Isixazululo Sesistimu Yokulawula Ukuqina
Bheka eduze kwakho, imikhiqizo eminingi oyibonayo noyisebenzisayo ikhiqizwa kusetshenziswa uhlobo oluthile lwesistimu yokulawula ukungezwani. Kusukela ephaketheni lokusanhlamvu ekuseni ukuya kulebula esebhodleleni lamanzi, yonke indawo lapho uya khona kukhona izinto ezithembele ekulawuleni ukungezwani okunembile enqubweni yokukhiqiza. Izinkampani emhlabeni jikelele ziyazi ukuthi ukulawula ukungezwani okufanele kuyisici “sokwenza noma ukunqamula” salezi zinqubo zokukhiqiza. Kodwa kungani? Kuyini ukulawulwa kwengcindezi futhi kungani kubaluleke kangaka ekukhiqizeni?
Ngaphambi kokuthi singeneukulawula ukungezwani, kufanele siqale siqonde ukuthi kuyini ukungezwani. I-tension amandla noma ukushuba kwesimo esisetshenziswa entweni eyibangela ukuthi yelule iqonde ngalapho kusetshenziswe khona amandla. Ekukhiqizeni, lokhu kuvame ukuqala lapho impahla eluhlaza idonselwa enqubeni ngendawo yenqubo engezansi komfula. Sichaza ukungezwani njengetorque esetshenziswa enkabeni yomqulu, ihlukaniswe ngerediyasi yomqulu. Ukushuba = I-Torque/Radius (T=TQ/R). Uma i-tension iphezulu kakhulu, ukungezwani okungafanele kungabangela okokusebenza ukuthi kunwebe futhi kucekele phansi ukwakheka kwe-roll, noma kulimaze umqulu uma ukushuba kudlula amandla okugunda wento. Ngakolunye uhlangothi, ukungezwani okukhulu kungalimaza umkhiqizo wakho wokugcina. Ukungezwani okunganele kungabangela i-reel yokuthatha ukuba inwetshwe noma ihlehle, ekugcineni kubangele umkhiqizo oqediwe wekhwalithi embi.
I-Tension Equation
Ukuze siqonde ukulawula ukungezwani, sidinga ukuqonda ukuthi iyini “iwebhu”. Leli gama lisho noma iyiphi into edluliswa ngokuqhubekayo kusukela kumqulu wephepha, ipulasitiki, ifilimu, imicu, indwangu, ikhebula noma insimbi. Ukulawula ukucindezeleka kuyisenzo sokugcina ukungezwani okufiswayo kuwebhu njengoba kudingwa okokusebenza. Lokhu kusho ukuthi ukungezwani kuyalinganiswa futhi kugcinwe endaweni ebekiwe ukuze iwebhu isebenze kahle kuyo yonke inqubo yokukhiqiza. Ukuqina ngokuvamile kukalwa kusetshenziswa isistimu yokulinganisa ye-imperial ngamaphawundi ayintshi ngayinye (i-PLI) noma i-metric ngama-Newtons ngesentimitha (N/cm).
Ukulawula ukushuba okufanelekile kuklanyelwe ukulawula ngokunembile ukungezwani kuwebhu, ngakho kufanele kulawulwe ngokucophelela futhi kugcinwe ezingeni elincane kuyo yonke inqubo. Umthetho wesithupha uwukusebenzisa inani elincane lokudonsa kanzima ongayithola ukuze ukhiqize umkhiqizo wokugcina owufunayo. Uma ukungezwani kungasetshenziswa ngokunembile kuyo yonke inqubo, kungaholela ekushwabaneni, ukuphuka kwewebhu, kanye nemiphumela yenqubo engemihle njengokuhlukanisa (ukugunda), ukuphuma kwegeji (ukuphrinta), ukushuba okungahambisani (i-coating), ukuhluka kobude (i-laminating ), ukugoqa kwempahla ngesikhathi senqubo yokucwala, kanye nokukhubazeka kwe-spooling (ukwelula, ukufaka inkanyezi, njll.), ukusho nje okumbalwa.
Abakhiqizi badinga ukuhlangabezana nesidingo esikhulayo ukuze bakhiqize imikhiqizo yekhwalithi ngendlela ephumelelayo ngangokunokwenzeka. Lokhu kuholela esidingweni sokusebenza okungcono, okuphezulu kanye nemigqa yokukhiqiza yekhwalithi ephezulu. Kungakhathaliseki ukuthi inqubo iyashintsha, isika, iphrinta, i-laminating noma enye inqubo, ngayinye inento eyodwa efanayo - ukulawulwa kokucindezeleka okufanele kuphumela ekukhiqizeni okuphezulu, okungabizi kakhulu.
Ishadi Lokulawula Ukungezwani Kwezandla
Kunezindlela ezimbili eziyinhloko zokulawula ukungezwani, okwenziwa ngesandla noma okuzenzakalelayo. Endabeni yokulawula okwenziwa ngesandla, ukunaka nokuba khona ko-opharetha kuhlala kudingekile ukuze ulawule futhi ulungise isivinini kanye ne-torque kuyo yonke inqubo. Kulawulo oluzenzakalelayo, isisebenzisi sidinga kuphela ukwenza okokufaka phakathi nokusetha kokuqala, njengoba isilawuli sinesibopho sokugcina ukungezwani okufunayo kuyo yonke inqubo. Lokhu kunciphisa ukusebenzisana komsebenzisi nokuncika. Emikhiqizweni yokulawula okuzenzakalelayo, ngokuvamile kunezinhlobo ezimbili zezinhlelo, iluphu evulekile kanye nokulawula iluphu evaliwe.
