How CNC machine tool manufacturers prevent solid impurities from entering the hydraulic system
所使用的液压油在液压系统中起着传递压力、润滑、冷却、密封的作用，液压油选择不恰当是液压系统早期故障和耐久性下降的主要原因，应按随机《使用说明书》中规定的牌号选择液压油，特殊情况需要使用代用油时，应力求其性能与原牌号性能相同。 The hydraulic oil used by CNC hydraulic machine tool manufacturers plays the role of transmitting pressure, lubrication, cooling, and sealing in the hydraulic system. Improper selection of hydraulic oil is the main reason for the early failure and durability decrease of the hydraulic system. 》 Selected hydraulic oil for the grades specified in》. In special cases when alternative oil is required, the performance should be the same as that of the original grade.
Different grades of hydraulic oil cannot be mixed to prevent chemical reactions and changes in performance of the hydraulic oil. Dark brown, milky white, and odorous hydraulic oil cannot be used as deteriorated oil. Clean hydraulic oil is driven by the hydraulic system.
There are many precision parts in the hydraulic system, some have damping holes, some have gaps, etc. If solid impurities invade, the precision parts will be injured, card issue, oil passage blocked, etc., endangering the safe operation of the hydraulic system.
可以从以下几个方面防止固体杂质入侵系统： Generally, the way solid impurities invade the hydraulic system includes dirty hydraulic oil, dirty refueling tools, careless repair and maintenance, and descaling of hydraulic components. CNC machine tool manufacturers can prevent solid impurities from invading the system from the following aspects:
1. When refueling: The hydraulic oil must be filtered and refilled. The refueling tools should be cleaned reliably. The filter at the fuel filler of the fuel tank should not be removed in order to increase the refueling speed. Refuelers should use clean gloves and work clothes to prevent solid impurities and fiber impurities. Fall into the oil.
2. During maintenance: Remove the hydraulic fuel tank filler cap, filter cover, detection hole, hydraulic oil pipe and other parts, which will avoid dust when the system oil duct is exposed, and the disassembled parts must be cleaned thoroughly before opening.
For example, when removing the filler cap of the hydraulic oil tank, first remove the dirt around the fuel tank cap, loosen the fuel tank cap, and remove the debris remaining at the joints, and then confirm the cleaning before opening the fuel tank cap. If you need to use a wiping material and a hammer, you should Choose a wiping material that does not lose fiber impurities and a special hammer with rubber attached to the hitting surface.
提醒用户安装滤芯前应用擦拭材料认真清洁滤清器壳内底部污物。 The hydraulic components and hydraulic hoses should be carefully cleaned and assembled after being blown dry with high pressure air. Select a well-packed genuine filter element and clean the filter at the same time when changing the oil. CNC hydraulic machine tool manufacturers remind users to carefully clean the filter before installing the filter element. Dirt on the bottom of the case.
