<\/figure><\/div>\n\n\n\nI. Cerin\u021be structurale <\/p>\n\n\n\n
\u00cen suprafe\u021bele de contact, se pot utiliza garnituri comprimate pentru a asigura eficacitatea etan\u0219\u0103rii incintei. Toate garniturile \u0219i etan\u0219\u0103rile trebuie s\u0103 aib\u0103 o structur\u0103 integral\u0103 continu\u0103, adic\u0103 inelar\u0103 \u0219i ne\u00eentrerupt\u0103. Structura incintei trebuie s\u0103 asigure pozi\u021bia corect\u0103 a garniturilor. <\/p>\n\n\n\n
\u00cen cazul \u00een care gradul de protec\u021bie al incintei depinde de garnitura de la \u00eembinarea incintei, iar \u00eembinarea trebuie s\u0103 fie deschis\u0103 \u00een timpul instal\u0103rii sau \u00eentre\u021binerii, garnitura trebuie s\u0103 fie lipit\u0103 sau fixat\u0103 mecanic pe una dintre suprafe\u021bele de contact pentru a preveni pierderea, deteriorarea sau instalarea incorect\u0103. Suprafe\u021bele de contact care utilizeaz\u0103 garnituri de etan\u0219are nu trebuie s\u0103 utilizeze materiale de etan\u0219are suplimentare ca mijloace auxiliare pentru performan\u021ba de etan\u0219are. <\/p>\n\n\n\n
Balamalele nu trebuie utilizate ca mijloc de men\u021binere a etan\u0219\u0103rii, cu excep\u021bia cazurilor \u00een care garnitura poate fi comprimat\u0103 \u00een mod corespunz\u0103tor f\u0103r\u0103 a provoca mi\u0219c\u0103ri nea\u0219teptate, stres sau deformare a garniturii. <\/p>\n\n\n\n
Garniturile de etan\u0219are flexibile, cum ar fi burdufurile, nu ar trebui s\u0103 fie supuse unei solicit\u0103ri excesive \u00een niciun punct. Trebuie luate m\u0103suri pentru a preveni deteriorarea mecanic\u0103 extern\u0103, iar fiecare cap\u0103t trebuie fixat mecanic. <\/p>\n\n\n\n
Not\u0103: Cerin\u021bele de mai sus nu se aplic\u0103 garniturilor din interiorul dispozitivului de introducere a cablurilor. <\/p>\n\n\n\n
II. Cerin\u021be de testare <\/p>\n\n\n\n
Dup\u0103 efectuarea testelor de carcas\u0103 \u00een conformitate cu cerin\u021bele corespunz\u0103toare, ar trebui efectuate teste de presiune pe toate probele de testare, urmate de teste privind gradul de protec\u021bie IP. <\/p>\n\n\n\n
Standardul pentru \u201cEchipamente protejate de incinte rezistente la aprinderea prafului \u2018t'\u201d \u00een medii explozive a ad\u0103ugat o cerin\u021b\u0103 de testare a presiunii pentru a evalua efectul de protec\u021bie al garniturilor \u0219i etan\u0219\u0103rilor. \u00cen mod specific, presiunea intern\u0103 trebuie s\u0103 fie de cel pu\u021bin (4 \u00b1 0,4) kPa (pentru nivelul de protec\u021bie \u2018ta\u2019) \u0219i (2 \u00b1 0,2) kPa (pentru nivelurile de protec\u021bie \u2018tb\u2019 \u0219i \u2018tc\u2019), timp de 60 p\u00e2n\u0103 la 70 de secunde. <\/p>\n\n\n\n
Trebuie men\u021bionat aici c\u0103:<\/p>\n\n\n\n
(a) Dispozitivul de introducere a cablurilor \u0219i incintele suplimentare ale echipamentelor Ex nu trebuie s\u0103 fie supuse \u00eencerc\u0103rilor de presiune, cu excep\u021bia garniturii de etan\u0219are care asigur\u0103 protec\u021bia la suprafa\u021ba \u00eembin\u0103rii de instalare a dispozitivului de introducere \u0219i a incintei; <\/p>\n\n\n\n
(b) Dac\u0103 structura echipamentului Ex poate restric\u021biona mi\u0219carea garniturilor \u0219i a etan\u0219\u0103rilor, cum ar fi inelele \u201cO\u201d \u00een caneluri sau garniturile de etan\u0219are lipite pe o parte a suprafe\u021bei \u00eembin\u0103rii, nu sunt necesare \u00eencerc\u0103ri de presiune pentru echipamentele Ex cu niveluri de protec\u021bie \u201ctb\u201d \u0219i \u201ctc\u201d.<\/p>","protected":false},"excerpt":{"rendered":"
