And open the first control valve 11.
After the first control valve 11 is opened, fluid pressure detection means 3 detects the pressure that battery bag 5 is subject to, fluid pressure
When the detected value of detection means 3 is less than goal pressure, controller 4 accounts for target pressure according to the detected value of fluid pressure detection means 3
The ratio of power adjusts the aperture of the first control valve 11, and fluid pressure detection means 3 records in real time to the pressure that battery bag 5 is subject to,
And feed back on controller 4, the ratio of goal pressure is accounted for according to the detected value of fluid pressure detection means 3, controller 4 is adjusted in real time
The aperture of whole first control valve 11, until the detected value of fluid pressure detection means 3 is equal to goal pressure.
It is when the time of the first timer 61 record exceedes the preset time for meeting preparatory condition, i.e., super during regulation
Preset time is crossed, when can not still meet default regulation, it was demonstrated that the detected value of fluid pressure detection means 3 can not be adjusted to equal to mesh
Pressure is marked, the first warning device 7 is alarmed.
When the detected value of fluid pressure detection means 3 is more than goal pressure and is less than protection pressure, the first control is closed
Valve 11, while the second control valve 12 is opened, the gas in gradual discharge pressure container 2, until the inspection of fluid pressure detection means 3
Measured value is equal to goal pressure.
During regulation, the time of the first timer 61 record is more than reset time, the inspection of fluid pressure detection means 3
When measured value can not be still adjusted to equal to goal pressure, alarming device sends warning, and closes the first control valve 11.
When the detected value of fluid pressure detection means 3 is more than protection pressure, the first control valve 11 is closed, while open the
Two control valves 12, the gas in gradual discharge pressure container 2.Superpressure failure now occurs, the second warning device 8 is alarmed, need to stopped
Only test.
When the detected value of fluid pressure detection means 3 is in target pressure range, the first control valve 11 is closed, is closed simultaneously
Close the second control valve 12.
When the record value of the 3rd timer 63 is more than or equal to soaking time, controller 4 can control the second control valve 12
Open, i.e., fluid pressure detection means 3 is under pressure to battery bag 5 and detected in real time, and battery bag 5 is under the pressure value
When duration is more than or equal to soaking time, the second control valve 12 is opened, the gas in discharge pressure container 2, device standby, from
And complete experiment.
In short, according to the battery bag immersion water test equipment 100 of the present invention, by setting pressure input component 1, pressure vessel
2nd, fluid pressure detection means 3 and controller 4 etc., so as to simulate the pressure of different immersed depths by Stress control, and
Required pressure can be realized by adjusting gas pressure, simple to operate, and immersed depth simulation context is wide, and testing equipment is to capital construction
It is required that low, and by absolute pressure closed-loop control, do not influenceed by height above sea level and external environment, at the same can reduce experiment into
This.
