Description
Technical field:
The utility model relates generally to the fluidics field, is applied to surface treatment and crushing mechanism, specifically is a kind of rotation abradant jet device.
Background technology:
Ship Building and Repairing, railway freight-car such as build at industrial field, all be unable to do without process of surface treatment such as large-area steel plate surface de-scaling, paint removal.Traditional dry blasting or ball blast technology are eliminated gradually owing to form dust pollution easily, and outdoor work is clearly forbidden especially.
The high-pressure water jet process for treating surface has solved dust pollution question, and its technology replaces traditional sandblast and ball blast technology gradually.
The advantage of high pressure pure water jet stream rust cleaning is that technology is succinct, realize automated job easily, shortcoming is that required pressure is all more than 200MPa, to the requirement height of equipment, thereby the equipment use cost is also very high, and high pressure pure water jet work unit area rust cleaning energy consumption is also high 3～5 times than technologies such as sandblasts simultaneously.
Abrasive material (or slurry) water jet is promptly sneaked into abrasive material in water jet, both solved dust pollution question, and energy consumption is also suitable with traditional blasting craft, thereby this technology has obtained extensive popularization.
But mix to produce because abrasive material (or slurry) water jet is two plumes, promptly water under high pressure sprays from (operating) water nozzle, forms negative pressure suction abrasive material (or slurry) at abrasive material shower nozzle hybrid chamber, and forms abradant jet with being sprayed by abrasive jet after water jet mixes again.And the runner of abrasive material (or slurry) must be smooth, otherwise will stop up.Therefore, the abrasive material shower nozzle just can not through a swivel joint, just can produce rotating fluid as the pure water fluid jet nozzle.Just because of this, existing abradant jet operation all is that armrest is held the shower nozzle mobile operating or added to move by mechanical reciprocally swinging and realizes the large-area planar operation.Swing with shower nozzle owing to connect the high-pressure water hose and the feeding abrasive material pipe of shower nozzle, it is big to add the vibrations that oscillating motion causes, so the reciprocally swinging frequency is unsuitable too high, thereby has restricted the speed of abradant jet operation, has restricted giving full play to of jet effect.And just can only rotate by workpiece for inner-walls of duct rust cleaning operation, if fixed-piping, then can't operation.
