valavu yopanga kukulitsa mu ningbo

Nyama ikagwiritsidwa ntchito kwa nthawi yayitali, malo osindikizira a valavu ya valavu ndi mipando ya valavu imatha ndipo kulimba kumachepa. Kukonza malo osindikizira ndi ntchito yayikulu komanso yofunika. Njira yayikulu yokonza ikupera. Pamaso opindika kwambiri, ndiye maphunziro oyamba pambuyo popera ndikupera.

Valani valavu ikuphatikiza kuyeretsa ndi kuyendera, njira yopukutira ndi kuyendera.

1, kuyeretsa ndi kuyendera njira

Yeretsani malo osindikizira mu poto yamafuta, kugwiritsa ntchito ntchito zoyeretsa kwa akatswiri, ndikusambitsa pansi kuti muwone zowonongeka zotsekemera. Ming'alu yobisika yokhala ndi diso lamaliseche imatha kutsimikizika ndi kuyang'ana utoto. Pambuyo poyeretsa, kuyenera kuyang'ana valavu ya valavu kapena pampando wa valavu kutsitsa pa kulumikizana, yang'anani ndi ofiira ndi pensulo. Kuyesa kofiyira, yang'anani malo osindikizira, kuti adziwe zomwe zili pafupi; kapena pensulo ndi valavu ya valavu yozungulira amataya mabwalo ochepa, kenako kutseka disc valve ndi valve Crourtion, onani mzere wa pensulo kuti akhumudwitse. Ngati zokwanira sizabwino, mbale yoyenera imatha kugwiritsidwa ntchito kuyesa valavu ya valavu kapena chipata chopindika ndi valavu yopindika, kuti mudziwe malo opukutira.

2, njira yopera

Njira yogaya siyingakhale yodula, mutu kapena mpando pazenera kapena dzenje lakuya nthawi zambiri mkati mwa 0.5mm, mutha kugwiritsa ntchito njira yopukutira kuti ikonzedwe. Njira yogaya imagawidwa kukhala yopukutira, kupera ndi kupera bwino.

Kukupera kovuta ndikuchotsa chikhomo cha zikanda, mawonekedwe, mfundo ndi zolakwika zina, kotero kuti malo osungika kuti apeze mawonekedwe opukutira ndi kutsiriza kwa malo opukutira. Kupukutira pogwiritsa ntchito chopukutira mutu kapena zopukutira, kugwiritsa ntchito pepala lambiri kapena tinthu tating'onoting'ono, kukula kwa 80 #, kukula kwakukulu, koma njira zodulira kwambiri, zodulira kwambiri. Chifukwa chake, kupenya kovuta bola ngati mutu wathyathyathya kapena mpando ungathe kuchotsedwa ku pock.

Mu mphero ndikuchotsa mawonekedwe owoneka bwino a chivundikiro, kuti mupitilize kupititsa patsogolo kuthwa ndi kumaliza. Kugwiritsa ntchito pepala labwino kapena gawo labwino kwambiri pathupi, kukula kwa tinthu tating'onoting'ono ta 280 # -w5, kukula kwakukulu, kudula pang'ono, kuthandizira kuchepetsa kuwuka; Nthawi yomweyo iyenera kusinthidwa ndi zida zofufuzira, zida zofufuzira ziyenera kukhala zoyera. Pambuyo popera, nthaka yolumikizana iyenera kufika kuunika. Monga pensulo kapena chipilala cha valavu mu msewu wowerengeka, mutu kapena mpando wotsutsana ndi kuwalako kutembenukira, mzere wa pensulo uyenera kutha.

Kupukutira bwino ndi gawo lotsiriza la kupera kwa valavu, makamaka kuti apititse patsogolo kumaliza kwa chipilala. Kupukuta koyenera kumatha kukhala w5 kapena freer micro ndi mafuta, palafesene ndi diluve ndi valve mutuwo pafupi ndi kupera kwa mavesi, kumakhala chiwonetsero, chimakhala cholumikizira pafupi ndi pafupi. Kupera nthawi zambiri mpaka 60-100 ° kapena kotero, kenako kutembenukira mbali inayo-90 ° kapena kupera kamodzi, Mzere woonda kwambiri wa bwalo, utoto kukhala wakuda ndi wakuda pomwe mafuta kenako ndikupaka pang'ono, kupukuta ndi feuze yoyera. Mukakupera, kenako bweretsani zipewa zina, pamsonkhanowu uziyenera kukhala posachedwa, kuti tisawononge mutu wopukutidwa.

Manja akukukuta mosasamala kanthu za kafukufuku woyipa kapena wabwino, amakhala kukweza konse, pansi; kuzungulira, kubwezeretsa; Kugonjetsedwa, kusinthira ndi ntchito zina kuphatikiza ndi zokuta. Cholinga chake ndikupewa kubwereza, chida choperewera ndikuwongolera kuti chikhale chopukusira, kusintha malo osindikizira ndi kumaliza. 3, gawo loyang'anira

Munjira yogaya nthawi zonse imayenda pang'onopang'ono, cholinga chake ndikuti kumbukirani, dziwani, kuti mupewe bwino kwambiri kuti mukwaniritse zofunikira zaukadaulo. Tiyenera kudziwa kuti mphamvu zopukutira zimayenera kugwiritsidwa ntchito kuzolowera kutsindika kosiyanasiyana monga zida zopukuta kuti zikhale zokukuta ndikuwonetsetsa kuti mukumwa.

Kupukutira kwamphamvu ndi ntchito yofunika kwambiri, muyenera kupitiliza kudziwitsa, mufufuze, ndipo nthawi zina zimakhala bwino, koma nthawi zina zimakhala zopumira, Ndodo yopukutira siyokhazikika, omangika, kapena ngodya ya chida chofufuzira imapatuka.

Popeza a Abrasive ndi msanganizo wosakaniza ndi wabrasive madzi, mafuta a Abrasity ndi mafuta wamba palafine ndi injini. Chifukwa chake, kusankha koyenera kokhudza gawo lofunikira kwambiri ndiko kusankha kolondola kwa abrasive. Kodi mungasankhe bwanji Valve yoyenera?

Alumina (al2o3) alumina, omwe amadziwikanso kuti Cloutum, kuuma kwake ndi kwakukulu, kugwiritsa ntchito kuli ponseponse. Nthawi zambiri amafalitsa chitsulo, mkuwa, chitsulo komanso chitsulo chosapanga dzimbiri.

Silicon Carbide (SIC) silicon Carbide ali ndi mitundu iwiri yobiriwira komanso yakuda, kuuma kwake ndikokwera kuposa alumina. Green silicon carbide pakukukuta carbide; Apicon a lilibec, carbide yokupsinjika zida ndi zida zofewa, monga chitsulo, mkuwa ndi zina zotero.

Boron Carbide (B4C) kuuma kokha kwa diamondi ufa ndi silika wovuta kuposa, makamaka m'malo mwa miyala ya diamondi ya diamondi, yopukutidwa chrome.

Chromium Oxide (CRONO3) Chromium Oxide ndi kuuma kwambiri komanso kovuta kwambiri, kumagwirizanitsa kupembedzera kwa chromium, kumagwiritsidwanso ntchito popukutira.

Iron Oxide (Fe2o3) imron in inso in ndiyabwino kwambiri, koma kuuma ndi kupera nkomiya ndizoyipa kuposa chromium oxide, cholinga chomwecho ndi chromium. Cholinga chofanana ndi chromium. Cholinga chofanana ndi chromium. Cholinga chofanana ndi chromium. Cholinga chomwecho ndi chromium
