First, take a bath for the salt spray test machine and then go to work.
For a salt spray test machine that has not been used for an extended period, it's now back in operation. According to experts, before reusing such equipment after long-term storage, it is essential to perform necessary maintenance and repairs to ensure its proper functioning. Prolonged inactivity can lead to aging of the test chamber’s internal components and accumulation of dust on electrical parts, which may result in reduced sensitivity or malfunction. To avoid these issues, here are some important maintenance steps:
1. Thoroughly clean the working chamber and water seal tank with clean water. Also, make sure to clean the nozzle to prevent salt crystallization and blockage.
2. Before restarting the machine, inspect the electrical system to ensure all connections are secure and functioning properly.
3. Check the pressure regulating valve to confirm it is within the specified range.
4. Inspect the saturator for any presence of water and drain it through the drain valve if necessary.
5. Remove any oily water from the oil-water separator of the salt spray test machine.
6. If the nozzle is clogged, remove it and clean it using alcohol, a 1:1 mixture of hydrochloric acid, or ultra-fine steel wire. However, be careful not to damage the inner surface of the nozzle, as this could affect the spray quality and accuracy of the test.
It's also recommended to check the overall condition of the machine, including the corrosion resistance of the internal components, and ensure that all safety mechanisms are in place. Regular maintenance not only extends the lifespan of the equipment but also ensures accurate and reliable test results. Always follow the manufacturer’s guidelines and consult a professional if you're unsure about any step.
