Jednostup\u0148ov\u00e9 odst\u0159ediv\u00e9 horizont\u00e1ln\u00ed \u010derpadlo NCU je ur\u010deno k doprav\u011b kyselin a jin\u00fdch chemicky aktivn\u00edch a korozivn\u00edch kapalin.<\/p>

Konstruk\u010dn\u00ed proveden\u00ed<\/h6>

Hydraulickou \u010d\u00e1st \u010derpadla tvo\u0159\u00ed stator a rotor. Stator tvo\u0159\u00ed sac\u00ed v\u00edko, ve kter\u00e9m je vypou\u0161t\u011bc\u00ed otvor a spir\u00e1ln\u00ed sk\u0159\u00ed\u0148 s v\u00fdtla\u010dn\u00fdm hrdlem. Rotor tvo\u0159\u00ed h\u0159\u00eddel, ne n\u011bm\u017e je letmo ulo\u017eeno na trnu se z\u00e1vitem otev\u0159en\u00e9 ob\u011b\u017en\u00e9 kolo s t\u011bsn\u00edc\u00edm kruhem na stran\u011b ucp\u00e1vky. Mechanickou \u010d\u00e1st tvo\u0159\u00ed kozl\u00edk, v n\u011bm\u017e je ulo\u017een h\u0159\u00eddel ve valiv\u00fdch lo\u017eisk\u00e1ch s olejov\u00fdm maz\u00e1n\u00edm.<\/p>

Materi\u00e1l<\/h6>

Spir\u00e1la, sac\u00ed v\u00edko a vlo\u017eka ob\u011b\u017en\u00e9ho kola jsou ze \u0161ed\u00e9 litiny. Plochy, kter\u00e9 p\u0159ich\u00e1zej\u00ed do styku s \u010derpanou kapalinou jsou opat\u0159eny 5 mm silnou vrstvou gumy (proveden\u00ed GC) nebo polopropylenu (proveden\u00ed HC).<\/p>

Ucp\u00e1vka<\/h6>

Ucp\u00e1vka se vol\u00ed v\u017edy s ohledem na \u010derpanou kapalinu a m\u016f\u017ee b\u00fdt v n\u011bkolika alternativ\u00e1ch m\u011bkk\u00e1 provazcov\u00e1 ve v\u0161ech alternativ\u00e1ch nebo mechanick\u00e1 keramick\u00e1 ucp\u00e1vka. Oba druhy ucp\u00e1vek jsou lehce vz\u00e1jemn\u011b vym\u011bniteln\u00e9.<\/p>

Technick\u00e9 parametry<\/h6>

Maxim\u00e1ln\u00ed teplota dopravovan\u00e9 kapaliny: 160\u00b0C
Pr\u016ftok \u010derpadla: Q = 0,83 – 150 l\/s
Dopravn\u00ed v\u00fd\u0161ka: H = 90 5 m<\/p>
