Maritime Floating Rubber Airbags 1.5m x 20m Heavy Concrete Lifting Airbag
Products introduction
Ship air bag launching technology is on the basis of traditional
launching technology developed, which USES flexible air bags to
replace chute and skateboard,To overcome the many shortcomings of
traditional launching.
Outer Rubber Layer
The outer rubber layer that covers the outside of marine airbag to
protect under layers from abrasion and other external forces. This
compound has sufficient tensile and tearing strength to withstand
any condition and hard usage.
Inner Rubber Layer
The inner rubber layer seals pressurized air inside marine airbags.
Synthetic-Tire-Cord Layer as Reinforcement
The reinforcement cord layers, which are made of
synthetic-tire-cord commonly used in tires, are arranged at ideal
angles to hold the internal pressure and distribute stress evenly.
So they can provide strong efficient reinforcement.
Performance Calculation Principle of Airbags
The bearing capacity of marine airbags was calculated based on the
working pressure, contact area. Herein, working pressure was got
upon the burst pressure and safety working factor.
Because of the flexibility of marine airbag the contact area will
be affected by some terms which include the carried ship condition,
the different position from gravity center during the process of
ship launching and pulling. So the bearing capacity of airbags will
vary as well as the contact area.
The approximate bearing capacity can be calculated as follows:
F=PS
S=π x (D1-D2)/2
Mark:
F: Bearing capacity
P: Inner pressure
S: Contact area
D1: Diameter of airbags when free of loat
D2: Working height of airbags when loaded
