The differential pressure switch is a special pressure control switch, iyo yakavakirwa pamusiyano wekumanikidzana pakati pezvikamu zvakasiyana-siyana, uye inotumira ruzivo kuburikidza nemagetsi masaini kudzora kuvhara kana kuvhurwa kwe switch. The valve body of differential pressure switch uye kufamba. switch inounganidzwa pandiro yepasi. Pasi pechiito chekumanikidza, girisi inopinda mugomba rekurudyi rekusiyanisa kudzvanya vheji yemuviri piston kubva papombi huru B, uye pombi huru A inodururwa.Kana mutsauko wepakati pakati pemapaipi makuru maviri unosvika pakukosha kwakaiswa, piston. inokunda simba rechitubu mugomba rekuruboshwe uye inofamba kuruboshwe, uye inosundira chinja chekufamba kuti ivhare kuonana, uye inotumira chiratidzo chepulse kune system yemagetsi control box kuti iraire reversing valve kuti ichinje nzira.Panguva ino, iyo huru pombi A inodzvanywa, uye B inoburitswa. Iyo piston yakatarisana pasi pechiito chechirimo mune maviri-magumo mhango, iyo sitiroko switch maconta 1 uye 2 yakabviswa, uye bhiriji rekusangana riri munzvimbo isina kwayakarerekera.
Iyo system inotanga kutenderera kwechipiri. Kamwe mutsauko wekumanikidza pakati pepombi huru A uye B inosvika pakukosha kwakaiswa zvakare, piston inofamba ichienda kurudyi, sitiroko chinja macontact 3 ne4 anovharwa, uye pulse siginecha zvakare inoita kuti vheji inodzosera muhurongwa ichinje nzira. Tanga denderedzwa rinotevera rebasa.
The differential pressure switch inogona kushandiswa zvakanyanya muhombe, yepakati uye diki mhepo-yakatonhorera kana mvura-yakatonhodzwa chillers vachishandisa ndiro kupisa exchangers, chubhu kupisa exchangers uye goko uye chubhu kupisa exchangers kuti mvura kuyerera uye pombi mvura uye mvura sefa mamiriro monitoring. inoshandiswawo mukuona gasi, kusaodza midhiya, chiyero chekumanikidza, gauge pressure, uye inoshandiswa zvakanyanya mumhepo inofefetera uye mukamuri yakachena, feni uye kusefa kufefetera, kudzora kwemvura uye mvura.
Iko kushandiswa kwekusiyanisa kudzvanywa kwekuchinja muHVAC system kunonyanya kudzorwa zvichienderana nekupokana uye kuyerera curve yeHVAC midziyo, iyo yemvura padivi kupisa kupisa muHVAC (tube-in-tube type, shell-and-tube type, chubhu. -plate type uye inowanzo shandiswa ndiro heat exchanger) , Mafirita emvura, mavharuvhu nemapombi ane kudonhedza kwadzo uye kuyerera kwekuita curves. Chero bedzi iyo yakayerwa kudzvanywa musiyano pamativi ese ekumanikidza musiyano switch inofananidzwa neiyo preset kukosha, kuyerera kunogona kudzorwa nemazvo.
