Simple household high and low temperature box maintenance to do this is safe Why is there a heat around the door of the high and low temperature test chamber; (except the dew tube device) When the high and low temperature test chamber is turned on, you will find that it is very hot around the door seal of the box. This is the intention of Shanghai Jianhao Instrument Equipment Co., Ltd., because of the low temperature test of the high and low temperature test chamber. When the interior is very cold, when the outside temperature is high, there will be "sweat" condensation on the doorway. Therefore, the designers of the simple households will take the gas line at the outlet of the compressor first around the door for a week, and use the heat of the pipeline to drive away. Drops of water formed by condensation (this section of the pipeline is referred to as the door seal tube, also called the door seal dew tube). Inspection of common faults in high and low temperature test chambers 1. Poor cooling: Whether the test sample is placed too much or a hot sample is placed. Whether to open the door frequently or the door seal is not strict. Whether there is a heat source near direct sunlight or high and low temperature test. Is it poorly ventilated? Check that the ambient temperature is too low and the temperature compensation switch is not turned on. 2, high and low temperature test box can not start sound: under normal ambient temperature conditions (15 ° C -30 ° C), when the high and low temperature test chamber starts, if the compressor emits a "beep" sound, the compressor stops working for about half a minute, this In this case, the compressor cannot be started because the power supply voltage is too low; if the compressor makes a “beneath†sound, it will hear a “beep†sound, because the power supply voltage is too high or the compressor continues to work for too long. The high and low temperature test chambers can work normally when the power supply voltage returns to normal or the compressor casing temperature drops.
