due to injection molding machine lubricated relatively more, need lubricant how much 也各不一样, also has lubricated lubricated 泵 远近 different belt/tape tube/pipe pressure loss has difference, 我们必 must in lubricated and lubricated between 设置流 amount separation device, it is lubricated system core parts, has retardant resistant 式, 容积式, 递进式三 large type:

separation device as principle is in tube/pipe upper small 通道, increase retardant function, it can for amount ratio/proportion separation 配, separation device front rear lubricant pressure effect/influence relatively large, is types most simple, separation device.

谓螺旋 retardant resistant 式, is in standards 孔(精 degree can processing is H7至H6 grade) in surface has 螺旋槽 small 间隙配 combined rod (状如螺钉), control 螺旋槽 deep degree and long degree control retardant large small; small ring retardant resistant 式, is in standards in 放入直径 relatively small rod, and rod between has ring 隙, through control rod large small adjustment ring large small, 同样, small and rod can processing long, can ring control small 一, therefore easy 发生堵塞.

retardant resistant separation device is structure 紧凑, 经济, as, 维护方便, increase decrease lubricated 点自由, currently in small type injection molding machine upper using/adopting.

容积式 separation device from as principle upper separation is add pressure 容积式 and pressure 容积式. add pressure 容积式, is lubricated 泵输送 pressure 油推动计 amount parts inner active 塞, will upper already in amount inner lubricant strong/high made pressure toward lubricated 点, lubricated 泵停止供油而卸 pressure 时, active in elastic force function lower 复位, good lower 次 供油.

pressure 容积式, is amount parts inner active in lubricated 泵输送 pressure 油 推动 lower 储存油, lubricated 泵停止供油而卸 pressure 时, active in elastic force function lower 排油. can 知, add pressure 容积式 can high pressure to lubricated 点供油, can property versus for relatively high. from as principle upper can 知, 容积式 separation device can in lubricated as, machine, 卸荷一 循 ring in one-time; and, in elastic 簧复位缓 slow, for tube/pipe pressure requirements high, its “工 as efficiency ” low, especially is injection molding machine one-time 试车时, has 部位需油 amount large, add and other time relatively long.

also has, separation device inner has 橡胶, elastic and other parts, can property and resistant pressure is very high, this is its defect. 容积式 separation device is lubricant to amount 精确, can 靠, can for system pressure testing, increase decrease lubricated 点方便, cost versus for retardant resistant relatively high, in in type injection molding machine upper using/adopting relatively more.

separation device basic as principle, is utilizing liquid pressure 递进式动 as. is in separation device inner 各 工 as 柱塞副, in front as 柱塞副 循 ring as rear, 各自工 as formed 自己 柱塞行程, amount lubricant to lubricated 点.

need has pressure lubricant to separation device, as 柱塞副就会以递进式 methods 运行, 并以恒定 排 amount 注油. rear, 一旦供 to pressure lubricant flow 停止, that separation device as 柱塞也就停止运动. tool has pressure lubricant from new flow 时, separation device inner as also in 同一点 again it 注油循 ring as.

递进式 separation device from structure upper separation has formed and sheet/slice type. formed separation device is 一整 阀体, structure 紧凑, relatively 方便, 但阀体 generally is aluminum alloy, 螺纹口 easy loss bad, but also, in non positive high pressure as and 阀体间隙会变 large, from generate 泄漏, 递进式动 as 会错误 继续进行, also has, formed separation device 每孔排 amount same, comparison difficult 以适应 injection molding machine has multiple amount requirements.

sheet/slice block amount has multiple specifications, can according to different need 搭配, degree relatively large, its disadvantages is large heavy, separation block between combined difficult 免发生泄漏. 递进式 separation device has features is its certain 一点发生堵塞时整 顺序动 as 便会停止, this to for it belt/tape large benefits.
