China atlas copco oil free air compressor Manufacturer, Supplier, Factory

Coupling replacement: When replacing the coupling, it is recommended to simultaneously check the condition of the motor and the main machine bearings, as coupling failures may be caused by shaft displacement resulting from bearing wear.

The Atlas Copco C242 screw air compressor discharge valve repair kit is applicable for maintenance recommendations. Applicable models: Specifically designed for the C242 screw air compressor model. It is necessary to confirm the specific production batch and discharge valve model of the equipment (this can be verified through the equipment serial number or part number). Replacement Timing： When there are abnormal compressor pressure， significant pressure remaining during discharge， slow loading response or abnormal air leakage sounds， etc.， it may indicate that the discharge valve needs maintenance or replacement of components. At this time， this kit can be used for maintenance. Installation note： It is recommended to operate by professional technicians according to the original factory maintenance manual to ensure correct assembly and avoid secondary faults caused by improper installation.

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

There are probably several common faults of air compressors, and at the same time, these faults have some corresponding solutions:

Atlas Copco 2903775400=1625775400 Notes for Attention Choosing the original factory oil filter (such as the products corresponding to these two numbers) can ensure that the filtration efficiency, size accuracy and equipment are fully matched, avoiding the risk of host wear caused by the failure of inferior filter elements. If there is a replacement relationship between the numbers, when replacing, you can directly use the new number parts, and their performance and compatibility are the same as the old numbers.

Maintenance and Replacement Suggestions for Atlas Copco Oil Coolers Regular Cleaning: For air-cooled coolers, clean the dust and oil stains on the fins regularly. For water-cooled ones, check if the water channels are blocked or clogged to ensure the cooling effect. Leak Check: During daily inspections, observe if there are oil stains on the surface and interface of the cooler. If leakage is detected, replace the sealing parts or the entire kit promptly. Replacement Timing: When the cooler shows severe corrosion, large-scale damage to the fins, or internal blockage causing abnormal oil temperature rise , it is recommended to replace the entire kit. Preferentially use Atlas Copco original accessories to ensure compatibility with the unit and cooling performance. The reliable operation of this kit directly affects the energy consumption, stability, and service life of the oil-free air compressor, and is an important guarantee for maintaining the efficient operation of the unit.
