Test \u00faniku pri rozpade tlaku<\/h2>\n\n\n\n

Ako sa vykon\u00e1va test rozpadu tlaku?<\/h2>\n\n\n\n

Ak chcete za\u010da\u0165 sk\u00fa\u0161ku tesnosti tlakov\u00fdm rozpadom, k sk\u00fa\u0161obn\u00e9mu portu sa pripoj\u00ed sk\u00fa\u0161obn\u00fd diel [TP]. Tester potom natlakuje diel tlakom [+P] na po\u017eadovan\u00fd sk\u00fa\u0161obn\u00fd tlak nastaven\u00fd regul\u00e1torom tlaku [R1] po\u010das kroku Plnenie otvoren\u00edm ventilov [V1] a [V2].<\/p>\n\n\n\n

Po dokon\u010den\u00ed kroku Naplnenie sa v diele zachyt\u00ed tlak, preto\u017ee sa uzavrie [V2]. Po miernom oneskoren\u00ed sa [V1] uzavrie, \u010d\u00edm sa potrubie medzi [V1] a [V2] odvzdu\u0161n\u00ed do atmosf\u00e9ry cez [V1], \u010do umo\u017en\u00ed, aby ak\u00fdko\u013evek \u00fanik cez [V2] sp\u00f4sobil, \u017ee tester tento \u00fanik uvid\u00ed a v\u0161etky testy nevyhovuj\u00fa. Dodato\u010dn\u00fd ventil umo\u017e\u0148uje konfigur\u00e1ciu s bezpe\u010dnos\u0165ou pri poruche.<\/p>\n\n\n\n

Zachyten\u00fd tlak v testovacom obvode sa udr\u017eiava v kroku Stabiliz\u00e1cia a potom sa meria tlakov\u00fdm sn\u00edma\u010dom [PS] testera po\u010das kroku Test.<\/p>\n\n\n\n

Ak diel prekro\u010d\u00ed naprogramovan\u00fa toleranciu netesnosti (pokles tlaku v \u010dase alebo kvantifikovan\u00e1 miera netesnosti), na displeji testera sa zobraz\u00ed d\u00f4vod zlyhania testu a zobraz\u00ed sa strata tlaku alebo miera netesnosti v mern\u00fdch jednotk\u00e1ch definovan\u00fdch pou\u017e\u00edvate\u013eom.<\/p>\n\n\n\n

Po dokon\u010den\u00ed kroku Test sa tlak zachyten\u00fd v diele vypust\u00ed do atmosf\u00e9ry cez [V1] otvoren\u00edm [V2] po\u010das kroku Vent a tester je pripraven\u00fd na \u010fal\u0161\u00ed test.<\/p>\n\n\n\n

\"Ako<\/figure>\n\n\n\n

Syst\u00e9my na testovanie rozpadu tlaku<\/h2>\n\n\n\n

Testovanie tesnosti pri rozpade tlaku<\/strong><\/a> je naj\u010dastej\u0161ie pou\u017e\u00edvanou met\u00f3dou. V\u010faka svojej jednoduchosti sa \u013eahko automatizuje a integruje do v\u00fdrobn\u00fdch\/mont\u00e1\u017enych procesov.<\/p>\n\n\n\n

Zjednodu\u0161ene povedan\u00e9, pri sk\u00fa\u0161ke poklesu tlaku sa tlakov\u00e1 n\u00e1doba napln\u00ed vzduchom, a\u017e k\u00fdm nedosiahne cie\u013eov\u00fd tlak, preru\u0161\u00ed sa zdroj vzduchu, aby sa tlak izoloval, a meria sa pokles (strata) tohto tlaku po\u010das stanoven\u00e9ho \u010dasov\u00e9ho obdobia; strata tlaku v\u00e4\u010d\u0161ia ako vopred stanoven\u00e9 nastavenie znamen\u00e1 \u00fanik. Citlivos\u0165 a presnos\u0165 merania poklesu tlaku je funkciou ve\u013ekosti sk\u00fa\u0161obnej \u010dasti a \u010dasu sk\u00fa\u0161ky. V\u00e4\u010d\u0161inu sk\u00fa\u0161ok mo\u017eno vykona\u0165 pomerne r\u00fdchlo s ve\u013emi presn\u00fdmi v\u00fdsledkami, ale \u010d\u00edm v\u00e4\u010d\u0161\u00ed je diel, t\u00fdm dlh\u0161\u00ed je \u010das cyklu, ktor\u00fd je potrebn\u00fd na dosiahnutie presn\u00e9ho v\u00fdsledku sk\u00fa\u0161ky.<\/p>\n\n\n\n

\u010co je to test \u00faniku pri tlakovom rozpade?<\/h2>\n\n\n\n

Rozpad tlaku je jedn\u00fdm z najpou\u017e\u00edvanej\u0161\u00edch
 <\/p>\n\n\n\n

Funguje to takto:<\/h3>\n\n\n\n

Pripojte svoj diel k testeru tesnosti pomocou pr\u00edslu\u0161enstva alebo pr\u00edpravku. Po\u010das f\u00e1zy plnenia je v\u00e1\u0161 diel pod tlakom.<\/p>\n\n\n\n

Po dosiahnut\u00ed po\u017eadovan\u00e9ho sk\u00fa\u0161obn\u00e9ho tlaku ur\u010den\u00e9ho v\u00fdrobcom a po uplynut\u00ed \u010dasu plnenia sa za\u010dne f\u00e1za SETTLE, ktor\u00e1 sa prisp\u00f4sob\u00ed roz\u0165ahovaniu alebo oh\u00fdbaniu dielu.<\/p>\n\n\n\n

Po ust\u00e1len\u00ed dielu a uplynut\u00ed \u010dasu ust\u00e1lenia sa spust\u00ed TEST poklesu tlaku. Po\u010das f\u00e1zy testu sn\u00edma\u010d tlaku meria ak\u00fdko\u013evek pokles tlaku.<\/p>\n\n\n\n

Po sk\u00fa\u0161ke poklesu tlaku sa zvy\u0161n\u00fd tlak v syst\u00e9me vypust\u00ed do atmosf\u00e9ry po\u010das f\u00e1zy VENT.<\/p>\n\n\n\n

Ak pokles tlaku va\u0161ej s\u00fa\u010diastky zostane v r\u00e1mci \u0161pecifik\u00e1cie, va\u0161a s\u00fa\u010diastka PR\u00cdDE a rozsvieti sa zelen\u00e9 svetlo. Ak pokles tlaku va\u0161ej s\u00fa\u010diastky klesne pod doln\u00fa hranicu, potom va\u0161a s\u00fa\u010diastka NESP\u00cd\u0160I a rozsvieti sa \u010derven\u00e1 kontrolka.<\/p>\n\n\n\n

V\u00fdhodou tohto typu testovania je, \u017ee je presn\u00e9 a\u017e na 5. desatinn\u00e9 miesto alebo 0,00001 PSI, \u010do umo\u017e\u0148uje r\u00fdchle testovacie cykly.<\/p>\n\n\n\n

Rozpad tlaku<\/strong><\/a> je jednou z najpou\u017e\u00edvanej\u0161\u00edch met\u00f3d testovania tesnosti vo v\u00fdrobe a je ide\u00e1lna pre utesnen\u00e9 komponenty s pr\u00edstupov\u00fdm otvorom. Pri tomto teste sa v\u00fdrobok pripoj\u00ed k testeru tesnosti a napln\u00ed sa vzduchom. Po stla\u010den\u00ed sa zdroj vzduchu uzavrie a tlak sa nech\u00e1 ust\u00e1li\u0165. Po\u010das testu znamen\u00e1 ak\u00fdko\u013evek pokles tlaku vzduchu v priebehu \u010dasu netesnos\u0165. Ak s\u00fa\u010diastka netesn\u00ed\/rozpad\u00e1 sa po vopred stanovenej hodnote vyradenia, je to dobr\u00e1 s\u00fa\u010diastka. Citlivos\u0165 tohto testu z\u00e1vis\u00ed od ve\u013ekosti v\u00fdrobku a \u010dasov\u00e9ho intervalu testu.
