Maintenance Suggestions
Based on decades of on-site maintenance experience, our engineers provide practical, easy-to-follow suggestions to extend the service life of spare parts and avoid common faults: For push buttons (0000-6853-78/79), clean the surface with a dry cloth every 150 working hours to remove dust and mud, and check for loose connections—avoid using water or chemical cleaners, as they may damage the waterproof seal. For PCB assemblies (0509 series), inspect the circuit board for corrosion or loose components every 300 working hours; if corrosion is found, clean it with a neutral cleaning agent and dry thoroughly. For mud flow sensors (40224227-005), check the paddles for wear every 200 working hours; if worn, replace the paddles immediately, and clean the sensor probe with clean water to avoid mud buildup affecting measurement accuracy. For explosion-proof components (BQD5 series), check the explosion-proof seal every 400 working hours; if the seal is damaged, replace it to maintain explosion-proof performance. For gas sensors (370-010000-700, 370-201600-700), calibrate the sensor every 6 months to ensure detection accuracy—use standard gas for calibration, and avoid calibrating in areas with high gas concentrations. For transformers and resistors, check for overheating every 250 working hours; if the surface temperature exceeds 80°C, shut down the system and inspect for faults. A key reminder: When replacing explosion-proof components, ensure the replacement part has the same explosion-proof rating (Ex d IIB T6) to avoid safety hazards.
