Indasitiri yezvekudya ndiyo inonyanya kukosha indasitiri yekurarama kwevanhu, uye inoramba ichi "shanduka" nekuwedzera kwezvido zvevanhu. Kusarudzwa kwezvokudya nevanhu ndiko kudiwa kwakakosha kwezvokudya. Nekudaro, kazhinji midziyo yechikafu pachayo haigone kusangana nezvinodiwa zvemazuva ano kugadzirisa, izvo zvinoda kugadziridzwa uye kugadzirisa. Pasina kuchinja hunhu hwayo, tekinoroji yekugadzira tekinoroji yakaita basa rakakosha muindasitiri yechikafu.
Cavitation tekinoroji chikafu chekugadzira tekinoroji, iyo inoshandisa iyo ine simba simba rekuita rinogadzirwa nekudonha kwecavitation mabhubhu kusimudzira jet erosion effect. Munguva yecavitation process, iyo nguva iyo iyo cavitation bubble inodonha inoburitsa yemuno yakanyanyisa kupisa nekumanikidza kwakanyanya, kuperekedzwa nemafungu akasimba ekuvhundutsa, ma microjets, mhirizhonga, uye yakakwirira shear masimba, ayo anozoshandura chimiro chechinhu uye kushandura chimiro chechigadzirwa. Maitiro ekugadzirisa, akadai solubility, emulsification, rheology, etc. Mukuwedzera kune cavitation mechanism, cavitation teknolojia inewo thermal mechanism uye mechanical mechanism. Parizvino, kune maviri makuru marudzi ezvakajairika maapplication, imwe ndeye ultrasonic tekinoroji uye imwe yacho hydraulic cavitation tekinoroji.
Ultrasonic cavitation tekinoroji
Ultrasound is acoustic wave ine frequency yakakura kupfuura 20kHZ, iyo inoumba iyo mechanical vibration ye media particles mukati, zvichikonzera kupindirana kweacoustic wave nepakati. Kana iyo yemvura molecular chinhambwe ichipfuura yakakosha molecular chinhambwe chemvura, maburi anoumbwa, uye maburi achange ari muContinuous oscillation pasi pekuita kwemafungu eruzha) kana kudonha. Kana iyo yenguva pfupi cavitation bubble inodzikira kudonha, iyo yakanyanya diki nzvimbo yakatenderedza cavitation bubble inogona kuburitsa yakanyanya tembiricha uye yakanyanya kudzvanywa, ichiperekedzwa nemafungu akasimba ekuvhundutsa, nekudaro ichigadzira yakakosha yemuviri nemakemikari mhedzisiro.
Hydraulic cavitation tekinoroji
Hydraulic cavitation inoreva kuti kana mvura inopfuura nepakati pechinhu chinonzi throttle (senge orifice plate, venturi, nezvimwewo), nekuda kwekuvharidzirwa kwechinhu kumvura, mvura inoyerera inova yakakura uye kudzvinyirira kunoderera. Kana iyo dzvinyiriro yemvura ikaderedzwa kuita saturated vapor pressure kana kutonyanya kudzvanywa, nekuda kwekuvapo kwetudiki tusinganyunguke gasi cores mukati memvura, mvura inoputika uye inoburitsa huwandu hukuru hwecavitation bubble. Nekukurumidza kupora kwekumanikidza kwakatenderedza mvura, iyo cavitation bubbles inoputika pakarepo Kudzima, kuitira kuti hunhu hwezvinhu zvine hukama hushanduke. Kuburikidza neakawanda cavitation bubble chizvarwa uye mashandiro ekuparadza, izvo zvinhu zvinogona kuita zvaunoda. Kuita kwe hydraulic cavitation tekinoroji yakafanana neye ultrasonic wave. Simba rayo rakaderera pane iro re ultrasonic wave, asi cavitation rate uye simba rekuita rakakwirira kupfuura iro re ultrasonic wave.
Mhedzisiro ye ultrasonic cavitation uye hydraulic cavitation yakafanana, asi pane misiyano yemamiriro ekushandisa. Panyaya yekushandiswa, ultrasonic cavitation ine yakafara application range, nepo hydraulic cavitation inongoshanda kune "mvura" zvinhu. Iyo cavitation tekinoroji yakagadzira nekukurumidza mumakore achangopfuura. Mazhinji nzira dzinoverengeka dzakaita sechiedza cavitation uye particle cavitation iri kushandurwa kuita chigadzirwa chaicho. Inotarisirwa kuve imwe yedzakakosha nzira dzekugadzirisa muindasitiri yechikafu mune ramangwana.
