Common faults and troubleshooting methods of salt spray testing machine

Salt spray testing machine is a commonly used instrument that assesses the ability of materials and their protective layers to resist salt spray corrosion, as well as compares the process quality of similar protective layers. It can also evaluate the ability of certain products to resist salt spray corrosion. However, as an instrument, it is inevitable that there will be malfunctions. So how can we solve this problem?

1. Unable to operate normally after turning on the power

Answer: Check if the water level in the heating water tank is too low. When the water level is too low, the equipment will cut off the power supply to ensure the safety of the equipment; Therefore, when such a malfunction occurs, please first check the water level in the heating water tank. If it still cannot operate normally after removing this malfunction, it must be a functional failure of the salt spray testing machine equipment. At this time, contact the manufacturer for repair.

2. How to deal with low water level in salt spray machine?

Answer: It depends on whether it is the low water level light in the laboratory or the low water level light in the pressure tank. When the low water level light in the laboratory is on, water is added to the pressure tank.

3. What is the problem with the salt spray testing machine not being able to open?

Answer: If the operation cannot be turned on, first check if the low water level light is on. If the low water level light is on, then you need to add water and add it well. If the water is added well but still cannot be turned on, the general problem is that the timer is broken. Just replace the timer.

4. Is it a problem that the low water level is still on after adding water and cannot be opened during operation?

Answer: This is because the water level gauge is broken and needs to be replaced.

5. What is the problem of not spray the salt spray tester?

Answer: First, check if there is air pressure on the intake pressure gauge. If there is air pressure on the intake, then check if the nozzle is blocked. If the nozzle is not blocked and there is air coming out, then the nozzle needs to be replaced.

6. There is normal spray, but the air compressor does not work normally

Answer: In general, for the safety of the equipment, the air compressor of the salt spray testing machine is usually equipped with an automatic protection system. When the salt spray testing machine is used abnormally, the air compressor will automatically stop running. Therefore, when such a fault occurs, you can continue to use it as usual.

7. Salt spray tester equipment spray untimely

Answer: When such a fault occurs, the laboratory temperature should be checked immediately to see if it has risen to the preset temperature, because if the temperature has not reached the preset temperature, the timing equipment will definitely assume that the experiment has not started yet. Therefore, such faults can be eliminated by checking the preset temperature and the actual temperature; Of course, it may also be that the set time is the same as the time of spray, so the timing time cannot be observed.

8. The nozzle is good. Open the spray switch. The barometer has no air pressure. What's the problem with the air in?

Answer: The spray solenoid valve is broken and needs to be replaced.

9. When the salt spray tester spray, what is the problem of air coming out from the water inlet of the laboratory?

Answer: The laboratory solenoid valve and the inlet solenoid valve of the pressure tank are both broken and need to be replaced.

10. How could there be air coming out of the defogging port when the switch of the salt spray testing machine is not turned on?

Answer: The defogging solenoid valve is broken and needs to be replaced.

11. How can spray occur when the salt spray tester is not connected to the automatic water inlet switch or turned on?

Answer: The spray solenoid valve is broken and needs to be replaced.

12. What is the problem with the salt spray testing machine not turning on the low water level light even when connected to the automatic water inlet?

Answer: The inlet solenoid valve is broken and needs to be replaced.

13. What is the problem with the salt spray testing machine having air coming out of the sealing groove during normal operation?

Answer: This is because the exhaust pipe is blocked and the air pressure cannot be released. Over time, the box of the salt spray testing machine will deform, which is a serious problem.

14. What is the problem with the instrument of the salt spray testing machine having an output and a solid-state relay having an output but not heating up?

Answer: The heating tube is broken and needs to be replaced.

15. The instrument of the salt spray testing machine has stopped heating, but the temperature is still heating. What is the problem?

Answer: The solid-state relay is broken and needs to be replaced.

16. What is the problem with the salt spray testing machine instrument not displaying temperature and only displaying 1?

Answer: Generally, it's because the temperature sensing wire is broken, but it doesn't necessarily mean that the instrument panel is damaged.

17. The touch screen is not responding
