Defin\u00edcia<\/strong><\/p>\n

1 Rota\u010dn\u00e9 \u010derpadlo<\/p>\n

Rota\u010dn\u00e9 \u010derpadl\u00e1 sa naz\u00fdvaj\u00fa aj koloidn\u00e9 \u010derpadl\u00e1, va\u010dkov\u00e9 \u010derpadl\u00e1, trojlistov\u00e9 \u010derpadl\u00e1 alebo univerz\u00e1lne dod\u00e1vkov\u00e9 \u010derpadl\u00e1 at\u010f. a s\u00fa to objemov\u00e9 \u010derpadl\u00e1. Na dosiahnutie \u00fa\u010delu dopravy kvapal\u00edn vyu\u017e\u00edva periodick\u00fa premenu viacer\u00fdch pevn\u00fdch objemov\u00fdch v\u00fdtla\u010dn\u00fdch jednotiek v pracovnej komore.<\/p>\n

2 Odstrediv\u00e9 \u010derpadlo<\/p>\n

Princ\u00edpom \u010dinnosti odstrediv\u00e9ho \u010derpadla je odstrediv\u00fd pohyb. Odstrediv\u00fd pohyb je vlastne prejavom zotrva\u010dnosti objektu. Napr\u00edklad ke\u010f sa kvapky vody na d\u00e1\u017edniku pomaly ot\u00e1\u010daj\u00fa, kvapky vody sa bud\u00fa ot\u00e1\u010da\u0165 spolu s d\u00e1\u017ednikom. Je to preto, lebo trenie medzi d\u00e1\u017ednikom a kvapkami vody p\u00f4sob\u00ed na kvapky vody ako dostrediv\u00e1 sila. Ak sa v\u0161ak d\u00e1\u017ednik ot\u00e1\u010da r\u00fdchlej\u0161ie, trenie nesta\u010d\u00ed na to, aby sa kvapky vody pohybovali kr\u00fa\u017eiv\u00fdm pohybom. Vtedy sa kvapky vody odtrhn\u00fa od d\u00e1\u017ednika a presun\u00fa sa k vonkaj\u0161iemu okraju, podobne ako ke\u010f pomocou lana \u0165ah\u00e1me kame\u0148, aby vykonal kruhov\u00fd pohyb. Ak je r\u00fdchlos\u0165 pr\u00edli\u0161 vysok\u00e1, lano sa pretrhne a kame\u0148 vylet\u00ed von. Ide o takzvan\u00fd odstrediv\u00fd pohyb.<\/p>\n

Ke\u010f odstrediv\u00e9 \u010derpadlo pracuje, vysokor\u00fdchlostn\u00e9 rotuj\u00face lopatky obe\u017en\u00e9ho kolesa poh\u00e1\u0148aj\u00fa kvapalinu, aby sa ot\u00e1\u010dala a vyhadzovala kvapalinu von, \u010d\u00edm sa dosiahne \u00fa\u010del prepravy. Pred pr\u00e1cou odstrediv\u00e9ho \u010derpadla sa teleso \u010derpadla a pr\u00edvodn\u00e9 potrubie vody musia naplni\u0165 kvapalinou, aby sa vytvoril v\u00e1kuov\u00fd stav. Ke\u010f sa obe\u017en\u00e9 koleso r\u00fdchlo ot\u00e1\u010da, lopatky sp\u00f4sobuj\u00fa r\u00fdchle ot\u00e1\u010danie kvapaliny. Rotuj\u00faca kvapalina vylet\u00ed z obe\u017en\u00e9ho kolesa p\u00f4soben\u00edm odstredivej sily. Po vyvrhnut\u00ed kvapaliny v \u010derpadle sa v strede obe\u017en\u00e9ho kolesa vytvor\u00ed oblas\u0165 v\u00e1kua. Vonkaj\u0161ia kvapalina sa vtl\u00e1\u010da do pr\u00edvodn\u00e9ho potrubia vody cez potrubn\u00fa sie\u0165 p\u00f4soben\u00edm atmosf\u00e9rick\u00e9ho tlaku a mo\u017eno dosiahnu\u0165 nepretr\u017eit\u00fa dopravu.<\/p>\n

3 Skrutkov\u00e9 \u010derpadlo<\/p>\n

Skrutkov\u00e9 \u010derpadlo je nov\u00fd typ \u010derpadla, ktor\u00e9 funguje na princ\u00edpe rota\u010dn\u00e9ho ot\u00e1\u010dania s kladn\u00fdm v\u00fdtlakom. Hlavn\u00fdmi pracovn\u00fdmi \u010das\u0165ami s\u00fa excentrick\u00e1 skrutka (rotor) a pevn\u00e9 puzdro (stator). V\u010faka \u0161peci\u00e1lnemu geometrick\u00e9mu tvaru t\u00fdchto dvoch \u010dast\u00ed sa vytv\u00e1raj\u00fa samostatn\u00e9 utesnen\u00e9 komory. M\u00e9dium je tla\u010den\u00e9 a pr\u00fadi rovnomerne v axi\u00e1lnom smere, r\u00fdchlos\u0165 vn\u00fatorn\u00e9ho pr\u00fadenia je n\u00edzka, objem zost\u00e1va nezmenen\u00fd a tlak je stabiln\u00fd, tak\u017ee sa nevytv\u00e1raj\u00fa v\u00edriv\u00e9 pr\u00fady a mie\u0161anie.<\/p>\n

Okrem toho maj\u00fa skrutkov\u00e9 \u010derpadl\u00e1 tieto v\u00fdhody:
\n1) \u0160irok\u00fd rozsah tlaku a prietoku. Tlak je pribli\u017ene 3,4-340 kg*N\/c\u33a1 a prietok m\u00f4\u017ee dosiahnu\u0165 300-3000 m3;
\n2) \u0160irok\u00fd rozsah typov a viskoz\u00edt prepravovan\u00fdch kvapal\u00edn;
\n3) Ke\u010f\u017ee zotrva\u010dn\u00e1 sila rotuj\u00facich \u010dast\u00ed \u010derpadla je n\u00edzka, mo\u017eno pou\u017ei\u0165 ve\u013emi vysok\u00e9 ot\u00e1\u010dky;
\n4) Dobr\u00fd sac\u00ed v\u00fdkon a siln\u00e1 samonas\u00e1vacia schopnos\u0165;
\n5) Rovnomern\u00fd a nepretr\u017eit\u00fd prietok, mal\u00e9 vibr\u00e1cie, n\u00edzka hlu\u010dnos\u0165 a dlh\u00e1 \u017eivotnos\u0165;
\n6) V porovnan\u00ed s in\u00fdmi rota\u010dn\u00fdmi \u010derpadlami je menej citliv\u00e9 na vstupuj\u00faci plyn a ne\u010distoty;
\n7) Pevn\u00e1 kon\u0161trukcia a jednoduch\u00e1 in\u0161tal\u00e1cia a \u00fadr\u017eba.<\/p>\n

Porovnanie<\/strong><\/p>\n

1. Porovnanie rotorov\u00e9ho \u010derpadla a jednoskrutkov\u00e9ho \u010derpadla
\n1) Rotor \u010derpadla m\u00f4\u017ee be\u017ea\u0165 nasucho, \u010do je d\u00f4le\u017eit\u00e9 najm\u00e4 v pr\u00edpade n\u00e1hlej poruchy materi\u00e1lu alebo prev\u00e1dzkov\u00fdch ch\u00fdb, \u010d\u00edm sa zabr\u00e1ni po\u0161kodeniu \u010derpadla a zabezpe\u010d\u00ed sa bezpe\u010dn\u00e1 prev\u00e1dzka.
\n2) rotorov\u00e9 \u010derpadlo m\u00e1 mal\u00e9 rozmery, tretinu in\u0161tala\u010dnej plochy jednoskrutkov\u00e9ho \u010derpadla, \u010d\u00edm sa zni\u017euje rozsah a n\u00e1klady na stavebn\u00e9 pr\u00e1ce.
\n3) Rotorov\u00e9 \u010derpadlo mo\u017eno opravi\u0165 online bez demont\u00e1\u017ee potrubia, \u010do je pohodln\u00e9 a r\u00fdchle, \u010d\u00edm sa skracuje \u010das odst\u00e1vky.
\n4) Princ\u00edp pr\u00e1ce bez vytl\u00e1\u010dania rotorov\u00e9ho \u010derpadla a nastavite\u013en\u00e1 kon\u0161trukcia pl\u00e1\u0161\u0165a predl\u017euj\u00fa \u017eivotnos\u0165, zni\u017euj\u00fa po\u010det \u00fadr\u017ebov\u00fdch cyklov a \u0161etria n\u00e1klady na n\u00e1hradn\u00e9 diely.<\/p>\n

2. Porovnanie skrutkov\u00e9ho a odstrediv\u00e9ho \u010derpadla
\n1) Ke\u010f sa plyn dostane do dutiny \u010derpadla, odstrediv\u00e9 \u010derpadlo pracuje ve\u013emi nestabilne, \u00fa\u010dinnos\u0165 sa v\u00fdrazne zni\u017euje, \u010derpadlo ve\u013emi vibruje a kavit\u00e1cia je v\u00e1\u017ena. Skrutkov\u00e9 \u010derpadlo m\u00f4\u017ee dobre realizova\u0165 zmie\u0161an\u00fa dopravu plynu, kvapaliny a pevnej l\u00e1tky.
\n2) R\u00fdchlos\u0165 odstrediv\u00e9ho \u010derpadla je vo v\u0161eobecnosti ve\u013emi vysok\u00e1, a\u017e tis\u00edce ot\u00e1\u010dok za min\u00fatu, a strihov\u00e1 vlastnos\u0165 m\u00e9dia je ve\u013emi ve\u013ek\u00e1; skrutkov\u00e9 \u010derpadlo zvy\u010dajne pracuje pri n\u00edzkych ot\u00e1\u010dkach, aby sa zabezpe\u010dilo, \u017ee nedoch\u00e1dza k pulzom a vibr\u00e1ci\u00e1m, a aby sa realizovala preprava bez strihu.
\n3) Ke\u010f sa odstrediv\u00e9 \u010derpadlo pou\u017e\u00edva na prepravu m\u00e9di\u00ed, ke\u010f sa m\u00e9dium stane visk\u00f3znym, prietok alebo tlak prudko klesne. Skrutkov\u00e9 \u010derpadlo je vhodnej\u0161ie na prepravu m\u00e9di\u00ed s vysokou viskozitou a vysok\u00fdm obsahom pevn\u00fdch l\u00e1tok.<\/p>\n
