Abstract
A belt tension device for oil pumping machine mainly solves the problem that the service life of the existing belt tension device hydraulic pump is short and the accident rate is high. The utility model is characterized in that a bevel clutch (5) and a hydraulic pump (2) are connected with one end of the tension pulley (1) axle in sequence; a check valve (6), an oil pressure gage (9) and a pressure regulating reflux valve (7) are connected in series on the flow line (4) in sequence; the hydraulic pump (2) is connected with an electromagnetic hydraulic pump controller (10) and a pressure regulating starter switch (8) in sequence through the conducting wire; a jack (12) is connected with the space between the lower separator (11) of the movable support and the fixed support; and the chamber and the fluid chamber of the jack (12) are connected with the pressure regulating reflux valve (7) and the hydraulic oil tank respectively. The belt tension device has advantages of long service life of the hydraulic pump and low accident rate.
Description
Technical field:
The utility model relates to oil recovery field, oil field pumping unit drivign belt used tension device, particularly Leather Belt Tension Device on Pumping Unit.
Background technique:
Present pumping unit uses comparatively extensive in mechanical oil recovery, and the power of pumping unit, is pumped by the connecting rod drive by crank by belt transmission speed reducer by motor again, reaches the purpose of oil recovery.And the degree of tightness of belt directly affects the efficient and the cost of pumping unit.And belt stretcher is that tension wheel shaft directly links to each other with oil hydraulic pump at present, so just cause oil hydraulic pump to turn round with pumping unit continuously for a long time, thereby shortened the working life of oil hydraulic pump, the accident rate of oil hydraulic pump frequently occurs, maintenance load increases, reduce tension effects, directly influenced recovery rate.
The model utility content:
In order to overcome the deficiency that working life is short and accident rate is high of existing belt stretcher oil hydraulic pump, the utility model provides a kind of Leather Belt Tension Device on Pumping Unit, and this belt stretcher has the long service life and the low characteristics of accident rate of oil hydraulic pump.
The technical solution of the utility model is: this Leather Belt Tension Device on Pumping Unit comprises that being hinged with the upper end on the fixed support is fixed with the travel(l)ing rest of Idle wheel, be connected with jack between travel(l)ing rest bottom end rail and the fixed support, oil hydraulic pump is by advancing, oil outlet tube communicates with hydraulic oil container, clutch, one-way valve, adjustable pressure reflux valve, but pressure regulation starter switch, oil pressure gauge, electromagnetic hydraulic pressure pump controller and jack, tension wheel shaft one termination is connected with conical clutch and oil hydraulic pump in turn, be in series with one-way valve on the oil outlet tube successively, oil pressure gauge, adjustable pressure reflux valve, but oil hydraulic pump links to each other with electromagnetic hydraulic pressure pump controller and pressure regulation starter switch successively by lead, be connected with jack between travel(l)ing rest bottom end rail and the fixed support, jack hydraulic chamber and oil pocket communicate with adjustable pressure reflux valve and hydraulic oil container respectively.
The beneficial effect that the utlity model has is: this Leather Belt Tension Device on Pumping Unit is in series with one-way valve and electromagnetic hydraulic pressure pump controller owing to be connected with conical clutch and oil hydraulic pump in turn in tension wheel shaft one termination on the oil inlet pipe.Under the state of pumping unit running, but can adjust the degree of tightness of belt by adjusting adjustable pressure reflux valve and pressure regulation starter switch, when belt is loose or tight, but the pressure regulation starter switch opens the electromagnetic hydraulic pressure pump controller, oil hydraulic pump is connected with Idle wheel by clutch, oil hydraulic pump is rotated, oil hydraulic pump is controlled the jack pair belt application of force or is subtracted power, reach the purpose that the belt degree of tightness is adjusted, had only like this that oil hydraulic pump just starts under the inappropriate situation of belt degree of tightness, thereby prolonged the working life of oil hydraulic pump, reduced the oil hydraulic pump accident rate, improve tension effects, but also can carry out manual adjustment by jack at any time, improved the pumping unit working efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is left views of Fig. 1.
1-Idle wheel among the figure, 2-oil hydraulic pump, 3-oil inlet pipe, 4-oil outlet tube, 5-clutch, 6-one-way valve, 7-is adjustable pressure reflux valve, but 8-pressure regulation starter switch, 9-oil pressure gauge, 10-electromagnetic hydraulic pressure pump controller, 11-bottom end rail, 12-jack.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Figure 2, this Leather Belt Tension Device on Pumping Unit comprises that being hinged with the upper end on the fixed support is fixed with the travel(l)ing rest of Idle wheel 1, be connected with jack between travel(l)ing rest bottom end rail and the fixed support, oil hydraulic pump 2 is by advancing, oil outlet tube (3,4) communicate with hydraulic oil container, clutch 5, one-way valve 6, adjustable pressure reflux valve 7, but pressure regulation starter switch 8, oil pressure gauge 9, electromagnetic hydraulic pressure pump controller 10 and jack 12,1 one termination of Idle wheel is connected with conical clutch 5, one end of conical clutch 5 links to each other with oil hydraulic pump 2, be in series with one-way valve 6 successively on the oil outlet tube 4 of oil hydraulic pump 2, oil pressure gauge 9, adjustable pressure reflux valve 7, link to each other with electromagnetic hydraulic pressure pump controller 10 by lead on the oil hydraulic pump 2, but electromagnetic hydraulic pressure pump controller 10 links to each other with pressure regulation starter switch 8, but the pressure of adjustable pressure reflux valve 7 is slightly less than the pressure of pressure regulation starter switch 8, be connected with jack 12 between travel(l)ing rest bottom end rail 11 and the fixed support, jack 12 hydraulic pressure cavity and oil pocket communicate with adjustable pressure reflux valve 7 and hydraulic oil container respectively.
During actual the use, when belt is loose or tight, but pressure regulation starter switch 8 opens electromagnetic hydraulic pressure pump controller 10, oil hydraulic pump 2 is connected with Idle wheel by clutch 5, oil hydraulic pump 2 is rotated, oil hydraulic pump 2 is controlled the jack pair belt application of forces or is subtracted power, reached the purpose that the belt degree of tightness is adjusted, have only like this that oil hydraulic pump 2 just starts under the inappropriate situation of belt degree of tightness, thereby prolonged the working life of oil hydraulic pump 2, reduced oil hydraulic pump 2 accident rates, improved tension effects, but also can carry out manual adjustment by jack at any time, improved the pumping unit working efficiency.
