1、燃油的管理
1, fuel management
要根据不同的环境温度选用不同牌号的柴油;柴油不能混入杂质、灰土与水,否则将使燃油泵过早磨损;劣质燃油中的石蜡与硫的含量高,会对发动机产生损害;每日作业完后燃油箱要加满燃油,防止油箱内壁产生水滴;每日作业前打开燃油箱底的放水阀放水;在发动机燃料用尽或更换滤芯后,须排尽管路中的空气。 最低环境温度 0℃ -10℃ -20℃ -30℃ 柴油牌号 0# -10# -20# -35# . 加长臂挖掘机租赁:www.dyqicheng.com
According to the different environmental temperature with different grades of diesel; diesel oil can not be mixed with impurities, dust and water, otherwise it will make the fuel pump premature wear; content of paraffin and sulfur in the fuel is high, will cause damage to the engine; the daily operation after the fuel tank fuel tank to fill, to prevent the inner wall of the water drain valve; open drain fuel tanks daily before operation; when the engine ran out of fuel or replace the filter, to discharge the air in the pipeline. The lowest ambient temperature of 0 DEG -10 DEG -20 DEG -30 DEG 0# -10# -20# diesel grade -35#.
2、其它用油的管理
2, other oil management
其他用油包括发动机油、液压油、齿轮油等;不同牌号和不同等级的用油不能混且;不同品种挖掘机用油在生产过程中添加的起化学作用或物理作用的添加剂不同;要保证用油清洁,防止杂物(水、粉尘、颗粒等)混入;根据环境温度和用途选用油的标号。环境温度高,应选用粘度大的机油,环境温度低应选用粘度小的用油;齿轮油的粘度相对较大,以适应较大的传动负载,液压油的粘度相对较小,以减少液体流动阻力。
Other oil includes engine oil, hydraulic oil, gear oil and so on; different grades and different grades of oil cannot be mixed and additive; different varieties of excavator oil in the production process to add the chemical or physical interaction is different; to ensure clean oil, to prevent debris (water, dust particles, etc.) into the environment according to the label; the temperature and the use of selected oil. The environment temperature is high, should choose the oil viscosity, low ambient temperature should choose low viscosity gear oil; oil viscosity is relatively large, in order to adapt to the larger transmission load, hydraulic oil viscosity is relatively small, in order to reduce the resistance of liquid flow.
3、润滑油脂管理
3, lubricating oil management
采用润滑油(黄油)可以减少运动表面的磨损,防止出现噪声。润滑脂存放保管时,不能混入灰尘、砂粒、水及其它杂质;推荐选用锂基型润滑脂G2-L1,抗磨性能好,适用重载工况;加注时,要尽量将旧油全部挤出并擦干净,防止沙土粘附。
Used lubricating oil (Huang You) can reduce the surface of sports wear, to prevent noise. Grease storage, can not be mixed with dust, sand, water and other impurities; recommended lithium based grease G2-L1, good abrasion resistance, suitable for heavy load; when filling, to minimize all the old oil extrusion and clean, prevent sand adhesion.
4、滤芯的保养
4, the maintenance of the filter
滤芯起到过滤油路或气路中杂质的作用,阻止其侵入系统内部而造成故障;各种滤芯要按照(操作保养手册)的要求定期更换;更换滤芯时,应检查是否有金属附在旧滤芯上,如发现有金属颗粒奕及时诊断和采取改善措施;使用符合机器规定的纯正滤芯。伪劣滤芯的过滤能力较差,其过滤层的面各人和材料质量都不符合要求,会严重影响机器的正常使用。
The filter to filter impurities in the oil or gas path, prevent its invasion within the system caused by the fault; filter according to the (operating and maintenance manuals) requires regular replacement; replacement of filters, should check whether the metal is attached to the old filter, if found to have metal particles Yi timely diagnosis and improvement measures; comply with the provisions of the use of pure filter machine. Fake filter filtering ability is poor, the quality of the surface of each filter layer and the material does not meet the requirements, will seriously affect the normal use of the machine. 长沙长臂挖掘机出租 www.hnsxwjj.com
