Mapombi eMvura yeMoto yeMashandisirwo Akasiyana

Nzira yekusarudza pakati pemapombi akatwasuka uye akatwasuka uye pombi yemvura yemoto masisitimu?

Pombi Yemvura YemotoPfungwa

Pombi ye centrifugal yakakodzera kushandiswa kwemvura yemoto inofanira kuva nemhepo yakatsetseka. Pombi yakadaro yakakura kune iyo yakanyanya kudiwa imwe chete yemoto wakakura muchirimwa. Izvi zvinowanzoshandura kumoto wakakura muchikamu chikuru chechirimwa. Izvi zvinotsanangurwa nechiyero chakayerwa uye yakatarwa musoro wepombi seti. Mukuwedzera, pombi yemvura yemoto inofanira kuratidza kukwanisa kwekuyerera kukuru kudarika 150% yehuwandu hwehuwandu hwayo hune huwandu hunopfuura 65% yemusoro wayo wakatemerwa (discharge pressure). Mukuita, pombi dzemvura dzemoto dzakasarudzwa dzinopfuura tsika dzambotaurwa. Pakave nemapombi akawanda akanyatsosarudzwa emvura yemoto ane ma curve akadzikama ayo anogona kupa zvinopfuura 180% (kana kunyange 200%) yehuwandu hwakatarwa pamusoro uye kupfuura 70% yemusoro wakatemerwa musoro.

Maviri kusvika mana matangi emvura yemoto anofanirwa kupihwa pane iyo yekutanga tsime remvura yemoto. Mutemo wakafanana unoshanda kumapombi. Mapombi maviri kana mana emvura yemoto anofanira kupihwa. Chimiro chakafanana ndeichi:

● pombi dzemvura dzemoto mbiri dzemagetsi (imwe inoshanda uye imwe yakamira)

● pombi mbiri dzedhiziri dzinotyairwa mvura yemoto (imwe inoshanda uye imwe yakamira)

Rimwe dambudziko nderekuti pombi dzemvura dzemoto dzinogona kusashanda kwenguva yakareba. Zvisinei, panguva yemoto, mumwe nomumwe anofanira kukurumidza kutangwa uye kupfuurira kushanda kusvikira moto wadzimwa. Naizvozvo, zvimwe zvigadziro zvinodiwa, uye pombi yega yega inofanirwa kuongororwa nguva nenguva kuti ive nechokwadi chekutanga nekukurumidza uye kushanda kwakavimbika.

Horizontal Pombi vs. Vertical Pumps

Horizontal centrifugal pombi imhando inofarirwa nevashandisi vepombi yemvura yemoto. Chimwe chikonzero cheizvi iko kuzunguzika kwakanyanyisa uye inogona kutambudzika mumichina yemapombi makuru akamira. Zvisinei, pombi dzakamira, kunyanya vertical-shaft turbine-type pombi, dzimwe nguva dzinoshandiswa sepombi dzemvura yemoto. Muzviitiko apo mvura yemvura iri pasi pe discharge flange centerline, uye kudzvinyirira kusina kukwana kuti mvura iende kune pombi yemvura yemoto, vertical-shaft turbine-type pombi inogona kushandiswa. Izvi zvinonyanya kushanda kana mvura yemumadziva, madziva, matsime, kana gungwa ichizoshandiswa semvura yemoto (seyosiyo huru kana seyokuchengetedza).

Pamapombi akamira, kunyura kwembiya dzepombi ndiko kurongeka kwakaringana kwekushanda kwakavimbika kwepombi yemvura yemoto. Rutivi rwekusveta rwepombi yakamira runofanira kuiswa mukati memvura, uye kunyura kwechipiri chemupombi kubva pasi pembishi yepombi kunofanirwa kunge kuri kupfuura mamita matatu kana pombi ichishandiswa pachiyero chayo chekuyerera. Zviripachena, uku ndiko kurongeka kwakaringana, uye ruzivo rwekupedzisira uye kunyudza kunofanirwa kutsanangurwa nyaya nemhosva, mushure mekutaurirana nemugadziri wepombi, zviremera zvemoto zvemuno nevamwe vanobatana.

Pakave nezviitiko zvakati wandei zvekudengenyeka kwepamusoro mumapombi makuru emvura yemoto. Naizvozvo, kuchenjerera kusimba zvidzidzo uye tsinhiro dzinodiwa. Izvi zvinofanirwa kuitwa kune ese maficha ekuchinja maitiro.
