Abstract

The invention relates to the technical field of test loading, and discloses a loading oil circuit and a loading test oil circuit. The first oil passage of the loading part includes a first oil inlet control valve and a first oil outlet control valve connected in parallel between the first oil port and the first loading part connection port, and the second oil passage of the loading part includes a first oil inlet control valve connected in the second The second oil inlet control valve and the second oil outlet control valve are connected in parallel between the oil port and the second loading part, and the first oil port and the second oil port are connected, so the structure of the loading oil circuit is simple, and in practice In use, after being connected with the loading part and the tested part, the stable and reliable loading test of the tested part can be realized.

Description

technical field [0001] The invention relates to the technical field of test loading, in particular to a loading oil circuit and a loading test oil circuit. Background technique [0002] At present, it is often necessary to perform a loading test on the performance of the tested piece to check whether the performance of the tested piece can meet the required requirements. [0003] In the prior art, the loading part is connected with the tested part, the loading part is connected with a loading system, the loading system includes a set of independent hydraulic pump source, and the tested part is connected with the loaded system, and the loaded system includes another set of independent hydraulic pump source. An independent hydraulic pump source usually includes a power unit, a hydraulic pump, and various types of control valves, etc., and the power unit can be a motor or a diesel engine and other power mechanisms, which constitute a set of independent hydraulic pump sources. ...
