1with the arc length X of groove
2between to meet certain relation.In order to make bar cylinder 47 obtain very large impact force, water should pass through liquid rectangular slits 125 with full flow velocity, should ensure that water flow through liquid rectangular slits 125 and has enough throughput time, the therefore arc length X of groove
2with blade 110 width X
1between ratio need be greater than 2 (i.e. X
2/ X
1> 2).The vibration frequency of hydraulic piston vibrator 4 is consistent with keying frequency Fig. 9 crossing liquid rectangular slits 125, this example is crossed liquid rectangular slits 125 and is opened and close once, the piston 41 realizing hydraulic piston vibrator 4 vibrates once, mandrel 13 rotates a circle, export 5 impact of water hammer ripples and promote piston 41 up-down vibration 5 times, in order to ensure the general X of the vibration frequency of piston 41
2/ X
1value be advisable between 3-8, needed for actual conditions, frequency selects this value, the higher X of frequency
2/ X
1ratio value less.
When rotary electric machine 14 adopts asynchronous motor, by the speed governing of variable ratio frequency changer device, the frequency of the rotation of mandrel 13 thus the vibration of change piston 41 can be changed, realize frequency modulation.When rotary electric machine 14 adopts synchronous motor or servomotor to drive, but the vibration frequency of mandrel 13 stable output, realize frequency stabilization.
