Pressure jet has achieved
tremendous success on a new feature of Wet
There are a wide variety of surface preparation methods available, such as
solvent cleaning, power-tool cleaning, dry sand blasting etc. But, all
these conventional methods are rarely used because they are time consuming, not
cost effective & provide poor cleaning results & also create
environmental pollution. Nowadays, water sand blasting by high pressure waterjet pump has got wide acceptance in the field of
surface preparation as well as in paint removal & rust Removal. In wet sandblasting, an abrasive material
is mixed with the waterjet to create an abrasive spray. This abrasive spray is
blasted on the surface, which breaks away small pieces of undesirable coating
corrosion or other undesirable substances to create the desired metal finish,
perfect for recoating.
Wet sand blaster is widely used in
engineering, heavy engineering, fabrication, construction and many other
industries for different applications.
HOW WATER SANDBLASTING WORKS?
Start the high pressure system and adjust the water flow and system pressure
with your nozzle selection, pump RPM and Regulating Unloader setting. Open the
trigger on gun to assure system is operating properly.
Place the sand induction probe in the sand supply container. With the trigger
on the gun open, adjust the small valve on the mixing head. The adjustment
creates a vacuum in the sand hose line and starts the flow of sand. The pressure washer sandblaster should be
approximately 12 to 15 inches away from the work surface when the trigger is
opened and the water sandblasting
The angle of attack and distance from the work surface may be varied to
provide the best work speed, while still maintaining the greatest amount of
impact energy. For optimum performance the sand inlet hose should not exceed 25
When the wet sand blasting unit is
operating efficiently, there will be a smooth and continuous flow of sand
through the nozzle. The amount of sand flow is directly related to the vacuum
created in mixing nozzle. The intensity of the vacuum is dependent upon the
liquid velocity of the water.
The pressure and flow rate through the spray nozzle are the factors that
determine the liquid velocity, amount of vacuum and rate of sand flow.
If the spray nozzle is chosen to give the maximum pressure and flow rate
possible for the pump, the rate of sand flow will also be at maximum. Total
vacuum seal and maximum swirl velocity are obtained at 5º spray nozzle.
- Because of
the water ingredient, it will not create any environmental pollution
problem caused by fluttering the micro power.
- It can
remove the burrs (surface projections) & scales formed on surface and
clean the surface without damaging the work piece.
surface finishing can access a homogeneous matte finish (spot pattern). It
can contribute significantly to the finishing demand for surface
- It only
applies small shot blasting effect to the surface to be finished and
improve and reinforce the material of work piece.
foreign materials after being removed will be rinsed and flushed out by
the jet of water.
- It doesn’t
require any chemical during operation.
- It doesn’t
affect the dimensions of the object.
