Ib zaug kuv tau xam phaj tus kws tshaj lij hauv daim teb no uas tau qhia qee qhov kev nkag siab rau kuv. Kuv tau sau cov ntsiab lus tseem ceeb hauv qab no thiab xav qhia rau koj tam sim no.
Nws tau hais tias: "Kuv tau siv sijhawm 12 xyoos ua haujlwm ntawm- qhov chaw tu lub tshuab plastering. Kuv tau ua haujlwm ntawm 37 qhov chaw tsim kho thiab kho 218 lub tshuab ntawm ntau yam qauv-tab sis tiag tiag, kuv tsis tau kho tshuab; Kuv tau kho tib neeg yuam kev. Cov lus hais hauv qab no tau sau rau ntawm 3:00 AM tsis tau rov qab los ntawm cov hlau, tab sis kuv tab tom kho cov tshuab tsis tau. Kab lus txhua lo lus yog qhov tseeb tiag."
I. Tshuab Installation? Thawj Tshawb xyuas lub Foundation; Ces Kos Koj Tes
Tsis txhob maj nrawm kom nruj cov bolts. Thaum twg kuv ua tus saib xyuas lub tshuab tshiab, thawj qhov uas kuv ua yog siv cov kav dej laser los ua ob txoj kab siv: ib qho khiav lengthwise raws kab tseem ceeb, thiab lwm qhov khiav diagonally hla lub hauv paus phaj. Puas yog qhov kev sib dhos yuam kev ntau dua 1.5 hli? Nres tam sim ntawd. Kho lub hauv paus shims ncaj qha-thiab tsis txhob cia siab rau "xav" kom kaw lawv; siv lub calibrated torque ciaj ntswj kom nruj txhua tus ntsia liaj qhov rooj ntawm tus kheej raws li cov neeg tsim khoom specifications (feem ntau 185 ± 5 N·m). Xyoo tas los, ntawm ib qhov project hauv Hefei, cov neeg ua haujlwm- sim txuag lub sijhawm- ntaus lub bolts ob peb lub nrawm *clacks * nrog lub pneumatic cuam tshuam wrench. Qhov tshwm sim? Tom qab tsuas yog peb hnub ntawm kev ua haujlwm, cov ntawv qhia kev tsheb ciav hlau tau pom cov cim qhia ntawm qhov tsis sib xws (0.2 hli sib txawv), thiab nws siv ob hnub tag nrho ntawm kev rov ua haujlwm los rhuav tshem thiab rov nruab lub tshuab kom zoo.
Raws li rau ob qhov kev hloov kho li qub ntawm cov hydraulic outriggers, tsis txhob kho lawv zoo li cov ntsia hlau zoo tib yam. Kuv ib txwm nqa lub ntsuas siab nrog kuv (nrog 0-10 MPa ntau) los teeb tsa lub siab rau 6.2 ± 0.3 MPa. Daim duab tshwj xeeb no sawv cev rau "qhov chaw qab zib"- qhov sib npaug zoo tshaj plaws ntawm kev pabcuam lub neej ntawm cov ntsaws ruaj ruaj piston thiab cov qauv rigidity ntawm kev txhawb nqa. Teeb nws dhau xoob? Lub vibration zaus ntawm plastering hniav yuav dhia mus rau 8.7 Hz, ua rau tam sim ntawd ripples tshwm nyob rau saum npoo ntawm cov ntaub ntawv mortar. Teem nruj heev? Koj yuav pom pom micro-deformation ntawm kab flange welds- pom tseeb tias qhov sib koom ua ke yuav tawg hauv peb lub hlis.
Ua ntej txuas cov khoom siv hluav taws xob, siv lub ntsuas theem ua ntu zus los ua qhov ntsuas ceev. Puas yog cov theem ib nrab thim rov qab? Yog tias muaj, qhov kub ntawm lub cev muaj zog bearings yuav skyrocket mus rau 92℃(raws li kev txheeb xyuas los ntawm lub koob yees duab thermal infrared), thiab cov bearings yuav ntes tau tag nrho tom qab tsuas yog peb zaug sib law liag ntawm kev ua haujlwm. Qhov teeb meem loj tshaj plaws uas kuv tau pom muaj feem xyuam nrog tus thawj coj uas hais rau nws tus kws hluav taws xob "tsuas yog tis nws raws li kev paub dhau los." Qhov tshwm sim? Lub V-theem thiab W-theem xov hlau tau xa rov qab mus rau hauv qhov hloov pauv zaus tsav (VFD). Kaum xya vib nas this tom qab fais fab tuag, lub IGBT module nyob rau hauv lub tsav ntsoos tawm, sau cov huab cua nrog acrid tsis hnov tsw ntawm burnt electronics.
II. Koj sau dab tsi koj tseb: Lub Mortar's Temperament Reflects Nws Pub
Finer mortar tsis tas yuav zoo dua. Ntawm peb qhov chaw tsim kho, peb ua haujlwm ntawm peb tus kheej qhov chaw tshuaj ntsuam xyuas, qhov uas peb nruj me ntsis txwv cov khoom siv los ntawm 5mm square-qhov sieve; Txawm li cas los xij, peb hais kom khaws 3% mus rau 5% quartz xuab zeb nrog cov nplej loj ntawm 1.2mm thiab 2.5mm. Cov nplej no ua haujlwm zoo li cov kabmob me me, ua rau "micro-lubrication txheej" ntawm ntug ntawm cov hniav scraper, yog li txo tus nqi ntawm cov hniav hnav. Siv dej xuab zeb nkaus xwb? Koj yuav txiav cov scraper lub neej kev pabcuam los ntawm 40%.
Tsis txhob sau lub hopper rau 80% muaj peev xwm; uas tsuas yog qhov siab tshaj plaws theoretical xwb. Hauv kev xyaum, kuv txwv cov qib sau rau 72%- tawm ntawm 8% tsis pub rau lub mortar rau "ua pa." Vim li cas? Vim hais tias cov mortar tau nthuav dav me ntsis thaum lub sij hawm siv cov txheej txheem -tshwj xeeb tshaj yog nyob rau lub caij ntuj sov thaum kub tshaj 32 degree, nyob rau hauv lub point qhov expansion yuav ncav cuag 3.8%. Yog nws overflows? Nws yuav tig mus rau hauv cov lus qhia rails thiab nkag mus rau hauv qhov txwv hloov vaj tse; los ntawm hnub tom qab, koj yuav raug yuam kom hloov tag nrho cov kab mob stroke tswj module.
Ua ntej yuav hloov lub tshuab, peb kauj ruam yuav tsum tau: tso hydraulic siab → txiav fais fab → manually retract lub outrigger locking pins. Lub hli tas los hauv Xuzhou, tus kws tshaj lij - nrhiav cov kauj ruam no nyuaj heev - tau sim thawb lub tshuab mus rau txoj haujlwm tshiab thaum nws tseem nyob hauv hydraulic siab. Qhov tshwm sim? Lub hauv paus kab pheeb ces kaum deformed, thiab hydraulic lub tog raj kheej piston pas nrig khoov los ntawm 0.7 hli. Kev kho lub Hoobkas tom ntej- cuam tshuam ncaj qha thiab chrome plating- tuaj nrog tus nqi hais txog 1.3 npaug ntau dua tus nqi ntawm lub hom phiaj - lub tog raj kheej tshiab.
III. Kev ntxuav tsis yog "Tso nws" xwb; Nws yog "Kev Sib Tw Tawm Tsam Sijhawm"
Thaum lub sijhawm txiav tawm - lub tswb nrov, txhua tus neeg tawm mus, tab sis kuv nyob tom qab. Qhov no yog vim lub qhov rais ntawm lub cib fim-los ntawm lub mortar thawj zaug teem rau nws zaum kawg teeb - kav ib tug tsuas yog 22 feeb (xav tias qhov kub ntawm ambient ntawm 25℃). Kuv siv lub siab - lub dav hlau dej siab (siab tsawg dua lossis sib npaug li 8 MPa) txhawm rau tshem tawm cov lus qhia, tab sis lub nozzle yuav tsum tau khaws cia ntawm qhov deb tsawg kawg 35 cm ntawm cov menyuam. Yog tias nyob ze dhau lawm, cov dej tsis zoo yuav nkag mus rau tus lej encoder cov kabmob, ua rau suav cov txheej txheem ua tsis tiav hauv ib lub lis piam.
Ntxuav plua plav los ntawm lub txee hluav taws xob? Kuv yeej tsis siv daim ntaub txheem. Hloov chaw, kuv siv cov ntaub ntawv kho mob- qib tsis yog- woven npuag dampened nrog 99.8% anhydrous ethanol, so hauv ib qho kev taw qhia kom paub tseeb tias tsis muaj lint nyob hauv qab. Muaj ib zaug, ib tug neeg ua haujlwm tau siv daim ntawv phuam so hauv PLC module; cov ntawv fibers tau nkag mus rau hauv lub dab dej kub, ua rau CPU ua kom kub dhau thiab ua rau nws lub moos ceev. Yog li ntawd, lub thickness yuam kev nyob rau hauv daim ntawv thov mortar dhia mus rau ib tug unacceptable ± 5mm.
Ua lub voj voog tsis muaj -load nqa? Nws tsis yog ib qho teeb meem ntawm kev khiav nws "nce thiab nqis ob peb zaug." Kuv teeb tsa cov kab ke raws li hauv qab no: Ascend → Pause rau 2 vib nas this → nqis → Pause rau 2 vib nas this → Ascend dua → Pause rau 2 vib nas this → nqis dua. Qhov no suav nrog tag nrho ntawm rau lub voj voog. Lub hom phiaj ntawm qhov no yog tso cai rau cov dej seem seem kom evaporate los ntawm cov cua sov uas tsim los ntawm cov lus tsa suab reciprocating- cov dej uas nyob rau hauv lub microscopic pores ntawm cov lus qhia rails tsuas yog tsis tuaj yeem raug tshem tawm tag nrho los ntawm cov kua dej zoo li qub.
IV. Kev tu tsis yog tsuas yog hais txog "Ua raws sijhawm"; Nws yog hais txog "Kev nkag siab tias lub tshuab qhia koj li cas"
Kuv lub cev tshuaj xyuas cov hlua hlau txhua hnub. Kuv tsis yog tab tom nrhiav kev tawg strands; Kuv siv kuv tus ntiv tes txhuam hla hla qhov khoob ntawm txoj hlua hlua. Yog hais tias kuv tus ntiv tes khawb tawm ib qho grey, hmoov av seem, nws qhia tau hais tias cov lubricant sab hauv tau qhuav lawm, thiab lubrication yuav tsum tau siv hnub ntawd. Xyoo tas los, ntawm qhov chaw tsim kho hauv Nantong, lawv tsis muaj tus cwj pwm no; ib txoj hlua ib leeg tau khaws cia rau hauv kev pabcuam rau 117 hnub kom txog rau thaum tus naj npawb ntawm cov hlua tawg dheev skyrocketed los ntawm peb mus rau kaum cuaj. Nws snapped thaum lub sijhawm ua haujlwm hoisting, smashing thiab khoov tag nrho cov lus qhia rail.
Kuv mloog lub vibrator peb zaug thaum txhua qhov kev hloov pauv: thaum lub sijhawm pib, thaum nruab nrab ntawm kev ua haujlwm, thiab tsib vib nas this ua ntej kaw. Lub suab profile ib txwm yog "Buzz-Hum-Hum"; ib qho profile txawv txav yog "Buzz-Click-Hum." Qhov txawv "nias" suab yog ib qho qhia tau hais tias qhov kev tshem tawm hauv cov kabmob eccentric tau dhau qhov kev txwv ntawm 0.08 hli. Thaum lub sij hawm koj pib hnov ib tug ceev "nias-nias-nias," lub bearing twb tawg lawm.
Kuv ua qhov kev sim ua ntu zus ntawm cov roj hydraulic. Kuv tsis tsuas txiav txim nws los ntawm xim; Hloov chaw, kuv siv lub txee qhov khoom txav tau yooj yim (ua raws li ISO 4406 tus qauv). Sai li qhov kev huv huv tshaj li 18/16/13 qhov pib, kuv tam sim ntawd hloov cov roj thiab ntxuav lub lim lim. Muaj ib lub sijhawm, tus neeg siv khoom tsis kam them rau kev hloov pauv thiab hais kom txuas ntxiv siv cov roj kom txog thaum nws cov pa paug mus txog 22/20/17; Qhov tshwm sim yog ib tug seized servo valve spool, rendering tag nrho hydraulic system irreparable thiab haum tsuas yog rau cov seem seem.
V. Tej yam "Cov Kab Liab" tuaj yeem ua rau koj lub neej raug nqi tiag
hnov ib lub suab txawv txawv? Cov lus teb tsis yog "cia peb khiav nws ob peb zaug ntxiv kom pom tias muaj dab tsi tshwm sim"; nws yog tam sim ntawd txiav lub hwj chim, affix ib daim ntawv ceeb toom, thiab kaw cov khoom siv. Kuv ib zaug tau pom ib tug kws tshaj lij qub tub rog-"tus tswv qub" ntawm kev lag luam- tshaj tawm tias, "Kuv tsuas muaj ob phab ntsa sab laug kom tiav," thiab tawv ncauj thawb mus rau qhov kawg txawm tias lub gearbox emitting ib tug siab - suab shriek. Qhov tshwm sim? Lub gearbox lub input ncej sheared huv si los ntawm, thiab cov ya ya los ntawm cov pob txha hlais tawm ib nrab ntawm nws tus ntiv tes me ntsis.
Xav txog kev nthuav dav kab qhov siab? Cov duab kos duab qhia txog qhov siab tshaj plaws ntawm 12.8 meters. Yog tias koj twv kom thawb qhov kev txwv mus rau 13.2 meters, qhov tshwm sim hauv qhov chaw ntawm lub ntiajteb txawj nqus yuav ua txhaum txoj cai tseem ceeb ntawm kev nyab xeeb (kev ntsuas tau qhia qhov sib txawv no nce mus txog 4.7 degrees). Xyoo tas los, ntawm ib qhov project hauv Changsha, peb tau ua txhua yam raws nraim li ntawd; thaum cua ceev ntaus Force 6, tag nrho chav tsev swayed los ntawm ± 11 cm- txaus rau cov hniav scraper mus rau gouge kauv qauv ncaj qha mus rau hauv lub phab ntsa nto.
Cia? Tsis txhob poob rau cov dab neeg hais tias "tsuas yog pov ib lub tarp tshaj nws yuav ua." Kuv cov kev cai yog nruj: lub hauv paus yuav tsum tau cushioned nrog ib tug 10 cm - tuab ua npuas ncauj board topped nrog ib tug reflective aluminium foil membrane (rau kev tiv thaiv ya raws), thiab ib tug los nag vaj tse yuav tsum tau tsa saum taub hau (nrog ib tug nqes hav ntawm yam tsawg kawg nkaus 15 degree), kom lub eaves ncav cuag yam tsawg 80 cm tshaj lub tshuab lub cev. Yog tias sab laug raug nyob rau hauv qhov chaw ntub dej tsuas yog 48 teev, cov kab tooj liab ntawm PLC mainboard yuav pib oxidize thiab tig dub.
-Tsis muaj qhov no sau rau hauv phau ntawv; cov no yog cov lus qhia uas kuv tau sau rau hauv lub cim xeeb los ntawm tus nqi ntawm kuv lub sijhawm, kuv cov nyiaj, thiab kuv lub hws. Ua raws li cov kauj ruam no, thiab koj lub tshuab yuav mus tsib xyoos yam tsis xav tau kev kho dua tshiab; txiav cov ces kaum, txawm li cas los xij, thiab lwm zaus koj hu rau kuv -zoo li ob tag kis sawv ntxov- koj yuav tau npog hauv cov hmoov av cement, hais tias: "Tus Tswv, nws yuav tsis txav mus."
