对机械化施工公司而言,工程机械设备技术性情况的优良是否是公司可否一切正常生产制造的立即要素。就液压传动的工程机械设备来讲,液压传动系统的一切正常运作是其优良技术性情况的1个关键标示。及格的齿轮油是液压传动系统靠谱运作的确保,恰当的维护保养是液压传动系统靠谱运作的本质。依据工作中实践活动,就通常工作 自然环境中工程机械设备液压传动系统的维护保养作一粗略地的讨论。

For the mechanized construction company, whether the technical condition of engineering machinery and equipment is good or not is the immediate factor of whether the company can make all the normal production. As far as the engineering machinery and equipment of hydraulic transmission are concerned, the normal operation of hydraulic transmission system is a key indication of its excellent technical situation. Qualified gear oil ensures the reliable operation of the hydraulic transmission system, and proper maintenance is the essence of the reliable operation of the hydraulic transmission system. According to the practical activities in work, the maintenance of hydraulic transmission system of engineering machinery and equipment in normal working natural environment is discussed roughly.


液压油

Hydraulic oil

齿轮油在液压传动系统中起着传送工作压力、润化、水冷却、密封性的功效,齿轮油挑选不适当是液压传动系统初期常见故障和使用性能降低的关键缘故。应按任意《使用手册》中要求的型号挑选齿轮油,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。不同牌号的液压油不能混合使用,以防液压油产生化学反应、性能发生变化。深褐色、乳白色、有异味的液压油是变质油,不能使用。

Gear oil plays the role of transmitting working pressure, moistening, water cooling and sealing in the hydraulic transmission system. Improper selection of gear oil is the key reason for the common faults in the initial stage of the hydraulic transmission system and the degradation of its service performance. Gear oil should be selected according to the type required in the manual. When the substitute oil is needed in special cases, the performance of the gear oil should be the same as that of the original brand. Hydraulic oils of different grades can not be mixed to prevent chemical reaction and performance change of hydraulic oils. Dark brown, Milky white, odorous hydraulic oil is deteriorated oil, can not be used.


防止固体杂质混入液压系统

Preventing solid impurities from mixing into hydraulic system

清理的齿轮油是液压传动系统的性命。液压传动系统中有很多高精密偶件,有的有减振小圆孔、有的有间隙等。若固态残渣侵入将导致高精密偶件挫伤、开卡、油道阻塞等,严重危害液压传动系统的安全性运作。通常固态残渣侵入液压传动系统的方式有:齿轮油不干净的;给油专用工具不干净的;给油和检修、维护保养不小心;液压件起屑等。能够从下列好多个层面避免固态残渣侵入系统软件:

Cleaning gear oil is the life of hydraulic transmission system. There are many high-precision couples in the hydraulic transmission system, some with small circular holes, some with clearances and so on. If solid residue intrudes, it will lead to contusion of high precision couples, opening of cards, blocking of oil passages, etc., which seriously endangers the safe operation of hydraulic transmission system. Usually solid residue invades the hydraulic transmission system in the following ways: gear oil is not clean; special tools for oil supply are not clean; oil supply and maintenance, maintenance is not careful; scraping of hydraulic parts, etc. It can avoid solid residue intrusion into system software from the following aspects:


加油时

When refueling

齿轮油务必过虑充注,给油专用工具应靠谱清理。不可以以便提升给油速率而除掉汽车油箱给油口处的过滤装置。给油工作人员应应用整洁的胶手套和工作服装,防止固态残渣和化学纤维残渣跌入油中。

Gear oil must be carefully filled, and special tools for oil supply should be cleaned up by spectrum. It is not possible to remove the filter at the feeding port of the automobile fuel tank in order to increase the feeding rate. Oil workers should use neat rubber gloves and work clothing to prevent solid residues and chemical fiber residues from falling into the oil.

保养时拆装液压油箱给油盖、滤芯盖、检验孔、液压油管等位置,导致系统软件油道曝露时要绕开工地扬尘,拆装位置要先完全清理后能够开启。如拆装液压油箱给油盖时,先去除油盖周围的土壤,拧下来油盖后,消除残余 在接合部位的杂物(不能用水冲洗以免水渗入油箱),确认清洁后才能打开油箱盖。如需使用擦拭材料和铁锤时,应选择不掉纤维杂质的擦拭材料和击打面附着橡胶的专用铁锤。液压元件、液压胶管要认真清洗,用高压风吹干后组装。选用包装完好的正品滤芯(内包装损坏,虽然滤芯完好,也可能不洁)。换油时同时清洗滤清器,安装滤芯前应用擦拭材料认真清洁滤清器壳内底部污物。

During maintenance, the position of hydraulic tank feeding cap, filter cap, inspection hole and hydraulic oil pipe should be disassembled and assembled, which will lead to the system software oil duct to be exposed around the site dust, and the disassembly position should be cleaned completely before it can be opened. For example, when disassembling and assembling the hydraulic oil tank to the oil cap, first remove the soil around the oil cap, after screwing off the oil cap, remove the remaining debris in the joint position (can not be washed with water to avoid water infiltration into the oil tank), confirm that the oil tank cap can be opened after cleaning. When wiping materials and hammers are needed, special wiping materials and hammers that do not remove impurities from fibers should be selected. Hydraulic components and hydraulic rubber pipes shall be cleaned carefully and assembled after being dried by high-pressure air. Choose the well-packed filter element (the inner packaging is damaged, although the filter element is intact, it may also be unclean). When changing oil, clean the filter at the same time. Before installing the filter element, carefully clean the dirt at the bottom of the filter housing with wiping materials.


液压系统的清洗

Cleaning of Hydraulic System

清理油务必应用与系统软件常用型号同样的齿轮油,油温度在45~80℃中间,用大总流量尽量将系统软件中残渣带去。液压传动系统要不断清理多次左右,每一次清理完后,趁油热时将其全部放出系统。清洗完毕再清洗滤清器、更换新滤芯后加注新油。

Cleaning oil must be applied with gear oil of the same type as commonly used in system software. The oil temperature is between 45 ~80 C, and the residue in system software should be removed as far as possible with large total flow rate. Hydraulic transmission system should be cleaned up many times or so, after each cleanup, when the oil is hot, all of them are released from the system. After cleaning, clean the filter, replace the filter element and fill in new oil.


防止空气入侵液压系统

Prevent air intrusion into hydraulic system

在常压常温下液压油中含有容积比为6~8%的空气,当压力降低时空气会从油中游离出来,气泡破裂使液压元件气蚀,产生噪声。大量的空气进入油中将使气蚀现象加剧,液压油压缩性增大,工作不稳定,降低工作效率,执行元件出现工作爬行等不良后果。另外,空气还会使液压油氧化,加速油的变质。防止空气入侵应注意以下几点:

Hydraulic oil contains air with a volume ratio of 6 to 8% at normal pressure and temperature. When pressure decreases, air will be free from the oil. Bubble breakdown causes cavitation of hydraulic components and produces noise. A large amount of air entering into the oil will aggravate the cavitation phenomenon, increase the compressibility of hydraulic oil, work instability, reduce work efficiency, and have adverse consequences such as working crawl of the executive components. In addition, air can also oxidize the hydraulic oil and accelerate the deterioration of the oil. To prevent air intrusion, the following points should be paid attention to:


1、维修和换油后要按随机《使用说明书》规定排除系统中的空气,才能正常作业。

1. After repairing and changing oil, the air in the system should be excluded according to the stipulation of the random "instruction book", so as to work normally.

2、液压油泵的吸油管口不得露出油面,吸油管路必须密封良好。

2. The nozzle of the suction pipe of the hydraulic oil pump shall not be exposed to the oil surface, and the suction pipe shall be well sealed.

3、油泵驱动轴的密封应良好,要注意更换该处油封时应使用双唇正品油封,不能用单唇油封代替,因为单唇油封只能单向封油,不具备封气的功能。本单位曾有一台柳工ZL50装载机大修后,液压油泵出现连续气蚀噪声、油箱油位自动升高等故障,经查询液压油泵修理过程,发

3. The seal of the driving shaft of the oil pump should be good, and attention should be paid to the use of genuine lip oil seals when replacing the oil seals at this place. It can not be replaced by single lip oil seals, because single lip oil seals can only seal oil unilaterally and do not have the function of sealing gas. After the overhaul of a Liugong ZL50 loader, the hydraulic oil pump suffered from continuous cavitation noise, and the oil level of the oil tank rose automatically. After inquiring about the repair process of the hydraulic oil pump, the author issued a report.


防止水入侵液压系统

Preventing Water Invasion into Hydraulic System

油中含有过量水分,会使液压元件锈蚀、油液乳化变质、润滑油膜强度降低,加速机械磨损.除了维修保养时要防止水分入侵外,还要注意储油桶不用时,要拧紧盖子,最好倒置放置;含水量大的油要经多次过滤,每过滤一次要更换一次烘干的滤纸,在没有专用仪器检测时,可将油滴到烧热的铁板上,没有蒸气冒出并立即燃烧方能加注。

Excessive moisture in oil will make hydraulic components rust, oil emulsification deterioration, lubricant film strength decrease, and accelerate mechanical wear. In addition to preventing moisture intrusion during maintenance, attention should also be paid to tightening the cover when oil storage barrel is not in use, and it is best to put it upside down. Oil with large moisture content should be filtered many times, and drying filter paper should be replaced once for each filtration, without special instruments for inspection. In time measurement, oil droplets can be placed on the hot iron plate, without steam coming out and burning immediately before filling.


机械作业要柔和平顺

Machinery operation should be gentle and smooth

机械作业应避免粗暴,否则必然产生冲击负荷,使机械故障频发,大大缩短使用寿命。作业时产生的冲击负荷,一方面使机械结构件

Machinery operation should avoid roughness, otherwise it will inevitably produce impact load, which will cause frequent mechanical failures and greatly shorten the service life. On the one hand, the impact load produced during operation makes the mechanical structure part
