[0001] The present application relates to fan detection equipment technical field, especially to a kind of composite material pultruded profile fan cover detection equipment. BACKGROUND
[0002] Fan cover is the key protective component of fan equipment, which provides physical protection for the internal components of fan equipment. According to the structure, fan cover can be divided into centrifugal fan cover, axial fan cover and mixed flow fan cover. The manufacturing material of composite material pultruded profile fan cover is usually composed of glass fiber reinforced material and unsaturated polyester resin. The performance of composite material pultruded profile fan cover is excellent, and the weight is light, which helps to reduce the overall weight of fan, reduces the difficulty of installation and transportation, and has considerable strength, which can withstand harsh environment and mechanical stress. In the prior art, drop hammer impact testing machine and pendulum hammer impact testing machine are often used to conduct impact test on fan cover to detect the impact resistance of fan cover. Since the fibers of composite material pultruded profile are arranged in a specific direction during production to enhance the mechanical properties in a specific direction, the fiber orientation of the outer surface and the inner surface of fan cover may be slightly different due to different molding processes. For example, during winding or layering process, the fibers close to the outer side may be more inclined to distribute in the circumferential direction to resist external pressure, while the internal fibers may have more advantages in axial enhancement. Therefore, the impact test results of the outer side and the inner side of composite material pultruded profile fan cover are different, and the drop hammer impact testing machine and the pendulum hammer impact testing machine can only conduct impact test on the outer side of the composite material pultruded profile fan cover, which causes limitation.
