Tiksliai nustatant temperatūrą, kurioje kondensuojasi vandens garai, rasos taško matavimas suteikia neįkainojamos informacijos apie suslėgto oro kokybę.
Šiame vadove pasinersime į rasos taško matavimo prietaisų pasaulį ir padėsime išsirinkti puikų įrankį, kuris padės apsaugoti suspausto oro sistemą ir optimizuoti veiklą.
Rasos taško supratimas suslėgto oro sistemose
Kas yra rasos taškas?
Rasos taškas tai temperatūra, kai oras prisotinamas vandens garų ir pradeda kondensuotis į skystą vandenį.
Kalbant apie suslėgto oro sistemas, tai temperatūra, kurioje suslėgto oro vandens garai kondensuojasi į skystą pavidalą.
Rasos taško poveikis suslėgto oro kokybei
Suslėgtame ore esanti drėgmė gali turėti neigiamos įtakos sistemos veikimui, saugai ir efektyvumui. Štai kaip:
- Įrangos pažeidimai: Skystas vanduo gali smarkiai pažeisti pneumatinius įrankius, vožtuvus, cilindrus ir kitus komponentus. Dažnai pasitaiko korozijos, erozijos ir hidraulinio blokavimo problemų.
- Produkto užterštumas: Drėgmė gali užteršti gaminius, ypač tokiose pramonės šakose kaip farmacija, maisto pramonė ir elektronika.
- Sumažėjęs efektyvumas: Vandens garai didina suslėgto oro tūrį, todėl mažėja kompresoriaus efektyvumas ir didėja energijos sąnaudos.
- Sistemos veikimo problemos: Drėgmė gali sukelti pneumatinių sistemų apledėjimą, dėl kurio atsiranda gedimų ir prastovų.
- Saugos pavojai: Tam tikrais atvejais drėgmė gali sukelti pavojingas sąlygas, pavyzdžiui, suvirinant ar dažant purškiamuoju būdu.
Tiksliai matuodami rasos tašką galite nustatyti galimas problemas ir imtis korekcinių veiksmų, kad apsaugotumėte savo įrangą, produktus ir darbuotojus.
