Isici sokuhlunga uwoyela we-hydraulic kufanele futhi sihlangabezane nezidingo zokulahleka kwengcindezi (umehluko ophelele wengcindezi yesihlungi somfutho ophezulu ungaphansi kuka-0.1PMa, futhi umehluko ophelele wengcindezi yesihlungi sokubuyisela uwoyela ungaphansi kuka-0.05MPa) ukuqinisekisa ukwenziwa kahle impilo yesici sokugeleza nesihlungi. Ngakho-ke sikhetha kanjani isihlungi samafutha we-hydraulic ngendlela efanele? Umhleli ukutshela ukuthi udinga ukucabangela izici ezi-5 ezilandelayo:
1. Ukunemba kokuhlunga
Okokuqala, thola izinga lokuhlanzeka kwamabala ngokuya ngezidingo zesistimu ye-hydraulic, bese ukhetha ukunemba kwesihlungi sesihlungi samafutha ngokwezinga lokuhlanzeka ngokusho kwetafula lophawu. Into evame ukusetshenziswa kakhulu yesihlungi sikawoyela we-hydraulic emishinini yokwakha inedigri yokuhlunga engu-10μm. Ukuhlanzeka kukawoyela weHydraulic (ISO4406) Ukunemba kokuhlunga okuncane kwesici sokuhlunga (μm) Ibanga lohlelo 13/103 I-valve ye-Hydraulic servo (enesici sokuhlunga esingu-3μm) 16/135 Ivalvu elinganayo ye-hydraulic (enesici sokuhlunga esingu-5μm) 18/1510 Izingxenye ezijwayelekile zamanzi angu-100MP ) (enesici sokuhlunga esingu-10μm) 19/1620 izingxenye ezijwayelekile ze-hydraulic (<10MPa) (enesici sokuhlunga esingu-20μm)
Njengoba ukunemba kokuhlunga kwegama akukwazi ukukhombisa ngokweqiniso umthamo wokuhlunga wesici sokuhlunga, ububanzi bezinhlayiya eziyindilinga enkulu kunazo zonke isihlungi esingadlula ngaphansi kwezimo zokuhlola ezishiwo ngokuvamile sisetshenziswa njengokunemba okuphelele kokuhlunga ukuze kubonise ngokuqondile ukuhlunga kokuqala kwesihlungi. isici sokuhlunga esisanda kufakwa. Umbandela obaluleke kakhulu wokuhlola ikhono lesici sokuhlunga uwoyela we-hydraulic yinani elingu-β elinqunywa ngokuya nge-ISO4572-1981E (ukuhlolwa kwamaphasi amaningi), okungukuthi, uwoyela oxutshwe nempushana yokuhlola ejwayelekile isakazwa ngesihlungi samafutha izikhathi eziningi. , kanye nendawo yokukhipha uwoyela nendawo yokukhipha uwoyela kuzinhlangothi zombili zesisefo samafutha. isilinganiso senani lezinhlayiya.
2. Izici zokugeleza
Ukugeleza nokwehla kokucindezela kwesici sokuhlunga esidlula uwoyela kuyimingcele ebalulekile yezimpawu zokugeleza. Ukuhlolwa kwesici sokugeleza kufanele kwenziwe ngokwezinga le-ISO3968-91 ukuze kudwetshwe ijika lesici se-flow-pressure drop. Ngaphansi kwengcindezi yokunikezwa kukawoyela elinganiselwe, ukwehla kwengcindezi ephelele (inani lokwehla kokucindezela kwendlu yesihlungi nokwehla kokucindezela kwesici sokuhlunga) ngokuvamile kufanele kube ngaphansi kuka-0.2MPa. Ukugeleza okukhulu: 400lt/min Ukuhlolwa kwe-viscosity kawoyela: 60to20Cst Ukugeleza okuncane I-turbine: 0℃ 60lt/min Ukugeleza okuphezulu I-Turbine: 0℃ 400lt/min
3. Amandla esihlungi
Ukuhlolwa komthelela wokuqhekeka kuzokwenziwa ngokuhambisana ne-ISO 2941-83. Umehluko wengcindezi owehla kakhulu lapho isici sokuhlunga sonakaliswa kufanele sibe mkhulu kunenani elishiwo.
4. Izici zokukhathala ezigelezayo
Kufanele ihambisane nokuhlolwa kokukhathala okujwayelekile kwe-ISO3724-90. Izinto zokuhlunga kufanele zihlolwe ukukhathala emijikelezweni engu-100,000.
5. Ukuhlolwa kokuguquguquka kwamafutha we-hydraulic
Isihlungi sikawoyela weHydraulic
Ukuhlolwa kokumelana nokugeleza kwengcindezi kufanele kwenziwe ngokwezinga le-ISO2943-83 ukuze kuqinisekiswe ukuhambisana kwezinto zokuhlunga namafutha we-hydraulic.
Isilinganiso sokuhlunga isilinganiso sika-b sibhekisela esilinganisweni senani lezinhlayiyana ezinkulu kunosayizi onikeziwe oketshezini ngaphambi kokuhlunga enanini lezinhlayiya ezinkulu kunosayizi onikeziwe oketshezini ngemva kokuhlunga. Nb=inombolo yezinhlayiya ngaphambi kokuhlunga Na=inombolo yezinhlayiyana ngemva kokuhlunga X=usayizi wezinhlayiyana.
Isici sokuhlunga uwoyela weHydraulic yitemu lochwepheshe embonini yokuhlunga. Ukuze kuhlanzwe izinsiza zokuqala zemvelo kanye nokusetshenziswa kabusha kwezinsiza, okokusebenza kokuhlanza kuyadingeka. Manje isici sokuhlunga sisetshenziswa kakhulu ekuhlungeni uwoyela, ukuhlunga komoya, ukuhlunga amanzi nezinye izimboni zokuhlunga. Impahla yesihlungi sikawoyela we-hydraulic ikakhulukazi ifaka isihlungi sephepha, i-chemical fiber filter element (i-glass fibre, i-metal fibre sintered feel, i-polypropylene fibre, i-polyester fibre) i-mesh filter element (i-stainless steel mesh) kanye nesici sokuhlunga igebe lomugqa. Isici sokuhlunga uwoyela we-hydraulic sifanele ukuhlunga i-asidi eqinile, i-alkali eqinile kanye ne-organic solvent. I-membrane yesihlungi isihlungi sokujula esigoqiwe, esinendawo enkulu yokuhlunga, umehluko ophansi wengcindezi, umthamo oqinile wokubamba ukungcola kanye nempilo ende yesevisi. Kunamamodeli ahlukahlukene kanye nokucaciswa ongakhetha kukho.
