Iziko leendaba

Ngaphambi kokukhetha into yokucoca, kufuneka siqale sicacise ukungaqondi kakuhle okubini:

(1) Ukukhetha into yokucoca ngokuchaneka okuthile (Xμm) kunokucoca onke amasuntswana amakhulu kunolu chanekileyo.

Okwangoku, ixabiso le-β liqhele ukusetyenziswa kumazwe ngamazwe ukumela impumelelo yohluzo lwelungu lokucoca. Into ebizwa ngokuba yi-β ixabiso libhekiselele kumlinganiselo wenani lamasuntswana amakhulu kunobungakanani obuthile kulwelo kwindawo yokungena yesihluzo ukuya kwinani lamasuntswana amakhulu kunomlinganiselo othile kulwelo kwindawo yokukhupha into yokucoca. . Ngoko ke, ixabiso elikhulu le-β, liphezulu ukusebenza kakuhle kohluzo lwesici sokucoca.

Inokubonwa ukuba nayiphi na into yokucoca lulawulo oluchanekileyo, hayi ulawulo oluchanekileyo. Ngokomzekelo, ukuchaneka kokucoca kwe-PALL Corporation e-United States ilinganiswe xa ixabiso le-β lilingana no-200. Xa ukhetha into yokucoca, ngaphezu kokuchaneka kokucoca kunye nokusebenza kakuhle kokucoca, inkqubo yezinto eziphathekayo kunye nesakhiwo sesici sokucoca kufuneka kwakhona. kuqwalaselwa, kwaye iimveliso ezinoxinzelelo oluphezulu lokuwa, i-fluidity ephezulu kunye nobomi benkonzo ende kufuneka ikhethwe.

(2) Umyinge wokuqukuqela olinganisiweyo (oqhelekileyo) wesihluzo sesona santya sokuhamba kwenkqubo.

Kwiminyaka yakutshanje, idatha yokhetho enikezelwe ngabavelisi basekhaya besihluzi abafane bakhankanye ubudlelwane phakathi komyinge wokuhamba okureyithiweyo kwento yokucoca kunye nenqanaba lokuqukuqela lokwenyani lenkqubo, ebangela ukuba umyili wenkqubo abe nenkohliso yokuba umyinge wokuqukuqela olinganisiweyo. yesihluzo sesona santya sokuqukuqela senkqubo yolwelo lwamanzi. Ngokolwazi olufanelekileyo, ukuhamba okulinganiselweyo kwe-filter element yizinga lokuhamba kweoli edlulayo kwindawo yokucoca ecocekileyo phantsi kokumelana okuchaziweyo kokuqala xa i-oil viscosity i-32mm2 / s. Nangona kunjalo, kwizicelo ezisebenzayo, ngenxa yeendaba ezahlukeneyo ezisetyenzisiweyo kunye nobushushu benkqubo, i-viscosity yeoli iya kutshintsha nangaliphi na ixesha. Ukuba i-elementi yokucoca ikhethwe ngokokuhamba okuhleliweyo kunye nesantya sokuhamba kwe-1: 1, xa i-viscosity ye-oyile yenkqubo inkulu kancinane, ukuchasana kweoli edlulayo kwi-filter element kuyanda (umzekelo, i-viscosity ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-oyile ye-1: 1). No. 32 ioli ye-hydraulic kwi-0 ° C malunga ne-420mm2 / s) , Nokuba ifikelele kwixabiso le-filter element ye-pollution blockage, i-filter element ithathwa njengento evaliweyo. Okwesibini, into yokucoca into yokucoca yinxalenye enxityiweyo, ethi ingcoliseke ngokuthe ngcembe ngexesha lomsebenzi, eyona ndawo isebenzayo yokucoca yesixhobo sokucoca iyancitshiswa ngokuqhubekayo, kwaye ukuchasana kweoyile edlula kwinto yokucoca ifikelela ngokukhawuleza. ixabiso lomqondiso we-blocker yongcoliseko. Ngale ndlela, into yokucoca kufuneka icocwe okanye itshintshwe rhoqo, nto leyo eyandisa iindleko zokusetyenziswa komsebenzisi. Kwakhona kuya kubangela ukwehla kwexesha elingeyomfuneko okanye nokuyeka imveliso ngenxa yabasebenzi abalahlekisayo bolondolozo.

Okukhona kuphezulu ukuchaneka kohluzo lwesihluzi se-hydraulic, kungcono?

Isiphumo sokuhluza esichanekileyo silungile, kodwa oku kukungaqondi kakuhle. Ukuchaneka kwe-hydraulic oil filter element efunwa yi-hydraulic system ayikho "phezulu" kodwa "ifanelekile". Izinto zokucoca ioyile yehydraulic echaneke kakhulu zinamandla okudlula ioyile (kwaye ukuchaneka kwezinto zokucoca ioyile yolwelo oyile efakwe kwindawo ezahlukeneyo ayinakufana), kunye nezinto ezichanekileyo zokucoca ioyile yehydraulic nazo zinokuvaleka. Enye yeyobomi obufutshane kwaye kufuneka itshintshwe rhoqo.

Amanyathelo okukhetha i-oyile ye-Hydraulic

Ukhetho ngokubanzi lunala manyathelo alandelayo:

①Fumana awona malungu anovakalelo kungcoliseko kwinkqubo, kwaye umisele ucoceko olufunwa yinkqubo;

②Qinisekisa indawo yofakelo, ifom yokucoca kunye nenqanaba lokuhamba koxinzelelo lwento yokucoca;

③Ngokomahluko omiselweyo woxinzelelo kunye nenqanaba lokuqukuqela, bhekisa kwi-β ixabiso legophe lezinto ezahlukeneyo zokucoca, kwaye ukhethe imathiriyeli yesihluzo kunye nobude. Fumana ukuhla koxinzelelo lweqokobhe kunye noxinzelelo lwecebo lokucoca ukuhla kwisampulu yetshathi, kwaye emva koko ubale umahluko woxinzelelo, oyile: △ isiqalelo secebo lokucoca ulwelo≤△p icebo lokucoca; △p assembly≤△p useto lwendibano. Umenzi ngamnye wecebo lokucoca e-China ubalule umyinge wokuqukuqela okalisiweyo wesici sokucoca esiveliswe ngabo. Ngokwamava adlulileyo kunye nokusetyenziswa kwabathengi abaninzi, xa ioli esetyenziswe kwinkqubo ioli ye-hydraulic jikelele, kucetyiswa ukuba into yokucoca ikhethwe ngokuphindaphindiweyo kwezi zihlandlo zokuhamba. :

a Ukuhamba okulinganiselweyo kokufunxa i-oyile kunye nezihluzo zokubuyiswa kwe-oyile kungaphezulu kwamaxesha ama-3 okuhamba kweyona nkqubo;

b Umqukuqelo olinganisiweyo wesici sokucoca umbhobho ungaphezulu kwamaxesha ama-2.5 okona kuhamba kwenkqubo. Ukongeza, izinto ezinjengendawo yokusebenza, ubomi benkonzo, ukuphindaphindwa kwecandelo, kunye nemidiya yokukhetha inkqubo kufuneka iqwalaselwe ngokufanelekileyo ukufezekisa injongo yokhetho lokucoca.

Izilumkiso zofakelo lwe-oyile ye-hydraulic filter element

Indawo yokufakela kufuneka ithathelwe ingqalelo, nayo iyinxalenye ebaluleke kakhulu. Ukuba awuqinisekanga ukuba ungayifaka phi, awukwazi ukukhetha into yokucoca ioli yehydraulic. Umsebenzi kunye nokuchaneka kwezinto zokucoca ioli ye-hydraulic kwiindawo ezahlukeneyo nazo zihluke.
