Installation specifications and key points for operation and maintenance of explosion-proof fans

1. Installation process ① Foundation fixation: For steel frame roofs, all-aluminum fans are preferred, and for concrete bases, anti-vibration gaskets need to be pre-embedded. ② Pipe connection: Use anti-static flexible hoses, with the elbow radius ≥1.5 times the pipe diameter to reduce wind resistance. ③ Electrical test: Before operation, the insulation resistance (> 5MΩ) should be measured with a 500V megohmmeter. 2. Common operation and maintenance issues Excessive vibration: It is mostly due to the imbalance of dust accumulation on the impeller. It is necessary to clean and perform dynamic balance correction every quarter. Motor overheating: Check the bearing lubrication and replenish the grease in time. 3. Trends in intelligent monitoring The new type of fan integrates a temperature sensor and an Internet of Things module, which can issue real-time warnings for abnormal temperature rise (automatically shut down when the temperature exceeds 60℃).
