Siab -Nov Trawl Qhov Rooj Tsim los ua kom muaj txiaj ntsig zoo
Trawl qhov rooj, tseem hu ua otter boards, yog ib qho tseem ceeb ntawm lub tshuab trawl. Lawv lub luag haujlwm tseem ceeb yog tsim kom muaj hydrodynamic nqa thiab tswj qhov yuav tsum tau qhib kab rov tav ntawm ob sab ntawm lub trawl net thaum lub sij hawm towing.
Rau kev lag luam trawling, qhov kev ua tau zoo ntawm lub qhov rooj trawl ncaj qha cuam tshuam rau kev sib kis, cab kuj, kev ruaj ntseg thiab kev ua haujlwm tag nrho. Lub qhov rooj zoo-tsim lub qhov rooj yuav tsum tsim kom muaj kev sib kis txaus thaum tswj hwm hydrodynamic rub thiab tuav tus cwj pwm ruaj khov nyob rau hauv kev hloov tsheb thauj khoom. Kev tshawb fawb ntawm otter-board hydrodynamics tau qhia tias nqa- mus rau- rub kev ua tau zoo yog ib qho ntawm qhov tseem ceeb hauv trawl - qhov rooj tsim.
Optimized Hydrodynamic Performance
Peb lub qhov rooj trawl yog tsim nyob ib ncig ntawm qhov sib npaug ntawmnqa, luag thiab stability, es tsis yog tsuas yog nce qhov chaw saum npoo av lossis qhov hnyav ntawm lub qhov rooj.
Kev ua haujlwm geometry ntawm lub rooj tsavxwm otter-nrog rau nws qhov profile, nam piv, camber, deflectors thiab cov qauv kev teeb tsa- cuam tshuam rau kev nqa tawm hauv cov dej ntws. Kev tsim hydrodynamic tsim nyog tso cai rau lub qhov rooj los tsim kom muaj kev sib kis ntawm lub zog txaus yam tsis muaj kev tsim kho tsis tsim nyog.
Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov nkoj nuv ntses ua lag luam, qhov twg ntau dhau rub ua rau muaj kev thauj mus los thiab tuaj yeem txo qis kev ua haujlwm. Cov kev tshawb fawb ntawm txawv otter- cov qauv tsim qauv tau pom tias kev txhim kho hauv nqa- mus rau - tus lej rub tuaj yeem ua rau muaj kev sib kis tau zoo dua thiab qis dua.
Stable Net Qhib Thaum Towing
Lub hom phiaj tseem ceeb ntawm lub qhov rooj trawl yog tswj qhov yuav tsum tau uakab rov tav kis ntawm lub qhov ncauj trawl.
Lub qhov rooj trawl ruaj khov pab kom ob lub qhov rooj ntawm qhov chaw ua haujlwm nyob deb thaum lub nkoj tab tom nqa. Lub qhov rooj tseem yuav tsum tswj tus cwj pwm uas xav tau thaum rub nrawm, qhov tob, dej hiav txwv lossis lub kaum sab xis ntawm kev tawm tsam.
Rau hauv qab trawling, kev sib raug zoo ntawm lub qhov rooj thiab seabed yog qhov tseem ceeb tshwj xeeb. Qhov rooj geometry, qhov hnyav faib thiab cov khoom siv qis tuaj yeem cuam tshuam rau kev sib kis thiab kev sib cuam tshuam hauv qab. Cov qauv tsim tshwj xeeb yog li no tuaj yeem tsim kho rau cov xwm txheej hauv qab sib txawv thiab txoj hauv kev nuv ntses.
Hnyav-Lub luag haujlwm tsim kho rau kev lag luam trawling
Lub qhov rooj trawl raug cuam tshuam rau kev thauj khoom tsis tu ncua hydrodynamic, rub nro, cuam tshuam thiab, hauv qab -trawling daim ntawv thov, tiv tauj nrog dej hiav txwv.
Vim li no, lub zog muaj zog yog suav nrog ua ke nrog kev ua haujlwm hydrodynamic. Cov chaw txhawb zog, stiffeners, cov ntsiab lus sib txuas thiab hnav- cov khoom tiv thaiv tuaj yeem raug teeb tsa raws li kev ua haujlwm ntawm lub qhov rooj.
Peb cov txheej txheem tsim khoom tso cai rau cov txheej txheem kev teeb tsa kom haum raws li qhov xav tau qhov rooj qhov loj, qhov chaw ua haujlwm thiab daim ntawv thov nkoj. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum lub qhov rooj siv rau kev xav tau kev lag luam nuv ntses qhov chaw rov xa rov qab, rov qab thiab rub qhov chaw tseem ceeb ntawm cov qauv.
Tsim los rau kev sib txawv Trawling Applications
Kev nuv ntses sib txawv yuav tsum tau sib txawv trawl - qhov rooj teeb tsa. Peb tuaj yeem muab thiab kho qhov rooj trawl rau cov ntawv thov suav nrog:
Hauv qab trawling
Midwater trawling
Demersal trawling
Kev lag luam cws trawling
Ntses trawling
Offshore thiab tob -dej trawling
Nyob ntawm daim ntawv thov, tus qauv tsim tuaj yeem xaiv los yog kho raws li qhovlub nkoj horsepower, trawl net loj, towing ceev, nuv ntses qhov tob, hom hom phiaj, seabed tej yam kev mob thiab yuav tsum tau net kis.
Piv txwv li, hauv qab trawling qhov chaw tseem ceeb dua rau kev ruaj ntseg, hauv qab kev sib cuam tshuam thiab hnav tsis kam, thaum cov ntawv thov hauv nruab nrab muab qhov tseem ceeb rau hydrodynamic efficiency, controllability thiab tswj qhov tob yuav tsum tau. Kev tshawb fawb kuj tau pom tias qhov tshwj xeeb siab - nqa cov qauv tsim tuaj yeem tsim rau ob qho tib si hauv qab thiab hauv nruab nrab daim ntawv thov.
Customized Trawl Qhov Rooj Tsim
Peb tsis kho qhov rooj trawl li ib qho -size- haum- tag nrho cov khoom.
Ua ntej ntau lawm, lub qhov rooj tuaj yeem sib phim rau cov neeg siv khoomtrawl net qhov ntev thiab lub nkoj ua haujlwm tsis ua haujlwm. Cov ntsiab lus tseem ceeb ntawm kev tsim qauv muaj xws li:
Qhov rooj hom thiab profile
Qhov rooj thiab qhov ntev
Aspect ratio
Camber thiab ntawv ci geometry
Qhov hnyav thiab qhov nruab nrab ntawm lub ntiajteb txawj nqus
Kev sib txuas thiab cov ntsiab lus rigging
Cov qauv kev txhawb zog
Hauv qab khau configuration
Yuav tsum tau kab rov tav net kis
Towing ceev thiab ua haujlwm tob
Qhov no tso cai rau lub qhov rooj trawl tau teeb tsa ua ib feem ntawm kev ua tiav trawl system es tsis yog ib qho kev ywj pheej.
