Kupatsanura
Ma electrothermal alloys: zvichienderana nehuwandu hwemakemikari uye chimiro chawo, anogona kukamurwa muzvikamu zviviri:
Imwe yacho imhando yesimbi-chromium-aluminium alloy series,
Imwe yacho imhando ye nickel-chromium alloy series, ine zvayakanakira sezvinhu zvinodziya zvemagetsi, uye inoshandiswa zvakanyanya.
Chinangwa chikuru
Michina yesimbi, kurapwa, indasitiri yemakemikari, zvedongo, zvemagetsi, zvemagetsi, zvegirazi nezvimwe zvekushandisa pakudziisa maindasitiri pamwe nemidziyo yekudziisa yehurumende.
Zvakanakira nezvayakaipira
1. Zvakanakira zvikuru nezvakaipa zvemhando yesimbi-chromium-aluminium alloy: Zvakanakira: iron-chromium-aluminium electric heating alloy ine tembiricha yepamusoro yebasa, tembiricha yepamusoro yebasa inogona kusvika 1400 degrees, (0Cr21A16Nb, 0Cr27A17Mo2, nezvimwewo), hupenyu hurefu hwebasa, mutoro wepamusoro, uye kuramba kwakanaka kweoxidation, resistivity yakanyanya, yakachipa nezvimwewo. Zvakashata: Simba rakaderera zvakanyanya patembiricha yepamusoro. Sezvo tembiricha ichiwedzera, plasticity yayo inowedzera, uye zvikamu zvinoshanduka nyore nyore, uye hazvisi nyore kukotama nekugadzirisa.
2. Zvakanakira zvikuru nezvakaipa zve nickel-chromium electric heating alloy series: Zvakanakira: simba rekupisa rakakwirira rakakwirira kupfuura re iron-chromium-aluminium, harisi nyore kuchinjika kana richishandiswa pakupisa kwakakwirira, chimiro charo hachina kuchinjika nyore, plasticity yakanaka, iri nyore kugadzirisa, ine emissivity yakawanda, haina magineti, haigone ngura. Yakasimba, inogara kwenguva refu, nezvimwewo. Zvakashata: Nekuti yakagadzirwa nezvinhu zvisingawanzoitiki zve nickel metal, mutengo wezvigadzirwa izvi wakakwira kanoverengeka kupfuura weFe-Cr-Al, uye tembiricha yekushandisa yakaderera pane yeFe-Cr-Al.
zvakanaka nezvakaipa
Chekutanga, tinofanira kuziva kuti waya yekupisa inosvika pakupisa kwakatsvuka, izvo zvine chekuita nekurongeka kwewaya yekupisa. Ngatitangei tabvisa muchina wekuomesa bvudzi tocheka chikamu chewaya yekupisa. Ne 8V 1A transformer, kuramba kwewaya yekupisa kana waya yekupisa yegumbeze remagetsi hakufanirwe kunge kuri pasi pe 8 ohms, zvikasadaro transformer ichatsva zviri nyore. Ne 12V 0.5A transformer, kuramba kwewaya yekupisa hakufanirwe kunge kuri pasi pe 24 ohms, zvikasadaro transformer ichatsva zviri nyore. Kana waya yekupisa yasvika pakupisa kwakatsvuka, kutsvuka kuri nani, unofanira kushandisa 8V 1A transformer, uye simba rayo rakakura kupfuura re 12V 0.5A transformer. Nenzira iyi, tinogona kuyedza zviri nani zvakanakira nekuipira kwewaya yekupisa.
1. Kupisa kwakanyanya kwekushanda kwechikamu kunoreva kupisa kwepamusoro kwechikamu chacho mumhepo yakaoma, kwete kupisa kwechoto kana chinhu chinodziya. Kazhinji, kupisa kwepamusoro kunenge madhigirii zana kupfuura kupisa kwechoto. Saka, tichifunga nezvezvikonzero zviri pamusoro apa, mukugadzira, cherechedzai kupisa kwekushanda kwezvikamu. Kana tembiricha yekushanda ikapfuura muganho wakati, oxidation yezvikamu pachayo ichakurumidza uye kuramba kupisa kuchaderedzwa. Kunyanya zvikamu zvesimbi-chromium-aluminium electric heating alloy zviri nyore kukanganisika, kuputsika, kana kutotyoka, izvo zvinopfupisa hupenyu hwebasa. .
2. Tembiricha yepamusoro yekushandisa yechikamu ichi ine hukama hwakakura nedhayamita yewaya yechikamu ichi. Kazhinji, tembiricha yepamusoro yekushandisa yechikamu ichi inofanira kunge ine dhayamita yewaya isingapfuure 3mm, uye ukobvu hwemutsara wakatsetseka haufanire kunge uri pasi pe2mm.
3. Pane hukama hwakakura pakati pemhepo inoparadza iri muchoto nekupisa kwakanyanya kushanda kwezvikamu, uye kuvapo kwemhepo inoparadza kunowanzo kukanganisa tembiricha yekushanda uye hupenyu hwebasa rezvikamu.
4. Nekuda kwesimba rakaderera resimbi-chromium-aluminium pakupisa kwakanyanya, zvikamu zvacho zvinokanganisika nyore nyore pakupisa kwakanyanya. Kana dhayamita yewaya isina kusarudzwa zvakanaka kana kuiswa kwayo kusina kunaka, zvikamu zvacho zvinoputsika uye zvinofamba-famba kwenguva pfupi nekuda kwekushanduka-shanduka kwekupisa kwakanyanya. Saka, zvinofanirwa kufungwa nezvazvo pakugadzira zvikamu.
5. Nekuda kwemakemikari akasiyana-siyana esimbi-chromium-aluminium, nickel, chromium nedzimwe mhando dzemagetsi dzinopisa, tembiricha yekushandisa uye kuramba kwe oxidation zvinotsanangurwa nemusiyano we resistivity, iyo inoonekwa mu iron-chromium heat alloy material Al element ye resistivity, Ni-Cr electric heating alloy material inosarudza resistivity ye element Ni. Pasi pemamiriro ekupisa kwakanyanya, oxide film yakagadzirwa pamusoro pe alloy element inosarudza hupenyu hwebasa. Nekuda kwekushandiswa kwenguva refu, chimiro chemukati che element chinogara chichichinja, uye oxide film yakagadzirwa pamusoro iri kukwegura uye kuparadzwa. Zvinhu zviri mukati mezvikamu zvayo zvinogara zvichishandiswa. Zvakadai seNi, Al, nezvimwewo, nokudaro zvichipfupisa hupenyu hwebasa. Naizvozvo, pakusarudza waya yedhayamita yewaya yemagetsi, unofanirwa kusarudza waya yakajairwa kana bhandi rakakora rakati sandara.
