Indlela yokulinganisa iselfowuni, kutheni calibhirate?

Iiseli zomthwalo zizinto ezikhethekileyo zabasebenzi ezisetyenziselwa ukulinganisa ubunzima okanye amandla kuluhlu olubanzi lwezicelo. Ziyintloko yokulinganisa iinkqubo kumashishini njenge-aerospace, ukuthunyelwa, kunye nemoto. Oku kusivumela ukuba siqokelele idatha echanekileyo yokuvavanya. Iiseli zomthwalo zokulinganisa ziphambili zokufunda ngokuchanekileyo. Oku kuyanceda ukuphepha imiba engafunekiyo. Kubalulekile ukukhangela kwaye uzidibanise rhoqo.

Iiseli zomthwalo zibonisa iimpawu zokunxiba emva kweminyaka embalwa yokusetyenziswa. Oku kuthetha ukuba sizisebenzisa kangakanani iiseli zomthwalo kunye nendlela ubushushu ngayo. Ezi zinto zinokwenza iminyaka emidlule ngokukhawuleza. Ukungasebenzi kakuhle kunokuvela kwimithombo eyahlukeneyo.

Oku kubandakanya:

• Intambo kunye neempazamo zomatshini

• Ukwakhiwa kwezixhobo

• Isiphene somatshini

• Ufakelo olungachanekanga

• Iingxaki zombane

Ukulungelelanisa rhoqo kubalulekile. Igcina imithwalo ichanekile kwaye isebenze ngokufanelekileyo. Ngaphandle kokulinganisa rhoqo, iiseli ezilayishweni zinokunika ukufundwa okungachanekanga kwaye kuvelise idatha yempazamo.

Ukulinganisa rhoqo kweeseli zomthwalo kunokunceda ekufezekiseni ukuchaneka kwe-0.03 ukuya kwi-1%. Iiseli ezilayishayo zifuna ukulinganisa ukuhlangabezana nemigangatho yesizwe. Oku kuqinisekisa uxanduva kwimveliso, ukhuseleko, kunye nokuthotyelwa kwinkqubo yolawulo lomgangatho.

Uvavanyo lwangaphambili:

Jonga ukuba umatshini unika idatha yokulinganisa echanekileyo ngaphambi kokuba icule iseli yomthwalo.

Nazi izikhombisi ezintathu eziphambili ukukhangela ukusebenza kakuhle kweseli yomthwalo kunye nesamente. Oku kubandakanya: Xa inkqubo ikhupha, isalathiso sobunzima kufuneka sibuyele kwi-zero. Xa uphinda-phinda ubunzima, kufuneka kabini ubunzima bomzimba obonisiweyo. Isalathisi sobunzima kufuneka sibonise ukufundwa okufanayo akukho nto ihleli kuyo umthwalo. Ukuba uhlangabezana neemeko ezingentla, unokuthemba ukuba iseli yomthwalo imithwalo. Intambo ephosakeleyo okanye ufakelo olungalunganga lunokubangela ukuba iseli yomthwalo inike ukufundisisa okungachanekanga.

Iseli yomthwalo we-stc

Ngaphambi kokuba ucolise iseli yomthwalo, jonga ezi:

• Iintambo

• Iingcingo

Sebenzisa iiseli zomthwalo wedummy kude kuqhubeke nokwakha i-welding. Ukuba iseli yomthwalo ibonakala ingumbandela emva kovavanyo lokuqala, yenza ezi mvavanyo:

Ukuhlolwa komzimba:

Jonga iseli yomthwalo womonakalo womzimba. Kananjalo, jonga iidenti kwaye uqhekeze kuwo onke amacala amane. Ukuba iseli yomthwalo itshintshe imilo, njengokuba umntu esebenzisana, egoba, okanye elula, kufuneka uyitshintshe.

Ukunganyangeki kwebhulorho:

Vavanya oku xa kungabikho mthwalo ukhoyo, kwaye unqamle inkqubo evela kumlawuli wobunzima. Jonga umnyhadala ukhokelela ekungathinteli. Ke, hlolisisa umqondiso wokukhokela ukupasa. Thelekisa ukufundwa kunye nenkcazo yeseli yomthwalo. Iindlela zokunyamezelana zihlala zibangelwa kukuguquguquka kwamandla.

I-Zero Ibhalansi:

Uxinzelelo lwentsalela kwingingqi yemvakalelo ihlala ibangela utshintsho kwi-zero. Iseli yomthwalo wakhela uxinzelelo lwentsalela xa abasebenzisi balilayisha amaxesha amaninzi ngemijikelezo yayo. Jonga iziphumo zeseli yomthwalo kunye ne-voltmeter xa inkqubo ingenanto. Imele ibe ngaphakathi kwi-0.1% yemiqondiso ye-zero yokuphuma ekhankanywe apha ngasentla. Ukuba i-zero leroli ye-Insile igqitha, inokonakalisa iseli.

Ukungaxhathisi ukuphakama:

Qhagamshela igalelo, iziphumo kunye nomhlaba zikhokelela. Ngoncedo lwe-ourem, jonga ukumelana phakathi kweseli yomthwalo kunye nezikhokelo. Ukuba ukufunda akufikeleli kwi-5000 megohms, hlula i-wire yomhlaba kwaye uphinde uvavanyo. Ukuba iyasilela kwakhona, umonakalo unokwenzeka kwiseli. Ukulandela la manyathelo kunceda ifowuni yomthwalo kakuhle. Ikwathintela ukonakala okunokwenzeka.

Ndizonda njani iseli yomthwalo?

Ukulinganisa okumiselweyo kukhangela izinto ezimbini: ukuphindaphinda kunye nobucala. Zombini ezi zinto zifuna ukumisela ukuchaneka. Indlela ye 'Point' yeyona ixhaphakileyo. Kule ndlela, umvavanyi wongeza umthwalo owaziwayo kwisisele somthwalo emanyukeni. Sirekhoda ukufundwa kwinqanaba ngalinye. Umzekelo, iseli yomthwalo onamandla okuba ziitoni ezili-100 uthatha ukufundwa xa umntu esebenzisa umthwalo wama-20, 40, 80, 80, ne-100 yeetoni. Le nkqubo yenzeka kabini. Umahluko kwiziphumo ubonakalisa ukuba zichanekile kangakanani kwaye ziphindwe. Cela iseli yomthwalo kunye nomboniso okanye ukufundwa njengeyunithi. Oku kubalulekile kuba iiseli ezininzi zomthwalo ziyinxalenye yenkqubo yobunzima. Soloko usenza oku kunye xa unako.

(3) Qhoboshela i-rack ubunzima. Qinisekisa ukuba ubunzima bomsindo rack ractor chars chars charring intloko yenzwa.

(4) Hlala ubunzima bomzimba kwi-rack ubunzima.

(5) Qhagamshela ubonelelo lwebhulorho kwiseli yomthwalo. Emva koko, nxibelelanisa imveliso kwindawo enobuganga bokungabi-millivolt. Qiniseka ukuba ukuchaneka kwemitha kungaphezulu kwe-70% yokuchaneka kombane. Ukuba iyafuneka, ungalinganisa ixabiso langoku.

. Oku kuxhomekeke kwiiselfowuniUluhlu kunye nenani lamanqaku emilinganiselo. Rekhoda idatha evela kwimveliso yeseli yomthwalo. Singakwazi ukukhangela izalathi zentsebenzo, kubandakanya ukukhutshwa kwe-zero, ukuchaneka komgca, ukuchaneka okuphindiweyo, kunye ne-hysteresis. Singabona ukuba iseli yomthwalo iqhelekile kwaye inomgangatho olungileyo.
