1. Povolte pojistnou matici pr\u016ftoku<\/strong><\/p>\n\n\n\n

Prvn\u00edm krokem p\u0159i nastavov\u00e1n\u00ed pr\u016ftoku hlavn\u00edho \u010derpadla je uvoln\u011bn\u00ed pojistn\u00e9 matice pr\u016ftoku. Tato matice zaji\u0161\u0165uje \u0161roub pro nastaven\u00ed pr\u016ftoku na m\u00edst\u011b a zabra\u0148uje necht\u011bn\u00e9mu nastaven\u00ed b\u011bhem provozu.

Tento \u0161roub reguluje tlak v hydraulick\u00e9m syst\u00e9mu a zaji\u0161\u0165uje jeho provoz v bezpe\u010dn\u00fdch mez\u00edch. Pe\u010dliv\u011b sledujte manometr, abyste dos\u00e1hli po\u017eadovan\u00e9ho tlaku.<\/p>\n\n\n\n

3. Jemn\u00e9 dolad\u011bn\u00ed \u0161roubu pro nastaven\u00ed pr\u016ftoku<\/strong><\/p>\n\n\n\n

Se\u0159\u00edzen\u00ed \u0161roubu pro nastaven\u00ed pr\u016ftoku je choulostiv\u00fd proces.
