Muchina wekudzvanya we hydraulic une makoramu mana unoendesa mafuta e hydraulic kuvharuvhu pasi pekushanda kwepombi yemafuta. Sisitimu yekudzora inodzora vharuvhu yega yega kuitira kuti mafuta e hydraulic ane simba repamusoro asvike mumakamuri epamusoro neapasi e hydraulic cylinder, zvichiita kuti hydraulic press ifambe. Muchina wekudzvanya we hydraulic mudziyo unoshandisa mvura kuendesa kumanikidzwa.
Oiri yehydraulic inokosha zvikuru pakushandisa hydraulic presses ine makoramu mana uye ndeimwe yenzira dzakakosha dzekuderedza kusakara kwemuchina. Kusarudza oiri yehydraulic yakakodzera kunoenderana zvakananga nehupenyu hwekushanda kwemuchina wehydraulic.
Pakusarudza oiri ye hydraulic press ine makoramu mana, unofanira kutanga wasarudza viscosity yakakodzera. Kusarudzwa kwe viscosity yeoiri kunofanirwa kufunga nezvehunhu hwechimiro, tembiricha yekushanda uye kumanikidzwa kwekushanda kwe hydraulic system. Mu hydraulic transmission system, pombi yeoiri ndeimwe yezvinhu zvinonyanya kukanganiswa nekuchinja kwe viscosity yeoiri ye hydraulic. Mhando dzakasiyana dzepombi imwe neimwe ine viscosity shoma uye yepamusoro inobvumidzwa. Kuti kuderedza kushandiswa kwesimba, oiri ine viscosity yakaderera inofanira kushandiswa zvakanyanya sezvinobvira. Zvisinei, kuti ifukidze zvikamu zvakakosha uye kudzivirira kubuda kwemvura, oiri ye hydraulic ye viscosity yakakodzera inofanira kusarudzwa.

1. Kupatsanurwa kweModhi yeMafuta eHydraulic
Mhando dzemafuta ehydraulic dzakakamurwa kuita zvikamu zvitatu zvenyika: mhando yeHL, mhando yeHM, uye mhando yeHG.
(1) Oiri ye HL yemhando ye hydraulic yakagadzirwa kubva mumafuta epakati akacheneswa, akadzika zvakanyanya, pamwe ne antioxidant uye anti-ngura zvinowedzera. Zvichienderana nekufamba kwe40 degrees Celsius, viscosity inogona kukamurwa kuita magiredhi matanhatu: 15, 22, 32, 46, 68, uye 100.
(2) Mhando dzeHM dzinosanganisira dzine alkaline yakawanda, alkaline yakaderera zinc, neutral high zinc uye dzisina ashless. Zvichienderana nekufamba kwe40 degrees Celsius, viscosity yakakamurwa kuita magiredhi mana: 22, 32, 46, uye 68.
(3) HG type ine hunhu hwekudzivirira ngura uye hunodzivirira oxidation. Uyezve, chinhu chinovandudza viscosity index chinowedzerwa, chine hunhu hwakanaka hwe viscosity-tembiricha.
2. Kushandiswa kweModhi yeOiri yeHydraulic
(1) Oiri yeHL hydraulic inoshandiswa pakuzora mafuta mumabhokisi ekutakura zvinhu uye masisitimu ekutenderera kwemhepo ane simba shoma ezvishandiso zvakasiyana-siyana zvemuchina uko pasina zvinodiwa zvakakosha zvemafuta uye tembiricha yemhepo iri pamusoro pe zero degrees Celsius. Zvigadzirwa zvakadaro zvinowanzova nekugona kuchinjika zvakanaka, uye tembiricha yepamusoro yekushanda inogona kusvika 80 degrees Celsius.
(2) Oiri yeHM hydraulic inonyanya kushandiswa muma hydraulic systems ane mapombi ane simba guru, ane pressure yepakati nepamusoro uye ane pressure yepamusoro, ma plunger pumps nema gear pomps. Pamusoro pezvo, rudzi urwu rwe hydraulic oil rwakakodzerawo michina yeinjiniya ine pressure yepakati nepamusoro uye ine pressure yepamusoro uye masisitimu e hydraulic emotokari.
(3) Oiri yeHG hydraulic ine hunhu hwakanaka hwekudzivirira ngura, kudzivirira oxidation, kudzivirira kupera, uye kudzivirira kutsvedza, saka inonyanya kukodzera masisitimu ekuzora anoshandisa machina tool hydraulics uye guide rails.
Kupisa kwekushanda kwemafuta e hydraulic ane ma grade akasiyana e viscosity pasi pezvinodiwa zvakasiyana ndekwekuti zvinotevera.
| Masentimita ekusimba egiredhi rekusimba (40℃) | Viscosity inodiwa pakutanga i860 centistokes | Viscosity inodiwa pakutanga i110 centistokes | Viscosity yakanyanya inodiwa panguva yekushanda i54 centistokes | Viscosity yakanyanya inodiwa panguva yekushanda i13 centistokes |

| 46 | -6℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
Kune mhando dzakawanda dzemafuta ehydraulic dziri pamusika, uye kunewo mhando dzakawanda dzemichina yehydraulic. Kunyangwe mabasa emafuta ehydraulic akafanana, zvichiri kukosha kusarudza mafuta akasiyana ehydraulic emichina yakasiyana yehydraulic. Pakusarudza mafuta ehydraulic, vashandi vanofanira kunzwisisa zvinokumbirwa kuti zviitwe, uye vozosarudza mafuta ehydraulic akakodzera emuchina wehydraulic.
Maitiro Ekusarudza Oiri YeHydraulic Yakakodzera YeHydraulic Press
Nzira mbiri dzinowanzo shandiswa pakusarudza mafuta e hydraulic. Imwe ndeyekusarudza mafuta e hydraulic zvichienderana nerudzi rwemafuta uye zvirevo zvinokurudzirwa nemasampuli kana mirairo yemugadziri we hydraulic press. Imwe ndeyekufunga zvakakwana nezvesarudzo yemafuta e hydraulic zvichienderana nemamiriro chaiwo emuchina we hydraulic, akadai sekumanikidzwa kwekushanda, tembiricha yekushanda, kumhanya kwekufamba, mhando yezvikamu zve hydraulic nezvimwe zvinhu.
Pakusarudza, mabasa makuru anofanirwa kuitwa ndeaya: kuona huwandu hwe viscosity yemafuta e hydraulic, kusarudza mhando yakakodzera yemafuta e hydraulic, uye kusangana nezvinodiwa zvakakosha zve hydraulic system.
Kazhinji inosarudzwa zvichienderana nezvinhu zvinotevera:
(1) Zvichienderana nesarudzo dzakasiyana dzemichina yekushanda ye hydraulic press
Michina yekunyatsoshanda nemazvo nemichina yakajairika ine zvinodiwa zvakasiyana zvekupenya. Kuti zvisakanganise zvikamu zvemuchina nekuda kwekupisa kwakanyanya uye kukanganisa kunyatsoshanda, michina yekunyatsoshanda inofanira kushandisa mafuta ehydraulic ane kupenya kwakaderera.
(2) Sarudza zvichienderana nerudzi rwepombi ye hydraulic
Pombi ye hydraulic chinhu chakakosha che hydraulic press. Mu hydraulic press, kumhanya kwayo kwekufamba, kumanikidzwa uye kukwira kwetembiricha kwakanyanya, uye nguva yayo yekushanda yakareba, saka zvinodiwa kuti ive viscosity yakaoma. Saka hydraulic pombi inofanira kufungwa nezvayo pakusarudza viscosity.
(3) Sarudza zvichienderana nekumanikidzwa kwekushanda kwemuchina we hydraulic press
Kana kumanikidzwa kwacho kwakanyanya, oiri ine kusimba kwakanyanya inofanira kushandiswa kudzivirira kubuda kwemvura zvakanyanya uye kushanda zvakanaka. Kana kumanikidzwa kwacho kuri kushoma, zviri nani kushandisa oiri ine kusimba kwakaderera, izvo zvinogona kuderedza kurasikirwa nekumanikidzwa.
(4) Funga nezvekupisa kwenzvimbo yekushanda yemuchina we hydraulic press
Kusviba kwemafuta emineral kunochinja zvakanyanya nekuda kwesimba rekupisa. Kuti kuve nechokwadi chekuti kusviba kwakakodzera pakupisa kwekushanda, simba rekupisa kwemhepo kwakapoteredza rinofanirawo kufungwa nezvaro.
(5) Funga nezvekumhanya kwekufamba kwezvikamu zvinoshanda zvemuchina we hydraulic press
Kana kumhanya kwezvikamu zvinoshanda mu hydraulic system kwakakwira zvikuru, mwero wekuyerera kwemafuta unova wakadererawo, kurasikirwa kwe hydraulic kunowedzera zvisina kurongeka, uye kubuda kwemvura kunenge kwakaderera, saka zviri nani kushandisa mafuta ane viscosity yakaderera.
(6) Sarudza rudzi rwakakodzera rwemafuta ehydraulic
Kusarudza mafuta ehydraulic kubva kune vagadziri venguva dzose kunogona kuderedzamuchina wekudhinda we hydraulickukundikana uye kuwedzera hupenyu hwemuchina wekudhindisa.
