2. Txoj Cai Ua Haujlwm
Lub nres siv lub "ib txwm kaw + tawg- tiv thaiv electro- hydraulic tsav" tsim, nrog rau BEd121/6 thruster muab lub zog. Nws txoj haujlwm yog nyob ntawm kev sib koom tes ntawm hydraulic thrust thiab nres lub caij nplooj ntoos hlav quab yuam, muab faib ua peb theem tseem ceeb:
2.1 Nres Tso Tawm (Power-Ntawm theem)
Thaum cov khoom siv tswv tsev yuav tsum tau ua haujlwm, BEd121/6 tawg - tiv thaiv thruster yog energized. Nws ua tau - nyob rau hauv tawg- pov thawj lub cev muaj zog tsav lub twj tso kua mis hydraulic los tsim 12-16 MPa hydraulic siab, thawb lub thruster lub laub pas nrig kom txuas mus rau linearly.
Lub laub qws xa cov quab yuam mus rau tus nres lub zog mechanism, compressing lub siab - nro lub caij nplooj ntoos hlav nres (60Si2MnA alloy steel) thiab tsav tsheb ob lub nres khau kom cais tawm sab nraud ntawm lub nruas.
Ib tug 0.3-0.5 hli uniform clearance yog tsim nyob rau hauv lub brake hauv ob sab phlu (asbestos-dawb resin-raws li composite, hnav-resistant thiab siab- kub resistant) thiab lub nruas nres, tso cai rau lub nruas tig ywj siab nrog cov cuab yeej rotating action.completing {{6}
2.2 Kev sib koom ua ke braking (Power-Off theem)
Thaum cov cuab yeej nres lossis muaj xwm txheej ceev, lub zog thruster yog de{0}}energized. Lub hydraulic system relieves siab, thiab lub thruster lub laub pas nrig retracts nyob rau hauv qhov kev txiav txim ntawm nws sab hauv rov qab caij nplooj ntoos hlav.
Lub caij nplooj ntoos hlav nres tau nrawm nrawm, thawb cov khau khau kom clamp sab hauv mus rau lub nruas nres. Kev sib txhuam ntawm cov hauv ob sab phlu thiab lub nruas tsim 1200 N·m braking torque, decelerating cov cuab yeej kom txog thaum nws nres thiab tswj lub xeev xauv.
Nyob rau hauv cov ntaub ntawv ntawm tam sim no lub hwj chim tsis ua hauj lwm los yog thruster malfunction, lub feem ntau kaw tsim kom lub nres nres, tiv thaiv cov cuab yeej khiav mus rau hauv ib puag ncig txaus ntshai.
2.3 Cov txheej txheem tiv thaiv kev nyab xeeb
Overload & Overheat tiv thaiv: Lub BEd121/6 thruster yog nruab nrog lub thermal tiv thaiv (F-chav tsev rwb thaiv tsev) uas txiav tawm lub zog thaum lub cev muaj zog kub tshaj 155 degree. Lub nres ua haujlwm - nyob rau hauv nyem valve tiv thaiv hydraulic system overpressure, tsis txhob cuam tshuam cov khoom puas.
Explosion-Proof Safety: Tag nrho cov khoom siv hluav taws xob (thruster lub cev muaj zog, txoj hauj lwm sensor) txais cov ntaub thaiv npog uas muaj qhov tawg me me (tsawg dua los yog sib npaug li 0.2 hli), tiv thaiv cov hluav taws xob sab hauv los ntawm igniting lwm cov nplaim hluav taws xob lossis plua plav. Kev tawg-cov pov thawj cable caj pas kaw cov hluav taws xob sib txuas los thaiv cov pa roj / plua plav nkag.
Hnav Khaub Ncaws: Ib qho ua tau - nyob rau hauv tsis siv neeg hnav adjuster them nyiaj txog li 10 hli ntawm cov ntaub hauv ob sab phlu, tuav lub braking torque thiab clearance yam tsis muaj phau ntawv calibration.
Interlock Control: Kev tawg- pov thawj txoj hauj lwm sensors tso tawm "tso tawm" thiab "sib koom" cov cim, ua kom muaj kev cuam tshuam nrog cov khoom siv tswv cuab- kom ntseeg tau tias tus tswv tuaj yeem pib thaum lub nres nres tag nrho, thiab nres tam sim ntawd thaum lub nres nres.
