挖掘机的加长臂如何保养?小编就给大家讲解一下吧!
How to maintain the lengthening arm of excavator? Xiaobian will explain it to you!
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. Replace the fuel filter element and additional fuel filter element after the new machine works for 250h; Check the engine valve clearance.
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 the air filter element; Clean the inside of the cooling system; Check and tighten the track shoe bolts; Check and appropriately adjust the reverse tension of the track; Check the air inlet heater; Replace the bucket teeth; Adjust bucket clearance; Check the liquid level of front window cleaning fluid; Check and adjust the air conditioner; Clean the floor in the cab; Replace the crusher filter element (optional). When cleaning the inside of the cooling system, after the engine is fully cooled, slowly loosen the water injection port cover to release the internal pressure of the water tank, and then drain the water; Do not clean the engine when it is working. The high-speed rotating fan will cause danger; When the coolant is replaced on the ground, the machine should be kept on the ground; Replace the coolant and anti-corrosion device according to table 3. The proportion of antifreeze and water shall be added.
3、由于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。
3. Since the lengthening arm of the excavator is longer, heavier and has greater action inertia than the standard arm, it is lighter than the standard arm during operation. Each operation process should be stable, and the action should not be too fast or too fierce. It is not suitable for emergency braking. The capacity of the bucket should be configured according to the factory standard. It is strictly prohibited to replace the bucket with a large capacity.
特别注意的配件保养:
Special attention to 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 the friction coefficient in the movement process and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, they have larger radial size, vibration and noise, and higher price.
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: a bearing that works under sliding friction. The sliding bearing works stably, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by the lubricating oil without direct contact, which can also greatly reduce the friction loss and surface wear. The oil film also has the ability of vibration absorption, but the starting friction resistance is large
