Chipangizo chobowolera chozungulirandi makina obowola ozungulira. Ndi oyenera kumanga zinthu zosiyanasiyana zovuta monga mchenga wofulumira, matope, dongo, miyala yamwala, miyala yosweka, ndi zina zotero, ndipo amagwiritsidwa ntchito kwambiri pomanga nyumba, milatho, kusamalira madzi, zitsime, magetsi, kulumikizana, kugwetsa mvula ndi mapulojekiti ena.
Mfundo yogwirira ntchito yachida chobowolera chozungulira:
Chomwe chimatchedwa reverse circulation drilling rig chimatanthauza kuti pogwira ntchito, rotary disc idzayendetsa drill bit kuti idule ndikuswa thanthwe ndi dothi lomwe lili m'dzenje, madzi otuluka adzayenda pansi pa dzenje kuchokera pamalo ozungulira pakati pa drill payipi ndi khoma la dzenje, kuziziritsa drill bit, kunyamula miyala ndi dothi lodulidwa, ndikubwerera pansi kuchokera ku drill payipi. Nthawi yomweyo, madzi otuluka adzabwerera ku dzenje kuti apange cycle. Popeza kukula kwa drill payipi ndi kochepa kwambiri kuposa kwa wellboore, madzi a matope omwe ali mu drill payipi amakwera mofulumira kwambiri kuposa momwe amayendera nthawi zonse. Sikuti ndi madzi oyera okha, komanso amatha kubweretsa drill slag pamwamba pa drill payipi ndikuyenderera ku thanki ya matope, komwe matope amatha kubwezeretsedwanso pambuyo poyeretsedwa.
Mfundo yaikulu ndi kuyika chitoliro chobowolera m'dzenje lodzaza ndi madzi osambira, ndipo pozungulira tebulo lozungulira, yendetsani ndodo yolumikizira mpweya yolimba ndi chobowolera kuti muzungulire ndikudula thanthwe ndi dothi. Mpweya wopanikizika umapopedwa kuchokera ku nozzle kumapeto kwa chitoliro chobowolera, ndikupanga chisakanizo cha matope, mchenga, madzi ndi gasi chopepuka kuposa madzi mu chitoliro chobowolera pomwe dothi ndi mchenga zikudulidwa. Chifukwa cha kusiyana kwa kuthamanga pakati pa mkati ndi kunja kwa chitoliro chobowolera ndi mphamvu ya mpweya, mpweya wosakaniza wa madzi a mchenga wa matope udzakwera pamodzi ndi madzi osambira, ndipo udzatulutsidwa mu dziwe la matope la pansi kapena thanki yosungira madzi kudzera mu payipi yopondereza. Dothi, mchenga, miyala ndi miyala zidzakhazikika mu dziwe la matope, ndipo madzi osambira adzayendanso mu dzenje lamadzi.
Makhalidwe achida chobowolera chozungulira:
1. Chobowolera chozungulira kumbuyo chili ndi mkono wamakina wokhala ndi chitoliro chobowolera, chomwe chingagwiritsidwe ntchito m'mabowo owongoka komanso m'malo ang'onoang'ono a vertex. Nthawi yomweyo, chobowoleracho chilinso ndi winch yothandizira ya hydraulic, yomwe imachepetsa kwambiri mphamvu ya ogwira ntchito pamakina, ndipo imathandiza kuti makinawo akhale otetezeka komanso otukuka.
2. Chipangizo chobowolera chimagwiritsa ntchito chobowolera chaukadaulo ndi choyezera kuyenda cha hydraulic, chomwe ndi chosavuta kusuntha ndipo chimagwiritsidwa ntchito bwino m'malo otsetsereka, m'mapiri, m'mapiri ndi m'malo ena. Chipangizocho chili ndi zotchingira zinayi, kotero chipangizocho chimakhala ndi kugwedezeka kochepa komanso kukhazikika bwino panthawi yomanga.
3. Chipangizo chobowolera chozungulira chimayendetsedwa ndi mphamvu yamagetsi, yokhala ndi phokoso lochepa komanso kuipitsidwa pang'ono, magwiridwe antchito apamwamba komanso mphamvu yayikulu yosungira mphamvu.
4. Chipangizo chobowolera chozungulira chimagwira ntchito zambiri, ndipo zigawo zonse zofunika ndi zinthu zotsika mtengo. Dongosololi lili ndi zoteteza kuthamanga kwa mpweya komanso zida zochenjeza.
5. Zogwirira ndi zida za oyambitsa onse a reverse circulation rig zili pa nsanja yogwirira ntchito, yomwe ndi yabwino komanso yodalirika yogwiritsira ntchito ndi kuwongolera.
6. Chobowolera chozungulira chimagwiritsa ntchito chimango chapadera chobowolera. Njira yobowolera ndi yayikulu, kukana kwa torsion ndi kwakukulu, kapangidwe kake ndi kosavuta, kukonza ndikosavuta, kusamutsa malo ndi kosavuta, ntchito ya orifice ndi yosavuta, ndipo kubowola ngodya yayikulu ya vertex kungapangidwe.
7. Chobowolera chozungulira chozungulira chimagwiritsa ntchito mutu waukulu wamagetsi womwe umagwira ntchito yolimbana ndi kugunda kwakukulu. Liwiro lozungulira ndiloyenera zosowa za mlengalenga wozungulira. Mphamvu yokweza, torque ndi magawo ena amatha kukwaniritsa zofunikira za 100M shallow air reverse circulation DTH circulation ndi zofunikira zina za ndondomeko.
