Mavharuvhu eglobe, mavharuvhu egedhi, mavharuvhu eshavishavi, mavharuvhu ekutarisa uye mavharuvhu ebhora zvese zvinhu zvakakosha mukudzora mumasisitimu akasiyana-siyana emapaipi nhasi. Vharuvhu yega yega yakasiyana pakutaridzika, chimiro uye kunyange kushandiswa kwayo. Zvisinei, vharuvhu yeglobe nevharuvhu yegedhi zvine zvimwe zvakafanana pakuonekwa, uye panguva imwe chete zvine basa rekutyora mupombi, saka pachava neshamwari dzakawanda dzisingabatani zvakanyanya nevharuvhu kuti dzivhiringidze zviviri izvi. Kutaura zvazviri, kana ukanyatsotarisa, musiyano uripo pakati pevharuvhu yeglobe nevharuvhu yegedhi uchiri mukuru.
- Maumbirwo
Kana nzvimbo yekuisa iri shoma, zvakakosha kutarisisa kusarudzwa kwe:
Vharuvhu yegedhi inogona kuvharwa zvakasimba nepamusoro pekuvhara nekushandisa kudzvanya kwepakati, kuitira kuti pasave nekubuda kwemvura. Pakuvhura nekuvhara, vharuvhu inodonhedzwa nepamusoro pekuvhara chigaro chevharuvhu zvinogara zvichisangana uye zvinokwizana, saka pamusoro pekuvhara zviri nyore kupfeka, uye kana vharuvhu yegedhi yava pedyo nekuvhara, musiyano wekumanikidzwa pakati pekumberi nekumashure kwepombi yakakura kwazvo, zvichiita kuti pamusoro pekuvhara upfeke zvakanyanya.
Maumbirwo evharuvhu yegedhi achave akaomarara kupfuura vharuvhu yeglobe, kubva pakuonekwa kwayo, kana iri caliber imwe chete, vharuvhu yegedhi yakakwira kupfuura vharuvhu yeglobe, uye vharuvhu yeglobe yakareba kupfuura vharuvhu yegedhi. Pamusoro pezvo, vharuvhu yegedhi yakakamurwa kuita tsvimbo yakajeka netsvimbo yerima. Vharuvhu yeglobe haina.
- Basa
Kana vharuvhu yepasi rose ikavhurwa uye yakavharwa, inenge iri mhando yetsinde rinokwira, kureva kuti, vhiri reruoko rinotenderedzwa, uye vhiri reruoko rinoita mafambiro ekutenderera nekusimudza pamwe chete netsinde revharuvhu. Vharuvhu yegedhi inofanira kutenderedza vhiri reruoko, kuitira kuti dzinde riite mafambiro ekusimudza, uye nzvimbo yevhiri reruoko pachayo irambe isina kuchinja.
Mwero wekuyerera kwemvura unosiyana, nemavharuvhu egedhi anoda kuvharwa zvizere kana zvakakwana, nepo mavharuvhu eglobe asina. Vharuvhu yeglobe ine gwara rakatarwa rekupinda nekubuda, uye vharuvhu yegedhi haina zvinodiwa zvekupinza nekuburitsa kunze kwenyika.
Pamusoro pezvo, vharuvhu regedhi rinongovhurwa zvizere kana kuvharwa zvizere chete, kuvhurwa nekuvharwa kwegedhi kwakakura kwazvo, nguva yekuvhurwa nekuvharwa yakareba. Kufamba kwevharuvhu regedhi remavharuvhu kudiki zvikuru, uye vharuvhu regedhi remavharuvhu rinogona kumira panzvimbo yakati kuti rigadzirise kuyerera kwemvura. Vharuvhu regedhi rinogona kungoshandiswa chete pakudimbura uye harina rimwe basa.
- Kushanda
Vharuvhu yeglobe inogona kushandiswa pakucheka nekudzora kuyerera kwemvura. Kusapindirana kwemvura kwevharuvhu yeglobe kwakakura, uye zvinonetsa kuvhura nekuvhara, asi nekuda kwekuti vharuvhu iri pfupi kubva pamusoro pekuvhara, kuvhura nekuvhara kupfupi.
Nekuti vharuvhu regedhi rinogona kuvhurwa zvizere uye kuvharwa zvizere chete, kana ravhurwa zvizere, kuramba kwemvura iri pakati nepakati mugwara remuviri wevharuvhu kunenge kuri 0, saka kuvhurwa nekuvharwa kwevharuvhu regedhi kuchachengetedza basa zvakanyanya, asi ndiro yegedhi iri kure nenzvimbo yekuvhara, uye nguva yekuvhurwa nekuvharwa yakareba.
- Kuiswa uye kuyerera kwenzira
Mhedzisiro yevharuvhu yegedhi inoyerera kumativi ese maviri yakafanana, uye hapana chinodiwa chekupinda nekubuda kwekuisa, uye medium inogona kuyerera kumativi ese maviri. Vharuvhu yeglobe inofanirwa kuiswa zvichienderana negwara rechiratidzo chemuseve wevharuvhu, uye pane gwara rakajeka pagwara rekupinda nekuburitsa vharuvhu yeglobe, uye gwara rekufamba kwevharuvhu yeglobe "three to" muChina rinobva kumusoro kusvika pasi.
Vharuvhu yepasi rose iri pasi uye yakakwira, uye kubva kunze kune mapaipi ari pachena asiri padanho rechikamu. Chinomhanyisa vharuvhu yepasi rose chiri pamutsetse wakatwasuka. Kurova kwevharuvhu yepasi rose kwakakura kupfuura kwevharuvhu yepasi rose.
Kubva pamaonero ekudzivirira kuyerera kwemvura, kudzivirira kuyerera kwevharuvhu regedhi kudiki kana rakavhurika zvizere, uye kudzivirira kuyerera kwevharuvhu rinomira mutoro kwakakura. Kudzivirira kuyerera kwevharuvhu regedhi rakajairika kunenge 0.08 ~ 0.12, simba rekuvhura nekuvhara diki, uye medium inogona kuyerera nemativi maviri. Kudzivirira kuyerera kwevharuvhu remavharuvhu akajairwa kunopera ka3-5 kupfuura mavharuvhu egedhi. Pakuvhura nekuvhara, zvakakosha kumanikidza kuvharwa kuti chisimbiso chisvike, vharuvhu inodonhedzwa nevharuvhu regedhi inongobata chete nepamusoro pechisimbiso kana yavharwa zvachose, saka kupera kwenzvimbo yechisimbiso kudiki kwazvo, nekuti kuyerera kwesimba guru kunoda kuwedzera actuator. Vharuvhu regedhi rinofanira kutarisisa kugadziriswa kwe torque control mechanism.
Vharuvhu yepasi rose ine nzira mbiri dzekuisa, imwe ndeyekuti medium inogona kupinda kubva pasi pevharuvhu, mukana ndewekuti kana vharuvhu yavharwa, kurongedza hakusi pasi pekumanikidzwa, hupenyu hwebasa rekurongedza hunogona kuwedzerwa, uye basa rekutsiva kurongedza rinogona kuitwa pasi pekumanikidzwa mupaipi iri pamberi pevharuvhu; dambudziko nderekuti torque inotyaira yevharuvhu yakakura, inova kanenge kamwe chete kupfuura kuyerera kwepamusoro, uye simba re axial revharuvhu diki rakakura, uye vharuvhu diki iri nyore kukotama.
Saka, nzira iyi inowanzo shandiswa chete kumavharuvhu eglobe ane dhayamita diki (DN50 kana pasi), uye mavharuvhu eglobe ari pamusoro peDN200 anosarudzwa kuti apinde nepakati kubva kumusoro. (Mavharuvhu emagetsi anowanzo shandisa nzira yekupinda nayo kubva kumusoro.) Dambudziko rekupinda nepakati kubva kumusoro rakasiyana chaizvo nekupinda kwaanoita pasi.
- Kuvhara
Kuvhara pamusoro pevharuvhu yepasi rose idivi diki retrapezoidal repakati pevharuvhu (tarisa chimiro chepakati pevharuvhu), kana perivhu yadonha, inofanana nekuvharwa kwevharuvhu (kana musiyano wekumanikidzwa uri mukuru, hongu, kuvharwa hakusi kwakasimba, asi mhedzisiro yekudzokera shure haina kuipa), vharuvhu yepasi rose yakavharwa nedivi replate yepakati pevharuvhu, mhedzisiro yekuvharwa haina kunaka sevharuvhu yepasi rose, uye perivhu yepasi rose haizodonhe sevharuvhu yepasi rose.
