| 摘要 |
<p>The invention relates to a hydraulic device for measuring torque and speed, meant to be used in laboratory testing of rotary machines. According to the invention, the device consists of a reversing gear pump (1) coupled to a hydraulic reversing gear motor (2) that it supplies by means of a connection plate (3) wherein there is placed a pressure transducer (4) which sequentially receives information from both hydraulic circuits, by means of a selection valve (5), the overcharge protection or blocking protection of said circuits being also achieved by means of two limiting valves (6 and 7) placed within the connection plate (3), while a magnetic rotary transducer (8) is placed within the housing of the motor (2), adjacent to the output gear.</p> |
