Basa repombi yemvura

Pombi dzemvura dzakagadzirwa pamwe nekuvandudzwa kwemaindasitiri. Muzana remakore rechi19, pakanga patova nemhando dzakakwana uye marudzi emapombi kunze kwenyika, ayo aishandiswa zvakanyanya. Sekureva kwehuwandu, kunosvika 1880, kugadzirwa kweakawanda-chinangwa centrifugal pombi akaverengera anopfuura makumi mapfumbamwe muzana eiyo yakazara pombi kugadzirwa, nepo yakakosha mapombi akadai semagetsi ekudyara pombi, pombi dzemakemikari, uye pombi dzemigodhi dzaingosvika gumi muzana. iyo yakazara pombi kugadzirwa. Pakazosvika 1960, pombi-chinangwa-chikuru chaiverengera chete 45%, nepo yakakosha-chinangwa pombi yaisvika 55%. Zvinoenderana nezviri kuitika pari zvino, chikamu chepombi dzechinangwa chakakosha chinenge chakakwira kupfuura chepombi dzechinangwa.

Kare sekutanga kwezana ramakore rechi20, pombi dzepasi pemvura dzakatanga kugadzirwa neUnited States kutsiva mapombi akadzika etsime. Zvadaro, nyika dzeWestern Europe dzakaitawo tsvagiridzo nekusimudzira, dzichiramba dzichivandudza uye zvishoma nezvishoma dzichivandudza. Semuenzaniso, mugodhi wemarasha weRhine kuGermany unoshandisa pombi dzemagetsi dzinodarika mazana maviri nemazana mashanu, nehukuru hukuru hunosvika 1600kw uye musoro we410m.

Iyo submersible yemagetsi pombi munyika yedu yakagadziridzwa muma1960s, pakati peiyo submersible pombi yemagetsi panzvimbo yekushanda yakagara ichishandiswa kudiridza mumapurazi kumaodzanyemba, uye madiki uye epakati-saizi submersible pombi yemagetsi yakagadzira nhevedzano uye yakave. kuiswa mukugadzirwa kwehuwandu. Mapombi makuru uye mapombi emagetsi akakwira nemagetsi emagetsi akaunzwawo, uye pombi huru dzinopinda mumvura dzine simba re500 ne1200 kW dzakaiswa mukushanda mumigodhi. Semuyenzaniso, Anshan Iron and Steel Company inoshandisa 500kw submersible electric pombi kubvisa mugodhi wesimbi wakavhurika weQianshan, uyo une simba guru munguva yekunaya kwemvura. Pane zviratidzo zvekuti kushandiswa kwemapombi emagetsi asinganyuri mumvura kuchashandura midziyo yemumigodhi, nekukwanisa kutsiva pombi dzechinyakare dzakakura dzakachinjika. Pamusoro pezvo, mapombi emagetsi akakura emagetsi ari pasi pekuedzwa kugadzirwa.

Michina inoshandiswa kupomba, kutakura, uye kuwedzera dzvinyiriro yezvinwiwa inowanzonzi pombi. Kubva pakuona kwesimba, pombi muchina unoshandura simba remuchina weiyo prime mover kuita simba remvura inofambiswa, ichiwedzera kuyerera uye kudzvanywa kwemvura.

Basa repombi yemvura rinowanzo kukweva mvura kubva munzvimbo yepasi uye kuitakura ichitevedza pombi kuenda kunzvimbo yakakwirira. Somuenzaniso, chatinoona muupenyu hwedu hwemazuva ose kushandisa pombi kudhonza mvura kubva munzizi nemadziva kuti tidiridze minda; Semuenzaniso, kudhonza mvura kubva mumatsime akadzika ari pasi pevhu uye kuendesa kune shongwe dzemvura. Nekuda kwekuti dzvinyiriro yemvura inogona kuwedzera mushure mekupfuura nepapombi, basa repombi rinogona kushandiswawo kuburitsa mvura kubva mumidziyo ine kuderera kwakadzika uye kukunda kushorwa munzira yekuitakura kuenda nayo kumidziyo ine yakakwirira. kumanikidza kana dzimwe nzvimbo dzinodiwa. Semuenzaniso, iyo boiler feedwater pombi inokwevera mvura kubva kune yakaderera-kudzvanywa tangi yemvura yekudyisa mvura mudhiramu dhiramu nekumanikidza kwakanyanya.

Kushanda kwepombi kwakakura kwazvo, uye kuyerera kwemapombi makuru kunogona kusvika mazana ezviuru mazana m3 / h kana kupfuura; Kuyerera kwema micro pumps kuri pasi pemakumi emaml/h. Kudzvinyirira kwayo kunogona kusvika pamusoro pe1000mpa kubva kumhepo yemhepo. Inogona kutakura zvinwiwa patembiricha kubva -200℃kusvika ku800℃. Kune akawanda marudzi ezvinwiwa zvinogona kutakurwa nemapombi,

Inogona kutakura mvura (mvura yakachena, tsvina, nezvimwewo), mafuta, acid-base zvinwiwa, emulsions, kumiswa, uye simbi dzemvura. Nekuda kwekuti pombi zhinji dzinoonekwa nevanhu muhupenyu hwavo hwemazuva ese dzinoshandiswa kutakura mvura, dzinowanzonzi pombi dzemvura. Zvisinei, sezwi guru repombi, izwi iri harina kuzara.
