S3: centrifugal pump (13) are started by external power supply, promote centrifugal pump (13) that the water in water storage box (12) is passed through low pressure water
Pipe (14) is injected into chamber (6) inner cavity, is led to be injected into behind the bottom of the water submerged spray nozzle device (8) in chamber (6)
External power supply starting high-pressure plunger pump (15) is crossed, promotes high-pressure plunger pump (15) that the water in water storage box (12) is passed through high-pressure water pipe
(16) it is injected into spray nozzle device (8), and centrifugal pump (13) is promoted to continue working, be always maintained at the bottom of spray nozzle device (8)
It is submerged in the water of chamber (6) inner cavity, after reaching certain altitude (bottom that water surface elevation is no more than workpiece (4)), water meeting
It is flowed into recycling bins (5) by return pipe (17)；
S4: the water in chamber (6) can be flowed into holding holes (82) by spilling water channel (86), and outer with workpiece (4)
Wall contact, is injected into the water on spray nozzle device (8) in high pressure runner (83), since pressure is bigger, and contracted channel (84)
Diameter be less than high pressure runner (83), the water in high pressure runner (83) can enter holding holes (82) along contracted channel (84)
In, thus low pressure water flow interaction in high pressure water flow and spilling water channel (86) in contracted channel (84) and generate cavitation sky
Bubble, cavitation bubble crumble and fall on the surface of workpiece (4) and generate microjet and shock wave, keep the surface of workpiece (4) brilliant
Body structure changes and generates biggish residual stress, to complete the reinforcing to workpiece (4) surface；
S5: starting motor (9) by external power supply, and motor (9) is promoted to drive lead screw (10) rotation, and lead screw (10) can drive spiral shell
Line cylinder (11) is moved left and right along lead screw (10), so as to drive spray nozzle device (8) to move left and right, so as to workpiece
(4) table wall is strengthened, and guarantees the uniformity strengthened, and adjusts workpiece (4) after workpiece (4) right side is strengthened
Head re-starts table wall intensive treatment.
