Do you know a few maintenance tips for fast temperature change test chambers?

The rapid temperature change test chamber equipment is mainly for electrical, electronic products, as well as its original devices, and other materials in the high temperature, low temperature rapid change environment storage, transportation, use of the adaptability test
.
In the process of use, we must maintain and maintain it well so that it has a long service life and good
performance.
The following is a summary of 14 quick temperature test chamber maintenance tips, I hope to be able to help
users of this series of equipment.
1.
Carefully check the action sound of cylinders and moving parts at all levels according to "listening" to distinguish whether its working conditions are normal, and stop and check immediately if abnormal sounds are found; 2.
Pay attention to whether the indicator values of the pressure gauge and lubricating oil pressure gauge on the pressure gauge, gas storage tank and cooler at all levels are within the specified range; 3.
Pay attention to the temperature rise of the motor, bearing temperature and whether the voltmeter and ammeter indicate whether the situation is normal, the current shall not exceed the rated current of the motor, if it exceeds the time, it is necessary to find the reason or stop inspection; 4.
Frequently check whether there are debris or even conductive objects in the motor, whether the coil is damaged, whether the stator and rotor have friction, otherwise the motor will burn out after starting; 5.
If the water-cooled compressor cannot be connected to the water immediately after the water is cut off, the cylinder crack should be avoided due to uneven heating and cooling.
After the winter shutdown, the cooling water should be released to avoid freezing and cracking in the cylinder and other places; 6.
Check whether the cooling water temperature and flow rate are normal; 7.
The rapid temperature change test chamber checks the lubricating oil supply and the lubrication system oil supply of the movement mechanism (some compressors are equipped with plexiglass baffles on the side of the crosshead guide rail of the fuselage, which can directly see the crosshead movement and the supply of lubricating oil); The cylinder and packing can be used for oil discharge inspection by one-way cutting, and the oil injection into the cylinder by the oil injector can be checked; 8.
Observe whether the oil surface of the fuselage oil pool and the lubricating oil in the oil injector are lower than the scale line and should be added in time if it is low; 9.
Check whether the temperature is normal at the suction and exhaust cutting cover at the cross guide rail of the crankcase of the fuselage with the touch; 10.
Check whether the compressor vibrates, whether the anchor screws are loose and falling off; 11.
Check whether the pressure regulator or load regulator, safety logging, etc.
is sensitive; 12.
Pay attention to the hygiene of the compressor and its equipment and environment; 13.
Air storage tanks, coolers, and oil-water separators should often release oil and water; 14.
The lubricating machine used in the rapid temperature change test chamber should be precipitated and filtered.
Winter and summer compressor oil should be used differently.
