China spare parts for air compresor atlas copco Manufacturer, Supplier, Factory

During use, it is necessary to follow Atlas Copco's recommendations to regularly inspect and replace the air filter components. Generally, when the operating environment of the equipment is relatively clean, the replacement cycle can be appropriately extended; if the environment is dusty, the replacement cycle should be shortened to ensure the normal operation of the air compressor and the quality of the compressed air. When replacing, it is necessary to select qualified accessories certified by us to ensure the filtering performance and equipment compatibility.

Basic working principle A three-phase induction motor generates a rotating magnetic field by connecting to three-phase alternating current and passing it through the stator windings. The rotor cuts the magnetic lines of force in the magnetic field, generating an induced current, which is then subjected to electromagnetic force and rotates in accordance with the magnetic field (the rotational speed is slightly lower than that of the rotating magnetic field, and there is a slip rate). The electrical energy is converted into mechanical energy to drive the compression mechanism of the air compressor (such as pistons, screws, etc.) to operate. Adaptation features

The air compressor oil filter is a key component of the lubrication system of an air compressor. It is mainly used to filter out impurities, particles and contaminants from the lubricating oil, ensuring that the oil entering the compressor meets the cleanliness standards, thereby protecting the internal components of the compressor (such as bearings, gears, rotors, etc.) from wear and damage, and extending the service life of the equipment. Working principle Physical interception: Through the microporous structure of the filter paper or filter element, particles larger than the pore diameter are mechanically filtered out. Adsorption effect: Some filter element materials can adsorb colloids and moisture, thereby enhancing the filtering effect.

Maintenance for the non-driven side motor components of Atlas Copco oil-injected screw compressors Regular inspection Observe whether there is oil leakage or seepage at the non-driven side end cover ， check for abnormal temperature rise， and use a sound detector to determine if there is any abnormal noise. Check the tightness of the end cover bolts to ensure reliable sealing. Bear maintenance Replace the bearing lubricating grease according to the cycle specified in the motor manual， clean the bearing chamber， and avoid mixing new and old lubricating grease. When replacing the bearings， ensure the model is matched， and install them using heat fitting or special tools to avoid damaging the bearings by knocking. Sensor calibration Regularly calibrate the temperature sensor to ensure detection accuracy； check if the connection terminals are oxidized or loose， and clean or tighten them if necessary. Heat dissipation maintenance

Common Problems and Maintenance Suggestions Oil deterioration: manifested as darker color (turning brown or black), the appearance of sludge, emulsification (becoming milky white). This is mostly caused by high-temperature oxidation, water contamination or pollution. It is necessary to replace the oil immediately and investigate the causes (such as cooling system failure, breathing device blockage). Abnormal increase in fuel consumption: may be due to the failure of the oil separator, clogging of the return oil pipe or damage to the sealing parts. It is necessary to check the relevant components and replace them. Selection Principles: Only Atlas Copco original oil or certified equivalent oil products must be used. Inferior oil will lead to severe carbon deposits, accelerated bearing wear, and even cause major failures such as engine stalling.

For the maintenance of UD 9 + from Atlas Copco, it is recommended to replace the filter elements at the specified intervals as per the equipment manual. During the replacement process, it is necessary to first depressurize the system and have it operated by professionals to ensure safety and installation quality.
