Hydraulic test bed

The utility model discloses a hydraulic test bed which comprises an oil tank (12). The oil tank (12) is connected with a main pump (6) and a tested pump (8) by an oil absorption filter (5); both the main pump (6) and the tested pump (8) are connected with a motor (4); the main pump (6) is connected with a throttle loading valve (26) after being connected with a first check valve (7); the tested pump (8) is connected with the throttle loading valve (26) after being connected with a second check valve (9); a first branch circuit connected by the throttle loading valve (26) is connected with a first reversing valve (21); a first quick coupling (16) and a second quick coupling (17) are connected onto the first reversing valve (21); and the first reversing valve (21) is communicated with the oil tank (12) by a loop. By using the hydraulic test bed, performance parameters of a hydraulic pump, a hydraulic valve and a hydraulic cylinder can be respectively tested. The hydraulic test bed has the advantages of testing reliability, easiness in manufacturing, convenience in maintenance and low cost.
