Description
Technical field
The utility model relates to oil field deep layer oil pumping machinery, is specially a kind of energy-conservation chain drive pumping unit that is suitable for long stroke, low jig frequency oil pumping occasion.
Background technology
Input exploitation along with water flooding and a large amount of low permeability oil fields, well depth and discharge capacity constantly increase under making, exploitation is dropped in extraordinary in addition oil field (as viscous crude, high coagulate oil, wax deposition, shake out etc.), oil production technology to sucker rod pumping equipment proposed long stroke, low jig frequency, greatly pump, requirement such as take out deeply.At present, the extensive oil pumper that adopts in China oil field is a beam pumping unit.It is the machine according to SY/T5044-2003 beam pumping unit standard production.These facility have simple in structure, long-lived advantage.But because of the restriction of operating principle and structure, it is low to exist mechanical efficiency, and it is not steady to work, and stroke, jig frequency are regulated difficulty, are difficult to satisfy the shortcomings such as needs, particularly energy consumption height of viscous crude.Therefore, the patent No. has been announced " chain drive pumping unit " for the Chinese patent of " 200520024328.3 ", this oil pumper adopts the transmission of duplex chain wheel link chain mechanism, thereby make drive path short, inertia mass is little, machinery driving efficiency height, chain drive synchronizing shaft pulling oil pumping pump rod when the oil pumping pump rod needs uphill process and rise; Chain drives synchronizing shaft and spur the rising of counterweight case when counterweight case uphill process; The motor of high speed rotating can ceaselessly evenly do work; Peak point current during the mechanical movement commutation is under the stable state complete machine transmission system and works less than electric current under the rated condition.Solved of the restriction of existing beam pumping unit because of operating principle and structure, be difficult to satisfy and adapt to the problem of modern oil production technology to the requirement of pumping unit, but this oil pumper still has defective on discrete structure, for example: the guide wheel quantity that adopts on the basis of duplex chain wheel link chain mechanism transmission is more, therefore easily causes mechanical energy to lose in transmission process; In addition, the counterweight case only is used to adjust and the gravitational equilibrium of the pump rod of pumping, and the electric current of motor is equal substantially when making the oil pumping pump rod of oil pumper rise and descend, and lacks the structure of energy in the time of effectively utilizing the mechanical movement commutation.
Summary of the invention
The utility model easily exists energy loss, the energy storage when shortage commutates mechanical movement and the problems such as structure that are used at the structure of existing chain drive pumping unit, and a kind of energy-conservation chain drive pumping unit is provided.
The utility model is to adopt following technical scheme to realize: energy-conservation chain drive pumping unit, comprise pylon, transmission mechanism, the counterweight case, the oil pumping pump rod, transmission mechanism comprises by two drive sprockets, be fixed in two driven sprockets on pylon top and be engaged in active respectively, the duplex chain wheel link chain mechanism that double-stranded bar on the driven sprocket constitutes, be provided with link configuration and the hinged synchronizing shaft of chain that two axial ends is made link configuration and passed through two end axles between two chains in the duplex chain wheel link chain mechanism, synchronizing shaft is provided with coupling components, and the two ends of coupling components are respectively by being connected with the oil pumping pump rod with the counterweight case by the cable wire that is fixed in the guide wheel guiding on the pylon; Be connected with cable wire between counterweight case and the oil pumping pump rod by the guide wheel guiding, in the middle of comprising, the counterweight case has the counterweight fixed body of putting the reed pipe road, put and be provided with in the reed pipe road and can meet and discuss along putting the upper and lower T-shape that reed pipe road inwall moves up and down, two are provided with spring between meeting and discussing, and put two ends, reed pipe road and are fixed with the ring-type limited block.
Described duplex chain wheel link chain mechanism is for being obliquely installed, and promptly drive sprocket and driven sprocket place straight line have angle with vertical oil pumping pump rod, like this, can reduce guide wheel quantity, and then reduce unnecessary mechanical energy loss in the transmission process.
Motor drives two drive sprockets by reducer, makes two chains in the duplex chain wheel link chain mechanism do closed circulation, drives synchronizing shaft and does closed circulation up and down.Synchronizing shaft drives the oil pumping pump rod at the decline half way by cable wire and rises, at this moment, the counterweight case descends under the deadweight effect, going up of oil pumping pump rod risen the counterweight effect, when the counterweight case drops to ground, meet and discuss down and press the spring of putting in the reed pipe road, make spring deformation, kinetic energy is converted into elastic potential energy, at this moment, synchronizing shaft enters the rising half way, drive the counterweight case by cable wire and rise, simultaneously, spring upwards promotes the counterweight case, elastic potential energy is converted into kinetic energy, and the oil pumping pump rod descends under the deadweight effect.
Compared with prior art, the utility model is on the basis of adopting the transmission of duplex chain wheel link chain mechanism, improve the counterweight case, promptly do the closed circulation motion with chain at synchronizing shaft, realize the oil pumping pump rod, when the counterweight case pumps, move back and forth in the commutation process down thereon, kinetic energy is transformed, stores, utilizes, realize that motor evenly does work, peak point current during the mechanical movement commutation is less than electric current under the rated condition, the purpose of complete machine transmission system steady operation makes full use of energy, conserve energy.
Distance between principal and subordinate's movable sprocket, the i.e. stroke of definite this oil pumper.Adjust the position of driven sprocket when generally adjusting stroke, the stroke of pylon parameter decision oil pumper when making oil pumper.
The utility model is rational in infrastructure, and is energy-conservation, in light weight, easily realize that long stroke, inertial load are little, can satisfy the requirement of modern oil production technology to the sucker rod pumping machine.
