The reason why the constant temperature and humidity composite salt spray box does not spray

The constant temperature and humidity test chamber is a very technical machine and equipment in the environmental test equipment, the corrosion characteristics of salt spray are stable, and the rework rate is very low
.

What is said here is that the repair rate is very low, does not mean that it is not easy to appear abnormal, after the application of the constant temperature and humidity test chamber for a long time, the common common fault is that there is no spray, and the people below say that the test chamber does not spray some ways: 1, check whether the source is all normal
.

2, check the barometer, the working pressure of the air inlet is 0.
2 ~ 0.
4mpa / spray working pressure 0.
07 ~ 0.
17mpa, pay attention to whether the barometer is adjusted to a specific category, if it is not within a specific range, the working pressure must be adjusted to a specific category
.

3.
Check whether the spray power switch is in, if it is not entered, please open the spray power switch
.

4, check whether the sprinkler salt water pipe and respiratory tract are wrong, if it is wrong, it will be transferred back
.

5, check whether the minaret installation is too low, if it is clear that the minaret installation is too low, it must be adjusted to the appropriate part 6, check whether the salt storage tank has no salt water, if so, add the salt water on the line
.

7, check whether the nozzle is blocked or cracked, if blocked, please clean the nozzle clean and then installed, if there is a crack, you must disassemble the nozzle, you must also check whether the connection plastic hose is cracked
.

8.
Check whether the suction brine pipe has leaked brine, if the brine is leaked, please remove and replace the brine pipe
.

9.
Check whether the intake manifold is blocked or falls.


10, check whether the relay is damaged, the inspection method: use the digital multimeter to accurately measure whether the solenoid valve coil is resistive, the resistance is not above and below the 970 ohm, if it is damaged and replaced, it will be on the line
