Abstract. This paper presents the procedure for an endurance test
conducted on the micro pumps for bearings lubrication in turbojet engines.
The endurance test was carried out on the test rig installation using a
procedure for a working regime simulation of the micro pumps. Analysis
and evaluation of the investigation results are performed on the basis
of the mathematical statistics methods.
Key words: Turbojet engine, lubrication system, micro pumps,
endurance test.
TEST IZDRŽLJIVOSTI MIKRO PUMPI ZA PODMAZIVANJE
LEŽAJEVA TURBOMLAZNIH MOTORA
Rad prikazuje proceduru testa izdržljivosti sprovedenu na mikro pumpama
za podmazivanje ležajeva turbomlaznog motora. Test izdžljivosti izvršen
je u laboratorijskim uslovima, na ispitnom uređaju, simuliranjem režima
rada mikropumpi. Analiza i ocena rezultata ispitivanja izvršena je na osnovu
metoda matematičke statistike.
Ključne reči: Turbomlazni motor, sistem za podmazivanje, mikro
pumpe, test izdžljivosti.
