Erken Ba\u015far\u0131s\u0131zl\u0131\u011f\u0131n 5 Temel Nedeni<\/h2>\n\n\n\n

1. H\u0131z Kaynakl\u0131 Kavitasyon<\/h3>\n\n\n\n

Bir vana C de\u011ferini a\u015ft\u0131\u011f\u0131ndav<\/sub> K\u0131sma i\u015fleminde meydana gelen bas\u0131n\u00e7 d\u00fc\u015f\u00fc\u015fleri, disk \u00fczerinde kabarc\u0131k olu\u015fmas\u0131na neden olur.

2. Dinamik Tork A\u015f\u0131r\u0131 Y\u00fcklenmesi<\/h3>\n\n\n\n

M\u00fchendisler, akt\u00fcat\u00f6rlerin do\u011fru boyutunu belirlemek i\u00e7in statik oturma torkuna g\u00fcvenirler. Bununla birlikte, y\u00fcksek h\u0131zl\u0131 ak\u0131\u015f, d\u00fczensiz "kald\u0131rma" ve "s\u00fcr\u00fckleme" kuvvetleri olu\u015fturur.

4. Galvanik ve Mikrobiyolojik Etkili Korozyon (MIC)<\/h3>\n\n\n\n

Disk ve g\u00f6vde i\u00e7in uyumsuz metallerin kullan\u0131lmas\u0131, iletken ortamlarda pil etkisi yaratabilir. Ayr\u0131ca, valf g\u00f6vdesindeki "\u00f6l\u00fc b\u00f6lgelerde" anaerobik bakteriler birikerek h\u0131zl\u0131 lokal a\u015f\u0131nmaya neden olabilir. <\/p>\n\n\n\n
