The data of real time temperature T are passed in power control cabinet 17, after the analysis comparison of power control cabinet 17, it is found that the temperature at the moment is less than
The lower limit of preset value sends out overheating warning, and issues the control instruction for promoting temperature to the first warm and humid sensor 2 simultaneously immediately,
The control instruction sends the controller of constant temperature and humidity machine 1 to via the first warm and humid sensor 2, which stands after receiving instruction
I.e. control changes 1 working condition of constant temperature and humidity machine, promotes wind pushing temperature, and the wind for promoting temperature is sent via dry air hose 3 to quartz
At nozzle 12, to improve the temperature of the high-pressure aerial fog of the ejection of quartz nozzle 12, the aerosol by spray chamber 16 and working chamber 20 it
Between circular through hole be blown into working chamber 20, cause 20 internal temperature of working chamber to be gradually promoted to preset range, when second warm and humid
When the temperature value that sensor 18 monitors is in values, power control cabinet stops sending heating and instructing switching to keep the temperature
Instruction be issued to constant temperature and humidity machine 1, constant temperature and humidity machine 1 keeps sending out the hot wind of Current Temperatures.If temperature exceeds preset value,
Cooling air-supply then is carried out according to above workflow, is no longer repeated herein.If humidity transfinites, then also according to above
Workflow send out the instruction for increasing humidity or reducing humidity, the humidification or wet down of air-supply are executed by constant temperature and humidity machine 1
Work.
By above description it is found that the beneficial effects of the utility model are：
It, can be according to experiment demand using constant temperature and humidity salt spray test device, it can be achieved that the salt air corrosion environment of constant temperature and humidity
Ambient temperature and humidity and salt fog amount are controlled to adjust, and wider range of controllable adjustable.So that conclusion (of pressure testing) can
It is greatly increased by property.
Above disclosures are merely preferred embodiments of the utility model, with this utility model cannot be limited certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
