Yiziphi izindlela zokulawula ze-thermostat?
Kunezindlela ezimbili eziyinhloko zokulawula i-thermostat: i-ON/OFF control kanye ne-PID control.
Ukulawula kwe-1.ON/OFF kuyimodi yokulawula elula, enezimo ezimbili kuphela: ON kanye ne-OFF. Uma izinga lokushisa elibekiwe liphansi kunezinga lokushisa elibekiwe, i-thermostat izokhipha isignali ye-ON ukuze iqale ukushisa; Uma izinga lokushisa elibekiwe liphezulu kunezinga lokushisa elibekiwe, i-thermostat izokhipha isignali ye-OFF ukuze iyeke ukushisa. Nakuba le ndlela yokulawula ilula, izinga lokushisa lizoshintshashintsha lizungeze inani elibekiwe futhi alikwazi ukuzinza ngenani elibekiwe. Ngakho-ke, lifaneleka ngezikhathi lapho ukunemba kokulawula kungadingeki khona.
2. Ukulawula i-PID kuyindlela yokulawula ethuthuke kakhulu. Ihlanganisa izinzuzo zokulawula okulinganayo, ukulawula okuhlanganisiwe kanye nokulawula okuhlukile, futhi ilungisa futhi ithuthukise ngokwezidingo zangempela. Ngokuhlanganisa izilawuli ezilinganayo, ezihlanganisiwe, kanye nezihlukile, abalawuli be-PID bangasabela ngokushesha ekushintsheni kwezinga lokushisa, balungise ngokuzenzakalelayo ukuphambuka, futhi banikeze ukusebenza okungcono kwesimo esizinzile. Ngakho-ke, ukulawula i-PID kuye kwasetshenziswa kabanzi ezinhlelweni eziningi zokulawula zezimboni.
Kunezindlela eziningi zokukhipha i-thermostat, ikakhulukazi kuye ngendawo yayo yokulawula kanye nezici zemishini yokulawula oyifunayo. Nazi ezinye zezindlela zokukhipha i-thermostat ezivame ukusetshenziswa:
Ukukhishwa kwe-voltage: Lena enye yezindlela ezivame kakhulu zokukhipha ukulawula isimo sokusebenza sedivayisi ngokulungisa ubukhulu besignali ye-voltage. Ngokuvamile, i-0V ikhombisa ukuthi isignali yokulawula icishiwe, kanti i-10V noma i-5V ikhombisa ukuthi isignali yokulawula ivuliwe ngokuphelele, lapho idivayisi elawulwayo iqala ukusebenza. Le modi yokukhipha ifanelekela ukulawula ama-motor, amafeni, izibani namanye amadivayisi adinga ukulawulwa okuqhubekayo.
Ukukhishwa kwe-relay: Ngokusebenzisa isignali yokushintsha i-relay yokuvula nokuvala kuya ekulawuleni izinga lokushisa lokukhipha. Le ndlela ivame ukusetshenziselwa ukulawula ngqo imithwalo engaphansi kuka-5A, noma ukulawula ngqo ama-contactor nama-relay aphakathi, kanye nokulawula kwangaphandle kwemithwalo enamandla aphezulu ngama-contactor.
Ukukhishwa kwe-voltage yedrayivu ye-relay yesimo esiqinile: Shayela ukukhishwa kwe-relay yesimo esiqinile ngesignali ye-voltage yokukhipha.
I-relay yesimo esiqinile iqhuba ukuphuma kwe-voltage.
Ngaphezu kwalokho, kunezinye izindlela zokukhipha, njengokukhipha kokulawula i-trigger yesigaba se-thyristor, ukuphuma kwe-trigger ye-thyristor zero kanye nokukhipha kwesignali okuqhubekayo noma kwamanje. Lezi zindlela zokukhipha zifanelekela izindawo ezahlukene zokulawula kanye nezidingo zedivayisi.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
