Analysis of the most common troubleshooting for cryogenic storage boxes

Although the refrigeration system and control circuit of the low-temperature storage box are relatively complicated, the most common faults are mainly faults of the circulation system and the circulatory part;MzxTextile Testing Instruments, Testing Equipment Manufacturer


The following are some common faults presented in low-temperature storage boxes and their solutions. MzxTextile Testing Instruments, Testing Equipment Manufacturer


1. After power on, the main power supply air switch will be disconnected automaticallyMzxTextile Testing Instruments, Testing Equipment Manufacturer


Remedy: Check the compression of the refrigeration system of the cryo storage box If it is damaged it will cause short circuit and current protection. MzxTextile Testing Instruments, Testing Equipment Manufacturer


The accessories can be exchanged. If there are no original accessories, you can replace the refrigerator compressor with a considerable power by calculation and weld the pipes;MzxTextile Testing Instruments, Testing Equipment Manufacturer

br/ After adding After checking the airtightness of the pipeline, suck R-12 Freon 23.00z off, add it and then turn it on tocheck if it is normal. MzxTextile Testing Instruments, Testing Equipment Manufacturer


Error Reason: This error is generally caused by unstable power supply as the stage starts first so the damage is usually in the stage;MzxTextile Testing Instruments, Testing Equipment Manufacturer


Under normal circumstances, as long as the time-delay stabilized power supply is installed, the error generally does not occur again. MzxTextile Testing Instruments, Testing Equipment Manufacturer


2. The temperature in the box stops working before the set temperature is reached.MzxTextile Testing Instruments, Testing Equipment Manufacturer


Remedy: Although the box does not reach the set temperature the box stops working Control panel The displayed temperature has reached the set temperature. MzxTextile Testing Instruments, Testing Equipment Manufacturer


This is because the thermistor used to measure temperature is damaged and needs to be replaced. If original accessories are not available, a temperature control system can be installed to rectify the error. MzxTextile Testing Instruments, Testing Equipment Manufacturer


3. The cooling effect of the refrigerator will be reduced and people verfeel an electric shock when they touch the metal part of the box.MzxTextile Testing Instruments, Testing Equipment Manufacturer


Remedy: Use a multimeter to measure the refrigerator leakage and use the Paragraph test. MzxTextile Testing Instruments, Testing Equipment Manufacturer


If the high temperature compressor is on alone, check if the low temperature storage box is live due to the compressor leaking. MzxTextile Testing Instruments, Testing Equipment Manufacturer


Statically check the compressor connection, paying attention to the motor winding connector plug. If signs of inflammation can be seen on the housing, this indicates a leak. MzxTextile Testing Instruments, Testing Equipment Manufacturer


Using the method of replacing the connector along with part of the surrounding case, install the case, power it up to run and check for leaks;
