Recently, many customers have asked us what should be paid attention to when buying high-low temperature alternating heat and humidity test chambers. How to use them will be safer? Today, Xiaobian will focus on explaining with you.
1. After buying the high-low temperature alternating heat and humidity test chamber, it is necessary to pay attention to whether the position of the test box is reasonable and whether it is convenient for the test box to dissipate heat. It is also necessary to check the power supply of the equipment, whether it is grounded, and whether it is a dedicated line.
Second, the user should carefully read the attached product manual before use to check the various components of the high and low temperature alternating heat and humidity test chamber. The power supply of this equipment is mostly AC380V±10% 50±0.5Hz three-phase five-wire system. Be sure to avoid voltage fluctuations too much. If the voltage is high or low, it will affect the normal operation of the compressor and even burn the compressor.
Third, after the inspection is correct, the high and low temperature alternating heat and humidity test chamber should be allowed to stand for 2 to 6 hours before turning on again to avoid oil circuit failure (test box after handling). After turning on the power, carefully listen to the sound of the compressor during startup and operation, whether there is any sound of the pipeline hitting each other. If the noise is too large, check whether the product is placed smoothly, whether the pipelines are in contact, and do the corresponding Adjustment. If there is a large abnormal sound, immediately turn off the power and contact professional after-sales personnel.
Fourth, load-down operation is required when starting to use, because the moving parts of the new machine have a running-in process. Add a large amount after the operation for a period of time, which can prolong the life of the high and low temperature alternating heat and humidity test chamber.
