Kaishan KG420B Surface DTH Drilling Rig — Kukhazikika Kwambiri ndi Kuchita Bwino Kwambiri

Kaishan KG420B ndi chida chobowolera cha DTH chogwira ntchito bwino kwambiri, chogawanika chomwe chimapangidwira ntchito zolemera za kukumba miyala ndi migodi. Chida ichi chili ndi njira yapadera yopindika komanso injini yamphamvu ya Yuchai 4-cylinder, ndipo chimapangidwa kuti chikhale chokhazikika kwambiri pamalo otsetsereka komanso pamalo osalinganika. Ndi chisankho chabwino kwambiri kwa ogwiritsa ntchito omwe amafunikira makina odalirika komanso amphamvu omwe amatha kubowola mabowo akuluakulu m'malo ovuta.

Mtundu uwu ndi wosintha kwambiri mu mndandanda wa KG420, makamaka wokonzedwa kuti ugwirizane ndi miyezo yotulutsa dizilo pomwe ukuwonjezera mphamvu yonse ya makina. Injini ya Yuchai YC4DK80-T302 imapereka 58KW yolimba, yomwe imapereka maziko a torque yozungulira komanso liwiro la chidacho. Shaanxi Kaishan wapanga chida ichi kuti chigwire mainchesi a mabowo kuyambira 90mm mpaka 130mm, zomwe zimapangitsa kuti chikhale chimodzi mwa zida zogwiritsidwa ntchito kwambiri m'gulu lake.

Chinthu chodziwika bwino cha makina a KG420B ndi njira yopindika yokhala ndi chimango cholumikizidwa ndi kulinganiza kwa njira (±10°). Izi zimathandiza kuti chogwiriracho chikhale ndi mphamvu yokoka yochepa komanso kukoka bwino ngakhale chikukwera madigiri 30. Kugwiritsa ntchito injini yoyendera ya plunger kumatsimikizira kuyendetsa bwino kwa torque, pomwe makina oyendetsa mawilo anayi amapereka kugwira kofunikira pansi pa miyala yolimba. Nyumba yolimba yokhala ndi mawonekedwe okhuthala ndi mphete zonyamulira zophatikizika zimawonjezera kulimba komanso kusunthika kwapamwamba kwa mafakitale.

Kuboola kwakhala bwino kwambiri pogwiritsa ntchito silinda yayikulu yonyamulira ndi unyolo wolimbikitsidwa wa masamba. Kusintha kumeneku kumatanthauza mphamvu yonyamulira ya 25KN komanso kuthamanga kwa 3780mm, kuonetsetsa kuti nyundo ikugwira ntchito bwino komanso kuyang'anira ndodo. Ndi mphamvu yozungulira ya 2000N·m komanso liwiro la 140rpm, KG420B imatha kuyendetsa bwino kudzera mu miyala yolimba (f=6-20) pogwiritsa ntchito nyundo za 3″ kapena 4″.

Dongosolo la boom ndi beam la chipangizochi limapereka kusinthasintha kwapadera. Ndi kupendekeka konse kwa beam kwa 185° ndi kusinthasintha kwa 145°, ogwiritsa ntchito amatha kufika pamalo ovuta kuboola mosavuta. Mbali yolipirira ya 900mm imatsimikizira kuti njanji yotsogolera imakhalabe yolumikizana ndi nthaka, kuchepetsa kugwedezeka ndikuwongolera kulondola kwa mabowo. Mabowo opingasa amatha kubooledwa pamtunda kuyambira 350mm mpaka 2750mm.

Kuti kuboola bwino, tikukulimbikitsani kugwirizanitsa KG420B ndi ma compressor a Kaishan okhala ndi mphamvu yothamanga kwambiri monga KSCY550-13, KSCY570/12-550/15, kapena LGCY17/18-18/15T. Chida ichi ndi choyenera kwambiri pa migodi yapakati mpaka yayikulu, kumanga misewu, ndi mapulojekiti osiyanasiyana ofunikira kuboola mozama komanso molondola.
