Replacement and Maintenance Suggestions: When the bushing shows excessive wear, scratches, cracks, or if the clearance between the bushing and the shaft exceeds the limit, it should be replaced immediately. Otherwise, it may cause wear on the shaft neck, increased vibration, or abnormal noise from the equipment. When replacing, use original factory parts and ensure that the surface of the shaft and the bearing housing are cleaned before installation. If necessary, perform size checks according to the manual requirements. During installation, avoid knocking the bushing to cause deformation. If necessary, use professional techniques such as hot assembly to ensure the mating accuracy.

Atlas Copco Gear Trial Run and Inspection Preliminary Inspection Manually rotate the gear shaft to feel if the rotation is smooth, and check for any sticking, abnormal noise or eccentric vibration. Check if the lubrication path in the gearbox is unobstructed, and add gear oil to the standard level as per the regulations. No-load Trial Run Connect the power supply and conduct a short-term (5-10 minutes) no-load operation. Listen for any abnormal noises (such as metal friction sounds, high-frequency squeals) from the gearbox. After stopping the machine, check the temperatures of the bearings and gears (should not exceed the ambient temperature by 40°C), and observe for any oil leakage. Load Test Gradually load to the rated pressure and run for more than 30 minutes. Recheck the noise, temperature and sealing conditions, and confirm there are no abnormalities.

Attention Points for Lubricant Selection of Atlas Copco's GA and GX Series Air Compressors Compatibility: Non-original lubricants may not be compatible with the equipment material or the original residual lubricants, leading to problems such as sludge formation and seal aging. It is recommended to avoid mixing them. Work Condition Adaptation: Select the appropriate type of lubricant based on the working pressure, temperature, running time, and environmental conditions of the air compressor. Regular Replacement: Even for long-lasting lubricants, it is necessary to regularly check the oil level and quality as per the manual, and replace them on time. At the same time, replace the oil filter to avoid affecting the equipment performance due to deteriorated oil quality. Model Matching: The GA series are mostly large industrial-grade air compressors, while the GX series are more inclined towards small-sized or portable ones.

Atlas Copco confirms the type of lubricating grease Based on the type of air compressor components and operating conditions , select the matching special lubricating grease . It is strictly prohibited to mix different types or grades of lubricating grease . Check the parameters of the lubricating grease: such as applicable temperature range, pour point , and penetration . Atlas Copco cleans the components to be lubricated Stop the machine and ensure the components are completely cooled. Use oil-free cotton cloth or dedicated cleaning agents to wipe the old lubricating grease, oil stains, dust, and metal debris on the surface of the components, especially the key areas such as the bearing seat and the meshing surface of the gears, which need thorough cleaning .

Atlas Copco The air compressor temperature sensor is an important component used for real-time monitoring of the temperatures of key parts of the compressor unit (such as exhaust temperature, oil temperature, and motor temperature, etc.). Its core function is to detect temperature changes and provide data support for the control system, ensuring that the equipment operates within a safe temperature range. At the same time, when abnormal temperatures occur, it triggers protection mechanisms (such as shutdown and alarm) to prevent mechanical failures or safety risks caused by overheating.

Selection and precautions for the oil-water separator of Atlas Copco G series air compressors The oil-water separator should be selected based on the specific model (such as G37, G75) and displacement of the G series air compressor to ensure that the processing capacity matches. It is recommended to use the original Atlas Copco oil-water separator and filter element. Their materials (such as the filter element using high-efficiency fiberglass or polyester materials) and structural design are fully compatible with the G series models, which can ensure separation efficiency and service life, and avoid secondary pollution or excessive pressure loss caused by compatibility issues.
