Inqubo entsha yomshini wepiston ngesando se-DTH

Inqubo entsha yomshini wepiston ngesando se-DTH

Okokuqala, isimo samanje se-piston ye-perforator

Ngokombono womthwalo othwelwe i-piston, i-piston idinga ukuba nokunemba okuphezulu nokuphela kwendawo,

ukuze ibe nomphumela omuhle wokuvala futhi ivumelane nezici zokunyakaza okuphindaphindayo kwe-high-frequency; ngesikhathi esifanayo,

idinga ukuba nesakhiwo esiphusile kanye nokwelashwa okuhle kokushisa, ukuze ikwazi ukudlulisa ngempumelelo amandla omthelela futhi

inokumelana okuphezulu nokuhuzuka komshini kanye nokumelana nomthelela.

1 Ukuhlaziywa kwethiyori ye-Piston force

Nge-hole hammer piston impact bit, ngesikhathi esifushane kakhulu, isivinini sokunyakaza kwayo (usayizi kanye nesiqondiso)yashintsha ngokuphawulekayo, ekushintsheni okusheshayo kusayizi kanye nesiqondiso saso sonke isikhathi ngaphansi kwesenzo sezinguquko ze-cyclical emthwalweni onamandla,

i-piston's strain ayiyona i-uniform strain, ukunyakaza kwesisindo akusona isivinini esiphelele, isivinini kanye nesivinini kuyasakazwa.

ngendlela yamagagasi okucindezeleka. Enqubweni yokumba i-rotary, isando esingaphansi kwamanzi sisebenzisa umthelela wepiston ukudlulisa ingcindezi.

qhweba edwaleni ngaphansi kwembobo ngokusebenzisa i-drill bit ukuze ubone ukubhoboza idwala. I-piston yesando esicwilisiwe sinokushintshashintsha

isakhiwo se-cross-section, lapho igagasi lokucindezeleka lisakazeka futhi libophekile ukuba liguqulwe ekushintsheni kwesigaba esiphambanayo, hhayi kuphela ekupheleni kwesando.

Nakuba isando sesigaba esilinganayo singaphansi kwengcindezi ecindezelayo, isando sesigaba esiguquguqukayo asikho nje ngaphansi kwezingcindezi ezicindezelayo, kodwa futhi nezingcindezi eziqinile.

2 umthelela wokwenziwa kwepiston kanye nenqubo yokwelapha ukushisa

Ukusebenza kwe-piston okunomthelela kuhlobene kakhulu nenqubo yokukhiqiza. Izinto ezihlukene, inqubo yayo yokukhiqiza ihlukile.

( 1) insimbi ephezulu ye-carbon vanadium (efana ne-T10V) umzila wenqubo ye-piston yokukhiqiza ukuze kuhlolwe izinto zokusetshenziswa

(ukwakheka kwamakhemikhali, ukufakwa okuncane, okungeyona insimbi nokuba lukhuni) → impahla → ukubumba → ukwelashwa kokushisa → ukuhlola → ukugaya.

( 2) 20CrMo umzila wenqubo yepiston yokukhiqiza insimbi yokubumba → ukwenza kube ngokwejwayelekile → ukuhlola → umshini → ukwelapha ukushisa → ukuqhunyiswa kwesihlabathi → ukuhlola → ukugaya.

( 3) 35C Mnu oV umzila wepiston wokukhiqiza insimbi yokubumba → ukwelashwa kokushisa y ukuhlola ( ubulukhuni ) → umshini → ukungcwatshwa kwemoto → ukuhlola ( ungqimba olushisiwe )

→ ukushisa okuphezulu → ukucisha → ukuhlanza → ukushisa okuphansi → ukuqhunyiswa kwesihlabathi → ukuhlola → ukugaya.

3 Ukwehluleka kwe-piston

I-Piston ingamandla ayinkimbinkimbi ngaphakathi kwesando esicwilisiwe, kulula ukulimaza izingxenye. I-Piston ku-high-pressure gas drive, enomthelela wesivinini esikhulu, bese idlula

kancane kuya phansi emgodini we-rock umthelela wokudlulisa amandla. Inqubo yomthelela, i-piston ngobukhulu kanye nesiqondiso samandla ingeyezinguquko zezikhathi, cishe ibhakede elingu-100.

s ngaphakathi kwamandla akhuphuka ngokuzumayo afika kumathani amathani, noma ngaphezulu, futhi ngemva kwamakhulu ambalwa amasekhondi amancane, abese ehlehlela kuqanda. Ukuchayeka ku-

amandla omthelela osheshayo aphindaphindiwe, azokhiqiza ukugxila kwengcindezi kwezinye izingxenye zepiston, okuholela ekulimaleni kwepiston, lo monakalo ujwayelekile ekwakhiweni.

ukusebenza kwemishini enomthelela, ukuze ukwehluleka kwepiston, okufana: ukuphuka kwepiston, ukudangala kwekhanda le-piston, i-piston head metal spalling.

Ekuqaleni kwenqubo yokuhlola, impilo yokusebenza ye-piston ye-hammer piston iphansi kakhulu, ukuphuka okungaphezu kokukodwa, cishe konke ukuphuka ku-diameter encane.

izingxenye ze-piston, ezinye zine-longitudinalimifantu iqonde ekupheleni kobubanzi obuncane, Umfanekiso wesi-2 wokuphuka kwepiston yesithombe somzimba. Impilo yokusebenza kwe-

i-piston izothinta ngokuqondile ukusebenza kwesando esicwilisiwe ngokwaso kanye nokukhuthazwa kanye nokusetshenziswa kobuchwepheshe bokugaya isando esicwilisiwe, kanye

izizathu zokuphuka kwayo kufanele zihlaziywe kusukela kumandla akhethekile we-piston.

Okwesibili, inqubo entsha yomshini we-submariner piston machining

Imikhiqizo

I-HFD Mining Tools iyibhizinisi elisekelwe emisha ezimele, ezibophezele ekuthuthukiseni ukumelana nokugqokwa nempilo yesevisi yamabhithi nezando ze-DTH.

I-HFD Mining Tools ithuthukise ngempumelelo izingxenye eziwumgogodla zezando ze-DTH.

1, Isimiso Somkhiqizo

Ubuchwepheshe be-Metal surface crystal remodeling TM buwushintsho olusha kubuchwepheshe bokucubungula indawo yensimbi ngokombono wokucubungula isibuko, ikristalu.

ukulungisa kabusha, inqubo yocwaningo, ukuqedwa kwamaphutha ekristalu endaweni yensimbi. Ubuchwepheshe be-Crystal ResurfacingTM be-SPIRIT bunganciphisa kakhulu indawo

ukuqina nokuthuthukisa amandla okukhathala, ukuqina okuncane, ukumelana nemihuzuko, ukumelana nokugqwala nezinye izakhiwo zezindawo zensimbi. Ithuthukisa kakhulu isevisi

impilo ye-DTH Hammers.

I-2, i-DTH izando ze-piston metal surface ikhiqiza imiphumela eyisithupha:

1) Indawo yensimbi ingabona kalula umphumela wesibuko, Ra≤0.2μm.

2) Ukulungiswa kabusha kwekristalu yensimbi, ukucolisiswa okusanhlamvu.

3) Ubulukhuni obuncane bobuso bukhuphuke ngo-10% -30%.

I-4) Ukuqedwa kokukhubazeka kwekristalu nokwakheka kokucindezeleka okucindezelayo endaweni yensimbi.

5) Thuthukisa kakhulu ukumelana nokugqoka kanye nokumelana nokugqwala kwendawo yensimbi.

6) Khulisa ngokuphawulekayo ubude besikhathi sokuphila kwezingxenye zokuphumula komsebenzi.
