Magnetick\u00e9 \u010derpadlo sa sklad\u00e1 z troch \u010dast\u00ed: motora, magnetick\u00e9ho spojovacieho mechanizmu a \u010derpadla. Kr\u00fatiaci moment vyvoden\u00fd motorom sa pren\u00e1\u0161a na obe\u017en\u00e9 koleso prostredn\u00edctvom magnetick\u00e9ho spojovacieho mechanizmu (vn\u00fatorn\u00e9 a vonkaj\u0161ie magnetick\u00e9 valce), \u010d\u00edm sa dosiahne \u00fa\u010del prepravy m\u00e9dia.<\/p>\n

2. Klasifik\u00e1cia magnetick\u00fdch \u010derpadiel<\/strong><\/p>\n

Existuje mnoho typov magnetick\u00fdch \u010derpadiel, ktor\u00e9 mo\u017eno rozdeli\u0165 do mnoh\u00fdch typov pod\u013ea typu, pracovn\u00fdch podmienok a princ\u00edpu pohonu.<\/p>\n

(1) Pod\u013ea r\u00f4znych typov samotn\u00fdch \u010derpadiel ich mo\u017eno rozdeli\u0165 na odstrediv\u00e9 \u010derpadl\u00e1 s magnetick\u00fdm pohonom, zubov\u00e9 \u010derpadl\u00e1 s magnetick\u00fdm pohonom, skrutkov\u00e9 \u010derpadl\u00e1 s magnetick\u00fdm pohonom at\u010f., medzi ktor\u00fdmi s\u00fa odstrediv\u00e9 \u010derpadl\u00e1 s magnetick\u00fdm pohonom hlavn\u00fdm typom magnetick\u00fdch \u010derpadiel pou\u017e\u00edvan\u00fdch v s\u00fa\u010dasnosti;<\/p>\n

(2) Pod\u013ea r\u00f4znych pracovn\u00fdch podmienok ich mo\u017eno rozdeli\u0165 na be\u017en\u00e9 magnetick\u00e9 \u010derpadl\u00e1, vysokoteplotn\u00e9 magnetick\u00e9 \u010derpadl\u00e1 a magnetick\u00e9 \u010derpadl\u00e1 odoln\u00e9 vo\u010di kor\u00f3zii;<\/p>\n

(3) Pod\u013ea r\u00f4znych princ\u00edpov magnetick\u00e9ho pohonu ich mo\u017eno rozdeli\u0165 na magnetick\u00e9 \u010derpadl\u00e1 so synchr\u00f3nnym magnetick\u00fdm pohonom a magnetick\u00e9 \u010derpadl\u00e1 s asynchr\u00f3nnym magnetick\u00fdm pohonom.<\/p>\n

V s\u00fa\u010dasnosti v\u00e4\u010d\u0161ina magnetick\u00fdch \u010derpadiel pou\u017e\u00edva synchr\u00f3nny magnetick\u00fd pohon. Magnetick\u00e9 \u010derpadlo s asynchr\u00f3nnym magnetick\u00fdm pohonom pou\u017e\u00edva kr\u00fatiaci kr\u00fa\u017eok s klietkou, ktor\u00fd nahr\u00e1dza vn\u00fatorn\u00fd magnetick\u00fd valec, a generuje o nie\u010do ni\u017e\u0161ie ot\u00e1\u010dky prostredn\u00edctvom elektromagnetick\u00e9ho po\u013ea. Teplota, pri ktorej sa tento typ magnetick\u00e9ho \u010derpadla m\u00f4\u017ee pou\u017e\u00edva\u0165, je vy\u0161\u0161ia ako teplota magnetick\u00e9ho \u010derpadla so synchr\u00f3nnym magnetick\u00fdm pohonom.<\/p>\n

3. Kon\u0161truk\u010dn\u00e9 vlastnosti magnetick\u00e9ho \u010derpadla (odstrediv\u00e9ho typu)<\/strong><\/p>\n

Magnetick\u00e9 \u010derpadlo sa sklad\u00e1 najm\u00e4 z telesa \u010derpadla, obe\u017en\u00e9ho kolesa, vn\u00fatorn\u00e9ho a vonkaj\u0161ieho hriade\u013ea, magnetick\u00e9ho spojovacieho mechanizmu, klzn\u00e9ho lo\u017eiska, spojky a motora.<\/p>\n

(1) Magnetick\u00fd spojovac\u00ed mechanizmus. Magnetick\u00fd spojovac\u00ed mechanizmus magnetick\u00e9ho \u010derpadla sa sklad\u00e1 z vn\u00fatorn\u00fdch a vonkaj\u0161\u00edch magnetick\u00fdch valcov a izola\u010dn\u00fdch puzdier. Vn\u00fatorn\u00e9 a vonkaj\u0161ie magnetick\u00e9 valce magnetick\u00e9ho \u010derpadla s\u00fa permanentn\u00e9 magnety vyroben\u00e9 z p\u00e1rnych dvoj\u00edc permanentn\u00fdch magnetick\u00fdch materi\u00e1lov vz\u00e1cnych zem\u00edn, ktor\u00e9 s\u00fa usporiadan\u00e9 a rozmiestnen\u00e9 v pravidelnom vzore. Prev\u00e1dzkov\u00e1 teplota m\u00f4\u017ee dosiahnu\u0165 -45 ~ 100 \u2103 a smer magnetick\u00e9ho po\u013ea permanentn\u00e9ho magnetu m\u00e1 dobr\u00fa anizotropiu a nie je n\u00e1chyln\u00fd na demagnetiz\u00e1ciu.<\/p>\n

Izola\u010dn\u00e9 puzdro magnetick\u00e9ho \u010derpadla je v\u00e4\u010d\u0161inou vyroben\u00e9 z nemagnetick\u00fdch kovov\u00fdch alebo keramick\u00fdch materi\u00e1lov, aby \u00faplne utesnilo \u010derpan\u00e9 m\u00e9dium a vn\u00fatorn\u00fd magnetick\u00fd valec.<\/p>\n

(2) Klzn\u00e9 lo\u017eisk\u00e1. Ke\u010f\u017ee klzn\u00e9 lo\u017eisk\u00e1 magnetick\u00fdch \u010derpadiel s\u00fa samomazan\u00e9 dopravovan\u00fdm m\u00e9diom, na v\u00fdrobu lo\u017e\u00edsk by sa mali zvoli\u0165 r\u00f4zne materi\u00e1ly pod\u013ea r\u00f4znych dopravovan\u00fdch m\u00e9di\u00ed, medzi ktor\u00fdmi sa pou\u017e\u00edvaj\u00fa najm\u00e4 keramick\u00e9 lo\u017eisk\u00e1 z karbidu krem\u00edka a grafitov\u00e9 lo\u017eisk\u00e1.<\/p>\n

Keramick\u00e9 lo\u017eisk\u00e1 z karbidu krem\u00edka maj\u00fa siln\u00fa nosnos\u0165 a s\u00fa mimoriadne odoln\u00e9 vo\u010di er\u00f3zii, chemickej kor\u00f3zii, opotrebovaniu a teplu. Prev\u00e1dzkov\u00e1 teplota m\u00f4\u017ee dosiahnu\u0165 pribli\u017ene 500 \u00b0C a \u017eivotnos\u0165 je pomerne dlh\u00e1, spravidla dosahuje viac ako 3 roky.<\/p>\n

V porovnan\u00ed s keramick\u00fdmi lo\u017eiskami z karbidu krem\u00edka maj\u00fa grafitov\u00e9 lo\u017eisk\u00e1 dobr\u00fa samomaznos\u0165 a vydr\u017eia kr\u00e1tkodob\u00fd chod na sucho. Grafitov\u00e9 lo\u017eisk\u00e1 vydr\u017eia teploty a\u017e do pribli\u017ene 450 \u00b0C, ale vzh\u013eadom na ich slab\u00fa odolnos\u0165 proti opotrebovaniu bude ich \u017eivotnos\u0165 krat\u0161ia ako \u017eivotnos\u0165 lo\u017e\u00edsk z karbidu krem\u00edka.<\/p>\n

(3) Chladiaci a mazac\u00ed syst\u00e9m. Ke\u010f je magnetick\u00e9 \u010derpadlo v prev\u00e1dzke, v oblasti prstencovej medzery medzi vn\u00fatorn\u00fdm magnetick\u00fdm valcom a izola\u010dn\u00fdm puzdrom sa v d\u00f4sledku magnetick\u00e9ho v\u00edriv\u00e9ho pr\u00fadu vytv\u00e1ra vysok\u00e1 teplota. Na preplachovanie a chladenie oblasti prstencovej medzery medzi vn\u00fatorn\u00fdm magnetick\u00fdm valcom a izola\u010dn\u00fdm puzdrom a trecej dvojice klzn\u00e9ho lo\u017eiska sa mus\u00ed pou\u017ei\u0165 mal\u00e9 mno\u017estvo m\u00e9dia. Preplachovacie m\u00e9dium odvedie vysok\u00fa teplotu, \u010d\u00edm sa zabezpe\u010d\u00ed bezpe\u010dn\u00e1 prev\u00e1dzka magnetick\u00e9ho \u010derpadla.<\/p>\n

Ak chladenie a mazanie vo vn\u00fatri magnetick\u00e9ho \u010derpadla nie je dostato\u010dn\u00e9, teplota m\u00e9dia v oblasti kruhovej medzery bude vy\u0161\u0161ia ako pracovn\u00e1 teplota permanentn\u00e9ho magnetu, \u010do sp\u00f4sob\u00ed, \u017ee vn\u00fatorn\u00fd magnetick\u00fd valec postupne strat\u00ed svoj magnetizmus a magnetick\u00fd prenos zlyh\u00e1. Preto magnetick\u00e9 \u010derpadlo vy\u017eaduje, aby bolo zaru\u010den\u00e9 mno\u017estvo chladiaceho a mazacieho m\u00e9dia.<\/p>","protected":false},"excerpt":{"rendered":"

1. Principle of magnetic pump The magnetic pump consists of three parts: motor, magnetic coupling mechanism and pump.
