空气对挖掘机液压油污染的危害

日期:2022-11-28   来源:http://www.dybocheng.com
加长臂挖掘机液压油污染在使用过程中会时有发生,那么这个问题是比较关键的,要及时进行处理,下面来讲讲空气对加长臂挖掘机液压油污染的危害。
The hydraulic oil pollution of the extended boom excavator will occur from time to time during use, so this problem is more critical and should be handled in a timely manner. Next, we will talk about the harm of air to the hydraulic oil pollution of the extended boom excavator.
(1)产生空穴、气蚀作用,导致金属和密封材料的破坏;产生噪音、振动和爬行现象,降低液压系统的稳定性。
(1) Cavitation and cavitation are generated, which leads to the destruction of metal and sealing materials; Produce noise, vibration and creeping, and reduce the stability of the hydraulic system.
(2)使液压泵的容积效率下降,能量损失增大,液压系统不能发挥应有的效能。
(2) The volumetric efficiency of the hydraulic pump decreases, the energy loss increases, and the hydraulic system cannot play its due role.
(3)液压油导热性变差,油温升高,引起化学变化。
(3) The thermal conductivity of hydraulic oil becomes poor, and the oil temperature rises, causing chemical changes.

进空气的主要原因及其解决措施:
Main causes of air intake and solutions:
(1)接头松动或油封、密封环损坏而吸入空气。液压系统应有良好的密封性,各接头应牢牢固定,并确保油箱密封完好,这样可防止外界空气进入而污染系统。
(1) The joint is loose or the oil seal and sealing ring are damaged, which causes air intake. The hydraulic system shall have good sealing performance. All joints shall be firmly fixed and the oil tank shall be well sealed, so as to prevent external air from entering and polluting the system.
(2)吸油管路及连接系统的管路被磨穿、擦破或腐蚀而使空气进入。应合理设计液压系统结构,使管路走向布局合理化;要保持管路的清洁,减少外界腐蚀。
(2) The oil suction pipeline and the pipeline connecting the system are worn through, scratched or corroded, causing air to enter. The structure of the hydraulic system shall be reasonably designed to rationalize the pipeline layout; Keep the pipeline clean to reduce external corrosion.
(3)加油时由于不注意而产生的气泡被带入油箱内并混入系统中。油箱中应设置专用元器件,减少系统气泡的生成。在回油管与液压泵吸油口之间应设置隔板,在吸油管上方设置一个气泡分离网,就可以分离大约90%的气泡。
(3) Bubbles generated due to carelessness during refueling are brought into the oil tank and mixed into the system. Special components shall be set in the oil tank to reduce the generation of system bubbles. A partition shall be set between the oil return pipe and the oil suction port of the hydraulic pump, and a bubble separation net shall be set above the oil suction pipe to separate about 90% of the bubbles.
