Abstract
The invention relates to a vibration test device for a pipeline. The device comprises a sample pipe fitting, a pipe, a ball valve and an eccentric wheel, wherein both ends of the sample pipe fitting are provided with a connecting pipe with the length of 200mm respectively; the middle of one connecting pipe is provided with a joint, and the other end of the connecting pipe is provided with a vibration end; the end of the other connecting pipe is provided with the ball valve; and the outside of the vibration end of the connecting pipe is provided with a power eccentric wheel. The device has the advantages of: applying hydraulic pressure to a pipeline to achieve a certain value through the port of the ball valve according to test requirements; closing the ball valve; vibrating the pipeline through the eccentric wheel, fixing one end near a test piece, connecting the end with a hydraulic pressure test pump, pressurizing to achieve 1.75 MPa during operation, wherein a test medium is tap water; vibrating the other end of the test piece, performing the vibration test condition according to requirements; making the test pressure be 1.75 MPa during the vibration test; and continuing vibrating for 100 thousand times under the pressure, wherein phenomena of leakage and falling-off do not exist on the joints of the pipe fitting and carbon steel pipes.
