Isikhungo Somkhiqizo

I-elementi yokuhlunga uwoyela we-hydraulic imakwe kusampula lomkhiqizo womkhiqizi noma i-nameplate ngokunemba kokuhlunga, hhayi ukunemba okuphelele kokuhlunga. Inani elingu-β kuphela elilinganiswa ngokuhlolwa elingamela umthamo wokuhlunga wesihlungi. 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 sikawoyela obuyayo ungaphansi kuka-0.05MPa) ukuqinisekisa ukwenziwa kahle impilo yesici sokugeleza nesihlungi. Ngakho-ke sikhetha kanjani isihlungi samafutha we-hydraulic ngendlela efanele? I-Dalan hydraulic editor ikutshela ukuthi udinga ukucabangela izici ezinhlanu ezilandelayo.

1. Ukunemba kokuhlunga kwesici sokuhlunga uwoyela we-hydraulic

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)

Isihlungi sikawoyela weHydraulic

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 lezakhi zokuhlunga uwoyela we-hydraulic yinani elingu-β elinqunywa ngokuya nge-ISO4572-1981E (ukuhlolwa kwama-multi-pass), okungukuthi, uwoyela oxutshwe nempushana yokuhlola ejwayelekile isakazwa ngesihlungi samafutha izikhathi eziningi. , kanye ne-oyili ne-outlet kuzinhlangothi zombili zesihlungi sikawoyela. 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

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.
