Description
Technical field
The present invention relates to a kind of walking-beam pumping unit charger, belong to petroleum machinery pick-up unit.
Background technology
On market, walking-beam pumping unit form has a variety of, the energy consumption of various walking-beam pumping unit is different, in order to the energy consumption of different walking-beam pumping unit can be tested out, just need the load that standard is provided to oil pumper, the size of load and Changing Pattern should be identical with field working conditions, when carrying out oil pumper energy consumption testing at present, adopt load mode to be build a bite experiment well in indoor, utilize the oil well pump in experiment well to load.The method Shortcomings: one is that the load that the oil well pump in experiment well produces cannot regulate artificially, two is that uncontrollable change can occur in load and load Changing Pattern that experiment well is using its generation after a period of time, energy consumption data can be caused to test inaccurate.
Summary of the invention
The object of the invention is artificially to regulate to overcome the load of oil pumper charger generation in the past the deficiency that there will be uncontrollable change with load Changing Pattern, a kind of walking-beam pumping unit charger is provided, this device can produce the loading force and loading rule that tester wants, time that the loading force produced with timer and loading rule can not use along with device and changing.
The technical solution used in the present invention is:
A kind of walking-beam pumping unit charger of the present invention, primarily of long wire rope, spring, fixed pulley, piston rod, hydraulic jack, support, surplus valve, filtrator, hydraulic pump, reversal valve, automatically controlled proportional velocity regulating valve, strap, computer forms, on described hydraulic jack fixing horizontal ground, piston rod end in hydraulic jack connects long wire rope, long wire rope is by after the fixed pulley that is fixed on ground, state perpendicular to the ground is converted to by horizontality, then long wire rope is connected with the lower end of spring, the upper end of spring is connected with mule head of beam pumping unit by strap, by the reversal valve control piston bar side-to-side movement in hydraulic control circuit, by the speed of automatically controlled proportional velocity regulating valve control piston bar movement velocity.In whole loading procedure, the moving law of mule head of beam pumping unit is fixing, and the movement velocity in any moment is known, and strap and long wire rope are all the time by pulling force simultaneously; When mule head of beam pumping unit moves downward, piston rod moves right speed and moves downward speed soon than mule head of beam pumping unit, then spring is elongated, and loading force becomes large; Piston rod moves right speed and moves downward speed slowly than mule head of beam pumping unit, then spring shortens, and loading force diminishes.When mule head of beam pumping unit moves upward, piston rod left movement velocity moves upward speed slowly than mule head of beam pumping unit, then spring is elongated, and loading force becomes large; Piston rod left movement velocity moves upward speed soon than mule head of beam pumping unit, then spring shortens, and loading force diminishes.Carried out the change of control piston bar movement velocity by automatically controlled proportional velocity regulating valve, the continuous change of loading force can be realized, reach the loading force of expection.
The present invention compared with prior art, has the following advantages: 1, this device can produce the loading force and loading rule that tester wants; 2, device produce loading force and loading rule can not along with device use time and change.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As Fig. 1, shown in Fig. 2, a kind of walking-beam pumping unit charger of the present invention, primarily of long wire rope 2, spring 3, fixed pulley 4, piston rod 5, hydraulic jack 7, support 9, surplus valve 10, filtrator 11, hydraulic pump 12, reversal valve 13, automatically controlled proportional velocity regulating valve 14, strap 15, computer 16 forms, on described hydraulic jack 7 fixing horizontal ground, piston rod 5 termination in hydraulic jack 7 is connected to long wire rope 2, long wire rope 2 is by after the fixed pulley 4 that is fixed on ground, state perpendicular to the ground is converted to by horizontality, then long wire rope 2 is connected with the lower end of spring 3, the upper end of spring 3 is connected with mule head of beam pumping unit 1 by strap 15.
As shown in Figure 2, in hydraulic control circuit, by the direction of motion of the piston rod 5 in reversal valve 13 hydraulic control oil cylinder 7, by the speed of automatically controlled proportional velocity regulating valve 14 control piston bar 5 movement velocity.
In loading procedure, the moving law of mule head of beam pumping unit 1 is fixing, and the movement velocity in any moment is known, and strap 15 and long wire rope 2 are all the time by pulling force simultaneously; When mule head of beam pumping unit 1 moves downward, piston rod 5 moves right speed and moves downward speed soon than mule head of beam pumping unit 1, then spring 3 is elongated, and loading force becomes large; Piston rod 5 moves right speed and moves downward speed slowly than mule head of beam pumping unit 1, then spring 3 shortens, and loading force diminishes.When mule head of beam pumping unit 1 moves upward, piston rod 5 left movement velocity moves upward speed slowly than mule head of beam pumping unit 1, then spring 3 is elongated, and loading force becomes large; Piston rod 5 left movement velocity moves upward speed soon than mule head of beam pumping unit 1, then spring 3 shortens, and loading force diminishes.Carried out the change of control piston bar 5 movement velocity by automatically controlled proportional velocity regulating valve 14, the continuous change of loading force can be realized, reach the loading force of expection.
When mule head of beam pumping unit about 1 runs, the upper end of spring 3 is connected with pumping unit horsehead 1 by strap 15, now the upper end of spring 3 also can be run up and down, spring 3 lower end is connected with piston rod 5 by long wire rope 2, by the moving law of hydraulic circuit control piston bar 5, and then can the characteristics of motion of control spring 3 lower end; In operational process, the moving law of mule head of beam pumping unit 1 is known, so the moving law of spring 3 upper end is known; The moving law of spring 3 lower end can control, by control spring 3 lower end displacement, just can the elongation of control spring 3, and the pulling force that spring 3 produces also just can control; At any time, the pulling force suffered by mule head of beam pumping unit head 1 is equal with the elastic force that spring 3 produces, and process implementation is to the loading of mule head of beam pumping unit 1 thus.
Tables of data will be loaded stored in computer 6, this tables of data comprises and adds the loading force size in certain moment and the angular movement speed data of piston rod 5, test starts, computer 6 constantly sends instruction to automatically controlled proportional velocity regulating valve 14 according to time sequencing, the hydraulic jack 7 controlled in automatically controlled proportional velocity regulating valve 14 hydraulic circuit for regulating passes in and out speed oil, the translational speed of oil-feed speeds control piston rod 7, the elongation of the translational speed control spring 3 of piston rod 7, the elastic force that spring 3 extends rear generation is carried on walking-beam pumping unit 17, is walking-beam pumping unit and provides load.
