Kev daws:
Hloov pulley tam sim ntawd (tsis txhob kho)
Siv cov- cov ntaub ntawv zoo (MC nylon lossis hlau alloy)
Xyuas kom cov load tsis tshaj qhov muaj peev xwm
7. Ntau lub suab nrov thiab kev vibration
Teeb meem:
Cov suab nrov txawv txav thaum lub sijhawm ua haujlwm crane.
Ua rau:
Hnav bearings
Kev tsis ncaj ncees
Groove hnav
Loose Cheebtsam
Kev daws:
Tshawb xyuas thiab hloov cov kabmob
Tshawb xyuas kev sib tw
Tighten tag nrho cov fasteners
Hloov cov ris tsho hnav
8. Ntxoov Nplooj
Teeb meem:
Hlau hlua plam tawm ntawm lub rubey groove.
Ua rau:
Qhov loj qhov zawj tsis raug
Kev vibration ntau dhau
Hnav groove puab
Kev daws:
Hloov pulley nrog qhov tseeb groove specification
Xyuas kom txoj hlua nruj
Txhim kho kev sib raug zoo
9. Overheating ntawm Pulley System
Teeb meem:
Pulley los yog bearing cheeb tsam ua kub thaum ua haujlwm.
Ua rau:
Kev sib txhuam ntau dhau
Tsis muaj lubrication
Tshaj dhau
Cov kabmob tsis ua haujlwm
Kev daws:
Txhim kho lubrication (steel pulleys)
Hloov cov bearings
Txo cov load
Siv cov khoom sib txhuam tsawg- xws li nylon
10. Fastener Loosening
Teeb meem:
Bolts los yog mounting qhov chaw yuav xoob thaum ua haujlwm.
Ua rau:
Kev vibration
Kev teeb tsa tsis zoo
Tsis muaj cov khoom siv xauv xauv
Kev daws:
Retighten tag nrho cov fasteners
Siv cov txiv ntoo xauv los yog xov xauv
