ZDL mndandanda Auromatic recirculation valavu ndi mtundu wa mpope prtectiong chipangizo. Iwo basi amateteza centrifugal mpope pamene mpope thupi zimachitika cavitation kuwonongeka 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. ZDL mndandanda ndi woyenera kulambalala ndi sing'anga kapena otsika kuthamanga kusiyana, pazipita kuthamanga kusiyana ndi 6MPa, ndi kusankha mwachindunji ndi fakitale. Unique L bypass imatha kuthetsa phokoso pogwiritsa ntchito sing'anga yothamanga kwambiri, komanso cavitation yaposachedwa.

Makhalidwe

• Mipikisano khola mtundu bypass, otsika phokoso, oyenera sing'anga ndi otsika kupanikizika ntchito zikhalidwe.

• Thupi la valve lopangidwa, lingasankhe zitsulo za carbon kapena zitsulo zosapanga dzimbiri, etc.

• Standard bypass non-return fuction, pazipita ntchito kusiyana ndi 6MPa.

• Ndi venturi port main otaya mawonekedwe osabwerera, sinthani ndi zovuta.

• Pressure grade kuyambira PN16 mpaka PN100, 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: Thupi lopangidwa mwanjira zitatu.

M'mimba mwake mwadzina: NPS1"-20" (DN25, 32, 40, 50, 65, 80, 100, 200, 250, 300, 350, 400, 450, 500)

Kupanikizika mwadzina: CL150#-600# (PN16, 25, 40, 64, 100)

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. Ntchito yosabwereranso yobweza ndiyosasankha.
• Special kulambalala kukula akhoza makonda. Kuthamanga kwakukulu kodutsa kumatengera Kv mtengo.
