The invention belongs to an energy accumulator technique, and discloses a flow test device of an energy accumulator. The flow test device comprises an oil tank, a pump unit, a measuring oil cylinder,a blocking oil cylinder, an unloading overflow valve, a control valve, a first pressure gage assembly, a first electromagnetic valve, control energy accumulators, a second pressure gage assembly and aback pressure throttle valve, wherein a measuring piston is arranged in the measuring oil cylinder, and a displacement sensor is installed on the measuring piston; a stop block is fixed to the end ofthe measuring piston, a blocking piston is arranged in the blocking oil cylinder, and a stop rod which is used for limiting the stop block to move is arranged on the end of the blocking piston. The flow test device has the advantage of simplicity in operation; the displacement sensor and the pressure gage assemblies are arranged in the measuring oil cylinder, so that the energy release process can be completely recorded, and the flow characteristic detection in the energy release process is realized.
Description
technical field [0001] The invention belongs to accumulator technology, in particular to an accumulator flow test device. Background technique [0002] An accumulator is an energy storage device in a hydropneumatic system. It converts the energy in the system into compression energy or potential energy at an appropriate time and stores it. When the system needs it, it converts the compression energy or potential energy into hydraulic or pneumatic energy and releases it to supply the system again. When the pressure of the system increases instantaneously, it can absorb this part of the energy to ensure the normal pressure of the whole system. [0003] During the manufacturing process of the accumulator, it is necessary to test the accumulator, the purpose is to ensure the production quality of the accumulator and the working state of the accumulator in use. [0004] When the accumulator is working, it will release energy after storing energy. The process of releasing energy...
