Imwe chip vacuum jenareta CTA (B)-B ine mbiri yekuyeresa zviteshi

Ongororo yekusveta kuita kwevacuum jenareta

1. Main performance parameters yevacuum generator

① Kushandiswa kwemhepo: kunoreva kuyerera kweqv1 kuyerera kubva mumuromo.

② Suction flow rate: inoreva kuyerera kwemhepo qv2 inofemerwa kubva pachiteshi chekukwevera.Kana chiteshi chekukweva chavhurika kumhepo, kuyerera kwayo kuyerera ndiyo hombe, inodaidzwa kuti yakanyanya kuyamwa kuyerera mwero qv2max.

③ Dzvinyiriro pachiteshi chekuyamwa: yakanyorwa sePv.Kana chiteshi chekusveta chikavharwa zvachose (semuenzaniso dhisiki rekusveta rinosveta workpiece), ndiko kuti, kana kuyerera kuri zero, kudzvanywa muchiteshi chekusveta ndiyo yakaderera, yakanyorwa sePvmin.

④ Nguva yekupindura: Suction yekupindura ndiyo yakakosha parameter inoratidza kushanda kwevacuum jenareta, iyo inoreva nguva kubva pakuvhurwa kwevharuvhu yekudzosera kusvika painodiwa vacuum degree mu system loop.

2. Zvinhu zvikuru zvinokanganisa kushanda kwevacuum generator

Kuita kwevacuum jenareta kune chekuita nezvakawanda zvinhu, senge hudiki dhayamita yemhino, chimiro uye dhayamita yechibvumirano uye diffusion chubhu, chinzvimbo chayo chinowirirana uye kudzvanywa kwegasi sosi.Mufananidzo 2 igirafu rinoratidza hukama pakati pekusveta inlet pressure, kusveta kuyerera kwemhepo, kushandiswa kwemhepo uye kupa kumanikidzwa kwevacuum generator.Zvinoratidza kuti kana kudzvinyirirwa kwekupa kunosvika kune imwe kukosha, kusveta inlet pressure yakaderera, uye ipapo kusveta kuyerera kunosvika pakakwirira.Kana iyo yekumanikidza yekugovera ichiramba ichiwedzera, iyo yekuyamwa inlet pressure inowedzera, uye ipapo kuyerera kuyerera kunoderera.

① Kuongororwa kwehunhu hwehupamhi hwekusveta kuyerera qv2max: Iyo yakakodzera qv2max hunhu hwevacuum jenareta inoda kuti qv2max iri pamutengo wepamusoro mukati mehuwandu hweakajairwa suction pressure (P01 = 0.4-0.5 MPa) uye inoshanduka zvakanaka neP01.

(2) Kuongororwa kwehunhu hwekumanikidza Pv pachiteshi chekukwevera: Yakanaka Pv hunhu hwevacuum jenareta inoda kuti Pv iri pamutengo wakaderera mukati mehuwandu hwehuwandu hwekupa kumanikidza (P01 = 0.4-0.5 MPa) uye inoshanduka zvakanaka ne Pv1.

(3) Pasi pemamiriro ekuti ruzha rwekusveta rwakavharwa zvachose, hukama huri pakati pekumanikidzwa kwePv panzvimbo yekusveta uye kuyerera kwekuyerera pasi pemamiriro ezvinhu chaiwo kunoratidzwa mumufananidzo 3. Kuti uwane hukama hwakanaka hunofananidza pakati pekumanikidzika. pakusveta inlet uye kuyerera kweyero, multistage vacuum jenareta inogona kugadzirwa kuti ibatanidzwe munhevedzano.
