Hydraulic inodzorwa inononoka kuvhara cheki butterfly vharafu ndeye yepamusoro pombi yekudzora midziyo kumba nekune dzimwe nyika. Iyo inonyanya kuiswa pane turbine inlet yehydropower station uye inoshandiswa se turbine inlet valve; Kana kuiswa munzvimbo yekuchengetedza mvura, simba remagetsi, mvura yekupa uye kubuda kwepombi yemvura, pane cheki chevhavha uye gedhi valve. Kana ichishanda, vharafu inobatira pamwe neinjini huru yepombi, zvinoenderana nemusimboti wehydraulic transition process, uye kuburikidza neyakagadzikwa yekuvhura nekuvhara maitiro, inogona kuona yakavimbika yekucheka-kubviswa kwepombi, kunyatsobvisa nyundo yemvura mupombi, uye kuita basa mukuchengetedza kuchengetedzwa kwepombi system.

Kushanda musimboti

The reserved kuvhara simba reheavy sando hydraulic control inononoka kuvhara cheki butterfly vharafu inorema nyundo inogona simba, iyo yakakamurwa kuita inorema nyundo otomatiki kumanikidza kuchengetedza hydraulic control inononoka kuvhara cheki butterfly vharafu (inozonzi inorema nyundo kumanikidza kuchengetedza mhando) uye kukiya inorema sando otomatiki kudzvanya kuchengetedza hydraulic control inononoka kuvhara cheki butterfly vharafu seanorema locking vharuvhu (heavy locking). Mamiriro ebasa anonyanya kusanganisira centrifugal pombi mamiriro, axial kuyerera pombi mamiriro uye turbine mamiriro.

Mamiriro ekushanda epombi ye centrifugal ine vharafu yekuvhura (kusanganisira centrifugal yakasanganiswa inoyerera pombi): tanga pombi kutanga, uye vhura vharafu mushure mekunonoka nguva yakarongwa.

Mamiriro ekushanda evharuvhu yakavhurika axial flow pump (kusanganisira axial yakasanganiswa inoyerera pombi): vhura vharafu yepombi panguva imwe chete, kana kuvhura vharafu kune imwe kona kutanga, uye wozotanga pombi.

Mamiriro ekushanda evhavha yekuvhura turbine: tanga wavhura iyo bypass valve kuti uenzanise kudzvanywa, wozovhura vharuvhu, wozovhura turbine.

Zvinowanzodiwa kuvhara valve panguva imwechete yekuvhara kana kuparara kwesimba pasi pemamiriro akasiyana-siyana ekushanda.

Iyo yakakosha electro-hydraulic kushanda musimboti ndeiyi inotevera:

Pakuvhura vharuvhu, solenoid valve inodzokera kumashure, pombi yeoiri inotanga, uye mafuta ehydraulic anopinda mucylinder yeoiri kuburikidza nevharuvhu yekudzora kuyerera uye high-pressure hose yekusundira piston uye kutyaira iyo lever yakabatana nayo kusimudza inorema sando kuvhura vharafu. Mushure mokunge vharuvhu yakavhurwa panzvimbo, iyo otomatiki yekumanikidza kuchengetedza system inotanga; Iyo mota inoramba ichichaja iyo accumulator. Kana dzvinyiriro ichisvika padanho repamusoro-soro, pombi yemafuta inomira. Iyo nguva yekuvhura yevhavha inogona kugadziriswa nekutenderera ruoko rwevhavha yekudzora kuyerera, uye chiyero chekugadzirisa ndeye 10 ~ 90 masekondi.

Kana sisitimu ichidonhedza uye kudzvinyirirwa kunodonhera kune yakaderera pressure set point, mota yepombi yemafuta inotanga otomatiki uye inomira mushure mekunge yasvika padanho repamusoro.

Pakuvhara valve, iyo solenoid valve inodzokera shure, mafuta ekumanikidza muvhavha yemafuta anodzokera kune tangi yemafuta kuburikidza nekutsanya uye zvishoma nezvishoma kuyerera kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha, high-pressure hose uye solenoid valve, nyundo inorema inowira pasi, uye tsvimbo yekubatanidza inotyaira ndiro ye butterfly kutenderera kuvhara valve, kuitira kuti ikurumidze kugura yakawanda yemvura inoyerera inenge 70% yemvura yapfuura; Iyo yekupedzisira 30% yekurohwa inovharwa zvishoma nezvishoma. Iko kona yekukurumidza uye kunonoka kuvhara uye nguva yebuffer yechikamu chimwe nechimwe inogona kugadziriswa maererano nemamiriro chaiwo ekushanda kwepombi kuti ibudirire kubvisa nyundo yemvura mupombi; Nguva yekugadzirisa ndeye 2 seconds kusvika ku25 seconds yekuvhara nekukurumidza uye 6 seconds kusvika 90 seconds yekuvhara zvishoma nezvishoma.

Mukuita kwekuvhura nekuvhara, valve inogona kumiswa pane chero nzvimbo yepakati nebhatani rekumira. Stop action inonyanya kushandiswa kugadzirisa system.

Manual pombi inonyanya kushandiswa kugadzirisa system. Kana pasina magetsi kana pombi yemafuta haigone kushanda zvakajairika, kuzunungusa pombi yemanyorero kunogonawo kupedzisa kuvhurwa kwevhavha uye kudzvanywa kwekuchengetedza sisitimu. Vhura iyo inowanzovharwa yekumisa vharafu, pasi pekuita kwesando simba rinogoneka uye hydrodynamic torque, tsvimbo yekubatanidza inotyaira ndiro yeshavishavi kuti itenderere kuvhara vharuvhu.
