Specific embodiment
Specific embodiment of the utility model is elaborated below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes the air compressor machine, air cushioning tank and the nitrogen making machine that are sequentially connected in series；It is described
The output end of nitrogen making machine connects nitrogen air accumulator by check valve, and the nitrogen air accumulator connection measures the pressure of its internal pressure
Transmitter, the pressure transmitter connects air inlet electromagnetic valve, and the output end of the air inlet electromagnetic valve connects the air inlet of vacuum tank
And vacuum orifice, the air inlet and vacuum orifice are while connect the vacuum extractor and manual pressure release valve of vacuum tank；The control
The control signal of system processed connects the pressure sensor of vacuum tank and the pressure transmitter of nitrogen pot, the control system respectively
Output end connect the vacuum extractor and air inlet electromagnetic valve of vacuum tank respectively.
The vacuum tank is made up of airtight building enclosure and gas-tight door, the vacuum tank internally provided with vacuum pump and vacuometer.
Embodiment one：Control manually
Opening air compressor machine, air cushioning tank, nitrogen making machine respectively carries out high-purity nitrogen, treats that the purity of nitrogen is conformed to
Nitrogen air accumulator is inflated when asking.The manual interface of opening control, selection control manually.Open vacuum extractor,
System is vacuumized to vacuum tank automatically, when the pressure of vacuum tank reaches necessary requirement, closes vacuum extractor, vacuum tank
Maintain vacuum state now.The air inlet electromagnetic valve button at manual interface is opened, air inlet electromagnetic valve is opened, and system is automatically to vacuum
Cabinet carries out inflated with nitrogen, when vacuum tank output pressure signal meets the requirements, closes air inlet electromagnetic valve, and vacuum tank maintains now true
Dummy status, is repeated several times said process until oxygen content state less than needed in vacuum tank.
Embodiment two：Automatically control
Opening air compressor machine, air cushioning tank, nitrogen making machine respectively carries out high-purity nitrogen, treats that the purity of nitrogen is conformed to
Nitrogen air accumulator is inflated when asking.The automatic interface of opening control, selection is automatically controlled.True is taken out to vacuum tank input
The minimum pressure of space-time-aspirator vacuum degree, maximum pressure-nitrogen charging vacuum when being filled with nitrogen, the pressure for maintaining vacuum tank
Residual compression-nitrogen the tank pressure of number of times-cycle-index, nitrogen air accumulator when return difference value-pumping return difference value, each nitrogen charging are vacuumized
The multiple parameters such as power carry out input setting.After set-up of control system parameter, the automatic running of opening control, control system
The state of now vacuum tank is first determined whether, if now the vacuum of vacuum tank is not within return difference value, then system is beaten first
Drive vacuum extractor carries out vacuum pumping to vacuum tank, when the vacuum of vacuum tank reaches the numerical value of aspirator vacuum degree, is
System is automatically switched off vacuum extractor, and then automatically turn on air inlet electromagnetic valve carries out inflated with nitrogen to vacuum tank, when the vacuum of vacuum tank
When degree reaches the numerical value of nitrogen charging vacuum, system is automatically switched off air inlet electromagnetic valve.Then the above-mentioned nitrogen charging of system automatic cycle-take out is true
Null process, the cycle-index until reaching setting.
System judges vacuum tank state when opening automatic running, if now the vacuum of vacuum tank is within return difference value,
So system directly opens air inlet electromagnetic valve and carries out inflated with nitrogen to vacuum tank, and then system is automatically performed above-mentioned nitrogen charging-take out true
Null process, after reaching setting last time cycle-index, system automatically recovers to normal pressure the pressure in cabinet.Due to vacuum
It is negative pressure in cabinet, what the gas in air can be slowly permeates in vacuum tank, treats that the vacuum in cabinet rises to nitrogen charging vacuum
When, system can automatically be again introduced into the process of above-mentioned circulation.After system repeatedly carries out the circulation, the pressure meeting of nitrogen air accumulator
It is reduced to below nitrogen pot pressure set points, in order to prevent nitrogen from exhausting, above-mentioned cyclic process automatically becomes circulation one every time
It is secondary and have alarm in the controls.
When vacuum extractor is vacuumized, when the vacuum of vacuum tank reaches aspirator vacuum to be spent, in order to eliminate buffer system
Have of short duration Delayed shutdown.
Airtight building enclosure includes that the reinforcement being uniformly arranged further enhances the expensive intensity of vacuum.
For avoid rare cultural relics archives etc. because humidity change and caused by damage, humidity control apparatus are also set in vacuum tank.
One embodiment of the present utility model has been described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as limiting practical range of the present utility model.It is all to be made according to present utility model application scope
Impartial change with improve etc., all should still belong within patent covering scope of the present utility model.
