Abstract

The invention discloses a method and device for testing the vibration effect of a multi-combination hydraulic long pipeline system for a hydraulic system. The device comprises a fluid supply pump station, a hydraulic pipeline system and a test system, wherein in the hydraulic pipeline system, long pipelines are distributed in a space serpentine way, the middle parts of the hydraulic pipeline system are supported by detachable brackets and the switching of long and short pipelines are realized depending on electromagnetic change valves; an accessing pipeline is assembled from a high-pressure rubber pipe, a short straight pipeline, a long straight single-span pipeline, a long straight multi-span pipeline and a U-shaped pipeline; and the test system comprises pressure sensors, flowmeters, a three-way acceleration sensor, a mode analyzer and analysis software thereof.

Description

1. Technical field [0001] The invention relates to a method and device for testing the vibration effect of a multi-combination hydraulic long pipeline system, which is applied in the field of hydraulic pipeline transmission. 2. Background technology [0002] Hydraulic pipeline is one of the indispensable components of the hydraulic system, which plays the role of connection and transmission. The vibration of the pipeline will loosen the connection parts of the pipeline or cause the pipeline to break, which may cause leakage in the slightest, and cause major accidents due to explosions in severe cases. The vibration of the pipeline will in turn affect the flow of the fluid in the pipeline, forming a fluid-solid coupling system that integrates the transient flow state of the fluid, fluctuations, and pipeline vibration. At present, concrete pump trucks and shield tunneling machines, which are widely used in domestic engineering fields, have a relatively long distance between t...
