Kusetshenziswa kabanzi ezindaweni ezahlukahlukene ezenzakalelayo zezimboni, okubandakanya ukulondolozwa kwamanzi kanye ne-hydropower, ukuhanjiswa kwesitimela, izakhiwo ezihlakaniphile, ama-autosparation, ama-autosparical, amandla kagesi, imikhumbi, amathuluzi omshini, amapayipi kanye nezinye izimboni eziningi.
1.Isakhiwo sincane futhi sinhle, ukufakwa kulula, futhi kungafakwa ngqo
2.Ukuvikelwa Kokuxhumeka Kwasemuva
3.Ukuqina okuphezulu, ukunemba okuphezulu, izinga lokushisa elibanzi
4.Kunezinketho ezimbili zokuboniswa kwe-LED ne-LCD.
5.Ngaphansi kwezimo zokushisa eziphakeme, ukuphazamiseka kokuguqulwa imvamisa kuncane, ukuqina okuphezulu, nokuthembela okuphezulu
Isisekelo esiyinhloko sokukhethwa kwengcindezi / yokuhlukanisa ingcindezi yokudlulisela:Kususelwa kwizakhiwo ze-medium ezilinganisiwe, khetha imikhiqizo yokonga imali futhi kulula ukuyifaka.
Lapho ukhetha inzwa ye-diaphragm, kuyadingeka ukubheka ukugqwala kwe-sudium ephakathi nendawo ephakathi nendawo ye-diaphragm. Izinga le-diaphragm kumele lilunge, ngaphandle kwalokho i-diaphragm yangaphandle kanye ne-flange zizothuthukiswa ngemuva kwesikhathi sokusebenzisa, okungenzeka ukuthi kubangele izici noma izingozi zomuntu siqu. Ukukhetha kwe-Box Material kubaluleke kakhulu. I-diaphragm ye-transmitter yenziwa ngensimbi ejwayelekile, i-304 insimbi engenacala, 316 / 31l insimbi engagqwali, i-tantalum nokunye.
Ngaphezu kwalokho, izinga lokushisa lemiphakathi elinganiselwe lidinga ukubhekwa. Uma izinga lokushisa liphezulu, lifinyelela ku-200 ° C libe ku-400 ° C, uhlobo lokushisa oluphezulu kufanele lukhethwe, uma kungenjalo i-ailcone oyili izokhipha futhi yandise, yenza isilinganiso singenele.
Ukulinganiswa kwengcindezi okusebenzayo kwemishini nokulinganiselwa kwengcindezi ye-transmitter kumele kuhambisane nesicelo. Ngokombono wezomnotho, okuqukethwe kwebhokisi le-membrane yangaphandle kanye nengxenye yokufaka kubaluleke kakhulu, futhi kuyadingeka ukukhetha okulungile, kepha ukuxhumana kwe-flange kunganciphisa izidingo ze-carbon, njengokusebenzisa imali eningi.
Kungcono ukusebenzisa ukuxhumana okuhlanganisiwe kwama-transfitters angawodwa wokudlulisa, okugcina imali futhi kulula ukuyifaka.
Ukukhethwa kwengcindezi ejwayelekile kanye nengcindezelo ehlukile yokudlulisa, ukuwohloka kwendlela elinganiselwe kufanele futhi kubhekwe, kepha izinga lokushisa elisetshenziswayo lingaphendulwa, ngoba uhlobo olujwayelekile luyacindezelwa, kepha uhlobo olujwayelekile lusebenzisa ukulungiswa kwegumbi, kepha uhlobo olujwayelekile lusebenzisa ukunakekelwa okwengeziwe kunohlobo olulodwa. Owokuqala inkinga yokulondolozwa kokushisa. Lapho amazinga okushisa engaphansi kwe-zero, ishubhu eliqondisayo lokuqondisa lizoqina, futhi ukudlulisela ngeke kusebenze noma kulinyazwe. Lokhu kudinga ukungezwa kokuthathwa kokushisa kanye nokufakwa.
Ukusuka endaweni yezomnotho yokubuka, lapho ukhetha i-Transmitter, inqobo nje uma i-medium akulula ukuyisebenzisa, futhi i-pergitters ejwayelekile ingasetshenziswa, futhi i-purge medium nayo ingavumela ukusetshenziswa koketshezi noma igesi).Ama-transmitters ajwayelekile adinga abasebenzi bezokugcina ukuze bakwazi ukuqinisekisa ukuthi amapayipi ahlukahlukene wokuqondisa avuzayo, noma ngabe ukulondolozwa kokuhlanza kulungile, njll. Naka inhlanganisela yokulungiswa kwe-Hardware nokulungiswa okuthambile ngesikhathi sokulungiswa.
Ngokwesilinganiso uhla lokulinganisa, ngokuvamile i-transmitter inebanga oluthile olungaguquki, kungcono ukusetha uhla olusetshenzisiwe luye ku-1/4 ~ 3/4 lobubanzi bayo, ukuze ukunemba kwalo kuzoba qiniseka,Empeleni, ezinye izinhlelo zokusebenza (ukulinganiswa kwezinga le-liquid) kudingeka zihambisa uhla lokulinganisa lomhambisi. Uhla lokulinganisa kanye nenani lokufuduka kubalwa ngokuya ngesimo sokufaka esizeni sokufuduka. Ukufuduka kungahlukaniswa kube ukufuduka okuhle nokufuduka okubi. Njengamanje, ama-transmitters ahlakaniphile athandwa kakhulu. Ibonakala ngokunemba okuphezulu, ibanga elikhulu eliguqukayo, futhi ukulungiswa okulula nokuqina okuhle. Ukucatshangelwa okuningi kufanele kunikezwe ekukhetheni.
