Part and processing expression and description.
It is shown in Figure 1, it is the one of the opportunity of combat internal weapon bays hatch door transient state actuating system based on fixed displacement motor principle of the present invention
Plant the structure chart of embodiment.
In the present embodiment, the opportunity of combat internal weapon bays hatch door transient state actuating system based on fixed displacement motor principle includes input motor
1st, hydraulic pump 2, accumulator 4 and control valve 5.Herein, input motor 1 for example can be fixed displacement motor.
Wherein, input motor 1 is connected with hydraulic pump 2, for driving hydraulic pump 2.
In some optional implementations, input motor 1 includes oil inlet, oil-out and output shaft.Input motor 1
The high pressure fuel source that oil inlet may be connected in airborne hydraulic systems, the oil-out of input motor 1 may be connected to airborne hydraulic systems
In fuel tank, and the output shaft for inputting motor 1 can be connected with hydraulic pump 2, for the output kinetic energy of hydraulic pump 2, and then be driven
Hydraulic pump 2 is moved (for example, rotation).
Hydraulic pump 2 includes oil-out and oil inlet, and oil-out is connected with the first input end of control valve 5, oil inlet and control
The second input connection of valve 5 processed；
Accumulator 4 is connected on the oil circuit between oil-out and first input end.
When the pressure difference between first input end and the second input is more than a predetermined value, control valve 5 is opened.
In one embodiment, the discharge capacity of input motor 1 is more than the discharge capacity of hydraulic pump 2.
In some optional implementations, the opportunity of combat internal weapon bays hatch door transient state start of the invention based on fixed displacement motor principle
System also includes the check valve 3 being connected between the oil-out of accumulator 4 and hydraulic pump 2.Check valve 3 is used to prevent accumulator 4
In fluid enter hydraulic pump 2 in.
The opportunity of combat internal weapon bays hatch door transient state actuating system based on fixed displacement motor principle of present embodiment also includes being connected to control
Hatch door hydraulic motor 6 between the first output end and the second output end of valve 5 processed.Hatch door hydraulic motor 6 is used to be based on control valve 5
The first output end and the second output end output hydraulic pressure to hatch door perform open and/or closing motion.
The opportunity of combat internal weapon bays hatch door transient state actuating system based on fixed displacement motor principle of present embodiment operationally, can be divided into
Two stages of Energy Accumulator in Plenum Process and hatch door start process.
In the Plenum Process of accumulator 4, control valve 5 is in oil circuit, the hydraulic oil of airborne hydraulic systems before and after middle position, cut-off
Driving input motor 1 is rotated, and the discharge capacity of hydraulic pump 2 is more than due to inputting the discharge capacity of motor 1, and input motor 1 can drive hydraulic pump 2
Fluid is exported to accumulator 4.Accumulator 4 can also increase with the increase pressure of internal fluid.In addition, check valve 3 can be prevented
Fluid in accumulator 4 flows backward to hydraulic pump 2, causes the reversion of hydraulic pump 2.
In the Plenum Process, the hatch door being connected with hatch door hydraulic motor 6 is in the state for turning off or on completion, due to
Control valve 5 is closed during being somebody's turn to do, the oil circuit and hatch door hydraulic motor being connected with the first output end and the second output end of control valve 5
6 in treating work state.
After accumulator 4 completes pressurising, hatch door start process is entered.Now, the accumulation of energy of accumulator 4 is completed, fluid pressure
Reach setting value.Control valve 5 is opened, and hydraulic pump 2 and accumulator 4 are simultaneously the fuel feeding of hatch door hydraulic motor 6, hatch door hydraulic motor 6
Rotate.
In some optional implementations, control valve 5 can be servo valve.In these optional implementations, control
Valve processed can also include control in addition to including first input end, the second input, the first output end and the second output end
End.Control end can receive external control instruction, and change the working condition of control valve 5 based on external control instruction.For example,
External control instruction can make control valve be in middle position so that first input end, the second input and the first output end, second defeated
Go out end not connect, so as to separate oil circuit.Or, external control instruction can control to make the first input end of control valve 5 with its
One output end is connected, and the second input is connected with the second output end, or, external control instruction can also control to make control valve
5 first input end is connected with its second output end, and the second input is connected with the first output end.Two kinds of control valve 5 are opened
The mode of opening correspond to two kinds of oil communication modes, and two opposite directions of motion of open and close of hatch door are correspond to respectively, control
Oil circuit before and after the unlatching of valve 5 processed is connected, hatch door hydraulic motor 6, which is rotated, drives hatch door execution to be turned on or off action.
Using the opportunity of combat internal weapon bays hatch door transient state actuating system based on fixed displacement motor principle of the present invention, have the advantage that：
The effect of energy is stored using accumulator, system is realized under small power input by the opening and closing of control valve and completes
High-power output.The output requirement of the big driving power of bay door system is met, the installed power of system can be reduced again, so as to reduce
The installed power of airborne hydraulic systems.
Input booster mechanism that motor 1 and hydraulic pump 2 constitute can by the boost in pressure of airborne hydraulic systems, so as to
Higher pressure drives hatch door hydraulic motor.Under high pressure, discharge capacity can be smaller needed for hatch door hydraulic motor, volume and again
Amount can be reduced.The volume weight of accumulator 4 can also decline, and the volume weight of whole system will decline therewith.
