I-Mining Drill Rig Rotary Head Housing

I-Mining Drill Rig Rotary Head Housing iyindawo ebiyelwe emaphakathi equkethe amagiya okushayela okujikelezayo, ama-bearing, kanye nesixhumi esibonakalayo se-hydraulic motor yezinsimbi zokubhola ezingaphezulu nezingaphansi komhlaba. Ingaphansi kwemithwalo ye-torque eyeqisayo (efika ku-25,000 N·m), ukudlidliza okujikelezayo, nezimo zezimayini ezilimazayo, le ndlu idinga izakhiwo zemishini ezihlukile nokunemba kobukhulu. I-Ningbo Ruican's QT700-2 ductile iron investment casting iletha amandla aqinile (700 MPa), ukumelana nokugqokwa, kanye nejometri yangaphakathi eyinkimbinkimbi edingwa yimishini yezimayini ama-OEM - konke kusekelwa izinhlelo zekhwalithi ze-IATF 16949.

Ukucaciswa Kwempahla

Inqubo Yokukhiqiza

1. Umjovo Wephethini ye-Wax : Umjovo we-wax onefomethi enkulu yejometri yezindlu efika kububanzi obungu-500mm
2. I-Shell Building : igobolondo le-ceramic elingu-8–10 eline-silica ehlanganisiwe kanye ne-mullite ukuze liqine ukusakaza okukhulu
3. I-Dewaxing nokudubula : I-autoclave dewaxing elawulwayo (isilinganiso serempu <2°C/min), igobolondo lidubula ku-1050°C
4. Ukuthela : I-QT700-2 i-ductile iron ethelwe ku-1400-1450°C ngokwelashwa kwe-nodularization (magnesium FeSi)
5. I-Knockout & Cleaning : Ukususwa kwegobolondo, ukususwa kwesango nesikhuphukeli, ukuhlanzwa kwe-abrasive
6. Ukwejwayelekile : 900°C amahora ama-2, umoya upholile ukuze kuzuzwe isakhiwo se-pearlitic matrix
7. I-CNC Machining : I-4-axis CNC yokuthwala (i-H7 tolerance, Ø180–350mm), imbobo yegiya, nobuso be-flange
8. Ukuhlolwa Kwengcindezi : Amabha ama-5 wokuhlolwa kwe-hydraulic yobuqotho bezindlu (ukubamba imizuzu engama-30)
9. Ukuhlola : I-CMM, ukuhlolwa kwe-ultrasonic (ASTM E2375), inhlayiya kazibuthe, imephu yokuqina

Izici Eziyinhloko

• Amandla eTorque Ephakeme : QT700-2's 700 MPa amandla okubamba kanye nokuqina okungu-225–305 HB ukumelana nemithwalo ejikelezayo efinyelela ku-25,000 N·m
• Ukusakaza Kwefomethi Enkulu : Ikhono lokutshala imali elifika ku-65 kg, likhiqiza izimbotshana eziyinkimbinkimbi zangaphakathi ngaphandle kwama-cores
• I-Precision Bearing Bores : Izihlalo ezithwele ezinomshini we-CNC ukuya ku-H7 tolerance (±0.02mm ye-Ø300mm bore), iqinisekisa ukuqondanisa kwe-gear mesh
• I-Vibration Damping : Umthamo we-Ductile iron damping ngokwemvelo (i-3x engcono kunensimbi) wehlisa umsindo wegiya futhi welula ukuphila
• Ivivinywe Ingcindezi : Ukuhlolwa kwengcindezi ye-hydraulic engu-100% kubha engu-5 kuqinisekisa ukusebenza okuqinile kukawoyela ezindaweni ezigcotshisiwe
• I-Ultrasonic Verified : Ukuhlolwa kwe-ASTM E2375 kuqinisekisa ukuzwakala kwangaphakathi kwezinhlelo zokusebenza zezimayini ezibaluleke kakhulu zokuphepha

Izinkambu Zohlelo

• Izinsimbi zokumba i-rotary blasthole yezimayini ezingaphezulu
• Imishini yokumba ijumbo engaphansi komhlaba
• Amarigi okumba okuhlola (i-diamond core drilling)
• Isisekelo sokumba izinto (i-piling)
• Imishini yokumba imithombo yamanzi
• Imishini yokumba i-Horizontal directional (HDD).

Kungani Khetha i-Ningbo Ruican

Iminyaka engu-17+ ka-Ningbo Ruican yeminyaka engu-17+ yokufaka utshalomali kwensimbi yefomethi enkulu, kuhlanganiswe nesitifiketi se-IATF 16949, kusibeka njengozakwethu othembekile kubakhiqizi bemishini yezimayini emhlabeni wonke. Izindlu zethu ezijikelezayo ze-QT700-2 zifakazelwe emkhakheni wezinhlelo ze-OEM zezimayini ze-Tier 1 kulo lonke elase-Australia, eChile, naseNingizimu Afrika. Sihlinzeka ngesitifiketi esiphelele sezinto ezibonakalayo, imibiko ye-NDT, izifundo zamakhono (Cpk ≥ 1.33), nosekelo lwe-DFM oluphelele — okuhlanganisa iphethini ye-wax ephrintiwe ye-3D yokuphindaphinda idizayini esheshayo.
