Salt spray corrosion test box troubleshooting tips Because the salt spray tester is doing salt fog aging test for a long time, it is easy to cause large and small faults in the salt spray tester because of the harsh environment. In order to solve the fault quickly, the salt spray aging test can be continued successfully. The following describes some common faults in detail. Approach. Bar Ring Cutting Turning Production Line Series Zhejiang Toman Intelligent Technology Co., Ltd , https://www.tomanmachines.com
The test chamber cannot be raised to the set temperature.
1. Laboratory temperature controller temperature, set too low;
2. The laboratory safety switch is set too low;
3. Failure of the heating system;
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;
3.4.5. Instruct the repair company to come to the door for repairs.
Saturated barrel temperature cannot rise to the set temperature Fault Cause:
1. The spray regulator is placed too low;
2. Blockage of the glass filter in the preheating tank;
3. The pressure is set too low.
Approach:
1. Increase the spray regulator;
2. Clean the glass filter;
3. Adjust the pressure regulator to a pressure of 1Kg per square centimeter. The air compressor is marked with a pressure regulator and adjusted to a pressure of 2Kg per square centimeter.
Underwater fault cause:
1. Saturated barrel temperature controller temperature is too low;
2. The saturation bucket safety switch is set too low;
3. Failure of the heating system;
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;
3.4.5. Instruct the repair company to come to the door for repairs.
Insufficient fog
Cause of failure: Indicates that the water level is too low.
Treatment method: Check whether the water level in the laboratory or saturated tank is sufficient.
Air compressor
Cause of failure: The compressor itself has its own function.
Treatment method: use as usual, does not affect the test process.
Clogged nozzle
Approach:
1. Open the air compressor button;
2. Open the air compressor main switch;
3.4.5. Inform the repair company of the door repair;
6. Remove the nozzle and clean it (please be careful about disassembly).
Can't spray
cause of issue:
1. The air compressor is not operating;
2. The main switch of the air compressor outlet has not been opened;
3. Electromagnetic valve failure;
4. Pressure gauge failure or pressure is too low;
5. Electromagnetic contactor failure;
Unable to operate
Cause of failure: temperature controller failure, temperature sensor stick failure.
Treatment method: Inform the repair company about the door repair.
Cause of failure: When the water level in the heating tank is too low, the power of the operation will be cut off.
Treatment method: Add the water level in the heating tank to normal conditions.

Installation Considerations II. Requirements for Power Supply System of Salt Spray Test Chamber
1, power requirements: single-phase AC 220V 50Hz
2, current requirements: Max 15 A
3, protection requirements: need to install an independent leakage protection switch, salt spray test chamber fill water system installation
1, water quality requirements: industrial water or tap water filter (filtered water pH between 6.5 ~ 7.2) or pure water (mineral water can not use minerals)
2, pressure requirements: water pressure in 1 ~ 3 kg, to ensure normal water.
3, the interface requirements: equipment at the water inlet should be connected with a hose, using a seal to prevent leakage.
Fourth, salt spray chamber exhaust system requirements
1. Material Requirements: PVC Polyethylene Material (Corrosion Resistant) must be used
2. Interface requirements: The exhaust port of the equipment needs to be connected with a hard pipe and sealed with a sealant to prevent air leakage.
3, drilling requirements: the device is a natural exhaust, the height of the wall openings need to be slightly higher than the exhaust hole, to ensure the gas flow back to the laboratory after condensation, the salt spray test chamber intake system installation
1, pressure requirements: air compressor or air supply pipe pressure ≥ 3 kg, and dry and clean
2. Interface requirements: The device uses a quick connector to facilitate removal and maintenance
3. Time requirements: The equipment must be supplied with gas for a long time without interruption during normal operation. 5. Salt spray test chamber drainage system installation
1. Drilling requirements: The equipment is natural drainage without pressure, and the opening height of the wall must be lower than the drainage outlet to ensure that the drainage is working properly.
2. Interface requirements: The equipment outlet should be connected with a hose or a hard pipe. Use a sealing ring to prevent leakage.
