A part is by the liquid stream side opening 32 of orifice plug 8 again, the liquid head piece 31 of positioning sleeve 10, the loop start device that diaphragm seal through hole 39 enters to assembly set 4 rotates clockwise guiding gutter 28 and loop start device rotates counterclockwise guiding gutter 40, then guiding gutter 28 is rotated clockwise by loop start device and loop start device rotates counterclockwise the pod apertures 27 that guiding gutter 40 is arranged respectively, the loop start device of impact hammer 5 rotates counterclockwise sump pit 20 or loop start device and rotates clockwise after sump pit 21 enters the startup tup groove 16 of loop start device 6, notch and the dredging flow groove 26 that sump pit 20 or loop start device rotate clockwise sump pit 21 is rotated counterclockwise through loop start device, drill bit is flowed to by drain hole 25.
Detailed process is: when the counterclockwise starting of oscillation of impact hammer 5, as shown in figure 14, highly pressurised liquid by after the effluent groove 24 of screen casing 7 through impact hammer rotate counterclockwise high pressure runner 22 and impact hammer rotate clockwise sump pit 18 arrive impact tup groove 34(and impact chamber) side; Under the effect of highly pressurised liquid, impact hammer 5 starts to be rotated counterclockwise, liquid is full of gradually in the impact tup groove 34 of this side, its volume is made to become large, impact tup groove 34 opposite side volume to be reduced by compression gradually, and impact liquid in tup groove 34 opposite side and rotate counterclockwise through impact hammer the notch that sump pit 19 rotates counterclockwise groove 19 by impact hammer and flow out, eight drain holes 25 finally by screen casing 7 lower end flow to drill bit.
When impact tup 30 impact rotate counterclockwise in tup groove 34 time, loop start device 6 rotates counterclockwise with impact hammer 5, and when impact hammer 5 stops operating, loop start device 6 rotates counterclockwise continuing due to effect of inertia.Loop start device 6 rotates counterclockwise simultaneously, and high-pressure fluid rotates counterclockwise guiding gutter 40 by loop start device and rotates clockwise sump pit 21 through loop start device and enter and start tup groove 16, thus accelerates the rotation of loop start device 6.Start tup groove 16 1 Side Volume in loop start device 6 rotary course to increase gradually, start tup groove 16 opposite side volume to be reduced by compression gradually, and the liquid started in tup groove 16 opposite side rotates counterclockwise sump pit 20 through loop start device is flowed out by dredging flow groove 26, eight drain holes 25 finally by screen casing 7 lower end flow to drill bit.
At the end of loop start device 6 rotates counterclockwise, impact hammer 5 just reaches clockwise starting of oscillation state.Highly pressurised liquid rotates counterclockwise sump pit 19 and arrives by rotating clockwise high pressure runner 23 and impact hammer through impact hammer after the effluent groove 24 of screen casing 7 and impact tup groove 34, under the effect of highly pressurised liquid, impact hammer 5 starts to turn clockwise, as shown in figure 15, impact tup groove 34 side and be full of liquid gradually, its volume is made to become large, impact tup groove 34 opposite side volume to be reduced by compression gradually, and impact liquid in tup groove 34 opposite side and rotate clockwise through impact hammer the notch that sump pit 18 rotates clockwise groove 18 by impact hammer and flow out, eight drain holes 25 finally by screen casing 7 lower end flow to drill bit.When impact tup 30 impact rotate clockwise in tup groove 34 time, loop start device 6 rotates clockwise with impact hammer 5, and when impact hammer 5 stops operating, loop start device 6 rotates clockwise continuing due to effect of inertia.
While loop start device 6 rotates clockwise, high-pressure fluid rotates clockwise guiding gutter 28 by loop start device and rotates counterclockwise sump pit 20 through loop start device and enter and start the rotation that tup groove 16 accelerates loop start device 6.Start tup groove 16 side spatial volume in loop start device 6 rotary course to increase gradually, start tup groove 16 opposite side spatial volume to be reduced by compression gradually, and the liquid started in tup groove 16 opposite side rotates clockwise sump pit 21 through loop start device is flowed out by dredging flow groove 26, eight drain holes 40 finally by screen casing 7 lower end flow to drill bit.
Aforesaid operations process is a complete working period of this circumferential torsional impact generator that surges, and it will repeat aforesaid operations, constantly circulate, and forms frequency low-amplitude Ground shock waves thus.The impact that this circumferential torsional impact generator that surges produces directly will reach drill bit by housing 3, and then realize the object providing frequency low-amplitude torsional pulse to drill bit.
