Abstract

The invention discloses an integrated forming process of a high-power wind power motor cabin cover, and belongs to the field of wind power motor cabin cover forming processes. According to the integrated forming process of the high-power wind power motor cabin cover, the high-power wind power motor cabin cover is integrally formed by utilizing a vacuum introduction process, so that the performanceof the motor cabin cover is greatly improved; the bending strength of the resin of the adopted gel coat can reach 310MPa after being cured, the tensile strength is not lower than 180MPa, the elongation is not larger than 4%, and the thermal deformation temperature reaches up to 80 DEG C; the flame-retardant resin coating on the surface of the cabin cover has good water resistance, alkali resistance, scrubbing resistance, pollution resistance, temperature change resistance, flame retardance and the like, the oxygen index is not lower than 28, the performance requirements of the cabin cover onrigidity strength, corrosion resistance and ultraviolet resistance can be well met, in the vacuum introduction integrated forming process, hidden bubbles in the formed main material resin are removedby utilizing a bubble removing device, and the strength of the motor cabin cover is greatly improved.

Description

technical field [0001] The invention relates to the field of forming technology of a wind-powered motor nacelle, and more specifically, relates to an integrated molding process of a high-power wind-powered motor nacelle. Background technique [0002] As a clean energy technology, wind power has developed relatively mature and stable around the world. Medium and large wind turbines have been connected to the grid in more than 40 countries around the world. At present, my country's wind power industry has entered the stage of quality and technology competition, and the quality level of the complete unit has increasingly become the focus of China's wind power industry. For the complete wind turbine, the quality status of parts is one of the most important factors affecting its quality. At the same time, different types of parts have different effects on the whole machine. By analyzing the influence factors and degree of different parts on the whole machine, the risk of engine...
