Kushanda kwekuchera kunogona kunyatsojeka here? Uyu mubvunzo wagara uchinetsa vashandisi vazhinji nenyanzvi dzeindasitiri muindasitiri yemichina yekuvaka. Zvino, Ningbo Flag-kumusoroHydraulics Co., Ltd., ine ruzivo rwemakore anopfuura gumi mubasa re hydraulics, yakapindura mubvunzo uyu nekugadzira kwayo itsva ye generation pilot control valves yakazvimiririra. Mavharuvhu aya haangogonese kushanda nemazvo chete, asiwo kunzwisisika, kushanda zvakanaka, uye kugara kwenguva refu. Sekambani inotungamirwa ne tekinoroji yakavambwa muna 2010 muNingbo Wangchun Industrial Park, Ningbo Flag.-kumusoroHydraulics yagara ichitevedzera pfungwa ye "kugadzira zvinhu zvitsva uye kugadzira zvinhu zvisina tsarukano." Kuburitswa kwechizvarwa chitsva ichi chemavharuvhu ekudzora emutyairi kunoratidza hunyanzvi hwayo hwetekinoroji uye ruzivo rwemusika.
Kubudirira kutsva mukudzora nemazvo: Kuvandudzwa kwakazara kubva pahunyanzvi hwehunyanzvi kuenda kuruzivo rwekushanda.
Kunyatsojeka kwechizvarwa chitsva ichi chemavharuvhu ekudzora mapilot kunobva kuNingbo Flag-kumusoroKugadziriswa kwakadzama kweHydraulics muhunyanzvi hwayo hwepamusoro. Chigadzirwa ichi chinoshandisa tekinoroji yekambani yemazuva ano yehigh-response proportional control, ichishandisa hunyanzvi hwepamusoro hweR&D center hunosanganisira "design calculation + host system simulation + hydraulic system simulation" kuti iwedzere kuyerera uye kumanikidzwa. Kumanikidzwa kwayo kwakaganhurirwa kunoramba kwakagadzikana pa35 bar, uye kuyerera kwayo kwakaganhurirwa kunogona kugadziriswa nemazvo kusvika 15-20 L/min zvichienderana nemamiriro ekushanda. Hurefu hwayo hwekuchinjika pakupisa kwemafuta hunotangira pa -20°C kusvika 80°C, zvichiita kuti kutonga kushande zvakanaka kunyangwe munzvimbo dzakanyanya kuvaka.
Pamusoro pezvo, chigadzirwa ichi chine chinhu cheHall effect chakanyatsojeka (voltage 12VDC yakayerwa) uye switch yeIP67-rated pushbutton (3A/28VDC), zvichibvumira kutora mirairo yekushanda panguva chaiyo uye mhinduro nekukurumidza. Pamwe chete nekugadzirisa kwakanyatsojeka kwedisplacement-pressure curve yemaburi 1-4 (semuenzaniso, mubato wepilot weB-type unopa kururamisa kwekudzora kudzvanywa kwe0.5±0.2 bar), izvi zvinopa ruzivo rwekudzora rwakanyatsojeka uye rwakagadzikana. Kungave kuita mabasa ekunyatsojeka akadai sekuisa pombi uye kugadzira slope munzvimbo dzakamanikana, kana kusimudza nekutenderedza mitoro inorema munzvimbo dzakaoma, vharuvhu iyi inotumira nemazvo chinangwa chega chega chekushanda, ichinyatsoita kuti "maoko afambe, muchina unotevera moyo."
Zvakakosha kuti, kuti ive nechokwadi chekuti chigadzirwa chacho chakanyatsorongeka, Ningbo Flag -upHydraulics inoshandisa michina yekugadzira zvigadzirwa zvekunze kwenyika mukugadzirwa kwayo. Chimiro chemuviri wevharuvhu chinogadziriswa kuburikidza nekuongorora kwechimiro, uye zvigadzirwa zvese zvakaunganidzwa zvinoedzwa nefekitori 100%. Ruzivo rwese rwekuyedza runochengetwa panguva chaiyo pasevha yekombuta, zvichiita kuti parameter yekushanda kwechigadzirwa chega chega isvike padanho rekugadzira uye kubvisa kutsauka kwakarurama kubva panobva.
Kugadzira Hydraulic Kunoshanda Uye Kuchengetedza Simba: Kugadzirisa Kushanda Pamwe Chete kweValve Spool neOiri Circuit
Zvichibva pakudzora kwakarurama, chizvarwa chitsva chemavharuvhu ekudzora emutyairi anotarisa zvakanyanya pane zvinodiwa zvikuru zve "kushanda zvakanaka uye kuchengetedza simba." Nekugadzirisa chimiro chevharuvhu uye marongerwo edunhu remafuta, timu yeR&D inodzora zvakasimba kumanikidzwa kweT-port kumashure mukati memabhawa matatu, zvichideredza zvakanyanya kurasikirwa kwekuyerera. Zvichienzaniswa nezvigadzirwa zvechinyakare, kushandiswa kwekuyerera kunovandudzwa neinenge 15%, zvichivimbisa simba rakakwana rekuchekerera uku zvichideredza kushandiswa kwesimba re hydraulic system. Mumashandisirwo anoshanda, dhizaini iyi inopa vashandisi mabhenefiti maviri. Chekutanga, kushanda kwepamusoro kwekuyerera kunowedzera zvakananga kumhanya kwekuvaka. Semuenzaniso, mumabasa ekufambisa pasi, nguva yekusimudza mabhaketi uye kutenderera kwedenderedzwa zvinopfupikiswa, zvichiwedzera kugadzirwa kwezuva nezuva ne8%-10%. Chechipiri, kushandiswa kwesimba kuderedzwa zvisina kunanga kunoderedza kushandiswa kwemafuta einjini. Pamwe chete nekuenderana kwechigadzirwa nemazinga ekuchena kwemafuta (NAS level 8 kana pasi), izvi zvinoderedza kutadza kwehurongwa hwe hydraulic kunokonzerwa nekusvibiswa kwemafuta. Nekufamba kwenguva, izvi zvinogona kuchengetedza vashandisi 15%-20% mumari yemafuta nekugadzirisa, zvichizadzisa zvakakwana kudiwa kwemusika kwekudzikisa mitengo uye kuvandudza kushanda zvakanaka kwemichina yekuvaka.
Kugara kwenguva refu uye nyore kugadzirisa: Dhizaini yakagadzirirwa mamiriro enzvimbo yekuvaka
Tichifunga nezvenzvimbo dzinonyanya kupfekwa uye dzinotakura zvinhu zvakawanda dzinowanikwa nevacheri panzvimbo dzekuvaka, Ningbo Flag-up Hydraulics yakagadzirisa zvinhu zvakanangana nekugadzirwa kwemavharuvhu ayo matsva emuchina wekudzora mapilot. Muviri wemavharuvhu wakagadzirwa nesimbi yesimbi isingapfekwi, uye michina yekuchenesa nekuongorora inounzwa kunze kwenyika inoita kuti zvikamu zvive nemazvo. Pamwe chete nekugadzirwa kwepamusoro kweanodized, izvi zvinowedzera ngura uye kuramba kupfeka. Zvichienderera mberi nepfungwa yekambani yekugadzira modular, chigadzirwa ichi chinoshandisa standardized G1/4EO (O-ring seal) kana JIS B2351 G1/4 ports. Izvi zvinobvumira kugadziriswa nekukurumidza uye kutsiviwa kwezvikamu, zvichideredza kunonoka kunokonzerwa nekusashanda kwemidziyo.
Uyezve, kugara kwenguva refu kwechigadzirwa ichi kunoonekwa nekunyatsotarisa zvakadzama. Semuenzaniso, central rotary joint (inoshandiswa ne pilot control valve) ine simba guru rekushanda rinosvika 30 MPa uye test pressure inosvika 35 MPa. Ine simba rekutanga rinosvika ≤150 N·m uye rotational torque inosvika ≤100 N·m. Izvi zvinoita kuti ikwanise kutsungirira kukanganiswa kwekufamba kwenguva refu mu excavators, zvichiwedzera hupenyu hwayo hwebasa neanopfuura 20% zvichienzaniswa neavhareji yeindasitiri, zvichideredza mari yekutsiva yeramangwana kune vashandisi. Kusimudzira Kuvandudzwa Kweindasitiri: Kubva paDomestic Benchmark kuenda kuGlobal Competitiveness
Sekambani ine tekinoroji yepamusoro inonyanya kushandisa zvikamu zve core hydraulic system, zvigadzirwa zveNingbo Flag-up Hydraulics zvagara zvichishandiswa zvakanyanya mumichina yekuvaka, michina yekuchera marasha, michina yechiteshi, nedzimwe nzvimbo. Kutangwa kwechizvarwa chitsva ichi chemavharuvhu ekudzora mapilot idanho guru muchinangwa chayo chekuva kambani inoyera zvikamu zve core muindasitiri yemidziyo yeChina. Chigadzirwa ichi chakatopasa bvunzo dzekutevera mitemo nemakambani makuru eOEM akadai seXCMG, Liugong, Sunward Intelligent, neLovol Heavy Industry, uye munguva pfupi iri kutevera chichagadzirwa zvakawanda kuti chishandiswe mumhando dzakasiyana-siyana dzema excavator.
Chikwata cheNingbo Flag-up Hydraulics R&D chakati chizvarwa chitsva ichi chemavharuvhu ekudzora mapilot hachingosanganisi chete zvinodiwa nezvinodiwa zvemuno, zvinosanganisira GB/T19674 neISO1179, asiwo chinosvika padanho repamusoro-soro repasi rose rekuita nemazvo, kushanda zvakanaka, uye kugara kwenguva refu. Zvichienderera mberi, kambani iyi icharamba ichishandisa kugona kwayo kugadzira nzvimbo yayo yekugadzira inosvika 20,000 square metres uye sisitimu yayo yesevhisi inosanganisira "tsvakiridzo yevatengi, tsvakiridzo yemakwikwi, uye kuvandudzwa kwemusika" kuti ipe vashandisi vepasi rose mhinduro dzepamusoro dzekudzora mahydraulic, zvichibatsira indasitiri yemichina yekuvaka kukurumidzisa kusimudzira kwayo kune tekinoroji dzakangwara, dzinoshandisa simba shoma, uye dzakavimbika zvikuru. Kubva pakuenzanisa kwema laboratori kusvika pakusimbiswa panzvimbo, Ningbo Flag-up Hydraulics yakaratidza nevharuvhu yayo yekudzora mapilot yechizvarwa chinotevera kuti kushanda kwekugadzira mapilot nemazvo hakusi kungoitika muindasitiri chete asiwo tekinoroji inoshanda, inogoneka, uye inogona kudzokororwa. Ichitungamirirwa netsika yayo yemakambani inotarisa vanhu, kambani iyi yehydraulics iri muNingbo iri kugadzira kukosha kukuru kune vashandisi vemichina yekuvaka yepasi rose kuburikidza nekuvandudza tekinoroji nguva dzose.
