Ako funguje sk\u00fa\u0161ka tesnosti tlakov\u00fdm rozpadom?<\/h2>\n\n\n\n

Sk\u00fa\u0161ka tesnosti tlakov\u00fdm rozkladom pozost\u00e1va z 3 krokov:<\/p>\n\n\n\n

Napl\u0148te str\u00e1nku<\/strong> - F\u013ea\u0161a sa napln\u00ed na po\u017eadovan\u00fd maxim\u00e1lny tlak, ktor\u00fd je riaden\u00fd elektronick\u00fdm regul\u00e1torom.<\/p>\n\n\n\n

T1<\/strong> - Percentu\u00e1lny pokles tlaku sa meria za ur\u010dit\u00fd \u010das. Po jeho dosiahnut\u00ed sa meria jeho v\u00fdkonnos\u0165 v porovnan\u00ed s vopred nastavenou hranicou.<\/p>\n\n\n\n

Testovanie poklesu tlaku meria nielen \u0161pi\u010dkov\u00fd tlak, ale aj zmeny tlaku v priebehu \u010dasu. To by mohlo nazna\u010dova\u0165 mal\u00fa netesnos\u0165, ktor\u00e1 sa pri jednostup\u0148ovom testovan\u00ed poklesu tlaku nemus\u00ed zachyti\u0165.<\/p>\n\n\n\n

Ur\u010dit\u00fd pokles tlaku je norm\u00e1lny aj v kvalitn\u00fdch f\u013ea\u0161iach. N\u00e1doby sa m\u00f4\u017eu pod tlakom mierne roztiahnu\u0165, k\u00fdm sa vzduch po stla\u010den\u00ed stabilizuje.<\/p>\n\n\n\n
