China Atlas Copco 0574800274 Manufacturer, Supplier, Factory

Gear transmission of the air compressor body: For Atlas Copco G/GA and other oil-injected screw compressors, "high-performance gear drive" is commonly used. The motor drives the main unit through a gearbox for speed increase, which is a transmission structure rather than a "gear motor".

Key points for replacement and installation Shut down the equipment, release pressure and cool down to normal temperature. Close the inlet / return oil valves to prevent hot oil from spilling out. Record the path of the pipeline and the sequence of the joints, and keep the identification of the old parts. Clean the interfaces and installation surfaces. Replace the O-ring / sealing parts if necessary. Tighten the joints according to the specified torque; avoid excessive bending and stretching of the rubber hose; firmly fix the rigid pipe to prevent vibration wear. Before starting the equipment, check the oil level and sealing performance. After operation, recheck the pressure drop and leakage.

1. loading solenoid valve ‌ : It adopts a two-position three-position normally closed structure and controls the on-off of the pipeline from the oil and gas tank to the intake valve through PLC instructions. When powered on, allow compressed air to enter the intake valve pipeline and open the intake port. When power is cut off, cut off the air passage and expel the residual air in the cylinder, then close the air inlet 2. Vent solenoid valve ‌ : Open the valve for two positions and two normal positions to ensure that the pressure in the oil and gas tank of the air compressor remains at around 0.2MPa when it is no-load. When the machine is shut down and unloaded, cut off the power and release the gas to the intake filter to prevent excessive pressure

Key points for replacement and maintenance: Selection matching: Use the original factory connectors of the corresponding model. Confirm the interface specifications, pressure grade and material. Avoid leakage or connection failure due to mismatched dimensions. Installation guidelines: Pneumatic/oil circuit connectors: Wrap sealing tape or replace the new seal, tighten according to the specified torque, avoid over-tightening which may cause thread damage. Electrical connectors: Ensure the pins are aligned, prevent damage caused by forced insertion or removal, tighten the locking structure . Regular inspection: During daily maintenance, check if the connectors are loose, corroded or overheating . Address abnormal situations promptly.

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.

6229031700 The non-return valve C77 of the oil-injected screw compressor from Atlas Copco reduces the impact of the backflow airflow on the internal components of the compressor, such as rotors and bearings, thereby extending the service life of the equipment.
