How to maintain high and low temperature test chamber
Nov 25, 2017

As we all know, the high and low temperature test box needs regular maintenance in the use process, so as to better improve the performance of the machine. And the high and low temperature test box maintenance is not in place, may cause high and low temperature test box failure rate rise, how to maintain high and low temperature test box?

First, put the location

Attention should be paid to whether the location of the high and low temperature test chamber is reasonable, and whether it is convenient for the high and low temperature test box to heat the heat. Are there any flammable and explosive materials around, whether there is enough space for use and maintenance around the high and low temperature test chamber?.


Two. Read the instructions carefully

Before use, users should read the attached product instructions carefully and check the components of the high and low temperature test chamber. The power supply used in the high and low temperature test chamberis usually AC380V 50 + 0.5Hz three-phase five wire system. When normal operation, the voltage fluctuation is allowed to be between 370~390V. If the fluctuation is large or high and low, it will affect the normal operation of the compressor, and even destroy the compressor.


Three, pay attention to electricity safety

High and low temperature test box should be separately connected. Pay attention to protect the insulation layer of the power line, not to weigh the wire, not arbitrarily change or lengthen the power line.


Four, after the boot

After inspection, the high and low temperature test chamber should be installed for 2 to 6 hours before starting, so as to avoid the oil circuit fault (the high and low temperature test box after handling). After the power is switched on, listen to the voice in the startup and operation of the compressor is normal, whether there is a pipeline strike against each other's voice, if the noise is too large, check whether the product is placed smoothly, each pipe is contacted, and make corresponding adjustment. If there is a larger abnormal sound, the power should be cut off immediately and contacted with the professional repair personnel.


Five. New machine running in

When you start using it, you need to load it down, because the moving parts of the new machine have a running in process. After a period of operation, a large amount is added, which can prolong the life of the high and low temperature test chamber.


Six, reduce load operation

When using the high and low temperature test chamber, the sample can not be placed too much, and the proper space should be left to keep the air circulation in the box, so as to avoid the full load of the high and low temperature test chamber. Be careful not to place liquid or glassware in high and low temperature test chamber to damage by frost crack. With volatile, flammable chemical substances, easy to corrosion, acid and alkali items should not be placed, so as not to damage the high and low temperature test box.
