Ngokombono wezimiso zobuningi,imishini yokupakisha powderikakhulukazi babe nezindlela ezimbili: i-volumetric kanye nesisindo.

(1) Gcwalisa ngevolumu

Ukugcwaliswa kwe-quantitative okusekelwe kuvolumu kufinyelelwa ngokulawula umthamo wezinto ezigcwele. Umshini wokugcwalisa ubungako osuselwe kwisikulufa ungowesigaba sokugcwalisa umthamo osuselwe kuvolumu. Izinzuzo zayo ziyisakhiwo esilula, asikho isidingo semishini yokukala, izindleko eziphansi, nokusebenza kahle kokugcwalisa. Ububi bobuningi bohlobo lwesikulufuumshini wokugcwalisa i-powderukuthi ukunemba kokugcwalisa kuyahlukahluka kakhulu kuye ngokuthi izinto ezahlukene ezigcwaliswayo, ikakhulukazi zithembele ekuzinzeni kobuningi obubonakalayo bezinto ezigcwalisiwe, ukufana kobukhulu bezinhlayiyana zezinto ezibonakalayo, kanye nokumuncwa komswakama kanye nokuxega kwezinto. Ngakho-ke, ukugcwaliswa kwe-volumetric kulungele ikakhulukazi izinhlayiya zezinto ezibonakalayo ezinosayizi wezinhlayiyana ezifanayo, ukuminyana kwenqwaba okuzinzile, kanye nezakhiwo ezinhle zokuzigeleza.

Ukupakishwa kokugcwalisa kwevolumu okususelwa kumthamo kungahlukaniswa kube amafomu amabili ngokuya ngezindlela ezihlukene zokulinganisa zezinto:

1. Lawula izinga lokugeleza noma isikhathi sezinto ezigcwalisiwe ukuze ulawule ivolumu yokugcwalisa, isibonelo, ngokulawula inombolo noma isikhathi sokuzungezisa isikulufu emshinini wokugcwalisa isikulufa ukuze ulawule ivolumu yezinto ezigcwalisiwe, kanye nokulawula isikhathi sokudlidliza. yesiphakeli esidlidlizayo ukuze ulawule umthamo wento.
2. Ukusebenzisa isitsha sokulinganisa esifanayo ukulinganisa izinto zokugcwalisa ubuningi, njengokusebenzisa isilinda sokulinganisa, inkomishi yokulinganisa, noma umshini wokugcwalisa omningi wohlobo lwe-plunger.

Kungakhathaliseki ukuthi iyiphi indlela yokugcwalisa i-volumetric quantitative esetshenziswayo, kunenkinga evamile, okuwukuqinisekisa ukuzinza kobuningi bezinto ezigcwalisiwe ngangokunokwenzeka. Ukufeza le mfuneko, izindlela ezinjengokudlidliza, ukunyakazisa, ukugcwaliswa kwe-nitrogen, noma ukumpompa nge-vacuum zivame ukusetshenziswa. Uma kudingeka ukunemba kokugcwalisa okuphezulu, kuyadingeka ukusebenzisa idivayisi yokutholwa ngokuzenzekelayo ukuze uqhubeke nokubona izinguquko kubuningi obubonakalayo bezinto ezigcwele, bese ulungisa ngokuqhubekayo ukuze uqinisekise ukunemba kwevolumu yokugcwalisa.

(2) Gcwalisa ngesisindo

Uhlelo lokugcwalisa ukulinganisa ngokuyinhloko luqukethe injini yokushayela, idivayisi yokugcina, isikulufu, umkhono wokufaka isikulufa, njalonjalo. Ukuphakelwa kokuzungezisa kwesikulufu kunikezwa injini ye-servo, futhi amandla adluliswa ngokuvumelana phakathi kwakho kokubili, okungalawula inani lokuzungezisa ngezikulufu futhi kuthuthukise ukunemba kokuphakelayo. Umshayeli we-servo ushayela i-servo motor ukuze ajikelezise inombolo ehambisanayo yokujika ngokusekelwe kusignali yokufaka ye-PLC, futhi ushayela isikulufu ukuze sijikeleze ngebhande le-synchronous ukuqedela inqubo ngayinye yokugcwalisa nokondla.Lokhu kungalawula ngokunembile ukunemba kokugcwalisa ngakunye. impahla kuothomathikhi powder ukupakisha umshini
