Problems solved by technology
[0004] However, under the action of vacuum negative pressure, the glue injection pipe will press the glass fiber cloth layer on the lower side, resulting in indentation of the glue injection pipe on the inner surface of the cured product, which reduces the product quality, and the repair of the indentation requires high maintenance costs

Abstract
The invention discloses a vacuum pouring method and a vacuum pouring device for a cabin cover of a wind turbine generator, and relates to the technical field of wind power generation equipment. The vacuum pouring method and the vacuum pouring device mainly aim to prevent the inner surface of a cured product from forming a glue injection pipe indentation so as to ensure the product quality and reduce the maintenance cost. According to the main technical scheme, the vacuum pouring method of the cabin cover of the wind turbine generator comprises the steps that a supporting part is arranged on aflow guide net, and a glue injection pipe is supported in the supporting part to form a flow guide assembly; a laying material and the flow guide assembly are laid on a mold in sequence, wherein a gapis formed between the glue injection pipe and the laying material; the laying material and the flow guide assembly are vacuumized; and resin is injected into the glue injection pipe.
Description
technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a vacuum infusion method and a vacuum infusion device for a wind turbine nacelle cover. Background technique [0002] Wind energy is a very important safe and clean energy with huge reserves. Wind power generation is the main form of wind energy utilization. The nacelle cover of the wind turbine is used as the protective shell of the wind turbine. Its reliability determines the stability and service life of the wind turbine. . [0003] At present, the nacelle cover is usually manufactured by the vacuum infusion molding process, that is, after laying glass fiber cloth, isolation film, release cloth, etc. The injection pipe is arranged, and the vacuum infusion can be carried out after the vacuum system is arranged. [0004] However, under the action of vacuum negative pressure, the glue injection pipe will press the glass fiber cloth layer on the lower sid...
