The design of the central feeding system adopts vacuum pipeline vision transmission, will fight through the laying of pipe conveying system reasonably concentrated plastic raw materials to the dryer system, after drying the plastic raw materials will be transported to each injection molding machine are in demand. The central feeding system adopts "design plane charge", guarantees the entire central air feeding system for raw material conveying, and prevent will have the raw material after drying dehumidifying resurgence. When the central feeding abnormal noise, said system is equipment parts damage or improper adjustment, should be part of a noise feeding system and identify the reasons for timely maintenance position.
1, when the lack of hydraulic oil feeding system lubricating oil tank, oil pump suction air filter or dirt blocking will cause the pump oil, causing bubbles in the oil discharge machine blade generated noise, the solution is to check the amount of oil, prevent inhalation of air and clean the oil filter.
2, the hydraulic oil of high viscosity, increase flow resistance, hydraulic oil to replace the central feeding system verification.
3, due to the oil pump or click on the bearing or blade damage, coupling concentricity deviation caused by noise, need to adjust concentricity or replacement parts.
4, the central feeding system direction valve failure but still in the reaction function, such as heart valve wear, internal leakage, obstruction, burr movement is not flexible, because the current lack of solenoid valve failure will produce noise, the solution is cleaning the spool, spool wear should be replaced with new parts, stable and sufficient current.
5, hydraulic components damaged or blocked road pipeline to make high-speed flow of hydraulic oil noise.
6, the mechanical part of the fault, bearing wear or mechanical lack of lubricating oil or loose parts, should find out the reasons for fastening or replacement parts, to ensure adequate oil.
