I-Loudm-Shram-Ikholeji ye-Hydraulic cinezela i-oyile ye-hydraulic kwibhloko yevalve phantsi kwento yempompo yeoyile. Inkqubo yolawulo ilawula ivalve nganye ukuze i-hydraulic ye-hydraulic ifikelela kumagumbi aphezulu kunye nasezantsi kwe-hydraulic cylicter, eshukumisa i-hydraulic mercoulic to racine. Umatshini wokushicilela we-hydraulic sisixhobo esisebenzisa ulwelo ukuba lidlulise uxinzelelo.
I-Hydraulic oyile ibaluleke kakhulu kwiikholamu ezinekholamu ezine zeKholam kwaye yenye yamanyathelo abalulekileyo ukunciphisa unxibe umatshini. Ukukhetha ioyile echanekileyo ye-hydraulic inxulumene ngqo nobomi benkonzo bomatshini we-hydraulic.
Xa ukhetha ioyile yeKholamu yeHuloulic Hydraulic, kufuneka uqale ukhethe i-viscofity efanelekileyo. Ukukhethwa kweoyile kufuneka kuthathe ingqalelo iimpawu zesakhiwo, ubushushu bokusebenza kunye noxinzelelo lokusebenza kwenkqubo ye-hydraulic. Kwinkqubo yokuhambisa i-hydraulic, impompo yeoyile yenye yezona zinto zibuthathaka kakhulu zokutshintsha kwi-Hydralic Viscoulity. Iindidi ezahlukeneyo zempompo nganye zinobuncinci kwaye zininzi ezivunyiweyo. Ukwenzela ukunciphisa ukusetyenziswa kwamandla, ioyile ene-viscofity ephantsi kufuneka isetyenziswe ngokubanzi kangangoko kunokwenzeka. Nangona kunjalo, ukwenzela ukuthambisa izinto eziphambili kwaye kuthintele ukuvuza, ioyile ye-hydraulic ye-viscofity efanelekileyo kufuneka ikhethwe.

I-1. I-Hydraulic Model Discution
Iimodeli ze-Hydraulic ze-Hydraulic zihlelwa kwiindidi ezintathu zoMgangatho: uhlobo lwe-HL, uhlobo lwe-HL, kunye nohlobo lwe-HG.
. Ngokwentshukumo kwi-40 degrees Celsius, i-viscofity inokwahlulwa ngokwamabakala amathandathu: 32, 46, 68, ne-100.
. Ngokwentshukumo yama-40 eCelsius, i-viscosity yahlulahlulwe yangamabanga amane: 22, 326, kunye ne-68.
(3) Uhlobo lwe-HG lune-anti-rust kunye neepropathi ze-oxidation. Ngapha koko, i-Viscosity yesalathiso songezwa, esinophawu oluhle-uphawu lobushushu.
I-2. Imodeli ye-Hydraulic Seage
. IiMveliso ngokubanzi zineenguqulelo ezilungileyo kakhulu, kwaye amaqondo obushushu aphezulu anokufikelela kwi-80 degrees Celsius.
. Ukongeza, olu hlobo lweoyile ye-hydraulic lukwalungele uxinzelelo oluphakathi kunye nezixhobo zobunjineli boxinzelelo oluphezulu kunye neenkqubo ze-hydraulic.
.
Amaqondo obushushu osebenza nge-heles ye-hydraulic oils yamabakala ahlukeneyo okufana phantsi kweemfuno ezahlukeneyo azi ngolu hlobo lulandelayo.

Zininzi iindidi zeoyile ye-hydraulic kwintengiso, kwaye zininzi iindidi zoomatshini be-hydraulic. Nangona imisebenzi yeoyile ye-hydraulic ifana, kusafuneka ukukhetha ioyile eyahlukileyo ye-hydraulic yoomatshini obahlukileyo we-hydraulic. Xa ukhetha ioyile ye-hydraulic, abasebenzi kufuneka baqonde ukuba yintoni ecelwe ukuba yenze, emva koko ukhethe ioyile ye-hydraulic ye-hydraulic umatshini we-hydraulic.
Ungayikhetha njani ioyile ye-hydraulic ye-hydraulic cinezela
Iindlela ezimbini zihlala zisetyenziswa xa ukhetha ioyile ye-hydraulic. Inye kukukhetha ioyile ye-hydraulic ngokweentlobo zeoyile kunye neenkcazo ezicetyiswa yi-hydraulic cocapes zomenzi okanye imiyalelo. Enye into kukujonga ukuqonda kweoyile ye-hydraulic ngokusekwe kwiimeko ezithile zoomatshini bokusebenza, ezinjengoxinzelelo lokusebenza, amaqondo obushushu asebenzayo, isantya sentshukumo, uhlobo lwezinto ze-hydraulic kunye nezinye izinto.
Xa ukhetha, eyona misebenzi iphambili ekufuneka yenziwe yile: Ukumisela uluhlu lwe-viscofity yeoyile ye-hydraulic, khetha iintlobo ezifanelekileyo zeoli, kwaye hlangabezana neemfuno zenkqubo ye-hydraulic system.
Ihlala ikhethiwe ngokwale miba ilandelayo:
(1) Ngokhetho olwahlukileyo lwe-hydraulic conitations yoomatshini bokusebenza
Oomatshini bokuchasana noomatshini abaqhelekileyo banezinto ezahlukeneyo zokufakwa kwi-viscofity. Ukwenzela ukunqanda ukungcungcuthekiswa kwamacandelo omatshini obangelwe kukunyuka kobushushu kwaye kuchaphazele ioyile yokuchaneka, oomatshini bokuchazela kufuneka basebenzise ioyile ye-hydraulic ene-viscosity esezantsi.
(2) Khetha ngokohlobo lwempompo ye-hydraulic
Impompo ye-hydraulic yinto ebalulekileyo ye-hydraulic mer. Kumatshini wokushicilela we-hydraulic, isantya sayo sokuhamba, ingcinezelo kunye noxinzelelo lweqondo liphakame, kwaye ixesha layo lokusebenza lide, ke iimfuno zokubonisa i-vicovity zihambahamba. Ke impompo ye-hydraulic kufuneka ithathelwe ingqalelo xa ukhetha i-viscofity.
(3) Khetha ngokobugcisa bokusebenza kwe-hydraulic cinezela
Xa uxinzelelo luphezulu, ioyile ene-viscofity ephezulu kufuneka isetyenziselwe ukunqanda ukuvuza ngenkqubo yokuvuza kunye nokusebenza kakuhle. Xa uxinzelelo lokusebenza luphantsi, kungcono ukusebenzisa ioyile ngohlobo oluphantsi, olunokuphucula ukulahleka koxinzelelo.
(4) Qwalasela ubushushu bokusebenza kwindalo esingqongileyo ye-hydraulic
I-viscosity yeoyile yeoyile itshintsha kakhulu ngenxa yempembelelo yobushushu. Ukuqinisekisa ukubonwa okufanelekileyo kubushushu bokusebenza, impembelelo yeqondo elingaphakathi elijikelezileyo kufuneka lithathelwe ingqalelo.
(5) Cinga ngesantya sokuhamba samanqaku okusebenza kwe-hydraulic mer
Xa isantya esishiyiweyo samacandelo okusebenza kwinkqubo ye-hydraulic ephezulu kakhulu, ilahleko yokuhamba kweoyile ikhula ngokungacwangciswanga, kwaye kungcono ukusebenzisa ioyile.
(6) Khetha uhlobo olufanelekileyo lweoyile ye-hydraulic
Ukukhetha ioli ye-hydraulic evela kubavelisi abaqhelekileyo kunokunciphisaUmatshini woshicilelo lwe-hydraulicUkusilela kwaye kwandise ubomi boomatshini beendaba.
