What are the faults when the Sihuan freeze-drying pharmaceutical vacuum freeze dryer is used?

Sihuan freeze-drying pharmaceutical vacuum freeze-drying machine freeze-drying is to cool and freeze substances containing a large amount of water into a solid in advance
.

Then, the water vapor is directly sublimated from the solid under vacuum conditions, and the substance itself remains in the frozen ice shelf, so that the dried product does not lose the original solid skeleton structure, maintains the original shape of the material, and the product replicates.
Good water
.

Compared with other drying methods, chemical, physical and enzymatic changes are avoided, thus ensuring that the physical properties of products are not easily changed during storage
.

Common faults Common faults 1: Unstable power supply It is understood that if the normal working power supply voltage of Sihuan freeze-drying pharmaceutical vacuum freeze dryer is 215-225 volts, the compressor will not be able to operate effectively after it deviates from the allowable voltage range.
The ground work doesn't even work at all
.

For the unstable power supply voltage, the solution is to replace the qualified power supply when the power supply voltage is unqualified; when the power supply voltage is unstable, AVR (220V) can be used or a voltage regulator can be added to the original working power supply
.

Common fault 2: The temperature inside the mold is higher than 30°C.
The vacuum freeze dryer needs to operate in a suitable environment.
When the temperature inside the mold is higher than 30°C, the condenser may not be able to condense, thus causing the system to malfunction
.

The maintenance method at this time is that if the temperature inside the model is around 28°C, the user can open the rear door of the condenser or open the room door to optimize ventilation and cooling conditions
.

 　　Common fault 3: The temperature inside the model is lower than 0°C, and the temperature inside the model is too high, and it is not suitable for too low
.

If the temperature inside the model is lower than 9°C, the compressor oil will become viscous, which will easily affect the normal operation of the compressor
.

In addition, when the temperature is too low, all electronic components may be affected and malfunction may occur
.

 　　In response to this situation, the maintenance method suggested by the technicians is that when the ambient temperature is lower than 0°C, other heating equipment can be used to raise the ambient temperature and keep the temperature above 5°C and below 30°C
.

 　　Common fault 4: Too much dust on the freeze dryer or in the environment It is understood that if there is too much dust covering the condenser and compressor, it is easy to make the condenser unable to achieve the condensation effect, which directly affects the use effect of the compressor
.

 　　Therefore, regular dust removal is essential
.

It is recommended in the industry that if there is too much dust in the environment, users can regularly remove the dust covering the compressor and condenser on a monthly basis
.

To keep equipment from being damaged, dust on compressors, condensers and pipes can be removed with a soft brush
.

 　　Common fault five: the humidity in the environment is too high When the humidity in the environment is high, it is easy to cause electrical failure or short circuit
.

In response to this situation, the maintenance method is to use ventilation equipment or open windows for ventilation to reduce humidity
