液压油箱清洁度的研究一.docVIP

摘要 液压系统污染是液压故障的一个主要原因，污染物混入系统后会加速液压元件的磨损、烧伤甚至破坏或引起阀的动作失灵或噪声。还可能引起滤网堵塞，液压泵吸油困难，回油不畅而产生气蚀、振动等。堵塞严重时会因阻力过大而将滤网击穿，完全丧失过滤作用，造成液压系统的恶性循环。通过改进油箱结构，方便焊接操作：通过细化焊接工艺，进一步明确了应焊接焊缝及焊接规范：开发新的油箱前处理、烘干及无尘装配方法，并采取整车试车后液压油过滤方法。所建立的方法与装置可有效避免固体颗粒对液压系统使用寿命的不良影响，达到提高液压油箱清洁度的目的。 　　元件清洗和系统冲洗的目的就是消除或最大限度地减少设备的早期故障。冲洗的目标是提高油液的清洁度,使系统油液的清洁度保持在系统内关键液压元件的污染耐受度内，以保证液压系统的工作可靠性和元件的使用寿命ABSTRACT Hydraulic system hydraulic failure of pollution is a major cause of pollution will accelerate the mixed system the wear of hydraulic components and strict loss, burns and even damage or failure caused by valve movement or noise. May also cause filter plugging, oil pump problems arising from poor oil return cavitation and vibration. Severe congestion due to the resistance is too large to filter breakdown, complete loss of filtration, the hydraulic system caused a vicious cycle. Through improved fuel tank structure, easy welding operations. by refining the welding process, welding seam should be further clarified and welding specifications: the development of new pre-treatment tank, drying and clean assembly methods, and to take the vehicle after the hydraulic oil filter test methods. The method and device can effectively avoid the service life of solid particles on the adverse effects of the hydraulic system, to improve the cleanliness of the purpose of the hydraulic tank.  Component the purpose of cleaning and flushing the system is to eliminate or minimize the early equipment failure. The goal is to increase oil rinse cleanliness, allowing the system to maintain cleanliness of the oil hydraulic components in the system the key within the tolerance of pollution, to ensure that the work of the hydraulic system reliability and component life  Key Words: hydraulic system；welding；hydraulic tankcleanliness 提高液压油箱清洁度的研究 摘要 II I
