Njira yatsopano yopangira pisitoni ndi nyundo ya DTH

Choyamba, mkhalidwe wamakono wa pisitoni ya perforator

Poyang'ana katundu wonyamulidwa ndi pisitoni, pistoni iyenera kukhala yolondola kwambiri komanso yomaliza pamwamba,

kotero kuti imakhala ndi zotsatira zabwino zosindikizira ndikusintha kuti zigwirizane ndi machitidwe a maulendo apamwamba obwerezabwereza; nthawi yomweyo,

imayenera kukhala ndi kapangidwe koyenera komanso chithandizo chabwino cha kutentha, kuti ithe kusamutsa bwino mphamvu yamphamvu ndi

ali ndi kukana kwakukulu kwa makina abrasion ndi kukana mphamvu.

1 Piston force theory kusanthula

Kupyolera mu bowo la pistoni kukhudza pang'ono, m'kanthawi kochepa kwambiri, kuthamanga kwa kayendedwe kake (kukula ndi kolowera) kwakhala.zasintha kwambiri, pakusintha mwachangu kukula ndi mayendedwe anthawi zonse pansi pakusintha kwamayendedwe amphamvu,

kupsyinjika kwa pisitoni si yunifolomu kupsyinjika, kusuntha kwa misa sikuli liwiro lonse, kuthamanga ndi liwiro zimafalitsidwa.

mwa mawonekedwe a mafunde opanikizika. Pobowola mozungulira, nyundo yomira pansi imagwiritsa ntchito mphamvu ya pisitoni kufalitsa kupsinjika.

gwedezani thanthwe pansi pa dzenje kudzera pobowola kuti muzindikire kubowola kwa thanthwe. Pistoni ya nyundo yomira ili ndi kusintha

mawonekedwe a mtanda, momwe phokoso lachisokonezo limafalikira ndipo liyenera kusinthidwa pa kusintha kwa gawo, osati kumapeto kwa nyundo.

Ngakhale nyundo ya gawo lofanana imakhala ndi kupsinjika kwapang'onopang'ono, nyundo ya gawo losinthika silimangokhala ndi kupsinjika, komanso kupsinjika kwamphamvu.

2 imakhudza kupanga pisitoni ndi njira yochizira kutentha

Kuchita kwa piston kumagwirizana kwambiri ndi kupanga kwake. Zida zosiyanasiyana, kupanga kwake kumakhala kosiyana.

(1) high carbon vanadium zitsulo (monga T10V) kupanga pisitoni njira njira yoyendera zopangira

(mankhwala opangidwa ndi mankhwala, micro, non-metallic inclusions ndi kuuma) → zakuthupi → kupanga → kutentha kutentha → kuyang'ana → kugaya.

( 2) 20CrMo zitsulo zopangira pisitoni njira yopangira → yokhazikika → kuyang'ana → kukonza → kutentha kutentha → kuphulika kwa mchenga → kuyang'ana → kugaya.

( 3) 35C Mr oV zitsulo kupanga pisitoni njira yopangira → chithandizo cha kutentha y kuyang'anira ( kuuma ) → makina → carburizing → kuyendera ( carburized layer )

→ kutentha kwambiri → kuzimitsa → kuyeretsa → kutentha pang'ono → kuphulika kwa mchenga → kuyang'anira → kugaya.

3 Kulephera kwa piston

Piston ndi mphamvu yovuta mkati mwa nyundo yomira, yosavuta kuwononga ziwalo. Piston mu galimoto yothamanga kwambiri ya gasi, yokhala ndi liwiro lalikulu, kenako ndikudutsa

pang'ono pansi pa dzenje thanthwe zimakhudza mphamvu kutengerapo. Impact ndondomeko, pisitoni ndi kukula ndi malangizo a mphamvu ndi kwa nthawi kusintha, pafupifupi 100 ndowa.

s mkati mwa mphamvuyo idakwera mwadzidzidzi mpaka matani ambiri, kapena kupitilira apo, kenako pambuyo pa ma microseconds mazana angapo, kenako kubwerera ku ziro. Kuwonetsedwa kwa nthawi yayitali

mphamvu yobwerezabwereza pompopompo, idzatulutsa kupsinjika m'magawo ena a pistoni, zomwe zimapangitsa kuwonongeka kwa pisitoni, kuwonongeka kumeneku kumakhala kofala pakumanga.

ntchito zamakina okhudzidwa, kotero kuti kulephera kwa pisitoni, monga: kuthyoka kwa pisitoni, kupsinjika mutu wa pisitoni, pisitoni mutu wachitsulo spalling.

Kumayambiriro kwa mayeso, moyo wogwira ntchito wa pistoni yodutsa-bowo ndi yotsika kwambiri, kuphulika kopitilira kumodzi, pafupifupi fracture iliyonse imakhala m'mimba mwake yaying'ono.

mbali za pisitoni, zina zimakhala zotalikaming'alu molunjika mpaka kumapeto kwa mainchesi ang'onoang'ono, Chithunzi 2 cha kupasuka kwa pistoni ya chithunzi chakuthupi. Moyo wogwira ntchito wa

pisitoni ikhudza mwachindunji magwiridwe antchito a nyundo yomizidwa yokhayokha komanso kukwezedwa ndikugwiritsa ntchito ukadaulo wobowola nyundo womira, ndi

zifukwa za kusweka kwake ziyenera kufufuzidwa kuchokera ku mphamvu yapadera ya pistoni.

Chachiwiri, njira yatsopano yopangira pisitoni ya submariner


Zogulitsa

HFD Mining Tools ndi bizinesi yozikidwa pazatsopano zodziyimira pawokha, zomwe zadzipereka kuti zithandizire kukana kuvala komanso moyo wautumiki wa ma bits ndi nyundo za DTH.

HFD Mining Tools yapanga bwino zigawo zikuluzikulu za nyundo za DTH.

1, Mfundo Yopangira

Ukadaulo wa Metal surface crystal remodeling TM ndikusintha kwaukadaulo muukadaulo wazitsulo wazitsulo kuchokera pamawonekedwe a galasi, kristalo.

kukonzanso, ndondomeko ya kafukufuku, kuthetsa zolakwika za kristalo pamtunda wachitsulo. Ukadaulo wa SPIRIT's Crystal ResurfacingTM ukhoza kuchepetsa kwambiri pamwamba

roughness ndi bwino kutopa mphamvu, microhardness, abrasion kukana, dzimbiri kukana ndi zina katundu zitsulo. Zimathandizira kwambiri utumiki

moyo wa DTH Hammers.

2, DTH nyundo pisitoni zitsulo pamwamba umapanga zotsatira zisanu ndi chimodzi:

1) Pamwamba pazitsulo amatha kuzindikira mosavuta galasi, Ra≤0.2μm.

2) Kukonzanso kwachitsulo pamwamba pa kristalo, kukonzanso tirigu.

3) Kulimba kwapang'onopang'ono kumawonjezeka ndi 10% -30%.

4) Kuchotsa zolakwika za kristalo ndikupanga kupsinjika kwapakatikati pazitsulo.

5) Kuwongolera kwambiri kukana kuvala ndi kukana kwa dzimbiri kwazitsulo.

6) Onjezani kwambiri kutalika kwa moyo wa magawo kuti muchepetse ntchito.
