Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
In the present invention, term " first ", " second " are mainly used for distinguishing different components, but are not limited specifically component
System.Booting of the invention signified refers to the state of the engine of starting fracturing pump, and when shutdown refers to the engine without starting fracturing pump
State.
It is the structural schematic diagram of the pressure break pump plunger position adjustment device of one embodiment of the invention, the embodiment shown in Fig. 1
Structure be used to adjust the position of plunger when fracturing pump is shut down, and then realize the maintenance replacement of plunger and sealing element.Fig. 1 institute
Show and includes at least first gear 1 and rotation driving part in embodiment.
First gear 1 is used to engage with the second gear 2 for connecting crankshaft on fracturing pump.The second gear 2 is in fracturing pump
Existing structure, is generally fixedly connected with crankshaft.It may be provided with connecting rod on crankshaft, crankshaft drives connecting rod crosshead, plunger
Acting, the specific structure of each section can refer to existing and improved technology.The second gear 2 is generally also canine tooth in fracturing pump
Wheel, the preferably number of teeth of first gear 1 are less than the number of teeth of second gear 2, i.e. first gear 1 is pinion gear.
It should be clear that the driving method of gear wheel generally has two kinds in fracturing pump: one is machine driving, engines
Shaft coupling is arrived again to gearbox, then the input gear axle of gear wheel is connected by spline；Another kind is hydraulic drive, engine band
Hydrodynamic press pump, hydraulic pump drive hydraulic motor, and hydraulic motor connects the input gear axle for driving gear wheel by spline.Certainly,
Also other possible driving methods be can have, technical solution is suitable for the invention.
Rotation driving part connects the input shaft of first gear 1, which can rotate when fracturing pump is shut down.
The rotation driving part is preferably independently of the structure except existing drive system.The rotation driving part overhauls more for plunger
Position adjustment when changing, is rotated, and then make second gear 2 and crank rotation by driving first gear 1, to adjust as needed
Whole plunger extended position.
Aforementioned entire position adjustment is not necessarily to start the engine of fracturing pump, and do not need manpower rotate gear or
Shaft coupling is agitated, it is easy to operate, and labor intensity can be reduced, improve working efficiency.In addition, the embodiment also has structure simple
It is single, it is easily fabricated, the advantages of implementation is strong etc..
In the embodiment shown in fig. 1, rotation driving part is hydraulic motor 3, and hydraulic motor 3 connects hydraulic pump 4, passes through
The mode of hydraulic-driven realizes the adjustment of plunger position.Hydraulic pump 4 can be a variety of possible structures, as an implementation, liquid
Press pump 4 is electrodynamic pump, the input shaft of the output axis connection hydraulic motor 3 of the electrodynamic pump；As another embodiment, hydraulic pump
4 be manual pump, the input shaft of the output axis connection hydraulic motor 3 of the manual pump.
Other than hydraulic-driven, mechanical drive mode is can also be used when adjusting in plunger position, and preferably rotation driving part is
Motor, the input shaft of the output axis connection first gear 1 of motor, equally can be realized technical effect of the invention.
For having the structure of hydraulic system in fracturing pump, such rotation driving part can pass through the route in hydraulic system
Its rotation when fracturing pump is shut down is realized in transformation.It is the pressure break pump plunger position adjustment of another embodiment of the present invention shown in Fig. 2
The structural schematic diagram of device, the embodiment include at least hydraulic valve 5 and accumulator 6, and such rotation driving part is hydraulic motor
3, hydraulic motor 3 connects accumulator 6 by hydraulic valve 5, and accumulator 6 is also connected with the main pump 7 that second gear 2 is driven in fracturing pump.
In fracturing pump booting, main pump 7 is opened, and drives second gear 2 to rotate by underground, while main pump 7 may be used also
The energy accumulation into accumulator 6；When needing to overhaul after a shutdown, without starting engine, accumulator 6 is controlled by hydraulic valve 5
Output power drives first gear 1 and second gear 2 to rotate, and then adjusts plunger position, completes maintenance.The hydraulic valve 5 can be with
For it is a variety of can energy threshold and combination, preferably two position two-way valve, it can be achieved that two states of on and off, when it is switched to conducting shape
When state, hydraulic oil flows to hydraulic motor 3 from accumulator 6, and then makes its rotation.
In addition, can also be provided with check valve 8 between main pump 7 and accumulator 6, the import of check valve 8 connects main pump 7.Liquid
Pressure oil unidirectionally flows to accumulator 6 from main pump 7, can be to its filling liquid pressure maintaining.It, can also be in accumulation of energy in order to carry out the maintenance of hydraulic system
Shut-off valve 9 is additionally provided between device 6 and hydraulic oil container, when which opens, the hydraulic oil in accumulator 6 flows to hydraulic oil
Case, to discharge its internal pressure.
It should be noted that second gear 2 can for the plunger position of hydraulic-driven shown in Fig. 2 adjusts device
Individual driving part is arranged, this can also be not limited to 1 common drive component of first gear, the present invention.As long as energy
When fracturing pump is shut down, so that rotation driving part rotate driving first gear 1, and then adjust the extended position of plunger
Realize technical effect of the invention.
Other than the plunger position of previous embodiment adjusts device, the invention also discloses one kind to be provided with aforementioned plunger position
The fracturing pump of adjustment device is set, the structures such as other structures of the fracturing pump such as plunger, engine can refer to existing and improved skill
Art, herein to this without repeating.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
