Screw blowers play an essential role in industrial production, yet they may require extended shutdowns due to seasonal demand or production adjustments. To ensure the blower's safety and stability during downtime and to reduce maintenance needs upon restart, Anpu Electric, as an experienced blower manufacturer, recommends following these maintenance steps closely, especially in low-temperature or high-humidity environments. These steps will help protect the equipment from damage and extend its lifespan.
Preparations Before Long-Term Shutdown
1. Protect Electrical Equipment
Wrap electrical components, such as controllers and distribution boxes, in plastic or oil paper to shield them from moisture, dust, and other external factors. This reduces the risk of electronic parts becoming damp or oxidized, thus enhancing equipment stability and reliability.
2. Place Desiccant
Place a suitable amount of desiccant near the air filter to absorb moisture from the air. During prolonged shutdowns, replace the desiccant every six months to maintain a dry internal environment and prevent rusting of internal components.
3. Seal All Openings
Close all ventilation, exhaust, and other openings on the blower to prevent moisture, dust, or contaminants from entering. This measure helps avoid corrosion and reduces the risk of foreign objects damaging the fan blades and internal structures.
4. Perform a Fault Check
Conduct a thorough inspection before shutdown to ensure any issues or malfunctions are resolved. Addressing potential issues in advance saves time and costs when restarting the equipment.
Maintenance During Long-Term Shutdown
1. Regularly Inspect Equipment Condition
Every three to six months, check the equipment’s seals, electrical protection, and desiccant status to catch potential issues early.
2. Maintain Cleanliness
Keep the blower's surface clean to prevent dust buildup that could impact performance. Use a dry cloth to gently wipe the surface as needed, preventing dust from entering the interior and causing corrosion.
3. Control Ambient Temperature and Humidity
The storage environment should remain dry and well-ventilated. In high-humidity areas, use a dehumidifier or air conditioner to regulate temperature and humidity, especially during rainy seasons, to prevent moisture-related damage.
Preparations for Restart After Long-Term Shutdown
After a long shutdown, follow these steps to ensure a safe restart:
1. Remove Protective Materials
Take off any plastic or oil paper coverings from electrical components to allow for proper ventilation. Check for any signs of dampness or rust.
2. Inspect Motor Insulation Resistance
Measure the motor's insulation resistance with specialized equipment. It should be above 1 MΩ to ensure good insulation and prevent leakage or short circuits.
3. Lubricate Key Parts
Before restarting, add lubrication to critical parts such as bearings and gears to minimize wear and operational resistance, ensuring smooth blower operation.
4. Gradually Start the Equipment
Begin at low speed and gradually increase to normal operating speed to ensure stability during adaptation. Monitor the equipment for unusual noises or vibrations.
5. Follow Startup Commissioning Procedures
Strictly adhere to the manufacturer's commissioning steps during startup, including adjusting air inlets and outlets and monitoring pressure gauges, to confirm all performance indicators are within normal ranges.
