Regulation of Split Casing Pumps
Kuchinja nguva dzose kwezvigadziro mumashandisirwo emabhizimisi kunoda kuti mapombi ashande mukati mehutano hwakasiyana-siyana hwekushanda. Izvo zvinoshanduka zvidimbu zvinosanganisira chiyero chinodiwa chekuyerera pamwe nechiyero chemvura, hurongwa hwekumanikidzwa, kuyerera kwekuyerera, nezvimwe. pombi yekasi yekuparadzanisa system inofanirwa kudzorwa. Izvi zvinogona kuitwa nemaoko kana otomatiki.
Muchidimbu, kushandiswa kwesimba mukushandiswa kwega kwega kunofanirawo kugadziriswa, nokuti kwete chete chimiro chechimiro chepombi uye hurongwa hunofanira kufungwa, asiwo nguva inoramba ichishanda yepombi imwe neimwe pasi pemamiriro akasiyana ekushanda. Iyo pombi inowanzogadziriswa maererano nekuchinja kwehuwandu hwemvura. Iyo chaiyo yakayerwa mwero wemvura kureba inoshandiswa sechiratidzo chekudzora kugadzirisa kumhanya, kudzora throttle chinzvimbo chevhavha, iyo inlet guide vane, uye kuvhura kana kuvhara mamwe mapombi muhurongwa. Details ndeiyi:
1. Throttle valve regulation nekugadzirisa valve pamutsara wekubuda, maitiro ehurongwa anoshandurwa kuti awane kuyerera kunodiwa.
2. Kuronga kwekukurumidza kunogona kusanganiswa nekugadzirisa kukurumidza kuderedza migumisiro yakaipa ye throttle valve regulation, kunyanya kuchengetedza kushandiswa kwesimba kusingakoshi.
3. Bypass regulation Kuti udzivise kumhanya pamutoro wakaderera, chikamu chidiki chekuyerera chinodzoserwa kubva papombi yekuburitsa kuenda kune yekusveta pombi kuburikidza nepombi yekupfuura.
4. Rongedza impeller blades ye pombi yekasi yekuparadzanisa. Pamapombi ekuyerera akavhenganiswa uye axial flow pumps ane chaiyo kumhanya kwe ng = 150 kana kupfuura, pombi inogona kuva nepamusoro-soro muhutano hwakasiyana nekugadzirisa mashizha.
5. Pre-swirl kugadziriswa Maererano neEuler equation, musoro wepombi unogona kuchinjwa nekushandura vortex pane impeller inlet. Pre-swirl inogona kuderedza musoro wepombi, nepo reverse pre-swirl inogona kuwedzera musoro wepombi.
6. Mutungamiri vane kugadzirisa kwe split casing mapombi ane epakati uye akaderera chaiwo kumhanya, iyo yepamusoro-soro poindi inogona kugadziridzwa mune yakasarudzika yakafararira nekugadzirisa ekutungamira vanes.
