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 inoshanda pamwe neinjini huru yepombi, zvinoenderana nemusimboti wehydraulic transition process, uye kuburikidza neyakagadzikwa yekuvhura nekuvhara maitiro, inogona kuona yakavimbika yekucheka-kubviswa kwepombi, kunyatsobvisa nyundo yemvura mukati. pombi, uye kuita basa mukuchengetedza kuchengetedzwa kwepombi system.

Kushanda musimboti

Iyo yakachengetwa yekuvhara simba reheavy sando hydraulic control inononoka kuvhara cheki butterfly vharafu inorema sando inogona simba, iyo yakakamurwa inorema sando otomatiki kumanikidza kuchengetedza hydraulic control inononoka kuvhara tarisa butterfly vharafu (inozonzi inorema sando kumanikidza kuchengetedza mhando) uye kukiya inorema sando otomatiki kumanikidza kuchengetedza hydraulic control inononoka kuvhara tarisa butterfly vharafu (inozonzi inorema sando yekukiya mhando). 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 yemafuta kuburikidza nevhavha yekudzora kuyerera uye hose yekudzvanya hose yekusundira piston uye kutyaira iyo lever yakabatana nayo kusimudza inorema sando kuenda. vhura vharuvhu. 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 vharafu, solenoid valve inodzokera kumashure, mafuta ekumanikidza ari mucylinder yemafuta anodzokera kutangi yemafuta kuburikidza nekukurumidza uye kunonoka kwejoint flow valve, high-pressure hose uye solenoid valve, sando inorema inowira pasi, uye tsvimbo yekubatanidza inotyaira. iyo butterfly plate kuti itenderere kuvhara valve, kuitira kuti ikurumidze kutema mvura yakawanda inoyerera inenge 70% yekurohwa kwekare; 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.
