I-valve yokuzilawula ye-ZDT Model Automatic
Uchungechunge lwe-ZDT i-Automstic recirculation valve luhlobo lwedivayisi yokuvikela iphampu. It ukuvikela othomathikhi futha centrifugal lapho futha umzimba kwenzeka umonakalo cavitation noma engazinzile (ikakhulukazi ehambisa amanzi ashisayo at low umthwalo operation). Lapho ukugeleza kwepompo sekuphansi kunokugeleza okuhleliwe, ukudlula kungavuleka ngokuphelele ukuqinisekisa ukuthi iphampu yokugeleza edingekayo ubuncane. Noma kusebenza kuvalwe ngokuphelele, okungukuthi ukugeleza okuyinhloko zero, ukugeleza okuncane nakho kungakhipha ngokudlula.
Uchungechunge lwe-ZDT lunokudlula okukhulu, futhi le valve ilungele ukudlula ngokugeleza okukhulu, umehluko omkhulu wokucindezela yi-4MPa, ukukhetha okuthile kunqunywa yifektri.
• Isakhiwo esilula, ukusebenza okuthembekile nokuzinzile, kunezingxenye ezimbalwa zokuhamba.
• Yiba lula ukufakwa, ingafakwa ngokuma noma ngokuvundlile ekuphumeni kwepompo.
• Ukuhamba kwe-Bypass kukhulu, ukugeleza okuphezulu kungama-60% wokugeleza okuyinhloko, i-valve ye-KV ingalungiswa.
• Ukwahlukaniswa okuphezulu kwengcindezi yokusebenza yi-4MPa. Umsebenzi we-Bypass non-return ungakhethwa.
• Isetshenziswa esiphakathi nendawo okubandakanya: amanzi, uwoyela, i-methanol nokunye oketshezi.
• Ukushisa okusebenzayo: -196 ℃ to + 130 ℃.
Uhlobo lomzimba we-Valve: izindlela ezintathu zokuphonsa i-valve
Ububanzi bokuqokwa: NPS1 "-16" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400)
Ukucindezela okuzenzakalelayo: CL150 # -400 # (PN16, 25, 40, 64)
Qeda uhlobo loxhumano: Flange FF, RF, RTJ, BW, SW, njll.
Ngokuya ngokwehluka kokugeleza okuyinhloko, i-valve eyinhloko yediski yokuhlola ye-valve ezenzakalelayo yokubuyela emuva izohamba ngokuzenzakalela iye endaweni ethile. Ngasikhathi sinye i-valve enkulu yedrayivu idlula isiqu se-valve, dlulisa ukuhamba kwediski enkulu ye-valve ukudlula, ngokulawula indawo yediski ye-valve, shintsha indawo yokudlula, ukuze ulawule ukugeleza kokudlula. Lapho idiski enkulu ye-valve ibuyela esihlalweni se-valve ivaliwe, konke ukugeleza kubuyela emuva ngokudlula. Lapho i-valve enkulu disc ikhuphukela endaweni ephezulu, ukudlula kuvaliwe ngokuphelele, konke ukugeleza kokugeleza kwepompo kucubungula uhlelo. Le valve ibeka imisebenzi emine emzimbeni owodwa.
• Umbono wokugeleza: I-disc disc ye-valve eyinhloko yokubona okuzenzakalelayo ingabona ngokuzenzakalela ukugeleza okuyisisekelo kohlelo lwenqubo, ngaleyo ndlela ngokuya kokugeleza ukuthola indawo yediski enkulu ye-valve nokudlula idiski.
• Ukulawulwa kwe-recirculation: I-valve yokuphindisela okuzenzakalelayo ingadonsa futha ukusebenza okujwayelekile okudingekayo ukugeleza okuncane okungena kudivayisi yokugcina ngokudlula, ukuze kulungiswe iphampu ye-HQ charateristics, ukubona kabusha.
• Hlola i-valve: I-valve yokuphindaphinda okuzenzakalelayo nayo inomphumela we-valve yokuhlola, ukuvimbela ukubuyela emuva kuketshezi ukupompa umzimba. Umsebenzi we-Bypass non-return ungakhethwa.
• Usayizi okhethekile wokudlula ungenziwa ngezifiso. Izinga lokugeleza okukhulu lingaphansi kwenani le-max Kv.
