Routine maintenance includes checking equipment operating status, monitoring operating parameters such as pressure and temperature, cleaning equipment surfaces, checking lubrication system oil level and quality, and checking diaphragm condition. Lubrication system monitoring requires checking lubricating oil level, pressure, and temperature; crankcase oil level should be maintained within the range indicated on the oil level gauge. Operating parameter monitoring requires real-time monitoring of parameters such as pressure, temperature, and exhaust volume via the control panel.
Regular maintenance includes changing the lubricating oil and cleaning or replacing the oil filter every 2000 hours of operation; checking the piston ring and cylinder liner clearance every 8000 hours. Valve and seals should be checked for sealing performance every 6 months, and carbon deposits or impurities should be cleaned. O-rings, gaskets, and other seals should be regularly inspected for wear. The cooling system requires regular checks of cooling water flow and temperature, ensuring the drain temperature does not exceed 40°C; the cooler should be cleaned of scale every 8000 hours.
Troubleshooting guidelines include checking cylinder oil pressure, intake/exhaust valves, and pressure regulating valves when exhaust pressure is abnormal. When encountering oil circuit malfunctions, check the leak valve's sealing, the compensating oil pump's operating status, and the pressure regulating valve's wear. Diaphragm rupture is usually caused by media corrosion, fatigue damage, or foreign object impact. Other common problems include abnormal output pressure, excessive temperature, excessive noise, and media leakage.
The diaphragm is a core, easily damaged component of the diaphragm compressor and requires regular inspection and replacement. If the diaphragm ruptures, the machine must be stopped immediately for replacement. The replacement process includes releasing hydraulic oil from the cylinder, disassembling the cylinder body, installing a new diaphragm, and adjusting the compressor. Diaphragm lifespan is affected by factors such as operating pressure, temperature, gas cleanliness, and start-stop frequency, typically lasting several thousand hours. Professional maintenance recommendations include providing professional training to operators and establishing detailed maintenance records. The equipment operating environment must be kept clean, and the cooling water must be drained after shutdown in winter. Commonly used spare parts such as diaphragms, seals, and valves should be kept in stock.
