Ungasarudza sei pakati pepombi dzakatwasuka nedzakatwasuka uye masisitimu emvura yepombi yemoto?
Pombi yeMvura yeMotoZvaunofanira Kufunga Nezve
Pombi ye centrifugal yakakodzera kushandiswa kwemvura yemoto inofanira kunge iine curve inoshanda yakati sandara. Pombi yakadaro yakakura zvichienderana nekudiwa kukuru kwemoto mukuru mufekitori. Izvi zvinowanzo reva moto mukuru mufekitori yakakura. Izvi zvinotsanangurwa nehukuru hwakatarwa uye musoro wepombi wakatarwa. Pamusoro pezvo, pombi yemvura yemoto inofanira kuratidza kugona kwekuyerera kwemvura kwakakura kupfuura 150% yehukuru hwayo hwakatarwa neinopfuura 65% yemusoro wayo wakatarwa (kumanikidzwa kwekubuda). Mukuita, pombi dzemvura yemoto dzakasarudzwa dzinopfuura kukosha kwataurwa pamusoro apa. Kwave kune pombi dzemvura yemoto dzakawanda dzakasarudzwa nemazvo dzine curve dzakati sandara dzinogona kupa anopfuura 180% (kana kunyange 200%) yehukuru hwakatarwa pamusoro uye anopfuura 70% yemusoro wese wakatarwa.
Matangi maviri kusvika mana emvura yemoto anofanira kupihwa uko kunobva mvura yemoto. Mutemo wakafanana unoshandawo pamapombi. Mapombi maviri kusvika mana emvura yemoto anofanira kupihwa. Hurongwa hwakajairika ndehwekuti:
● pombi mbiri dzemvura dzinofambiswa nemagetsi dzinofambiswa nemota (imwe inoshanda uye imwe yakamira)
● pombi mbiri dzemvura dzinofambiswa neinjini yedhiziri (imwe inoshanda uye imwe yakamira)
Dambudziko rimwe nderekuti pombi dzemvura dzinodzima moto dzinogona kusashanda kwenguva yakareba. Zvisinei, panguva yemoto, imwe neimwe inofanira kutanga kushanda ipapo ipapo kusvika moto wadzimwa. Saka, pane zvimwe zvinodiwa, uye pombi yega yega inofanira kuongororwa nguva nenguva kuti ive nechokwadi chekuti inotanga nekukurumidza uye inoshanda zvakavimbika.
Mapombi Akatambanudzwa vs. Mapombi Akamira
Pombi dze centrifugal dzakatwasuka imhando yepombi yemvura yemoto inodiwa nevakawanda. Chimwe chikonzero cheizvi kuzununguka kwakanyanya uye chimiro chemakanika chinogona kunge chisina kusimba chemapombi makuru akatwasuka. Zvisinei, pombi dzakatwasuka, kunyanya pombi dzemhando ye turbine dzakatwasuka, dzimwe nguva dzinoshandiswa sepombi dzemvura yemoto. Muzviitiko apo mvura iri pasi pepakati pe flange yekuburitsa mvura, uye kumanikidzwa kusina kukwana kuti mvura isvike kupombi yemvura yemoto, seti yepombi yemhando ye turbine yakatwasuka inogona kushandiswa. Izvi zvinonyanya kushanda kana mvura inobva mumadziva, madziva, matsime, kana gungwa ichishandiswa semvura yemoto (senzvimbo huru kana senzira yekuchengetedza).
Kune mapombi akamira, kunyudzwa kwendiro dzepombi ndiyo nzira yakanakisisa yekushanda zvakanaka kwepombi yemvura yemoto. Rutivi rwekukweva pombi yakamira runofanira kuiswa mukati memvura, uye kunyudzwa kweimpeller yechipiri kubva pasi pendiro yepombi kunofanira kunge kwakapfuura mamita matatu kana pombi ichishanda pamwero wayo wepamusoro wekuyerera. Zviri pachena kuti iyi igadziriro yakakodzera, uye ruzivo rwekupedzisira nekunyudzwa kunofanira kutsanangurwa nyaya imwe neimwe, mushure mekutaurirana nemugadziri wepombi, vakuru vemoto vemunharaunda nevamwe vane chekuita nazvo.
Kwave nezviitiko zvakawanda zvekudengenyeka kwakanyanya mumapombi makuru emvura yemoto akamira. Saka, zvidzidzo zvekuchenjerera uye kusimbiswa kwakanyatsojeka zvinodiwa. Izvi zvinofanirwa kuitwa pazvinhu zvese zvine chekuita nemaitiro anochinja.
