Nzira yekuisa sei pombi yemvura inlet uye pombi dzekubuda?
Kana pombi yepombi yekubuditsa mvura yaiswa, pombi yedhayamita inoshanduka inofanirwa kunge iri concentric dhiyamita yepombi, uye hosi yerabha inochinjika inofanira kubatanidzwa pachiteshi chepombi kuderedza simba rekuzunguza rinoendeswa kupombi nekuda kwekuzunguzika kwepombi, uye geji yekumanikidza inofanirwa kuiswa papombi pfupi pamberi pevhavha, uye cheki vharafu uye gedhi vharafu (kana yekumisa vharafu) inofanira kuiswa pane inobuda pombi. Basa revhavha yecheki nderokudzivirira mvura yepombi yekubuda kuti irege kuyerera ichidzokera kune pombi uye ichikanganisa impeller mushure mekunge pombi yamira. Mvura inopinza pombi yekuisa chirongwa yakafanana ne: self-priming pombi yemvura yekuisa pombi yekuisa ndiyo inonyanya kukosha chikamu chinokanganisa kusveta kweyega-priming pombi, kuisirwa hakuna kunaka kuvuza, pombi yakarebesa, yakawandisa, idiki, iyo huwandu hwegokora uye dhigirii regokora huchakanganisa zvakananga iyo yega-priming pombi yekusveta mvura. 1, muromo mukuru wega-priming pombi ine pombi shoma yemvura inopa mvura vanhu vazhinji vanofunga kuti izvi zvinogona kuvandudza musoro chaiwo wepombi yekuzvimisira, iyo chaiyo musoro weiyo self-priming centrifugal pombi = yakazara musoro ~ kurasikirwa kwemusoro. Kana iyo pombi yemhando yakatemwa, iyo yakazara musoro ndeyechokwadi; Kurasikirwa kwemusoro kwakakosha kubva pakupokana kwepombi, iyo diki dhayamita yepombi, iyo yakakura kushorwa, saka iyo yakakura kurasikirwa kwemusoro, saka kuderedza dhayamita, iyo chaiyo musoro wepombi yecentrifugal haigone kuwedzera, asi ichaderera. zvichikonzera kudonha kwepombi yekuzvimisikidza. Saizvozvo, kana pombi yemvura diki dhayamita ichishandisa pombi hombe yemvura kupomba mvura, haingaderedze musoro chaiwo wepombi, asi inoderedza kurasikirwa kwemusoro nekuda kwekuderedzwa kwepipeline kuramba, kuitira kuti musoro chaiwo uvandudzwe. . Kune zvakare michina inofunga kuti kana diki dhayamita pombi yemvura pombi ine mapombi makuru emvura, ichawedzera zvakanyanya mutoro wemota. Vanofunga kuti dhayamita yepombi inowedzera, mvura iri mupombi yekubuda kwemvura ichaita dzvinyiriro huru pane pombi impeller, saka ichawedzera zvikuru mutoro wemotokari. Sezvo munhu wese anoziva, saizi yekumanikidza kwemvura inongoenderana nekukwirira kwemusoro, uye haina chekuita nehukuru hwepombi cross-sectional area. Chero bedzi musoro uine chokwadi, ukuru hwepunduki hwepombi inozvimisira haishanduki, zvisinei kuti dhayamita yepombi yakakura sei, kumanikidza kunobata pane inofefetera kune chokwadi. Zvisinei, pamwe nekuwedzera kwepipe dhayamita, kuyerera kunopesana kuchaderedzwa, uye chiyero chekuyerera chichawedzerwa, uye mari yemagetsi ichawedzerwa zvakakodzera. Asi chero bedzi muchikamu chemusoro wakarongwa, zvisinei kuti ungawedzera sei dhayamita yepombi inogona kushanda zvakanaka, uye inogonawo kuderedza kurasikirwa kwepombi, kuvandudza kushanda kwepombi. 2. Pakuisa pombi inopinza pombi yemvura, dhigirii kana kukwira kumusoro kuchaita kuti mweya uunganidzwe mupombi inopinza, vacuum yepombi yemvura uye pombi yecentrifugal, kuitira kuti musoro wekusveta wepombi yecentrifugal. inoderera uye kubuda kwemvura kunoderera. Yakarurama nzira ndeyokuti: dhigirii yechikamu inofanira kunge yakarerekera zvishoma kune kutungamira kwemvura sosi, haifanirwe kunge iri dhigirii, zvakanyanya kusarerekera kumusoro. 3. Kana mamwe magokora akashandiswa papombi inopinza yemvura yepombi yekuzvimisikidza, kudzivirira kwekuyerera kwemvura kunowedzerwa. Uye gokora rinofanira kutendeuka munzira yakatwasuka, usabvuma kutendeukira kudhigirii, kuti usatore mhepo. 4, iyo self-priming pombi inlet yakabatana zvakananga negokora, izvo zvichaita kuti mvura iyerere nepakati pegokora ichipinda mune impeller isina kuenzana kugovera. Kana iyo inlet pombi dhayamita yakakura kupfuura pombi yemvura inopinza, eccentric reducer pombi inofanira kuiswa. Iyo yakadzika chikamu che eccentric reducer inofanira kuiswa pamusoro, uye iyo yakarerekera chikamu inofanira kuiswa pazasi. Zvikasadaro, unganidza mweya, kuderedza huwandu hwemvura kana kupomba mvura, uye uve nekuputsika. Kana iyo dhayamita yepombi inopinza mvura yakafanana neyekupinza mvura kwepombi, pombi yakatwasuka inofanira kuwedzerwa pakati peinopinza mvura negokora. Kureba kwepombi yakatwasuka haifaniri kunge iri pasi pe2 kusvika ku3 paupamhi hwepombi yemvura. 5, iyo self-priming pombi yakashongedzerwa nevharuvhu yepasi pemvura inopinza pombi chikamu chinotevera hachisi chakamira, senge ichi kuisirwa, vharuvhu haigone kuvharwa yega, zvichikonzera kubuda kwemvura. Iyo chaiyo yekuisa nzira ndeye: yakashongedzerwa nevharuvhu yepasi pepombi yemvura inopinza, chikamu chinotevera chakanyanya vertical. Kana kuiswa kwakamira kusingagoneki nekuda kwemamiriro enzvimbo, Angle pakati pepiipi axis uye ndege yedhigirii inofanira kunge iri pamusoro pe60 °. 6. Nzvimbo yekupinda yepombi yepombi yepombi yemvura inopinza pombi haina kururama. (1) Chinhambwe chiri pakati pekupinzwa kwepombi yepombi yepombi yekupinza mvura uye pasi nemadziro epombi yemvura inopinza ishoma pane dhayamita rekupinda. Kana pasi pedziva paine madhaka uye imwe tsvina, nguva pakati peinopinza uye pasi pedziva ishoma kudarika 1.5 nguva yedhayamita, ichaita kuti kunwa kwemvura kusava kwakatsetseka kana uchipomba kana kusveta sediment nemarara, ichivharira chinopinda. (2) Kana kudzika kwemvura kwepombi yekupinza kwemvura kusina kukwana, zvinokonzeresa nzvimbo yemvura yakatenderedza pombi yekupinza mvura kuti ibudise mabhomba, zvichikanganisa kutorwa kwemvura uye kuderedza kubuda kwemvura. Iyo chaiyo yekuisa nzira ndeiyi: kudzika kwemvura kwepombi yemvura diki uye yepakati-kati haifaniri kunge iri pasi pe300 ~ 600mm, uye pombi huru yemvura haifanire kunge iri pasi pe600 ~ 1000mm7. Kubuda kwepombi yetsvina iri pamusoro pemvura yakajairika yedziva rekubuda. Kana iyo yekubuda yepombi yetsvina iri pamusoro peyakajairika mvura yemvura yedziva rekubuda, kunyangwe musoro wepombi uchiwedzerwa, kuyerera kunoderera. Kana iyo yekubuda kwemvura inofanira kunge yakakwira kupfuura yemvura yedziva rekubuda nekuda kwemamiriro enzvimbo, gokora uye pombi pfupi inofanira kuiswa mumuromo wepombi, kuitira kuti pombi ive siphon uye kureba kwekubuda kunogona kuderedzwa. 8. Self-priming sewage pump ine musoro wakakwirira unoshanda mumusoro wakaderera. Vatengi vazhinji vanowanzofunga kuti iyo yakaderera musoro we centrifugal pombi, iyo idiki iyo mota mutoro. Kutaura zvazviri, nokuda kwepombi yepombi, kana pombi yepombi yakagadziriswa, ukuru hwemashandisirwo emagetsi akaenzana nekuyerera kwepombi yepombi. Kuyerera kwepombi yetsvina kuchaderera nekuwedzera kwemusoro, saka kumusoro kwepamusoro, kuduku kunoyerera, kuduku kushandiswa kwesimba. Pane zvinopesana, iyo yakaderera musoro, iyo yakakura kuyerera, iyo yakakura kushandiswa kwesimba. Naizvozvo, kuitira kudzivirira kuwandisa kwemota, zvinowanzodiwa kuti iyo chaiyo yekupomba musoro wepombi haifanirwe kunge iri pasi pe60% yemusoro wakatemerwa. Saka kana musoro wepamusoro uchishandiswa pakupomba kwakadzikira kwemusoro, mota iri nyore kuwandisa uye kupisa, zvakakomba zvinogona kupisa mota. Muchiitiko chekushandiswa kwekukurumidzira, zvinodikanwa kuisa gedhi revhavha yekudzora mvura yekubuda mupombi yekubuda (kana kuvharira diki diki nehuni nezvimwe zvinhu) kudzikisa kuyerera uye kudzivirira mota kuwandisa. Ngwarira kukwira kwekushisa kwemota. Kana iyo mota ikawanikwa ichipisa, dzikisa kuyerera kwemvura kana kuivhara nenguva. Iyi pfungwa zvakare iri nyore kusanzwisisa, vamwe vashandisi vanofunga kuti kuvhara mvura yekubuda, kumanikidza kuderedzwa kwekuyerera, kuchawedzera mutoro wemotokari. Muchokwadi, pane zvinopesana, pombi yekubuda yenguva dzose yakakwirira-simba centrifugal pombi yemvura uye mayuniti ekudiridza ane gedhi mavharuvhu. Kuti uderedze mutoro wemotokari apo chikwata chinotanga, valve yegedhi inofanira kuvharwa kutanga, uye zvishoma nezvishoma yakavhurwa mushure mokunge motokari yatanga. Ichi ndicho chikonzero.
