Abstract
The utility model relates to a bi-directional closed type loading return circuit system in a test platform of a hydraulic motor. The bi-directional closed type loading return circuit system in the test platform of the hydraulic motor comprises an oil tank, a high-pressure oil pump and a tested motor. The high-pressure oil pump which is connected with the oil tank is in connection with an oil inlet of the tested motor through a hydraulic flexible pipe. An oil outlet of the tested motor is connected with a main flow quantity sensor and forms a motor testing return circuit through the oil return tank of an oil return filter.

The rotation speed sensor is in connection with a loading pump through a coupling. An oil suction opening and an oil outlet of the loading pump are connected with a bridge type one-way valve. High-pressure outlet oil of the loading pump enters a loading pressure adjusting valve, a lost pressure difference is converted into heat in an overflow valve, and hot oil is cooled after passing through a cooler and returns to the oil suction of the loading pump through the bridge type one-way valve. Compared with the prior art, the bi-directional closed type loading return circuit system in the test platform of the hydraulic motor has the advantages that the loading pump is tiny in structure and high in power density, due to the fact that no electromagnetic device is arranged, interference is reduced, the suction type oil cooler is adopted, a cooling water system can be removed, and loading test can be conducted for a long time.
