The hydraulic headbox is different from the traditional air cushion or open type headbox. The hydraulic headbox uses hydraulic pressure to control the flow rate and uniformity of the pulp. The hydraulic device will generate stable pressure to deliver the pulp from the pulp delivery pipe to the nozzle and evenly distribute it over the entire width of the forming mesh. During this process, the hydraulic control system inside the headbox accurately adjusts the pulp to ensure a stable and uniform pulp flow.
(1) Precise pressure control: Sun Hong adopts a fully enclosed design and uses a hydraulic pressure system to adjust the speed and uniformity of the pulp flow to meet the needs of high speed operation.
(2) High pulp flow uniformity: Equipped with flow distribution devices such as flow equalizers and uniform velocity cones, it effectively reduces pulp flow turbulence and ensures uniform pulp distribution.
(3) Strong adaptability: It can be flexibly adjusted according to different paper types and production processes, suitable for the production of high-quality paper grades.
(4) Energy saving and environmental protection: Optimize the pulp flow path and system design to reduce energy consumption, pulp waste and bubble problems.
