Abstract
The utility model discloses a hydraulic balancer of a beam-pumping unit. The hydraulic balancer of the beam-pumping unit comprises balancing weights located on a balance beam. The balancing weights are composed of the quantitative balancing weight and the variable balancing weight. The variable balancing weight is a balance weight water tank fixedly arranged at the tail end of the balance beam. The balance weight water tank is provided with a water inlet pipeline, a water outlet pipeline and a vent hole. The water outlet pipeline is connected with a water pump station. The water pump station is sequentially composed of a water tank, a first two-position three-way valve, a water pump, a one-way valve and a second two-position three-way valve according to a water path. When water is supplied to the water tank through the second two-position three-way valve, water supplied through the first two-position three-way valve is provided through the water tank of the water pump station. The balance weight water tank supplies water to the water tank of the water pump station through the second two-position three-way valve.

Background technique
Pumping unit is one of capital equipment of petroleum industry suction crude oil, what the conventional ground machine oil production equipment in our times various countries more than 80 percent adopted is the beam-pumping unit of crank balance, the method of the beam-pumping unit adjustment moment of crank balance is to rely on the mobile balancer weight on crank that is added in, labor intensity is large, also dangerous.
The counterbalance effect of pumping unit not only affects the energy consumption of pumping unit, but also affect working life of pumping unit itself, therefore beam pumping unit dynamic leveling weighing apparatus in operation is the key technology of sinking pumping unit power consumption, is the direction of beam pumping unit Energy Conservation.
Notice of authorization CN 203585202 U notice of authorization day 2014.05.07 disclose a kind of beam-balanced pumping unit automatic adjustable balance refitting and have put, and comprise base and motor fixed thereon, retarder and balancer weight; Described base is provided with guide rail, and described balancer weight and guide rail form and be slidably matched; Described motor connection reducer, retarder connects leading screw, and described balancer weight is socketed on leading screw and is mated reciprocating linear and moves.This balancer weight regulating device can be adjusted the balance of pumping unit, the high-altitude hazards while having avoided manual operation etc. in non-stop-machine situation.Can not realize the transient equiliblium problem of walking beam in oil pumping process.Notice of authorization CN 201714355 U notice of authorization day 2011.01.19 disclose a kind of hand and electric two-purpose balace weight of beam-balanced pumping unit, mainly by balancer weight (1), equalizer bar (2), stretching bar (3), speed reducer (4). and base (5), guide beam (6), hinge (7), belt pulley (8), motor (9) and handle (10) form.The front end homostasis heavy (1) of stretching bar (3) is articulated and connected, hinge for the other end (7) the homostasis beam (2) of stretching bar (3) is hinged, at the middle part of stretching bar (3), a screw rod that two rotation direction is contrary is housed, external part in screw rod bottom is equipped with speed reducer (4), the input end of speed reducer (4) is equipped with belt pulley (8), at the front end of belt pulley (8), being equipped with can double-swing ratchet, with motor (9) or handle (10), rotate the screw rod at stretching bar (3) middle part, stretching bar (3) will elongate or shorten, balancer weight (1) is swung forward or backward, thereby completed the adjustment work of trimming moment.But the balance that this structure drives weighs several tons heavy, need the motor of relatively high power, power consumpiton is large, and needs the cycle repeatedly to commutate, start frequently and the impact force that motor is subject to of commutating larger, affect working life.
Summary of the invention
The above-mentioned defect existing for solving prior art, it is little that the purpose of this utility model is to provide a kind of power loss, the hydraulic balancer of the beam pumping unit that transient equiliblium is effective.
For achieving the above object, the utility model adopts technological scheme: the hydraulic balancer of this beam pumping unit comprises the balancer weight being positioned on equalizer bar, it is characterized in that: described balancer weight consists of quantitative balancer weight and variable balancer weight, described variable balancer weight is the counterweight water tank that is fixedly installed on equalizer bar end, counterweight water tank has intake pipe, outlet conduit and exhaust port, and described intake pipe connects the water outlet of pumping station; Described outlet conduit connects the water intake of pumping station; Described pumping station is fixedly installed on the nearly fulcrum side of equalizer bar, and described pumping station consists of water tank, the first two position three-way valve, water pump, one-way valve, the second two position three-way valve successively by water route; The water inlet of described the second two position three-way valve during to counterweight water tank water intake, the first two position three-way valve is the cistern water supply by pumping station; Described the second two position three-way valve is by counterweight cistern water supply during to the cistern water supply of pumping station, and the commutation of a described two position three-way valve, two two position three-way valves is controlled by the torque sensor of pumping unit.
Described quantitative balancer weight consists of iron sheet tube and the cement being loaded in iron sheet tube.
Described counterweight water tank outer wrap has the cement layer of thermal-insulated counterweight.
Adopt the beneficial effect of technique scheme: the hydraulic balancer of this beam pumping unit consists of quantitative balancer weight and variable balancer weight, when the moment that quantitatively balancer weight produces is unloaded with beam-pumping unit, the moment of horse head side equates, the loading moment that variable balancer weight increases when upwards pumping according to pumping unit is adjusted, the water being about in pumping station is evacuated to the counterweight water tank that is positioned at walking beam end, moment and the loading moment of water generates that enters counterweight water tank is suitable, thereby reduced the power consumption of pump machine when oil pumping, good energy-conserving effect.In the unloaded descending process of pumping unit, according to horse head side force square, reduce situation, pumping station is evacuated to the water in counterweight water tank in the water tank of pumping station, and the moment that counterweight water tank forms is corresponding reducing also, and the moment that the amplitude reducing and horse head side reduce adapts.The motor power (output) of pumping station is less, and without impact force impact, has improved working life.Two two position three-way valve electromagnetic responses are fast, and flow is adjustable, can realize the adjustment variable torque of fast stepless, can guarantee that pumping unit is all the time in state of equilibrium, thereby greatly reduce the energy consumption of pumping unit, extend the life-span of rod pump, reduce cost for oil production.
