来源:/ 日期:2022-07-04
装载机是施工过程中不可缺少的一个设备,所以平常要好好维护它,防止出现问题而造成隐患,那么我们在这里了解下一个问题--装载机气缸套拉伤以及磨损的原因措施。
The loader is an indispensable equipment in the construction process, so it should be well maintained to prevent problems from causing hidden dangers. Here we learn about the next problem -- the causes and measures of the tension and wear of the loader cylinder liner.
装载机缸套应变
Loader cylinder liner strain
缸套应变的主要表现是:缸内活塞发出敲击声;柴油机功率下降;油燃烧,尾气呈蓝色或白色;油变稀,压力下降。
The main manifestations of cylinder liner strain are: the piston in the cylinder makes a knocking sound; Diesel engine power decreases; When the oil burns, the tail gas is blue or white; The oil becomes thinner and the pressure drops.
(1)气缸故障的原因有:
(1) The causes of cylinder failure are:
①冷却系统故障,机器过热,活塞受热膨胀过大;
① The cooling system is faulty, the machine is overheated, and the piston is heated and expanded too much;
②机油量不足、变质或含有杂质,造成润滑不良;
② Insufficient oil, deterioration or impurities, resulting in poor lubrication;
③活塞与缸壁间隙过小(多见于新机或刚大修的柴油机)
③ The clearance between piston and cylinder wall is too small (mostly seen in new engines or diesel engines that have just been overhauled)
④活塞环断裂或卡住;
④ The piston ring is broken or stuck;
⑤活塞销弹性挡圈失效,导致活塞销移动。
⑤ The piston pin circlip fails, causing the piston pin to move.
装载机缸套磨损
Wear of loader cylinder liner
为减少缸套磨损,除在设计制造上采取防腐耐磨措施外,在使用和维护工程中还应注意以下几点:
In order to reduce the wear of cylinder liner, in addition to taking anti-corrosion and wear-resistant measures in design and manufacture, the following points should also be paid attention to in use and maintenance engineering:
⑴正确启动和启动。
(1) correct startup and startup.
冷车启动后,应在小油门状态下暖车3~5分钟,方可启动自行车。
After the cold start, the bike should be warmed up for 3 ~ 5 minutes under the condition of low throttle before starting.
带负荷工作一段时间,待温度升高后再进行重负荷工作。
Work under load for a period of time, and then work under heavy load after the temperature rises.
(2)保持发动机的正常温度。
(2) Maintain the normal temperature of the engine.
柴油机温度过低,不能保持良好的润滑,会增加气缸壁的摩擦力;温度过高会降低气缸的强度,加剧磨损。为80℃~90℃。当温度超过95℃时,应减少负载或停机冷却。
The temperature of the diesel engine is too low to maintain good lubrication, which will increase the friction of the cylinder wall; Too high temperature will reduce the strength of the cylinder and intensify wear. 80 ℃ ~ 90 ℃. When the temperature exceeds 95 ℃, reduce the load or shut down for cooling.
⑶保持良好的润滑。
(3) keep good lubrication.
定期检查并保持油品质量好,油位适中,并根据季节定期更换。使用粘度适当的油,以确保良好的润滑。
Regularly check and keep the oil quality good and the oil level moderate, and replace it regularly according to the season. Use oil with proper viscosity to ensure good lubrication.
⑷加强三滤(空滤、机油滤、柴油滤)的保养。
(4) strengthen the maintenance of three filters (air filter, oil filter and diesel filter).
这是防止机械杂质进入汽缸,减少汽缸壁磨损,延长发动机使用寿命的主要措施,这对装载机上使用的柴油机来说尤其重要,因为装载机的含尘量往往很高。
This is the main measure to prevent mechanical impurities from entering the cylinder, reduce cylinder wall wear and prolong the service life of the engine, which is particularly important for the diesel engine used on the loader, because the dust content of the loader is often very high.
⑸提高维修保养质量。
(5) improve the quality of maintenance.
济南装载机租赁人员提醒您要严格按照柴油机操作和保养手册规定的技术标准进行保养和维修作业。调整和控制各配合间隙(开启间隙),防止因维修保养不当导致活塞与缸壁加速磨损。
Jinan loader leasing personnel remind you to carry out maintenance and repair operations in strict accordance with the technical standards specified in the diesel engine operation and maintenance manual. Adjust and control the fitting clearance (opening clearance) to prevent accelerated wear of piston and cylinder wall due to improper maintenance.
