I maintain my equipment - constant temperature and humidity test chamber maintenance tips
In the traditional setup, the management of constant temperature and humidity test chambers was often divided among operators, inspectors, and maintenance staff. However, this approach is being re-evaluated in favor of a more integrated system. By enhancing the training of operators in equipment knowledge, they can now perform daily inspections, routine maintenance, and even basic troubleshooting on similar devices. This shift not only improves operational efficiency but also ensures that the equipment remains in optimal condition.
Under the "Inspection and Integration" model, what skills should an operator possess? First, it's crucial to understand the ideal environmental conditions for the test chamber. The manufacturer recommends placing the device in a controlled environment with temperatures between 5°C and 30°C, and relative humidity below 85% RH. If the lab cannot meet these standards, installing air conditioning becomes essential to protect the compressor and maintain experimental accuracy.
Second, regular cleaning of the waterway and humidifier is necessary. If the water supply is restricted or the humidifier becomes scaled due to mineral buildup, it may dry out and get damaged. Therefore, scheduled cleaning is vital to ensure proper operation and prevent costly repairs.
Third, the circulating fan blades and condenser fans must be kept clean. Due to the nature of the test chamber’s working environment, dust and small particles can accumulate on these components. Regular cleaning helps maintain airflow and heat transfer efficiency, which is critical for consistent performance.
If the constant temperature and humidity test chamber is not in use for an extended period, the inner walls should be cleaned and dried thoroughly. It's also recommended to power the unit at least once a week for no less than 30 minutes to keep internal components active and prevent deterioration.
Additionally, high and low-temperature test chambers should be regularly cleaned to ensure good ventilation and heat exchange. For units cooled by water, maintaining proper inlet pressure, temperature, and flow rate is essential. The condenser should also be cleaned and descaled periodically to maintain its cooling efficiency.
When relocating the equipment, it's best to do so under the guidance of technical personnel from Yashilin to avoid damage or refrigerant leaks. Proper handling during transportation is key to preserving the integrity of the system.
Ultimately, whether it's a small device or a high-precision instrument, regular maintenance is crucial to extending its lifespan and ensuring reliable performance. With the right care and attention, these machines can serve for many years without compromising their functionality.
