Abstract

The invention which relates to a resistance reduction effect tester for a s viscoplastic material pipeline convey surface film belongs to experiment equipment. The tester comprises an experiment table, a mobile plate, a lifting device, a horizontal adjustment system, an air compressor and a vacuum machine. The tester is characterized in that a test plate is fixed on the mobile plate, the surface film to be tested is sprayed, and a test piece is arranged on the surface film; one end of the mobile plate is connected with the lifting device and is provided with a vertical height scale; and a frequency and amplitude adjustable vibrator is arranged on the lower surface of the mobile plate. The tester has the characteristics of simple principle, convenient calculation, real condition approach, and strong comparability. The application of the selected surface film in engineering makes the convey amount be large, the convey distance be long and consumed energy be saved. The tester is suitable for selecting and testing various resistance reduction surface films in the convey of the viscoplastic material pipeline.

Description

technical field [0001] The invention relates to a surface film selection testing instrument in pipeline transportation of viscoplastic materials, which belongs to experimental equipment. Background technique [0002] The Chinese patent surface film drag reduction method and viscoplastic material pipeline transportation technology (ZL20071026557.X) are the results of the inventor's previous research. It is a surface film drag reduction method of bionic animal intestinal membrane and body surface mucus of scaleless fish. It adopts a coating method of setting a surface film between the material and the pipeline, and a surface treatment method for reducing wall friction on the inner wall of the feeding pipeline. The internal friction of the material is much higher than the friction of the pipe wall, highlighting the problem of reducing wall friction as the main contradiction in the pipeline transportation system, and reducing many other complicated problems in the pipeline trans...
