Correlation check: Verify that the cooler and the lubrication system are unobstructed to prevent premature damage to the temperature control kit due to blockage by other components. After replacement, it is recommended to shorten the initial oil change interval to ensure system cleanliness. The normal operation of the constant temperature kit directly affects the lubrication effect and lifespan of the air compressor. When replacing it, strictly follow the technical manual of the corresponding model.

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.

Key points for replacement and installation: Accessory matching: It is necessary to use the original Atlas Copco connectors to ensure that the thread specifications (such as diameter, pitch, and length) are fully compatible with the MPV end caps of the corresponding model (the MPV specifications for different series of air compressors may vary). Sealing treatment: During installation, wrap sealing tape (such as PTFE tape) around the threads or apply sealant to ensure airtightness at the connection point and prevent leakage. Tightening specifications: Use the appropriate tools to tighten according to the specified torque to avoid over-tightening which may cause thread slippage or end cap deformation, and under-tightening which may lead to leakage. Interlock check: After replacement, check whether the relevant pipelines (such as the pressure sensor pipeline) are unobstructed to ensure that the pressure signal is normally transmitted to the control system.

Maintenance suggestions for the regulating valves of Atlas Copco air compressors: Regularly clean the interior of the valves to remove oil stains and impurities (especially the intake regulating valve which is prone to dust influence). Replace the seals and wear parts (such as diaphragms, springs) according to the manual schedule. Calibrate the pressure setting values to ensure they match the system requirements. In case of faults, prioritize replacing the original factory-regulated valves (such as Atlas Copco-specific parts) to avoid system instability due to size or performance mismatch.

Notes on Replacement and Selection Original Factory Parts Preferred: Atlas Copco's gaskets have strict size and material standards. When replacing, it is recommended to use original factory parts to ensure a perfect fit with the connection area. Material Matching: Select gaskets of the corresponding material based on the medium, temperature, and pressure at the installation location. Avoid rapid failure due to improper material selection. Installation Specifications: Clean the connection surface, remove oil stains, rust, and residues of the old gasket. Ensure the gasket is placed correctly , and if necessary, apply a small amount of sealant on the gasket surface . Tighten the bolts evenly according to the specified torque to avoid over-tightening and damaging the gasket or under-tightening and resulting in poor sealing.

Installation requirements for replacement and maintenance instructions: This operation should be carried out by professional technicians to ensure that the installation of the gears in the axial and radial directions is accurate, and the meshing clearance complies with technical standards. Before installation, the mating surfaces should be cleaned, and any damage to the shaft diameter, keyways, etc. should be checked. If necessary, repairs should be made. Lubrication guarantee: After replacement, check if the lubrication path is unobstructed to ensure that the meshing part of the gears is adequately lubricated. After the first start-up, monitor the temperature and noise to ensure normal operation. Interlock check: After replacing the gears, it is recommended to simultaneously check the condition of the mating gears, bearings, and other related components to avoid premature damage to the new gears due to the wear of other components.
