The products produced and sold by Lito Instruments are mainly materials, toys, footwear, leather, plastics, packaging and transportation, electronics, office furniture, luggage, environmental, baby carriage, paper, printing. , tapes and other test equipment. The product is suitable for shoes, leather, paper, printing, packaging and transportation, rubber, plastic, dyeing and finishing, metal, electronics, wire and cable, furniture, etc. 1. The salt spray test machine laboratory can not rise to the set The temperature of the salt spray test machine failure causes:
1. The temperature of the test room temperature controller is set too low;
2. The laboratory safety protection switch setting is too low;
3. Heating system failure;
4. Electromagnetic relay failure;
5. Controller failure;
Salt spray test chamber treatment method:
1. Set the temperature controller to the desired temperature;
2. Set the safety switch to the desired temperature;
3. Inform the maintenance company to repair the door;

Second, the salt spray test machine saturation barrel temperature can not rise to the set temperature failure reasons:
1. The temperature of the saturated barrel temperature controller is too low;
2. The saturated bucket safety protection switch setting is too low;
3. Heating system failure;
4. Electromagnetic relay failure;
5. Controller failure.
Approach:
1. Set the temperature controller to the desired temperature;
2. Set the safety switch to the desired temperature;
3. Inform the maintenance company to repair the door.
Third, the salt spray test machine has insufficient spray volume.
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.
Approach:
1. Raise the spray regulator;
2. Clean the glass filter;
3. Adjust the pressure regulating valve to a pressure of 1Kg per square centimeter. The air compressor is marked with a pressure regulating valve and adjusted to a pressure of 2Kg per square centimeter.
Fourth, the salt spray test machine water level is insufficient when the warning light is on. Cause: The water level is too low.
Treatment: Check if the test chamber or saturated tank is adequately water level.
5. The salt spray test chamber has normal spray and the air compressor does not run. Cause: The air compressor itself has the function of self-protection.
Treatment: Use as usual without affecting the test process.
Sixth, the salt spray test machine can not spray PS: nozzle air pipe and suction pipe device method (straight pipe is suction pipe; L type is air pipe)
cause of issue:
1. The air compressor is not running;
2. The air compressor outlet main switch is not turned on;
3. Solenoid valve failure;
4. The pressure gauge is faulty or the pressure is too low;
5. Electromagnetic contactor failure;
6. The nozzle is blocked.
Approach:
1. Turn on the air compressor button;
2. Turn on the air compressor main switch;
3. Inform the maintenance company to repair the door;
4. Remove the nozzle and clean it.
7. The salt spray test machine can't run after turning on the power. Cause: When the water level in the warm water 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, salt spray test machine when the temperature controller shows HHH, LLL
Fault reason: The temperature controller is faulty and the temperature sensing rod is faulty.
Treatment method: notify the maintenance company to repair the door.
