Precautions When Inflating Ship Launching Airbags

Ship launching airbags are indispensable equipment for docks and ships. They must be inflated before use. They can withstand heavy loads. As early as thousands of years ago in ancient China, people used cylindrical wood to carry heavy objects. Marine airbags are modern log carrying tools. Depending on the amount of air in the marine airbag, the direction, speed and safety of the ship’s launch will be affected. The inflation of marine airbags is different from that of ordinary balloons. You cannot inflate them casually based on your feelings. You must always observe the pressure gauge and the hull to adjust the inflation amount.

  1. When using the ship launching airbag, the airbag must be inflated to the minimum working pressure, otherwise the ship will be in danger of damage. During the launching process of the ship, the ship will be subject to the support force of the marine airbag, the friction force of the airbag on the bottom of the ship, and the gravity of the ship in three different directions. The inflation pressure of the marine airbag is generally around 120kpa when it is used. The shipyard can adjust the inclination angle of the ship by adjusting the inflation pressure of the marine airbag, so that the component force of the ship’s gravity is slightly greater than the friction force, forming a force suitable for sliding down.
  2. Don’t be too anxious when inflating the marine airbag, otherwise one side of the airbag may bulge due to excessive inflation, while the other side has no reaction, which will also cause the bulging side to burst due to excessive pressure.
  3. The inflation equipment should be selected according to the size of the marine airbag. It is best to choose an air compressor with a capacity of 0.036 cubic meters per minute. The exhaust volume per minute is small, and the inflation time is about 5-10 minutes. In this way, the pressure can be observed frequently. The values ​​in the table will not cause the marine airbag to burst due to instantaneous overpressure.
    High-quality marine airbags can have a long service life, but incorrect inflation is the most dangerous killer of marine airbags. The correct amount of inflation will ensure that your boat can be launched smoothly!
