Restriktorius T28BB s15 turbai.

Post by Raizo »

Zodziu situacija tokia. Uzkuriau savo caske su T28bb turba. Ziuriu melynai dumina, paskui nuemus IC slanga, pasirodo pilna tepalo. Iskart galvoju, kad ragas turbinai. Bet pasidomejus, sako kad sitoms turboms reikalingas restriktorius.
hmm, o as sito nezinojau :oops: Gal zinote kokio diamiatro jis reikalingas?
Cia iskarpa is straipsniuko vieno (In addition, lower oil flow further reduces the risk of oil leakage compared to journal-bearing turbochargers)

jeigu rašo .035 - tai coliai, kas yra 0.889mm.
jankiai dažniausiai naudoja .03 ball bearing ir .06 journal bearing turbakams. kas lietuviams yra 0,8-1mm guolinėms ir ~1,5mm paprastiems įvoriniams turbams.

dekui uz atsakymus, einu valyti IC, bandysiu deti i banjo varzta, nuo kempo varini antgaliuka 1mm, gausis kaip restriktorius. :)


O cia radau, kazkoki straipsniuka apie turbas:

Does my turbo require an oil restrictor?

Oil requirements depend on the turbo's bearing system type. Garrett has two types of bearing systems; traditional journal bearing; and ball bearing.

The journal bearing system in a turbo functions very similarly to the rod or crank bearings in an engine. These bearings require enough oil pressure to keep the components separated by a hydrodynamic film. If the oil pressure is too low, the metal components will come in contact causing premature wear and ultimately failure. If the oil pressure is too high, leakage may occur from the turbocharger seals. With that as background, an oil restrictor is generally not needed for a journal-bearing turbocharger except for those applications with oil-pressure-induced seal leakage. Remember to address all other potential causes of leakage first(e.g. inadequate/improper oil drain out of the turbocharger, excessive crankcase pressure, turbocharger past its useful service life, etc) and use a restrictor as a last resort.

Garrett distributors can tell you the recommended range of acceptable oil pressures for your particular turbo. Restrictor size will always depend on how much oil pressure your engine is generating-there is no single restrictor size suited for all engines.

Ball-bearing turbochargers can benefit from the addition of an oil restrictor, as most engines deliver more pressure than a ball bearing turbo requires. The benefit is seen in improved boost response due to less windage of oil in the bearing. In addition, lower oil flow further reduces the risk of oil leakage compared to journal-bearing turbochargers. Oil pressure entering a ball-bearing turbocharger needs to be between 40psi and 45psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil inlet on the turbocharger center section. Again, it is imperative that the restrictor be sized according to the oil pressure characteristics of the engine to which the turbo is attached. Always verfiy that the appropriate oil pressure is reaching the turbo

The use of an oil restrictor can(but not always) help ensure that you have the proper oil flow/pressure entering the turbocharger, as well as extract the maximum.

Na va pasidariau, ele restriktoriu :D Kaip manot, ar bus gerai? Ar tie originalus restriktoriai buna, tarkim 1mm skersmens ir ju tas ilgis tarkim koks 5mm.
Cia ipresavau nuo kempo varinio angaliuko, ta dali kur eina su sriegiu, kaip zinia ji pradzioje eina konusu, ta prasme viduje.
tai pas mane gavosi skylutes skersmuo 1mm, ir ilgis maximum iki 2mm.
Ar cia isvis nesamone suburiau, laukiu atsakymu, kol nebus keletos nuomoniu, tol to varsto nesuksiu :D
