When using the salt spray test chamber for product testing, it usually lasts for a month or even a few months, and the harsh environment is likely to cause large and small faults in the salt spray test machine. In order to enable the user to quickly deal with the salt spray test chamber failure, continue to do the salt spray aging test smoothly, the test has introduced some common faults and treatment methods.

First, the salt spray test box spray failure causes and treatment:

Insufficient amount of spray:

1. Spray regulator is placed too low, raise the spray regulator

2. The glass filter in the preheating tank is blocked and the glass filter is cleaned.

3. Check if the nozzle is partially blocked. If there is any blockage, please discharge debris.

4, the pressure setting is too low, adjust the pressure regulating valve

Unable to spray:

1. The air compressor is not running. Open the air compressor button and check if the air compressor link of the air compressor is correct.

2. Check if the pressure of the pressure regulating valve is open, please adjust to the normal pressure value.

3. Check if the nozzle is blocked. The nozzle is a consumable item. Generally, it is normal damage after using for more than 1500 hours. The nozzle should be replaced.

4. Check if the spray switch is damaged. If it is damaged, please replace the switch.

5. Check if the spray solenoid valve is broken. If there is no air outlet, remove the solenoid valve and clean the solenoid valve. If the coil is burned, replace the matching solenoid valve coil, otherwise replace the entire solenoid valve.

6, check whether there is reagent salt, no salt water, add appropriate amount of reagent saline

Second, salt spray test chamber heating failure causes and treatment:

The salt spray test chamber cannot be heated:

1. Heating solid state relay has no output, replace solid state relay

2, the meter has no output, replace the meter

3, the heating tube is damaged, check the heating tube resistance, if not normal, please replace

4, lack of water leads to heating shielding, check whether the water level is normal, the float ball has no malfunction

5, over temperature protection malfunction, adjust the protection temperature value, if still can not solve, please replace the over temperature protection

Salt spray test chamber heating temperature is not normal:

1. The temperature of the test room temperature controller is set too low, and the temperature controller is set to the required temperature.

2. The test room safety protection switch setting is too low, and the safety protection switch is set to the required temperature.

3. The temperature of the saturated barrel temperature controller is too low, and the temperature controller is set to the required temperature.

4. The saturated barrel safety protection switch setting is too low, and the safety protection switch is set to the required temperature.

Third, the salt spray test box instrument has no display:

1. There is no power supply in the salt spray test chamber. There is no power supply. Please check with a professional electrician.

2. Is the power switch damaged? If it is damaged, please replace the power switch.

3. Is the power circuit breaker damaged? If it is damaged, please replace the circuit breaker.

4, the instrument power supply terminal has no power supply, there is power supply indicating that the instrument is damaged, need to replace the instrument

5. Check if the salt spray box instrument power supply terminal has black marks. If there is blackening, the instrument may burn out.
