Iziko leMveliso

Isihluzo se-oyile esenziwa ngoxinzelelo lwendalo iphawulwe kwisampulu yemveliso yomenzi okanye kwi-nameplate ngokuchaneka kohluzo lwegama, hayi ukuchaneka kokucoca ngokupheleleyo. Kuphela lixabiso le-β elilinganiswe ngovavanyo elinokumela umthamo wokucoca wesihluzi. Isihluzo se-oyile ye-hydraulic kufuneka kwakhona ihlangabezane neemfuno zokulahleka koxinzelelo (umahluko opheleleyo woxinzelelo lwesihluzi soxinzelelo oluphezulu ungaphantsi kwe-0.1PMa, kwaye umahluko opheleleyo woxinzelelo lwe-oyile yokubuya ungaphantsi kwe-0.05MPa) ukuqinisekisa ukwenziwa kakuhle ukuhamba kunye nokucoca ubomi. Ke sikhetha njani isihluzo seoyile yehydraulic ngokuchanekileyo? Umhleli weDalan hydraulic ukuxelela ukuba kufuneka uqwalasele le miba mihlanu ilandelayo.

1. Ukuchaneka kokucoca kwe-hydraulic oil filter element

Okokuqala, misela inqanaba lokucoceka kwamabala ngokweemfuno zenkqubo ye-hydraulic, uze ukhethe ukuchaneka kokucoca kwe-oyile yokucoca ngokwenqanaba lokucoceka ngokwetafile yesimboli. Esona sihluzo seoyile sisetyenziswa kakhulu kumatshini wokwakha sineqondo lokuhluza le-10μm. Ukucoceka kwe-oyile eHydraulic (ISO4406) Ukuchaneka okuqhelekileyo kokucoca kwesixhobo sokucoca (μm) Uluhlu lwe-aplikeshini 13/103 Ivalve ye-Hydraulic servo (ene element ye-3μm yokucoca) 16/135 Ivalve elungelelanisiweyo yeHydraulic (ene-5μm element yokucoca) 18/1510 I-hydraulic components gabalala ) (nge 10μm isihluzo element) 19/1620 amacandelo hydraulic jikelele (<10MPa) (kunye 20μm isihluzo element)

Isihluzo seoli yeHydraulic

Kuba ukuchaneka kwegama lokuhluza akunako ukubonisa ngenene umthamo wokucoca wesici sokucoca, idiameter yelona suntswana likhulu eliqinileyo elingqukuva elinokuthi isihluzi sidlule phantsi kweemeko zovavanyo ezikhankanyiweyo sihlala sisetyenziswa njengokuchaneka kokucoca ngokupheleleyo ukubonisa ngokuthe ngqo ukuhluzwa kokuqala kohluzo. into entsha yokucoca. Eyona nqobo ibalulekileyo yokuvavanya isakhono sezinto zokucoca ioyile yehydraulic lixabiso le-β eligqitywe ngokwe-ISO4572-1981E (uvavanyo lokupasa okuninzi), oko kukuthi, i-oyile exutywe nomgubo wovavanyo oluqhelekileyo ijikeleziswa ngesihluzo seoyile amaxesha amaninzi. , kunye ne-oyile yokungena kunye ne-outlet kumacala omabini okucoca ioli. umlinganiselo wenani lamasuntswana.

2. Iimpawu zokuhamba

Ukuhamba kunye nokuhla koxinzelelo lwe-filter element edlula kwi-oyile yimilinganiselo ebalulekileyo yeempawu zokuhamba. Uvavanyo lweempawu zokuhamba kufuneka luqhutywe ngokwemigangatho ye-ISO3968-91 ukuzoba ijika leempawu zoxinzelelo lokuhamba. Phantsi koxinzelelo lonikezelo lwe-oyile olulinganisiweyo, ukuhla koxinzelelo lulonke (isimbuku sokuhla koxinzelelo lwendlu yokucoca kunye nokuhla koxinzelelo lwento yokucoca) kufuneka ngokubanzi kube ngaphantsi kwe-0.2MPa. Ukuhamba okuphezulu: 400lt / min Uvavanyo lwe-oyile viscosity: 60to20Cst Ubuncinci bokuhamba I-Turbine: 0℃ 60lt/min Ubuninzi bokuhamba I-Turbine: 0℃ 400lt/min

3. Amandla okucoca

Uvavanyo lwempembelelo yokuqhekeka luya kwenziwa ngokuhambelana ne-ISO 2941-83. Umahluko woxinzelelo owehla kabukhali xa isihluzi sisonakala kufuneka sibe sikhulu kunexabiso elichaziweyo.

4. Iimpawu zokudinwa kokuhamba

Kufuneka ihambelane ne-ISO3724-90 yovavanyo oluqhelekileyo lokukhathala. Izinto zokucoca mazivavanywe ukudinwa kwimijikelo eyi-100,000.

5. Uvavanyo lokuziqhelanisa neoyile yehydraulic

Uvavanyo lokumelana nokuhamba koxinzelelo kufuneka luqhutywe ngokwemigangatho ye-ISO2943-83 ukuqinisekisa ukuhambelana kwezinto zokucoca kunye neoli ye-hydraulic.

Umlinganiselo wokuhluza umlinganiselo we-b ubhekisela kumlinganiselo wenani lamasuntswana amakhulu kunomlinganiselo onikiweyo kulwelo ngaphambi kokuhluzwa kwinani lamasuntswana amakhulu kunomlinganiselo onikiweyo kulwelo emva kokuhluzwa. Nb=inani lamasuntswana phambi kokuhluzwa Na=inani lamasuntswana emva kokuhluzwa X=ubungakanani bamasuntswana.
