Re-calibrate disc caij nplooj ntoos hlav preload rau rated nqi; 4. Reface lossis hloov lub log kawg lub ntsej muag | - Tshawb xyuas cov kab tuab txhua hli; - Tsis txhob tso roj rau ntawm qhov chaw sib txhuam; - Re- xyuas lub caij nplooj ntoos hlav preload txhua xyoo |
| Hydraulic lub tog raj kheej roj to(roj seepage ntawm piston pas nrig / connector) | 1. Kev puas tsuaj piston pas nrig foob; 2. xoob hydraulic txuas; 3. Xov puas ntawm kev sib txuas | 1. Hloov cov khoom siv foob (siv cov khoom qub); polish piston pas nrig yog khawb me ntsis; 2. Re-tighten sib koom nrog xov sealant; 3. Hloov cov connector puas; siv los tiv thaiv - txeeb rau xov | - Hloov cov ntsaws ruaj ruaj txhua 6 lub hlis; - Tshawb xyuas cov pob qij txha thaum taug kev txhua hnub |
| Limit hloov tsis ua hauj lwm(tsis muaj teeb liab sib cuam tshuam; qhia tsis tseeb tso tawm) | 1. Kev sib cuag tsis zoo vim corrosion; 2. Cov kab hluav taws xob puas tsuaj; 3. Misaligned hloov actuator | 1. Ntxuav cov neeg sib cuag; siv tshuaj tiv thaiv-corrosion roj; 2. Hloov cov xov hlau puas; xyuas IP65 tiv thaiv; 3. Re-align actuator kom ua kom ntseeg tau ntawm kev tso tawm tag nrho | - Hloov pauv txhua hli; - Siv cov ntaub thaiv npog rau kev teeb tsa sab nraum zoov |
| Suab nrov / kev vibration(sib tsoo / squealing thaum braking / tso tawm) | 1. Loos mounting bolts; 2. Kev hnav tsis sib xws; 3. Log kawg lub ntsej muag deformation; 4. Disc caij nplooj ntoos hlav resonance | 1. Tighten M16 bolts to 80-100 N·m; 2. Replace unevenly worn lining; 3. Check wheel runout; reface if >0.1 hli; 4. Ntxiv damping washer rau lub caij nplooj ntoos hlav chamber | - Tighten bolts peb lub hlis twg; - Kos lub log kawg lub ntsej muag txhua xyoo |
| Hnav khaub ncaws ceev heev(Lub voj voog hloov<3 months) | 1. Ceev nrooj braking; 2. Hauv ob sab phlu- log clearance me me heev (txuas); 3. Cov ntaub thaiv kab mob (xuab zeb / ntsev pos huab) | 1. Txhim kho kev tswj xyuas kom zoo kom txo qis kev sib tsoo thaum muaj xwm ceev; 2. Kho qhov clearance mus rau 0.5-1 mm; 3. Ntxuav hauv ob sab phlu tsis tu ncua; siv cov ntaub thaiv corrosion-resistant hauv cov ntug hiav txwv | - Siv S3-60% kev ua haujlwm; - Tsis txhob nres ib nrab ncua ntev |
| Kev tso tawm qeeb(Kev sib cais qeeb qeeb tom qab kev thov siab) | 1. Hydraulic system nrog cua; 2. Ib qho - txoj kev throttle valve misadjusted; 3. Thruster piston qeeb zog | 1. Cua los ntawm hydraulic Circuit Court (pib los ntawm lub tog raj kheej mus rau chaw nres tsheb); 2. Kho lub throttle valve rau 0.3-0.5 s tso lub sij hawm; 3. Ntxuav lub piston thiab lubricate lub tes tsho | - Ntshav system tom qab hloov roj; - Tshawb xyuas lub valve peb lub hlis twg |
Tshwj xeeb Fault: Phau Ntawv Tso Tawm Tsis Ua Haujlwm
Ua rau: Jammed phau ntawv tso tawm qib lossis tawg txuas txuas.
Kev daws: 1. Siv cov roj nkag mus rau qib pivot; 2. Txheeb xyuas qhov txuas txuas rau kev khoov; hloov yog puas; 3. Ntsuas phau ntawv tso tawm tom qab txhua qhov kev kho.
Cov tswv yim daws teeb meem tseem ceeb
Kev Txiav Txim Ua Ntej: Nco ntsoov xyuas hydraulic siab → txwv kev hloov pauv → kev sib txhuam hauv ob sab phlu ua ntej, vim cov no yog cov ntsiab lus tsis ua haujlwm ntau tshaj.
Interlock Safety: Tsis txhob hla kev txwv kev hloov pauv; xyuas kom lub crane tsis tuaj yeem taug kev tshwj tsis yog tias tus nres tau tso tawm tag nrho.
Qhov Tseeb: Siv cov ntsaws ruaj ruaj qub, hauv ob sab phlu, thiab disc springs kom tsis txhob muaj teeb meem kev sib raug zoo.
