Underwater Breaker Operation Guide: Air Line & Isolation

It is possible to operate hydraulic breakers in port construction, canal deepening, or bridge pillars. However, if you submerge a standard breaker, it will be destroyed in seconds due to the "water hammer" effect.

1. Underwater Kit & Air Line

Water must be prevented from entering the breaker. For this:

• Compressor Connection: Constant compressed air is supplied from the top. This air pushes water out and prevents ingress.
• Underwater Kit: Special sealing elements and air intake ports are added.

2. Precautions

The compressor must be turned ON before entering the water and turned OFF after exiting. Even a drop of water inside will cause corrosion on the piston and cylinder.

Frequently Asked Questions (FAQ)

Q: What happens if I work without an underwater kit?
A: The breaker will fail instantly due to the "Water Hammer" effect. Since water is incompressible, the piston impact will burst the cylinder and seals. Also, seawater causes corrosion.

Q: How much air pressure is needed?
A: The compressor air pressure just needs to be higher than the water pressure at depth. Usually, a continuous stream of bubbles indicates that water is being kept out.
