Thermocouples ndeimwe yeanonyanya kushandiswa mhando dzematembiricha sensors pasi rese. Ivo vanozivikanwa munzvimbo dzakasiyana siyana nekuda kwehupfumi hwavo, kusimba uye kuita zvakasiyana. Thermocouple application inotangira kubva kumakeramiki, magasi, oiri, simbi, girazi uye mapurasitiki kune chikafu nezvinwiwa.
Unogona kuzvishandisa chero kupi kuti utarise kana kurekodha tembiricha data. Thermocouples inozivikanwa nekugadzira zviyero zvetembiricha zvine mhinduro nekukurumidza uye yakanakisa kuramba kuvhunduka, vibration uye tembiricha yepamusoro.
A thermocouple inzwa inoshandiswa kuyera tembiricha musainzi, kugadzira, uye tekinoroji application. Inogadzirwa nekubatanidza waya mbiri dzesimbi dzakasiyana pamwe chete kuti dzigadzire mubatanidzwa. Iyo junction inogadzira voltage inofanotaurwa pamusoro petembiricha yakapihwa. Thermocouples anowanzo shandisa iyo Seebeck kana thermoelectric effect kushandura voltage kuita chiyero chetembiricha.
Thermocouples ane akawanda maapplication muindasitiri yechikafu nechinwiwa senge pasteurization, firiji, kuvirisa, kubika uye kubhodhoro. Iwe haufanirwe kunetseka kana uchishandisa thermocouple tembiricha geji sezvo ichipa kwakaringana fry uye yekubika tembiricha kuverenga kuti uve nechokwadi chekuti chikafu chako chabikwa.
Thermocouples inowanzoshandiswa mumidziyo yekudyira yakadai segrill, toasters, zvakadzika fryers, heaters, uye oveni. Uye zvakare, iwe unogona kuwana thermocouples muchimiro chekushisa sensors mukicheni michina inoshandiswa mumahombe ekugadzira chikafu.
Thermocouples inoshandiswawo mumabikirwo edoro nekuti kugadzirwa kwedoro kunoda tembiricha chaiyo yekuvirisa kwakakodzera uye kudzivirira kusvibiswa kwehutachiona.
Kuyera kwakaringana tembiricha yesimbi yakanyungudutswa sesimbi, zingi uye aluminium inogona kunetsa nekuda kwekunyanya kupisa. Temperature sensors inowanzoshandiswa musimbi dzakanyungudutswa ndeye platinum thermocouples marudzi B, S uye R uye base metal thermocouples marudzi K uye N. Kusarudzwa kwemhando yakakodzera kunoenderana nekupisa kwehuwandu hwekushandiswa kwakananga kunobatanidza nesimbi.
Base metal thermocouples inowanzoshandisa US No. 8 kana No. 14 (AWG) wire geji ine simbi shield chubhu uye ceramic insulator. Platinum thermocouples, kune rumwe rutivi, inowanzo shandisa #20 kusvika #30 AWG madhayamita.
Kugadzirwa kwezvigadzirwa zvepurasitiki kunoda kunyatso kudzora tembiricha. Thermocouples inowanzodiwa pakudzora tembiricha munzvimbo dzakasiyana dzemapurasitiki kugadzirisa. Iwo anoshandiswa kuyera kunyungudika kana kupisa kwepasi mumajekiseni molds uye jekiseni molds.
Usati washandisa thermocouples mumapurasitiki ekugadzirisa, unofanirwa kuziva kuti kune marudzi maviri e thermocouples muindasitiri yepurasitiki. Chikamu chekutanga chinosanganisira kuyerwa. Pano, thermocouples inogona kushandiswa kuona kupisa kupisa basa remapurasitiki zvichienderana nechikamu chavo chemuchinjikwa. Rangarira kuti iyo thermocouple inofanirwa kuona mutsauko mukushandiswa kwesimba, kunyanya nekuda kwekumhanya kwayo uye kwainotungamira.
Iwe unogona zvakare kushandisa thermocouples mukuvandudza zvigadzirwa muindasitiri yepurasitiki. Nokudaro, rudzi rwechipiri rwekushandiswa kwe thermocouples muindasitiri yepurasitiki inosanganisira kugadzirwa kwechigadzirwa uye engineering. Mukuvandudzwa kwechigadzirwa, unofanirwa kushandisa thermocouples kuverenga shanduko yekushisa mumidziyo, kunyanya pamusoro pehupenyu hwechigadzirwa.
Mainjiniya vanogona kusarudza thermocouples inokodzera zvinhu zvavanoshandisa mukugadzira zvigadzirwa zvavo. Saizvozvo, vanogona kushandisa thermocouples kuyedza kuita kwedhizaini. Izvi zvinovabvumira kuita shanduko nzira yekugadzira isati yatanga.
Mamiriro echoto anonyanya kutarisisa yakakodzera thermocouple yehuni yekupisa yerabhoritari. Naizvozvo, kuti usarudze yakanakisa thermocouple, zvinhu zvakati wandei zvinofanirwa kutariswa, senge:
Muzviitiko zvakawanda, extruders inoda kudzvinyirira kwakanyanya uye kupisa kwakanyanya. Thermocouples ye extruder ine threaded adapters inobatsira kuisa matipi avo ekuongorora mupurasitiki yakanyungudutswa, kazhinji pasi pekumanikidzwa kwakanyanya.
Iwe unogona kugadzira idzi thermocouples sechinhu chimwe chete kana kaviri zvinhu zvine yakasarudzika yakarukwa dzimba. Bayonet thermocouples (BT) uye compression thermocouples (CF) anowanzo shandiswa mu low pressure extruder components.
Mhando dzakasiyana dze thermocouples dzine akawanda maapplication mumaindasitiri akasiyana. Saka kana iwe ukashanda muinjiniya, simbi, chikafu uye chinwiwa, kana mapurasitiki kugadzirisa, uchaona kuti thermocouples anoshandiswa zvakanyanya kuyera tembiricha uye kutonga.
