I. Daily Maintenance (Daily Must-Do)
1. Condensate Drainage: After shutting down the machine daily, promptly drain the condensate from the air receiver, filters, and oil-gas tank of the OSMAN screw air compressor. Avoid internal corrosion of the equipment and emulsification of lubricating oil caused by residual condensate, ensuring the long-term stable operation of the OSMAN air compressor and giving full play to its energy-saving advantages.
2. Oil Level and Oil Quality Check: Check the oil level of the OSMAN special lubricating oil. Ensure the oil level is between 1/2 and 2/3 of the sight glass. Observe the oil quality; if the oil becomes turbid, discolored, or contains impurities, replace the OSMAN original special lubricating oil in a timely manner to prevent damage to the main engine rotor caused by inferior oil products.
3. Clean the Surroundings: Keep the area around the OSMAN air compressor clean and free of obstacles. Ensure unobstructed ventilation to avoid affecting the heat dissipation effect of the equipment and ensure the stable operation of the air compressor's performance.
4. Leakage Inspection: Inspect the OSMAN air compressor and its connecting pipelines regularly to check for air, oil, or water leaks. Handle any leaks promptly to avoid affecting the normal air supply and increasing energy consumption.
II. Regular Maintenance (Performed Every 2000 Operating Hours)
1. Filter Replacement: Replace the OSMAN original air filter, oil filter, and oil-gas separator core every 2000 operating hours. For environments with heavy dust, shorten the replacement cycle to ensure the air intake is clean and the oil-gas separation effect is optimal, protecting the main engine from wear.
2. Lubricating Oil Replacement: Replace the OSMAN original special lubricating oil every 2000 operating hours. When replacing the oil, clean the oil circuit to remove residual impurities and ensure the smooth operation of the lubrication system.
3. Cooling System Maintenance: Clean the surface of the cooler and radiator of the OSMAN air compressor every 2000 operating hours to remove dust and oil stains. For water-cooled models, check the water circuit for unobstructed flow and remove scale to ensure good heat dissipation effect.
4. Component Inspection and Fastening: Check the key components of the OSMAN air compressor every 2000 operating hours, including air intake valves, oil return pipelines, and electrical lines. Tighten loose parts in a timely manner and replace aging seals or damaged components.
III. Long-Term Shutdown Maintenance (Shutdown for More Than 15 Days)
1. Shutdown Preparation: Let the OSMAN screw air compressor run idly for 3-5 minutes, unload the pressure, cut off the main power supply, and close the air intake and exhaust valves to avoid damage to the main engine and electrical system due to pressure buildup.
2. Internal Protection: Drain all compressed air and lubricating oil in the OSMAN air compressor system, clean the residual impurities in the oil-gas tank and pipelines, and apply anti-rust oil to key components to prevent rusting.
3. External Protection: Cover the OSMAN air compressor with a dust cover to prevent dust and debris from entering the equipment. Keep the machine room dry and ventilated to avoid moisture damage to electrical components.
IV. Maintenance Notes
1. Before performing any maintenance operations on the OSMAN air compressor, cut off the power supply, release the system pressure, and hang a "No Operation" warning sign to ensure the safety of maintenance personnel.
2. All maintenance accessories (filters, lubricating oil, seals, etc.) must use OSMAN original products to avoid equipment failures caused by incompatible accessories.
3. Non-professionals are not allowed to disassemble or overhaul the core components of the OSMAN air compressor. For complex maintenance operations, contact OSMAN professional after-sales personnel for handling.
4. Keep detailed maintenance records, including maintenance time, maintenance items, and replaced parts, to facilitate subsequent traceability and equipment life management.
