Hydraulic-driven power, the oil return of hydraulic cylinder return to pumping plant oil return opening through fluid pressure line, fuel tank are returned after return filter.Work as hydraulic pressure
When power is applied on hook machine or excavator, because the equipment is not continuously externally to do work at work, its output work
Rate is discontinuously to export, so the constant hydraulic power of its hydro-power pump output just can not all be efficiently applied to the hook machine
Or in the external acting of excavator, when hook machine pauses or do not done work, its hydraulic pressure persistently exported can only all flog a dead horse, finally
Fuel tank is returned, can not efficiently utilize the external caused high hydraulic pressure kinetic energy of hydro-power pump.
The content of the invention
Disclosed by the invention is a kind of efficient hydraulic power unit, and its main purpose is to overcome existing for prior art
Above-mentioned deficiency and shortcoming, there is provided a kind of hydraulic power unit, it can not only effectively utilize what hydro-power pump outwards exported
High hydraulic pressure kinetic energy, and the apparatus structure is simply exquisite, it is workable.
The technical solution adopted by the present invention is as follows：
A kind of efficient hydraulic power unit, including one be used for provide high-pressure and hydraulic oil body oil pump body, one be used for store
The storage piston cavity of hydraulic oil and a hydraulic oil work done output end, the oil pump body lead to respectively with hydraulic oil work done output end
An oil circuit is crossed with the storage piston cavity to be connected setting.
Further, the storage piston cavity includes a storage chamber, coordinates plug to be provided with one in the storage chamber removable
Dynamic piston body, the piston body offset with one for limiting the limit damper that the piston body moves from minimum point to peak
Connect setting.
Further, it is equipped with an emptying valve body above the side wall of the storage chamber.
Further, when the piston body is moved to its peak, the emptying valve body is opened, and makes the storage chamber
Interior hydraulic oil is drawn off.
Further, the limit damper includes several buffer air bag bodies and one for providing fluid pressure source
Fluid pressure cavity, the pressure output end of the fluid pressure cavity are connected setting with the pressure input of the buffer air bag body, institute
The clutch end and the piston body for stating buffer air bag body abut against setting.
Further, the fluid pressure cavity is a liquid tank for being used to contain liquid.
Further, the fluid pressure cavity is a sealing air pressure tank for being used to deposit gas.
By the above-mentioned description of this invention, compared to the prior art, the advantage of the invention is that：
The present invention makes high hydraulic pressure kinetic energy that oil pump body inputs can be with by setting storage piston cavity and limit damper
All stored when acting is not done work or reduced to hydraulic oil work done output end, then constantly externally output again, makes high pressure
Hydraulic pressure kinetic energy can extremely efficiently be used, avoid oil pump body from externally flogging a dead horse；At the same time it can also by reducing oil
The power that the pump housing externally exports, then kinetic energy be present using the storage piston cavity jointly and externally carry out constantly output acting,
Not only make power output obtain further efficiently utilizing, and oil pump body can be made to reduce external high-power output, raising is set
Standby service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Structural representation when Fig. 2 is present invention work.
Embodiment
Illustrate with reference to the accompanying drawings further to illustrate the embodiment of the present invention.
As shown in Figures 1 and 2, a kind of efficient hydraulic power unit, including one be used to provide the oil of high-pressure and hydraulic oil body
The pump housing 1, one is used for the hydraulic oil work done output end 3 of storage piston cavity 2 and one for storing hydraulic oil, the oil pump body 1 and liquid
Force feed work done output end 3 is connected setting by an oil circuit 4 with the piston cavity 2 that stores respectively.The storage piston cavity 2
Plug is coordinated to be provided with a moveable piston body 22 including a storage chamber 21, in the storage chamber 21, the piston body 22 and one is used
Setting is abutted against in limiting the limit damper 5 that the piston body 22 moves from minimum point to peak.
As shown in Figures 1 and 2, an emptying valve body 23, the piston body are equipped with above the side wall of the storage chamber 21
22 when being moved to its peak, and the emptying valve body 23 is opened, and draws off the hydraulic oil in the storage chamber 21.The limit
Bit buffering device 5 includes the fluid pressure cavity 52 that several buffer air bag bodies 51 and one are used to provide fluid pressure source, the fluid
The pressure output end of pressure chamber 52 is connected setting with the pressure input of the buffer air bag body 51, the buffer air bag body 51
Clutch end setting is abutted against with the piston body 22 by a connecting rod 53.The fluid pressure cavity 52 is one for containing
The liquid tank or a sealing air pressure tank for depositing gas of liquid are filled, by the pressure for adjusting the fluid in liquid tank or air pressure tank
Power controls the pressure output of the limit damper 5.
The course of work of the present invention：High pressure is continuously added into the storage piston cavity by the oil pump body first
Hydraulic oil, that is, high pressure kinetic energy is provided, while the oil pump body constantly externally does work, the hydraulic oil work done output end is in the high liquid
Press and externally do work in the presence of energy, when the hydraulic oil work done output end reduces or suspends externally acting, the oil pump body
The high pressure liquid force feed persistently inputted will be temporarily stored within the storage chamber, and the piston body is active in the high hydraulic pressure of input
In the presence of move up, meanwhile, the limit damper provides down force and keeps pressure in the storage chamber
Value, the upward buffer compression of buffer air bag body；When the hydraulic oil work done output end restarts externally to do work, described slow
In the presence of qi of chong channel ascending adversely utricule, the piston body moves down, and the high pressure liquid in the storage chamber is pressed oil and the oil pump
The high-pressure and hydraulic oil body that body provides outwards exports high pressure kinetic energy simultaneously.And when the high pressure kinetic energy that the oil pump body persistently inputs exceedes
During the limit of storage chamber, the piston body is moved to its extreme higher position, and at this moment, the emptying valve body is opened, and it is unnecessary to draw off
High pressure kinetic energy.
The present invention makes the hydraulic pressure kinetic energy of the high pressure of oil pump body input by setting storage piston cavity and limit damper
Can all it be stored when acting is not done work or reduced to hydraulic oil work done output end, then constantly externally output again, makes
The hydraulic pressure kinetic energy of high pressure can be used extremely efficiently, avoid oil pump body from externally flogging a dead horse；At the same time it can also pass through drop
The power that low oil pump body externally exports, then kinetic energy be present using the storage piston cavity jointly and externally carry out constantly exporting doing
Work(, not only make power output obtain further efficiently utilizing, and oil pump body can be made to reduce external high-power output, improve
The service life of equipment.
The embodiment of the present invention is above are only, but the design concept of the present invention is not limited merely to this, every profit
The present invention is improved with carrying out unsubstantiality with this design, should belong to the behavior for invading the scope of the present invention.
