Tinthu tachitsulo ndi madzi kutali ndi mayi

Slurry cavitation makina

Makamaka mawonekedwe a masamba ndi otaya mofulumira imene mwadzidzidzi kusintha otaya makhalidwe a madzi mu Slurry otaya impeller, kupanga tsamba thirakiti madzimadzi kuthamanga kugawa anapereka kusalinganizika.

The madzi gawo polowera otaya tsamba , tsamba si akuchita madzimadzi kale , pali otsika kuthamanga dera kwanuko . Pamene otsika kuthamanga m`dera la madzi otaya kuthamanga yafupika kwa ano zimalimbikitsa nthunzi kutentha madzi, madzi nthunzi nthunzi kupanga thovu pang`onopang`ono anayamba; kuwira ndi madzimadzi akuyenda mu njira yoyenda panthawiyo ndipo kumapangitsa kuti kuthamanga kwanthawi yayitali kugwe. Mphindi kuwira anaphulika , madzimadzi ozungulira kuwira anaphulika thovu anapanga pamene anakhamukira mofulumira mabowo , ndipo limodzi ndi localized kutentha , kuthamanga kwa madzi nyundo chodabwitsa, umene ndi limagwirira cavitation . Malinga ndi akatswiri akunja experimental kafukufuku lipoti cavitation madzi nyundo ndi mbali yaikulu ya tsankho kuthamanga kwa 30MPa (manometry dera la 1.5mm2). Kuyesedwa cavitation kumachitika pamene madzi madzi nyundo pafupipafupi 25,000 nthawi / sekondi , pamwamba zitsulo pansi nyundo madzi mobwerezabwereza anakantha ndi kuwonongeka kutopa.

Ndipo, mosalekeza cyclical kuthamanga yoweyula , madzi mwamsanga kulowa ndi kutuluka pores zitsulo, pamwamba chitsulo cha concavity, zitsulo particles ndi madzi kutali mayi, chifukwa pitting kwambiri. Magawo akuluakulu a mpope mu mphamvu yanthawi zonse, pampu imayambitsa phokoso ndi kugwedezeka, kotero kuti cavitation yapampu imapweteka kwambiri, makamaka m'magawo otsatirawa: Kuchita kwa pampu nosedive.

Panthawiyi HQ curve, NQ yokhotakhota yotsika mwadzidzidzi,wopanga mpope wa slurrympope kwambiri sachiza, mpope otaya kusokoneza , makamaka chifukwa mpope cavitation , impeller ndi kutengerapo mphamvu pakati pa madzi otaya kuwonongeka ndi kusokoneza , njira yamadzimadzi otsekedwa osati ndi kuwira, ndi otaya kutaya kumawonjezeka. Chithunzi 2: Pampu ya Slurry imapanga kugwedezeka ndi phokoso. Cavitation imachitika pamene kuthamanga kuli kwakukulu pamodzi ndi kugwa kwa thovu nthawi zonse kumapangidwa ndi kugwedezeka kwamphamvu kwa hydraulic, kupangitsa kuti pampu igwedezeke ndi phokoso.

Slurry mpope makina padziko otaya zigawo zikuluzikulu kuchokera mawotchi kuwonongeka, pamwamba pa zisa impeller uchi kapena siponji. Ngati mpweya kumasulidwa pa vaporization wa madzi ndi dzimbiri, adzatulutsa zina mankhwala chiwonongeko ( chiwonongeko choyambirira ndi chachikulu).
