Fais Actuator Tsav Failure Troubleshooting Flowchart
1. Ua ntej txheeb xyuas cov khoom siv hluav taws xob thiab xaim hluav taws xob (40-50% ntawm qhov tsis raug tshwm sim ntawm no)
- Anomaly: Kho fais fab mov / xaim
- Ib txwm: mus rau kauj ruam tom ntej
2. Txheeb xyuas cov teeb liab kis tau tus mob (Controller → Tsav tsheb)
- Anomaly: Kho/pab tswj qhov system
- Ib txwm: mus rau kauj ruam tom ntej
3. Tshawb xyuas qhov xwm txheej ntawm cov khoom siv tshuab
- Anomaly: daws txhua yam jamming/obstruction
- Normal: Ua nyob rau hauv - qhov tob soj ntsuam lub cev muaj zog lossis kev kuaj mob tshaj lij
Cov ncauj lus kom ntxaws ua txhaum cai thiab cov kev ntsuas kho
1. Cov teeb meem muab hluav taws xob (feem ntau yog vim li cas)
· Cov tsos mob: Lub cev muaj zog tsis teb; qhov taw qhia teeb tsis illumination.
Cov kauj ruam daws teeb meem:
Ntsuas qhov hluav taws xob: Xyuas kom tseeb tias qhov hluav taws xob qhov hluav taws xob yog qhov ruaj khov thiab ua tau raws li cov lus qhia tshwj xeeb (xws li, kos rau theem poob, undervoltage, los yog ntau dhau voltage fluctuation).
Tshawb xyuas Wiring:
- Xyuas seb lub tshuab hluav taws xob puas tau poob lossis yog lub fuse tau tawg.
- Siv lub megohmmeter los ntsuam xyuas kev txuas mus ntxiv / kev ncaj ncees; tshawb xyuas cov khoom txuas xoob, cov kab laus laus, lossis luv luv. Kev daws: Hloov cov kab hluav taws xob puas; kho lub hwj chim voltage regulator.
2. Lub cev muaj zog Internal Faults
· Winding puas:
- Diagnostics: Siv lub megohmmeter los ntsuas kev tiv thaiv rwb thaiv tsev; siv ib tug multimeter los ntsuas coil kuj.
- Kev daws: Rewind lub motor coils. ...rewind the coils or replace the motor.
· Seized Bearings:
. Cov tsos mob: Nyuaj manually tig lub cev muaj zog ncej, nrog rau cov suab nrov txawv txav.
. Kev Kho: Ntxuav thiab siv cov roj nplua nyeem; hloov cov bearings thaum hnav hnyav.
3. Tswj System Anomalies
· Tswj Failure:
. Xyuas kom tseeb tias cov zis tawm los ntawm PLC lossis tswj module yog qhov qub.
. Pib dua tus maub los lossis hloov cov khoom puas.
· Tsav teeb meem:
. Xyuas kom tseeb tias cov tsav tsis (piv txwv li, txwv tam sim no, lub sij hawm acceleration) raug sib raug zoo.
. Ntsuam xyuas cov kev sib cuag relay los xyuas seb qhov nplaum los yog vuam.
4. Mechanical Obstructions
· Seized Valve:
. Manually khiav lub valve kom paub meej tias nws txav tau yooj yim.
. Kev Kho: Tshem tawm impurities los ntawm cov kav dej; hloov lub sealing rings los yog valve qia.
· Transmission Mechanism Failure:
. Kos lub gearbox roj theem thiab coupling alignment; hloov cov yuam sij tawg lossis tus pins.
5. Lwm yam ua rau
· Kev tiv thaiv overload:
. Pib dua lub thermal overload relay; xyuas seb lub load tshaj qhov specifications (xws li, valve torque > actuator rating).
· Environmental Factors:
. Kub kub ua rau lub cev muaj zog tiv thaiv overheat: Txhim kho qhov cua los yog nruab cov dab dej kub.
. Cov av noo ua rau hluav taws xob luv luv: Siv cov dej noo- cov ntaub ntawv pov thawj kaw.
