Ingabe kuyabiza ukulungisa ibhawodi eliphukile embhoshongweni wenjini yomoya? Zama izikhonkwane zensimbi engagqwali engu-A4-80

Embonini yamandla omoya, ukwethembeka kwamabhawodi ombhoshongo kuthinta ngqo ukusebenza okuphephile nokugcinwa kwezindleko zeyunithi. I-carbon steel yomdabu noma amabhawodi ensimbi engagqwali ajwayele ukuphuka, ukugqwala kanye nokuxega ngaphansi kwemithwalo yesikhathi eside yomoya kanye nezindawo zokudlidliza, okuholela ekulungisweni njalo nokulahlekelwa kokuphehlwa kwamandla. Izikhonkwane zensimbi engagqwali engu-A4-80 ziba yisixazululo esithandwayo sokuthuthukisa ukwethembeka embonini yamandla omoya ngenxa yezakhiwo zazo ezinhle kakhulu zemishini kanye nokumelana nokugqwala.

Izindlela zokuhluleka ezijwayelekile zamabhawodi wamandla omoya

1. Ukuphuka kokukhathala: Umbhoshongo ungaphansi kwemithwalo eshintshanayo ngesikhathi sokusebenza, futhi amabhawodi akhiqiza ama-microcracks futhi anda ngaphansi kwengcindezi ephindaphindiwe.

2. Ukwehluleka okuxekethile: Ukudlidliza kubangela ukulayisha kuqala kubole, futhi ukuguga kwe-micro-motion kwenzeka ezingxenyeni zokuxhuma.

3. Ukugqwala kwengcindezi: Imvelo yesifutho sikasawoti yamapulazi omoya asogwini isheshisa ukuqaliswa kokuqhekeka

4. Ingozi ye-hydrogen embrittlement: Izinqubo ezingalungile zokwelashwa kokushisa zingaholela ekubambezelekeni kokuphuka

Izinzuzo zobuchwepheshe ze-A4-80 grade stainless studs

1. Amandla aphezulu kakhulu: Amandla amancane aqinile angama-800MPa, acishe abe ngama-30% ngaphezu kwensimbi engagqwali engu-304 evamile.

2. Ukuqina okuhle kakhulu: ngemuva kokwelashwa kokushisa kwesisombululo, ubude ≥15%, ukumelana nomthelela omuhle kakhulu

3. Ukumelana nokugqwala: I-substrate yensimbi engagqwali engu-316, ukusebenza okuhle kakhulu endaweni yokufutha usawoti

4. Ukunemba kokucubungula: ukwakheka okugoqekayo okugcwele, okuqinisekisa ukunemba kobukhulu kanye nekhwalithi ephezulu

Ukuqinisekiswa kwezinkomba zobuchwepheshe ezibalulekile

Ukuhlolwa kwezakhiwo zikamshini:

Amandla we-Tensile: 810-850MPa

Amandla okukhiqiza: ≥640MPa

Ukuqina: HV230-280

Ukuhlolwa kokugqwala:

Ukuhlolwa kwesifutho sikasawoti esimaphakathi: amahora angama-2000 ngaphandle kokugqwala okubomvu

Ukuhlolwa kokugqwala kwengcindezi: ngokuhambisana nezinga le-ISO 3506

Ukusebenza kokukhathala:

Ngaphansi kobubanzi obulinganayo bomthwalo weminyaka engu-20, impilo yokukhathala ihlangabezana nezidingo zedizayini

Iziphakamiso zokukhetha

Ukuqinisekisa okubalulekile:Idinga abahlinzeki ukuthi banikeze isitifiketi sempahla ukuze kuqinisekiswe ukuthi okuqukethwe kwe-Mo kungu-≥2.1%

Ukuqinisekisa inqubo:

Hlola ukuthi ingabe ilashwe ngesisombululo sokushisa

Qinisekisa inqubo yokwelapha i-surface passivation

Amaphoyinti okufaka:

Sebenzisa indlela ye-engeli ye-torque ukuze ulawule ukulayisha kuqala

Kunconywa ukusebenzisa ama-gaskets anti-loosening

Iziphakamiso zesondlo:

Hlola njalo isimo sokulayisha kuqala

Sungula ifayela lokumiselela umshudo

Ukuqinisekiswa kwesicelo semboni

Ngokombiko we-ejensi yokuhlola yenkampani yangaphandle, ngaphansi kwezimo ezifanayo zokusebenza:

1. Impilo yesevisi yezikhonkwane zensimbi engagqwali engu-A4-80 iphindwe izikhathi ezi-3-5 kunaleyo yamabhawodi ensimbi ekhabhoni ajwayelekile.

2. Isikhathi sokulungisa singanwetshwa sibe ngaphezu kweminyaka emi-5

3. Izindleko zomjikelezo wempilo ephelele zehliswa ngaphezu kuka-40%

Silandela ngokuqinile i-ISO 3506, ama-ASTM A4-80 grade grade stainless steel studs akhiqizwa ngokuvumelana namazinga omhlaba afana ne-A193, futhi ahlinzeke:

1. Gcwalisa imibhalo yesitifiketi sempahla

2. Umbiko wokuhlola izakhiwo zemishini

3. Izitifiketi zesitifiketi somuntu wesithathu (njenge-DNV, TUV, njll.)

Uma udinga imininingwane yobuchwepheshe enemininingwane noma ukuhlolwa kwesampula, sicela ukhululeke ukuxhumana nathi.
