Waterjet 101 -Mobile Waterjet Systems

Mobile Waterjet System

A mobile waterjet system typically includes a waterjet pump, waterjet cutting or blasting tool and supporting equipment including a water supply tank, control box and abrasive hopper if using abrasive waterjet.

Mobile Intensifier Pump

 
The mobile intensifier pump produces the ultra high pressure (UHP) water needed for the water tools. The pump can be diesel or electric powered and rated for 36,000 psi (2500 bar) or 55,000 psi (3800 bar).
 

Water Tools

Water tools are used to clean or cut material. All water tools require support equipment. The type of support equipment varies with the type of water tool.
 

Support Equipment

Support equipment includes things like a water tank to supply the mobile pump, an air compressor to operate a water tool, an abrasive distribution system for cutting tools, and control boxes to turn the UHP
water/air on or off to the water tool.
 

Cleaning Tools

Cleaning tools are used to strip material from a surface and prepare it for resurfacing. Cleaning tools include the following:
 
  • Pneumatic Lance - a hand-held tool with a single nozzle to clean small-sized areas.
  • GyraJet - a hand-held tool that uses a rotary manifold to clean medium-sized areas.
  • Deckblaster - a lawn mower style tool that uses a spray bar to clean large-sized areas.

Cutting Tools

Cutting tools are used to cut through material. Cutting tools are equipped with an abrasivejet. Cutting tools include the following:
 
  • Ultra Lite Lance - a hand-held tool that directs an abrasive water stream to cut material.
  • Spyder Abrasivejet - a tool that follows a track to direct an abrasive water stream in a linear motion to cut material.
  • Pipe Cutter - a tool that follows a track to direct an abrasive water stream to cut pipes.

Cut Without Heat or Flames

Jet Edge waterjets cut without heat or flames and can be used in hazardous environments. The cold-cutting process also elimates Heat Affected Zone (HAZ).  Risk of fatigue failure resulting from process induced thermal stressing and associated material structural change is minimized.

No Sharpening Required

Unlike conventional cutting tools, waterjets cut with a supersonic stream of water that never dulls. With waterjet, you will never need to shut down to sharpen or clean blades.

Minimize Dust and Toxic Fumes
The practical elimination of airborne dust particles, smoke, fumes, and contaminates from cutting materials such as asbestos and fiberglass greatly improves the work environment and reduces problems arising from operator exposure.

Near Zero Lateral Cutting Force

Jet Edge waterjet systems reduce fixturing costs plus avoid excessive stress to finished parts. Also, minimal lateral force simplifies material handling and allows cutting close to material edges.

Minimize Dust and Toxic Fumes
The practical elimination of airborne dust particles, smoke, fumes, and contaminates greatly improves the work environment and reduces problems arising from operator exposure.

Environmentally Friendly

Waterjets produce no hazardous waste, reducing waste disposal costs. Waterjets use very little water (a half gallon to approximately one gallon per minute depending on cutting head orifice size). Waste water usually is clean enough to filter and dispose of down a drain.  The garnet abrasive is a non-toxic natural substance that can usually can be disposed of in a landfill. Waterjets also are ideal for use in sensitive marine environments and can be attached to a customer-supplied industrial vacuum system.
