Madhan jet waalka DN1500
Hollow Jet Valve
Waalka jet-ka bannaan waa nooc ka mid ah waalka loo isticmaalo nidaamyada xakamaynta dareeraha. Waalkan waxa loo qaabeeyey iyada oo dhexda dalool ama dalool, taas oo u oggolaanaysa in dareeruhu ka gudbo.
Waalka jet-ka bannaan waa nooc ka mid ah waalka loo isticmaalo nidaamyada xakamaynta dareeraha. Waalkan waxa loo qaabeeyey iyada oo dhexda dalool ama dalool, taas oo u oggolaanaysa in dareeruhu ka gudbo. Waxaa caadi ahaan loo isticmaalaa codsiyada halka xawaaraha sare iyo xakamaynta jihada ee dareeraha ay muhiim u yihiin. Daloolka jet-ka ee bannaan wuxuu caadi ahaan ka kooban yahay jir leh meel laga soo galo iyo meel laga soo baxo, iyo saxan dhaqaaqi karo ama saxan xakameynaya qulqulka dareeraha. Marka waalka uu ku jiro booska xiran, Orifice wuxuu xannibaa socodka dareeraha. Sida waalka loo furo iyada oo ka fogaynaysa kursiga, dareeruhu wuxuu sii mari karaa xarunta bannaan wuxuuna ka soo bixi karaa meesha laga baxo.
Mashiinnada jet-ka ee bannaan ayaa inta badan loo adeegsadaa biyo-xireenka biyaha, iyo koronto-abuurista. Waxay si gaar ah faa'iido ugu leeyihiin xakamaynta qulqulka dareeraha cadaadiska sarreeya ama xawaaraha sarreeya, halkaasoo kontoroolka saxda ah iyo hawlgal hufan ay lagama maarmaan tahay. Naqshadaynta iyo agabka loo isticmaalo jet valves-ka bannaan way kala duwanaan karaan iyadoo ku xiran codsiga gaarka ah iyo nooca dareeraha la xakameynayo. Waxyaabaha ay ka midka yihiin cadaadiska, heerkulka, iyo iswaafajinta kiimikada ayaa loo baahan yahay in la tixgeliyo marka la dooranayo valve jet-ka bannaan ee nidaam gaar ah. Dayactirka joogtada ah iyo kormeerka ayaa muhiim u ah si loo hubiyo in ay si sax ah u shaqeeyaan alwaaxyadan loogana hortago wax kasta oo daadanaya ama fashilma.
Mashiinnadayada godan-jet-ka waxay caddeeyeen waxtarkooda sare ee dhirta korontada laga dhaliyo iyo biyo-xireennada waraabka. Waxay xaqiijiyaan meel-ka-socod biyo ah oo habaysan oo deegaan ahaan ku habboon ha ahaato bannaanka ama taangiyada biyaha hoostooda. Biyaha sidoo kale waxaa lagu hodmay ogsijiin isku mar. Dhismaha tayada sare leh ee birta ah ee jeexjeexyada jet-ka-godan oo ay weheliso xidhid laastikada / birta ah waxay awood u siinaysaa tamarta tamarta iyada oo aan la daboolin.
- Tilmaamaha Nakhshad-
Codsiga biyo-xireenka, valves-ka-kontoroolka sida jet-ka-madhan ayaa lagu rakibaa ka dib fallaadhaha balanbaalista ee dhinaca dibadda. Shabagyadani waxay had iyo jeer u shaqeeyaan sidii habaynta socodka ama valves control. Hallow jet valves loogu talagalay inay qabtaan nidaaminta ama xakamaynta.
◆Ka shaqaynta nidaamka bixinta biyaha iyada oo aan wax gariir ahi ka dhicin inta la furayo waalka.
- Faa'iidooyinka -
◆Isbeddel sax ah
◆Cavitation ma jiro
◆Gariir la'aan
◆Ku shaqaynta gacanta waxay u baahan tahay xoog yar. Iyada oo aan loo eegin xaaladda piston, xoogga loo baahan yahay si loo dhaqaajiyo piston-ka ee si fiican u furan oo xiran waa isku mid.
◆Sababta oo ah ku shubidda hawada ma jirto sabab rabshado ah oo looma baahna in lagu rakibo dubbe-biyoodka ka hortagga xagga hoose.
◆ Dayactirka fudud
