Abstract

The invention discloses a hydraulic equipment on-line detection system which comprises a hydraulic cylinder, a hydraulic motor and a communication valve, the hydraulic motor and the communication valve are connected with the hydraulic cylinder in parallel, and the communication valve is connected between a rodless cavity pipeline and a rod cavity pipeline. The initial output power of the hydraulic motor is the same as the power consumed when the gate is opened and runs at a constant speed; the detection loop comprises a hydraulic motor and a communication valve, the hydraulic motor and the communication valve are connected with the hydraulic cylinder in parallel, and the communication valve is connected between the rodless cavity pipeline and the rod cavity pipeline; the detection loop comprises a flow detection unit, and the flow detection unit is arranged on a rod cavity pipeline or a rodless cavity pipeline between the hydraulic motor and the hydraulic control system. By means of the arrangement, flow detection in the hydraulic equipment can be achieved under the condition that the gate is not opened, coordination work in the gate opening and closing process is reduced, the risk of water drainage is reduced, and meanwhile the problem of water resource waste is solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy, hydropower and hydraulic equipment, in particular to an online detection system and detection method for hydraulic equipment. Background technique [0002] In water conservancy and hydropower projects, the hydraulic system can control the opening and closing of the gate. In order to ensure the normal operation of the gate, it is necessary to regularly detect the working status of the hydraulic system to ensure that the pressure and flow of the system or the speed of opening and closing the door are normal. However, the existing hydraulic system Flow detection needs to open and close the gate to carry out. Therefore, it is necessary to spend a lot of manpower to coordinate the personnel of relevant units in the river basin to take measures to release water, and at the same time, the water volume in the reservoir area of ​​the hydropower station will be wasted. Contents of the invention...
