China atlas copco 75 hp air compressor Manufacturer, Supplier, Factory

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 8000-hour maintenance kit for the Atlas Copco IMD260 air compressor may vary slightly in specific component quantity and model depending on the supplier or original factory providing the maintenance kit. For accurate kit contents and detailed information, it is recommended to contact us directly, providing the specific model and serial number of the air compressor to obtain the most precise maintenance kit-related materials.

Discharge piston: Performs reciprocating motion under the drive of air pressure or oil pressure, directly acting on the intake valve assembly to control the opening/closing state of the valve. Spring: Provides a restoring force. When the discharging signal disappears, it pushes the discharge piston back to its initial position, allowing the compressor to return to the loaded state. Sealing ring / guide ring: Ensures the sealing performance and motion stability of the piston within the cylinder, preventing medium leakage and reducing wear. Push rod or connecting rod: Connects the discharge piston with the intake valve, transmitting motion to achieve the linkage control of the valve.

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

Maintenance Points Regularly replace the filter element: Based on the usage environment and operating time (generally recommended every 2,000-4,000 hours) , replace the filter element to avoid increased pressure loss and reduced filtering effect due to blockage. Pressure difference monitoring: Some models are equipped with a pressure difference indicator. When the filter element becomes clogged to a certain extent, it will give a prompt, and it is necessary to replace it in time to ensure the normal operation of the system. Sealing check: Regularly check the interface sealing condition of the filtering component to prevent unfiltered compressed air from leaking into the downstream system. If you need to purchase filter elements or want to know about specific compatible models, it is recommended to refer to the PD295 filtering component technical document provided by Atlas Copco officially, or provide the detailed model of the air compressor (such as GA37, GA55)

If you need to purchase Atlas Copco products or replace the screws of Atlas Copco air compressors, it is recommended that you select products with matching specifications and performance based on the model of the air compressor, specific components, and the regulations in the equipment manual, in order to ensure the safe and stable operation of the air compressor.
