Common Issues and Troubleshooting Methods for Tube Ice Machines

1. High Voltage Protection / Troubleshooting

Possible Causes and Solutions

• Non-condensable gas in the system: Vent air from the condenser to eliminate the gas buildup.
• Clogged water circuit in the condenser: Open the valve or clean the pipeline to restore water flow.
• Insufficient condensate and high water temperature: Increase the water flow to optimize the cooling process.
• Condenser scaling: Perform cleaning and descaling to ensure efficient heat exchange.
• Excess refrigerant: Carefully remove any excess refrigerant from the system.
• Cooling tower or evaporative cooling water shortage: Resolve water replenishment issues to maintain proper cooling performance.
• Damage to cooling tower components: Replace damaged blades, motors, or water pumps, or address power supply issues as needed.
• Leaking or broken suction valve plate: Replace the valve plate and perform leak detection and repairs.
• Poor ventilation in cooling towers or air coolers: Improve ventilation to enhance cooling efficiency.

2. Low Voltage Protection / Troubleshooting

Possible Causes and Solutions

• Low refrigerant levels: Locate the leak and refill the system with the appropriate refrigerant.
• Expansion valve issues: If the valve is too small or blocked, adjust it or replace it for proper flow.
• Faulty solenoid valve: Inspect and replace the solenoid valve if it’s malfunctioning.
• Clogged filter and closed liquid valve: Clear the blockage and fully open the valve for uninterrupted flow.
• Excessive frosting on the evaporator: Defrost the evaporator to restore normal operation.
• Excessive ice-making time: Reduce the time for ice production to avoid overloading the system.
• Issues with expansion valve or ice blockages: Conduct targeted troubleshooting to clear blockages and resolve valve issues.

3. High Oil Pressure / Troubleshooting

Possible Causes and Solutions

• Inaccurate oil pressure gauge: Inspect, calibrate, or replace the pressure gauge to ensure accurate readings.
• Incorrect adjustment of oil pressure regulating valve: Adjust the valve to the correct pressure setting.
• Blocked oil drain pipe: Clean the pipe and clear any blockages for smooth oil drainage.
• Obstructions in the refrigeration system pipes: Inspect the piping for blockages and clean or replace as necessary.
• Excess oil in the system: Drain the excess oil promptly to prevent system inefficiency.
• Gas mixed in the refrigeration system: Perform an exhaust treatment to remove any trapped gas.

4. Low Oil Pressure / Troubleshooting

Possible Causes and Solutions

• Damaged oil pressure gauge and clogged oil circuit: Calibrate or replace the gauge and clean the oil discharge pipeline.
• Low oil level: Refill the oil to the proper level to avoid damage to the system.
• Improper adjustment of the oil pressure regulating valve: Adjust the valve to the proper pressure setting.
• Excessive refrigerant dissolved in oil: Adjust the expansion valve to prevent oil contamination.
• Excessive clearance between oil pumps: Adjust or replace components as necessary to restore efficiency.
• Blocked oil suction pipe or clogged filter: Clean the suction pipe and internal oil filter or replace the oil filter if necessary.
