Chikamu chechina Variable-diameter kushanda kwe vane pombi
Variable-diameter operation zvinoreva kucheka chikamu chepakutanga chinopenesa chevane pombi palathe pamwe nedhayamita rekunze.Mushure mokunge impeller yakatemwa, kushanda kwepombi kuchachinja maererano nemimwe mitemo, nokudaro kuchinja nzvimbo yekushanda yepombi.
Kucheka mutemo
Mukati mehumwe huwandu hwekucheka huwandu, kushanda kwepombi yemvura pamberi uye mushure mekucheka kunogona kutorwa sekusachinja.
Matambudziko anoda kutariswa mukucheka impeller
Pane imwe muganho kune yekucheka huwandu hweiyo impeller, zvikasadaro chimiro cheiyo impeller ichaparadzwa, uye iyo yekubuda kwemvura yekupedzisira yeblade ichawedzera kukora, uye kubvumidzwa pakati peimpeller uye pombi casing kuchawedzera, iyo ichawedzera. kukonzera kushanda kwepombi kudonha zvakanyanya.Iyo yakawanda yekucheka huwandu hwe impeller inoenderana nekumhanya chaiko.
Kucheka impeller yepombi yemvura inzira yekugadzirisa kupokana pakati pekuganhurirwa kwemhando yepombi uye kutsanangurwa uye kusiyanisa kwezvinhu zvinopa mvura, izvo zvinowedzera huwandu hwekushandisa pombi yemvura.Kushanda kwepombi kunowanzova chikamu che curve apo kushanda kwakanyanya kwepombi kunoderera nekusapfuura 5% ~ 8% .
Muenzaniso:
Muenzaniso: SLW50-200B
Impeller yekunze dhayamita: 165 mm, musoro: 36m.
Kana tikashandura dhayamita yekunze ye impeller ku: 155 mm
H155/H165= (155/165)2 = 0.852 = 0.88
H(155) = 36x 0.88m = 31.68m
Kupfupisa, kana iyo impeller dhayamita yemhando iyi yepombi yakatemwa kusvika 155mm, musoro unogona kusvika 31 m.
Notes:
Mukuita, kana nhamba yemashizha iduku, musoro wakashandurwa wakakura kudarika wakaverengwa.
