保养挖掘机加长臂的经验分享

1、新机工作250h后就应更换燃油滤芯和附加燃油滤芯;检查发动机气门的空隙。
1. The fuel filter element and additional fuel filter element should be replaced after 250 hours of operation, and the air gap of engine valve should be checked.
2、日常保养;检查、洗涤或变换空气滤芯;冷却系统内部进行清洗;检查并拧紧履带板螺栓;检查并适度调节履带反张紧度;检查进气加热器;更换斗齿;调节铲斗间隙;检查前窗清洗液液面;检查、调节空调;清洗驾驶室内地板;更换破碎器滤芯(选配件)。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,释放水箱内部压力,然后才能放水;不要在发动机工作时进行清洗工作,高速旋转的风扇会造成危险;当清洁或更换冷却液时,应将机器停放在水平地面上;要按照表3更换冷却液和防腐蚀器。防冻液与水的比例要求添加。
2. Daily Maintenance; Check, Wash or Change Air Filter; Clean the cooling system; Check and tighten the crawler bolts; Check and moderately adjust the back tension of the crawler; Check the intake heater; Change the bucket teeth; Adjust the clearance of the bucket; Check the liquid level of the front window; Check and adjust the air conditioning; Clean the cab. Flooring; replace the filter cartridge (selections). When cleaning the inside of the cooling system, slowly loosen the cover of the water injection nozzle after the engine has cooled sufficiently to release the internal pressure of the water tank before releasing water. Replace coolant and corrosion inhibitor according to table 3. The proportion of antifreeze and water is required to be added.
3、由于山东挖掘机加长臂比标准臂更长、更重、动作惯性更大,因此,操作时比标准臂要轻,各操纵过程应平稳,动作不宜过快、过猛,不宜紧急制动

3. Because the lengthened arm of Shandong excavator is longer, heavier and more inertia than the standard arm, it is lighter than the standard arm in operation, and the operation process should be stable, and the action should not be too fast and violent, so it is not suitable for emergency braking.
挖斗容量按出厂标准配置使用,严禁更换使用大容量的挖斗。
The excavator capacity is used according to the factory standard, and it is strictly prohibited to replace the bucket with large capacity.
特别注意的配件保养:
Special attention to accessories 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摩擦系数,并保证其回转精度。按运动元件摩擦性质的不同,轴承可分为滚动轴承和滑动轴承两大类。其中滚动轴承已经标准化、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 its friction coefficient in the process of motion, and ensure its rotary accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is higher.
滑动轴承:在滑动摩擦下工作的轴承。滑动轴承工作平稳、可靠、无噪声。在液体润滑条件下,滑动表面被润滑油分开而不发生直接接触,还可以大大减小摩擦损失和表面磨损,油膜还具有吸振能力,但起动摩擦阻力较大。
Sliding bearing: Bearing under sliding friction. Sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and the friction loss and surface wear can be greatly reduced. The oil film also has the ability of absorbing vibration, but the starting friction resistance is large.
滚动轴承是将运转的轴与轴座之间的滑动摩擦变为滚动摩擦,从而减少摩擦损失的一种精密的机械元件。滚动轴承一般由内圈、外圈、滚动体和保持架四部分组成。
Rolling bearing is a kind of precise mechanical element which changes the sliding friction between the running shaft and the shaft seat into rolling friction and reduces the friction loss. Rolling bearings are generally made up of four parts: inner ring, outer ring, rolling element and cage.
挖掘机的作业和行走场地应平整坚实,对松软地面应垫以枕木或垫板,沼泽地区应先作路基处理,或更换湿地专用履带板。
The working and walking grounds of excavators should be smooth and solid, and the soft ground should be padded with sleepers or pads. In swamp areas, the roadbed should be treated first, or the special Caterpillar board for wetland should be replaced.
