Reasons for the failure of medical heating and low temperature units

The medical heating low-temperature unit is mainly used in industrial processing.
It uses refrigerant as a medium to transfer the heat generated by other instruments or equipment that needs to be cooled, and dissipates the heat to the outside of the equipment through the refrigeration system, so as to ensure that the equipment is in normal operation.
work within the temperature range
.


The scaling or blockage of the condenser of the pharmaceutical heating low-temperature unit may also lead to equipment failure.
If it is not a closed system, dust and foreign matter can easily enter the cooling water system, causing the condenser to be dirty and blocked, the heat exchange area is small, the efficiency is low, and it also affects the water.
Therefore, the unit should be backwashed regularly, and chemical cleaning and descaling should be carried out if necessary
.

In addition, once the equipment is charged too much refrigerant, it may also lead to high pressure failure, the suction and discharge pressure and balance pressure are high, and the compressor operating current is also high
.

The medical heating low-temperature unit needs to pay attention to the fact that the circuit breaker cannot be easily closed after tripping, and it is not allowed to directly start the motor across the circuit breaker.
The gate can only be closed after proper handling
.

If the medical heating low-temperature unit needs to be stopped regularly (note: non-long-term shutdown), the power supply cannot be cut off at will, and the heater in the box should be kept in the heating state during the temporary shutdown
.

　　During operation, if it encounters a shutdown, pay attention to the ultra-low pressure of the suction, the high temperature of the exhaust and the small flow, and it will automatically reset after the fault is eliminated
.

If the fault is eliminated, you need to press the manual reset button on the protection switch, and then press the stop switch to restart the operation
.

When the medical heating low-temperature unit is running, the operator also needs to record its operation status and check whether there is any noise at any time.
After long-term use, regular physical examination and maintenance are required
