Kufanana nemapombi mazhinji, iyo centrifugal pombi inoshandura meyiki simba kubva kumota kuenda kune simba remvura inofamba; mamwe emagetsi anopinda mukinetic energy yekufamba kwemvura, uye mamwe kuita simba rinobvira, rinomiririrwa nemhepo inomanikidza kana nekusimudza iyo mvura inopesana negiravhiti kusvika padanho repamusoro.
Kuti uwane rumwe ruzivo pamusoro penyaya iyi, ona Centrifugal compressor.
Kuendeswa kwesimba kubva kumakaniki kutenderera kwemhepo kuenda kune kumanikidza uye kumanikidza kwemvura kunowanzo rondedzerwa maererano nesimba remazana, kunyanya muzvinyorwa zvekare zvakanyorwa pamberi pesimba remazuva ano re simba re centrifugal sesimba rekunyepedzera mune yakatenderera furemu yakataurwa zvakanaka. Pfungwa yesimba re centrifugal hainyatso kudikanwa kutsanangura zvinoitwa nepombi ye centrifugal.
Mune pombi yazvino centrifugal pombi, yakawanda yeshanduko yesimba iri nekuda kwesimba rekunze iro rakakombama mashizha emhepo anopa pane inoyerera. Nguva dzese, rimwe simba rinosundirawo mvura yacho kuita kufamba kwedenderedzwa, uye kufamba uku kwakaita denderedzwa kunogona kuburitsa rimwe simba nekuwedzera kumanikidza panobuda. Hukama huripo pakati pemaitiro aya hwakatsanangurwa, pamwe neyakajairika pfungwa yemasimba ezana rinozivikanwa seiyo nguva iyoyo, muchinyorwa cha1859 pamapombi epentrifugal, nekudaro kusvika nenzira yakapfava pane iyo yakangopihwa pazano rakawanda remaitiro ekuita. yeiyo kunze whirlpool mukuvandudza mashandiro epombi centrifugal, zvinongofanirwa kufunga kuti huwandu hwemvura inotenderera mukamuri yemhepo, kutenderera denderedzwa revhiri, rinofanirwa kunge riine simba re centrifugal, uye kuti iri simba re centrifugal zvinofungidzirwa nyore kuti zviwedzere kune iyo yekunze simba rakagadzirwa mukati megumbo; kana, mune mamwe mazwi, kuenda kunowedzera simba rekupomha vhiri. Simba rekunze rinogadzirwa mukati megumbo rinofanirwa kunzwisiswa sekuburitswa chose nepakati pasimba re centrifugal kana mavanes eiri vhiri akatwasuka uye akatenderera; asi kana akakombama, sezvazvinowanzoitika, simba rekunze rinogadzirwa nepakati nepakati pesimba remazana, uye chikamu chichiiswa nevanes kumvura sechinhu chakakomberedza chekumanikidza, izvo, zvichitevera kuenzana kune nharaunda, anoshanda kumvura painofamba ichienda kunze pamwe chete navo. Panyaya iyi zvakanaka kucherechedza kuti nepo huwandu hwemvura yakaitwa kuti ipfuure nepombi yakapihwa ine mavanes akakombama ichinyatso shanduka pakunakidzwa, idiki huwandu hwacho hunowedzera kuita simba rinogadzirwa mukati megumbo rekukonzera mvura kunze rinova simba rezana, uye zvakanyanya pombi ichava izvo izvo zita raiwanzopihwa kwairi zvinoita senge inoratidza - pombi chaiyo yezana centrifugal. Kana, zvakadaro, iyo centrifugal pombi ine vanes yakakomberedzwa neshure mumafomu akadaro anowanzo shandiswa mumienzaniso yakanyatsogadzirwa yemuchina, inotyairwa nespeed zvakanyanya pamusoro peiyo inodiwa kungokunda kumanikidzwa kwemvura, uye kukonzera kusimudza kana kufambisa kutanga, iro radial chikamu chesimba rinoiswa kumvura nemavanes chichava chakakura, uye mvura ichisiya denderedzwa regumbo ichave nevelocity iri pasi peiyo yedenderedzwa regumbo mune degree rine kukosha chaiko mukati dzidzira.
Chirevo "kuwanda kwemvura ... kunofanirwa kunge kuchishandisa simba rezana" inoshandurika tichitarisa nezvesimba rezvekuita centrifugal-simba racho harisi simba rekunze riri pamusoro pemvura, asi asi simba rekunze rinoitwa nemvura, papombi pekugara. (volute) uye pamusoro pemvura iri pombi yekuburitsa. Kumanikidza kwekunze chiratidzo chekumanikidza kunoisa simba repakati rino tenderedza nzira yemvura kuti ifambe yakatenderera mukati mepombi (munzvimbo iripanze kunze kwemupeperesa, iyo yekunze whirlpool sekudanwa kunoitwa nemunyori uyu). Kune rimwe divi, chirevo chekuti "simba rekunze rakagadzirwa mukati megumbo rinofanirwa kunzwisiswa sekugadzirwa zvizere nesimba re centrifugal simba" inonyatsonzwisiswa maererano nezvesimba re centrifugal sesimba rekunyepedzera muchimiro chereferenzi kutenderera impeller; iwo chaiwo masimba ari pamusoro pemvura ari mukati, kana centripetal, nekuti ndiwo mafambiro emasimba anoda kuita kuti mvura ifambe mumatenderedzwa. Iri simba rinopihwa neyakaomeswa gradient iyo inomisikidzwa nekutenderera, uko kumanikidza kwekunze, kumadziro eiyo volute, kunogona kutorwa sesimba rezvekuita centrifugal. Izvi zvinowanzoitika pakunyora kwezana remakore rechi19 nekutanga, kusanganisa pfungwa idzi dzesimba ramazana muzvitsananguro zvisina kurongwa zvemhedzisiro senge iri mupombi yepentrifugal.
