1. Gabatarwa

Makullan flange suna wakiltar wani muhimmin nau'i na masu ɗaurin masana'antu, haɗa aikin madaidaicin kusoshi tare da haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-haɗe-kamar flange a ƙasan kan soket. Lokacin da aka haɗa su tare da fasahar suturar Dacromet, waɗannan masu ɗaure suna samun ingantacciyar ma'auni na ƙarfin injina da juriya na lalata, yana sanya su zama makawa a cikin yanayin da ake buƙata kamar masana'antar kera motoci, gini, injiniyan ruwa, da injuna masu nauyi.

Wannan labarin yana ba da cikakken gwajin Dacromet mai rufi flange bolts daga madaidaitan ra'ayoyi guda biyu: ƙirar tsari da kaddarorin injin flange, da fasahar jiyya ta ci gaba da aka sani da Dacromet. Tare, waɗannan abubuwan suna bayyana mafita mai ɗaure wanda ya dace da ƙaƙƙarfan buƙatun aikace-aikacen injiniya na zamani.

2. Fahimtar Flange Bolts

Ƙaƙwalwar flange babban abin ɗaure mai zare wanda ke nuna faffadan flange hadedde kai tsaye ƙarƙashin kan hexagonal. Wannan flange yana rarraba nauyin matsawa akan wani yanki mafi girma, yana kawar da buƙatar mai wanki daban da rage lokacin haɗuwa. Haɗaɗɗen flange kuma yana ba da ingantaccen juriya ga sassautawa a ƙarƙashin girgiza, la'akari mai mahimmanci a cikin mahallin kaya mai ƙarfi.

Ana kera bolts na flange a cikin bambance-bambancen serrated da waɗanda ba safai. Serared flange bolts suna da hakora a ƙarƙashin flange wanda ke riƙe saman mating, yana ba da ingantaccen aikin hana girgiza. Siffofin da ba a haɗa su ba suna ba da ƙasa mai santsi, dacewa da aikace-aikace inda dole ne a rage lalacewar ƙasa.

Dacromet wani ci-gaba ne na tushen ruwa, fasaha mara amfani da sararin samaniya wanda aka samo asali don magance iyakokin galvanizing na al'ada. Rufin ya ƙunshi flakes na zinc, flakes na aluminum, da mahaɗan chromate da aka tarwatsa a cikin tsarin ɗaure mai ruwa. Lokacin shafa da warkewa, waɗannan ɓangarorin suna samar da shinge mai yawa, shinge mai shinge wanda ke ba da kariya ta musamman ta lalata ba tare da haɗarin ɓarkewar hydrogen ba.

Tsarin suturar Dacromet ya bambanta da gaske daga electroplating. Maimakon ajiye karfe ta hanyar lantarki, Dacromet yana amfani da aikace-aikacen dip-spin ko spraying wanda ke biye da yanayin zafi mai zafi. Yayin da ake warkewa a kusan 280-320 digiri Celsius, zinc da aluminum flakes sinter tare da haɗin kai ga ma'aunin ƙarfe ta hanyar hanyar haɗin kai mai tsaka-tsaki mai chromate. Sakamakon da aka samu yana da bakin ciki (yawanci 6-10 microns), uniform, kuma mai mahimmanci.

3.1 Bayanin Tsarin Rufe

Tsarin aikace-aikacen Dacromet ya ƙunshi matakai da yawa waɗanda aka sarrafa daidai, kowannensu yana ba da gudummawa ga halayen aikin ƙarshe na sutura:

Tebur 2. Matakan Tsarin Rufe Dacromet

Mataki	Tsari	Bayani

Rufe Uniform: Hanyar aikace-aikacen tsoma-spin tana tabbatar da daidaiton kauri ko da akan hadaddun geometries, gami da wuraren da aka zare da kuma wuraren ajiyewa inda wutar lantarki na iya samar da madaidaicin adibas.

Yarda da Muhalli: Tsarin Dacromet na zamani ba su da chromium hexavalent (Cr6+), suna bin umarnin RoHS, ELV, da REACH, yana sa su dace da aikace-aikacen motoci da na lantarki.

5. Masana'antu Aikace-aikace

Dacromet mai rufi flange bolts suna samun amfani mai yawa a cikin masana'antu da yawa inda duka daidaiton tsarin da kariyar lalata ta dogon lokaci ke da mahimmanci:

Masana'antar Kera Motoci: Ana amfani da shi a cikin majalissar chassis, hawan injin, tsarin birki, da abubuwan dakatarwa inda babban ƙarfi mai ƙarfi hade da juriya na feshin gishiri yana da mahimmanci. Manyan OEMs suna ƙayyadad da kayan ɗamara mai rufaffiyar Dacromet don aikace-aikacen ƙarƙashin jikin da aka fallasa ga gishiri da danshi.

Gina da Kayan Aiki: Yin aiki a cikin haɗin ginin ƙarfe, abubuwan gada, da kayan aiki na waje inda ƙirar flange mai rarraba kai ta rage lokacin shigarwa kuma murfin Dacromet yana ba da sabis na kyauta na shekaru da yawa.

Marine da Offshore: Babban juriya na feshin gishiri na rufin Dacromet (har zuwa sa'o'i 3,000) ya sa waɗannan kusoshi su zama manufa don ginin jirgin ruwa, dandamalin teku, da kayan aikin doki da aka fallasa ga ci gaba da yanayin ruwan gishiri.

Makamashin Iska: Ana amfani da shi a cikin filayen hasumiya na injin turbine da taruka na nacelle inda babban ƙarfin bolting dole ne ya jure lodin cyclic da bayyanar muhalli sama da rayuwar sabis na shekaru 20+.

Hanyar jirgin ƙasa da injina masu nauyi: Ana amfani da su a cikin tsarin ɗora waƙa, kayan aikin locomotive, da kayan aikin hakar ma'adinai inda ake buƙatar juriyar girgiza da kariyar lalata lokaci guda.

Ba Da. Na gaba.
