ICinezela kwiKholam yeHuloulicihambisa ioli ye-hydraulic kwibloko yevalve phantsi kwesenzo sempompo yeoli.Inkqubo yokulawula ilawula i-valve nganye ukwenzela ukuba i-oyile ye-hydraulic ephezulu ifikelele kumagumbi aphezulu kunye nangaphantsi kwe-cylinder ye-hydraulic cylinder, ebangela ukuba i-hydraulic press ihambe.I-Hydraulic press sisixhobo esisebenzisa ulwelo ukuhambisa uxinzelelo.
Ioli ye-hydraulic ibaluleke kakhulu kwiikholamu ezine ze-hydraulic press kwaye yenye yemilinganiselo ebalulekileyo yokunciphisa ukunxiba koomatshini.Ukukhetha i-oyile ye-hydraulic echanekileyo ihambelana ngqo nobomi benkonzo yomatshini we-hydraulic.
Xa ukhetha ioli ye-column-column hydraulic press, kufuneka uqale ukhethe i-viscosity efanelekileyo.Ukukhethwa kwe-oil viscosity kufuneka kuthathelwe ingqalelo iimpawu zesakhiwo, ukushisa okusebenzayo kunye noxinzelelo olusebenzayo lwenkqubo ye-hydraulic.Kwinkqubo yokuhanjiswa kwe-hydraulic, impompo yeoli yenye yezona zinto zibuthathaka kakhulu kwiinguqu kwi-viscosity yeoli ye-hydraulic.Iindidi ezahlukeneyo zeempompo nganye ine-viscosity encinci kunye nephezulu evumelekileyo.Ukunciphisa ukusetyenziswa kwamandla, ioli ene-viscosity ephantsi kufuneka isetyenziswe ngokubanzi kangangoko kunokwenzeka.Nangona kunjalo, ukwenzela ukugcoba amacandelo abalulekileyo kunye nokuthintela ukuvuza, ioli ye-hydraulic ye-viscosity efanelekileyo kufuneka ikhethwe.

1. UHlelo lweModeli yeOyile yeHydraulic
Iimodeli zeoyile yeHydraulic zihlelwa ngokwemigangatho emithathu yesizwe: uhlobo lweHL, uhlobo lweHM, kunye nohlobo lweHG.
(1) I-HL yodidi lweoli ye-hydraulic yenziwe kwi-oyile yesiseko esulungekisiweyo, ephakathi, kunye ne-antioxidant kunye ne-anti-rust.Ngokutsho kwentshukumo kwi-40 degrees Celsius, i-viscosity inokwahlulwa ibe ngamabakala amathandathu: 15, 22, 32, 46, 68, kunye ne-100.
(2) Iintlobo ze-HM ziquka i-alkaline ephezulu, i-alkaline ephantsi ye-zinc, i-zinc ephezulu engathathi hlangothi kunye neentlobo ezingenamlotha.Ngokutsho kwentshukumo kwi-40 degrees Celsius, i-viscosity ihlukaniswe ngamabakala amane: 22, 32, 46, kunye ne-68.
(3) Uhlobo lwe-HG lune-anti-rust kunye ne-anti-oxidation properties.Ngaphezu koko, i-index ye-viscosity index yongezwa, eneempawu ezintle ze-viscosity-temperature.
2. Ukusetyenziswa kweModeli yeOli yeHydraulic
(1) I-HL ioli ye-hydraulic isetyenziselwa ukuthambisa kwiibhokisi zokuthwala kunye neenkqubo zokujikeleza okuphantsi koxinzelelo lwezixhobo ezahlukeneyo zoomatshini apho kungekho mfuneko zikhethekileyo zeoli kunye nobushushu be-ambient bungaphezu kwe-zero degrees Celsius.Iimveliso ezinjalo ngokubanzi zinokuguquguquka okuhle kakhulu kokutywinwa, kwaye ubushushu obuphezulu bokusebenza bunokufikelela kuma-80 degrees Celsius.
(2) I-oyile ye-HM ye-hydraulic isetyenziswa kakhulu kwiinkqubo ze-hydraulic ze-heavy-duty, i-medium-pressure kunye ne-high-pressure vane impompo, iimpompo ze-plunger kunye neempompo zegiya.Ukongeza, olu hlobo lweoyile ye-hydraulic ifanelekile kuxinzelelo oluphakathi kunye noxinzelelo oluphezulu lwezixhobo zobunjineli kunye neenkqubo ze-hydraulic zemoto.
(3) I-HG ioli ye-hydraulic ine-anti-rust efanelekileyo, i-anti-oxidation, i-anti-wear, kunye ne-anti-stick-slip-slip properties, ngoko ke ifaneleka kakhulu kwiinkqubo zokuthambisa ezisebenzisa i-hydraulics yesixhobo somatshini kunye nemizila yesikhokelo.
Ukushisa okusebenzayo kweeoli ze-hydraulic zamabanga ahlukeneyo e-viscosity phantsi kweemfuno ezahlukeneyo zimi ngolu hlobo lulandelayo.
| Ibakala leViscosity (40℃) iisentistoke | I-viscosity efunekayo ekuqaliseni i-860 centistokes | I-viscosity efunekayo ekuqaliseni i-110 centistokes | I-viscosity ephezulu efunekayo ngexesha lokusebenza yi-54 centistokes | I-viscosity ephezulu efunekayo ngexesha lokusebenza yi-13 centistokes |
| 32 | -12℃ | 6℃ | 27℃ | 62℃ |
| 46 | -6℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
Kukho iintlobo ezininzi zeoyile yolwelo loxinzelelo olukhulu emarikeni, kwaye kukho neentlobo ezininzi zoomatshini bokwenza amanzi.Nangona imisebenzi yeoyile ye-hydraulic ifana ngokusisiseko, kuseyimfuneko ukukhetha ioyile yehydraulic eyahlukeneyo koomatshini abahlukeneyo behydraulic.Xa ukhetha ioyile yehydraulic, abasebenzi kufuneka bayiqonde eyona nto icelwa ukuba bayenze, kwaye emva koko bakhethe ioyile yehydraulic echanekileyo yomatshini woxinzelelo.
Ungayikhetha njani ioyile ye-hydraulic ye-hydraulic cinezela
Zimbini iindlela ezisoloko zisetyenziswa xa kukhethwa ioyile yehydraulic.Enye kukukhetha i-oyile esebenza ngoxinzelelo lwe-hydraulic ngokweentlobo ze-oyile kunye neenkcukacha ezicetyiswayo ziisampuli okanye imiyalelo yomenzi we-hydraulic press.Enye kukuqwalasela ngokubanzi ukukhethwa kweoli ye-hydraulic ngokusekelwe kwiimeko ezithile zomatshini we-hydraulic, njengoxinzelelo lokusebenza, ukushisa okusebenzayo, isantya sokunyakaza, uhlobo lwamacandelo e-hydraulic kunye nezinye izinto.
Xa ukhetha, imisebenzi ephambili ekufuneka yenziwe yile: ukugqiba uluhlu lwe-viscosity yeoli ye-hydraulic, ukukhetha iindidi zeoli ye-hydraulic efanelekileyo, kunye nokuhlangabezana neemfuno ezikhethekileyo zenkqubo ye-hydraulic.
Idla ngokukhethwa ngokwale miba ilandelayo:
(1) Ngokokhetho olwahlukeneyo loomatshini bokushicilela behydraulic
Oomatshini bokuchaneka kunye noomatshini ngokubanzi banemfuno ezahlukeneyo ze-viscosity.Ukuze ugweme ukuguqulwa kwamalungu omatshini okubangelwa ukunyuka kweqondo lokushisa kunye nokuchaphazela ukuchaneka kokusebenza, oomatshini abachanekileyo kufuneka basebenzise ioli ye-hydraulic kunye ne-viscosity ephantsi.
(2) Khetha ngokohlobo lwempompo ye-hydraulic
Ipompo ye-hydraulic yinxalenye ebalulekileyo ye-hydraulic press.Kwi-press hydraulic press, isantya sokunyakaza kwayo, uxinzelelo kunye nokunyuka kweqondo lokushisa kuphezulu, kwaye ixesha layo lokusebenza lide, ngoko ke iimfuno ze-viscosity zinzima.Ngoko impompo ye-hydraulic kufuneka ithathelwe ingqalelo xa ukhetha i-viscosity.
(3) Khetha ngokoxinzelelo olusebenzayo lwe-hydraulic press
Xa uxinzelelo luphezulu, i-oyile ene-viscosity ephezulu kufuneka isetyenziswe ukuphepha ukuvuza okugqithisileyo kwenkqubo kunye nokusebenza okuphantsi.Xa uxinzelelo lokusebenza luphantsi, kungcono ukusebenzisa ioyile ngohlobo oluphantsi, olunokuphucula ukulahleka koxinzelelo.
(4) Qwalasela iqondo lobushushu lendawo yokusebenza yoshicilelo olwenziwa ngamanzi aphantsi komhlaba
I-viscosity yeoli yamaminerali itshintsha kakhulu ngenxa yefuthe lobushushu.Ukuze kuqinisekiswe i-viscosity efanelekileyo ngakumbi kwiqondo lokushisa lokusebenza, impembelelo yeqondo lokushisa elijikelezayo kufuneka liqwalaselwe.
(5) Qwalasela isantya sokuhamba seendawo ezisebenzayo ze-hydraulic press
Xa isantya esihambayo samacandelo asebenzayo kwinkqubo ye-hydraulic iphezulu kakhulu, izinga lokuhamba kweoli liphantsi, ilahleko ye-hydraulic iyanda ngokungaqhelekanga, kwaye ukuvuza kuyancipha, ngoko ke kungcono ukusebenzisa ioli nge-viscosity ephantsi.
(6) Khetha uhlobo olufanelekileyo lweoli eqhutywa ngamanzi
Ukukhetha ioli ye-hydraulic evela kubakhiqizi abaqhelekileyo kunokunciphisaumatshini wokushicilela owenziwe ngehydraulicukusilela kunye nokwandisa ubomi bomatshini wokushicilela.
