Theafar sariirood oo sariiraha haydarooliga ahwuxuu keenaa saliid biyo-biyood ah block-ka valve ee hoos yimaada waxqabadka bamka saliidda.Nidaamka xakamaynta ayaa xakameynaya waal kasta si saliidda cadaadiska sare ay u gaarto qolalka sare iyo hoose ee dhululubada haydarooliga, taas oo keeneysa in sariirta haydarooliga ay dhaqaaqdo.Saxaafadda Hydraulic waa aalad adeegsata dareeraha si ay cadaadiska u gudbiso.
Saliidda Haydarooliga ayaa aad muhiim ugu ah madbacadaha haydarooliga ee afar-saxan waana mid ka mid ah tallaabooyinka muhiimka ah ee lagu dhimayo xirashada mashiinka.Doorashada saliidda saxda ah ee saxda ah waxay si toos ah ula xiriirtaa nolosha adeegga mashiinka hydraulic.
Markaad dooranayso saliidda afar-tiir hydraulic press, waa inaad marka hore doorataa viscosity habboon.Xulashada viscosity saliidda waa inay tixgelisaa sifooyinka qaabdhismeedka, heerkulka shaqada iyo cadaadiska shaqada ee nidaamka hydraulic.Nidaamka gudbinta hydraulic, bamka saliidda waa mid ka mid ah qaybaha ugu xasaasisan ee isbeddelka ku yimaada viscosity saliidda.Noocyada kala duwan ee bambooyin mid kastaa wuxuu leeyahay ugu yaraan iyo ugu badnaan viscosity la oggol yahay.Si loo yareeyo isticmaalka tamarta, saliidda maqaarkoodu hooseeyo waa in guud ahaan loo isticmaalo inta ugu badan ee suurtogalka ah.Si kastaba ha noqotee, si loo saliido qaybaha muhiimka ah loogana hortago daadinta, saliidda hadhka ee viscosity habboon ayaa loo baahan yahay in la doorto.

1. Kala-saarista Qaabka Saliidda Haydarooliga
Moodooyinka saliidda haydarooliga waxaa loo kala saaray saddex qaybood oo heer qaran ah: nooca HL, nooca HM, iyo nooca HG.
(1) Nooca HL ee Saliida Haydarooliga waxaa laga sameeyay saliid la safeeyey, oo qoto dheer oo qoto dheer oo saliid saldhig ah, oo lagu daray antioxidant iyo anti- miridhku daro.Marka loo eego dhaqdhaqaaqa 40 darajo Celsius, viscosity waxaa loo qaybin karaa lix fasal: 15, 22, 32, 46, 68, iyo 100.
(2) Noocyada HM waxaa ka mid ah alkaline-ka sarreeya, zinc-ka hooseeya ee alkaline, zinc-ka dhexdhexaad ah iyo noocyada ash-la'aanta.Marka loo eego dhaqdhaqaaqa 40 darajo Celsius, viscosity wuxuu u qaybsan yahay afar fasal: 22, 32, 46, iyo 68.
(3) Nooca HG wuxuu leeyahay sifooyin liddi ku ah miridhku.Waxaa intaa dheer, hagaajinta index viscosity ayaa lagu daray, kaas oo leh sifooyin heerkul-kulul oo wanaagsan.
2. Isticmaalka Model Saliida Haydarooliga
(1) Saliida hydraulic ee HL waxaa loo isticmaalaa in lagu sifeeyo sanduuqyada xanbaarsan iyo hababka wareegga cadaadiska hooseeya ee qalabka mashiinka kala duwan halkaasoo aysan jirin shuruudo gaar ah oo saliid ah iyo heerkulka jawigu wuxuu ka sarreeyaa eber Celsius.Badeecadaha noocan oo kale ah guud ahaan waxay leeyihiin la qabsi daboolid aad u wanaagsan, iyo heerkulka ugu sarreeya ee hawlgalka wuxuu gaari karaa 80 darajo Celsius.
(2) Saliida Haydarooliga ee HM waxaa inta badan lagu isticmaalaa nidaamyada hawo-biyoodka ee culeyska culus, cadaadiska dhexdhexaadka ah iyo matoorada vane-ga-cadaadiska ah, bambooyinka tuubooyinka iyo matoorada gear.Intaa waxaa dheer, noocan oo kale ah saliid hydraulic waxay sidoo kale ku habboon tahay cadaadiska dhexdhexaadka ah iyo qalabka injineernimada cadaadiska sare iyo hababka gawaarida.
(3) Saliida Haydarooliga ee HG waxay leedahay ka hortag wanaagsan oo miridhku, ka-hortagga oksaydhka, ka-hortagga xidhka, iyo guryaha-ku-shubasho, sidaa darteed waxay inta badan ku habboon tahay nidaamyada sifaynta ee isticmaala qalabka mashiinka mashiinka iyo biraha hagaha.
Heerkulka shaqada ee saliidaha hydraulic ee darajooyinka viscosity ee kala duwan ee shuruudaha kala duwan waa sida soo socota.
| Viscosity fasalka (40 ℃) sentistokes | Viscosity loo baahan yahay bilowga hore waa 860 sentistokes | Viscosity loo baahan yahay bilowga hore waa 110 sentistokes | viscosity ugu badan ee loo baahan yahay inta lagu jiro hawlgalka waa 54 sentistokes | viscosity ugu badan ee loo baahan yahay inta lagu jiro hawlgalka waa 13 sentistokes |
| 32 | -12℃ | 6℃ | 27℃ | 62℃ |
| 46 | -6℃ | 12℃ | 34℃ | 71℃ |
| 68 | 0℃ | 19℃ | 42℃ | 81℃ |
Waxaa jira noocyo badan oo saliid biyo-biyood ah oo suuqa ku jira, sidoo kale waxaa jira noocyo badan oo mashiinnada biyaha ah.Inkasta oo hawlaha saliidda hydraulic ay asal ahaan isku mid yihiin, weli waa lagama maarmaan in la doorto saliidaha kala duwan ee mashiinnada hydraulic ee kala duwan.Marka la dooranayo saliidda biyaha, shaqaaluhu waa inay fahmaan waxa inta badan la weydiiyo inay sameeyaan, ka dibna dooro saliidda saxda ah ee mashiinka hawo-qaadista.
Sida loo doorto Saliida Haydarooliga saxda ah ee Madbacada Haydarooliga
Laba hab ayaa badanaa la isticmaalaa marka la dooranayo saliidda biyaha.Mid waa in la doortaa saliidda biyo-mareenada iyadoo loo eegayo noocyada saliidda iyo qeexida ay ku taliyaan sambabada ama tilmaamaha saaraha saxafada haydarooliga.Midda kale waa in si buuxda loo tixgeliyo xulashada saliidda hydraulic ee ku salaysan shuruudaha gaarka ah ee mashiinka hydraulic, sida cadaadiska shaqada, heerkulka shaqada, xawaaraha dhaqdhaqaaqa, nooca qaybaha hydraulic iyo arrimo kale.
Markaad dooranayso, hawlaha ugu muhiimsan ee la qabanayo waa: go'aaminta qiyaasta viscosity ee saliidda hydraulic, xulashada noocyada saliidda ee ku habboon, iyo buuxinta baahiyaha gaarka ah ee nidaamka hydraulic.
Caadi ahaan waxaa lagu soo xulaa dhinacyada soo socda:
(1) Marka loo eego xulashooyinka kala duwan ee mashiinnada ku shaqeeya saxaafadda haydarooliga
Mashiinada saxda ah iyo mashiinada guud waxay leeyihiin shuruudo viscosity kala duwan.Si looga fogaado qallafsanaanta qaybaha mishiinada ee ay keento kor u kaca heerkulka oo ay saamayso saxnaanta shaqada, mashiinada saxda ah waa in ay isticmaalaan saliida hadhka leh ee viscosity hoose.
(2) Dooro iyadoo loo eegayo nooca bamka hydraulic-ga
Bamka hydraulic waa qayb muhiim ah oo ka mid ah saxaafadda hydraulic.Saxafada hydraulic-ka, xawaaraha dhaqdhaqaaqa, cadaadiska iyo kor u kaca heerkulka ayaa sarreeya, wakhtigeeda shaqadu waa dheer yahay, markaa shuruudaha viscosity waa adag yihiin.Markaa bamka hydraulic waa in la tixgeliyaa marka la dooranayo viscosity.
(3) Dooro iyadoo loo eegayo cadaadiska shaqada ee saxaafadda hydraulic
Marka cadaadisku sarreeyo, saliid leh viscosity sare waa in la isticmaalaa si looga fogaado daadinta nidaamka xad-dhaafka ah iyo waxtarka hooseeya.Marka cadaadiska shaqadu hooseeyo, waxaa fiican in la isticmaalo saliid leh viscosity hoose, taas oo yareyn karta luminta cadaadiska.
(4) Tixgeli heerkulka deegaanka shaqada ee saxaafadda hydraulic
Viscosity ee saliidda macdanta isbedel badan sababtoo ah saamaynta heerkulka.Si loo hubiyo viscosity ku habboon heerkulka shaqada, saamaynta heerkulka agagaarka ku hareeraysan waa in sidoo kale la tixgeliyaa.
(5) Tixgeli xawaaraha dhaq-dhaqaaqa qaybaha shaqada ee madbacadaha haydarooliga
Marka xawaaraha dhaqdhaqaaqa ee qaybaha shaqada ee nidaamka hydraulic uu aad u sarreeyo, heerka qulqulka saliidda ayaa sidoo kale hooseeya, khasaaraha hydraulic ayaa kordha si aan kala sooc lahayn, qulqulka ayaa yara yaraaday, sidaas darteed waxaa fiican in la isticmaalo saliid leh viscosity hoose.
(6) Dooro nooca habboon ee saliidda biyaha
Doorashada saliidda hydraulic ee soo saarayaasha caadiga ah waxay yarayn kartaamashiinka saxaafadda ee hydraulicguuldarrooyinka iyo kordhinta nolosha mashiinka saxaafadda.
