YW-E200/E50A yog ob- kauj ruam electro-hydraulic nruas nres los ntawm YW-E series, kev koom ua ke nrog E50A electro-hydraulic thruster raws li nws cov ntsiab lus tsav. Nws nta 200 hli nruas txoj kab uas hla, dual- theem nres nres torque tso zis (tsawg- nrawm nrawm nrawm + ceev ceev siab- torque braking), thiab ib txwm kaw kev nyab xeeb tsim. Optimized rau cov cuab yeej uas yuav tsum tau tswj kev ceev nrawm thiab txhim khu kev qha thaum muaj xwm txheej ceev, nws yog dav siv hauv cranes, hoists, conveyors, thiab metallurgical auxiliary machinery. Hauv qab no yog nws cov ntsiab lus tseem ceeb, txoj hauv kev ua haujlwm, cov yam ntxwv tseem ceeb, kev teeb tsa tshwj xeeb, thiab cov ntawv thov raug:

2. Txoj Cai Ua Haujlwm
Lub nres paub txog ob - kauj ruam braking los ntawm E50A thruster lub dual - lub zog tso zis thiab tus nres lub dual - lub caij nplooj ntoos hlav pab pawg tsim, raws li ib txwm kaw logic:
2.1 Nres Tso Tawm (Power-Ntawm theem)
Thaum cov cuab yeej ua haujlwm khiav, E50A thruster yog lub zog thiab tso tawm thawj lub siab hydraulic (8-10 MPa). Lub laub pas nrig txuas mus rau linearly, compressing thawj -stage brakes springs, thiab cov brake khau cais tawm ntawm lub nruas (clearance: 0.3–0.5 mm) kom tiav tso tawm.
2.2 Ob-Txoj Kev Sib Txuas Sib Txuas
Kauj ruam 1 (Precision Braking): Thaum cov cuab yeej xav tau qeeb qeeb, lub thruster txo hydraulic siab mus rau 4-6 MPa. Thawj -theem springs rebound ib feem, thawb lub brake khau kom maj mam clamp lub nruas, tsim 630-1000 N·m torque kom du nrawm.
Kauj ruam 2 (Emergency Braking): Rau qhov chaw nres tsheb thaum muaj xwm txheej ceev lossis kev kaw haujlwm thauj khoom, lub thruster yog de-energized. Hydraulic siab yog tag nrho relieved, thiab ob qho tib si thawj / thib ob - theem springs rebound kiag li. Lub brake khau khi lub nruas kom nruj, tawm 1600-2500 N· siab torque kom nres cov cuab yeej sai.
Fail -Safe Braking: Nyob rau hauv cov ntaub ntawv ntawm lub hwj chim tsis ua hauj lwm los yog thruster malfunction, ob lub caij nplooj ntoos hlav pawg ua ib txhij mus cuag thaum muaj xwm ceev braking nyob rau hauv tsawg dua los yog sib npaug zos rau 0.4 vib nas this, tiv thaiv cov khoom khiav.
2.3 Kev Nyab Xeeb Kev Nyab Xeeb
Lub E50A thruster yog nruab nrog F-chav tsev rwb thaiv tsev thiab thermal tiv thaiv (ua rau ntawm 155 degree) kom tsis txhob muaj lub cev muaj zog.
Ib qho ua tau - nyob rau hauv lub siab nyem valve (max siab tsawg dua los yog sib npaug rau 18 MPa) tiv thaiv lub hydraulic system los ntawm overpressure; tsis siv neeg hnav compensator tswj kev ruaj ntseg nres clearance.
