Kaishan KG420TH Surface DTH Drilling Rig — Kusonkhanitsa Fumbi Kogwira Ntchito Moyenera Kwambiri Kuti Liziyeretsedwa

Kaishan KG420TH ndi makina obowola a DTH opangidwa ndi dizilo, omwe amagwira ntchito bwino kwambiri, omwe amapangidwa kuti azigwiritsa ntchito anthu omwe amaika patsogolo kutsata malamulo okhudza chilengedwe popanda kuwononga mphamvu zobowola. Kutengera ndi nsanja yodziwika bwino ya KG420T, dzina la "H" limasonyeza kuphatikiza kwa njira yosonkhanitsira fumbi lolemera. Monga wogulitsa wovomerezeka wa Kaishan Group, Shaanxi Kaishan akubweretserani makina othandizidwa ndi zaka pafupifupi makumi asanu ndi awiri za cholowa cha mafakitale komanso uinjiniya wapamwamba padziko lonse lapansi.

Chosiyanitsa chachikulu cha KG420TH ndi chosonkhanitsa fumbi cha QZA-120 chokhazikika, chokhala ndi fyuluta 12 zomwe zimagwira bwino tinthu tating'onoting'ono panthawi yobowola. Pamalo omwe amafunika kusefedwa kwambiri kapena pamene mabowo akubowola mabowo opitilira 130mm, chosonkhanitsa cha QZA-140 chosankha chokhala ndi mafyuluta 16 chikupezeka. Dongosololi silimangotsimikizira malo abwino kwa ogwira ntchito komanso limateteza zigawo zamkati za rig ku fumbi losalimba, zomwe zimapangitsa kuti injini ndi makina a hydraulic zikhale ndi moyo wautali.

Pofuna kuwerengera mphamvu zowonjezera zomwe zimafunika pa makina osonkhanitsira fumbi, KG420TH ili ndi injini ya Yuchai YC4DK100-T304 yokonzedwanso. Injiniyi imapereka mphamvu ya 73.5KW pa 2200rpm, ndipo imapereka malo ofunikira kuti igwire ntchito ndi ma hydraulic amphamvu komanso fumbi vacuum nthawi imodzi, kuonetsetsa kuti kuchuluka kwa mphamvu zomwe zimalowa kumakhalabe kofanana ngakhale pamwala wolimba kwambiri (f=6-20).

Kapangidwe kake, chogwirirachi chili ndi nyumba yokhuthala komanso njira yolumikizira yolimba. Kuphatikiza kwa injini yoyenda ya plunger yokhala ndi mphamvu zambiri komanso makina oyendetsera mawilo anayi kumalola makina a 5350KG kuyenda m'malo ovuta ndikukwera mpaka madigiri 30. Dongosolo lolinganiza njanji (±10°) limaonetsetsa kuti chogwirirachi chikhale chokhazikika kapena chopingasa pansi pa miyala yosagwirizana, zomwe ndizofunikira kwambiri kuti mabowo akhale olondola.

Mphamvu yobowola ikadali yapamwamba kwambiri, yokhala ndi mphamvu yozungulira ya 3500N·m ndi 3175mm feed stroke yoyendetsedwa ndi silinda yamafuta yolemera komanso makina ozungulira. Chogwirirachi chimagwira mabowo a Φ90-152mm mosavuta, zomwe zimapangitsa kuti chikhale chida chogwiritsidwa ntchito kwambiri pobowola benchi mu migodi ndi maziko omangira. Magawo osinthira beam ndi boom amalola kusinthasintha kwakukulu, kuphatikizapo kubowola mopingasa pamalo okwera mpaka 350mm.

Shaanxi Kaishan akulangiza kuti KG420TH igwirizane ndi ma compressor athu onyamula a KSCY kapena LGCY series kuti zitsimikizire kuti mpweya wa 13-20m³/min ukupezeka nthawi zonse. Kuphatikiza kumeneku kumapereka mphamvu ya "kutsuka ndi kuphwanya" yofunikira pakugwira ntchito bwino kwa DTH. Ndi kafukufuku wapadziko lonse wa Kaishan, kuphatikiza malo athu aukadaulo ku Seattle, KG420TH ikuyimira ukadaulo wapamwamba kwambiri wamakono komanso wosawononga chilengedwe.
