English term or phrase:Reverse Bubble Point Testing
E un test cu bule pentru un cartus filtrant, In mare intai se introduce aer la presiune mai ridicata si se urmareste frecventa bulelor, apoi se scade presiunea la jumatate si se observa daca exista zone pe unde nu apar bule.
Explanation: Testele pentru determinarea punctului de barbotare pot fi facute prin cresterea presiunii pana la presiunea nominala a filtrului.
Aceasta metoda se mai numeste si "metoda primei bule".
“A reverse bubble test (sometimes referred to as a first bubble test) detects defects by looking for bubbles while a wetted filter is submersed in a liquid. With the filter wetted and liquid covering one side of the filter, a gas at constant and/or variable pressure is directed against the other side of the filter.” http://www.freepatentsonline.com/5576480.html

(a) Filtrul este intact, aerul nu trece deloc prin membrana si nu avem nici bule de aer in apa; (b) Filtrul este rupt sau la punctul de barbotare, aerul trece prin membrana, bule de aer in apa. Punctul de barbotare ar trebui sa fie mai mare sau egal decat presiunea maxima inscrisa pe specificatia filtrului. http://proiecte.nipne.ro/pn2/propethad/PROPETHAD_Faza3_01062...
“The procedure for bubble-point test is described in American Society for Testing and Materials Standard (ASMT) Method F316. The top of the filter is placed in contact with the liquid, the bottom with air, the filter holder is connected to a source of a regulated pressure. The air pressure is gradually increased and the formation of bubbles on the liquid side is noted. At pressures below the bubble point, gas passes across the filter only by diffusion, but when the pressure is high enough to dislodge liquid from the pores, bulk flow begins and bubbles will be seen.” http://www.lenntech.com/library/fine/bubble/bubble-point.htm
La presiunea maxima, pentru un filtru bun, normal, se produc bule in zona centrala, si numai dupa ce s-a ajuns la presiunea respectiva. Nu cred ca este vorba de reducerea la jumatate, v-as ruga sa verificati textul, se pare ca presiunea este redusa pana la formarea primelor bule, de aceea se si numeste "metoda primei bule".

Dupa cum spun referintele de mai sus, testarea punctului de barbotare se poate face la presiune fixa, variabila, crestere sau descrestere. Termenul de mai sus se face prin scaderea presiunii.
E vorba despre un fragment de text pentru un test si am o saptamana si jumatate de cand dorm doar 4 ore pe noapte. Sunt pur si simplu epuizat. Dar asta e meseria noastra chiar daca e prost platita la noi in tarisoara. Daca aveti nevoie de ajutor sa stiti ca sunt disponibil :)
Va multumesc din nou si va doresc o zi buna.
