Specification for Industrial Pharmeceutical Freeze Dryer

Common problems and Solutions

1.The air return of the compressor thermal protection system (motor temperature over 85 ℃) is insufficient and the motor is not cooled sufficiently.

Solutions:

(1) adjust the intercooler expansion valve, increase the circulation of the system, so that the motor is fully cooled.

(2) Check whether the liquid supply pipeline is blocked (liquid supply stop valve, drying filter, solenoid valve, filter screen in front of expansion valve, etc.), and solve the problem if any.

(3) Check whether the air return pipeline and the suction filter of the compressor are blocked, and repair the blockage.

(4) Check whether there is a lack of refrigerant, if not, replenish it. A kind of

When the 220 V control power supply of thermal protection is turned off and restarted, the alarm can be eliminated.

2.Water pressure alarm

(1) The cooling water pressure is lower than the pressure set by the water pressure relay. It is necessary to ensure that the cooling water pressure is higher than the pressure set by the water pressure relay, and the pressure set by the water pressure relay can be properly adjusted under the condition that the cooling effect is guaranteed and the compressor high pressure does not alarm.

(2) Water pressure relay failed. The water pressure relay needs to be replaced.

3.Compressor fails to start

(1) Alarm, one of the alarm, water pressure differential protection. It is necessary to find out the cause of the alarm and eliminate the alarm.

(2) The instantaneous starting current is too large, which leads to thermal overload protection or air switch protection. It is necessary to find out the cause of high current and reset the thermal overload to start.

(3) The crankshaft and piston cylinder of the compressor are seized. The compressor needs to be repaired.
