Kauj Ruam 1: Kev Ntsuas Ua Ntej thiab Kev Txiav Txim Siab
Pib lub cav thiab tso cai rau lub compressor ua haujlwm ib txwm, saib xyuas qhov ntsuas qhov ntsuas qhov hloov pauv. Sau lub compressor qhov pib siab (qis txwv) thiab nres siab (sab sauv txwv). Yog tias qhov ntsuas siab tsawg dua 0.2 MPa (kwv yees li 29 psi), lossis yog tias lub siab poob qis dua 0.1 MPa hauv 30 vib nas this tom qab nres, feem ntau tuaj yeem ua txhaum. Ib txhij, mloog lub compressor pib-stop voj voog. Yog tias lub voj voog qis dua 2 feeb (feem ntau 5-10 feeb), thiab tsis muaj qhov xav tau huab cua, qhov kev ua txhaum ntau zaus tuaj yeem lees paub.
Kauj ruam 2: Cua System Leak Troubleshooting
1. Kev Npaj Kev Nyab Xeeb: Chaw nres tsheb lossis cov khoom siv rau ntawm qhov chaw, ruaj ntseg nrog lub log chocks, tso cov khoom seem hauv lub siab, thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
2. Kev Ntsuas Siab: Pib lub cav thiab tso cai rau lub compressor twj tso kua mis mus rau 550-690 kPa (80-100 psi), ces tua lub cav.
3. Tiv thaiv kom tsis muaj dej: Siv cov dej xab npum rau qhov chaw uas xav tias xau thiab saib cov npuas. Ua tib zoo saib xyuas cov compressor gaskets, cov yeeb nkab txuas, cua tank li qub, cua tshuab ziab khaub ncaws, thiab cov kab nres. Rau qhov chaw uas tsis yooj yim rau kev soj ntsuam ncaj qha, lub suab txoj kev siv tau los pab rau kev txiav txim siab; ib tug xau yuav emit ib tug txawv airflow suab.
Kauj Ruam 3: Kev Ntsuam Xyuas Kev Ruaj Ntseg Hauv Cheeb Tsam
1. Kev Tshuaj Ntsuam Xyuas Kev Ruaj Ntseg: Disassemble lub siab regulator teeb liab yeeb nkab thiab xyuas cov blockages; manually nias lub siab regulator valve core los soj ntsuam seb lub zog yog hloov tau thiab seb puas muaj ib qho jamming; txheeb xyuas qhov ntsuas qhov ntsuas qhov ntsuas kom ntseeg tau tias nws ua tau raws li cov kev cai ntawm cov khoom siv phau ntawv (feem ntau, qhov pib siab yog 450-500 kPa, thiab lub siab nres yog 750-800 kPa);
2. Unloading Valve Inspection: Tshem tawm lub unloading valve lub cev thiab xyuas seb lub sab hauv O-rings thiab rectangular seals puas muaj hnub nyoog los yog puas, seb lub caij nplooj ntoos hlav nro txaus, thiab seb lub valve core sealing nto yog hnav los yog muaj carbon deposits;
3. Pressure Gauge Calibration: Calibrate lub siab ntsuas qhov qub ntawm cov cuab yeej siv tus qauv ntsuas ntsuas kom tshem tawm cov teeb meem kev ntsuas siab tsis raug.
Kauj Ruam 4: Compressor Lub Cev thiab Kev Tshuaj Xyuas Tom Qab Kev Kho Mob
1. Kev nkag mus thiab cov pa tawm: Xyuas seb lub tshuab cua compressor cua lim puas tau txhaws, thiab yog tias cov kav dej nkag tau puas lossis deformed; disassemble lub tso pa yeeb nkab thiab xyuas cov pa roj carbon buildup. Yog hais tias cov pa roj carbon buildup thickness tshaj 1 hli, nws yuav tsum tau muab ntxuav los yog hloov tam sim ntawd.
2. Cov Cheebtsam Tom Qab Kev Kho Mob: Tshawb xyuas lub thawv cua tshuab desiccant. Yog hais tias nws pom cov tsos mob ntawm caking los yog discoloration (feem ntau yog xiav, liab liab thaum tsis zoo), nws yuav tsum tau hloov tam sim ntawd; disassemble lub lim thiab xyuas seb lub tshuab lim yog txhaws thiab yog tias cov kua dej solenoid valve ua haujlwm zoo.
3. Compressor Internal Inspection: Yog hais tias cov kev ntsuam xyuas saum toj no yog tag nrho cov qub, disassemble lub compressor thiab xyuas cov khoom noj thiab cov pa valve seals, lub piston -lub tog raj kheej phab ntsa coj clearance, thiab cov roj rov qab kab rau blockages.
Cov ntsiab lus daws teeb meem
(I) Troubleshooting Air System Leaks
1. Kev Kho Foob: Yog tias muaj kev laus lossis kev puas tsuaj rau gaskets lossis O-rings pom, hloov lawv nrog tib tus qauv. Ua ntej kev teeb tsa, siv qhov tsim nyog ntawm qhov siab - kub roj rau lub sealing nto kom ntseeg tau tias lub foob zoo.
2. Kev Kho Cov Yeeb Nkab: Rau cov kav dej xoob xoob, rov ua kom rov qab mus rau lub zog uas tau teev tseg hauv cov khoom siv (feem ntau, lub zog rau cov yeeb nkab fittings yog 14 N·m, kwv yees li 10 ft-lb). Rau cov hoses lossis cov kav dej puas lawm, hloov tam sim ntawd, thiab ua qhov kev sim siab tom qab hloov.
3. Kev Kho Valve: Yog tias cov li qub tau xau, disassemble thiab ntxuav lub valve core sealing nto. Yog tias hnav hnyav, hloov tag nrho lub valve.
(II) Kev Kho Cov Khoom Siv Hluav Taws Xob Cov Khoom Uas Tsis Zoo
1. Pressure Regulator Handling: Yog tias lub teeb liab yeeb nkab raug thaiv, ntxuav nws nrog cua compressed; Yog hais tias lub valve core yog daig, tshuaj tsuag lub caij nplooj ntoos hlav phaj thiab tiv tauj nrog lub tshuab ntxhua khaub ncaws xws li WD-40, thiab nias dua 20-30 zaug kom ntseeg tau tias kev ua haujlwm du thiab txo kev tiv thaiv qis dua 0.1Ω; Yog hais tias tus nqi teev yog tawm, calibrate lub siab ntau yam los ntawm kev kho cov ntsia hlau, thiab pib qhov kev ntsuam xyuas tom qab calibration los xyuas kom meej qhov pib thiab nres thaum lub siab mus txog lub teeb nqi;
2. Unloading Valve Kho: Hloov cov ntsaws ruaj ruaj thiab qaug zog, ntxuav cov pa roj carbon deposits nyob rau hauv lub valve lub cev, thiab xyuas kom meej tias lub positioning claws ntawm lub unloading valve cover yog raug embedded nyob rau hauv lub slots ntawm lub valve lub rooj zaum thaum lub installation kom tsis txhob installation deviations;
3. Kev Hloov Siab Siab: Yog tias lub ntsuas ntsuas qhov ua yuam kev, hloov nws ncaj qha nrog lub ntsuas ntsuas siab uas ua tau raws li qhov yuav tsum tau ua kom ntseeg tau tias qhov ntsuas siab raug.
(III) Kev daws teeb meem Compressor Lub Cev Faults
1. Kev tu huv huv huv huv huv huv huv huv huv huv: Hloov cov lim cua huv hab huv huv huv ntawm cov yeeb nkab; Hloov cov pa roj carbon ntau- tso cov kav dej tso tawm, thiab xyuas cov turbocharger rau cov roj xau kom tsis txhob muaj roj nkag mus rau hauv cov kav dej thiab ua kom cov pa roj carbon ntau ntxiv;
2. Kev Kho Valve: Sib tsoo qhov sib khi ntawm cov khoom siv thiab cov pa tawm; Yog tias hnav ntau dhau, hloov tag nrho lub valve los ua kom lub valve sealing zoo;
3. Kev Kho Cov Khoom Siv Hauv Tsev: Yog tias cov piston thiab piston rings hnav dhau qhov kev txwv, yuav tsum muaj kev hloov kho loj lossis hloov tag nrho cov compressor sib dhos; huv si clogged roj rov kab los xyuas kom meej cov roj zoo thiab tiv thaiv compressor overheating.
(IV) Kev ua kom zoo ntawm Kev Kho Mob Tom Qab thiab Kev Pabcuam
1. Hloov Cov Khoom Siv Tom Qab Kev Kho Mob: Hloov lub thawv cua tshuab ziab khaub ncaws ua tsis tiav thiab cov lim lim lim; kho lossis hloov lub tshuab ziab khaub ncaws hauv lub tshuab ziab khaub ncaws, kho cov evaporator kub, thiab tiv thaiv dej khov;
2. Kev ua kom zoo ntawm lub tank cua: Yog tias cov cuab yeej muaj teeb meem nrog kev siv huab cua ntau dhau tam sim ntawd, lub tank cua ua raws li SAE J10 thiab FMVSS121 cov qauv tuaj yeem muab ntxiv los ua kom lub ntim thiab ruaj khov;
3. Idle Speed Adjustment: Yog tias lub cav tsis ua haujlwm ceev tau teeb tsa qis dhau, txheeb xyuas thiab kho nws raws li tus qauv tus nqi (rau cov tshuab hluav taws xob tswj hluav taws xob, xa mus rau cov khoom siv phau ntawv) kom paub meej tias lub compressor tau txais lub zog tsav txaus.
