Abstract
The invention discloses a circular erosion test device for closed pipelines. The circular erosion test device comprises a stirring device, a measuring device, a control device, a calibrating device and a pipeline device, wherein a medium is stirred in the stirring device, and then is conveyed to the measuring device for measuring through the pipeline device; the measuring device is connected with the control device; the control device is used for acquiring and adjusting the measurement data obtained by the measuring device; the calibrating device is connected with the measuring device and used for calibrating; the pipeline device comprises a stainless steel pipeline, and a to-be-tested pipeline which is a replaceable pipeline; the control device adopts a center console which comprises a data acquisition module, a temperature control module and a pressure control module. The circular erosion test device has the advantages that various factors are comprehensively considered, the actual working condition can be simulated, and the test results are more accurate.
Description
technical field [0001] The invention relates to a test device and a use method thereof, in particular to a closed pipeline cyclic erosion test device and a use method thereof. Background technique [0002] In the pipeline transportation process of industrial production, the fluid in the pipeline usually contains solid impurities of different particle sizes. When the fluid containing solid impurities is transported in the pipeline at a higher temperature, pressure and flow rate, these solid impurities will be at a certain angle Impact wear and chemical corrosion on the inner wall of the transportation pipeline, that is, the erosion phenomenon, lead to the loss of the quality of the inner wall of the pipeline, especially when the flow field changes drastically, such as elbows, tees, sudden expansion pipes, sudden shrinkage pipes, and method In typical parts such as flange joints, the severity of erosion is far more than that of straight pipe sections. When erosion continues t...
