Xarunta Wararka

Kahor intaanan dooran element filter, waa inaan marka hore cadeynaa laba ismaandhaaf:

(1) Doorashada element filter leh sax gaar ah (Xμm) waxay shaandhayn kartaa dhammaan walxaha ka weyn saxsanaantan.

Waqtigan xaadirka ah, qiimaha β waxaa badanaa loo isticmaalaa si caalami ah si uu u matalo hufnaanta sifaynta walxaha shaandhada. Waxa loogu yeero qiimaha β waxaa loola jeedaa saamiga tirada qaybaha ka weyn cabbirka go'an ee dareeraha gudaha galitaanka element filter ilaa tirada qaybo ka weyn cabbirka go'an ee dareeraha ee ka soo baxa xubinta filter-ka . Sidaa darteed, marka uu weynaado qiimaha β, ayaa sare u kacaya waxtarka sifaynta ee walxaha shaandhada.

Waxaa la arki karaa in shay kasta oo shaandheyntu uu yahay kontorool sax ah oo qaraabo ah, oo aan ahayn kantarool sax ah oo dhammaystiran. Tusaale ahaan, saxnaanta shaandhaynta PALL Corporation ee Maraykanka waxa la qiyaasaa marka qiimaha β la mid yahay 200. Markaad dooranayso element filter, marka lagu daro saxnaanta sifaynta iyo hufnaanta shaandhaynta, walxaha iyo habka qaabdhismeedka shaandhada waa in sidoo kale in la tixgeliyo, iyo alaabooyinka leh cadaadiska sare ee burburay, dareeraha sarreeya iyo nolosha adeegga dheer waa in la doortaa.

(2) Qiyaasta qulqulka (magac ahaan) heerka socodka shayga shaandhada waa heerka socodka dhabta ah ee nidaamka.

Sanadihii la soo dhaafay, xogta xulashada ee ay bixiyaan soosaarayaasha walxaha shaandhada guduhu marar dhif ah ayay sheegaan xiriirka ka dhexeeya heerka qulqulka la qiimeeyay ee unugga shaandhada iyo heerka socodka dhabta ah ee nidaamka, taas oo keenta in naqshadeeyaha nidaamka uu leeyahay dhalanteed ah in heerka qulqulka la cabbiray. ee element filter waa heerka socodka dhabta ah ee nidaamka hydraulic. Marka loo eego macluumaadka la xidhiidha, socodka la qiimeeyay ee cunsurka shaandhada ayaa ah heerka socodka saliidda ee maraaya shayga shaandhada nadiifka ah ee hoos yimaada caabbinta asalka ah ee la cayimay marka viscosity oil uu yahay 32mm2/s. Si kastaba ha ahaatee, codsiyada wax ku oolka ah, sababtoo ah warbaahinta kala duwan ee loo isticmaalo iyo heerkulka nidaamka, viscosity ee saliidda ayaa isbeddeli doona wakhti kasta. Haddii element filter loo doorto iyadoo loo eegayo qulqulka la qiimeeyay iyo heerka socodka dhabta ah ee 1: 1, marka viscosity ee saliidda nidaamku wax yar ka weyn tahay, caabbinta saliidda ee dhexmarta walxaha shaandhada ayaa kordha (tusaale ahaan, viscosity of Nambarka 32 Saliida Haydarooliga ee 0°C waxay ku saabsan tahay 420mm2/s) , Xataa marka la gaadho qiimaha shaandhada wasakhaysan ee walxaha shaandhada, qaybta shaandhada ayaa loo arkaa in la xannibay. Marka labaad, qaybta filter-ka ee walxaha shaandhada waa qayb xiran, kaas oo si tartiib tartiib ah u wasakhaysan inta lagu jiro shaqada, goobta shaandhaynta dhabta ah ee wax ku oolka ah ee walxaha si joogto ah ayaa loo yareeyaa, iyo caabbinta saliidda ee dhexmarta qaybta shaandhada waxay si dhakhso ah u gaartaa qiimaha calaamadda xannibaadaha wasakhowga. Sidan, qaybta shaandhada waxay u baahan tahay in la nadiifiyo ama la beddelo si joogto ah, taas oo kordhisa kharashka isticmaalka isticmaalaha. Waxay sidoo kale sababi doontaa waqti-dhimis aan loo baahnayn ama xitaa waxay joojin doontaa wax soo saarka sababtoo ah shaqaalaha dayactirka ee marin habaabinaya.

Markasta oo ay sareeyso saxnaanta sifaynta walxaha shaandhaynta Haydarooliga, ayaa ka fiican?

Saamaynta sifeynta saxda ah ee saxda ah runtii waa mid wanaagsan, laakiin tani dhab ahaantii waa isfaham la'aan weyn. Saxnaanta shayga shaandhada saliidda hadhida-biyoodka ee looga baahan yahay nidaamka hydraulic ma aha "sare" laakiin "ku habboon". Walxaha shaandhada saliidda ee saxda ah ee saxda ah ayaa leh awood-dhaafsi saliideed oo aad u liidata (iyo saxnaanta walxaha shaandhada saliidda biyaha ee lagu rakibay meelo kala duwan isku mid ma noqon karaan), iyo walxaha shaandhada saliidda haydarooliga ee saxda ah sidoo kale waxay u badan tahay in la xannibo. Mid waa cimriga gaaban waana in si joogto ah loo beddelaa.

Tillaabooyinka xulashada shaandhada saliidda Haydarooliga

Xulashada guud waxay leedahay tillaabooyinka soo socda:

① Soo ogow qaybaha ugu xasaasisan wasakhowga nidaamka, oo go'aami nadaafadda looga baahan yahay nidaamka;

②Go'aami booska rakibaadda, qaabka sifaynta iyo heerka socodka cadaadiska ee walxaha shaandhada;

③Marka loo eego farqiga cadaadiska loo dejiyay iyo heerka socodka, tixraac qalooca qiimaha β ee agabyada kala duwan ee shaandhada, oo dooro walxaha shaandhada iyo dhererka. Soo ogow dhibicda cadaadiska qolofka oo ka shaandhee dhibicda cadaadiska element ka shaxda muunada, ka dibna xisaabi faraqa cadaadiska, kuwaas oo ah: △p element filter≤△p filter element settings; △p kulanka≤△p fadhiga. Mid kasta oo soo saara walxaha shaandhada ee Shiinaha ayaa qeexay heerka socodka la qiimeeyay ee walxaha shaandhada ay soo saareen. Marka loo eego waayo-aragnimadii hore iyo isticmaalka macaamiil badan, marka saliidda loo isticmaalo nidaamka ay tahay saliidda guud ee hydraulic, waxaa lagu talinayaa in walxaha shaandhada lagu doorto iyadoo loo eegayo tirada soo socota ee heerka socodka. :

a Qulqulka la qiimeeyay ee nuugida saliidda iyo filtarrada soo celinta saliidda ayaa ka badan 3 jeer socodka dhabta ah ee nidaamka;

b Qulqulka la qiimeeyay ee walxaha shaandhada dhuumaha ayaa ka badan 2.5 jeer socodka dhabta ah ee nidaamka. Intaa waxaa dheer, arrimaha sida deegaanka shaqada, nolosha adeegga, inta jeer ee beddelka qaybaha, iyo nidaamka xulashada warbaahinta waa in sidoo kale si habboon loo tixgeliyo si loo gaaro ujeedada hagaajinta xulashada walxaha shaandhada.

Ka taxadarida rakibaadda walxaha filter saliidda

Goobta rakibaadda waa in la tixgeliyaa, taas oo sidoo kale ah qayb aad u muhiim ah. Haddii aadan hubin meesha aad ku rakibi karto, ma dooran kartid walxaha filter saliidda. Shaqada iyo saxnaanta walxaha shaandhada saliidda hadhida-biyoodka ee meelo kala duwan ayaa sidoo kale kala duwan.
