Isicelo se-Micro Differential Pressure Sensor ku-HVAC

Izinzwa zokucindezela ezihlukile zisetshenziswa kabanzi kumapayipi kawoyela, ukulondolozwa kwamanzi kanye nama-hydrower, ukuthuthwa kwesitimela, Izakhiwo ezihlakaniphile, ukukhiqiza okuzenzakalelayo, i-aerospace, imboni yezempi, i-petrochemical, imithombo kawoyela, amandla kagesi, imikhumbi, Amathuluzi womshini, ukuphakelwa komoya kwamapayipi, ingcindezi emibi yokubilisa nezinye izimboni eziningi.

1. Inzwa yengcindezi ehlukile isetshenziselwa ukwakha okuzenzakalelayo.

Ubuchwepheshe be-automation yesimanje nobuchwepheshe be-HVACInzwa yengcindezi ehlukile hvacNgokuhlakanipha ngokufanisa ukukhiqizwa kwamandla, ukusatshalaliswa kwamandla, ukulungisa umoya nokululama kokushisa ukuqinisekisa ukuthi amandla asetshenziswa ngendlela yezinsizakusebenza nendlela esebenzayo.

LefooHlinzeka ngezixazululo zezinzwa ezisezingeni eliphakeme zokwakha amasistimu we-HVAC, kusuka ezinzwani ngazinye kuya kuzinhlelo eziyinkimbinkimbi zezinzwa eziqondene namakhasimende ezisiza ukuthuthukisa ukusebenza kahle kwamandla okushisa, izinhlelo zokungenisa umoya kanye nezinhlelo zomoya. Lefoo, chinaUmkhiqizi wokudlulisa ingcindeziInikeza ubuchwepheshe obuhlukahlukene benzwa yokukala izingcindezi ezincane zokuhlukanisa kubuchwepheshe besimo somoya kanye nokwakha okuzenzakalelayo.

2. Inzwa yengcindezi ehlukile isetshenziselwa ukulawulwa kwevolumu yomo

Izinhlelo ezihlukahlukene ze-Air Volume (VAV) ziyisixazululo esisebenzayo esinganciphisa izindleko zokutshalwa kwezimali eziyinhloko kanye nezindleko zokusebenza zabanikazi. Ukugcina amanani afanele angaphandle kokuncipha komoya, ukunyakaza komoya, nokusatshalaliswa komoya kuyizinselelo kubaklami be-VAV.

Ukuze kuqinisekiswe ukusakazwa komoya kwezitolo ezinkulu, izindawo ezingaphansi komhlaba nezakhiwo ezihlakaniphile, Ukulawulwa kwevolumu yomoya okuguqukayo kufanele kwenziwe. Umoya omkhulu uzochitha ugesi, futhi umoya omncane kakhulu uzothinta ukuphefumula kwabantu. Ngakho-ke, kuyadingeka ukulawula umthamo womoya ngokuqapha umfutho womoya.

3. Inzwa yengcindezi ehlukile isetshenziselwa ukuqapha isihlungi somoya ophakathi nendawo

Isihlungi somoya siyingxenye ebucayi yanoma yiluphi uhlelo lwe-HVAC, futhi sidinga ukusebenza kahle ngaso sonke isikhathi. Ngokusebenzisa izinzwa zokucindezela okuhlukile ukukala ingcindezi ngaphesheya kwesihlungi, uhlelo lwe-automation lwesakhiwo lungaqapha ukuhamba komoya ngaso sonke isikhathi.

Ukwehla kokuhamba komoya ngokuhamba kwesikhathi kungakhombisa ukuthi isihlungi sidinga ukushintshwa noma sihlanzwe. Uma kungashintshwa, uhlelo lungadinga ukusebenzisa amandla amaningi ukubuyisela ukugeleza komoya ezingeni elifunayo, okungabuye kwethule ukugqoka nokukhuba okwengeziwe kwezinye izinto ohlelweni.

4. Inzwa yengcindezi ehlukile isetshenziselwa ukulinganisa ukucindezela okumile kwepayibi

Izinzwa zokucindezela ezihlukile zidlala indima ebalulekile ekuhambiseni igesi yemvelo ngezinkulungwane zamapayipi wegesi yemvelo. Ingasetshenziselwa ukuqapha ingcindezi yegesi yemvelo, ilinganisa ukungena okuphansi kakhulu nezingcindezi ezingaphansi.

Izinketho ezikhethekile zokuvunywa ezifana ne-ATEX Intrinsic Safety ziyatholakala uma igesi yemvelo ingaba khona emkhathini wendawo. Uma ingcindezi yegesi emigqeni yegesi negesi iphakeme kakhulu, ukuvuza noma ngisho nokuqhuma kungenzeka. Uma ingcindezi yomoya iphansi kakhulu, izothinta ukusetshenziswa kwabantu kwansuku zonke, ngakho-ke kuyadingeka ukuqapha ingcindezi yomoya ye-node ngayinye ngokudlaInzwa yokucindezela ehlukileUkuze ingcindezi yomoya ingaphakathi kwebanga elifanele.

5. Inzwa yengcindezi ehlukile isetshenziselwa ukucindezelwa kwehhavini kanye nokulawulwa kwengcindezi yomoya kwamatho

Inzwa yengcindezi ehlukile iqinisekisa ukulawulwa kwengcindezi yomoya ehhavini ngokuthola nokulawula ingcindezi yomoya kuyo iphuzu ngalinye esiteshini sokuhlinzeka komoya kanye nengcindezi engemihle endaweni ngayinye esiteshini sokufakwa komoya. Ukulawula ingcindezi embi yesithando somlilo kanye nengcindezi ehlukile yevolumu yomoya yokuhlinzeka kungaqinisekisa ukushiswa kukaphethiloli okusebenzayo futhi ukuvikelwa kwemvelo. Ngenxa yemithethonqubo yezemvelo kanye nezingozi zokuphepha, ama-boilers adinga ukuqapha uhlelo olunembile nokwethenjelwa ukuthuthukisa ukusebenza kahle nokuvimbela ukwehluleka ngaphambi kwesikhathi.
