Pompada Hangi Vana Kullan\u0131l\u0131r?<\/h2>\n\n\n\n

Bir pompalama sistemi tipik olarak \u00fc\u00e7 valf gerektirir: bir giri\u015f (emme) kapatma valfi, bir \u00e7\u0131k\u0131\u015f (de\u015farj) kapatma valfi ve ters ak\u0131\u015f\u0131 \u00f6nlemek ve koruma sa\u011flamak i\u00e7in pompa bo\u015faltma a\u011fz\u0131 ile bo\u015faltma kapatma valfi aras\u0131nda bir \u00e7ek valf. Pompay\u0131 kar\u015f\u0131 bas\u0131n\u00e7tan koruyun.<\/p>\n\n\n\n

Bazen, pompan\u0131n \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flamak veya ters d\u00f6n\u00fc\u015ften korumak i\u00e7in giri\u015f borusuna bir dip vanas\u0131 tak\u0131labilir. Bununla birlikte, mevcut net pozitif emme y\u00fcksekli\u011fine darbeler ve su darbesi riski (pompa ak\u0131\u015f h\u0131z\u0131ndaki ani bir de\u011fi\u015fikli\u011fin neden oldu\u011fu bas\u0131n\u00e7 dalgalanmas\u0131) gibi taban vanalar\u0131n\u0131n potansiyel dezavantajlar\u0131 dikkate al\u0131nmal\u0131d\u0131r.<\/p>\n\n\n\n

Pompadaki vanalar, pompadaki s\u0131v\u0131n\u0131n ak\u0131\u015f\u0131n\u0131 kontrol eder.

Bu, her bir valfin geni\u015fli\u011finin bir \u00f6l\u00e7\u00fc olarak kullan\u0131lmas\u0131yla belirlenebilir. \u00d6rne\u011fin, bir pompan\u0131n 1 in\u00e7 giri\u015fi ve \u00bd in\u00e7 \u00e7\u0131k\u0131\u015f\u0131 varsa, bu durumda bir vana emme taraf\u0131ndan en az 10 in\u00e7 ve basma taraf\u0131ndan 5 in\u00e7 uza\u011fa yerle\u015ftirilmelidir.<\/p>\n\n\n\n
