one hand flowing mode limits the space adjusted before and after leading arm when well head is aligned, and another aspect leading arm is risen after turning over
Sky, then security is not high if running into lifting tape jam and needing manually to go operation.And most external rotor electric machine direct drive types
Oil pumper, which can not be realized, voluntarily puies forward counterweight, it is necessary to assist to reduce practicality on ability, certain depth by crane.
Other existing oil pumper uses winding type structure, and such as transmission system is rigidity, then hole condition is severe sometimes, suddenly card
Pump etc. will be impacted when occurring to the transmission system such as elevator belt or steel wire rope, motor, and influenceing its life-span, there is also equipment simultaneously
Potential safety hazard.This structure is removed due to being fixed on to elevator belt or steel wire rope in equipment, therefore during for well head centering simultaneously
