sendzimir dov zeb
Lub koov ntawm Sendzimir dov zeb txais ib qho tseem ceeb casting thiab prestressing. Lub koov yog nruab nrog arc khiav los txhim kho cov menyuam txhawb nqa. Tag nrho cov txheej txheem nruab nrab yog tsau rau ntawm lub koov thav duab los ntawm kev ncua hydraulic lub tog raj kheej ntawm sab kis tau tus mob thiab sab ua haujlwm, thiab lub zog ncua kev kawm raug teem raws li qhov hnyav ntawm cov menyuam lub cev.
Lub ntsiab zoo ntawm Sendzimir 20-siab zeb:
1) Txoj kab uas hla ntawm txoj haujlwm yob yog me me, thiab tam sim no feem ntau dov mills siv cov yob ua haujlwm ntawm Φ63.5;
2) Cov txheej txheem rau cov menyuam muaj kev ruaj khov, thiab qhov teeb meem ntawm kev tsis ruaj khov ntawm cov menyuam tsis tau tshwm sim rau ntau xyoo;
3) Lub rigidity yog loj, feem ntau ncav cuag 4440 ~ 4900kN / hli, uas yog conducive rau kev txhim kho cov thickness raug;
4) Cov kev txwv sab saud ntawm dov siab yog qhov loj, feem ntau ncav cuag 7800 ~ 8000kN, thiab qhov txo qis ntawm qhov hla yog loj;
5) Vim tias cov menyuam sab nrauv txais cov kabmob, kev hloov kho yas yog hloov tau thiab yooj yim;
6) Lub axial txav ntawm cov menyuam nruab nrab tuaj yeem pom tau, uas muaj txiaj ntsig zoo rau sab siv txoj siv sia ntawm cov sawb hlau;
7) Los ntawm kev kho F thiab G rollers, qhov siab ntawm txoj kab dov tuaj yeem hloov kho tau yooj yim;
8) Cov roj rolling txias yog muab rau cua txias los ntawm cov deflector, uas muaj lubrication zoo thiab lubrication nyhuv;
9) Tsis muaj qhov txav ntawm lub thav duab tshwj tsis yog cov menyuam thiab cov ntawv qhia siv, uas yooj yim rau kev khiav lag luam thiab kev saib xyuas thiab kev lag luam txhim khu kev qha;
Qhov tsis zoo ntawm Sendzimir' s 20-siab txias dov zeb:
1) Qhov qhib me me tsis haum rau hnav thiab dov. Tsis tuaj yeem paub qhov hloov pauv tsis siv neeg yob, lub sijhawm tig ntev;
2) Cov yob tuaj yeem siv rau hauv ib qho me me, qhov tuab ntawm cov yob yuav tsum tau siv ua ke, lub yob cia yog loj, thiab kev tswj yob thiab siv tus nqi siab;
3) Siv lub nplhaib eccentric hloov kho, cov lus teb qeeb thiab tsis tshua muaj kev tswj xyuas qhov tseeb;
4) Muaj ob peb pawg tswj hwm txoj kev tswj hwm thiab tsis zoo ntawm pawg tswj hwm kev muaj peev xwm. Vim tag nrho cov qauv ntawm cov khib nyiab, kev tswj ncaj nraim tsis tuaj yeem ua tiav.
Thaum lub sijhawm hloov kho, ob lub bearings raug cuam tshuam rau tib lub sijhawm, kev sib kis ntawm cov menyuam txhawb nqa, cov menyuam thib ob nruab nrab, thiab thawj cov menyuam nruab nrab raug txo qis, thiab kev tswj kev muaj peev xwm txo qis heev. Nws yog ib qho nyuaj rau kev txheeb xyuas qhov kev hloov ntawm lub phaj zoo, tshwj xeeb tshaj yog tom qab 1/4 nthwv dej ntawm qhov tseeb dov phaj zoo li, nws tsis tuaj yeem tshem tawm tag nrho. Thawj cov menyuam nruab nrab muaj qee qhov taper, thiab thawj cov menyuam nruab nrab txav axially nyob rau hauv qhov kev txiav txim ntawm lub laub-rub hydraulic lub tog raj kheej. Xav txog lub xeev ntawm kev thawb-rub, lub phaj tswj tsuas yog koom nrog thaum lub dov ceev nce mus txog 100 m / min. Vim qhov kev txwv ntawm kev txav ceev, thaum lub taub hau thiab tus Tsov tus tw dov ceev tsawg dua 100m / min, lub phaj zoo tswj muaj peev xwm cuam tshuam zoo heev, thiab cov cuab yeej ua haujlwm tseem ceeb yuav tsum muaj kev ua haujlwm siab.
