Roller diesel engine assembly accessories are widely used in various types of road roller equipment. In order to ensure the normal operation and extend the service life of the road roller, the maintenance of these accessories is crucial. This article will introduce in detail the structure, common faults, repair and maintenance methods and parts replacement of the diesel engine assembly.
1. Diesel engine assembly structure
The diesel engine assembly is mainly composed of cylinder block, crankcase, cylinder head, fuel system, lubrication system, cooling system and other parts. The cylinder block is the foundation of the engine, carrying moving parts such as pistons, connecting rods, and crankshafts; the crankcase is responsible for collecting and circulating lubricating oil to ensure the lubrication of various internal components of the engine; the cylinder head is responsible for closing the upper part of the cylinder and forming a connection with the top of the piston The combustion chamber completes the combustion process of fuel. The fuel system injects fuel into the combustion chamber through the injector, mixes it with air and then burns to generate power; the lubrication system sends lubricating oil to various components through the oil pump to reduce wear; the cooling system circulates coolant to reduce the engine temperature and prevent overheat.
2. Common faults and causes
1. Difficulty starting the engine: It may be caused by insufficient fuel supply, ignition system failure, blockage of the intake and exhaust systems, etc.
2. Insufficient engine power: It may be caused by malfunction or poor adjustment of the fuel system, ignition system, intake and exhaust system, turbocharger and other components.
3. Engine overheating: It may be caused by poor coolant circulation, water pump failure, clogged radiator, etc.
4. Abnormal engine noise: It may be caused by wear, looseness, breakage of internal moving parts, etc.
3. Repair and maintenance methods
1. Regularly check the oil level and quality to ensure good lubrication.
2. Replace the air filter element regularly to prevent dust and impurities from entering the engine.
3. Regularly check the working condition of the fuel system and ignition system to ensure adequate fuel supply and normal ignition.
4. Regularly check the intake and exhaust systems, clean out carbon deposits and debris, and keep them smooth.
5. Check the working condition of the turbocharger regularly to ensure its normal operation.
6. Regularly check the coolant circulation, clean the radiator and water pump, and ensure that the engine temperature is normal.
4. Parts replacement
During the maintenance process, if the accessories are found to be damaged or severely worn, they need to be replaced in time. Common accessories that need to be replaced include oil filters, air filter elements, fuel filters, fuel injectors, spark plugs, piston rings, crankcase breathers, turbochargers, etc. When replacing parts, you should choose formal channels to purchase original Caterpillar parts to ensure the quality and performance of the parts. At the same time, when replacing accessories, operating procedures should be strictly followed to ensure the safety and accuracy of the replacement process.
In short, the maintenance of the diesel engine assembly of the road roller is the key to ensuring the normal operation of the road roller and extending its service life. By understanding the structure of the engine, common faults and causes, maintenance methods and replacement of accessories, we can better maintain and maintain the Carter roller and improve the stability and reliability of the equipment. At the same time, we should also pay attention to the daily maintenance and upkeep of the equipment, discover and solve problems in time, and ensure the normal operation and production efficiency of the equipment.
