| Karkashin Torquing | Sake girgizawa, rabuwar haɗin gwiwa | Aiwatar dace preload, amfani da mahadi masu kulle zare |
Magani: Follow karfin juyi charts dangane da abu da lubrication.
Haɗaɗɗen Hydrogen (HE)
Babban damuwa ga maɗaurin ƙarfe mai ƙarfi, cewa atom ɗin hydrogen suna raunana ƙarfe.
| Sanadin | rigakafin |
|---|---|
| Electroplating (misali, kusoshi mai rufi na zinc) | Gasa fasteners bayan plating don cire hydrogen |
| Bayyanawa ga yanayin acidic | amfani ba-electroplated coatings (misali, Dacromet) |
Magani: Don aikace-aikace masu mahimmanci, amfani suturar da ba ta da hydrogen ko canza zuwa titanium / nickel gami.
Zaɓin Kayan da ba daidai ba
Yin amfani da kayan maɗauri mara kyau don aikace-aikacen na iya haifar da gazawar da wuri.
| Halin rashin daidaituwa | Nasihar Madadin |
|---|---|
| Carbon karfe a cikin ruwan gishiri | Bakin karfe (316) ko titanium |
| Aluminum a cikin zafi mai zafi | Alloy na nickel (Inconel 600) |
| Filastik a ƙarƙashin kaya | High-ƙarfi gami fasteners |
Magani: shawarci sigogin dacewa kayan aiki kafin zabe.
Kammalawa: Yadda ake Tabbatar da Amincewar Fastener
Don haɓaka tsawon rayuwar fastener:
- Zabi kayan da suka dace (alloys masu jure lalata don yanayi mara kyau)
- Aiwatar da madaidaicin juzu'i (amfani da kayan aikin calibrated, bi ƙayyadaddun bayanai)
- Yi amfani da hanyoyin hana sassautawa (kulle washers, adhesives)
- Duba akai-akai (duba lalata, fashe gajiya)
At Fasahar TSM, mun bayar high-yi fasteners in titanium, nickel gami da bakin karfe, tabbatar da dorewa a cikin mafi yawan yanayi.
