Down stroke, since the dead weight of rod string drives the horse head 12 of pumping unit to move downward, i.e., walking beam 11 is put clockwise
Dynamic, walking beam 11 pushes piston rod 13C to move downward by axis pin at this time, and the oil storage between hydraulic cylinder cylinder sleeve 13E and piston 13D is empty
Between reduce, the Incoercibility of hydraulic oil so that oil pressure increases in cylinder barrel, further such that the check valve in oil inlet pipe system
14A is opened, and hydraulic oil after cylinder barrel oil outlet 13A pressure releases by flowing back into fuel tank 7,7 position of reflux and fuel tank of hydraulic oil
Raising, hydraulic energy transfer is stored for potential energy, is prepared for next stroke.Simultaneously because the reduction of area of passage,
So that piston rod 13C declines is obstructed, thereby reduces speed of the walking beam 11 to lower swing, motor no longer does negative work at this time, reaches
The effect of balance.
Upstroke, under the drive of crank 4, walking beam 11 starts counter-clockwise swing, and walking beam 11 is pulled by axis pin and lived at this time
Stopper rod 13C is moved upwards, and the oil storage space between hydraulic cylinder cylinder sleeve 13E and piston 13D increases, and oil pressure reduces in cylinder barrel, uses
Check valve 14B in oil pipe line system is opened, and hydraulic oil enters hydraulic cylinder chamber by hydraulic cylinder fuel feed hole 13B and reacts on
Piston 13D, and then walking beam 11 is pushed to be swung up.The potential energy of the hydraulic oil stored in upper one-stroke simultaneously balances part oil pumping
The weight of roofbolt reduces motor work done during this, has achieved the effect that balanced energy conservation.
