重负荷柴油机油选择标准

来源:https://www.smxnykj.com/ 发布时间:日期:2022-09-27
工程机械设备种类众多,其主要产品为:装载机、挖掘机、叉车、起重机、压路机、混凝土搅拌车、推土机、平地机、摊铺机、盾构机等。
There are many kinds of construction machinery and equipment, and its main products are: loaders, excavators, forklifts, cranes, rollers, concrete mixers, bulldozers, graders, pavers, shield machines, etc.
其中,装载机、挖掘机和叉车3个品种的年产量和保有量占据80%以上市场份额,用油量同样占80%以上。
Among them, the annual output and inventory of loader, excavator and forklift account for more than 80% of the market share, and the oil consumption also accounts for more than 80%.
工程机械设备用油部位主要包括发动机及冷却系统、传动系统、制动系统和一些需脂部件。不同的工程机械设备,用油既有共通之处,也有各自的特点。
Oil parts of construction machinery equipment mainly include engine and cooling system, transmission system, braking system and some grease parts. Different engineering machinery and equipment use oil in common, but also have their own characteristics.
发动机及发动机油
Engine and engine oil
目前工程机械主要以柴油机为动力为主,天然气发动机在徐工、福田雷沃等装载机上也有少量使用。柴油机总体构造包括曲柄连杆和配气两大机构以及燃料供给、润滑、冷却、进排气、启动和电源等五大系统,在高速高负荷工作条件下,各摩擦表面如气缸壁与活塞环、曲轴颈与轴承、凸轮轴与轴承等得到良好的润滑。
At present, construction machinery is mainly driven by diesel engines, and natural gas engines are also used in a small amount on XCMG, Foton Lovol and other loaders. The overall structure of the diesel engine includes two mechanisms: crank connecting rod and valve train, as well as five systems: fuel supply, lubrication, cooling, intake and exhaust, starting and power supply. Under high-speed and high load working conditions, all friction surfaces, such as cylinder wall and piston ring, crankshaft journal and bearing, camshaft and bearing, are well lubricated.
润滑系统的作用就是向各运动零件的摩擦表面输送润滑油,以实现润滑、密封、清洁、冷却、液压、缓冲和防锈等作用。
The function of the lubrication system is to deliver lubricating oil to the friction surfaces of moving parts to achieve the functions of lubrication, sealing, cleaning, cooling, hydraulic pressure, buffering and rust prevention.
柴油机油质量级别的选择
Selection of Diesel Engine Oil Quality Grade
柴油机油质量级别的选择应根据内燃机制造商的推荐、柴油机的机械负荷和热负荷、工作条件的苛刻程度、燃料性能等多种因素确定。
The quality level of diesel engine oil shall be selected according to the recommendation of the internal combustion engine manufacturer, the mechanical load and thermal load of the diesel engine, the severity of working conditions, fuel performance and other factors.
柴油机油黏度级别的选择
Selection of viscosity grade of diesel engine oil
柴油机油黏度级别的选择的主要依据包括:
The main basis for selecting viscosity grade of diesel engine oil includes:
发动机本身设计要求:依据工程机械用发动机设计一般选用。
Engine design requirements: generally selected according to the engine design for construction machinery.
环境温度:若常处于高温环境下,应选高黏度油品,如15W-40甚至20W-50,如果是北方冬季使用,应选低温性能更好的油品。
Ambient temperature: high viscosity oil products, such as 15W-40 or even 20W-50, should be selected if it is often in a high temperature environment. If it is used in northern winter, oil products with better low-temperature performance should be selected.
负荷:大吨位、重负荷、连续高速运转的工程机械,应选用高黏度油,从而保证高温时提供足够的油膜强度;负荷较小、工况缓和的小型机械设备,可使用较低黏度牌号的柴油机油。
Load: For construction machinery with large tonnage, heavy load and continuous high-speed operation, high viscosity oil shall be selected to ensure sufficient oil film strength at high temperature; For small mechanical equipment with small load and moderate working condition, diesel engine oil with lower viscosity can be used.
设备新旧:新设备各方面配合间隙小,可选用低黏度油。旧设备有一定程度的磨损,配合间隙大,需要使用更大黏度的油品才能够达到更好的密封要求,所以旧设备一般用油黏度更高。
New and old equipment: the new equipment has small fitting clearance in all aspects, and low viscosity oil can be selected. The old equipment is worn to a certain extent, and the fit clearance is large, so the oil with higher viscosity is required to meet the better sealing requirements, so the oil viscosity of the old equipment is generally higher.
