Inzwa yokucindezela kawoyela 161-1705-07 ye-cat excavator E330C

isimiso sokusebenza

Inzwa yakhelwe kumgomo wokunwetshwa kwensimbi

inzwa yokushisa

inzwa yokushisa

Insimbi izokhiqiza isandiso esihambisanayo ngemuva kokushintsha kwezinga lokushisa kwemvelo, ngakho-ke inzwa ingaguqula isignali yalokhu kusabela ngezindlela ezahlukene.eziyisithupha

Inzwa ye-Bimetallic chip

Ishidi le-Bimetallic liqukethe izingcezu ezimbili zensimbi ezinama-coefficients ahlukene okunweba ahlanganiswe ndawonye.Ngokushintsha kwezinga lokushisa, izinga lokunwetshwa kwezinto A liphakeme kunelinye insimbi, okwenza ishidi lensimbi ligobe.Ijika lokugoba lingaguqulwa libe isignali yokuphumayo.

I-Bimetal rod kanye nenzwa yeshubhu yensimbi

Ngokukhuphuka kwezinga lokushisa, ubude be-tube yensimbi (i-material A) buyanda, kodwa ubude bensimbi enganwetshiwe (insimbi B) ayenzi, ngakho-ke ukunwetshwa komugqa we-tube yensimbi kungadluliselwa ngenxa yokushintsha kwesimo.Ngokulandelayo, lokhu kunwetshwa komugqa kungaguqulwa kube isignali yokuphumayo.

Inzwa yokwakheka kwejika le-deformation loketshezi negesi

Lapho izinga lokushisa lishintsha, umthamo woketshezi negesi nawo uzoshintsha ngokufanele.

Izinhlobo ezehlukene zezakhiwo zingaguqula lolu shintsho lokunwetshwa lube uguquko lwendawo, ngaleyo ndlela lukhiqize ukuphuma kokushintsha kwesimo (i-potentiometer, ukuchezuka okudalwe, i-baffle, njll.).

Inzwa yokumelana

Ngokushintsha kwezinga lokushisa, inani lokumelana lensimbi nalo liyashintsha.

Ezinsimbi ezahlukene, ukuguqulwa kwenani lokumelana kuhlukile njalo lapho izinga lokushisa lishintsha ngedigri eyodwa, futhi inani lokumelana lingasetshenziswa ngokuqondile njengesignali yokuphumayo.

Kunezinhlobo ezimbili zezinguquko zokumelana.

I-coefficient yezinga lokushisa elihle

Ukukhuphuka kwezinga lokushisa = ukwanda kokumelana

Ukwehla kwezinga lokushisa = ukwehla kokumelana.

I-coefficient yezinga lokushisa elingalungile

Izinga lokushisa liyakhuphuka = ​​ukumelana kuncipha.

Izinga lokushisa liyehla = ukumelana kuyanda.

Inzwa ye-Thermocouple

I-thermocouple iqukethe izintambo ezimbili zensimbi zezinto ezahlukene, ezishiselwe ndawonye ekugcineni.Ngokulinganisa izinga lokushisa elizungezile lengxenye engashisi, izinga lokushisa lendawo yokushisa lingaziwa ngokunembile.Ngenxa yokuthi kufanele ibe nama-conductor amabili ezinto ezahlukene, ibizwa ngokuthi i-thermocouple.Ama-thermocouples enziwe ngezinto ezahlukene asetshenziswa emazingeni okushisa ahlukene, futhi ukuzwela kwawo kuhlukile.Ukuzwela kwe-thermocouple kubhekisela ekushintsheni komehluko ongaba khona lapho izinga lokushisa lishintsha ngo-1℃.Kuma-thermocouple amaningi asekelwa izinto zensimbi, leli nani licishe libe ngu-5 ~ 40 microvolts/℃.

Ngenxa yokuthi ukuzwela kwenzwa yokushisa ye-thermocouple akuhlangene nobukhulu bezinto ezibonakalayo, kungenziwa futhi ngezinto ezinhle kakhulu.Futhi, ngenxa ye-ductility enhle yezinto zensimbi ezisetshenziselwa ukwenza i-thermocouple, le nto encane yokulinganisa izinga lokushisa inejubane eliphezulu kakhulu lokuphendula futhi ingakala inqubo yoshintsho olusheshayo.
