Tension Control System Solution
Tarisa zvakakukomberedza, zvizhinji zvezvigadzirwa zvaunoona nekushandisa zvinogadzirwa uchishandisa imwe mhando yetension control system. Kubva pasuru yezviyo mangwanani kusvika kune iyo label pabhodhoro remvura, kwese kwaunoenda kune zvinhu zvinotsamira pane chaiyo tension control mukugadzira maitiro. Makambani kutenderera pasirese anoziva kuti kwakaringana kudzora kushushikana ndiko "kugadzira kana kuputsa" chimiro chemaitiro aya ekugadzira. Asi nei? Chii chinonzi tension control uye nei yakakosha mukugadzira?
Tisati tanyuratension control, tinofanira kutanga tanzwisisa kuti makakatanwa chii. Kutsikirira (Tension in English) zvinoreva simba kana kukandirana kunoiswa pachinhu chinoita kuti chitambure chakananga kune simba rinoshandiswa. Mukugadzira, izvi zvinowanzotanga kana iyo mbishi inodhonzwa mukati meiyo nzira neinodzika nzira. Isu tinotsanangura tension se torque inoshandiswa pakati pemupumburu, yakakamurwa neiyo roll radius. Tension = Torque/Radius (T=TQ/R). Kana tension yakanyanya kuwanda, kudhonzerana kwakashata kunogona kuita kuti zvinhu zvirebe uye zviparadze chimiro chemupumburu, kana kutokuvadza mupumburu kana kukakavara kwakapfuura simba rekugera rechinhu. Kune rumwe rutivi, kunyanya kunetseka kunogona kukanganisa chigadzirwa chako chekupedzisira. Kusakwana tension kunogona kuita kuti take-up reel itambanuke kana kunyungudika, zvichizoguma neshomeka yemhando yepamusoro chigadzirwa.
Tension Equation
Kuti tinzwisise kudzora kushushikana, isu tinofanirwa kunzwisisa kuti "webhu" chii. Iri izwi rinoreva chero chinhu chinoramba chichifambiswa kubva mupumburu webepa, plastiki, firimu, filament, machira, tambo kana simbi. Tension control chiitiko chekuchengetedza tension inodiwa pawebhu sezvinodiwa nechinhu. Izvi zvinoreva kuti tension inoyerwa uye inochengetwa panzvimbo yainodiwa kuitira kuti dandemutande rifambe zvakanaka mukati mekugadzira. Tension inowanzopimwa pachishandiswa imperial measurement system mumapounds per linear inch (PLI) kana metric muNewtons per centimita (N/cm).
Kudzora tension kwakaringana kwakagadzirirwa kunyatso kudzora kunetsa padandemutande, saka inofanirwa kudzorwa nemazvo uye kuchengetwa kusvika padanho diki mukati mekuita. Mutemo wechigunwe ndewekumhanyisa huwandu hushoma hwekunetsana hwaunogona kuwana kuti uburitse chemhando yepamusoro chigadzirwa chaunoda. Kana tension ikasaiswa nemazvo mukati mekuita uku, inogona kukonzeresa kuunyana, kubhuroka kwewebhu, uye kutadza kuita mhedzisiro senge interleaving (kuveura), kunze-kwegauge (kudhinda), kusapindirana kwekupfeka ukobvu (coating), kureba kusiyana (laminating. ), kupeta kwezvinhu panguva yekucheneswa, uye kuremara (kutambanudza, nyeredzi, nezvimwewo), kungotaura zvishoma.
Vagadziri vanofanirwa kusangana nekukura kuri kudiwa kuti vagadzire zvigadzirwa zvemhando yepamusoro sezvinobvira. Izvi zvinotungamira kudikanwa kwezviri nani, kuita kwepamusoro uye mitsara yemhando yepamusoro yekugadzira. Kunyangwe iyo nzira iri kushandura, kucheka, kudhinda, laminating kana chero imwe nzira, imwe neimwe ine chinhu chimwe chete chakafanana - kwakakodzera tension control inoguma nemhando yepamusoro, inodhura-inoshanda kugadzirwa.
Manual Tension Control Chart
Pane nzira mbiri huru dzekudzora tension, manual kana automatic. Panyaya yekutonga kwemanyorero, kutarisisa uye kuvapo kweanoshanda kunogara kuchidikanwa kuitira kubata uye kugadzirisa kumhanya uye torque mukati mekuita. Mune otomatiki kudzora, mushandisi anongoda chete kuita zvekupinza panguva yekutanga kuseta, sezvo mutongi ane basa rekuchengetedza tension inodiwa mukati mekuita. Izvi zvinoderedza kudyidzana kwevashandisi uye kutsamira. Mune zvigadzirwa zveotomatiki zvekutonga, pane kazhinji mhando mbiri dzemasisitimu, yakavhurika loop uye yakavharwa loop control.
