\u010cerpadl\u00e1 a motory<\/b><\/strong><\/h2>\n

Rozdiel medzi \u010derpadlom a motorom:<\/p>\n

    \n
  1. R\u00f4zny charakter<\/li>\n<\/ol>\n

    \u010cerpadlo: \u010cerpadlo je stroj, ktor\u00fd prepravuje alebo tlakuje kvapalinu. Pren\u00e1\u0161a mechanick\u00fa energiu alebo in\u00fa vonkaj\u0161iu energiu prim\u00e1rneho pohonu na kvapalinu, \u010d\u00edm sa energia kvapaliny zvy\u0161uje.<\/p>\n

    Elektrick\u00e9 stroje: Elektrick\u00e9 stroje (v\u0161eobecne zn\u00e1me ako \"motory\") s\u00fa elektromagnetick\u00e9 zariadenia, ktor\u00e9 premie\u0148aj\u00fa alebo pren\u00e1\u0161aj\u00fa elektrick\u00fa energiu pod\u013ea z\u00e1kona elektromagnetickej indukcie.<\/p>\n

      \n
    1. R\u00f4zne funkcie<\/li>\n<\/ol>\n

      \u010cerpadlo: \u010derpadlo sa pou\u017e\u00edva najm\u00e4 na prepravu vody, oleja, kysl\u00e9ho l\u00fahu, emulzie, suspenznej emulzie a tekut\u00e9ho kovu a in\u00fdch kvapal\u00edn, ale aj na prepravu kvapal\u00edn, zmesi plynov a kvapal\u00edn obsahuj\u00facich suspendovan\u00e9 pevn\u00e9 l\u00e1tky.<\/p>\n

      Motor: Motor v obvode je vyjadren\u00fd p\u00edsmenom M (star\u00fd \u0161tandard je D), jeho hlavnou \u00falohou je vytv\u00e1ra\u0165 hnac\u00ed moment ako zdroj energie pre elektrick\u00e9 spotrebi\u010de alebo r\u00f4zne stroje, gener\u00e1tor v obvode je vyjadren\u00fd p\u00edsmenom G, jeho hlavnou \u00falohou je vyu\u017e\u00edva\u0165 mechanick\u00fa energiu na premenu na elektrick\u00fa energiu.<\/p>\n

      Ako je motor hor\u00faci?<\/p>\n

        \n
      1. Teplo motora, ktor\u00e9 vedie k hor\u00facim ruk\u00e1m<\/li>\n
      2. Ke\u010f\u017ee motor pri pr\u00e1ci produkuje pr\u00fad a elektromagnetick\u00fa indukciu, tieto energie sa premie\u0148aj\u00fa na teplo, \u010d\u00edm sa zvy\u0161uje teplota povrchu motora, \u010do vedie k hor\u00facim ruk\u00e1m.<\/li>\n
      3. Ak je motor pr\u00edli\u0161 hor\u00faci, m\u00f4\u017ee to znamena\u0165, \u017ee za\u0165a\u017eenie motora je pr\u00edli\u0161 ve\u013ek\u00e9 alebo je po\u0161koden\u00fd samotn\u00fd motor a je potrebn\u00e9 ho v\u010das zastavi\u0165 a opravi\u0165, aby sa zabezpe\u010dila bezpe\u010dnos\u0165 pou\u017e\u00edvania.<\/li>\n<\/ol>\n
