Abstract

The present invention relates to an uninterrupted hydraulic source for a hydraulic inductance type deep-sea underwater hydraulic system. An electromagnetic reversing valve and a high-speed hydraulic motor with flywheels are connected to a hydraulic main line oil supply passage in series. A one-way valve is bridged between the hydraulic main line oil supply passage and a hydraulic main line oil returning passage, and the output end of the one-way valve is connected with the output end of the electromagnetic reversing valve and the input end of the high-speed hydraulic motor with the flywheels. When started, the hydraulic source firstly stores energy required by the high-speed hydraulic motor and the flywheels under an emergent condition. When the hydraulic system works normally, the high-speed hydraulic motor and the flywheels can ensure the continuity and the stability of oil supply flow. During the rapid decompression of the hydraulic source, the electromagnetic reversing valve is cut off, and the hydraulic source is isolated from the upstream of the high-speed hydraulic motor; at the same time, due to the large inertia of the flywheels, the flow passing through the high-speed hydraulic motor can not change abruptly; therefore, considerable flow still passes through the hydraulic motor towards loads and releases stored energy for the hydraulic system to finish all necessary hydraulic emergence action; and the flow is irrelevant to the depth of water where the hydraulic system is positioned.

Description

Uniterrupted hydraulic source for liquid-sensing deep sea hydraulic system
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 Uniterrupted hydraulic source for liquid-sensing deep sea hydraulic system, lose the power source at the deep-sea under water, lose and still can finish all essential hydraulic emergencies actions under the situation of whole power supplies even.
The technical solution used in the present invention is: it comprises high-speed hydraulic motor, the one-way valve of solenoid directional control valve, band flywheel; The high-speed hydraulic motor of solenoid directional control valve and band flywheel is serially connected on the hydraulic bus fuel feeding road, one-way valve is connected across between hydraulic bus fuel feeding road and hydraulic bus oil circuit, and the output terminal of one-way valve is connected with the input end of the high-speed hydraulic motor of the output terminal of solenoid directional control valve, band flywheel.
The beneficial effect that the present invention has is: during the hydraulic power starting, at first be high-speed hydraulic motor and flywheel, store energy needed under the case of emergency.During the hydraulic system proper functioning, high-speed hydraulic motor and flywheel can be guaranteed the continuity and the stationarity of fuel supply flow rate.During the hydraulic power rapid decompression, solenoid directional control valve cuts off, and hydraulic power and high-speed hydraulic motor upstream are isolated; Meanwhile, because the big inertia of flywheel, the flow by high-speed hydraulic motor can not suddenly change, thereby still has suitable flow to flow to load by oil hydraulic motor, discharges stored energy, and the feed flow pressing system is finished all essential hydraulic emergencies actions; The residing depth of water of this flow and hydraulic system is irrelevant.
Description of drawings
Accompanying drawing is a structural principle schematic representation of the present invention.
Embodiment
As shown in drawings, it comprises high-speed hydraulic motor 2, the one-way valve 3 of solenoid directional control valve 1, band flywheel; The high-speed hydraulic motor 2 of solenoid directional control valve 1 and band flywheel is serially connected on the hydraulic bus fuel feeding road A, one-way valve 3 is connected across between hydraulic bus fuel feeding road A and hydraulic bus oil circuit B, and the input end of the high-speed hydraulic motor 2 of the output terminal of the output terminal of one-way valve 3 and solenoid directional control valve 1, band flywheel is connected.
T represents the return pressure of self adaption fuel tank among the figure, and this pressure equates with the pressure of extraneous seawater; P represents the delivery pressure of this hydraulic power, the output pressure reduction that its absolute value equals hydraulic power add extraneous hydraulic pressure and;
p 1The pressure of expression high-speed hydraulic motor input end, this pressure equals the delivery pressure p of hydraulic power when solenoid directional control valve is switched on, then equal the return pressure T of self adaption fuel tank when solenoid directional control valve cuts off the power supply; Enough for guaranteeing the flywheel energy stored, require the output flow substantially constant of hydraulic power, or require the minimum energy storage limit of load flow greater than flywheel.
Working procedure: during the hydraulic power starting, at first be high-speed hydraulic motor and flywheel 2, store energy needed under the case of emergency.During the hydraulic system proper functioning, high-speed hydraulic motor and flywheel 2 can be guaranteed the continuity and the stationarity of fuel supply flow rate.During the hydraulic power rapid decompression, solenoid directional control valve 1 cuts off, and hydraulic power and high-speed hydraulic motor 2 upstreams are isolated; Meanwhile, because the big inertia of flywheel, the flow by high-speed hydraulic motor can not suddenly change, thereby still has suitable flow to flow to load by oil hydraulic motor, discharges stored energy, and the feed flow pressing system is finished all essential hydraulic emergencies actions; In addition, owing to flow into p 1The flow of cavity volume is less than the flow that flows out, p 1Pressure descends and opens under the effect of self adaption tank drainback pressure up to one-way valve 3, replenishes the flow that flows to high-speed motor.High-speed hydraulic motor is decrescence fast under the effect of load, up to having discharged all energy stored.
Specific embodiment: for uninterrupted hydraulic power as shown in drawings, the A2F12R6.1 inclined plunger hydraulic pump/motor that can adopt Shanghai Hydraulic Pump Factory to produce, under the enough operating mode of this class return oil pressure of deep-sea underwater hydraulic system, its maximum speed can reach 6000rpm, if selecting discharge capacity for use is the motor of 12ml/r, the boundary dimension of flywheel is got φ 240 * 100, and its rotary inertia is 0.25kgm 2, under the induced pressure of 10MPa, can discharge 4.9 liters hydraulic oil at most.And the residing depth of water of this flow and hydraulic system is irrelevant.
