Specific embodiment
During petroleum collection, oil well is after going dead, it is also necessary to be aspirated the petroleum in oil well with pumping unit
Out.According to the difference of Pumping Unit and principle, pumping unit can be divided into beam pumping unit and without beam pumping unit.
The basic characteristics of beam pumping unit are that structure is simple, manufacture is easy, it is easy to use especially he can exist for a long time
The round-the-clock operating in oil field, using reliable.The working principle of beam pumping unit is supplied power by engine, will be moved through retarder
Power machine tells rotation to become the vulgar rotation of pumping unit deicing, and becomes taking out by rotary motion from crank-connecting rod-walking beam mechanism
Oil machine horse head pumps, and drives deep-well pump work into polished rod eye assembly.The main component of beam pumping unit mentions
For the engine of power, the retarder for transmitting power and reducing speed, transmitting power and rotary motion is become into reciprocating motion
Four-bar mechanism (crank, connecting rod, walking beam, bracket and crossbeam and pedestal) transmits power and guarantees that polished rod does linear reciprocating motion
Horse head and polished rod eye assembly make oil pumping function rest on the brake gear of any position and to make power function lesser negative
Carry the balancing device etc. to work in variation range.
Beam pumping unit can be divided into conventional type beam pumping unit, prefix type beam type is taken out according to structure type difference
Oil machine, out-phase type beam pumping unit, double horse head type beam pumping units.Beam pumping unit can divide according to balance mode difference
Are as follows: beam balance type, crank balance type, composite balanced-type, air-balance type.
No beam pumping unit includes chain drive pumping unit, steel rope oil sucking machine, hydraulic pumping unit, crank-linkage type pumping unit
Deng.Wherein, the working principle of chain drive pumping unit is that engine supplies power, and the high-speed rotation of power is become chain through retarder
Slowly run, and rotary motion is become into the round-trip frame of pumping unit up and down reciprocatingly from particular link and king-pin-slide block mechanism
Movement, through driving deep-well pump work around the polished rod eye assembly of crown sheave.Mainly by power drive system, exchange system, balance
The composition such as system, suspending weight system and gantry base.Chain drawer is organic to have compact-sized, balance adjustment Fang Baini, stroke long
Equal remarkable advantages, especially suitable for being applied in mainframe and offshore oil production platform or from the oil recovery of formula well.
The work characteristics of pumping unit is subject to stress alternation.When upstroke, oil pumping machine polished rod load is to act on piston to have
Liquid weight (including pressure difference) and rod string weight in a liquid and friction, inertia, the vibration etc. imitated on section are moved
Load；When down stroke, oil pumping machine polished rod load is the weight and dynamic loading of rod string in a liquid.And when upstroke, start
It is confidential to pay very big energy and go to lift polished rod load；When to down stroke, sucker rod can fall by self weight, not need singly
Engine pays energy, and valve does manual work to engine.Therefore, engine is non-uniform in the load of up-down stroke.Load
Inhomogeneities has severely impacted efficiency and the service life of four-bar mechanism, reduction gearbox and engine, has also been degrading the work of sucker rod
Condition dramatically increases rod broken number.
Wherein, it because direct-drawing type pumping unit has many advantages, such as that stroke is big, low energy consumption, high-efficient, and is widely used each
In elephant.During operation, load constantly changes pumping unit, and the load of down stroke has differences thereon, causes motor defeated
Electric current is unstable out, is easy to damage the equipment such as motor.Therefore, it is typically provided with counter weight of beam unit on pumping unit, led to
Increase and decrease counter weight of beam unit is crossed, achievees the purpose that balancing load.
In the prior art, balancing device includes storage case and multiple balance weights for being placed in storage case, and outside is set
It is equipped with protective net.When needing adjustment block, protective net is opened, manual handling balance weight is placed into storage case or calm
It receives to move out in case and be placed on ground.
General balance weight weighs 30 kilograms, and site operation personnel carries back and forth, not only great work intensity, operator's danger
It is dangerous big, it is be easy to cause personal injury, and carrying adjustment time is long back and forth, causes the shutdown of pumping machine time long, oil recovery efficiency
It is low.Also, balance weight is placed on outside oil pumping box body, is easily lost.It, need to be by balance weight and pumping unit when transporting pumping unit
Ontology separately transports, and transportation cost is high.
For this purpose, the present invention provides a kind of balance regulator and pumping unit, balance weight labour is carried to solve field worker
The technical issues of intensity is big, adjustment time is long, low efficiency.
Below in conjunction with attached drawing, detailed description of the preferred embodiments, it should be appreciated that retouches in this place
