Zvishandiso zvemvura ring vacuum pombi

1. Basic mhando uye maitiro.

Pombi dzemhete dzemvura dzinogona kukamurwa kuita mhando dzinotevera maererano nemaitiro akasiyana.

■ Single-stage single-acting water mhete pombi: single-stage zvinoreva kuti pane imwe chete impeller, uye single-acting zvinoreva kuti iperesi inotenderera kamwe chete pavhiki, uye kusveta uye kupera kunoitwa kamwe chete.Iyo yekupedzisira vacuum yepombi iyi yakakwira, asi kumhanya kwekupomba uye kugona kwakadzikira.

■ Single-stage-double-acting water mhete pombi: imwe-nhanho inoreva imwe chete inofambisa, kaviri-kuita zvinoreva kuti vhiki imwe neimwe impeller inotenderera, kusveta uye kupera kunoitwa kaviri.Mumamiriro akafanana ekumhanya kwepombi, kaviri-inoita mvura mhete pombi pane imwechete-inobata mvura yepombi yemhete inoderedza zvakanyanya saizi nehuremu.Sezvo kamuri yekushanda yakagoverwa kumativi ose epombi hub, mutoro unoshanda pa rotor unovandudzwa.Kumhanya kwekupomba kwerudzi urwu rwepombi kwakakwira uye kushanda kwacho kwakakwira, asi iyo yekupedzisira vacuum yakaderera.

■ Mapombi emvura ane maviri-danho remvura: Mapombi mazhinji emvura ane maviri-nhanho ari maviri-anobata pombi munhevedzano.Muchidimbu, maviri-chikamu chimwe-chinoita mvura mhete pombi impellers inogovera yakajairika mandrel yekubatanidza.Chinhu chayo chikuru ndechekuti ichiri nehombe yekupomba kumhanya padanho repamusoro revacuum uye yakagadzikana yekushanda mamiriro.

■ Pombi yemhete yemvura yemumhepo: Pombi yerin'i yemvura yemuchadenga inenge iri seti yemaejector emuchadenga akatevedzana ane pombi yemhete yemvura.Pombi yemhete yemvura yakabatanidzwa munhevedzano nepombi yemuchadenga pamberi pepombi yemhete yemvura kuitira kuti iwedzere vacuum yekupedzisira uye kuwedzera huwandu hwekushandiswa kwepombi.

Pombi dzemhete dzemvura dzine zvinotevera zvakanakira zvichienzaniswa nemamwe marudzi emakanika vacuum pombi.

▪ Chimiro chakareruka, kuderera kwekugadzira zvinodiwa, zviri nyore kugadzirisa.Kushanda kuri nyore uye kugadzirisa kuri nyore.

▪ Compact structure, pombi inowanzobatanidzwa zvakananga kumota uye ine high rpm.Nezvimiro zvidiki zvimiro, vhoriyamu yakakura yekuburitsa inogona kuwanikwa.

▪ Hapana simbi inokweshana munzvimbo yepombi, hapana kukwirisa kwepombi kunodiwa.Kuiswa chisimbiso pakati pezvikamu zvinotenderera uye zvakagadziriswa zvinogona kuitwa zvakananga nechisimbiso chemvura.

▪Kuchinja kwetembiricha yegasi rakatsikirirwa muimba yepombi idiki zvikuru uye inogona kunzi isothermal compression, saka magasi anopisa uye anoputika anogona kupomba kunze.

▪Kusavepo kwevharuvhu yekuburitsa nekukwesha kunoita kuti pombi ibvise magasi ane guruva, magasi anogona kukoneswa uye misanganiswa yemvura-yegasi.

2 Kuipa kwepombi dzemhete dzemvura.

▪ Kusashanda zvakanaka, kazhinji kunosvika 30%, zviri nani kusvika pa50%.

▪ Vacuum yakaderera.Izvi hazvisi chete nekuda kwezvimiro zvinogumira, asi zvakanyanya kukosha, neiyo inoshanda fluid saturation vapor pressure.

Kazhinji, pombi dzemhete dzemvura dzinoshandiswa zvakanyanya nekuda kwezvakanaka zvadzo zvakaita sekudzvanya kweisothermal uye kushandiswa kwemvura semvura yekuisa chisimbiso, mukana wekupomba magasi anopisa, anoputika uye anoparadza, uye zvakare mukana wekupomba magasi ane guruva uye. mwando.

4 Pfungwa huru pakusarudza

I. Kutsunga rudzi rwepombi yemvura ring vacuum pump

Mhando yemvura ring vacuum pombi inonyanya kutsanangurwa nepombi yepakati, iyo inodiwa gasi vhoriyamu, vacuum degree kana exhaust pressure.

II.Chechipiri, pombi yemvura ring vacuum pombi inoda kuterera kune mapoinzi maviri mushure mekushanda kwakajairika.

1, Sezvingabvira, iyo vacuum level yepombi yakasarudzwa yevacuum inodiwa kuti ive mukati menzvimbo yepamusoro inoshanda, ndiko kuti, kushanda munzvimbo yeyakakosha inodiwa vacuum level kana yakakosha inodiwa yekumanikidza kumanikidza, kuitira kuti uve nechokwadi. kuti pombi yevacuum inogona kushanda zvakajairwa zvinoenderana nezvinodiwa uye zvinodiwa.Kushanda padhuze nehupamhi hwevacuum level kana yakanyanya kupera yekumanikidza huwandu hwepombi yevacuum inofanira kudzivirirwa.

Kushanda munzvimbo iyi hakusi kungonyanya kusashanda, asi zvakare kusagadzikana kwakanyanya uye kunoda kuzunguzika uye ruzha.Kumapombi ekuputira ane high vacuum level, achishanda mukati meiyi nzvimbo, cavitation inowanzoitikawo, iyo inoratidzwa neruzha uye kudengenyeka mukati mepombi yevacuum.Kuwedzeredza cavitation kunogona kutungamirira kukuvadza kumuviri wepombi, impeller uye zvimwe zvikamu, kuitira kuti pombi yevacuum isashande zvakanaka.

Zvinogona kuoneka kuti kana vacuum kana gasi rinodiwa nepombi yekuputira isiri yakakwirira, kukoshesa kunogona kupiwa kune imwe-nhanho pombi.Kana iyo inodiwa yedhigirii yevacuum kana gasi kudzvanywa kwakakwira, imwe-nhanho pombi kazhinji haigone kusangana nayo, kana, chinodiwa chepombi chichiri nehombe yegesi vhoriyamu kana iri yepamusoro vacuum degree, ndiko kuti, chinodiwa chekuita curve. iri flatter mune yakakwira vacuum degree, maviri-nhanho pombi inogona kusarudzwa.Kana iyo vacuum inodiwa iri pamusoro -710mmHg, Roots mvura ring vacuum unit inogona kushandiswa sedhiza yekupomba.

2, Nemazvo sarudza pombi yevacuum zvinoenderana neinodiwa yekupomba simba rehurongwa

Kana rudzi rwepombi yevacuum kana unit unit yakasarudzwa, iyo yakakodzera modhi inofanira kusarudzwa maererano neinodiwa yekupomba simba rehurongwa.

Hunhu hwemhando dzakasiyana dzemvura ring vacuum pumps ndedzinotevera.
