China atlas copco spares Manufacturer, Supplier, Factory

The oil filter element of Atlas Copco air compressors (Common Problems and Failure Causes) The filter element gets clogged prematurely Reasons: Excessive environmental dust (unfiltered intake air), excessive oil addition or mixing of different brand oils leading to emulsification, increased internal wear . Treatment: Improve environmental cleanliness, standardize oil usage, inspect worn components. Poor filtering effect Reasons: Using inferior filter elements , seal ring not properly aligned during installation , bypass valve always open. Treatment: Select original factory or high-quality aftermarket filter elements, ensure proper installation sealing, regularly check bypass valve function. Filter element rupture Reasons: Installation too tight, abnormal system pressure increase, insufficient strength of filter element material. Treatment: Standardize installation torque, check oil pressure control system, replace with qualified filter element.

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.

Faults and Replacement Suggestions: Common Faults and Handling: Contact Erosion: Manifested as poor contactor engagement, severe overheating, or failure of the main circuit. Replace the contactor to prevent the motor from operating without phases; Winding Burnout: Usually caused by abnormal voltage or winding aging, resulting in the contactor unable to engage. Check the winding voltage and replace the original part; Stuck and Strange Noise: Caused by dirty iron core or failed spring. May lead to contact adhesion. Replace immediately to prevent the equipment from losing control. When replacing, please note: Power off and confirm that the main circuit voltage has been disconnected. When connecting, distinguish between the main contact (high-power circuit) and the auxiliary contact (control circuit). Secure the connection terminals to prevent loosening and overheating.

Maintenance precautions for the oil filter and air filter components of Atlas Copco air compressors: When replacing, clean the interior of the filter housing to avoid secondary contamination by residual impurities. When installing, ensure a proper seal to prevent air leakage (for the air filter) or oil leakage (for the oil filter). It is recommended to inspect both the air filter and the oil filter simultaneously. If one of them is severely clogged, it may indicate an abnormality in the environment or the system (for example, clogged air filter may lead to insufficient air intake, indirectly exacerbating oil contamination).
