挖掘机的液压油起润滑缓冲的作用,需要定期过滤油液、严格按照其使用期限进行保养维护 ,油液的使用寿命或更换周期取决于很多因素,其中包括设备的环境条件与维修保养、液压系统油液的过滤精度和允许污染等级等因素。由于油液使用时间过长,油、水、灰尘、金属磨损物等会使油液变成含有多种污染物的混合液,若不及时更换,将会影响系统正常工作,并导致事故。
The hydraulic oil of excavator plays the role of lubrication and buffering. It needs to filter the oil regularly and maintain it strictly according to its service life. The service life or replacement cycle of the oil depends on many factors, including the environmental conditions and maintenance of the equipment, the filtering accuracy of the hydraulic system oil and the allowable pollution level. Because the oil is used for a long time, the oil, water, dust and metal abrasives will change the oil into a mixture containing various pollutants. If the oil is not replaced in time, it will affect the normal operation of the system and cause accidents.
过滤是控制油液污染的重要手段,是一种强迫滤去油中杂质颗粒的方法。油液经过多次强迫过滤,能使杂质颗粒控制在要求的等级范围内,所以对各类液压设备需制定出强迫过滤油液的精度,以确保油液的清洁度。
Filtration is an important means to control oil pollution, which is a method of forced filtration of impurities in oil. After several times of forced filtration, the impurity particles can be controlled within the required level range. Therefore, the accuracy of forced filtering oil for various hydraulic equipment should be formulated to ensure the cleanliness of the oil.

是否换油取决于油液被污染的程度,目前有3种确定换油期的方法:
Whether to change the oil depends on the degree of oil contamination. There are three methods to determine the oil change period at present
(1)目测换油法。它是凭维修人员的经验,根据目测到的一些油液常规状态变化(如油液变黑、发臭、变成乳白色等),决定是否换油。
(1) Visual inspection of oil change method. It is based on the experience of the maintenance personnel, according to the visual observation of some oil routine state changes (such as the oil turns black, smelly, milky white, etc.), decide whether to change the oil.
(2)定期换油法。根据设备所在场地的环境条件、工作条件和所用油品的换油周期,到期就进行更换。这种方法对液压设备较多的企业很适用。
(2) Regular oil change method. According to the environmental conditions and working conditions of the site where the equipment is located and the oil change cycle of the oil used, it shall be replaced when it is due. This method is suitable for enterprises with more hydraulic equipment.
(3)取样化验法。定期对油液进行取样化验,测定必要的项目(如黏度、酸值、水分、颗粒大小和含量以及腐蚀等)和指标,按油质的实际测量值与规定的油液劣化标准进行对比,确定油液该不该换。取样时间:对一般工程机械的液压系统应在换油周期前一周进行,关键设备(如TBM全断面掘进机等)的液压系统应每隔500小时进行一次取样化验,化验结果应填入设备技术档案。取样化验法适用于关键设备和大型液压设备。
(3) Sampling test method. Regularly sample and test the oil, determine the necessary items (such as viscosity, acid value, moisture, particle size and content, corrosion, etc.) and indicators, and determine whether the oil should be replaced by comparing the actual measured value of oil quality with the specified oil deterioration standard. Sampling time: the hydraulic system of general construction machinery should be conducted one week before the oil change cycle. The hydraulic system of key equipment (such as TBM full face roadheader, etc.) should be sampled and tested every 500 hours. The test results should be filled in the equipment technical files. Sampling test method is suitable for key equipment and large hydraulic equipment.
换油时,要注意清洁,防止赃物侵入液压系统,不可混用和换错,主要有下列要求:
When changing oil, attention should be paid to cleaning to prevent the stolen goods from invading the hydraulic system. It is not allowed to mix and change the oil. The main requirements are as follows:
更换的新油或补加的新油必须是本系统所规定使用的油,经过化验确认其油质已达到规定的性能指标,才能加入。
The new oil to be replaced or added must be the oil specified in the system, and it can be added only after the oil quality has reached the specified performance index through laboratory test.
为保持新油的清洁,换油时要将油箱内部及主要管道内旧油放尽,并把油箱、过滤网、软管清洗干净。加油时油液必须经过过滤,对已疲劳损坏的滤网应更换。
In order to keep the new oil clean, the old oil inside the oil tank and the main pipes should be drained when changing the oil, and the oil tank, filter screen and hose should be cleaned. When refueling, the oil must be filtered, and the filter screen damaged by fatigue should be replaced.
