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

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.

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.

Common reference for the accessory numbers of the Atlas Copco WIS series pressure reducing valves: Some models may use the pressure reducing valve with the part number 2901126000 (which requires matching specific pressure parameters)

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.

Installation and Maintenance: Select the corresponding specification of shock absorbers based on the model and weight of the equipment to ensure uniform force application during installation. After long-term use, check if the rubber has aged, cracked or deformed. If the performance deteriorates, replace the original factory parts in time to maintain the shock absorption effect.

Compressors operate in many different types of environment, affecting the inlet air. Impurities, such as dust particles, are mostly invisible to the naked eye. But they can cause damage to the compressor element, reducing its efficiency or even causing failure. They can also make the lubricant age faster and disrupt its capacity to protect metal components.
