2. Klasifikace magnetick\u00fdch \u010derpadel<\/strong><\/p>\n

Existuje mnoho typ\u016f magnetick\u00fdch \u010derpadel, kter\u00e9 lze rozd\u011blit do mnoha typ\u016f podle typu, pracovn\u00edch podm\u00ednek a principu pohonu.<\/p>\n

(1) Podle r\u016fzn\u00fdch typ\u016f samotn\u00fdch \u010derpadel je lze rozd\u011blit na odst\u0159ediv\u00e1 \u010derpadla s magnetick\u00fdm pohonem, zubov\u00e1 \u010derpadla s magnetick\u00fdm pohonem, \u0161roubov\u00e1 \u010derpadla s magnetick\u00fdm pohonem atd., mezi nimi\u017e jsou odst\u0159ediv\u00e1 \u010derpadla s magnetick\u00fdm pohonem hlavn\u00edm typem v sou\u010dasnosti pou\u017e\u00edvan\u00fdch magnetick\u00fdch \u010derpadel;<\/p>\n

(2) Podle r\u016fzn\u00fdch pracovn\u00edch podm\u00ednek je lze rozd\u011blit na b\u011b\u017en\u00e1 magnetick\u00e1 \u010derpadla, vysokoteplotn\u00ed magnetick\u00e1 \u010derpadla a magnetick\u00e1 \u010derpadla odoln\u00e1 proti korozi;<\/p>\n

(3) Podle r\u016fzn\u00fdch princip\u016f magnetick\u00e9ho pohonu je lze rozd\u011blit na magnetick\u00e1 \u010derpadla se synchronn\u00edm magnetick\u00fdm pohonem a magnetick\u00e1 \u010derpadla s asynchronn\u00edm magnetick\u00fdm pohonem.<\/p>\n

3. Konstruk\u010dn\u00ed vlastnosti magnetick\u00e9ho \u010derpadla (odst\u0159ediv\u00e9ho typu)<\/strong><\/p>\n

Magnetick\u00e9 \u010derpadlo se skl\u00e1d\u00e1 p\u0159edev\u0161\u00edm z t\u011blesa \u010derpadla, ob\u011b\u017en\u00e9ho kola, vnit\u0159n\u00edch a vn\u011bj\u0161\u00edch h\u0159\u00eddel\u00ed, magnetick\u00e9ho spojovac\u00edho mechanismu, kluzn\u00e9ho lo\u017eiska, spojky a motoru.<\/p>\n

(1) Magnetick\u00fd spojovac\u00ed mechanismus. Magnetick\u00fd spojovac\u00ed mechanismus magnetick\u00e9ho \u010derpadla se skl\u00e1d\u00e1 z vnit\u0159n\u00edch a vn\u011bj\u0161\u00edch magnetick\u00fdch v\u00e1lc\u016f a izola\u010dn\u00edch pouzder. Vnit\u0159n\u00ed a vn\u011bj\u0161\u00ed magnetick\u00e9 v\u00e1lce magnetick\u00e9ho \u010derpadla jsou permanentn\u00ed magnety vyroben\u00e9 ze sud\u00fdch p\u00e1r\u016f permanentn\u00edch magnetick\u00fdch materi\u00e1l\u016f vz\u00e1cn\u00fdch zemin, kter\u00e9 jsou uspo\u0159\u00e1d\u00e1ny a rozm\u00edst\u011bny v pravideln\u00e9m vzoru. Provozn\u00ed teplota m\u016f\u017ee dos\u00e1hnout -45 ~ 100 \u2103 a sm\u011br magnetick\u00e9ho pole permanentn\u00edho magnetu m\u00e1 dobrou anizotropii a nen\u00ed n\u00e1chyln\u00fd k demagnetizaci.<\/p>\n

Izola\u010dn\u00ed pouzdro magnetick\u00e9ho \u010derpadla je v\u011bt\u0161inou vyrobeno z nemagnetick\u00fdch kovov\u00fdch nebo keramick\u00fdch materi\u00e1l\u016f, aby zcela ut\u011bsnilo \u010derpan\u00e9 m\u00e9dium a vnit\u0159n\u00ed magnetick\u00fd v\u00e1lec.<\/p>\n

(2) Kluzn\u00e1 lo\u017eiska. Vzhledem k tomu, \u017ee kluzn\u00e1 lo\u017eiska magnetick\u00fdch \u010derpadel jsou samomazn\u00e1 dopravovan\u00fdm m\u00e9diem, je t\u0159eba pro v\u00fdrobu lo\u017eisek zvolit r\u016fzn\u00e9 materi\u00e1ly podle r\u016fzn\u00fdch dopravovan\u00fdch m\u00e9di\u00ed, mezi nimi\u017e se pou\u017e\u00edvaj\u00ed p\u0159edev\u0161\u00edm keramick\u00e1 lo\u017eiska z karbidu k\u0159em\u00edku a grafitov\u00e1 lo\u017eiska.<\/p>\n

Keramick\u00e1 lo\u017eiska z karbidu k\u0159em\u00edku maj\u00ed silnou nosnost a jsou mimo\u0159\u00e1dn\u011b odoln\u00e1 v\u016f\u010di erozi, chemick\u00e9 korozi, opot\u0159eben\u00ed a teplu. Provozn\u00ed teplota m\u016f\u017ee dos\u00e1hnout p\u0159ibli\u017en\u011b 500 \u00b0C a \u017eivotnost je pom\u011brn\u011b dlouh\u00e1, obvykle dosahuje v\u00edce ne\u017e 3 a.<\/p>\n

Ve srovn\u00e1n\u00ed s keramick\u00fdmi lo\u017eisky z karbidu k\u0159em\u00edku maj\u00ed grafitov\u00e1 lo\u017eiska dobrou samomaznost a vydr\u017e\u00ed kr\u00e1tkodob\u00fd chod na sucho. Grafitov\u00e1 lo\u017eiska mohou odol\u00e1vat teplot\u00e1m a\u017e do p\u0159ibli\u017en\u011b 450 \u00b0C, ale vzhledem k jejich n\u00edzk\u00e9 odolnosti proti opot\u0159eben\u00ed bude jejich \u017eivotnost krat\u0161\u00ed ne\u017e u lo\u017eisek z karbidu k\u0159em\u00edku.<\/p>\n

(3) Chladic\u00ed a mazac\u00ed syst\u00e9m. Kdy\u017e je magnetick\u00e9 \u010derpadlo v chodu, vznik\u00e1 v oblasti prstencov\u00e9 mezery mezi vnit\u0159n\u00edm magnetick\u00fdm v\u00e1lcem a izola\u010dn\u00edm pouzdrem vysok\u00e1 teplota zp\u016fsoben\u00e1 magnetick\u00fdmi v\u00ed\u0159iv\u00fdmi proudy. K proplachov\u00e1n\u00ed a chlazen\u00ed oblasti prstencov\u00e9 mezery mezi vnit\u0159n\u00edm magnetick\u00fdm v\u00e1lcem a izola\u010dn\u00edm pouzdrem a t\u0159ec\u00ed dvojic\u00ed kluzn\u00e9ho lo\u017eiska je t\u0159eba pou\u017e\u00edt mal\u00e9 mno\u017estv\u00ed m\u00e9dia. Proplachovac\u00ed m\u00e9dium odvede vysokou teplotu, a t\u00edm zajist\u00ed bezpe\u010dn\u00fd provoz magnetick\u00e9ho \u010derpadla.<\/p>\n

Pokud nen\u00ed chlazen\u00ed a maz\u00e1n\u00ed uvnit\u0159 magnetick\u00e9ho \u010derpadla dostate\u010dn\u00e9, teplota m\u00e9dia v oblasti prstencov\u00e9 mezery bude vy\u0161\u0161\u00ed ne\u017e pracovn\u00ed teplota permanentn\u00edho magnetu, co\u017e zp\u016fsob\u00ed, \u017ee vnit\u0159n\u00ed magnetick\u00fd v\u00e1lec postupn\u011b ztrat\u00ed sv\u016fj magnetismus a magnetick\u00fd p\u0159enos sel\u017ee. Proto magnetick\u00e9 \u010derpadlo vy\u017eaduje, aby bylo zaru\u010deno mno\u017estv\u00ed chladic\u00edho a mazac\u00edho 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.
