Maswera sei pakati pemapombi akatwasuka uye matipi emoto uye pombi yemoto yemvura masisitimu?
Pombi yemvura yemvuraKufunga
Pombi yeCentrifugal yakakodzera kuti zvikumbiro zvemvura zvinofanirwa kunge zvine gorofa rakapetwa. Pombi yakadaro yakagadzirirwa kukurumbira kamwechete kwemoto wakakura muchirimwa. Izvi zvinowanzoshandura kune yakakura-chiyero moto muchikamu chikuru chechirimwa. Izvi zvinotsanangurwa nekukasira simba uye kwakarambidzwa musoro wepombi yakatarwa. Uye zvakare, pombi yemoto yemoto inofanira kuratidza kugona kweyekuyerera chiyero chakakura kupfuura 150% yeiyo yayo yakavezwa yakawanda neinopfuura 65 yemusoro wayo wakatemerwa musoro (discharge kumanikidzwa kwayo). Mukudzidzira, madhiri akasarudzwa emoto anokonzeresa zvambotaurwa tsika. Pave paine akawanda akasarudzwa emoto emoto ane mapepa akapfava anokwanisa kupa zvinopfuura 180% (kana kunyange 200%) yeiyo yakaiswa simba mumusoro uye anopfuura 70% yemusoro wakarukwa.
Makumi maviri ematangi emvura emvura anofanirwa kupihwa uko iyo yekutanga yekupa mvura yemvura inowanikwa. Mutemo wakafanana unoshanda pamapombi. Maviri kusvika mana emoto emvura pumps inofanira kupihwa. Urongwa hwakajairika ndewekuti:
● Mota mbiri yemagetsi inotungamirwa nemoto yemvura (imwe inoshanda uye imwe kumira)
● Chechipiri injini inotungamirwa nemoto yemvura emvura (imwe inoshanda uye imwe mira)
Imwe dambudziko ndeyekuti moto wemoto wemoto ungashanda kwenguva yakareba. Nekudaro, panguva yemoto, mumwe nemumwe anofanira kutanga pakarepo uye arambe achishanda kusvikira moto wadzimwa. Naizvozvo, zvimwe zvinopihwa zvinodikanwa, uye pombi imwe neimwe inofanira kuyedzwa nguva nenguva kuti uve nechokwadi chekutanga uye kuvimbika kushanda.
Yakatwasuka pumps vs. Vertical pumps
Yakatwasuka centrifugal pumps vazhinji vashandisi vevashandi vepombi yemoto yemoto. Chimwe chikonzero cheizvi ndicho chakanyanya kujairika uye chinogona kunge chiri chekunyepedzera manhamba emakwenzi makuru emukati. Nekudaro, vertical pumps, kunyanya vertical-shaft turbine-mhando pumps, dzimwe nguva inoshandiswa semaputi emvura. Muzviitiko zvinowanikwa nemvura iri pasi peiyo discharge Flange Centerline, uye dzvinyiriro haina kukwana kuti mvura iwane pombi yemoto, iyo shaft turbine-mhando pombi yakashandiswa. Izvi zvinoshanda zvakananga kana mvura kubva kumakungwa, madziva, matsime, kana gungwa raizoshandiswa semvura yemoto (seyakanyanya sosi kana backup).
Kune vertical pumps, iyo submergence yemapombi ndiro ndiyo yakakodzera kugadzirisa kwekuvimbika kushanda kweiyo moto wemoto pombi yemoto. Rutivi rwakatwasuka rwembambo rwakatungamirwa runofanira kuiswa pakadzika mumvura, uye submergence yechipiri impeller kubva pasi pepombi inodarika 3 metrums ichishandiswa pachiyero chayo chinokurumidza kuyerera. Zviripachena, ichi chiitiko chakarongeka, uye kudzora kwekupedzisira uye submergence kunofanirwa kutsanangurwa kesi nekuda kwenyaya, mushure mekutaurirana nePombi Vagadziri, vatungamiriri vemoto yemunharaunda nevamwe vanobata.
Pave paine zviitiko zvakati wandei zvevakanyanya vibraties mune yakakura metical fire yemoto mapapu. Naizvozvo, nyatso dzidza zvidzidzo uye zvidzidzo zvinodiwa. Izvi zvinofanirwa kuitirwa zvese zvikamu zvehunyanzvi hunhu.
