Pombi yekongirivharafukudzora kongiri pombi rori hydraulic system kana wasangana nekutadza maitiro ekuita nayo?
Kusanganisa redunhu sisitimu inoshandiswa zvakanyanya mukongiri pombi parizvino. Iyo sisitimu ine yekubatsira pombi (giya pombi), superimposed vharafu yekuyamura, pressure relay, electromagnetic reversing valve uye maviri-nzira hydraulic mota. Kusanganisa oiri yakakwira kudzvinyirirwa kunodzorwa ne stack overflow valve, electromagnetic directional valve electromagnet DT simba remukana, reversing valve left basa, maviri-nzira hydraulic mota iri kutenderera, tyaira hopper mublender kune yechipiri kusanganisa hopper mukongiri, uye iyo kongiri cylinder yekudyisa, kana musanganisi blade iri aggregate yakanamirwa mukati mehopper, Kana kudzvanywa kuri muhurongwa kuchikwira kune yakaseti yekumanikidza relay relay, iyo yekumanikidza relay inobuda.
Kusanganisa wedunhu sisitimu yepombi yekongiri inowanzoshandiswa pari zvino, sisitimu inoumbwa nepombi yekubatsira (giya pombi), superposition yekuyamura vharafu, pressure relay, electromagnetic reversing valve uye maviri-nzira hydraulic mota.
Kusanganisa oiri yakakwira kudzvinyirirwa kunodzorwa ne stack overflow valve, electromagnetic directional valve electromagnet DT simba remukana, reversing valve left basa, maviri-nzira hydraulic mota iri kutenderera, tyaira hopper mublender kune yechipiri kusanganisa hopper mukongiri, uye iyo kongiri silinda yekudya, kana musanganisi blade iri aggregate yakanamirwa mukati mehopper, Kana kudzvanywa kuri muhurongwa kukakwira kune yakagadzika kudzvanywa kweiyo pressure relay, iyo yekumanikidza relay inotumira chiratidzo kupa simba iyo electromagnet DT, iyo inodzosera valve inoshanda pa. chinzvimbo chakakodzera, uye iyo hydraulic mota inotyaira iyo agitator kudzosera kumashure kutenderera, kuitira kuti aggregate yakanamatira muagitator inodonha.
Kana iyo agitator ichidzosera kumashure kwakati wandei, magineti emagetsi anodzima otomatiki, vharafu inodzokera kumashure inodzokera kuruboshwe, uye iyo hydraulic mota inotyaira agitator kuti itendeuke.
Maitiro Ebasa:
l) Iyo huru yemafuta edunhu system ine inogara ichiita simba basa. Iyo pombi huru inopa kumanikidza mafuta kudunhu guru remafuta uye dunhu remafuta revhavha yekugovera. Basa repombi yekubatsira nderekugadzirisa otomatiki shanduko yepombi huru kuti ive nechokwadi chekuti pombi huru iri musimba rinogara riripo. Kana dzvinyiriro ichidzikira nekuchinja kwemutoro, kutamiswa kwepombi huru kunowedzera uye simba rekubuda repombi huru rinochengetwa risingaperi, iro rinogona kushandisa zvizere simba remota, kuvandudza kushanda zvakanaka uye kudzivirira mota kubva. overload.
2) pane maviri mahombe hydraulic cylinder akamisa vharafu yekuvimba, vharafu ine mabasa matatu: kana hydraulic cylinder piston parwendo, kupera kwemafuta pamusoro pebuffer one-way throttle valve kuvhura muromo, kuita chikamu chepamusoro. mafuta ekumanikidza nemafuta e-buffer mune yakaderera yekumanikidza mhango, dzikisa iyo gasi yekumanikidza musiyano, iyo piston velocity inoderedzwa, ita chinangwa cheiyo buffer, uye kugadzirira iyo piston commutation; Inogona kushandiswa kuzadza gango remafuta kuti ive nechokwadi chekurova kwepiston kunoshanda. Oiri yechiratidzo kuburikidza nekutonga kwechiteshi chemafuta kuita kuti hydraulic shanduko yevhavha ipedze iyo inotevera kupomba chiito chepombi yekongiri.
3) Batanidza dunhu remafuta revhavha yekugovera kune huru oiri redunhu system. Parizvino, iyo yemumba hydraulic system yekongiri pombi inowanzo shongedzerwa neakanakisa oiri redunhu system yevhavha yekugovera. Kuti uve nechokwadi chekuchinja kwakasimba uye nekukurumidza kwevhavha yekugovera, iyo accumulator inofanira kuiswa muhurongwa.
Mukugadzirwa kweiyo hydraulic system, kuburikidza ne hydraulic reversing valve uye electromagnetic reversing valve inogovera mafuta evharuvhu uye huru oiri system. Hydraulic reversing valve uye electromagnetic reversing valve ndiwo mavharuvhu anosanganisa. Iwo anodzorwa nemafuta ekumanikidza kubva kune inozvimiririra hydraulic cylinder, kuitira kuti kudzvanywa kweoiri kubuda kubva papombi huru kunopinda mumasilinda maviri ekugovera mavharuvhu zvichichinja, nekuona kudzoreredzwa kwevhavha yekuparadzira, uye kusangana nezvinodiwa zvepombi yekongiri yekukurumidza. uye kudzoreredza kwakasimba kwevhavha yekuparadzira.
Maitiro ekuita nekutadza kwe hydraulic system yekongiri pombi rori? Kukanganisa kwakajairika uye nzira dzekurapa dze hydraulic system yekongiri pombi rori:
1. Hapana kumanikidzwa kana kushayikwa kwekumanikidzwa muhurongwa
Dambudziko: Ivhavha yekuyamura yakazaruka, nokuti spool yakanamatira, haigoni kuvharwa, gomba rinoputika rakavharwa, spool uye chigaro hachifananidzi zvakanaka kana chitubu chinopera.
Kugadzirisa: Gadzirisa spool uye goko, chenesa gomba rekunyorovesa, tsiva chitubu.
Dambudziko: Iyo spool yemamwe mavharuvhu ekudzora inonamira nekuda kwekutadza, zvichikonzera kuburitsa.
Kugadzirisa: Tsvaga chikamu chekukanganisa, kuchenesa kana kugadzirisa, ita spool mubvudzi rinoshanduka kufamba.
Dambudziko: Hydraulic components inopfeka zvakakomba, kana chisimbiso kukuvadzwa, zvichikonzera kubuda kwemukati nekunze.
Solution: Tarisa kuvharwa kwepombi, valve uye pombi yekubatanidza, kugadzirisa kana kutsiva zvikamu uye chisimbiso.
2. Kuyerera kusina kukwana
Matambudziko: Iyo tangi nhanho yakaderera, iyo viscosity yemafuta yakakura, uye kuvharika kwesefa kunoita kuti mafuta ako apinzwe.
Solution: Tarisa chiyero chemvura, zadza oiri, tsiva iyo hydraulic mafuta neakakodzera viscosity, uye simbisa dhayamita yepombi yekudhonza.
Dambudziko: hydraulic pombi idling kupfeka zvakakomba, kuita kuderera.
Solution: Tarisa injini, hydraulic pombi uye hydraulic pombi inoshanduka mashandiro, kana zvichidikanwa, shandura pombi.
Dambudziko: Pombi yekudzoka iri pamusoro pemvura, uye mhepo inopinda.
Solution: Tarisa kana pombi yekubatanidza uye chisimbiso chakarurama uye chakavimbika.
Dambudziko: accumulator mhepo kuvuza, kudzvanywa uye kuyerera kwekupa hakuna kukwana.
Solution: Tarisa accumulator kuita uye kumanikidza.
3, kubuda
Dambudziko: Chibatanidzwa chakasununguka uye chisimbiso chakakuvadzwa.
Mhinduro: Simbisa chinongedzo uye wotsiva chisimbiso.
Dambudziko: kubatanidza kweplate kana flange yekubatanidza pamusoro pechiso sikuruu pretightening simba haina kukwana kana kuvhara chisimbiso.
Solution: The pre-tightening force yakakura kudarika fluid pressure, tsiva chisimbiso.
Dambudziko: The system pressure yakareba kupfuura yakayerwa kushanda kudzvanywa kwe hydraulic components kana ebetsero zvikamu.
Solution: element shell pressure haifanire kunge yakakura kudarika inobvumidzwa mafuta seal pressure, shandura chisimbiso.
4, kunyanya kupisa
Dambudziko: Kugadziriswa kusina kunaka kwekumanikidza, kushanda kwenguva refu pasi pekumanikidzwa kwakanyanya.
Kugadzirisa: Gadzirisa kudzvinyirira kwevhavha yekuyamura kune yakakosha kukosha, uye uvandudze dunhu kana zvichidikanwa.
Dambudziko: Kurasikirwa kwesimba rakawandisa nekuda kwekudonhedza uye kukwesha kwemagetsi muhurongwa.
Solution: Tarisa kuvuza, vandudza chisimbiso, gadzirisa iko iko kwekugadzira kwezvikamu zvinofamba, kurongeka kwegungano uye mamiriro ekuzora.
5, vibration
Matambudziko: hydraulic pombi, inhalation yemhepo, yekumisikidza yakakwira zvakanyanya, mafuta absorption kuramba, giya zino chimiro kurongeka hakuna kukwana, blade yakanamatira uye yakatyoka, plunger yakanamatira uye nhare haichinjike, zvikamu zvinopfeka zvinoita kuti kubvumidzwa kwakakura kwazvo.
Mhinduro: Tsiva chisimbiso cheinopinza mafuta, dhigirii kubva pachiteshi chekuyamwa mafuta kusvika pachiteshi chepombi chekuyamwa mafuta chinofanira kunge chiri pasi pe500mm, ive nechokwadi chekuti dhayamita repombi yekukwevera, kugadzirisa kana kutsiva zvikamu zvakakanganisika.
Matambudziko: Iyo hydraulic oiri, iyo yemvura nhanho yakadzikira, kudzika pombi yekuisa kudzika hakuna kukwana, iyo viscosity yemafuta yakakura kwazvo, sefa yakavharwa.
Kugadzirisa: Wedzera mafuta, kurebesa pombi yekukweva uye kunyura kune yakadzama yakataurwa, tsiva viscosity hydraulic mafuta, uye chenesa sefa.
Matambudziko: vharafu yekufashukira, gomba rakavharika, kupenya kwakanyanya pakati pepakati pevharuvhu uye chigaro chevharuvhu, kutadza kwechirimo.
Solution: Geza gomba rekunyorovesa, gadzirisa mukaha pakati pepakati pevharuvhu nechigaro, uye tsiva chitubu.
Dambudziko: Imwe spool haifambi zvakanaka.
Solution: Geza uye deburr.
Matambudziko: Mapaipi, mapaipi akatetepa, hapana chakagadziriswa mudziyo, kudhumhana, pombi yekukweva uye pombi yekudzosera iri padhuze.
Solution: Iyo yakagadziriswa mudziyo wakaiswa kuti uwedzere kureba pakati pemapaipi uye chinhambwe pakati pekusveta pombi uye pombi yekudzoka.
