ZDM mndandanda Automatic recirculation valavu ndi mtundu wa chipangizo chitetezo mpope. Iwo basi amateteza centrifugal mpope pamene mpope thupi zimachitika cavitation zowonongeka kapena kusakhazikika (makamaka kunyamula madzi otentha pa otsika katundu ntchito). Kuthamanga kwa pampu kukakhala kocheperako kuposa momwe adakhazikitsira, bypass imatha kutseguka kuti iwonetsetse kuti pampu yoyenda ikufunika. Ngakhale kuthamanga kutsekedwa kwathunthu, ndiko kuti kuthamanga ndi zero, kuyenda kochepa kumatha kudutsanso kuti Automatic recirculation. Kupanikizika kumachepetsedwa kudzera mu multistage bypass pressure reduction valve.

Mndandanda wa ZDM ndi woyenera kulambalala ndi kusiyanitsa kwakukulu, kusiyana kwakukulu ndi 30MPa, ndipo kusankha kwapadera kumatsimikiziridwa ndi fakitale. Multistage decompression mtundu wa M mtundu wodutsa umatha kuthetsa phokoso lopangidwa ndi sing'anga yothamanga kwambiri, kuteteza kuwonongeka kwa kukokoloka kwa cavitation ndi braising ku zigawo za valve.

Makhalidwe

• Pewani cavitation multistage decompression bypass, kuchepetsa kuthamanga, koyenera kupanikizika kwambiri.

• Thupi lopangidwa ndi valve, kapena mungasankhe zitsulo za carbon kapena zitsulo zosapanga dzimbiri, etc.

• Standard bypass ntchito yosabwerera, kusiyana kwakukulu kogwira ntchito ndi 30MPa.

• Pressure grade kuchokera ku PN16 kupita ku PN420, m'mimba mwake kuchokera ku DN2 mpaka DN500.

• Mutha kusankha ntchito yolambalala yamanja, yogwiritsidwa ntchito molakwika.

Kukula ndi kupanikizika osiyanasiyana

Mtundu wa thupi la vavu: Vavu yopangira njira zitatu
M'mimba mwake mwadzina: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)
Kupanikizika mwadzina: CL150#-2500# (PN16, 25, 40, 64, 100, 160, 250, 420)
Mapeto kugwirizana mtundu: Flange, FF, RF, RTJ, BW, SW etc.

Mfundo yogwira ntchito

Malingana ndi kusiyana kwa kutuluka kwakukulu kwa inductive, valavu yayikulu yoyang'ana valavu yodziwikiratu imasunthira kumalo enaake. Panthawi imodzimodziyo, tsinde la valve disk drive bypass valve, sinthani kayendedwe ka valve yaikulu kuti idutse, kupyolera mu ulamuliro wa bypass valve disc, kusintha malo ozungulira, kuti muwongolere kutuluka. Pamene valavu yayikulu imabwerera kumpando wa valve yatsekedwa, zonse zimabwerera mmbuyo kupyolera mu bypass. Pamene chimbale chachikulu cha vavu chikwera pamwamba, chodutsacho chimatsekedwa kwathunthu, kutuluka konse kwa mpope kupita ku dongosolo. Vavu iyi imayika ntchito zinayi m'thupi limodzi.

• Lingaliro lakuyenda: Ma valve main valve disc amatha kuzindikira momwe kayendedwe ka kayendedwe kake kamayendera, potero molingana ndi kayendedwe kake kuti adziwe malo a valavu yayikulu ndi disc disc.
• Kuwongoleranso: Vavu yodziyimira payokha imatha kutulutsa mpope momwe ntchito yanthawi zonse imafunikira kuyenda pang'onopang'ono mu chipangizo chosungiramo kudzera panjira yodutsa, kuti musinthe mawonekedwe a pampu ya HQ, kuti azindikire kubwezeretsanso.
• Bypass multistage pressure kuchepetsa: bypass control system ingachepetse kubweza kwapakati kuchokera ku pompu yopopera yothamanga kwambiri kupita kumayendedwe oyenera kupita ku chipangizo chosungirako chocheperako chokhala ndi phokoso laling'ono.
• Yang'anani: Valavu yodziwikiratu yokha ilinso ndi mawonekedwe a valavu, kuletsa kutuluka kwamadzi kuti kumapope thupi. Bypass osabwerera ntchito ndi muyezo.
• Special kulambalala kukula akhoza makonda. Kuthamanga kwakukulu kodutsa kumatengera Kv mtengo.
