The Applications Of WP Series Marine Air Compressor

  • Starting the Main and Auxiliary Engines:
    The WP compressor provides compressed air required for engine starting. It delivers the necessary air pressure to initiate the combustion process in both the main and auxiliary engines, ensuring their reliable and efficient operation.
  • Manipulation of the Reversing Mechanism:
    The compressor controls the reversing mechanism of the vessel. It supplies compressed air to engage or disengage the reversing mechanism, allowing for smooth and precise maneuvering of the ship, particularly during navigation and docking procedures.
  • Control of Shafting Pneumatic Clutch:
    In marine propulsion systems, the WP compressor plays a vital role in controlling the pneumatic clutch of the shafting. By supplying compressed air to the clutch mechanism, it enables seamless engagement and disengagement of the clutch, facilitating efficient power transmission between the engine and the propeller.
  • Filling Pressure Tanks and Hydraulic System:
    The compressor is responsible for filling pressure tanks, which store compressed air for various pneumatic systems onboard the vessel. Additionally, it assists in maintaining the required hydraulic system pressure by supplying compressed air to the hydraulic system’s pressure oil tank, ensuring smooth operation of hydraulic equipment and systems.
  • Purging and Cleaning:
    The WP compressor supports purging operations by supplying compressed air to purge parts, pipes, and bottom valves, ensuring the removal of contaminants and maintaining system cleanliness. It also aids in cleaning the boiler flue, ensuring efficient heat transfer and optimal boiler performance.
