Sandblasting machine is a concrete application of fluidics, is used for the cleaning of boats and ships, pipeline, workpiece and equipment, scale removal
Etc. aspect, typically have the sandblasting machines such as gas-solid two-phase, liquid-solid two phase and gas-liquid-solid three-phase.The thinnest abrasive material is mixed in pressure-air
Granule, makes abrasive particle and pressure-air spray through shower nozzle after being sufficiently mixed again, thus forms the mill with flank speed
Material particle flux, here it is gas-solid two-phase abradant jet technology.Different according to feed mode, gas-solid two-phase abradant jet is mixed after being divided into
Closing abradant jet and the Premixed Abrasive Water Jet two kinds, rear hybrid current application is less；Front mixing refers in advance at sandblasting machine
By abrasive material and mixed gases in abrasive can, then air and the acceleration of abrasive suspension mixture are delivered to spray gun and carried out operation, have
Jet pressure is relatively low, consuming little energy, the advantages such as kinetic energy is big that abrasive material obtains.
And current sandblasting machine typically has single cylinder and twin-tub two kinds, the abrasive concentration in single cylinder sandblasting machine cylinder is relatively low, the closeest

Identical.6th phase " shipbuilding technology " in 2008 " control of conventional shot-peening (sand) machine and performance thereof " describes the most more advanced company
Ideotype twin-tub sandblasting machine, sandblasting machine cylinder divides upper and lower two storehouses, charge door and upper and lower two storehouses to regulate air pressure by plugging valve, it is achieved
Continuous charging and sandblasting, but when storehouse hole capital after selling all securities is without abrasive material instantly, during lower storehouse batch (-type) is concentrated charging by upper storehouse, fall highly concentrated
Degree abrasive material is shorter with the immixture time of pressure-air, the not i.e. sky of the even concentration of air and abrasive mixture in lower storehouse
Gas and abrasive suspension uniformity of mixture are poor, so that the air of spray gun spray nozzle ejection and abrasive mixture seriality and uniformity
Not good enough, easily block spray gun spray nozzle, have impact on sandblasting quality and effect.
