The best Hydraulic headbox is generally composed of three main parts: distributor, weir pool and weir plate.
1. Spreader. The distributor of the best hydraulic headbox is composed of a square cone distribution main pipe and a series of pipe bundles connected to the weir pool on its side. Its function is to evenly distribute the paper stock into the weir pool of the best hydraulic headbox, so that the web material is uniform along the full width of the paper machine.

2. Weir pool. The weir pool is the main component of the hydraulic headbox, and its function is to disperse the flocs of the fibers according to the speed requirements of the paper machine, and maintain a stable flow rate of the paper stock. It is ensured that the online paper material in the best hydraulic headbox can be evenly dispersed on the Internet and eliminates the speed gradient of the paper material on the Internet.
3. Weir plate. The weir plate is the online device of the best hydraulic headbox. The paper material is ejected from the shotcrete port of the weir plate, and under the action of the upper and lower weir plates, the ejected paper material is uniformly sprayed to the mesh of the best hydraulic headbox along the full width and at a certain flow rate and angle. surface to form a uniform wet sheet.
