Iziko leMveliso

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 yokubuyisela ingaphantsi kwe-0.05MPa) ukuqinisekisa ukwenziwa kakuhle ukuhamba kunye nokucoca ubomi. Ke sikhetha njani isihluzo seoyile yehydraulic ngokuchanekileyo? Umhleli ukuxelela ukuba kufuneka uthathele ingqalelo le miba mi-5 ilandelayo:

1. Ukuchaneka kokuhlunga

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)

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 se-hydraulic oil filter element lixabiso le-β eligqitywe ngokwe-ISO4572-1981E (uvavanyo lwe-multi-pass test), oko kukuthi, i-oyile exutywe nomgubo wovavanyo oluqhelekileyo ijikeleziswa ngesihluzo seoyile amaxesha amaninzi. , kunye ne-oyile yokungena kunye ne-oyile kumacala omabini esihluzo seoli. 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

Isihluzo seoli 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.

Isihluzo se-oyile yeHydraulic ligama lobuchwephesha kwishishini lokuhluza. Ukuze kuhlanjululwe imithombo yendalo yokuqala kunye nokusetyenziswa kwakhona kwezibonelelo, izixhobo zokucoca ziyafuneka. Ngoku into yokucoca isetyenziswa ikakhulu kukucoca ioyile, ukuhluzwa komoya, ukuhluzwa kwamanzi kunye namanye amashishini okucoca. Imathiriyeli ye-hydraulic oil filter element ibandakanya isihluzo sephepha, isihluzo sekhemikhali (ifayibha yeglasi, ifayibha yentsimbi, ifayibha ye-polypropylene, ifayibha yepolyester) i-mesh filter element (i-mesh yentsimbi estainless) kunye ne-line gap filter element. I-hydraulic oil filter element ifanele ukuhluza i-asidi eyomeleleyo, i-alkali eyomeleleyo kunye ne-organic solvent. I-membrane yokucoca sisihluzo sobunzulu obugotyiweyo, esinendawo enkulu yokucoca, umahluko ophantsi woxinzelelo, ubumdaka obunamandla obubambekayo kunye nobomi benkonzo ende. Kukho iimodeli ezahlukeneyo kunye neenkcukacha zokukhetha kuzo.
