With the increasing use of screw chillers, regular maintenance and preventive care have become essential. These chillers often operate in harsh conditions, which can place a heavy burden on the system. To ensure their efficiency and longevity, routine inspections and maintenance are necessary.
1. Safety Precautions
- Do not open the electrical control panel while the chiller is running to avoid the risk of electric shock.
- If abnormal noise occurs, immediately shut down the power supply.
- Keep flammable gases and materials away from the chiller, especially during high-temperature summer months.
- Do not place hands inside the chiller while it is operating.
- Always follow the proper operation and usage guidelines when using the chiller.
2. Maintenance Precautions
- Before checking the control panel, turn off the power and wait at least 10 minutes.
- Only authorized personnel should operate the electrical cabinet switches to prevent electric shock.
- Do not touch the equipment with wet hands to avoid injury or electric shock.
- If the chiller will not be used for an extended period, turn off the power for safety.
- Always use the appropriate tools when performing maintenance.
- Do not perform any maintenance or repairs while the system is still in operation.
3. Precautions Before Restarting the Chiller After Maintenance
- Check the power indicator to confirm the chiller is receiving power.
- Inspect the high and low-pressure gauges to ensure pressure levels are normal.
- Ensure there are no obstacles around the chiller.
- Check the pipelines for any blockages.
Proper maintenance and adherence to these precautions will help ensure the chiller operates efficiently and safely, reducing downtime and preventing unexpected failures.
