TEST STAND FOR GEAR OIL PUMPS AND FULL-FLOW OIL CENTRIFUGES Russian patent published in 2006 - IPC F04C2/08 G01M15/00 

FIELD: mechanical engineering; testing facilities.

SUBSTANCE: proposed invention is designed for testing gear oil pumps of internal combustion engines and full-flow oil centrifuges. Stand contains drive shaft for connecting shaft of pump 4 to be tested, hydraulic system with hydraulic tank 19, suction hydraulic line 23 whose input is connected to hydraulic tank 19 and output is designed for connecting to inlet hole of pump 4, pressure hydraulic line 24 whose input is to be connected to outlet hole of pump 4, drain hydraulic line 25, hydraulic line 27 for testing centrifuge 6 whose input is connected to pressure hydraulic line 24 and output, to hydraulic tank 19, and also means for mounting pump 4 and centrifuge 6 on stand, and adjustable restrictor 10. devices for determining capacity of pump 4 include shaft speed pickup 16 of pump 4, pulse counter 14 with indicator and on/off member, liquid meter 15 with corresponding on/off member, and two-way cock 13 with change-over handle. Output of pickup 16 is connected to pulse counter 14, input and first output of cock 13 are connected to drain hydraulic line 25, second output of cock 13 is connected to input meter 15 whose output is connected to drain hydraulic line 25 after point of connection of first output of cock 13, and change-over handle is coupled with on/off members of pulse counter 14 and liquid meter 15 to provide simultaneous switching on of said devices with delivery of working liquid from second output of cock 13 to input of liquid meter 15 and simultaneous switching off of said devices with cutting off delivery of working liquid to input of liquid meter 15.

EFFECT: enlarged functional capabilities at increased accuracy of determination of capacity of pump under testing.
