Daily maintenance and maintenance skills of Nanjing Huake's programmable high and low temperature alternating heat and humidity test chamber

To ensure the proper operation of the testing equipment and extend its service life, please follow the maintenance instructions below. These guidelines are designed to help you maintain the programmable high and low temperature alternating humidity and temperature test chamber efficiently. **Water System Maintenance and Operating Instructions:** 1. If the machine has been running continuously for more than two months, it is recommended to clean the water system to prevent blockages or contamination from test substances. 2. **Description of the Water System:** - Open the bucket lid and fill it with distilled or purified water. - Turn on the main power, and the water will be pumped into the upper tank and then distributed to both the upper and lower cups. - **Function of the Water Cup:** Adjust the water level of the humidity sensor bar. - **Function of the Humidifier Cup:** Regulate the water level in the humidifier to maintain a consistent 7-minute water level. 3. **Water Level Adjustment:** - Lift the water cup cover and turn it left to raise the water level or right to lower it. 4. **Humidifier Bucket Water Level Adjustment:** - Adjust the lower lid: turn left to lower the water level, and turn right to raise it. Ensure the water level reaches 2/3 of the window. 5. **Humidity Sensor Rod Water Level Adjustment:** - Adjust the upper cup: turn left to lower the water level of the humidity sensor rod, and turn right to raise it. Set the water level to 8 points. 6. **Waterway System Cleaning Steps:** - Open the machine door and turn off the main power supply. - Rotate the drain valve to the "open" position to drain the water back to the lower tank through the return pipe. - Pull back the water hose, disconnect the pump motor’s power cable, and remove the outlet pipe. - At this point, the pump motor’s outlet may leak slightly—this is normal. Press the outlet with your finger to quickly drain any remaining water. - Once drained, clean each component thoroughly. - Reinstall the lower bucket, reconnect the pump motor’s power cable and outlet pipe. - Open the lower bucket lid and add distilled or purified water. Rotate the drain valve to the "off" position. - Finally, turn on the main power. The system will automatically pump water from the lower bucket to the water system components. 7. **Internal Cleaning of the Test Chamber:** - To prevent oxidation and rust on internal metal parts, wipe down the chamber at least once a month. - Remove the wind plate and use oil or organic solvents like banana water or pine oil to clean the internal sheet metal.
