Mapaipi eSimbi Akagadzirwa neRabha
Mapaipi esimbi ane rabha akagadzirwa kuti ashandiswe mumhando dzakasiyana-siyana dzekupomba. Mashandisirwo akadai sekuburitsa mvura mumigodhi, mapombi ane simba guru, mitsetse mirefu yekumashure, mashandisirwo epombi dzine slurry uye mapombi egiravhiti. Mugumo wega wega une flange yakagadziriswa nerubha rakanyungudutswa.
Pombi yesimbi inogadzirwa nerabha isingaparare uye isingaparare inogadzirwa nepaipi yesimbi yakajairika sefuremu uye inoshandiswa nerabha isingaparare, isingaparare uye isingapisi selayer. Inosanganiswa netekinoroji yakakosha ine namatidziro inoshanda zvakanyanya. Inonyanya kushandiswa mukugadzira simbi, magetsi, indasitiri yemakemikari, peturu, marasha, simende nedzimwe nzvimbo dzemaindasitiri. Mubasa rekuchera, inoshandiswa zvakanyanya musystem yekutumira matope emugodhi, backfilling yemugodhi wemarasha uye minda yesystem yemapaipi ane hukama. Kunyanya, pombi yakakodzera kwazvo kutakura tembiricha iri pakati pe -50°C kusvika +150°C, iyo iri nyore kupfeka uye ngura. Tinogona kuwedzera ukobvu hwemadziro pakona yepombi zvichienderana nezvinodiwa nemutengi, nokudaro tichiwedzera hupenyu hwebasa. Panguva imwecheteyo, hupenyu hwebasa hwepombi yesimbi inogadzirwa nerabha hunogona kusvika makore 15-40 zvakazara. Pombi inogona kutenderedzwa nemadhigirii angangoita 90 mushure memakore 6-8 ebasa. Nguva imwe neimwe yekutenderera inogona kuwedzera hupenyu hwekushumira, pombi yesimbi inogona kudzokororwa nerabha katatu kusvika kana, nokudaro zvichideredza kushandiswa kwemari mune zvimwe zvinhu.
Zvikamu zvezvinodiwa zvepombi ine rabha

Zvinhu zvirimo
1. Kuvaka Kwakanaka Kwazvo
2. Kuramba kwakanaka kwekupfeka uye hupenyu hurefu hwebasa
3. Simba guru uye kuramba kwakasimba
4. Kudzivirira ngura zvakanaka
5. Kupisa kwakakura
6. Kubatanidza nekukurumidza uye kuiswa kuri nyore
