         injection molding machine temperature rise high large 危害: make machine generate hot deformation, viscosity reduce, seals deformation, accelerated liquid oxidation 变质, meanwhile make gas separation force pressure reduce.

        一, make machine generate hot deformation

         liquid pressure parts in hot 胀系数 different 运动部 parts its combined 见习变 small 而卡死, 引起动 as 失灵, effect/influence liquid pressure system 传动精 degree, 导致部 parts as quality 变差.

        二, make viscosity reduce

         injection molding machine temperature rise high will 导致油 viscosity reduce, increase, 泵 容积 efficiency and system efficiency significantly reduce. due to viscosity reduce, slip and other 移动部 parts film thin and by 切破, scratch retardant force increase large, abrasion loss add 剧.

        三, make seals deformation

         injection molding machine temperature rise high make seals deformation, accelerated aging 失效, reduce property can and use lifespan, formed 泄漏.

        四, accelerated liquid oxidation 变质

         injection molding machine temperature rise high accelerated liquid oxidation 变质, 析出沥青 material 质, reduce liquid pressure use lifespan. material retardant small and 缝隙式阀口, pressure 阀卡死而不 can as, metal tube/pipe long bending, 甚至破裂 and other.

        五, 导致部 parts as quality 变差

         injection molding machine temperature rise high 会导致部 parts as quality 变差, in solvent understanding gas 逸出, generate gas 穴, make liquid pressure system as property can reduce.

         liquid pressure system 理想工 as temperature degree 应介乎45 degree -50 degree between, causes is liquid pressure system is based on 一选定 pressure viscosity design, viscosity 会随 油 temperature high low 而变化, effect/influence system in as parts, 如油缸, liquid pressure and other, make control degree and 响应灵敏 degree reduce, for/regarding precision injection machine 情况尤甚.

         meanwhile temperature degree high accelerated seals aging its hard 化, 碎裂; temperature degree low processing can amount consumption large, make speed degree reduce. therefore attention/notes liquid pressure 油 工 as temperature degree is separation necessary. temperature high causes more 样, more 归于油路 fault/failure or cooling system and other.
