Tarisa-tarisa uye zvakawanda zvezvigadzirwa zvaunoona nekushandisa zvinogadzirwa uchishandisa imwe mhando yetension control system. Kwese kwese kwaunotarisa, kubva pazviyo zvekurongedza kusvika kune zvinyorwa pamabhodhoro emvura, pane zvinhu zvinoenderana nekunyatso kudzora kushushikana panguva yekugadzira. Makambani kutenderera pasirese anoziva kuti kwakaringana kudzora kunetsa ibasa re "kugadzira kana kuputsa" mune idzi nzira dzekugadzira. asi nei? Chii chinonzi tension control uye nei yakakosha mukugadzira?
Tisati tanyura mukudzora kushushikana, tinofanira kutanga tanzwisisa kuti kunetsana chii. Tension (Tension) itsinhiro kana kuti tension inoiswa pachinhu chinenge chichiita kutatamura zvinhu zvichinanga kune simba rinoshandiswa. Mukugadzira, izvi zvinowanzotanga neiyo yakadzika nzira yekukwevera zvinhu mukuita. Isu tinotsanangura tension seye torque inoshandiswa pakati pemupumburu wakakamurwa neradius roll. Tension = Torque / Radius (T = TQ/R). Kana tension yakawandisa ikaiswa, kuwanda kwakashata kwekukakavadzana kunogona kuita kuti zvinhu zvirebe uye kukuvadza chimiro chemupumburu, uye inogona kutotyora mupumburu kana kukakavara kwakapfuura simba rekugera rechinhu. Nekune rumwe rutivi, kushomeka kushoma kunogonawo kukanganisa chigadzirwa chako. Kusakwana tension kunogona kutungamira kune telescopic kana sagging rewind rollers, pakupedzisira zvichikonzera hurombo hwechigadzirwa.
Kuti tinzwisise kudzora tension, tinofanira kunzwisisa inonzi "network". Izwi iri rinoreva chinhu chipi nechipi chinodyiswa nguva dzose kubva kana/kana mupumburu, sebepa, purasitiki, firimu, filament, machira, tambo kana simbi, zvichingodaro. Tension control chiito chekuchengetedza kusawirirana kunodiwa pawebhu sezvinodiwa. nezvinyorwa. Izvi zvinoreva kuti tension inoyerwa uye inochengetwa panzvimbo yainodiwa, zvichiita kuti dandemutande rifambe zvakanaka panguva yese yekugadzira. Tension inowanzoyerwa muImperial system yekuyera (mumapounds per linear inch (PLI) kana metric system (muNewtons per centimeter (N/cm).
Zvakakodzeratension controlyakagadzirirwa kuve nekukakavadzana chaiko padandemutande, saka kutambanudza kunogona kunyatsodzorwa uye kuchengetwa kusvika padiki apo uchichengetedza kushushikana padanho rinodiwa mukati mekuita. Mutemo wechigunwe ndewekumhanyisa tension yaunokwanisa kupukunyuka nayo kuti ugadzire chigadzirwa chemhando yepamusoro chaunoda. Kana tension ikasaiswa nemazvo mukati mekuita uku, zvinogona kukonzera kuunyana, kubhuroka kwewebhu uye maitiro asina kunaka akadai senge interweaving (slitting), kunyoresa (kudhinda), kusapindirana kwekupfeka kwehuku (coating), kureba kusiyana (sheet), kupeta kwezvinhu panguva. lamination, uye roll defects (telescopic, starring, etc.) kudoma mashoma.
Vagadziri vari pasi pekumanikidzwa kuti vaenderane nekukwira kuri kudiwa uye kugadzira zvigadzirwa zvemhando yepamusoro sezvinobvira. Izvi zvinotungamira kudikanwa kwezviri nani, kuita kwepamusoro uye mitsara yemhando yepamusoro yekugadzira. Ingave kushandura, kutsemura, kudhinda, laminating, kana mamwe maitiro, imwe neimwe yeaya maitirwo ane hunhu hwakafanana - kwakakodzera tension control mutsauko uripo pakati pemhando yepamusoro, inodhura-inoshanda kugadzirwa uye yakaderera-mhando, inodhura kugadzirwa kusawirirana, zvakawandisa zvimedu uye. kuvhiringidzika pamusoro pematande akaputsika.
Pane nzira mbiri huru dzekudzora tension, manual kana otomatiki. Nezvinodzora zvemanyorero, mushandisi anoda kugara achitariswa uye kuvapo kubata uye kugadzirisa kumhanya uye torque mukati mekuita. Nekutonga otomatiki, mushandisi anongoda kuisa mukati mekutanga kuseta, sezvo mutongi anotarisira kuchengetedza tension inodiwa mukati mekuita. Nokudaro, kushamwaridzana kwevashandisi uye kutsamira kunoderedzwa. Mune zvigadzirwa zveotomatiki zvekutonga, mhando mbiri dzemasisitimu dzinowanzo kupihwa, yakavhurika-loop uye yakavharwa-loop control.
Vhura loop system:
Mune yakavhurika-loop system, pane zvinhu zvitatu zvakakosha: controller, torque mudziyo (brake, clutch, kana drive), uye mhinduro sensor. Mafeedback sensors anowanzo kutarisana nekupa dhayamita referensi mhinduro, uye maitiro anodzorwa zvakaenzanirana kune dhayamita chiratidzo. Kana iyo sensor inoyera shanduko yedhayamita uye ichiendesa chiratidzo ichi kune controller, mutongi anogadzirisa zvakaenzanirana torque yebhureki, clutch kana dhiraivha kuchengetedza kushushikana.
Yakavharwa loop system:
Kubatsira kweiyo yakavharwa-loop system ndeyokuti inoramba ichitarisa uye inogadzirisa tension yewebhu kuti ichengetedze pane inodiwa yakatarwa, zvichikonzera 96-100% kunyatsoita. Kune yakavharwa-loop system, pane zvinhu zvina zvakakosha: controller, torque mudziyo (brake, clutch kana drive), tension yekuyeresa mudziyo (yekutakura sero), uye kuyerwa chiratidzo. Iyo controller inogamuchira yakananga kuyera zvinhu mhinduro kubva kune rekutakura sero kana swing ruoko. Sezvo tension ichichinja, inoburitsa chiratidzo chemagetsi icho mutongi anoturikira maererano nekukakavadzana kwakaiswa. Iyo controller inozogadzirisa torque ye torque yekuburitsa mudziyo kuchengetedza yaunoda set point. Sezvinongoita cruise control inoita kuti mota yako irambe ichimhanya yakagara yaiswa, inovhara-loop tension control system inoita kuti roll tension yako irambe iri preset tension.
Saka, iwe unogona kuona kuti munyika yekutonga kwemakakatanwa, "yakanaka zvakakwana" kazhinji haina kunaka zvakakwana. Kudzora tension chikamu chakakosha chemhando ipi neipi yekugadzirwa kwemhando yepamusoro, kazhinji ichisiyanisa "yakanaka zvakakwana" kugadzirwa kubva kune zvemhando yepamusoro zvinhu uye kugadzirwa kwemagetsi echigadzirwa chekupedzisira. Kuwedzera otomatiki tension control system inowedzera iripo uye yeramangwana hunyanzvi hwekuita kwako uku uchiunza zvakakosha zvakanakira iwe, vatengi vako, vatengi vavo uye nevamwe. Labirinth's tension control system yakagadzirirwa kuve yekudonhedza-mumhinduro kumashini ako aripo, ichipa kukurumidza kudzoka pakudyara. Kunyangwe iwe uchida yakavhurika-loop kana yakavharwa-loop sisitimu, Labirinth ichakubatsira iwe kuona izvi uye kukupa iwe kugadzira uye purofiti yekuwana iwe yaunoda.
