Abstract

The invention discloses a controllable sand flow infinitely variable speed fan blade abrasion testing device which consists of an air compressor, a gas delivery pipe, a pressure sensor, a spray gun, a sand storage chamber, a sand flow control valve, a sand pipe, a particle flow sensor, an air inlet pipeline, an erosive wear test chamber, an erosive wear test chamber upper cover, an air outlet pipeline, a deduster, a motor, a frequency converter, a fan propeller, a control cabinet, a motor bracket, an air inlet pipeline bracket, a control cabinet bracket and an angle iron bracket. A series of technical problems that the erosive wear working conditions of a rotary fan blade cannot be really simulated by a conventional erosive wear testing device are overcome.

Description

technical field [0001] The invention relates to a testing technology for the erosion and wear performance of materials, in particular to a test device for erosion of blades of a continuously variable speed fan with controllable sand flow. Background technique [0002] The starting point of the research on the erosion test device of fan blades is to analyze the gas / solid erosion wear performance and erosion wear mechanism of fan blades with different materials, configurations and shapes, and to research and develop new erosion-resistant materials and new anti-erosion wear materials. method. [0003] The erosion wear and protection of materials has always been the focus of research. In the fields of machinery, metallurgy, energy, building materials, etc., due to the erosion wear of materials, especially the erosion wear damage of fan blades, it will cause huge waste and waste every year. loss. Therefore, to study the erosion wear characteristics and mechanism of fan blades, ...
