Ijeneretha ye-vacuum ye-chip eyodwa CTA(B)-E enezimbobo zokulinganisa ezimbili

I-vacuum generator iyisici esisha, esisebenzayo, esihlanzekile, esongayo nesincane esisebenzisa umthombo womoya ocindezelayo ukuze kukhiqizwe umfutho ongemuhle, okwenza kube lula kakhulu futhi kube lula ukuthola ingcindezi engalungile lapho kunomoya ocindezelweyo noma lapho kokubili ukucindezela okuhle nokubi. ziyadingeka ohlelweni lwe-pneumatic. Amajeneretha e-vacuum asetshenziswa kakhulu emishinini, e-elekthronikhi, ekupakisheni, ekuphrinteni, kumapulasitiki kanye namarobhothi kuma-automation ezimbonini.

Ukusetshenziswa okujwayelekile kwe-vacuum generator ukusebenzisana kwe-vacuum sucker ukukhangisa nokuthutha izinto ezihlukahlukene, ezifanele kakhulu ukukhangisa izinto ezithambile, ezithambile nezingezona ezensimbi noma izinto eziyindilinga. Kulolu hlobo lwesicelo, isici esivamile ukuthi isizinda somoya esidingekayo sincane, i-vacuum degree ayiphezulu futhi isebenza ngezikhathi ezithile. Umbhali ucabanga ukuthi ukuhlaziya kanye nocwaningo mayelana nendlela yokumpompa i-vacuum generator kanye nezici ezithinta ukusebenza kwayo kubaluleke kakhulu ekwakhiweni nasekukhethweni kwamasekethe e-compressor positive kanye nebi.

Okokuqala, isimiso sokusebenza se-vacuum generator

Umgomo wokusebenza we-vacuum generator ukusebenzisa umbhobho ukufafaza umoya ocindezelwe ngesivinini esikhulu, wenze ijethi endaweni yokukhipha umlomo, futhi ukhiqize ukugeleza kokungena. Ngaphansi komthelela wokungena, umoya ozungeze i-nozzle ephumayo uyamuncwa ngokuqhubekayo, ukuze ukucindezela endaweni ye-adsorption yehliswe ibe ngaphansi kokucindezela komkhathi, futhi kwakheka izinga elithile le-vacuum.

Ngokuvumelana ne-fluid mechanics, ukuqhubeka kwesibalo segesi yomoya engenakucindezelwa (igesi iqhubekela phambili ngesivinini esiphansi, esingathathwa cishe njengomoya ongenakucindezelwa)

A1v1= A2v2

Lapho i-A1, i-a2-indawo ephambanayo yepayipi, m2.

I-V1, i-V2-isivinini sokugeleza komoya, m/s

Kusukela kufomula engenhla, kungabonakala ukuthi isigaba sesiphambano siyanda futhi isivinini sokugeleza siyancipha; Ingxenye yesiphambano iyancipha futhi isivinini sokugeleza siyanda.

Ngamapayipi avundlile, i-Bernoulli efanelekile yamandla equation yomoya ongenakucindezelwa

P1+1/2ρv12=P2+1/2ρv22

Lapho i-P1, i-P2-ingcindezi ehambisana nezigaba A1 ne-A2, Pa

I-V1, i-V2-isivinini esihambelanayo ezigabeni A1 ne-A2, m/s

ρ-ukuminyana komoya, kg/m2

Njengoba kungabonakala kufomula engenhla, ingcindezi iyancipha ngokunyuka kwezinga lokugeleza, kanye ne-P1 >> P2 lapho i-v2 >> v1. Uma i-v2 ikhuphuka ibe yinani elithile, i-P2 izoba ngaphansi kokucindezela okukodwa komkhathi, okungukuthi, ukucindezela okungalungile kuzokwenziwa. Ngakho-ke, ukucindezela okungalungile kungatholakala ngokwandisa izinga lokugeleza ukukhiqiza ukumunca.
