Pombi yemuchina inonziwo pombi yepamberi pedanho, uye ndeimwe yemapombi evacuum anoshandiswa zvakanyanya, anoshandisa oiri kuchengetedza simba rekuvhara uye anoshandisa nzira dzemuchina kuti arambe achichinja huwandu hwenzvimbo inosveta mupombi, kuitira kuti huwandu hwegasi riri mumudziyo unopombwa hurambe huchiwedzera kuti huwane vacuum. Kune mhando dzakawanda dzemapombi emuchina, akajairika ndeaya: slide valve type, piston reciprocating type, fixed vane type uye rotary vane type.
Zvikamu zvepombi dzemakanika
Pombi yemuchina inowanzo shandiswa kupomba mhepo yakaoma, asi haikwanise kupomba okisijeni yakawanda, magasi anoputika uye anoparadza, mapombi emuchina anowanzo shandiswa kupomba gasi risingaperi, asi hapana zvazvinobatsira pamvura negasi, saka haikwanise kupomba mvura negasi. Zvikamu zvinotamba basa guru mupombi yerotary vane stator istator, rotor, shrapnel, nezvimwewo. Rotor iri mukati me stator asi ine axis yakasiyana ne stator, senge madenderedzwa maviri emukati ane tangent, rotor slot ine zvidimbu zviviri zve shrapnel, pakati pezvidimbu zviviri zve shrapnel pane chitubu chekuona kuti shrapnel yakabatana zvakasimba nemadziro emukati me stator.
Musimboti wekushanda kwepombi yemakanika
Zvimedu zvayo zviviri zvinotamba mabasa maviri, kune rumwe rutivi, zvichisveta gasi kubva mugomba, uye kune rumwe rutivi, zvichidzvanya gasi ratopinda uye zvichiburitsa gasi kubva mupombi. Pakutenderera kwese, pombi inopedza kusveta kaviri uye kusveta kaviri.
Kana pombi ichitenderera newachi nguva dzose, pombi inotenderera ine vane inoramba ichidhonza gasi kuburikidza nekupinda kwayo uye inoriburitsa kubva pachiteshi chekubuda mweya kuti ibudirire chinangwa chekupomba mudziyo. Kuti pave nekushanda zvakanaka kwepombi, pombi stator inonyudzwa mumafuta kuitira kuti nzvimbo dzinenge dzakavharwa nenzvimbo dzine njodzi munzvimbo imwe neimwe dzigare dzakakwana kuti dzizadze nzvimbo dzine njodzi, saka mafuta anoita basa rekuzora kune rumwe rutivi, uye kune rumwe rutivi, anoita basa rekuvhara nekuvhara nzvimbo dzine njodzi kudzivirira mamorekuru egasi kuti asadzokere kumashure kuburikidza nenzira dzakasiyana-siyana kuenda kunzvimbo ine kumanikidzwa kwakaderera.
Mhedzisiro yekudzika kwepombi yemakanika ine chekuitawo nekumhanya kwemota uye kusimba kwebhandi, kana bhandi remota rakasununguka, kumhanya kwemota kunononoka, mhedzisiro yekudzika kwepombi yemakanika ichavawo yakaipa, saka tinofanira kugara tichiichengetedza, kutarisa nzvimbo, mhedzisiro yekudzika kwemafuta emakanika yepombi inofanirawo kuongororwa kakawanda, mafuta mashoma, haigone kusvika pamhedzisiro yekudzika, pombi ichadonha, mafuta akawandisa, gomba rekukweva rakavharwa, harigone kusveta mweya nemhepo, kazhinji, padanho remafuta 0.5 cm pasi pemutsetse unogona kuva.
Pombi yemidzi ine pombi yemuchina sepombi yepamberi
Pombi yemidzi: Ipombi yemuchina ine marotor maviri kana akawanda anotenderera nekumhanya kwakanyanya. Sezvo musimboti wayo wekushanda wakafanana neweRoots blower, inogonawo kunzi Roots vacuum pump, ine kumhanya kukuru kwekupomba muhuwandu hwekumanikidzwa kwe100-1 Pa. Inogadzirisa zvikanganiso zvekusakwana kwesimba repombi yemuchina muhuwandu hwekumanikidzwa uku. Pombi iyi haigone kutanga kushanda kubva mumhepo, uye haigone kuburitsa mweya zvakananga, basa rayo nderekuwedzera musiyano wekumanikidzwa pakati penzvimbo yekupinda neyokubuda, chimwe chinodiwa kuti pombi yemuchina ipedzise, saka, inofanira kunge yakashongedzwa nepombi yemuchina sepombi yekutanga.
Kungwarira uye kugadziriswa kwemapombi emakanika
Pakushandisa pombi dzemakanika, zvinhu zvinotevera zvinofanira kucherechedzwa.
1, Pombi yemuchina inofanira kuiswa munzvimbo yakachena uye yakaoma.
2, Pombi inofanira kucheneswa uye yakaoma, mafuta ari mupombi ane simba rekuvhara uye kudira mafuta, saka anofanira kuwedzerwa zvichienderana nehuwandu hwakatarwa.
3, Kuti mafuta epombi atsiviwe nguva dzose, kana uchitsiva mafuta ekare, unofanira kutanga watanga wabuda, nguva yacho isingasviki mwedzi mitatu kusvika kumwedzi mitanhatu kuti utsiviwe kamwe chete.
4, Tevedzera mirairo yekubatanidza waya.
5, Pombi yemuchina inofanira kuvhara vharuvhu yekupinda mweya isati yamira kushanda, yobva yadzima yovhura vharuvhu yemhepo, mweya wobva wapinda nepapombi uchipinda nepapombi.
6, Kana pombi iri kushanda, tembiricha yemafuta haifanirwe kupfuura 75℃, zvikasadaro ichave diki zvakanyanya nekuda kwekunaka kwemafuta uye zvichiita kuti avharwe zvisina kunaka.
7, Tarisa kusimba kwebhandi repombi yemakanika, kumhanya kwemota, kumhanya kwemota yeRoots pump, uye kushanda kweseal ring nguva nenguva.
–Chinyorwa ichi chakaburitswa neGuangdong Zhenhua Technology, kambani inogadzira michina yekuputira vacuum.
