Abstract
The present invention discloses a uninterrupted hydraulic source of liquid volume type deep-sea underwater hydraulic system, which is characterized by that it comprises 1-n energy-storing devices with different precharged pressures which are parallel-connected on the hydraulic source. When the depth of water in which the hydraulic source is positioned in shallower, the energy-storing device with higher precharged pressure doen not work, and the energy-storing device with lower precharged pressure is being in optimum working zone and can release more flow, and when the depth of water in which the hydraulic source is placed is deeper, the energy-storing device with high precharged pressure is being in optimum working zone and can release more flow, so that the proper precharged pressure combination only is selected.
Description
Technical field
The present invention relates to pressurized machine or fluid pressure transducer.
Background technique
The deep-sea underwater hydraulic system generally adopts return pressure and the self balancing self adaption fuel tank of extraneous hydraulic pressure, the output pressure reduction that the absolute value of its delivery pressure equals hydraulic power add extraneous hydraulic pressure and.Therefore, conventional hydraulic is by single accumulator stored energy, provide the method for using under the emergency condition be subjected to the hydraulic power depth of water of living in probabilistic influence serious, almost can't proper functioning.
For example: for an output pressure reduction is the hydraulic system of 10MPa, and having selected a volume for use is 10 liters accumulator.If on the ground, but the pressure of preliminary filling 5Mpa when the hydraulic system rapid decompression, can discharge 3.9 liters hydraulic oil at most.And this accumulator is used for the deep-sea underwater hydraulic system, at least the pressure that needs preliminary filling 20Mpa, it not only under water 1000 meters can't work with interior, releasable flow also becomes very little, (depth of water unit is that rice, flux unit are for rising) as shown in the table more than 1000 meters the time:
| The depth of water of living in | 1500 | ?2000 | ??2500 | ??3000 | ??3500 | ??4000 | ??4500 | ??5000 | ??5500 | ??6000 | ??6500 | ??7000 |
| Can discharge flow | 1.5 | ?1 | ??0.8 | ??0.6 | ??0.5 | ??0.4 | ??0.35 | ??0.3 | ??0.25 | ??0.2 | ??0.2 | ??0.2 |
Therefore, at present the deep-sea underwater hydraulic system all be badly in need of the higher uninterrupted hydraulic pressure of a kind of energy storage efficiency can supplier so that in its source that runs out of steam, lose under the situation of whole power supplies and still can finish all essential hydraulic emergencies actions even.
Summary of the invention
The objective of the invention is to design a kind of Uninterupted hydraulic source for liquid-holding deep sea hydraulic system, the source that runs out of steam under water at the deep-sea, lose and still can finish all essential hydraulic pressure jerking movements under the situation of whole power supplies and do even.
The technical solution used in the present invention is: it comprises that the accumulator parallel connection that is not waited by a plurality of preliminary filling pressure constitutes and is attempted by on the hydraulic power.
The useful effect that the present invention has is: when the residing depth of water of hydraulic power was more shallow, the higher accumulator of preliminary filling pressure was not devoted oneself to work, but the lower accumulator of preliminary filling pressure is in optimum working zone, can discharge more flow; When the residing depth of water of hydraulic power was dark, the accumulator pressurized that preliminary filling pressure is lower was serious, and the flow that can discharge is less, but the higher accumulator of preliminary filling pressure is in optimum working zone, can discharge more flow.Therefore, as long as select suitable preliminary filling pressure combination, regardless of the residing depth of water of hydraulic system, this uninterrupted hydraulic power can discharge more considerable flow, finishes all essential hydraulic emergency actions.

Accompanying drawing is a structural principle schematic representation of the present invention.
Embodiment
As shown in drawings, it comprises the accumulator that is not waited by 1～n preliminary filling pressure, and formation in parallel is attempted by on the hydraulic power A.
N is 2 * (the highest deep sea hydraulic/oil sources delivery pressure is poor)+1 ultrahigh pressure accumulator, volume is all selected maximum more than 2.5 times of flow that discharge, preliminary filling pressure is controlled the accumulator formation in parallel that is spaced apart 1/2 oil sources output pressure reduction successively that first is 1/2 an oil sources output pressure reduction respectively, is attempted by on the hydraulic power A.
P represents the delivery pressure of this hydraulic power among the figure, the output pressure reduction that its absolute value equals hydraulic power add extraneous hydraulic pressure and;

nRepresent the flow that each accumulator can be discharged.
Working procedure: the hydraulic system prestart has had the pressure that equates with extraneous hydraulic pressure in the output oil pipe of hydraulic power.This part pressure at first compresses the accumulator that each preliminary filling pressure is lower than extraneous hydraulic pressure, makes the air bag external and internal pressure weighing apparatus of accumulator.The flow that enters in this process in the accumulator can not use under case of emergency, belongs to invalid traffic.In the process of boosting after the hydraulic system starting, the air bag of accumulator further is compressed, and stores energy needed under the case of emergency.During the hydraulic system proper functioning, each accumulator can be guaranteed the stationarity of charge oil pressure and the continuity of flow.During the hydraulic power rapid decompression, the air bag volume of each accumulator increases, and extrudes the good flow of original storage, thereby still has suitable flux and flow direction load, discharges stored energy, and the feed flow pressing system is finished all essential hydraulic emergency actions.The pressure of accumulator air bag reduces in the flow releasing course gradually, up to having discharged all energy stored.
Specific embodiment: for uninterrupted hydraulic power as shown in Figure 1, for maximum water depth is 6000 meters, oil sources output pressure reduction is 10MPa, maximum release traffic requirement is 4 liters a hydraulic system, can adopt 13 ultrahigh pressure accumulators of producing by Fenghua hydraulic parts factory to be formed in parallel, volume all is chosen as 10 liters, and preliminary filling pressure is controlled to be 5MPa, 10MPa, 15MPa......65MPa respectively, is spaced apart 5MPa (half of working pressure).Releasable flow (depth of water unit is that rice, flux unit are for rising) as shown in the table under the different depth of water:
