China atlas copco air compressors Manufacturer, Supplier, Factory

The 4000-hour maintenance kit of Atlas Copco is applicable in the following scenarios: It is mainly used for regular preventive maintenance when the compressor operates for about 4000 hours. It is one of the recommended maintenance cycles by Atlas Copco, and is particularly suitable for industrial scenarios where continuous operation of the equipment is required. By regularly replacing the components within the kit, it can effectively prevent the decline in compressor efficiency, increase in energy consumption, or equipment failure and shutdown caused by filter failure, oil aging, or poor sealing.

Troubleshooting and Replacement Suggestions: Common Issues and Solutions: Stalling or Leakage: Causes unstable pressure and increased energy consumption. It is recommended to disassemble and clean or replace directly (it is suggested to replace the entire set to avoid matching issues between new and old components). Reduced Adjustment Precision: Mostly due to wear of sensors or valve cores. Replacement of the original kit is required and recalibration is necessary. Installation Tips: After replacement, parameter matching through the controller (such as setting pressure upper and lower limits) is necessary to ensure normal system linkage.

Maintenance recommendations for the oil filter of Atlas Copco screw air compressors: Replacement cycle: Under normal operating conditions, replace the filter once every 2,000 - 3,000 hours. In harsh environments (such as high dust and high temperature), this period should be shortened to 1,500 hours. Synchronous operation: When replacing the filter element, also simultaneously discharge the settled oil at the bottom of the oil tank (containing a large amount of impurities) and refill the oil to the specified level. Selection requirements: It is necessary to select original factory or certified filter elements that match the compressor model to avoid equipment damage due to size mismatch or insufficient filtration accuracy. Effective maintenance of the oil filter can significantly reduce the wear rate of the screw main unit and is a key aspect of the daily maintenance of the compressor unit with low cost and high efficiency.

The Importance of the Air Intake Valve in Atlas Copco Air Compressors and Its Connection to Energy Saving The adjustment accuracy of the intake valve directly affects the energy consumption of the air compressor: If the intake valve is not closed tightly , the air compressor will still consume additional power during unloading (about 30% - 50% of full load), and long-term operation will significantly increase electricity costs. The slide valve type and other continuously variable intake valves can adjust the intake volume in real time according to the actual gas consumption, and are 10% - 20% more energy-efficient than traditional butterfly valve types . In summary, the intake valve is the "breathing valve" of the air compressor. Its performance and condition are crucial to the operating efficiency, energy consumption, and stability of the equipment. Regular maintenance and correct selection are the key to ensuring the economic operation of the air compressor.

Notes for Attention Regular inspection: The pressure relief valve should be subject to regular functional checks and calibrations to ensure it operates properly in case of abnormal pressure, preventing failure due to issues such as valve core jamming. Replacement of genuine products: When replacing the pressure relief valve, it is recommended to choose original Atlas Copco spare parts or products from authorized official channels to ensure compatibility with the equipment and safety. Professional installation: The installation process should be carried out by professional technicians to ensure reliable valve connection and sealing, and to meet the pressure specification requirements of the equipment.

I. Working Principle The safety valve is designed based on the principle of force balance. It mainly consists of a valve seat, a valve core, a spring, and a regulating mechanism. When the system pressure exceeds the spring's preload force, the valve core is pushed up, and the medium (compressed air) is discharged; when the pressure drops to the return seat pressure, the spring pushes the valve core back to its original position, closing the valve. Key parameters: Opening pressure (set pressure): The pressure at which the valve begins to open, usually 1.05 to 1.1 times the working pressure. Emission pressure: The pressure when the valve reaches its maximum opening height, generally ≤ 1.1 times the opening pressure. Return seat pressure: The pressure when the valve is closed, usually 10% to 15% lower than the opening pressure. Sealing pressure: The maximum pressure at which the valve maintains sealing, generally 90% of the opening pressure.
