Mfundo yogwirira ntchito ya reverse circulation pobowola rig

Reverse circulation kubowola cholumikizirandi choboola chozungulira. Ndi oyenera kumanga mapangidwe osiyanasiyana ovuta monga quicksand, silt, dongo, mwala, miyala wosanjikiza, weathered thanthwe, etc., ndipo chimagwiritsidwa ntchito pomanga nyumba, milatho, kusungira madzi, zitsime, mphamvu, telecommunications, mvula ya engineering ndi ntchito zina.

Ntchito mfundo yareverse circulation kubowola:

Chomwe chimatchedwa reverse circulation pobowola cholumikizira chimatanthawuza kuti pogwira ntchito, chimbale chozungulira chimayendetsa chobowola kuti chidulidwe ndikuswa thanthwe ndi dothi mu dzenje, madzi otsekemera amalowa pansi pa dzenje kuchokera pampata wa annular pakati pa chitoliro chobowola. ndi dzenje khoma, kuziziritsa pobowola pang'ono, kunyamula thanthwe ndi dothi pobowola slag kuti wadulidwa, ndi kubwerera pansi kuchokera kubowola chitoliro pabowo. Panthawi imodzimodziyo, madzi otsekemera amabwerera ku dzenje kuti apange kuzungulira. Popeza m'mimba mwake mkati mwa chitoliro chobowola ndi chocheperako kuposa cha chitsime, madzi amatope omwe ali m'bowolo amakwera mwachangu kuposa momwe amayendera. Si madzi oyera okha, komanso amatha kubweretsa slag yobowola pamwamba pa chitoliro chobowola ndikuyenderera ku thanki yamatope, komwe matope amatha kubwezeretsedwanso pambuyo poyeretsedwa.

Mfundo yake ndikuyika chitoliro chobowola mu dzenje lodzaza ndi madzi otuluka, ndipo ndi kuzungulira kwa tebulo lozungulira, yendetsani ndodo yobowola mumlengalenga ndikuzungulira ndikudula mwala ndi dothi. Mpweya woponderezedwa umapopedwa kuchokera ku mphuno kumapeto kwa chitoliro chobowola, kupanga chisakanizo cha matope, mchenga, madzi ndi mpweya wopepuka kuposa madzi a mu chitoliro chobowola ndi dothi ndi mchenga zikudulidwa. Chifukwa cha kuphatikizika kwa kusiyana kwapakati ndi kunja kwa chitoliro chobowola mkati ndi kunja kwa chitoliro chobowola ndi kuthamanga kwa mpweya, chisakanizo cha madzi amchenga amatope amawuka pamodzi ndi madzi akuthamanga, ndipo adzatulutsidwa mu dziwe lamatope kapena posungira madzi. thanki kudzera pa hose ya pressure. Dothi, mchenga, miyala ndi zinyalala za miyala zidzakhazikika mu dziwe lamatope, ndipo madzi osefukira adzayendereranso mu dzenjelo.

Makhalidwe areverse kuzungulira pobowola cholumikizira:

1. Kubowola kozungulira kumakhala ndi mkono wamakina wokhala ndi chitoliro chobowola, chomwe chitha kugwiritsidwa ntchito pamabowo owongoka komanso mawonekedwe ang'onoang'ono a vertex. Panthawi imodzimodziyo, chobowolacho chimakhalanso ndi chowongolera chothandizira cha hydraulic, chomwe chimachepetsa kwambiri mphamvu ya ogwira ntchito pamakina, ndipo chimathandizira kumanga makina otetezeka komanso otukuka.

2. Chombo chobowola chimagwiritsa ntchito makina oyendetsa makina oyendetsa magetsi ndi ma hydraulic walk chassis, omwe ndi osavuta kusuntha komanso oyenerera ku zigwa, mapiri, mapiri ndi malo ena. Chassis ili ndi zopangira 4, kotero chobowoleracho chimakhala ndi kugwedezeka kochepa komanso kukhazikika bwino pakumanga pobowola.

3. Njira yobowola yozungulira yozungulira imayendetsedwa ndi mphamvu yamagetsi, yokhala ndi phokoso lochepa komanso kuipitsidwa, kuchita bwino kwambiri komanso mphamvu yayikulu yosungira mphamvu.

4. Njira yobowola yozungulira yozungulira imakhala yogwira ntchito zambiri, ndipo zigawo zonse zofunika ndizotsika mtengo. Dongosololi lili ndi chitetezo champhamvu komanso zida zamagetsi.

5. Zogwirizira ndi zida za ma actuators onse a reverse circulation pobowola rig zili pa nsanja yogwirira ntchito, yomwe ili yabwino komanso yodalirika kuti igwire ntchito ndi kuwongolera.

6. Reverse circulation pobowola cholumikizira utenga wapadera pobowola chimango. Njira yobowola ndi yayikulu, kukana kwa torsion ndikwambiri, kapangidwe kake ndi kosavuta, kukonza ndikwabwino, kusamutsidwa ndikosavuta, ntchito ya orifice ndiyosavuta, ndipo kubowola kwakukulu kwa vertex kumatha kupangidwa.

7. Kubowola kozungulira kozungulira kumatenga mutu waukulu wamagetsi ndi ntchito yokana kukhudzidwa kwakukulu. Liwiro lozungulira ndiloyenera kutengera mayendedwe a mpweya. Mphamvu yokweza, makokedwe ndi magawo ena amatha kukwaniritsa zofunikira za 100M osaya mpweya wozungulira pobowola DTH ndi zofunikira zina.
