挖掘机该怎么样保养?

日期:2019-02-26   来源:http://www.txkql.com
挖掘机想必我们都不陌生,那么你知道该热河保养挖掘机吗? 不知道的一起跟小编去看看吧!
Excavators must be familiar to all of us, so do you know the Jehol maintenance excavator? I don't know. Let's go with Xiaobian.
1、新机作业250h后就应替换燃油滤芯和附加燃油滤芯;查看发动机气门的空隙。
1. Fuel filter element and additional fuel filter element should be replaced after 250 hours of operation of the new engine, and the clearance of the engine valve should be checked.
2、日常保养;查看、洗涤或改换空气滤芯;冷却系统内部进行清洗;查看并拧紧履带板螺栓;查看并适度调节履带反张紧度;查看进气加热器;替换斗齿;调节铲斗间隙;查看前窗清洗液液面;查看、调节空调;清洗驾驭室内地板;替换破碎器滤芯(选配件)。
2. Daily maintenance; check, wash or change the air filter element; clean the cooling system interior; check and tighten the caterpillar plate bolts; check and moderately adjust the back tension of the caterpillar; check the intake heater; replace bucket teeth; adjust the bucket clearance; check the liquid level of the front window; check and adjust the air conditioning; clean and control the indoor floor; replace the filter element of the crusher (optional accessories).
清洗冷却系统内部时,待发动机充分冷却后,缓慢拧松注水口盖,开释水箱内部压力,然后才干放水;不要在发动机作业时进行清洗作业,高速旋转的风扇会造成风险;当清洁或替换冷却液时,应将机器停放在水平地面上;要按照表3替换冷却液和防腐蚀器。防冻液与水的比例要求增加。
When cleaning the cooling system, after the engine is fully cooled, slowly unscrew the nozzle cover, release the internal pressure of the water tank, and then release the water; do not clean the engine while working, the high-speed rotating fan will cause risks; when cleaning or replacing the coolant, the machine should be parked on the horizontal ground; replace the coolant and corrosion preventer according to Table 3. The ratio of antifreeze to water should be increased.
3、由于挖掘机加长臂比规范臂更长、更重、动作惯性更大,因此,操作时比规范臂要轻,各操作过程应平稳,动作不宜过快、过猛,不宜紧急制动挖斗容量按出厂规范配置运用,严禁替换运用大容量的挖斗。
3. Because the excavator's elongated arm is longer, heavier and more inertial than the standard arm, the operation is lighter than the standard arm. The operation process should be smooth. The action should not be too fast or too violent. The emergency brake bucket capacity should not be allocated according to the factory specifications. It is strictly forbidden to replace the large capacity bucket.
特别注意的配件保养:
Particular attention to spare parts maintenance:
轴承是机械设备中一种重要零部件,它的主要功能是支撑机械旋转体,降低其运动过程中的冲突系数,并保证其反转精度。按运动元件冲突性质的不同,轴承可分为滚动轴承和滑动轴承两大类。其中滚动轴承已经规范化、系列化,但与滑动轴承相比它的径向尺寸、振动和噪声较大,价格也较高。
Bearing is an important part of mechanical equipment, its main function is to support the mechanical rotating body, reduce the conflict coefficient in its movement process, and ensure its inversion accuracy. Bearings can be classified into rolling bearings and sliding bearings according to the conflict nature of moving elements. Rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibration and noise are larger, and their prices are higher.
滑动轴承:在滑动冲突下作业的轴承。滑动轴承作业平稳、牢靠、无噪声。在液体光滑条件下,滑动外表被光滑油分隔而不发生直接接触,还可以大大减小冲突损失和外表磨损,油膜还具有吸振能力,但起动冲突阻力较大。
Sliding Bearing: Bearing operating under sliding conflict. Sliding bearings work smoothly, reliably and noiselessly. Under the condition of smooth liquid, the sliding surface is separated by smooth oil without direct contact, and the loss of conflict and surface wear can be greatly reduced. The oil film also has the ability to absorb vibration, but the starting conflict resistance is larger.
