Huge Carrying Ability Ship Launching Pneumatic Rubber Airbags

Marine Rubber Airbags

Air bag for heavy lifting and transportation and ship launching is an progressive merchandise with impartial intellectual house rights in China. At current, it has been extensively used in ship launching, caisson lifting and transportation, managing of other large objects, and floating assist of underwater installation engineering. The application of marine air bag is much less minimal by the internet site, and does not require big-scale mechanical equipment, so it can shorten the engineering time period and preserve a whole lot of cash. Soon after far more than twenty several years of deveXiHu (West Lake) Dis.Hu (West Lake) Dis.ment and practice, it has been proved that this merchandise has the traits of basic safety, higher effectiveness, eco-friendly environmental protection, fleXiHu (West Lake) Dis.bility and so on.

The generation and application of marine airbags mostly refer to two sector stXiHu (West Lake) Dis.Hu (West Lake) Dis.rds: CB / t3795 quotairbags for ship discharge and launching quot and CB / T3837 quottechnical requirements for higher discharge and launching of ship airbags quot.

In the simple requirements and evaluation approaches for production circumstances of shipbuilding EPTrprises formulated by the Fee of science, technology and sector for nationwide defense, air bag launching is incEPTd as an authorized launching method for the first time, and it is stipulated that course II and class I EPTrprises are authorized to use air bag launching method. Meanwhile, corresponding requirements are set EPT for the equipment using air bag launching.

Maintenance of Maritime Airbags

When the air bag is not utilized for a EPT time, it should be washed and dried, crammed with talcum powEPTinside and outside, and placed in a dry, amazing and ventilated place indoors. The air bag shall be stretched out and placed horizontally, and no large objects shall be piled on the air bag.

Preserve the air bag absent from warmth resources.

The air bag should not be in make contact with with acid, alkali, grease and natural solvent.

Fix of Maritime Airbags

The damage types of marine airbags can be EPTly divided into EPTitudinal cracks (cracks extending aEPT the size of airbags), transverse cracks (cracks extending aEPT the circumference), and nail holes (incXiHu (West Lake) Dis.Hu (West Lake) Dis. disc-shaped damages with a diameter of much less than ten cm).

The procedure measures are as follows:

1) Mark out the scope of repair as the boundary of the poEPTd surface area. The scope of fix need to be prolonged close to the crack, and no hidden injury must be skipped. The expansion variety may differ in accordance to the type and hurt range of the airbag, which is generally 18-20cm for three levels, 20-22cm for 4 levels, 22-24cm for 5 levels and 24-26cm for six layers. Laying of wire material with EPTitudinal crack.

2) Grind the surface of the repaired portion until the fiber thread is exposed, but do not hurt the fiber line.

3) For EPT cracks, the twine thread must be utilised to sew the EPT cracks. The distance amongst needle holes and cracks is about 2-3cm, and the distance in between stitches is about 10cm.

4) Clear the area to be fixed with gasoline and awesome dry.

5) Implement a layer of glue. Mucilage is manufactured from raw rubber and soaked in gasoline. The weigEPT ratio of raw rubber to gasoline is normally one:five, and it need to be a bit thinner when coating the 1st layer (the weigEPT ratio of raw rubber to gasoline can be one:eight). Soon after the initial layer of mucilage is dried, apply a a bit thicker glue and dry it.

6) Seal the crack with the raw rubber strip with thickness of one mm and width of one cm bigger than the crack.

7) Brush the gasoline and dry.

eight) For EPTitudinal cracks, very first implement a layer of hanging twine cloth perpendicular to the crack path with a width of about 10cm. For transverse cracks and nail holes, step (10) can be operated right.

9) Brush the gasoline and dry.

ten) Lay a layer of hanging cord material pXiHu (West Lake) Dis.Hu (West Lake) Dis.lel to the EPTitudinal direction. The lap spot around the crack ought to be a lot more than 5cm, and the edges ought to be lower into rounded corners

eleven) Brush the gasoline and dry.

12) Lay a layer of hanging rubber cord material obliquely. The path of the cord must be the very same as that of the diagonal wire (or reinforcing fiber) in the bag wall. The lap area close to shall be 1cm larger than that of the preceding layer of wire material, and the edges shall be lower and pasted into rounded corners

13) Brush the gasoline and dry.
