As a core component of the high-low temperature test box, the compressor directly affects the performance of the equipment. Combining years of experience in production and sales, Comb provides the following suggestions for the maintenance of the compressor. We hope to give you a reference.
1. Do not start the compressor frequently during use. The interval between the start of the compressor must be at least 15 minutes. 2. The working environment should be well ventilated and free of dust. The surface of the compressor must be kept clean. If the test is not used for a long time, The box should be placed in a space that is as dust-free as possible. 3. The voltage in the workplace must be stable. If the voltage is unstable, the current will be too large or too small. Running in this environment for a long time will cause the compressor to Extremely damaged, it is recommended to use a voltage regulator to connect the high and low temperature test chamber. IV. Environmental requirements for equipment use:
1. Smooth ground, well ventilated, free from flammable, explosive, corrosive gas and dust
2. There is no strong electromagnetic radiation source nearby
3, there is a proper maintenance space around the equipment
4, temperature: 5 °C ~ 30 °C (average temperature within 24 hours ≤ 30 °C)
5, Relative Humidity: ≤85%RH (Air conditioning must be turned on in summer)
6, pressure: 86 ~ 106kpa
