Abstract
The utility model discloses an overpressed system of a cubic press, which comprises an axial plunger pump, wherein the axial plunger pump is connected with a pressure increasing valve through a magnetic exchange valve, and the pressure increasing valve is connected with a pressure cavity of the cubic press. A hydraulic system is simplified, the running rate of equipment is improved, the breakdown maintenance frequency is reduced, and the cost is saved.
Description
Technical field
The utility model relates to a kind of cubic hinge press overpressure system.
Background technology
The superpressure mode of existing cubic hinge press is: two super-pressure radial plunger pumps are worked simultaneously during superpressure; Between hold period; Because it is former thereby cause system pressure decline to leak volume contraction when forming with diamond etc. in the system, be that system provides ftercompction by super-pressure radial plunger pump wherein at this moment.Along with the continuous expansion of cubic hinge press synthetic cavity, required synthesis pressure is also increasingly high, and the flow of super-pressure pump and pressure also will improve, and like this or increase the quantity of super-pressure radial plunger pump, or improves the driving power of super-pressure radial plunger pump.The quantity of super-pressure pump increases and can cause the hydraulic system joint many, increases the leakage of oil point, also can cause floor space big.If improve the driving power of super-pressure pump then can make voltage ripple of power network big and influence the quality of diamond synthesis.And the system pressure demand is high more, and the frequency of maintenance of super-pressure radial plunger pump is also high more.
The utility model content
The purpose of the utility model provides cubic hinge press overpressure system a kind of simplification, that operation rate is high.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of cubic hinge press overpressure system comprises axial plunger pump, and axial plunger pump is connected with pressure charging valve through solenoid directional control valve, and pressure charging valve is connected with the cubic hinge press pressure chamber.
Said pressure charging valve comprises the pilot operated valve device that is communicated with solenoid directional control valve, and pilot operated valve device is communicated with pressure charging valve valve body back cavity; Solenoid directional control valve is communicated with pressure charging valve valve body ante-chamber through check valve, and pressure charging valve valve body ante-chamber is communicated with through second check valve with the cubic hinge press pressure chamber.
In the utility model; Through pressure charging valve is set in system; During system overpressure: axial plunger pump directly provided pressure for system when 20MPA was following; Axial plunger pump was that pressure charging valve provides the energy and power when 20MPa was above, and pressure charging valve is through moving back and forth, and the energy and power that plunger displacement pump is provided are converted into the required high pressure of system; The utility model has the advantages that: 1. practice thrift cost; 2. reduce the breakdown maintenance frequency; 3. simplification hydraulic system, the running rate of raising equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; A kind of cubic hinge press overpressure system; Comprise axial plunger pump 5, axial plunger pump 5 is connected with pressure charging valve 6 through solenoid directional control valve 7, and pressure charging valve 6 is connected with cubic hinge press pressure chamber 4; Be provided with check valve 2 between axial plunger pump 5 and the solenoid directional control valve 7, be connected with choke valve 3 on the pipeline between check valve 2 and the solenoid directional control valve 7.Said pressure charging valve 6 comprises the pilot operated valve device 62 that is communicated with solenoid directional control valve 7, and pilot operated valve device 62 is communicated with pressure charging valve valve body 61 back cavities; Solenoid directional control valve 7 is communicated with pressure charging valve valve body 61 ante-chambers through check valve 64, and pressure charging valve valve body 61 ante-chambers are communicated with through second check valve 63 with cubic hinge press pressure chamber 4.
The operation principle of the utility model is: when 20MPa is following, and pilot operated valve device 62 switching-overs, the pressure oil of axial plunger pump 5 directly gets into cubic hinge press back cavity 4 through solenoid directional control valve 7, check valve 64 and second check valve 63; When pressure surpasses 20MPa; Pressure charging valve 6 is started working; The piston of pressure charging valve 6 is given 62 1 signals of pilot operated valve device simultaneously in least significant end at this moment, makes pilot operated valve device 62 switching-overs; At this moment hydraulic oil is through the back cavity of solenoid directional control valve 7 with pilot operated valve device 62 entering pressure charging valve valve bodies 61, and the hydraulic oil of pressure charging valve valve body 61 ante-chambers gets into cubic hinge press pressure chamber 4; When pressure charging valve 6 pistons rise to highest point, give 62 1 signals of pilot operated valve device, make pilot operated valve device 62 switching-overs; Hydraulic oil is through the back cavity of solenoid directional control valve 7 with check valve 64 entering pressure charging valve valve bodies 61, and the piston that promotes pressure charging valve 6 moves down, when the piston of pressure charging valve 6 moves bottom; Repeat above-mentioned action; Realize that the pressure charging valve piston automatically moves back and forth, the back cavity pressure of pressure charging valve valve body 61 raises always, realizes superpressure.
