Rabshadda afarta-sadar ee saxaafadda saxaafadda waxay u horseedisaa saliida hydralic saliida weelka waalka hoostiisa ee ku xusan ficilka bamka saliida. Nidaamka xakamaynta ayaa xakameynaya warar kasta si saliidda cadaadiska sare ay u gaarto qolalka sare iyo kuwa hoose ee dhulululeedka hydralic ee dhulululeedka, taasoo ku kalifay in ay u dhaqaaqdo saxaafadda. Saxaafadda hydralic saxaafadda waa aalad u adeegsada dareeraha si loo gudbiyo cadaadis.
Saliidda hydraulic saliida ayaa aad muhiim ugu ah cadaadiska ku jira afarta sadarka ah oo waa mid ka mid ah tillaabooyinka muhiimka ah ee lagu yareynayo xirashada mashiinka. Xulashada saliida saliida saxda ah waxay si toos ah ula xiriirtaa nolosha adeegga ee mashiinka hydralic.
Markaad dooranayso saliida saxaafadda afarta sadarka ah, waa inaad marka hore doorataa Viscosity ku habboon. Xulashada codsiga saliida waa inay tixgelisaa astaamaha qaab dhismeedka, heerkulka shaqeeya iyo cadaadiska shaqada ee nidaamka hydralic. Nidaamka gudbinta hydralic, bamka saliidu waa mid ka mid ah qaybaha ugu nugul ee isbeddelada ku dhaca viscosity saliid ah. Noocyo kala duwan oo bambooyin ah mid walbaa wuxuu leeyahay ugu yaraan uguna sarreeya viscosity. Si loo yareeyo isticmaalka korantada, saliida leh viscosity hoose guud ahaan waa in loo istcimaalaa inta ugu badan ee suuragalka ah. Si kastaba ha noqotee, si loo saliido qaybaha muhiimka ah iyo ka hortagga baxsiga, saliida hydraulic ee viscosity ku habboon ayaa u baahan in la doorto.

1. Noocyada Qaabka Saliida ee Hydralic
Moodooyinka saliida ee hydraulic waxaa lagu kala saaraa seddex qaybood oo heer qaran ah: Nooca HL, nooca HM, iyo nooca HG.
(1) Saliidda hldralic ee nooca leh waxaa laga sameeyay saliid qotodheer oo qoto dheer, oo ay weheliso antioxidant iyo miridhku ka hortaga. Marka loo eego dhaqdhaqaaqa 40 darajo Celsius, viscosity-ka waxaa loo qaybin karaa lix fasal: 15, 22, 32, 46, 68, iyo 100.
(2) Noocyada HM waxaa ku jira alkaline-ka sare, alkaline hooseeya, zinc-ka sare ee zinc iyo nooc aan lahayn. Marka loo eego dhaqdhaqaaqa 40 digrii Celsius, viscosity-ka waxaa loo qaybiyaa afar fasal: 22, 32, 46, iyo 68.
(3) Nooca Hg wuxuu leeyahay anti-miridhku iyo anti-offilis. Intaa waxaa dheer, in muuqaalka muujinta viscosity-ka ayaa lagu daray, kaas oo leh astaamo heerkul ah oo heerkul ah.
2. Adeegsiga Moodeelka Saliida ee Hydralic
(1) Saliida hydralic saliida waxaa loo isticmaalaa saliidaha lagu hayo sanaadiiqda sanaadiiqda iyo nidaamyada wareegga dhiigga ee yar ee aaladaha mashiinka ah ee aan lahayn shuruudo gaar ah oo loogu talagalay saliida iyo heerkulka deegaanka ayaa ka sareeya eber heerarka Celsius. Alaabada noocan oo kale ah guud ahaan waxay leeyihiin la-qabsi aad u wanaagsan oo aad u wanaagsan, oo heerkulka ugu badan ee hawlgalka ayaa gaari kara 80 digrii Celsius.
(2) Hm saliida hydraulic waxaa badanaa loo isticmaalaa nidaamyada hydraulic ee khasabka culus, cadaadiska dhexdhexaadka ah iyo bambooyin vane-ka-sareeya, bambooyin tuubooyin ah iyo matoorrada. Intaas waxaa sii dheer, noocan ah saliidda noocan ah ee saliida leh ayaa sidoo kale ku habboon cadaadis dhexdhexaadin ah iyo qalabka injineerinta cadaadiska sare iyo nidaamyada hydraulic.
(3) Hg Hindralic saliida leh miridhku, anti-xinjiida, anti-xiridda, anti-stick-still-sticks, sidaa darteed waxay inta badan ku habboon tahay nidaamyada lineration ee isticmaalaya mashiinka mashiinka mashiinka hagaha.
Heerkulka hawlgalka ee saliidaha hydraulic ee fasalada viscosity-ka ee ku saleysan shuruudaha kaladuwan waa sida soo socota.
| Fasalka viscosity (40 ℃) centricokes | Muuqaalka loo baahan yahay ee bilowga bilowga waa 860 centricottes | Muuqaalka loo baahan yahay ee bilowga bilowga waa 110 centiristates | MAAMULKA MUQDISHO EE MUQDISHO MARKA AAD U BAAHAN YAHAY | MAAMULKA FARSAMADA EE MUQDISHO MARKA AAD KA MID AH ISTICMAALKA |
| 32 | -12 ℃ | 6 ℃ | 27 ℃ | 62 ℃ |
| 46 | -6 ℃ | 12 ℃ | 34 ℃ | 71 ℃ |
| 68 | 0 ℃ | 19 ℃ | 42 ℃ | 81 ℃ |
Waxaa jira noocyo badan oo saliid ah oo saliid ah oo ku yaal suuqa, waxaana sidoo kale jira noocyo badan oo mashiinnada hydralic ah. In kasta oo howsha saliida saliida asal ahaan la mid ah, weli waa lama huraan in la doorto saliidaha dareeraha kaladuwan ee mashiinnada kaladuwan ee hydralic. Markaad dooranayso saliida hydralic, shaqaaluhu waa inay fahmaan waxa inta badan lagu weydiisto in la sameeyo, ka dibna dooro saliida saxda ah ee saliida saxda ah ee mashiinka hydralic.
Sida loo doorto saliida saxda ah ee saliida ee saxaafadda hydralic saxaafadda
Laba hablood ayaa badanaa loo isticmaalaa marka la xusho saliida hydralic. Mid waa in la xusho saliida hydralic sida ku xusan noocyada saliida iyo faahfaahinta ay ku talinayaan saxaarada soo saara ee saxaafada ama tilmaamaha. Midda kale waa in si dhammaystiran looga fiirsado xulashada saliida hydralic ee ku saleysan xaaladaha gaarka ah ee mashiinka hydralic, sida cadaadiska shaqada, sida heerkulka shaqada, xawaaraha dhaqdhaqaaqa, nooca qaybaha dareeraha ah iyo qodobo kale.
Markaad dooranayso, howlaha ugu weyn ee la qabanayo waa: go'aaminta aragtida muuqaalka ee saliida hydralic saliida, xulashada noocyada ugu habboon ee saliida ku habboon ee saliida, iyo la kulanka baahiyaha gaarka ah ee nidaamka hydralic.
Badanaa loo xushay dhinacyada soo socda:
(1) Sida laga soo xigtay xulashooyinka kala duwan ee saxaafadda biyaha ee ku shaqeeya
Mashiinada saxda ah iyo mashiinnada guud waxay leeyihiin shuruudo muuqaal ah oo kaladuwan. Si looga fogaado inuu ka fogaado qaybo ka mid ah qaybo ka mid ah heerkulka kor u kaca oo saameyn ku yeelata saxnaanta shaqada, mashiinada saxda ah waa inuu u adeegsadaa saliida hydralic ee viscosity hoose.
(2) Xulo si waafaqsan nooca bamka hydraulic
BATCRAULIC CUSUB waa qayb muhiim ah oo ka mid ah saxaafadda hydralic saxaafadda. Saxaafadda ku jirta ee xawaaraha, xawaaraha dhaqdhaqaaqa, cadaadiska iyo heerkulka kor u kaca ayaa sarreeya, waqtigeeda shaqaduna waa dheer tahay, sidaa darteed shuruudaha puscosity waa mid adag. Marka bamka hydraulic waa in la tixgeliyaa marka la doorto viscosity.
(3) Xulo si waafaqsan cadaadiska shaqada ee saxaafadda hydralic saxaafadda
Marka cadaadiska uu sarreeyo, saliida leh viscosity-ka sare waa in loo istcimaalaa si looga fogaado daadashada nidaamka xad dhaafka ah iyo hufnaanta hoose. Marka cadaadiska shaqadu hooseeyo, waxaa fiican in loo isticmaalo saliida leh viscosity hoose, kaasoo yareyn kara cadaadiska.
(4) Tixgeli heerkulka jawiga shaqada ee saxaafadda hydralic saxaafadda
Muuqaalka sawirka saliida macdanta wax badan ayaa wax ka badala waxyaabo ay sabab u tahay saamaynta heerkulka. Si loo hubiyo in laga fiirsado ku habboon oo ku habboon heerkulka shaqada, saameynta heerkulka deegaanka ku xeeran waa in sidoo kale la tixgeliyaa.
(5) Tixgeli xawaaraha dhaqdhaqaaqa ee qaybaha shaqada ee saxaafadda hydralic
Marka xawaaraha dhaqdhaqaaqa ee ka socda nidaamka ku shaqeeya ee nidaamka hydralic uu aad u sarreeya, heerka qulqulka saliida sidoo kale waa mid hooseysa, luminta dareeraha ah ayaa si aan kala sooc lahayn u sii kordhayaa, sidaa darteedna waxaa fiican in la isticmaalo saliida viscosity hoose.
(6) Dooro nooca ku habboon ee saliida hydralic
Doorashada saliida hydralic ee soosaarayaasha caadiga ah ayaa yareyn karaMashiinka Saxaafadda HydralicGuul darrooyinka iyo dheereeya nolosha mashiinka saxaafadda.
