Embodiment Construction
[0013] Further illustrate the present invention below in conjunction with accompanying drawing.
[0014] Such as figure 1 As shown, a schematic diagram of an experimental device for testing the fluid-solid coupling relationship of a pipeline flowmeter, including a test bench 1, a fan 2, a pipeline connector 31, a tapered pipeline 32, a straight pipeline 331, a straight pipeline 332, a vibration sensor 4, and a pipeline flow rate Meter 5, clamper 61, clamper 62, clamper 63, clamper 64, vibration sensor converter 7, measurement and control system 8, upper computer 9. The test bench 1 is an anti-shock test bench, which is placed on the ground steadily and firmly to increase the stability of the device. The fan 2 is fixed near the test bench, which reduces the vibration interference caused by the fan itself. The pipeline 3 includes a pipeline connector 31 , a tapered pipeline 32 and a straight pipeline 33 . The straight pipe 33 includes a straight pipe 331 and a straight pipe 3...

The invention relates to an experiment device for pipeline flow meter fluid-solid coupling relation testing. An experiment table in the experiment device is shockproof and is firmly and fixedly placed on the ground. A draught fan is fixed to the portion near the experiment table. A pipeline comprises a pipeline connecting element, a conical pipeline body and straight pipeline bodies, a pipeline flow meter is arranged between the two straight pipeline bodies, one end of the conical pipeline body is in non-contact connection with one straight pipeline body, and the other end of the conical pipeline body is connected with the draught fan. A vibrating sensor is fixed to the metal surface of the pipeline flow meter, and the conical pipeline body, the straight pipeline bodies and the pipeline flow meter are fixedly connected to the experiment table through a clamping device. An input port of a converter of the vibrating sensor is connected with an output port of the vibrating sensor, and an output end of the converter is an open port and connected with a measurement and control system. The experiment device verifies that it is feasible to detect the flow and the flow speed of a pipeline through the pipeline flow meter. Real-time measurement of surface vibration of the flow meter and the flow speed is achieved through the simple experiment device.
Description
technical field [0001] The invention belongs to the technical field of pipeline flow metering, and relates to an experimental device for testing the fluid-solid coupling relationship of a pipeline flowmeter. Background technique [0002] The pulse type rotameter in the pipeline flowmeter mainly includes a housing, a guide, an impeller, a magnetoelectric conversion device, and the like. Its working principle is that the measured fluid impacts the blades of the impeller, causing the blades to rotate. For electric pulses with high frequency, the instantaneous flow and cumulative flow can be calculated according to the number of pulses per unit time and the cumulative number of pulses. The casing can bear the pressure of the fluid to be measured, fix guides, impellers and other components, and connect pipes. The impeller of the pulse rotameter is the detection element of the flowmeter, which receives the fluid momentum and overcomes the resistance torque. It can be made of hig...
