Technical field
The present invention relates to a kind of walking-beam pumping unit charger, belong to the petroleum machinery pick-up unit.
Background technology
The walking-beam pumping unit form has a variety of on the market, the energy consumption difference of various walking-beam pumping units, in order to test out the energy consumption of different walking-beam pumping units, the load of standard just need be provided to oil pumper, the size of load and Changing Pattern should be identical with field working conditions, when carrying out the oil pumper energy consumption testing at present, adopting load mode is at indoor a bite experiment well of building, and utilizes the oil well pump in the experiment well to load.The method exists not enough: the one, and the load that the oil well pump in the experiment well produces can't be regulated artificially, the 2nd, uncontrollable variation can take place in load and the load variations rule of using its generation after a period of time in experiment well, can cause the energy consumption data test inaccurate.
Summary of the invention
The objective of the invention is artificially to regulate the deficiency that can occur uncontrollable variation with the load variations rule in order to overcome the load of oil pumper charger generation in the past, a kind of walking-beam pumping unit charger is provided, this device can produce loading force and the loading rule that the tester wants, and installs the loading force that produces simultaneously and load rule can not change along with the time of installing use.
The technical solution used in the present invention is:
A kind of walking-beam pumping unit charger of the present invention, mainly by 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 is formed, on the described hydraulic jack fixing horizontal ground, piston rod end in the hydraulic jack connects long wire rope, long wire rope by the fixed pulley that is fixed on ground after, convert state perpendicular to the ground to by horizontality, long wire rope links to each other with the lower end of spring then, and the upper end of spring links to each other with the walking-beam pumping unit horse head by strap; By the reversal valve control piston bar side-to-side movement in the 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 walking-beam pumping unit horse head is fixed, and the movement velocity in any moment is known, and strap and long wire rope are subjected to pulling force all the time simultaneously; When the walking-beam pumping unit horse head moved downward, piston rod moves right speed, and to move downward speed than walking-beam pumping unit horse head fast, and then spring is elongated, and it is big that loading force becomes; Piston rod moves right speed, and to move downward speed than walking-beam pumping unit horse head slow, and then spring shortens, and loading force diminishes.When the walking-beam pumping unit horse head moved upward, piston rod movement velocity left was slower than the walking-beam pumping unit horse head speed that moves upward, and then spring is elongated, and it is big that loading force becomes; Piston rod movement velocity left is faster than the walking-beam pumping unit horse head speed that moves upward, and then spring shortens, and loading force diminishes.Come the variation of control piston bar movement velocity by automatically controlled proportional velocity regulating valve, can realize the continuous variation of loading force, reach the loading force of expection.
The present invention compared with prior art has the following advantages: 1, this device can produce loading force and the loading rule that the tester wants; 2, the loading force of device generation and loading rule can not change along with the time of device use.

Embodiment
The present invention is further described below in conjunction with drawings and Examples:
As Fig. 1, shown in Figure 2, a kind of walking-beam pumping unit charger of the present invention, mainly by 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 is formed, on the described hydraulic jack 7 fixing horizontal ground, piston rod 5 terminations in the hydraulic jack 7 are connecting long wire rope 2, long wire rope 2 by the fixed pulley 4 that is fixed on ground after, convert state perpendicular to the ground to by horizontality, long wire rope 2 links to each other with the lower end of spring 3 then, and the upper end of spring 3 links to each other with walking-beam pumping unit horse head 1 by strap 15.
As shown in Figure 2, in hydraulic control circuit, by the direction of motion of the piston rod 5 in the reversal valve 13 control hydraulic jacks 7, by the speed of automatically controlled proportional velocity regulating valve 14 control piston bars 5 movement velocitys.
In loading procedure, the moving law of walking-beam pumping unit horse head 1 is fixed, and the movement velocity in any moment is known, and strap 15 and long wire rope 2 are subjected to pulling force all the time simultaneously; When walking-beam pumping unit horse head 1 moved downward, piston rod 5 moves right speed, and to move downward speed than walking-beam pumping unit horse head 1 fast, and then spring 3 is elongated, and it is big that loading force becomes; Piston rod 5 moves right speed, and to move downward speed than walking-beam pumping unit horse head 1 slow, and then spring 3 shortens, and loading force diminishes.When walking-beam pumping unit horse head 1 moved upward, piston rod 5 movement velocity left was slower than walking-beam pumping unit horse head 1 speed that moves upward, and then spring 3 is elongated, and it is big that loading force becomes; Piston rod 5 movement velocity left is faster than walking-beam pumping unit horse head 1 speed that moves upward, and then spring 3 shortens, and loading force diminishes.Come the variation of control piston bar 5 movement velocitys by automatically controlled proportional velocity regulating valve 14, can realize the continuous variation of loading force, reach the loading force of expection.
When walking-beam pumping unit horse head 1 moves up and down, the upper end of spring 3 links to each other with pumping unit horsehead 1 by strap 15, this moment, the upper end of spring 3 also can be moved up and down, spring 3 lower ends link to each other with piston rod 5 by long wire rope 2, by the moving law of hydraulic circuit control piston bar 5, and then the characteristics of motion that can control spring 3 lower ends; The moving law of walking-beam pumping unit horse head 1 is known in operational process, so the moving law of spring 3 upper ends is known; The moving law of spring 3 lower ends can be controlled, by control spring 3 lower end displacements, and elongation that just can control spring 3, the pulling force that spring 3 produces also just can be controlled; At any time, walking-beam pumping unit horse head head 1 suffered pulling force equates that with the elastic force that spring 3 produces process realizes the loading to walking-beam pumping unit horse head 1 thus.
To load tables of data deposits in the computer 6, this tables of data comprise add certain constantly the loading force size and the angular movement speed data of piston rod 5, the test beginning, computer 6 constantly sends instruction to automatically controlled proportional velocity regulating valve 14 according to time sequencing, control the hydraulic jack 7 turnover speed oils in the automatically controlled proportional velocity regulating valve 14 regulator solution hydraulic circuits, the translational speed of oil-feed speed control piston bar 7, the elongation of the translational speed control spring 3 of piston rod 7, the elastic force that spring 3 elongation backs produce is carried on the walking-beam pumping unit 17, is walking-beam pumping unit load is provided.
