Siyini Isakhiwo Senzwa Yokushisa Ephezulu Nomswakama?

Izinzwa zokushisa eziphezulu kanye nomswakamazivame ukusetshenziswa ekwelapheni amanzi.Isici sesihlungi se-resin wuhlobo lwezinto ezihlanzekile zamanzi ezenziwe ngokucubungula okwenziwe.Ivame ukusetshenziswa emanzini okuphuza kanye nokuhlunga amanzi ahlanzekile.Njengomkhiqizo wokuhlunga, isici sokuhlunga sisetshenziswa kakhulu ezindaweni ezihlukahlukene zezimboni.Izakhi zokuhlunga zezinto ezihlukene zijwayele izidingo ezihlukene zobungcweti, futhi ukuthengwa nokusetshenziswa kwezinto zokuhlunga kusazokhetha imikhiqizo efanelekile ngokusekelwe ezidingweni zabo.

I. Isingeniso

Izinga lokushisa kanye nomswakama yizici ezimbili ezibaluleke kakhulu zemvelo okufanele ziqashwe ezimbonini ezihlukahlukene kanye nezinhlelo zokusebenza.Izinzwa zokushisa eziphezulu nezomswakama zisetshenziselwa ukukala le mingcele ukuze kuqinisekiswe ukuphepha, ukuthuthukisa ukusebenza kahle, nokuthuthukisa izinqubo.Lokhu okuthunyelwe kwebhulogi kuzoxoxa ngesakhiwo sezinzwa zokushisa eziphezulu kanye nomswakamo, okuhlanganisa izinhlobo nezingxenye ezahlukene kanye nendlela ezisebenza ngayo.

II.Izinhlobo Zezinzwa Zezinga Lokushisa Eziphezulu Nomswakama

Izinhlobo ezimbalwa zezinzwa zokushisa okuphezulu kanye nomswakama ziyatholakala, ngayinye enezici ezihlukile kanye nezinzuzo.Izinhlobo ezisetshenziswa kakhulu zihlanganisa:

1.Izihloli Zezinga Lokushisa Ezimelana Nokumelana (ama-RTD):

Lezi zinzwa zisebenzisa ukuguqulwa kokumelana kwento ethile ukukala izinga lokushisa.Zinembe kakhulu futhi zinezinga lokushisa elibanzi, kodwa futhi zibiza kakhulu futhi zintekenteke.

2.Ama-Thermocouples:

Lezi zinzwa zisebenzisa umehluko ongaba khona kagesi phakathi kwezinsimbi ezimbili ezingafani ukukala izinga lokushisa.Ashibhile futhi aqinile kodwa anembe kancane kunama-RTD futhi anebanga lokushisa elilinganiselwe.

3. Ama-thermistors:

Lezi zinzwa zisebenzisa ukuguqulwa kokumelana kwezinto ze-semiconductor ukukala izinga lokushisa.Mancane futhi awabizi kodwa anembe kancane kunama-RTD futhi anebanga lokushisa elilinganiselwe.

Mayelana nomswakamo, kukhona izinzwa ezimbalwa, ezifana ne-capacitive, resistive, ne-optical.Ngayinye yazo inezinzuzo zayo kanye nebubi.

III.Izingxenye Zenzwa Yokushisa Ephezulu Nomswakama

Isakhiwo senzwa yokushisa ephezulu kanye nomswakamo ngokuvamile sihlanganisa izingxenye ezimbalwa ezibalulekile:

• Isici sokuzwa: Lena ingxenye yenzwa ekala izinga lokushisa nomswakama.Ingenziwa ngezinto ezihlukahlukene, kuye ngohlobo lwenzwa.
• I-conditioner yesignali: Le ngxenye iguqula isignali kagesi isuka kusici senzwa ibe ifomu elingadluliswa futhi lifundwe ngamanye amadivaysi.
• I-transmitter: Le ngxenye idlulisela isignali isuka kunzwa iye ohlelweni lokuqapha noma lokulawula olukude.
• Isibonisi noma idivayisi ephumayo: Le ngxenye ibonisa izinga lokushisa nokufundwa komswakamo, ngokuvamile i-analog noma ukufundwa kwedijithali.

IV.Zisebenza Kanjani Izinzwa Zezinga Lokushisa Eziphezulu Nomswakama

Ukusebenza kwenzwa yokushisa ephezulu kanye nomswakama kuncike ohlotsheni lwenzwa esetshenzisiwe.Ngokuvamile, isici sokuzwa senzwa sizosabela ekushintsheni kwezinga lokushisa nomswakama ngokushintsha izici zayo zikagesi.I-conditioner yesignali ibe isiguqula lolu shintsho ezimpahleni zikagesi lube isignali efundekayo.Umthumeli ube esethumela lesi siginali kusistimu yokuqapha noma yokulawula eyirimothi, lapho ukufundwa kwezinga lokushisa nokuswakama kungaboniswa noma kusetshenziselwe ukulawula amanye amadivaysi.

Ukulinganisa kuyisinyathelo esibalulekile kule nqubo, futhi kuwukuqinisekisa ukuthi inzwa ikala ngokunembile izinga lokushisa noma umswakama.Ingakwenza ngokuqhathanisa ukufundwa kwenzwa nezinga elaziwayo noma isebenzisa idivayisi yokulinganisa.

V. Ukusetshenziswa Kwezinzwa Zokushisa Eziphezulu Nomswakama

Izinzwa zokushisa eziphezulu kanye nomswakama zinezinhlelo zokusebenza ezihlukahlukene kuzo zonke izimboni nezindawo ezihlukahlukene.Ezinye izibonelo zihlanganisa:

• Izilungiselelo zezimboni: Izinzwa zokushisa eziphezulu kanye nomswakamo, njengokuqapha isithando somlilo, zisetshenziswa ezinqubweni zokukhiqiza ukuze kuqinisekiswe ukuthi amazinga okushisa nokuswakama angaphakathi kwemikhawulo ephephile.
• Amasistimu e-HVAC: Lezi zinzwa zisetshenziswa ezinhlelweni zokushisisa, zokungenisa umoya, nezokupholisa umoya ukuze kuqashwe futhi kulawuleke izinga lokushisa kanye nokuswakama kwezakhiwo nezinye izakhiwo.
• Ukuqapha isimo sezulu: Izinzwa zokushisa eziphezulu kanye nomswakamo zisetshenziswa eziteshini zesimo sezulu ukukala izinga lokushisa kanye nomswakama womoya.
• Ezolimo:Lezi zinzwa zisetshenziswa ezindaweni zokugcina izithombo nakwezinye izilungiselelo zezolimo ukuze kuqashwe futhi kulawule izinga lokushisa kanye nomswakama ukuze kuthuthukiswe ukukhula kwezitshalo nokunciphisa ukulahleka kwezitshalo.

VI.Isiphetho

Izinzwa zokushisa eziphezulu kanye nomswakama zibalulekile ekuqapheni nasekulawuleni izinga lokushisa kanye nomswakama ezimbonini ezihlukahlukene kanye nezinhlelo zokusebenza.

Izinhlobo eziningana zezinzwa ziyatholakala, ngayinye inezici ezihlukile kanye nezinzuzo.Isakhiwo senzwa yokushisa ephezulu kanye nomswakamo ngokuvamile sihlanganisa into yokuzwa, isibandisi sesignali, isidluliseli, nesibonisi noma idivayisi ephumayo.

Ukusebenza kwalezi zinzwa kuncike ohlotsheni lwenzwa esetshenzisiwe futhi iyalinganiswa ukuze kuqinisekiswe ukunemba.Izinzwa zokushisa eziphezulu nezomswakama zinezinhlobonhlobo zezinhlelo zokusebenza, kusukela kuzilungiselelo zezimboni kuya ekuqaphelweni kwesimo sezulu kanye nezolimo.Njengoba ubuchwepheshe buthuthuka, ukunemba kanye nekhono lalezi zinzwa kuthuthuka ngokuqhubekayo, okuzenza zibe ithuluzi elibalulekile lokuqinisekisa ukuphepha, ukuthuthukisa ukusebenza kahle, kanye nezinqubo zokuthuthukisa.

Ukukhetha umumo wedivayisi ofanele kubaluleke kakhulu ukuze uqinisekise ukunemba okungcono kakhulu nesivinini sokuphendula futhi uvikele inzwa emonakalweni.Ngokwezidingo zendawo yakho yokulinganisa, linganisa idivayisi yenzwa yephoyinti lamazolo ngommo ongaguquki, njengalapho idivayisi is emnyango wekhabhinethi, izilinganiso zenzwa yamazolo Yindawo yamazolo yegesi lapho ingena ebhokisini, igesi ngaphakathi kwebhokisi ngokwalo noma yimuphi umswakama owenzeka ngesikhathi somsebenzi ngeke ubonakale.

Lapho i-i-dew point transmitteridivayisi isendaweni yokukhipha igesi, inzwa izokala umswakama ongena ohlelweni nge-inlet noma ukuvuza kanye nomswakama okhululwa ngesikhathi somsebenzi.HENGKOI-HT608 yochungechunge lwenzwa/i-transmitter yamazolobabe nenzuzo yokunemba okuphezulu, ukusetshenziswa kwamandla okuphansi nokuvumelana okuhle.
