1. Tom qab lub tshuab hluav taws xob tau txais lub teeb liab hloov pauv los ntawm kev tswj hwm lub cev, lub cev muaj zog tsis tig thiab muaj lub suab humming. Cov laj thawj yuav yog:
1) Lub ntiaj teb iav ib feem ntawm cov hluav taws xob actuator reducer yog jammed, puas los yog deformed;
2) Lub helical iav kis tau tus mob ib feem ntawm cov hluav taws xob actuator reducer yog deformed los yog hnyav heev hnav los yog puas;
3) Deformation thiab kev puas tsuaj, jamming, thiab lwm yam ntawm lub turbine worm los yog ntsia hlau ntsia hlau kis tau tus mob ib feem ntawm cov hluav taws xob actuator reducer;
4) Tag nrho cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob tsis zoo sib koom ua ke thiab hloov tsis tau, thiab yuav tsum tau hloov kho thiab refueled.
