1. Tsanangudzo yekumhanya chaiyo
Iyo chaiyo kumhanya kwepombi yemvura inopfupikiswa seyekumhanya chaiko, iyo inowanzomiririrwa nechiratidzo ns. Iyo chaiyo yekumhanyisa uye yekutenderera kumhanya ipfungwa mbiri dzakasiyana zvachose. Iyo chaiyo yekumhanyisa idata rakazara rakaverengerwa nekushandisa akakosha paramita Q, H, N, anoratidza maitiro epombi yemvura. Inogona zvakare kunzi comprehensive criterion. Iyo yakanyatsoenderana nechimiro chechimiro chepombi impeller uye kuita kwepombi.
Calculation formula yeChaiyo Kumhanya muChina
Calculation formula yeChaiyo Kumhanya kunze kwenyika
1. Q uye H inoreva kuyerera kwehuwandu uye musoro pahutano hwepamusoro, uye n inoreva kukurumidza kwekugadzira. Papombi imwe chete, kumhanya chaiko kune imwe kukosha.
2. Q uye H mune chirevo chinoreva chiyero chekuyerera kwekugadzira uye musoro wekugadzira we single-suction single-stage pump. Q/2 inotsiviwa pombi yekusveta kaviri; Pamapombi akawanda-matanho, musoro wekutanga-impeller unofanirwa kutsiviwa nekuverenga .
| Pump style | Pombi yeCentrifugal | Musanganiswa-kuyerera pombi | Axial kuyerera pombi | ||
| Kuderera chaiko kumhanya | Kumhanya kuri pakati nepakati | High chaiyo kumhanya | |||

1. Pombi ine sipidhi yakaderera zvinoreva musoro wepamusoro uye kuyerera kudiki, nepo pombi ine sipidhi yakakwirira inoreva kudzika musoro uye kuyerera kwakakura.
2. Ipeller ine yakaderera chaiyo sipidhi yakamanikana uye yakareba, uye iperesi ine yakakwirira chaiyo kumhanya yakafara uye ipfupi.
3. Iyo yakaderera chaiyo yekumhanya pombi inowanzoitika kune hump.
4, yakaderera chaiyo yekumhanya pombi, iyo shaft simba idiki kana kuyerera kuri zero, saka vhara vharuvhu kuti utange. Mapombi ekumhanya akakwira (mixed flow pump, axial flow pump) ane simba guru reshaft pazero kuyerera, saka vhura vharuvhu kuti itange.
