Abstract
A symmetrical balance front-located pumping unit for the mechanical oil production of the oil industry consists of a walking beam10, a back horse head 11, a bracket 7, an adjustable heavy basket12, an impact regulating 8, a brace 5 and a connecting rod 4. The connecting rod 4, a beam 3, a reducer 6 and the brace 5 are arranged in front of the centerline of the bracket 7. The back end of the walking beam 10 hangs the adjustable heavy basket12 on the back horse head 11 via a hoisting cable 2, which reduces the torque of the pumping unit peak valve and decreases the torque fluctuation. The utility model has the advantages of obvious energy saving effect, energy consumption reduction of about 40 percent, debased the acceleration of the suspension centre, stable running, low noise, long service life of the equipment, added impact regulating mechanism and convenient operation.
Description
The utility model is a kind of low energy consumption pumping unit that is used for petroleum industry machinery oil production, specifically, is symmetrical balance front-located mode pumping unit.
At present, conventional beam pumping unit commonly used both at home and abroad, be to drive retarder and crank by motor, and the horse head swing that drives walking beam and be contained in the walking beam front end by connecting rod is finished the oil pumping action to drive sucker rod and oil well pump to-and-fro motion, its deficiency is: need to be equipped with more powerful motor, thereby energy consuming ratio is bigger.
The purpose of this utility model is to provide a kind of advantage that had both had preposition pumping unit, guarantees the symmetrical balance front-located mode pumping unit of a kind of low energy consumption of conventional machine composite balance simultaneously.
The utility model is achieved in that and includes horse head 1, wire rope 2, crossbeam 3, connecting rod 4, crank 5, retarder 6, support 7, transfer impact machine structure 8, beam travelling supporting axle 9, walking beam assembly 10, back horse head 11, adjustable counter balance basket 12, base 13, brake 14, motor 15, righting mechanism 16, retarder 6 is arranged respectively on the base 13, support 7, brake 14, motor 15, connecting rod 4 is connected with crank 5, crossbeam 4 ends are connected with horse head 1, wire rope 2 is arranged on the horse head 1, walking beam assembly 10 is connected with support 7 by beam travelling supporting axle 9, the impact machine of accent structure 8 is arranged on the support 7, walking beam assembly 10 is connected with back horse head 11, adjustable counter balance basket 12 is connected with back horse head 11, and adjustable counter balance basket 12 is arranged on the righting mechanism 16.
The utility model also adopts following technological scheme:
Crank 5, connecting rod 4 are positioned at support 7 center line front sides.
Back horse head 11 is furnished with adjustable counter balance basket 12.
On the righting mechanism 16 righting trough is arranged, the projection corresponding with righting mechanism 16 arranged on the adjustable counter balance basket 12.
Advantage of the present utility model is: overcome the shortcoming of conventional front-located mode, the pumping unit Peak torque is reduced, torque ripple reduces, and energy-saving effect is remarkable.The suspension point acceleration is reduced, and running is steady, and noise is low, and service life of equipment prolongs, and the accent impact machine structure of increase makes more convenient operation, and has energy-saving advantages, and energy consumption reduces about 40%.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Mainly form by motor 15, retarder 6, walking beam 10, preceding horse head 1, back horse head 11, support 7, adjustable counter balance basket 12, accent impact machine structure 8, crank 5, connecting rod 4, connecting rod 4, crossbeam 3, retarder 6, crank 5 are placed support 7 center line front sides, the rear end of walking beam 10 hangs over adjustable counter balance basket 12 on the horse head 11 of back by wire rope 2, forms a kind of new front-located mode symmetrical balance pumping unit.
Adopt Libra balance and crank balance, to pumping unit up and down the imbalance of the suspending point loading of stroke carry out Balance Treatment, utilize the descending kinetic energy of suspending point loading to be up to upper dead center than fast speeds, the counterweight basket 12 of this moment is up with slow speed drive suspending point loading with the potential energy of self again; This balance method can partly reduce the upstroke acceleration, to reach the purpose that reduces polished rod load.
Simultaneously, the Libra balance is near the direct balance of suspending point loading, this balance mode good balance effect, overcome front-located mode crank pouring weight balanced oil extractor connecting rod big, the excessive shortcoming of equilibrium block that is stressed, because the composite balance that adopts Libra balance and crank balance to form, Peak torque on the retarder 6 is reduced, guarantee that retarder 6 torque ripple amplitudes reduce in the up-down stroke, so it has energy-saving effect preferably.
Down stroke retarder 6 moments of torsion and the acting in conjunction of suspending point loading moment of torsion make adjustable counter balance basket 12 and crankshaft balance weight savings energy.
The energy acting in conjunction of upstroke retarder 6 moments of torsion, adjustable pouring weight 12 and crankshaft balance weight savings will be carried on the suspending point loading, and adjustable pouring weight 12 and crankshaft balance weight savings energy are many more, and the power that motor 15 is needed is more little.
Adjustable counter balance basket 12 adjustable balance weight.
Adjustable counter balance basket 12 motion in the zone that righting mechanism 16 limits.
