Yepamberi hydraulic system yakanyatso kugadzirirwa pombi suction reverse kutenderera. Iyo pombi huru, inotenderera musoro mota, vharafu huru, inoremedza yekubatsira vharafu uye zvimwe zvinhu zve hydraulic zvinogadzirwa neRexroth, Kawasaki yeKorea, hydraulic HC yeItari, Jiangsu Hengli, Sichuan Changjiang Hydraulic uye mamwe anozivikanwa mabhureki kumba nekune dzimwe nyika, nekuita kwepamusoro uye kwakagadzikana.
11. Zvose zvakakosha zvikamu (kuratidza uye mutongi) wemagetsi ekugadzirisa hurongwa hunotengeswa kunze kwenyika dzemarudzi emhando dzakakurumbira uye yepamusoro-yekupedzisira yepakutanga packaging; Bhokisi rekutonga rinotora yakavimbika yekudzika kwendege uye plug zvikamu; Gadzira yakasarudzika yemagetsi kudzora sisitimu yepamba pombi suction reverse kutenderera kudhirowa rig.
12. Switchboard yakaiswa kuseri kwema hydraulic pump stations uye yakafukidzwa nemavhavha pamwe chete nema hydraulic pump stations.
13. Sezvo pombi yevhu ichiiswa papuratifomu, kureba pakati pepombi yematope uye pamusoro pemvura yegomba remurwi inoderedzwa, kusimudza kusimudza kwepombi yematope kunopfupiswa, uye kushanda kwepombi yevhu kunovandudzwa zvikuru. .
14. Dhizaini yedhizaini pombi:￠325x25x2000 Iyo pombi yekuchera inotora tambo yekubatanidza, iri nyore kuisirwa otomatiki uye disassembly. Musoro webuckle uye nati pamigumo yese yepombi yekuchera ndeye taper rectangular buckle, yakagadzirwa ne35CrMo, Yakadzimwa uye yakapfava, uye pombi yekuchera inogadzirwa ne16Mn. Iyo welding process inotora preheating isati yatungirwa nekuchengetedza kupisa mushure mekupisa. Iyo welding mhando yepombi yekuchera inovimbiswa uye hupenyu hwesevhisi hunovandudzwa.
15. Zvishandiso zvekuchera: zvigadziro zvekuchera zvinoshandiswa mumudziyo uyu midziyo yekuchera inotenderera. Zvishandiso zvakasiyana zvekuchera zvinokurudzirwa kune vashandisi zvinoenderana neakasiyana geological mamiriro. Zvinoenderana nechimiro, kune maviri mapapiro, matatu bapiro uye mana mapapiro anotenderera ekuchera maturusi; Cylindrical rotary drilling tool. Kusarudzika nekuboora mazino: kune scraper type alloy kuchera mazino, roller drilling mazino uye anocheka mazino ekuchera.
- Maitiro ekuita
1. slurry pombi yakagadzirwa nenyanzvi dzekuchengetedza mvura kubva kuJiangsu University yetekinoroji ndiyo yakanyanya kufambira mberi muChina. Iyo impeller ine yakanyanya kushanda kushanda zvakanaka, uye kaviri chiteshi impeller inogamuchirwa, ine inoshamisa-yekuchengetedza simba mhedzisiro. Iyo pombi casing uye impeller inogadzirwa neyepamusoro chromium iron uye yekudyara kukanda maitiro, ine yakakwirira pamusoro pekupedzisira, yakanaka kupfeka kuramba uye hupenyu hurefu hwebasa. Iyo impeller inotora dynamic chiyero bvunzo, ine yakakwira chiyero uye nekukurumidza kumhanya. Chero bedzi iyo impeller currency yakasimba zvidimbu zvidiki pane yemukati dhayamita yepombi yekuboorera, kusanganisira matombo ematombo nematombo, inogona kuburitswa, iyo inodzivirira kudzokororwa kupwanywa kwezvimedu zvakasimba nehurungudo. High slag kubvisa kunyatsoshanda.
2. Torque yakakura uye simba rekusimudza, kunyanya yakakodzera kune yakaoma geology yakadai sematombo, hurungudo uye dombo;
3. manipulator uye winch yekubatsira inorongwa pane gantry furemu, iyo iri nyore, yakavimbika uye yebasa-yekuchengetedza kubvisa uye kuisa pombi dzekuchera;
4. Rotary musoro: nguva dzose simba rinobuda, automatic transmission. Pasi pemamiriro akasiyana e geological, iyo inochinjika mota yemusoro inotenderera inogadzirisa otomatiki torque yekubuda uye yekubuda nekumhanya, ine yakakwira dhigirii ye otomatiki, inokurumidza footage kumhanya uye yakakwirira kuvaka kugona.
5. Chimbo uye chidzitiro chekuratidzira mu cab chinoratidza data yekushanda yegadziriro yega yega munguva chaiyo, kuitira kuti mufambisi agone kubata mamiriro ekushanda chero nguva.

- Project process
Pombi suction reverse circulation drilling rig. Nekutenderera kwemvura, zvinhu zvekucheka mumurwi (tsime) gomba zvinoramba zvichiendeswa kugomba rematope pedyo nemurwi (tsime) gomba pamwe chete nedhaka. Mugomba rematope, jecha, dombo uye zvimwe zvinhu zvegranular zvinogara pasi petangi, uye madhaka anoyerera achipinda mumurwi (tsime) gomba nguva dzose. Wedzera mwero wemvura wegomba remurwi. Iyo chaiyo process scheme ndeiyi inotevera:
3.1. Chifukidzo chemurwi chinofanira kuiswa pagomba remurwi. Iyo murwi casing inogadzirwa nesimbi ndiro yakakura kupfuura 5mm, uye dhayamita rayo richava 100mm yakakura kupfuura dhizaini murwi (zvakanaka) gomba dhayamita. Kureba kwemurwi casing kunoenderana nemamiriro e geological. Mupendero wezasi wemurwi casing unofanirwa kuvigwa muvhu rekugara uye upfuure dhizaini yekumashure.
3.2. Kana iyo yekudzosera yakadzika zvakanyanya uye yekuchera kana basa remawoko risingashande, mushandisi anogona kunyanya kugadzira dhiri yekubooresa uye kuigadzirisa pachibhorani kuchera makomba. Kudzika hakuwanzo kudarika 10m. Sezvingave zvakadaro. Usapunzika.
3.3. Kukwanisa kuchera kwegomba rematope kuchava kukuru kudarika vhoriyamu yegomba remurwi. Zviri nani kushandisa rectangular chimiro, iyo inogona kurebesa nguva uye kumhanya kwedhaka reflux mugomba remurwi, uye iyo granular zvinhu inogona kugadzikana kusvika pakakwirira.
