About Fluids uye Liquids muMultistage Vertical Turbine Pump
Kana iwe uchida kuziva zvese nezve multistage vertical turbine pombi , zvakakoshawo kuziva nezvemvura uye zvinwiwa zvazvinotakura.
Zvinwiwa uye Zvinwiwa
Pane musiyano unokosha pakati pezvinwiwa nezvinwiwa. Zvinwiwa (Liquids) zvinoreva chinhu chipi nechipi chiri pakati pezvikamu zvakasimba negasi. Kuti chinhu chiri muchimiro chemvura zvinoenderana netembiricha uye kumanikidzwa kwachinoitwa, pamwe nemukati mechinhu chechinhu chacho.
Mvura (fluid) chinhu chipi nechipi chinokwanisa kuyerera chichienderera uye chinokwanisa kuumba chero chimiro chemudziyo unacho. Kunyange izvi zvichinyatso tsanangura zvinwiwa, zvinogona zvakare kushandiswa kutsanangura magasi. Mune mamwe mazwi, zvinwiwa zvese zvinwiwa, asi hazvisi zvese zvinwiwa zviri mumamiriro emvura. Naizvozvo, kazhinji kutaura, kana izwi rekuti "fluid" rinoshandiswa mu multistage vertical turbine pombi, rinoreva zvinwiwa, sezvo pombi dzisina kugadzirwa kutakura magasi.
Zvinwiwa zvine zvinhu zvikuru zvemuviri zvinoda kutariswa mukupomba maapplication, zvinoti viscosity, density, uye vapor pressure (vaporization pressure). Izvi zvimiro zvakakosha kuti unzwisise maitiro emvura uye kuti ndeipi pombi inonyatso kufanira kwairi.
Viscosity zvinoreva kuramba kwemvura kuyerera, kana kuti "kunamira" kwemvura. Izvi zvinokanganisa chiyero chekuyerera, musoro wakazara, kushanda nesimba, uye simba rematanho akawanda akamira turbine pombi.
Density zvinoreva kuwanda kwechinhu chiri muhutatu hwakati. Pakupomba, inowanzodanwawo serevoor density (specific gravity), inova reshiyo yedensity yechinhu kune density yemvura pane imwe tembiricha. Density uye giravhiti chaiyo inodiwa kuti uone simba rinodiwa kufambisa mvura inoenderana neimwe.
Vapor pressure ndiyo dzvinyiriro apo mvura inotanga kubuda (vaporize), uye zvakakosha kuti utarise izvi mupombi system. Kana kudzvanywa kwepombi kwakadzikira pane vaporization pressure yemvura, cavitation inogona kuitika.
Kunzwisisa mutsauko uripo pakati pezvinwiwa nezvinwiwa uye mabatiro anoita zvinwiwa kwakakosha pakushanda kwepombi yepombi yakatwasuka yakawanda.
