Abstract
The invention discloses a rapid pressurization system of a hydraulic energy accumulator. The rapid pressurization system comprises an oil pump, the energy accumulator, an oil cylinder, a pressure switch, a hydraulic control check valve, an electromagnetic valve, a check valve, an unloading valve and a direction valve. The unloading valve, the check valve, the electromagnetic valve and the hydraulic control check valve are sequentially arranged between the oil pump and the energy accumulator. The unloading valve, the check valve and the pressure switch are sequentially arranged between the oil pump and the oil cylinder. A motor with the small oil pump is adopted, no motors with high pressure oil pumps are arranged independently, only a valve set is arranged between the system and the energy accumulator, and therefore the requirement for increasing the pressure to set pressure within a short period of time after large-flow work is met. The rapid pressurization system is simple in structure, convenient to operate, high in practicability, capable of saving energy and low in heat dissipation performance.
Description
Technical field
The present invention relates to the hydraulic system with accumulator, particularly a kind of hydraulic accumulator quick pressurization system.
Background technique
Hydraulic system purposes with accumulator is very extensive, has use in the place of a lot of hydraulic actuator intermittens.Its principle is to utilize the less power such as oil pump, motor, in hydraulic actuator standby, in accumulator, pump into high pressure oil, utilize the elasticity of accumulator gas, energy storage is got up, when action Deng hydraulic actuator, the oil extraction simultaneously of oil pump and accumulator, can meet actuator's short time high speed operation.Its advantage is: 1. can use the oil pump less than normal configuration and motor, energy saving, reduce Oil pump electrical machinery noise; 2. can moment super-flow, make up the unappeasable operating mode of Oil pump electrical machinery.
Accumulator is divided into G&O two-part, and the increase of its pressure is in accumulator, to pump into hydraulic oil by oil pump, thereby pressurized gas boosts gradually.To need the corresponding pump oil time but the oil pump of small displacement will be elevated to the pressure of the accumulator of large volume certain value, if while needing the short time to be pressurized to specified pressure after large flow work, conventional accumulator scheme just can not meet.Method has two at present: 1. and according to the pressure maximum of work requirements and flow configuration oil pump and motor, not energy-conservation but the method exists, the serious defect of generating heat; 2. also adopt accumulator scheme, join separately a set of high pressure oil pump motor and control valve member, after waiting and move, start the supercharging of high pressure oil pump motor, but also there is high, the baroque defect of cost in the method while.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of hydraulic accumulator quick pressurization system is provided, reach and use little Oil pump electrical machinery to meet the advantage that hydraulic system accumulator loop moment after large flow work is added to high pressure.
For achieving the above object, the designed a kind of hydraulic accumulator quick pressurization system of the present invention, comprises oil pump, accumulator, oil cylinder and pressure switch; Pilot operated check valve, solenoid valve, one-way valve, unloading valve and directional control valve; Unloading valve, one-way valve, solenoid valve and Pilot operated check valve are installed successively between oil pump and accumulator, unloading valve, one-way valve and pressure switch are installed successively between oil pump and oil cylinder.
Further, described unloading valve is arranged on the two ends of one-way valve.
Further, described solenoid valve is arranged on the two ends of Pilot operated check valve, as the switch for controlling Pilot operated check valve.
The invention has the advantages that:
1, the present invention adopts little Oil pump electrical machinery, does not configure separately high pressure oil pump motor, and a sleeving valve group is only set between system and accumulator, has solved after large flow work and has needed the short time to be pressurized to the requirement of specified pressure.
2, the present invention is simple in structure, easy to operate, has very strong practicability, and energy-conservation, heating value is little.
Brief description of the drawings
Fig. 1 is hydraulic accumulator quick pressurization system figure of the present invention
In figure, 1. Pilot operated check valve, 2. solenoid valve, 3. oil pump, 4. one-way valve, 5. unloading valve, 6. accumulator, 7. directional control valve, 8. oil cylinder, 9. pressure switch.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, so that those skilled in the art understand.
Embodiment 1
A kind of hydraulic accumulator quick pressurization system shown in figure, comprising: oil pump, accumulator, oil cylinder and pressure switch; Pilot operated check valve 1, solenoid valve 2, one-way valve 4, unloading valve 5 and directional control valve 7; Unloading valve 5, one-way valve 4, solenoid valve 2 and Pilot operated check valve 1 are installed successively between oil pump 3 and accumulator 6, unloading valve 5, one-way valve 4 and pressure switch 9 are installed successively between oil pump 3 and oil cylinder 8.Described unloading valve 5 is arranged on the two ends of one-way valve 4.
Described solenoid valve 2 is arranged on the two ends of Pilot operated check valve 1, as the switch for controlling Pilot operated check valve 1.
Working principle:
The pressure oil that oil pump 3 pumps arrives the B end of Pilot operated check valve 1 through one-way valve 4, arrive the control mouth of Pilot operated check valve 1 through directional control valve 2, opens Pilot operated check valve 1, and pressure oil is from the B of Pilot operated check valve 1 to A, and turn-on accumulator 6, rushes liquid toward accumulator.In the time that oil cylinder 8 moves, make solenoid valve 7 obtain electric commutation, oil pump, accumulator fuel feeding simultaneously, large flow impels oil cylinder to move fast, and accumulator internal pressure is also in rapid decline simultaneously.In the time that oil cylinder 8 contact loads need pressurization rapidly, solenoid valve 2 obtains electric, B end pressure oil cuts off with the control oil of Pilot operated check valve 1, the release of control port simultaneously, the B to A of Pilot operated check valve 1 is closed, the pressure oil that oil pump 3 pumps is blocked by Pilot operated check valve 1, avoids accumulator 6, directly oil cylinder 8 is pressurizeed.In the time arriving setting pressure, pressure switch 9 is sent signal, solenoid valve 2 power-off, and oil pump 3 continues toward accumulator 6 repairings.
Although above-described embodiment has been made detailed description to the present invention; but it is only the present invention's part embodiment; instead of whole embodiments, people can also obtain other embodiments according to the present embodiment under without creative prerequisite, and these embodiments belong to protection domain of the present invention.
