Working principle of marine airbags

Marine airbags, as an important ship auxiliary equipment, play a vital role in the launch, discharge and displacement of ships. It can not only simplify the operation process, but also greatly reduce costs and improve work efficiency. This article will explore the working principle of marine airbags in detail, from the inflation process to the specific mechanism of supporting the hull, to fully understand the application of this innovative equipment in the shipbuilding industry.

  1. Basic structure of marine airbags
    Marine airbags are usually made of high-strength rubber and synthetic fiber materials, with the following main parts:
    A. Outer rubber: Provides wear-resistant and tear-resistant protection to ensure the durability of the airbag in harsh environments.
    B. Reinforcement layer: Consists of multiple layers of synthetic fiber fabric to enhance the compressive strength and toughness of the airbag.
    Inner rubber: Prevent gas leakage and ensure the airtightness of the airbag under high pressure.
    C. Air valve: Used for inflation and deflation to control the pressure inside the airbag.
  2. Inflation process of marine airbags
    Inflation is the first step in the work of marine airbags. By controlling the air pressure inside the airbag, its shape and hardness can be adjusted to meet different operating requirements. The specific inflation process is as follows:
    A. Preparation: Before use, check whether the appearance of the airbag is damaged, whether the air valve is normal, and ensure that the inflation equipment is intact.
    B. Connect the inflation equipment: Connect the inflation equipment to the air valve of the airbag to ensure that the connection is tight and there is no leakage.
    C. Start inflation: Start the inflation equipment and gradually inflate the airbag. During the inflation process, it is necessary to monitor the pressure inside the airbag to ensure that it is within the safe range.
    D. Reach the predetermined pressure: According to the specific operating requirements, inflate the airbag to the predetermined pressure. Under normal circumstances, the pressure of the airbag should be maintained between 0.2-0.8MPa.
    E. Close the air valve: After the inflation is completed, close the air valve, disconnect the inflation equipment, and check the airbag again for leakage.
  3. The principle of marine airbags supporting the hull
    When supporting the hull, the marine airbag provides sufficient buoyancy and support through the high-pressure gas inside it, so that the hull can move or park smoothly. The specific working principle is as follows:
    A. Buoyancy: After the marine airbag is inflated, the buoyancy generated by the internal gas can partially or completely support the weight of the hull, allowing it to move smoothly in water or on land.
    B. Pressure distribution: The airbag distributes the weight of the hull evenly on multiple airbags through its own elasticity and flexibility, avoiding damage to the hull caused by a single pressure point.
    C. Rolling displacement: During the displacement of the ship, the airbag can be used as a rolling fulcrum, and the hull can be moved smoothly to the predetermined position by continuously rolling the airbag.
    D. Stable support: The marine airbag forms multiple support points under the hull. By adjusting the pressure and position of the airbag, the hull can be stably supported to ensure the safety of the hull during displacement and parking.
