Momwe Mungagwiritsire Ntchito Sitima Yapanjanji?

A Step-by{1}Step Guide for Railway Maintenance Professionals

⚠️ Kodi mumadziwa?Kugwiritsa ntchito ma wrench molakwika kumayambitsa 37% ya kulephera kwa zomangira njanji msanga. (UIC Technical Report 2024)

Zopangidwira:Oyang'anira zogula njanji, oyang'anira kukonza njanji, ndi akatswiri am'munda omwe amagwira ntchito ndi ma hydraulic sleeper bolt wrenches (YLB-850) pa zomangira za M22-M27.

🔧 Khwerero 1: Pre-Ntchito Yachitetezo & Yang'anani Zida

✅ Valani PPE: chipewa cholimba, magolovesi oletsa-kugwedera, magalasi oteteza chitetezo
✅ Yang'anani ma hydraulic hoses ndi mitu yazitsulo (214mm/234mm)
✅ Yesani kuyimitsidwa kwadzidzidzi ndi torque limiter
✅ Khazikitsani kuyimba kwa torque kukhala "0" - osayamba pa max setting

⚙️ Gawo 2: Kuyika & Kuyanjanitsa

Ikani wrench base pa chogona. Gwiritsani ntchitomakina anu-odzigwirizanitsa(± 15mm kulolerana) kuyika soketi pamutu wa bawuti. Pamalo otsika-opepuka (machubu, ntchito yausiku), yambitsani zomangidwa-muKuwala kwa ntchito ya LED.

🎯 Khwerero 3: Kukhazikitsa kwa Torque & Kuwongolera mayendedwe

Za Kulimbitsa:Khazikitsani ku 250–300 N·m (perEN 13481-1), sankhani "Clockwise", dinani choyambitsa - tool auto-zosintha kuchokera pa liwiro kupita ku torque mode.

Kwa Rusty Bolts:Yambani pa 50% torque → pulse mode → pang'onopang'ono onjezerani mpaka850 N·m pamwamba(Chinthu cha YLB-850). Osati "nyundo" ndi mphamvu zonse.

📊 Khwerero 4: Kuyang'anira Ntchito

Sungani manja onse pa zogwirira. Onani mawonekedwe a torque ya digito. Imani nthawi yomweyo ngati mukumva kugwedeza kapena kumva kugwedezeka kwakukulu. Mitundu iwiri-ya socket (mongaYLB-850) amakulolani kuti mugwiritse ntchito mabawuti awiri osayikanso - kupulumutsa 35% nthawi m'malo osinthira.
