The invention discloses a unilateral pouring method for the web of a
wind power blade, which comprises mold preparation, laying of the lower layer of release cloth, laying of the lower layer of the sheet, laying of the PVC sheet, laying of the upper layer of the sheet, laying of the
lightning protection wire, preheating of the mold, Laying of the upper layer of release cloth, laying of auxiliary materials, vacuum infusion, solidification of the web, and finally the production of the web, wherein, in the process of laying the auxiliary materials, it is segmented from the blade root to the blade tip at the side of the outer edge of the mold Lay the spiral
pipe, lay the flow channel from the blade root to the blade tip on the other side of the outer edge of the mold, and lay the diversion net under the flow channel. At the same time, the spiral
pipe is sealed and connected to the
buffer tank, and the
buffer tank is sealed to connect the
vacuum pump. The spiral tube is placed on one side of the mold, and the spiral tube is connected to the
buffer tank through the
vacuum tube, and the buffer tank is connected to the
vacuum pump. The spiral tube replaces the vacuum device on the original mold, reducing the consumption of the more expensive steel wire spiral tube. The road is laid in sections, which saves the amount of auxiliary materials and reduces the production cost of the web.
