The salt spray corrosion test chamber is a relatively mature technology in environmental test equipment. The equipment has stable performance and a low failure rate. However, any equipment will not rule out the situation of failure. After the salt spray corrosion test box is used for a long time, the most common failure is not to spray.
1. Check whether the gas source is normal.
2. Check the pressure gauge, the inlet pressure is 0.2 ～ 0.4mpa / spray pressure 0.07 ～ 0.17mpa, and see if the pressure gauge is adjusted to the specified range.
3. Check whether the spray switch reaches the status of I. If not, please turn on the spray switch.
4. Check whether the salt water pipe and air pipe of the nozzle are connected reversely, if it is reversed, it can be adjusted back.
5. Check whether the spire installation is too low. If it is determined that the spire installation is too low, adjust it to a suitable position. 6. Check if there is no brine in the brine tank.
7. Check whether the nozzle is clogged or broken. If it is clogged, please clean the nozzle and install it again. If it breaks, please replace the nozzle to see if the connecting hose is broken.
8. Check whether the salt water suction pipe leaks salt water. If it leaks, please replace the salt water pipe.
9. Check whether the intake pipe is blocked or falling off.
10. Check whether the solenoid valve is damaged. Detection method: use a multimeter to measure whether the solenoid valve coil has a resistance value and whether the resistance value is around 970 ohm.
If there is no spraying in the salt spray corrosion test chamber, the above is all the solutions for the equipment not spraying. The user can eliminate the fault according to the above methods.
