Common faults and maintenance methods of vacuum freeze dryer

Common faults and maintenance methods of vacuum freeze dryer one: the supply voltage is unstable and unqualified The working power supply voltage of the freeze dryer is 215-225 v deviation from the allowable voltage range will cause the compressor to fail to work effectively or not to operate at all Maintenance method: 1 When the power supply voltage is unqualified, please replace the qualified power supply 2 When the power supply voltage is not stable, AVR (220V) can be used or voltage stabilizer can be added to the original working power supply Common fault 2: when the indoor temperature is higher than 30 ℃ If the indoor temperature is higher than 30 ℃, the condenser will not be able to condense, which will lead to system failure Maintenance method: if the indoor temperature is about 28 ℃, please open the back door of the condenser or the room door to optimize the ventilation and cooling conditions Common fault 3: when the indoor temperature is lower than 0 ℃, the compressor oil will become viscous This will affect the operation of the compressor All electronic components may be adversely affected and misoperation may occur Maintenance method: if the ambient temperature is lower than 0 ℃, other heating equipment can be used to raise the ambient temperature and keep the temperature above 5 ℃ and below 30 ℃ Common fault 4: if there is too much dust on the freeze dryer or the environment Too much dust will cover the condenser and compressor, resulting in the condenser unable to achieve the condensation effect, which directly affects the use effect of the compressor Maintenance method: if there is too much dust in the environment, please remove the dust covering the compressor and condenser on a monthly basis The dust on the compressor, condenser and pipeline can be removed with a soft bristle brush Common fault 5: excessive humidity in the environment, which may cause electrical fault or short circuit Maintenance method: use ventilation equipment or open windows for ventilation, so as to reduce humidity
