Question

本文分析了常用工程机械液压系统维护不当而对其造成的危害，探讨了如何适当维护液压系统。

就液压传动的工程机械而言，液压系统的正常运行是其良好技术状况的一个主要标志。合格的液压油是液压系统可靠运行的保障，正确的维护是液压系统可靠运行的根本。为此，本人根据工作实践，就一般作业环境中工程机械液压系统的维护作一粗略的探讨。

1选择适合的液压油
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。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。
5.31000h检查保养
清洗滤清器，更换滤芯，清洗液压油箱，更换液压油。长期高温作业换油时间要适当提前。当然，如能通过油质检测分析来指导换油是最经济的，

但要注意延长使用的油，每隔100h应检测一次，以便及时发现并更换变质油。
5.47000h和10000h检查维护
液压系统需由专业人员检测，进行必要的调整和维修。根据实践，进口液压泵、液压马达工作10000h后必须大修，否则液压泵、马达因失修可能损坏，对液压系统是至命性的破坏。

Answer 1

This paper analyzes the commonly used construction machinery hydraulic system caused by improper maintenance of the hazards, proper maintenance of the hydraulic system.

On hydraulic engineering machinery is concerned, the normal operation of the hydraulic system is a good technical condition of one of the main signs. Hydraulic oil is a qualified and reliable operation of the hydraulic system of protection, the right to maintain reliable operation of the hydraulic system is fundamental. To this end, I practice, the general operating environment on the hydraulic system of construction machinery in the maintenance of a rough.

1 Select a suitable hydraulic oil
Hydraulic oil in hydraulic system pressure plays a pass, lubrication, cooling, sealing the role of hydraulic oil is not appropriate to select the hydraulic system failure and the durability of early drop. Should be random, "Manual" in the provisions of the brand choice of hydraulic oil, on behalf of special circumstances need to use oil, we should seek its performance and the performance of the same as the original brand. Different grade mix of hydraulic oil, hydraulic oil to prevent chemical reaction, change in performance. Dark brown, white, and the hydraulic oil is the smell of oil deterioration, can not be used.
5.31000h inspection and maintenance
Filter cleaning and replacement of filters, hydraulic oil tank cleaning and replacement of hydraulic oil. Long-term high-temperature oil-operation ahead of time should be appropriate. Of course, such as oil quality through analysis to guide the oil is the most economic,

However, attention should be paid to extend the use of oil, should be detected every time 100h in order to detect and replace the oil deterioration.
10000h inspection and maintenance 5.47000h
Hydraulic system to be detected by the professionals, to make the necessary adjustments and maintenance. According to practice, imports of hydraulic pumps, hydraulic motors to be overhauled after 10000h work, or hydraulic pumps, motors may be damaged due to lack of maintenance on the hydraulic system is the destruction of life

Answer 2

In this paper the commonly used mechanical and hydraulic system for the maintenance of undeserved cause harm, the paper discusses how to properly maintained hydraulic system.

The mechanical engineering hydraulics is concerned, the normal operation of the hydraulic system is one of the main technical conditions. The hydraulic oil is qualified to ensure reliable operation of the hydraulic system, correct and reliable operation of the hydraulic system maintenance is the fundamental. Therefore, I generally work practice, according to the working environment of the hydraulic system of engineering machinery maintenance a rough.

1 choice for the hydraulic oil
The hydraulic oil in hydraulic system plays a relay pressure, lubrication and cooling, sealing, hydraulic oil is not appropriate selection of hydraulic system failure and the durability of the early decline. According to the instructions of random selection of brand stipulated in the hydraulic oil, special circumstances to use for fuel, should strive to its performance with the same grade performance. Different type of hydraulic oil mixed use, can prevent the hydraulic oil chemistry, performance change. Brown, ivory, smell of hydraulic oil is metamorphic oil, cannot use.
5.31000 h examination maintenance
Cleaning, cleaning cartridge filter, replace hydraulic pressure tank, replace hydraulic oil. Long time to replace the oil temperature homework properly in advance. Of course, if can be analyzed by oil testing to guide in oil is the most economic,

But want to notice extended use of oil, should be inspected once every 100h, in order to find out and replace metamorphic oil.
5.47000 h and 10000h examination maintenance
Hydraulic system by professionals, to make necessary adjustment and maintenance. According to the practice of imported hydraulic pump and hydraulic pressure motor, 10000h after work, or to overhaul repair for pump and motor can damage, for hydraulic system of life is to destroy.
