How to deal with and prevent common failures of the salt spray test chamber?

Salt spray test chamber, salt spray machine, salt spray test for short, due to the salt spray test machine for a long time to do salt spray aging test, environmental discomfort and not regular cleaning and maintenance, easy to cause salt spray test machine large and small failures, in order to have households can quickly solve the fault, continue to do salt spray aging test, the following details of some common failures and treatment methods and attention to the prevention of matters.


1. The test chamber can not rise to the set temperature


Failure causes.


Salt spray test chamber temperature controller temperature, set too low;

Test chamber safety protection switch is set too low;

Heating system failure;

Electromagnetic relay failure;

Controller failure.


Handling method.


Set the temperature controller to the desired temperature;

Set the safety switch to the desired temperature;

Notify the maintenance company to repair.

2. Salt spray corrosion test chamber temperature of the saturated barrel can not rise to the set temperature


Cause of failure.


Saturated barrel temperature controller temperature is too low;

Saturated barrel safety protection switch is set too low;

Heating system failure;

Electromagnetic relay failure;

Controller failure.


Treatment.


Set the temperature controller to the desired temperature;

Set the safety switch to the desired temperature;

Notify the maintenance company to repair.


3. Salt spray test chamber spray volume is insufficient


Cause of failure.


Spray regulator is placed too low;

Preheating tank in the glass filter blockage;

Pressure setting is too low.


Treatment methods.


Turn up the spray regulator;

Clean the glass filter;

The regulator will be adjusted to 1Kg per square centimeter of pressure, the air compressor is marked - regulator, adjust to 2Kg per square centimeter of pressure.


4. Salt spray test chamber water level is insufficient when the alarm light is on


Cause of failure: indicates that the water level is too low.

Treatment: check whether the test chamber or saturated barrel water level is sufficient.


5. Salt spray test chamber with normal spray and air compressor is not running


Cause of failure: the air compressor itself has the function of self-preservation.

Treatment: use as usual, does not affect the test process.


6. Salt spray tester can not spray


Failure causes.


Air compressor is not running;

The air compressor export switch is not open;

Solenoid valve failure;

Pressure gauge failure or pressure is too low;

Solenoid contactor failure;


7. Salt spray test chamber nozzle blockage;


Treatment method.


Turn on the compressor button;

Turn on the main switch of the compressor;

Notify the maintenance company to repair;

The nozzle will be removed to clean (please be careful disassembly).


8. After opening the power supply, salt spray test chamber can not run


Cause of failure: the water level in the heating water tank is too low will cut off the operation of the power.

Treatment: The water level of the heating water tank can be increased to the normal condition.


9. When the salt spray tester temperature controller display alarm and debugging failure


The cause of the failure: temperature controller failure, temperature-sensing rod failure.

Treatment: notify the maintenance company to repair.
