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.

油 amount 不足会引致油 temperature easy rise high, gas easy solvent in effect/influence and liquid pressure system positive as, amount usually is or 修理时流失 致, is day 常应留意检查 has has 泄漏 部位, and more abrasion loss seals, 收紧松动 接头 and other, repair rear need 检查油箱 油 amount, and to.

liquid pressure important property 质之一 is its chemical stability property, oxidation stability property. oxidation is liquid pressure has use lifespan most main/primary factors, oxidation formed 木焦油, and and other can solvent material 会污染 liquid pressure system, increase liquid pressure parts abrasion loss, decrease/reduce various 间隙, small 孔, most make liquid pressure system fault/failure. liquid pressure oxidation speed degree 取决于本身 and as and other more factors, its in temperature degree is main/primary factors 之一, therefore need use combined liquid pressure 油, 并定期检查 liquid pressure oxidation degree （ from 油本身 color deep 而判断）, ultra- 一定数 amount as small rear 主动换油 is for necessary. 　　

    injection molding machine in use process in, need 经常检查 pressure water 平, pressure and pressure 油 清洁程 degree, to wet gas 时候, must day pressure concentrated degree, meanwhile also 需经常检查 water tube/pipe, water mixed in pressure inner, formed device retardant 塞. inner 经常检查, maintain dry 净, anti material 掉入. 按时补充 pressure 油. for/regarding lubricated 各运动部 separation, 各行程开关掣, filament 松紧以 and 各油喉, 接头部 separation is 否漏油 and other, 每周应例行检查 one-time, maintain good 状况, has 松脱, add more or 拧紧. 　　

    another, types pressure use long, can more pressure 油, this 样以便延 long 油掣, and 密封圈 lifespan.
