Hydro jetting and Hydro blaster equipment is used to direct high pressure streams of water against a surface to clean or cut the material. The steams of water released by hydro jetting and hydro blasting equipment can exceed 10,000 psi. hydro jetting and hydro blaster equipment is used for cleaning or demolition of products made of metal, wood, concrete, stone, plastic, glass or other building materials.
Specific components within a hydro jetting or hydro blaster equipment system include abrasive injectors, pressure generators, blast cabinets or booths, water guns, and water tanks. Plunger-type intensifier pumps are commonly used to generate high pressure water for water jet cutting, wet or water abrasive blasting and non-abrasive pressure washing or rinsing. Crankshaft driven plunger pumps are also used for pressure generation.
Usually crankshaft driven plunger pumps may be more efficient in electrical energy costs compared to intensifiers, but at high pressures (>20,00 psi, 137 bar) seals must be periodically replaced. Crankshaft driven plunger pumps also provide a virtually ripple free pressure source in comparison to intensifiers. An accumulator may be required to smooth out pressure fluctuations if an intensifier pump is used. In air based blast or jet systems, air compressors are typically used to generate pressure which add heavy running cost.
Water guns or lances are the apparatus within hydro jetting and hydro blaster equipment that directs the stream of water through a nozzle and at the appropriate region of the work piece.
The water tank or hopper is used for storage of water, cleaning agents, blasting media or abrasive-water slurry mixtures.
