1. Magnetini\u0173 siurbli\u0173 kavitacijos sukeliamos problemos:<\/p>\n

Pagrindin\u0117s kavitacijos siurbliuose prie\u017eastys yra didelis pasiprie\u0161inimas siurblio \u012fsiurbimo vamzdyje, daugiau duj\u0173 faz\u0117s transportin\u0117je terp\u0117je, nepakankamas siurblio u\u017epildymas, nepakankama siurblio \u012fleidimo galvut\u0117 ir kt. Kavitacija labiausiai kenkia siurbliui. \u012evykus kavitacijai, siurblys smarkiai vibruoja ir smarkiai pa\u017eeid\u017eiama pusiausvyra, tod\u0117l pa\u017eeid\u017eiami siurblio guoliai, rotoriai arba sparnuot\u0117s. Tai da\u017ena magnetinio siurblio gedimo prie\u017eastis.<\/p>\n

2. N\u0117ra vidutinio arba nedidelis perne\u0161amos terp\u0117s srautas:<\/p>\n

Rotoriaus pagrindinis velenas ir stabilus guolis sausai trinami, tod\u0117l guolis sudega. Magnetin\u012f siurbl\u012f tepa ir au\u0161ina slankiojo guolio transportavimo terp\u0117. Nesant \u012fleidimo arba i\u0161leidimo vo\u017etuvo, slankiojam\u0105j\u012f guol\u012f pa\u017eeid\u017eia auk\u0161ta temperat\u016bra, nes n\u0117ra transportin\u0117s terp\u0117s tepimo ir au\u0161inimo.<\/p>\n

3. Neleiskite dalel\u0117ms patekti \u012f vid\u0173:<\/p>\n

1). Feromagnetin\u0117s priemai\u0161os ir dalel\u0117s negali patekti \u012f magnetin\u0117s transmisijos ir guolio trinties por\u0105.<\/p>\n

2). Perne\u0161dami lengvai kristalizuojan\u010dias ar nuos\u0117das kaupian\u010dias terpes, laiku jas i\u0161plaukite (sustabd\u0119 siurbl\u012f pripildykite siurblio ertm\u0119 \u0161varaus vandens, o po 1 minut\u0117s darbo j\u012f i\u0161leiskite), kad u\u017etikrintum\u0117te slankiojan\u010diojo guolio tarnavimo laik\u0105.<\/p>\n

3). Kai transportuojama terp\u0117, kurioje yra kiet\u0173j\u0173 daleli\u0173, ji turi b\u016bti filtruojama siurblio srauto vamzd\u017eio \u012f\u0117jime.<\/p>\n

4. Izoliacin\u0117s movos pa\u017eeidimas:<\/p>\n

Magnetinio siurblio magnetin\u0119 mov\u0105 au\u0161ina siurblio transportuojama terp\u0117. Jei terp\u0117je yra kiet\u0173 daleli\u0173, ant izoliacin\u0117s movos lengvai atsiranda \u012fbr\u0117\u017eim\u0173 ar \u012fskilim\u0173. Kartais d\u0117l netinkam\u0173 technin\u0117s prie\u017ei\u016bros metod\u0173 taip pat gali b\u016bti pa\u017eeista izoliacin\u0117 mova.<\/p>\n

5. U\u017ekirskite keli\u0105 sausai trin\u010diai:<\/p>\n

1). Grie\u017etai draud\u017eiama veikti tu\u0161\u010di\u0105ja eiga.<\/p>\n

2). Vidutin\u0117 evakuacija grie\u017etai draud\u017eiama.<\/p>\n

3). Kai i\u0161leidimo vo\u017etuvas u\u017edarytas, siurblio nepertraukiamo veikimo trukm\u0117 neturi vir\u0161yti 2 minu\u010di\u0173, kad magnetin\u0117 pavara neperkaist\u0173 ir nesugest\u0173.<\/p>\n

6. U\u017ekirskite keli\u0105 demagnetizacijai:<\/p>\n

1). Magnetinis sukimo momentas negali b\u016bti per ma\u017eas.<\/p>\n

2). Jis tur\u0117t\u0173 b\u016bti eksploatuojamas laikantis nurodyt\u0173 temperat\u016bros s\u0105lyg\u0173, o terp\u0117s temperat\u016bra grie\u017etai draud\u017eiama vir\u0161yti standart\u0105. Ant magnetin\u0117s siurblio izoliacin\u0117s \u012fvor\u0117s i\u0161orinio pavir\u0161iaus galima \u012frengti platinos var\u017eos temperat\u016bros jutikl\u012f, kad b\u016bt\u0173 galima aptikti temperat\u016bros padid\u0117jim\u0105 \u017eiedinio tarpo zonoje ir, temperat\u016brai vir\u0161ijus rib\u0105, paskelbti pavojaus signal\u0105 arba i\u0161jungti siurbl\u012f.<\/p>\n
