Yiziphi izindawo ezinokhahlo okufanele amaseli wakho womthwalo amelane nazo?
Lesi sihloko sichaza indlela yokukhetha alayisha iseliezosebenza ngokwethembeka ezimweni ezinzima nasezimeni zokusebenza ezinzima.
Amaseli omthwalo ayizingxenye ezibalulekile kunoma iyiphi isistimu yokukala, ezwa isisindo sempahla ku-hopper yokukala, esinye isiqukathi noma amathuluzi okucubungula.Kwezinye izinhlelo zokusebenza, amaseli omthwalo angase abekwe endaweni enzima enamakhemikhali abolayo, uthuli olusindayo, amazinga okushisa aphezulu, noma umswakama owedlulele ophuma kumishini yokugezwa enomthamo omkhulu woketshezi.Noma iseli lomthwalo lingase livezwe ekudlidlizeni okuphezulu, imithwalo engalingani, noma ezinye izimo zokusebenza ezinzima.Lezi zimo zingaholela emaphutheni okulinganisa futhi, uma kukhethwe ngokungalungile, ngisho nokulimaza iseli yomthwalo.Ukuze ukhethe iseli elifanele lokulayisha lohlelo olufunayo, udinga ukuqonda ngokugcwele izimo zakho zemvelo nokusebenza, nokuthi yiziphi izici zeseli yokulayisha ezifaneleka kangcono ukuzisingatha.
Yini eyenza iisicelokunzima?
Sicela ubhekisise kahle indawo ezungeze isistimu yokukala nokuthi isistimu kufanele isebenze ngaphansi kwaziphi izimo zokusebenza.
Ingabe indawo izoba nothuli?
Ingabe isistimu yokukala izovezwa emazingeni okushisa angaphezu kuka-150°F?
Injani ikhemikhali yezinto ezikalwayo?
Ingabe uhlelo luzogezwa ngamanzi noma esinye isisombululo sokuhlanza?Uma kuzosetshenziswa amakhemikhali okuhlanza ukuze kushaywe imishini, yiziphi izici zawo?
Ingabe indlela yakho yokuwasha iveza iseli lomthwalo kumswakama omningi?Ingabe uketshezi luzofuthwa ngomfutho ophezulu?Ingabe iseli lomthwalo lizocwiliswa oketshezini ngesikhathi sokushaywa?
Ingabe amaseli omthwalo angalayishwa angalingani ngenxa yokwakheka kwezinto noma ezinye izimo?
Ingabe uhlelo luzobhekana nokushaqeka (imithwalo emikhulu engazelelwe)?
Ingabe umthwalo ofile (isitsha noma okokusebenza okuqukethe izinto) wesistimu yokukala mkhulu ngokulinganayo kunomthwalo ophilayo (impahla)?
Ingabe isistimu izoba ngaphansi kokudlidliza okuphezulu okuvela ezimotweni ezidlulayo noma eziseduze ezicutshungulwayo noma izisetshenziswa zokuphatha?
Uma uhlelo lokukala lusetshenziswa emishinini yenqubo, ingabe uhlelo luzoba ngaphansi kwamandla aphezulu e-torque avela kumamotho wemishini?
Uma usuqonda izimo ezizobhekana nazo uhlelo lwakho lokukala, ungakhetha iseli lomthwalo elinezici ezifanele ezingeke nje zimelane nalezo zimo, kodwa ezizosebenza ngokwethembeka ngokuhamba kwesikhathi.Ulwazi olulandelayo luchaza ukuthi iziphi izici zeseli yokulayisha ezitholakalayo ukuphatha uhlelo lwakho lokusebenza olufunayo.
Izinto zokwakha
Ukuze uthole usizo lokukhetha iseli lomthwalo elifanele lezidingo zakho ezifunekayo, thintana nomhlinzeki weseli onolwazi olunzulu noma umxhumanisi ozimele wokuphatha ama-solids amaningi.Lindela ukunikeza ulwazi oluningiliziwe mayelana nezinto ezizophathwa isistimu yokukala, indawo yokusebenza, nokuthi yiziphi izimo ezizothinta ukusebenza kweseli lomthwalo.
I-load cell iyingxenye yensimbi egobayo ephendula umthwalo osetshenzisiwe.Le elementi ihlanganisa amageji obunzima kusekethe futhi ingenziwa ngensimbi yamathuluzi, i-aluminium noma insimbi engagqwali.Insimbi yamathuluzi iyinto evamile kakhulu yamaseli okulayisha ezinsizeni ezomile ngoba inikeza ukusebenza okuhle ngenani eliphansi futhi inikeza ububanzi bomthamo omkhulu.Amaseli omthwalo wensimbi wamathuluzi ayatholakala kukho kokubili iphuzu elilodwa kanye neseli yomthwalo we-multipoint (eyaziwa ngokuthi izinhlelo zokusebenza zephoyinti elilodwa ne-multipoint).Isebenza kahle kakhulu ezimeni ezomile, njengoba umswakama ungagqwala izinsimbi zamathuluzi.Ingxubevange yensimbi ethandwa kakhulu kulawa maseli omthwalo wuhlobo 4340 ngoba kulula ukuwenza ngomshini futhi ivumela ukwelashwa okufanele kokushisa.Iphinde ibuyele esimweni sayo sokuqala ngemuva kokususwa komthwalo osetshenzisiwe, ukunciphisa ukukhuphuka (ukwanda kancane kancane kokufundwa kwesisindo seseli lapho kusetshenziswa umthwalo ofanayo) kanye ne-hysteresis (izisindo ezimbili zomthwalo ofanayo osetshenzisiwe Umehluko phakathi kokufundwa, okukodwa etholwe ngokukhuphula umthwalo usuka ku-zero futhi omunye ngokunciphisa umthwalo ufinyelele kumthamo omkhulu olinganiselwe weseli yomthwalo).I-Aluminium iyinto ebiza kancane yomthwalo weseli futhi ngokuvamile isetshenziselwa ukulayisha amaseli endaweni eyodwa, izinhlelo zokusebenza zevolumu ephansi.Le nto ayifanele ukusetshenziswa ezindaweni ezimanzi noma zamakhemikhali.Thayipha i-aluminium engu-2023 edume kakhulu ngoba, njengohlobo lwensimbi yensimbi engu-4340, ibuyela endaweni yayo yokuqala ngemuva kokukalwa, ikhawulele ukukhasa kanye ne-hysteresis.Amandla nokumelana nokugqwala kwe-17-4 PH (okunqunyelwe udokotela) insimbi engagqwali (eyaziwa nangokuthi i-grade 630 insimbi engagqwali) ikunikeza ukusebenza okungcono kakhulu kukonke kwanoma yikuphi okuphuma kwensimbi engagqwali kumaseli omthwalo.Le alloy ibiza kakhulu kunensimbi yamathuluzi noma i-aluminium, kodwa inikeza ukusebenza okungcono kakhulu kwanoma iyiphi into ezindaweni ezimanzi (okungukuthi lezo ezidinga ukuwashwa okubanzi) kanye nezinhlelo zokusebenza ezinolaka lwamakhemikhali.Kodwa-ke, amanye amakhemikhali azohlasela ama-alloys oHlobo lwe-17-4 PH.Kulezi zinhlelo zokusebenza, inketho eyodwa ukusebenzisa ungqimba oluncane lukapende lwe-epoxy (kusuka ku-1.5 kuya ku-3 mm ubukhulu) kuya kuseli lomthwalo wensimbi engenasici.Enye indlela ukukhetha iseli lomthwalo elenziwe ngensimbi ye-alloy, elingamelana kangcono nokugqwala.Ukuze uthole usizo ekukhetheni impahla yeseli yomthwalo efanelekile yokusetshenziswa kwamakhemikhali, bheka amashadi okumelana namakhemikhali (amaningi atholakala ku-inthanethi) futhi usebenzisane eduze nomphakeli wakho weselula.
