How to deal with the failure of the salt spray test chamber
Because the salt spray test chamber has long been tested for salt spray aging, the environment is prone to cause the salt spray test machine to have large and small faults. In order to solve the fault quickly, the salt spray aging test will continue smoothly. Some common faults are described in detail below. And processing methods.

First, the laboratory can not rise to the set temperature. Causes of failure: 1. The temperature of the test room temperature controller is set too low; 2. The test room safety protection switch setting is too low; 3. The heating system is faulty; 4. Electromagnetic Relay failure; 5. Controller failure.
Treatment method: 1. Set the temperature controller to the required temperature; 2. Set the safety protection switch to the required temperature; 3.4.5. Inform the maintenance company to repair the door.
Second, the saturated barrel temperature can not rise to the set temperature. Causes: 1. The saturated barrel temperature controller temperature is too low; 2. The saturated barrel safety protection switch setting is too low; 3. The heating system is faulty; 4. The electromagnetic relay is faulty; 5. Controller failure.
Treatment method: 1. Set the temperature controller to the required temperature; 2. Set the safety protection switch to the required temperature; 3.4.5. Inform the maintenance company to repair the door.
Third, the amount of spray is insufficient. Causes: 1. The spray regulator is placed too low; 2. The glass filter in the preheating tank is blocked; 3. The pressure setting is too low.
Treatment method: 1. Increase the spray regulator; 2. Clean the glass filter; 3. Adjust the pressure regulator to a pressure of 1Kg per square centimeter, and press the pressure regulator on the air compressor to adjust to 2Kg. Pressure per square centimeter.
4. When the water level is low, the alarm light is on. The cause of the failure is: the water level is too low.
Treatment: Check if the test chamber or saturated tank is adequately water level.
5. There is a normal spray and the air compressor is not running. Cause: The air compressor itself has the function of self-protection.
Treatment: Use as usual without affecting the test process.
Sixth, unable to spray the cause of the failure: 1. The air compressor is not running; 2. The main switch of the air compressor outlet is not open; 3. The solenoid valve is faulty; 4. The pressure gauge is faulty or the pressure is too low; 5. The electromagnetic contactor is faulty; 6. Nozzle blockage;
Treatment method: 1. Open the air compressor button; 2. Open the air compressor main switch; 3.4.5. Inform the maintenance company to repair the door; 6. Remove the nozzle and clean it (please disassemble it carefully).
Seven, can not run after turning on the power failure Cause: When the water level in the heating tank is too low, the power supply will be cut off.
Treatment method: Add the water level of the heating tank to the normal condition.
Eight, when the temperature controller shows HHH, LLL
The cause of the malfunction: the temperature controller is faulty and the temperature sensing rod is faulty.
Treatment method: notify the maintenance company to repair the door.
