First, the amount of ice produced is reduced
1. Capillary or expansion valve plugging.
2. There is a slight ice block in the system where the water is too high.
3. The condensing system of the ice machine is blocked.
4. Insufficient refrigerant or leakage.
5. The evaporator is too dirty.
Second, the machine is running but not ice
1. The water in the water tray is not enough or no water.
2. The gear unit is faulty or the geared motor.
3, the system is blocked by ice. Dirty blockage, etc.
4, ice machine leaking snow, insufficient pressure
5, the ice is not thick enough
Third, the compressor interrupted work:
1. The voltage is too low. Check the power supply.
2, the contact point burning contact is not good.
3. System pressure protection.
4. The compressor starter is faulty.
5, the condenser is too dirty, high voltage protection.
Fourth, the ice machine leaks
1. The water supply to the water inlet valve is too large.
2. The damaged water pipe is damaged.
3. The hose clamp is faulty.
4. The water level float valve is faulty.
Five, wet ice borneol is not hard
1. The ambient temperature is too high, especially in summer.
2, repaired machine refrigerant added.
3. The water supply of the ice machine water distribution tray is too large.
4. The power of the press is insufficient.
Sixth, boot report system failure
1. Phase sequence problem.
2. The power supply system is faulty.
3, the control board is faulty
Seven, the noise is too big
1. The ice machine fan is faulty.
2. The speed reducer is faulty.
3. The compressor is noisy.
Eight, water shortage alarm
1. The water supply joint filter is blocked.
2. The water supply pipe is blocked.
3. The inlet valve is blocked.
4. The drain valve leaks.
5. The pump is faulty.
First, the compressor failure:
1. First check if the compressor can start normally and measure whether the compressor voltage is normal.
2. If the voltage is normal, check the static resistance. Whether the static resistance voltage is balanced and stable. If the resistance is not balanced, look at the motor group for a short circuit. Is there a problem with the winding? If the resistance is stable, look at the compressor temperature is also stable. If the temperature is too high, it will be cooled for a while. Try again in 2-3 hours.
3. If all is normal, see if the bearing is healthy.
Second, the compressor is noisy.
1. Check if the screw of the compressor is firm and there is no slippage or collapse.
2. Test if the current is stable. Is it too high?
3. If the compressor fluence is too large, look at the cooling effect of the compressor and whether it is overheated.
4. Check if the compressor has a reversal. Whether the compressor has been aging damaged.
Third, the suction and exhaust pressure is insufficient.
1. If the suction and exhaust pressure is found to be low or high, it is generally a problem with the chiller system.
2. When the exhaust pressure is low, the defrost system is normal. If there is noise in the defrost, it is normal.
Fourth, the current
1. The current check can be limited not only to the compressor, but also whether the voltage of the motor itself is stable.
2. Detect check valve and oil, whether the original is normal.
