Penstock inoreva pombi inoendesa mvura kune hydraulic turbine kubva kudhiza kana hydropower station leveling chimiro (forebay kana surge chamber). Icho chikamu chakakosha chehydropower station, inoratidzwa nemateru, hombe yemvura yemukati, padyo neimba yemagetsi, uye inotakura hydrodynamic kudzvanywa kwesando yemvura. Nokudaro, inonziwo high pressure pipe kana high pressure water pipe.
Basa repombi yemvura inomanikidza kutakura simba remvura. Zvinogona kutaurwa kuti penstock yakaenzana ne "artery" ye hydropower station.
1, Chimiro chimiro chepenstock
Zvinoenderana neakasiyana zvimiro, zvishandiso, pombi marongero uye yakatenderedza midhiya, maitiro ezvimiro zvepenstocks akasiyana.
(1) Dhamu penstock
1. Pombi yakavigwa mudhamu
Mapeni akavigwa mukongiri yemutumbi wedhamu anonzi mapaipi akaiswa mudhamu. Mapombi esimbi anowanzoshandiswa. Mafomu ekugadzirisa anosanganisira inclined, horizontal uye vertical shafts
2. Penstock kuseri kwedhamu
Kuiswa kwepombi dzakavigwa mudhamu kune kukanganisa kukuru pakuvakwa kwedhamu, uye kunokanganisa kusimba kwedhamu. Naizvozvo, pombi yesimbi inokwanisa kurongwa pamateru edhamu rezasi mushure mekupfuura nepamusoro pedhamu repamusoro kuti ive pombi yekumashure yedhamu.
(2) Surface penstock
Iyo penstock ye diversion type ground powerhouse inowanzoiswa mumhepo yakashama padivi pemutsetse wegomo remateru kuti iite pasi penstock, iyo inonzi iyo yakavhurika pombi kana yakavhurika penstock.
Maererano nemhando dzakasiyana dzepombi, pane kazhinji marudzi maviri:
1. Simbi pombi
2. Yakasimbiswa kongiri pombi
(3) Underground penstock
Kana iyo topographical uye geological mamiriro asina kukodzera kuvhurika pombi marongero kana chiteshi chemagetsi chakarongedzwa pasi pevhu, iyo penstock inowanzorongedzerwa pazasi pevhu kuti ive yepasi pevhu. Kune marudzi maviri epasi pevhu penstocks: yakavigwa pombi uye backfilled pombi.
2, Mvura yekupa maitiro kubva penstock kusvika kune turbine
1. Mvura yakasiyana-siyana: imwe penstock inongopa mvura kune imwe chete, kureva, imwe pombi imwe chete yemvura.
2. Mvura yakasanganiswa yemvura: pombi huru inopa mvura kune zvikamu zvose zvechiteshi chemagetsi mushure mokunge magumo apera.
3. Mvura yakabatanidzwa
Imwe neimwe pombi huru ichapa mvura kune maviri kana anopfuura mayuniti mushure mekuita branching kumagumo, kureva, mapaipi akawanda uye akawanda mayuniti.
Kunyangwe mvura yakabatana kana yeboka yemvura yakagamuchirwa, nhamba yezvikamu zvakabatanidzwa kune imwe neimwe pombi yemvura haifaniri kudarika 4.
3, Mvura inlet mode ye penstock inopinda mu hydropower house
Iyo axis yepenstock uye hukama hwakananga hwechirimwa hunogona kurongwa mune yakanaka, lateral kana oblique kutungamira.
