Kana ichangobva kushumirwa horizontal split case pombi ichiita zvisina kunaka, nzira yakanaka yekugadzirisa matambudziko inogona kubatsira kubvisa zvakawanda zvingangoitika, zvinosanganisira matambudziko nepombi, mvura inopomba (pombi yekupomba), kana mapaipi, mafittings, uye midziyo (system) yakabatana nepombi. Nyanzvi ine ruzivo ine nzwisiso yekutanga yepombi curves uye maparamita ekuita anogona kukurumidza kudzikamisa mikana, kunyanya iyo ine hukama nemapombi.

chinjikira Split Case Pamapu

Kuti uone kana dambudziko riri papombi, pima huwandu hwepombi ine simba remusoro (TDH), kuyerera, uye kushanda zvakanaka wozvienzanisa necurve yepombi. TDH ndiwo mutsauko uripo pakati pekubuda kwepombi nekudzvinyirirwa, kushandurwa kuita tsoka kana mamita emusoro (Cherechedza: Kana paine musoro mudiki kana pasina kana kuyerera pakutanga, vhara pombi nekukasira uye uone kuti pane mvura yakakwana mupombi, kureva, imba yepombi izere nemvura. Kuomesa pombi kunogona kukanganisa zvisimbiso. Kana nzvimbo yekushanda iri pamukombe wepombi, pombi iri kushanda nemazvo. Naizvozvo, dambudziko riri nehurongwa kana kupomba midhiya maitiro. Kana nzvimbo yekushanda iri pazasi pepombi curve, dambudziko rinogona kunge riri nepombi, sisitimu, kana kupomba (kusanganisira midhiya maitiro). Kune chero kuyerera chaiko, kune musoro unoenderana. Iyo dhizaini yeimpeller inosarudza kuyerera chaiko uko pombi inoshanda zvakanyanya - iyo yakanyanya kunaka poindi poindi (BEP). Matambudziko mazhinji epombi uye mamwe matambudziko ehurongwa anoita kuti pombi ishande panzvimbo iri pazasi pepombi yayo yakajairika. Nyanzvi inonzwisisa hukama uhwu inokwanisa kuyera mashandiro epombi oisa dambudziko kune pombi, kupomba, kana hurongwa.

Pumped Media Properties

Mamiriro ekunze akadai setembiricha anoshandura viscosity yepombi media, iyo inogona kushandura musoro wepombi, kuyerera, uye kushanda zvakanaka. Mineral mafuta muenzaniso wakanaka wemvura inoshandura viscosity nekushanduka kwekushisa. Kana iyo pumped media iine asidhi yakasimba kana base, dilution inoshandura iyo chaiyo giravhiti, iyo inokanganisa simba curve. Kuti uone kana dambudziko riri neiyo pumped media, zvimiro zvayo zvinoda kuongororwa. Kuedza iyo pumped media ye viscosity, chaiyo giravhiti, uye tembiricha zviri nyore uye zvisingadhure. Matafura ekushandura akajairwa uye mafomula anopihwa neHydraulic Society nemamwe masangano anogona kuzoshandiswa kuona kana iyo pumped media iri kukanganisa kuita kwepombi.

maitiro

Kamwe iyo midziyo yemvura yave yakatongerwa kunze senge pesvedzero, dambudziko riri nekutsemuka kwepakati pombi yemhosva kana hurongwa. Zvakare, kana pombi iri kushanda papombi curve, iri kushanda nemazvo. Muchiitiko ichi, dambudziko rinofanira kunge riri nehurongwa iyo pombi yakabatana nayo. Pane zvinhu zvitatu zvinogoneka:

1. Kana kuyerera kwakanyanyisa, saka musoro wakanyanyisa

2. Kana musoro wakanyanya kuderera, zvichiratidza kuti kuyerera kwakanyanyisa

Paunenge uchifunga nezve musoro uye kuyerera, yeuka kuti pombi iri kushanda nemazvo pane yayo curve. Naizvozvo, kana imwe yakadzikira, imwe yacho inofanira kunge yakanyanyisa.

3. Imwe mukana ndeyekuti pombi isiriyo iri kushandiswa mukushandisa. Kungave nekusaita dhizaini kana nekuisa zvisirizvo kwezvikamu, kusanganisira kugadzira/kuisa iyo isiriyo impeller.

Kuyerera kwakadzika kwazvo (Musoro Wakanyanya Kunyanya) - Kuyerera kwakaderera kunowanzoratidza kurambidzwa mumutsara. Kana iyo inorambidzwa (kupokana) iri mutsetse wekusveta, cavitation inogona kuitika. Zvikasadaro, kurambidzwa kunogona kunge kuri mumutsara wekuburitsa. Zvimwe zvingangoitika ndezvekuti kusveta static musoro wakanyanya kuderera kana discharge static musoro wakanyanya kukwirira. Semuenzaniso, tangi yekuyamwa / tangi inogona kunge iine switch yekuyangarara inotadza kuvhara pombi kana nhanho inodonha pazasi penzvimbo yakatarwa. Saizvozvo, iyo yakakwira nhanho switch pane yekuburitsa tangi / tangi inogona kunge isiriyo.

Musoro wakaderera (kuyerera kwakawandisa) - Musoro wepasi unoreva kuyerera kwakawandisa, uye kazhinji hausi kuenda kwaunofanirwa. Kudonha muhurongwa kunogona kuva mukati kana kunze. A diverter valve inobvumira kuyerera kwakawandisa kuti idarike, kana kuti yakundikana cheki vharuvhu inoita kuti kuyerera kutenderere kumashure kuburikidza nepombi yakafanana, inogona kukonzera kuyerera kwakanyanya uye musoro mudiki. Mumvura yakavigwa yemanisiparati, kudonha kukuru kana kuputika kwemutsara kunogona kukonzera kuyerera kwakanyanya, izvo zvinogona kukonzera yakaderera musoro (yakaderera mutsara kudzvanywa).

Chii chingave chakaipa?

Kana pombi yakavhurika ikatadza kumhanya pacurve, uye zvimwe zvikonzero zvakabviswa, zvinonyanya zvikonzero zvinokonzeresa:

- Yakakuvadzwa impeller

- Yakavharwa impeller 

- Yakavharwa volute

- Yakanyanyisa kupfeka mhete kana impeller clearance

Zvimwe zvinokonzeresa zvinogona kunge zvine chekuita nekumhanya kwepombi yakachinjika yekuparadzanisa - shaft inotenderera mune impeller kana isiriyo yekumhanyisa mutyairi. Nepo kumhanya kwemutyairi kunogona kusimbiswa kunze, kuongorora zvimwe zvikonzero zvinoda kuvhura pombi.
