Problems solved by technology

[0004] In summary, the above-mentioned pressure wave generators have different design starting points and are suitable for their own design purposes. However, for the evaluation and detection of abnormal pipeline conditions, they are also not suitable for liquid working fluid environments, and the pressure wave signal strength generated is not large. There is leakage in the device itself, or technical problems such as uncontrollable continuous pressure wave excitation frequency

Abstract

The invention discloses a mechanically driven continuous impact pressure wave generator and a pipeline abnormal state detection device based on it, which belongs to the technical field of pipeline detection. , the plunger rod connector, and the piston sleeve are on the same axis, so the operation is stable and the device has a long service life; driven by the spring force and the motor, the plunger can quickly hit the diaphragm with the linear movement of the plunger rod in the piston sleeve , using the deformation of the diaphragm to generate pulsed pressure fluctuations, and then propagate along the pipeline; the diaphragm isolates the fluid in the flow pipe from the gas in the piston sleeve, and still has a good sealing function under high pressure. The new structural method of using the motor to provide mechanical energy, spring and flywheel to store energy enables the overall equipment to generate continuous pressure waves; the overall device is positioned by the main body fixing frame, the device is compact in space, easy to carry, easy to operate, and has high man-machine friendliness Sex; simple structure, good sealing, stable operation.

Description

technical field [0001] The invention belongs to the technical field of pipeline detection, and relates to a mechanically driven continuous impact pressure wave generator and a pipeline abnormal state detection device based on it. Background technique [0002] In petrochemical, energy, chemical, metallurgy, pharmaceutical, water treatment and many other industrial processes, traces of pressure waves may appear when fluid flows in industrial piping systems and major equipment. The transmission of pressure fluctuations reflects the process of media carrying energy and propagating information, so there are many applications of pressure wave generators. As a carrier for transmitting information, pressure waves can be used to evaluate pipeline abnormalities, including leakage, blockage, abnormal branches, and abnormal pipe diameters. The potential safety hazards and indirect economic benefit losses caused by abnormal pipelines will have a serious impact on people's life safety an...
