What are the maintenance techniques for salt spray testers?
First, the amount of spray is insufficient
cause of issue:
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.
Second, when the water level is low, 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.
Third, there is a normal spray and the air compressor is not running.
The cause of the malfunction: The air compressor itself has a self-protection function.
Treatment: Use as usual without affecting the test process.
Fourth, 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 main switch of the air compressor outlet is not open;
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;
3.4.5. Notify the repair company to repair the door;
6. Remove the nozzle and clean it (please disassemble it carefully).
Five, can not run after turning on the power
Cause of failure: 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.
Sixth, when the temperature controller displays 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.

A petri dish is a laboratory vessel used for microbial or cell culture, consisting of a flat disc-shaped bottom and a lid, generally made of glass or plastic. The materials of petri dishes are basically divided into two categories, mainly plastic and glass. Glass can be used for plant materials, microbial culture and adherent culture of animal cells. The plastic ones may be polyethylene materials, which are disposable and multiple-use, suitable for laboratory inoculation, streaking, and bacterial isolation operations, and can be used for the cultivation of plant materials.
