Another part is rotated counterclockwise high pressure runner 22 by the effluent groove 24 of screen casing 7, the impact hammer of loop start device 6 or impact hammer rotates clockwise high pressure runner 23, the impact hammer of impact hammer 5 rotates clockwise sump pit 18 or impact hammer rotates counterclockwise sump pit 19, after entering to impact tup groove 34, rotated clockwise sump pit 18 by impact hammer or impact hammer rotates counterclockwise the notch of sump pit 19 and discharges, then flowed to drill bit by the drain hole 25 of screen casing 7.
A part is by the liquid flow side opening 32 of orifice plug 8 again, the liquid flow mouth 31 of positioning sleeve 10, diaphragm seal through hole 39 enters to the loop start device of assembling set 4 and rotates clockwise guiding gutter 28 and loop start device rotates counterclockwise guiding gutter 40, then rotate clockwise guiding gutter 28 by loop start device and loop start device rotates counterclockwise the pod apertures 27 being respectively provided with on guiding gutter 40, the loop start device of impact hammer 5 rotates counterclockwise sump pit 20 or after loop start device rotates clockwise the startup tup groove 16 that sump pit 21 enters loop start device 6, sump pit 20 is rotated counterclockwise or loop start device rotates clockwise notch and the dredging flow groove 26 of sump pit 21 through loop start device, drill bit is flowed to by drain hole 25.
Detailed process is: when impact hammer 5 starting of oscillation counterclockwise, as shown in figure 14, highly pressurised liquid is by rotating counterclockwise high pressure runner 22 and impact hammer rotates clockwise sump pit 18 and arrives impact tup groove 34(and impact chamber through impact hammer after the effluent groove 24 of screen casing 7) side；Under the effect of highly pressurised liquid, impact hammer 5 starts to rotate counterclockwise, it is gradually filled with liquid in the impact tup groove 34 of this side, its volume is made to become big, impact tup groove 34 opposite side volume is gradually reduced by compression, and the liquid in impact tup groove 34 opposite side rotates counterclockwise sump pit 19 through impact hammer and rotated counterclockwise the notch outflow of groove 19 by impact hammer, eight drain holes 25 finally by screen casing 7 lower end flow to drill bit.
When impacting tup 30 and rotating counterclockwise in impacting tup groove 34, 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 is rotated counterclockwise guiding gutter 40 by loop start device and rotates clockwise sump pit 21 through loop start device and enter startup tup groove 16, thus accelerates the rotation of loop start device 6.Loop start device 6 rotary course starts tup groove 16 1 Side Volume be gradually increased, start tup groove 16 opposite side volume gradually to be reduced by compression, and the liquid in startup tup groove 16 opposite side rotates counterclockwise sump pit 20 through loop start device and 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 starting of oscillation state clockwise.Highly pressurised liquid is by rotating clockwise high pressure runner 23 and impact hammer rotates counterclockwise sump pit 19 and arrives impact tup groove 34 through impact hammer after the effluent groove 24 of screen casing 7, under the effect of highly pressurised liquid, impact hammer 5 starts to turn clockwise, as shown in figure 15, impact tup groove 34 side is gradually filled with liquid, its volume is made to become big, impact tup groove 34 opposite side volume is gradually reduced by compression, and the liquid in impact tup groove 34 opposite side rotates clockwise sump pit 18 through impact hammer and is rotated clockwise the notch outflow of groove 18 by impact hammer, eight drain holes 25 finally by screen casing 7 lower end flow to drill bit.When impacting tup 30 and rotating clockwise in impacting tup groove 34, 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 is rotated clockwise guiding gutter 28 by loop start device and rotates counterclockwise sump pit 20 through loop start device and enter and start tup groove 16 and accelerate the rotation of loop start device 6.Loop start device 6 rotary course starts tup groove 16 side spatial volume be gradually increased, start tup groove 16 opposite side spatial volume gradually to be reduced by compression, and the liquid in startup tup groove 16 opposite side rotates clockwise sump pit 21 through loop start device and 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 circumference torsional impact generator that surges, and it will repeat aforesaid operations, and constantly circulate, and be consequently formed frequency low-amplitude Ground shock waves.The impact that this circumference torsional impact generator that surges produces will be directly transferred to drill bit by housing 3, and then realize providing the purpose of frequency low-amplitude torsional pulse to drill bit.
