"Gear pump oil leakage" zvinoreva kuti hydraulic oiri inopwanya skeleton mafuta seal uye inofashukira. Ichi chiitiko chinowanzoitika. Kubuda kwemafuta mumapombi egiya kunokanganisa zvakanyanya kushanda kwakajairwa kwemutakuri, kuvimbika kwepombi yegiya uye kusvibiswa kwezvakatipoteredza. Kuti ufambise mhinduro yedambudziko, zvinokonzeresa uye nzira dzekudzora dzekudonha kwemafuta kutadza kwegiya pombi mafuta chisimbiso zvinoongororwa.
1. Kufurira kwezvikamu zvekugadzira mhando
(1) Oil seal quality. Semuyenzaniso, kana iyo geometry yeoiri chisimbiso muromo isina kukodzera, chitubu chekusimbisa chakanyanya kusununguka, nezvimwewo, zvinokonzeresa kuvuza kwemhepo muyedzo yekusimba kwemhepo uye kubuda kwemafuta mushure mekunge pombi yegiya yaiswa muinjini huru. Panguva ino, chisimbiso chemafuta chinofanira kutsiviwa uye zvinhu uye geometry zvinofanirwa kuongororwa (mukana wemhando pakati pezvisimbiso zvemafuta epamba uye ekunze emberi zvisimbiso zvemafuta zvakakura).
(2) Kugadziriswa uye kusangana kwemapombi egiya. Kana paine matambudziko nekugadziriswa kwepombi yegiya uye kusangana, zvichikonzera kuti giya shaft yekutenderera nzvimbo ive kunze kwe concentricity nechekumberi kwevhavha kumira, zvinoita kuti chisimbiso chemafuta chipfeke eccentrically. Panguva ino, symmetry uye kutama kwechivharo chemberi chinotakura gomba kune gomba repini kunofanira kuongororwa, uye coaxiality ye skeleton mafuta chisimbiso kune gomba rinotakura rinofanira kuongororwa.
(3)Kuisa chisimbiso mhete zvinhu uye kugadzirisa mhando. Kana dambudziko iri riripo, mhete yekuisa chisimbiso ichatsemuka nekukweshwa, zvichiita kuti chisimbiso chechipiri chive chakasununguka kana kusashanda. Oiri yekudzvanya inopinda mune skeleton mafuta chisimbiso (yakaderera kumanikidza chiteshi), ichikonzera kubuda kwemafuta muchisimbiso chemafuta. Panguva ino, iyo yekuisa chisimbiso mhete zvinhu uye kugadzirisa mhando kunofanirwa kutariswa.
(4) Kugadziriswa kwemhando yepombi inoshanduka. Mhinduro kubva kuOEM inoratidza kuti giya pombi yemafuta chisimbiso yakasanganiswa neinosiyana yekumhanyisa pombi ine dambudziko rakakura rekudonha kwemafuta. Naizvozvo, kunaka kwekugadzirisa kwepombi yekumhanyisa inochinja zvakare kune hukuru hukuru pakudonha kwemafuta. Iyo pombi yekufambisa inoiswa pane inobuda shaft yegiya bhokisi, uye giya pombi inoiswa pane inobuda shaft yekutapurirana kuburikidza nekumisikidzwa kwepombi yekufambisa inomira. Kana iyo runout (verticality) yepombi yekufambisa inomira yakatarisana negear rotation centre iri kunze kwekushivirira (verticality), ichaitawo Iyo nzvimbo yekutenderera yegiya shaft uye yepakati pechisimbiso chemafuta hazvienderane, izvo zvinokanganisa kuiswa chisimbiso. . Munguva yekugadzira uye kuyedza kugadzirwa kwepombi yekumhanya inoshanduka, iyo coaxiality yenzvimbo yekutenderera kusvika pakumira uye kubuda kwechiso chekumira kunofanirwa kuongororwa.
(5) Iyo mafuta ekudzosa chiteshi chechivharo chepamberi pakati pechisimbiso chemafuta e skeleton uye mhete yekuisa chisimbiso cheCBG giya pombi haina kutsvedzerera, zvichiita kuti kumanikidza kuno kuwedzera, nekudaro kuputsa skeleton mafuta chisimbiso. Mushure mekuvandudzwa pano, iyo mafuta leakage phenomenon yepombi yakagadziridzwa zvakanyanya.
2. Pesvedzero yekuiswa kwemhando yepombi yegiya uye injini huru
(1) Kuiswa kunodiwa kwepombi yegiya uye injini huru inoda kuti coaxiality iri pasi pe0.05. Kazhinji pombi inoshanda inoiswa pane inoshanduka yekumhanyisa pombi, uye iyo inoshanduka yekumhanyisa pombi inoiswa pabhokisi regiya. Kana iyo yekubuda kweiyo yekupedzisira kumeso kwegiya bhokisi kana yekumhanyisa pombi iri pakati pekutenderera kwe spline shaft isisina kushivirira, chikanganiso chekuwedzera chinogadzirwa, zvichiita kuti pombi yegiya itakure radial simba pasi pekutenderera kwekumhanya, zvichikonzera mafuta. kuvuza muchisimbiso chemafuta.
(2) Kana kuiswa kwemvumo pakati pezvikamu zvine musoro. Kumira kwekunze kwepombi yegiya uye kumira kwemukati kwepombi yekutapurirana, pamwe neyekunze splines epombi yegiya uye masplines emukati egearbox spline shaft. Kunyangwe iyo clearance pakati pezviviri izvi zvine musoro ichave nemhedzisiro pakudonha kwemafuta epombi yegiya. Nokuti mukati uye kunze splines ndechenzvimbo yekumisikidza, iyo yakakodzera clearance haifanirwe kunge yakakura kwazvo; iyo yemukati nekunze splines ndeye chikamu chekutapurirana, uye iyo yakakodzera clearance haifanirwe kunge iri diki kuti ibvise kupindira.
(3) Kubuda kwemafuta mupombi yegiya kunoenderanawo nekiyi yayo ye spline roller. Sezvo kureba kwekubatana pakati pegiya pombi shaft yakawedzera splines uye gearbox inobuda shaft yemukati splines ipfupi, uye giya pombi inotumira torque hombe kana ichishanda, masplines ayo anotakura torque yakakwira uye anogona kutambura nekupfeka kweextrusion kana kutenderera, ichigadzira hombe. kupisa. , zvichikonzera kupisa uye kuchembera kwerubha muromo we skeleton mafuta chisimbiso, zvichikonzera kubuda kwemafuta. Zvinokurudzirwa kuti mugadziri mukuru weinjini atarise kusimba kwegiya pombi shaft yakatambanudzwa splines kana uchisarudza pombi yegiya kuti ive nechokwadi chakakwana chekubata kureba.
3. Kufurira kwemafuta e hydraulic
(1) Hutsanana hwehydraulic oiri hwakashata zvakanyanya, uye zvimedu zvekusvibisa zvakakura. Jecha uye welding slag mune akasiyana hydraulic control mavharuvhu uye mapaipi zvakare chimwe chezvikonzero zvekusvibisa. Nekuti gaka riri pakati peshaft dhayamita yegiya shaft negomba remukati remhete yechisimbiso idiki kwazvo, zvimedu zvakakura zvakasimba mumafuta zvinopinda mugedhi, zvichikonzera kupera nekukweshwa kwegomba remukati rechisimbiso kana kutenderera neshaft. , zvichiita kuti mafuta ekumanikidzwa kwechisimbiso chechipiri apinde munzvimbo yakaderera (Skeleton oil seal), zvichiita kuti chisimbiso chemafuta chiputsika. Panguva ino, iyo anti-kupfeka hydraulic oiri inofanirwa kusefa kana kutsiviwa neimwe nyowani.
(2) Mushure mekunge viscosity ye hydraulic mafuta yadzikira uye ichidzikira, oiri inova mutete. Pasi peiyo yepamusoro-kudzvanywa mamiriro epombi yegiya, iyo kuvuza kuburikidza neyechipiri chisimbiso gap inowedzera. Sezvo pasina nguva yekudzorera mafuta, kudzvinyirirwa munzvimbo yakaderera kunowedzera uye chisimbiso chemafuta chinoputsika. Zvinokurudzirwa kuedza mafuta nguva dzose uye kushandisa anti-wear hydraulic oil.
(3) Kana injini huru ikashanda pasi pemutoro unorema kwenguva yakareba uye mwero wemafuta mutangi remafuta wakadzikira, tembiricha yemafuta inogona kukwira kusvika 100 ° C, zvichiita kuti mafuta ave mutete uye skeleton mafuta seal lip kukwegura, nokudaro kukonzera kudonha kwemafuta; iyo tangi yemafuta yemafuta inofanirwa kuongororwa nguva nenguva kureba kwepamusoro kudzivirira kupisa kwakanyanya kwemafuta.
Kana uchida kutengaloader spare partspanguva yekushandiswa kweloader, unogona kutibvunza isu. Iwe unogona zvakare kutibata nesu kana iwe uchida kutenga aloader. CCMIE-inonyanya kuwanda mutengesi wezvigadzirwa zvemichina yekuvaka uye zvishongedzo.
