Hordhac Guud:

Dubeyaasha PLATO DTH waa dhammaan qaab-dhismeed fudud, fududahay in la isku keeno oo la kala diro, iyo sidoo kale tayo la isku halleyn karo iyo nolol adeeg oo dheer. Acedrills waxay leedahay noocyo dubbe oo kala duwan oo ku habboon in lagu qodo godadka 64mm ilaa 1000 mm (2-1 / 2" ~ 39-3 / 8") dhexroor; oo la yimaada saddex nooc: cadaadis hoose (5 ~ 7 bar), cadaadiska dhexe (7 ~ 15 bar) iyo cadaadis sare (7 ~ 30 bar).

Dubeyaasha PLATO DTH inta badan waxaa lagu soo saaraa nooca shank ah ee DHD, QL, SF, COP, Mission, SD, BR, CIR iyo taxanaha ACD, dhexroor u dhexeeya 2 "ilaa 8" macdanta iyo dhagaxa, iyo 6" ilaa 32" biyaha. -Ceel qodista, qodista ceelasha saliidda iyo aasaaska iyo wixii la mid ah;

Xulashada Hammer DTH:

Doorashada dubbe saxda ah waxaa inta badan go'aamiya mishiinada daloolista (inta badan kombaresarada), cabbirka daloolka daloolka iyo nooca samaynta dhagaxa. Sida habboon, cabbirka dubbehu waa inuu u dhigmaa cabbirka daloolka loo baahan yahay sida ugu dhow ee suurtogalka ah, isaga oo ka tagaya meel ku filan hawo ciriiri ah si ay u nadiifiso gooynnada una nadiifiso daloolka.

Baaxadda ugu wanaagsan ee cabbirka daloolka qodista godka qaraxa ee leh habka DTH waa 90 ~ 254 mm (3-1/2" ~ 10") oo leh 3.5 ~ 8" dubbe. Daloollada yaryar ee qarxa ayaa guud ahaan lagu qodaa qalab dubbe-sare ah, halka daloollada waaweyni ay sida caadiga ah wataan aaladaha qodida wareegta ah. Codsiyada kale, sida qodista aasaaska, dubbaha DTH waxaa loo isticmaali karaa cabbirka daloolka ilaa 1,000 mm (39-3/8").

Caadiyan, dhexroorka daloolka ugu yar ee dubbe DTH uu qodi karo waa cabbirkiisa magac ahaan, tusaale ahaan, dubbe 4 "wuxuu daloolin doonaa 4" (100/102 mm). Qodobka xaddidaya waa dhexroorka dibadda ee dubbaha, sababtoo ah, sida dhexroorka daloolka hoos u dhaco, socodka hawadu waa xaddidan yahay. Cabbirka daloolka ugu badan ee qodista wax soo saarka waa cabbirka dubbe magaca ah oo lagu daray 1 "loogu talagalay 5" iyo dubbaha yaryar iyo 2 ee 6" iyo dubbaha waaweyn, tusaale ahaan, dubbe 4" cabbirka daloolka ugu badan waa 5" (127/130mm) halka dubbe 8" ah cabbirka daloolka ugu badan uu yahay 10" (254mm).

Silsilad qalab qodista PlaTO DTH

PLATO waxay ku jirtaa booska si ay u siiso macaamiisha qaybo buuxa oo kala duwan oo loogu talagalay silsiladaha qalabka qodista DTH, oo ay ku jiraan dubbaha DTH, bits (ama qalabyada u dhigma qalabka shaqada), adabiyeyaasha hoose, tuubooyinka daloolista (ulaha, tuubooyinka), dubbaha RC iyo biraha, laydhka laba- gidaarka tuubooyinka iyo kuraasta jaban dubbe iyo wixii la mid ah. Qalabkayaga Qodista DTH sidoo kale si fiican ayaa loogu qaabeeyey oo loo soo saaray qodista, warshadaha qodista ceelasha biyaha, sahaminta, dhismaha iyo injineernimada madaniga ah.

Habka hoos-the-hole (DTH) wuxuu ahaa osi lama filaan ah loo horumariyay si loo qodo godad waaweyn oo dhexroor ah oo hoos u ah codsiyada qodista dusha sare, magaceeduna wuxuu ka yimid xaqiiqda ah in habka garaaca (dubbada DTH) ay isla markiiba hoos u raacdo godka, halkii ay ku sii jiri lahayd quudinta sida caadiga ah. dabaasha iyo jackhammers.

Nidaamka qodista DTH, dubbaha iyo birta ayaa ah hawlgalka aasaasiga ah iyo qaybaha, dubbuhuna wuxuu si toos ah ugu yaalaa gadaashiisa qashin-qubka oo hoos u shaqeeya godka. Bisitoonku waxa uu si toos ah u garaacayaa dusha sare ee qaniinyada, halka daboolka dubbehu uu si toos ah oo xasiloon u hagi doono qaniinyada laydhka. Tani waxay la macno tahay in aanay wax saamayn ah ku yeelan tamar ka go'aysa kala-goysyada dhammaanba xadhigga layliga. Saamaynta tamarta iyo heerka gelitaanka sidaas darteed ayaa ah mid joogto ah, iyada oo aan loo eegin qoto dheeraanta godka. Piston-ka daloolku waxa uu ku shaqeeyaa hawo cufan oo la soo mariyo ulaha marka loo eego cadaadiska sahayda ee u dhexeeya 5-25 bar (0.5-2.5 MPa / 70-360 PSI). Matoor sahal ah oo sambabada ama haydarooliga ah oo lagu rakibay giraangiraha dusha sare ayaa soo saara wareeg, gooyn gooyn waxaa lagu gaaraa hawada qiiqa ka soo baxda dubbaha ama hawo cadaadis leh oo lagu durayo ceeryaamo biyo ah ama hawo miinada caadiga ah oo leh boodh ururiye.

Tuubooyinka daloolku waxay u gudbiyaan xoogga quudinta lagama maarmaanka ah iyo wareegga wareegga habka saameynta (dubbada) iyo qaniinyada, sidoo kale waxay gudbiyaan hawo ciriiri ah oo dubbaha iyo nadiifinta gooyn iyada oo hawada qiiqa ah ay afuufto daloolka oo ay nadiifiso oo kor u qaaddo goynta. godka. Tuubooyinka daloolka ayaa lagu daraa xadhigga laydhka si isdaba joog ah uga dambeeya dubbaha marka daloolku sii qoto dheeraado.

Qoditaanka DTH waa hab aad u fudud oo loogu talagalay hawl-wadeenada qodista godka qoto dheer iyo tooska ah. Inta u dhaxaysa godka 100-254 mm (4 "~ 10"), qodista DTH waa habka ugu badan ee qodista maanta (gaar ahaan marka qotodheerta godku ka weyn yahay 20 mitir).

Habka qodista DTH ayaa caan ku ah, iyada oo ay korodhay dhammaan qaybaha codsiga, oo ay ku jiraan godka qaraxa, ceelka biyaha, aasaaska, saliidda & gaasta, hababka qaboojinta iyo qodista matoorada kulaylka. Codsiyada ayaa markii dambe laga helay dhulka hoostiisa, halkaas oo jihada qodista ay guud ahaan kor u kacdo halkii ay hoos u dhici lahayd.

Tilmaamaha ugu muhiimsan iyo faa'iidooyinka qodista DTH (inta badan marka la barbardhigo dubbaha sare):

1.Wide cabbirka godadka, oo ay ku jiraan dhexroor godad aad u weyn;

2.Dib-u-noqosho heer sare ah oo gudaha 1.5% ah oo aan lahayn qalab hagaya, oo ka saxsan dubbaha sare, sababtoo ah saameynta ku jirta godka;

3.Nadiifinta godka wanaagsan, oo leh hawo badan oo loogu talagalay nadiifinta daloolka ka soo dubbaha;

4.Good dalool tayo leh, oo leh derbiyo siman iyo xitaa dalool si fudud loogu dallaco walxaha qarxa;

5.Simplicity ee hawlgalka iyo dayactirka;

6.Efficient tamar gudbinta iyo awoodda qodista god qoto dheer, oo leh dhexgalka joogtada ah iyo wax khasaare tamar ah ee kala-goysyada iyada oo loo marayo xadhigga laydhka laga bilaabo bilawga ilaa dhammaadka godka, sida dubbaha sare;

7.Waxay abuurtaa qashin-qubka oo yaraada, jabsiga sare oo yaraada, baasaska macdanta oo yaraada iyo xidhidhsiga

8.Qiimaha hoose ee isticmaalka ul qodista, iyadoo ay ugu wacan tahay xadhkaha laydhka laguma sarifo xoog xoog leh sida dubbe sare ee qodista iyo nolosha xadhigga laydhka ayaa sidaas awgeed si weyn loo dheereeyey;

9. La dhimay khatarta ah in lagu xayiro xaaladaha dhagaxyada jaban iyo cilladaysan;

10. Heerka qaylada hoose ee goobta shaqada, sababtoo ah dubbe hoos u shaqeynaya godka;

11. Heerarka gelitaanka ayaa ku dhawaad ​​si toos ah u dhigma cadaadiska hawada, sidaas darteed labanlaabida cadaadiska hawadu waxay keeni doontaa qiyaastii labanlaab dhexgalka.
