Description of drawings
Fig. 1 is a kind of schematic representation of apparatus of collecting hydraulic system overflow energy of the present invention.
Embodiment
Provide a kind of embodiment of collecting the device of hydraulic system overflow energy of the present invention below in conjunction with accompanying drawing.
Fig. 1 is a kind of schematic representation of apparatus of collecting hydraulic system overflow energy of the present invention, sees also shown in Figure 1.A kind of device of collecting hydraulic system overflow energy of the present invention comprises the work system of being made up of relief valve 6, and a sequence valve 5 and an accumulator 13 are installed before the relief valve 6 in work system, makes relief valve 6 can be positioned at the outlet port of accumulator 13.Through sequence valve 5 hydraulic oil is entered to accumulator 13 and carry out accumulation of energy,, avoid the loss of energy with the energy of recycling system.
The present invention also has following mode of execution on the basis of the above:
Please continue referring to shown in Figure 1.Also include pressure transducer 4 in this work system; When accumulator 13 pressure reach predetermined range; Pressure transducer 4 sends signal to control system, and the notice control system can supply hydraulic fluid, and makes accumulator 13 pressure come back to work system through the mode of automatically controlled or hydraulic control.
In the further embodiment of the present invention, above-mentioned pressure transducer 4 also can adopt pressure relay, but accumulator 13 pressure can make accumulator 13 pressure again through the mode of automatically controlled or hydraulic control when reaching predetermined range
Come back to work system.
In the further embodiment of the present invention, relief valve 6 is positioned at the outlet port of accumulator 13, and when accumulator 13 pressure reached the pressure of relief valve 6, work system fluid flowed back to oil sump tank through relief valve 6, protected the working pressure of accumulator 13 and work system effectively.
In the further embodiment of the present invention, the big cartridge valve of flow 10 is installed also in work system, controls, to guarantee that accumulator 13 fluid can be fast to the work system supply hydraulic fluid through the fluid of 10 pairs of work systems of cartridge valve.
In the further embodiment of the present invention, have a hydraulic control valve 7, through using the combination of hydraulic control valve 7 and automatically controlled directional control valve, the unlatching that comes simple and easy control cartridge valve 10 has not only guaranteed the flexibility of control performance, and has guaranteed the Security of control performance.
In the further embodiment of the present invention; Have a shuttle valve 8 and an one-way valve 11; Quote the oil inlet and outlet of cartridge valve 10 through the combination of using shuttle valve 8 and one-way valve 11; And control the unlatching of cartridge valve 10 jointly through the guide oil of system, and making that cartridge valve 10 oppositely can not pressurising, system can normally use safely when guaranteeing accumulator 13 fuel feeding effectively.
Among the further embodiment of the present invention, work system also includes sensor 15 and sensor 16, confirms that according to the pressure of sensor 15, sensor 16 and the Placement and the operating grip of device work system is to the equipment fuel feeding.
The present invention also has the following method of operation on the basis of the above:
When not using this device; Solenoid valve 1 not electric (default conditions); Relief valve 6 limits the Maximum operating pressure of system, and when system works pressure arrived the setting pressure of relief valve 6, relief valve 6 was opened; Hydraulic oil is got back to fuel tank from relief valve 6, and oil-way system and the original system that constitute this moment are as broad as long.
When using this device; It is electric that solenoid valve 1 is got, and when system works pressure reached the cracking pressure of sequence valve 5, sequence valve 5 was opened; The hydraulic oil that sequence valve 5 comes out enters into accumulator 13 through one-way valve 12 and carries out accumulation of energy; When the pressure of accumulator 13 reached the predetermined range value, pressure transducer 4 was posted a letter to control system, and the notice control system can use this device to system supply hydraulic oil.When after the pressure of accumulator 13 reaches the predetermined range value, not being used, energy storage pressure further rises, and when reaching the setting pressure of relief valve 3, relief valve 3 is opened, and hydraulic oil is got back to fuel tank from relief valve 3, and system works pressure is identical with accumulator.
Receive permission when system and use this device behind system supply hydraulic oil that this device can simultaneously, be confirmed to system and equipment fuel feeding according to pressure of this device Placement and operating grip and sensor 15,16 to system supply hydraulic oil.When solenoid valve 2 electric, the position work of solenoid valve 2 left side, control oil arrives the control mouth of hydraulic control valve switching-over 7, makes the hydraulic control valve 7 the next work that commutate.Through the control of shuttle valve 8, this moment if the pressure of the B mouth of cartridge valve 10 greater than the pressure of A mouth, then the B mouth is to the conducting of A mouth; Otherwise then the B mouth is to the not conducting of A mouth, and the A mouth is to the also not conducting of B mouth.The effect of shuttle valve 8 and one-way valve 11 is that the highest control hydraulic oil of obtaining cartridge valve 10 both sides is controlled cartridge valve; The effect of one-way valve 9 is when preventing just to start the machine; In the accumulator not build-up pressure cause cartridge valve 10 not have the control oil pressure, make work system oppositely through cartridge valve A mouth to the B mouth to the accumulator pressurising.
When temporarily not using this device, solenoid valve 1 outage when not using this device for a long time, is opened the pressure oil that needle-valve 14 releases accumulator.In this device, the pressure that relief valve 3 is set must be less than the setting pressure of relief valve 6, and the setting pressure of sequence valve 5 should be equal to or slightly less than the setting pressure of relief valve 3, the accumulation of energy DeGrain.
In sum; Use a kind of device of collecting hydraulic system overflow energy of the present invention; When energy storage pressure reached predetermined range, sequence valve carried out accumulation of energy to accumulator, and made energy storage pressure oil come back to work system through automatically controlled or hydraulic control mode; Not only avoid the loss of energy and original paper, and can improve equipment operating rate and efficient.
The above is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
