Iimpompo ze-SZB ze-vacuum ziyi-cantilever kunye ne-ringi yamanzi yodidi lwe-vacuum empompelwe ukumpompa umoya okanye enye igesi engancibilikiyo kunye namanzi engenamasuntswana aqinileyo.Ubuncinci boxinzelelo lokufunxa yi -0.086MPa.Zisetyenziswa ngokubanzi kumashishini oomatshini, i-petroleun, iikhemikhali, amayeza, ukutya njalo njalo, kwaye zifaneleke ngakumbi ukuphambukiswa kwamanzi amakhulu.
1. Umthamo wokufunxa kunye nokukhupha iqondo le-vacuum ukusuka kwi-40% ukuya kwi-90% okanye uxinzelelo olusuka kwi-0.05MPa ukuya kwi-0.15MPa luyahluka kunye nomthamo wonikezelo lwamanzi, isithuba phakathi kwe-impeller kunye ne-side cover, kunye nesithuba phakathi kwe-impeller. kunye nesigqubuthelo esisecaleni.Ngokukodwa xa isantya sokuhamba sincinci, ukuba ukulungiswa akuchanekanga, kunokwenzeka ukuba kubangele ukuhamba okuncinci.
2. Amaxabiso kwitheyibhile afunyanwa phantsi kwezi meko zilandelayo: ①Ubushushu bamanzi 15℃;②Umoya 20℃;③ Ubushushu obunxulumene nerhasi ngama-70%;④Uxinzelelo lwe-atmospheric 0.1013MPa
3. Ukutenxa kwentsebenzo kwitheyibhile akudluli kwi-5%).
