Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
In the utility model, term " first ", " second " are mainly used in distinguishing different parts, but specifically do not limit parts.The start of the utility model indication refers to the state of the motor starting fracturing pump, refers to the state of the motor without the need to starting fracturing pump during shutdown.
Be the structural representation of the fracturing pump plunger position regulating device of the utility model one embodiment shown in Fig. 1, the structure of this embodiment is used for when fracturing pump is shut down, the position of adjustment plunger, and then realizes the examine and replace of plunger and Sealing.The first gear 1 and rotation driving part is at least comprised in embodiment illustrated in fig. 1.
First gear 1 is for engaging with the second gear 2 fracturing pump being connected bent axle.This second gear 2 is existing structure in fracturing pump, and it is generally fixedly connected with bent axle.Bent axle can also be equipped with connecting rod, and bent axle drivening rod crosshead, plunger do work, and the concrete structure of each several part can with reference to technology that is existing and that improve.In fracturing pump, this second gear 2 is also gearwheel usually, and preferably the number of teeth of the first gear 1 is less than the number of teeth of the second gear 2, and namely the first gear 1 is small gear.
Should be clear, in fracturing pump, the driving mode of gearwheel generally has two kinds: one is mechanical transmission, and motor arrives coupling again to gearbox, then passes through the input gear axle of spline joint gearwheel; Another kind is hydraulic transmission, driven by engine oil hydraulic pump, and oil hydraulic pump drives oil hydraulic motor, and oil hydraulic motor drives the input gear axle of gearwheel by spline joint.Certainly, also can have other possibility driving mode, all be applicable to the technical solution of the utility model.
Rotation driving part connects the input shaft of the first gear 1, and this rotation driving part can rotate when fracturing pump is shut down.This rotation driving part is preferably independent of the structure outside existing drive system.This rotation driving part is used for position adjustment during plunger examine and replace, by driving the first gear 1 to rotate, and then makes the second gear 2 and crank rotation, thus adjusts plunger extended position as required.
Aforementioned whole position adjustment without the need to starting the motor of fracturing pump, and does not need manpower transmitting gear or prizes coupling, easy and simple to handle, and can reduce labor intensity, increases work efficiency.In addition, it is simple that this embodiment also has structure, is easy to manufacture, the advantage of the aspects such as implementation is strong.
In the embodiment shown in fig. 1, rotation driving part is oil hydraulic motor 3, and oil hydraulic motor 3 connecting fluid press pump 4, by hydraulically powered mode, realizes the adjustment of plunger position.Oil hydraulic pump 4 can be multiple possibility structure, and as a kind of mode of execution, oil hydraulic pump 4 is motor-drive pump, the input shaft of the output shaft connecting fluid pressure motor 3 of this motor-drive pump; As another kind of mode of execution, oil hydraulic pump 4 is hand pump, the input shaft of the output shaft connecting fluid pressure motor 3 of this hand pump.
Except hydraulic driving, also can adopt mechanical drive mode during plunger position adjustment, preferred rotation driving part is motor, and the output shaft of motor connects the input shaft of the first gear 1, can realize technique effect of the present utility model equally.
For the structure of hydraulic system existing in fracturing pump, such rotation driver part, by the track remodelling in hydraulic system, realizes its rotation when fracturing pump is shut down.It is the structural representation of the fracturing pump plunger position regulating device of another embodiment of the utility model shown in Fig. 2, this embodiment at least comprises hydrovalve 5 and accumulator 6, such rotation driver part is oil hydraulic motor 3, oil hydraulic motor 3 connects accumulator 6 by hydrovalve 5, and accumulator 6 also connects the main pump 7 driving the second gear 2 in fracturing pump.
When fracturing pump is started shooting, main pump 7 is opened, and drives the second gear 2 to rotate by underground, and main pump 7 also can to energy accumulation in accumulator 6 simultaneously; When needing maintenance after a shutdown, without the need to ato unit, control accumulator 6 outputting power by hydrovalve 5 and drive the first gear 1 and the second gear 2 to rotate, and then adjustment plunger position, complete maintenance.This hydrovalve 5 can be multiple can energy threshold and combination, be preferably two position two-way valve, can realize conducting and cut-off two states, when it switches on state, hydraulic oil flows to oil hydraulic motor 3 from accumulator 6, and then makes it rotate.
In addition, also can be provided with one-way valve 8 between main pump 7 and accumulator 6, the import of one-way valve 8 connects main pump 7.Hydraulic oil is unidirectional flows to accumulator 6 from main pump 7, can to its topping up pressurize.In order to carry out the maintenance of hydraulic system, also can also be provided with stop valve 9 between accumulator 6 and hydraulic oil container, when this stop valve 9 is opened, the hydraulic oil in accumulator 6 flows to hydraulic oil container, to discharge its internal pressure.
It should be noted that, for the hydraulically powered plunger position regulating device shown in Fig. 2, the second gear 2 can arrange independent driver part, also can with the first gear 1 common drive parts, the utility model is not limited to this.As long as when fracturing pump is shut down, rotation driving part rotating drive first gear 1 can be made, and then the extended position of adjustment plunger, technique effect of the present utility model can be realized.
Except the plunger position regulating device of previous embodiment, the invention also discloses a kind of fracturing pump being provided with aforementioned plunger position regulating device, other structure such as structure such as plunger, motor of this fracturing pump with reference to technology that is existing and that improve, can not repeat this herein.
