As a heavy mechanical equipment, the noise problem of excavators has always been one of the hot issues in their use compared to other mechanical equipment. Especially if the engine noise of the excavator is too loud, it will not only affect the working efficiency of the excavator, but also disturb the people, and it is also a warning of engine failure.
Reasons:
1.The engine intake pipe is not clean.During the engineering operation of the excavator, the engine intake pipe is often blocked by dust, sand, soil and other impurities. Lead to blocked air flow, increase engine burden, noise and even cause safety risks.
2. Poor sealing of the engine cylinder block or wear of the cylinder liner. In the engine of the excavator, the cylinder block and the cylinder liner are very important parts, which directly affect the operating efficiency and stability of the engine. If the cylinder block is not well sealed or the cylinder liner is worn excessively, it will cause the engine power to drop, the pressure in the cylinder to be too high, and the exhaust noise to increase.
3. When the synchronizer is damaged or the gear gap is too large, the engine will not work smoothly, which will bring many problems to the normal operation of the machine, such as unstable speed and gear meshing noise.
4. The engine oil is insufficient or the oil cleanliness is not high. Engine oil is a vital lubricant that plays an irreplaceable role in the normal operation and maintenance of the engine. If the engine oil is insufficient or the cleanliness is not high, it will cause serious damage and failure to the engine, resulting in reduced lubrication performance and friction noise.
Solutions：
1. Regularly clean the engine intake pipe, choose the right cleaning tools. Usually can use chemical cleaning agents, high-pressure water gun, disassembly cleaning and other methods to clean. It needs to be cleaned about every 500 hours or so to ensure the smooth flow of the engine intake pipe.
2. The reasons for poor cylinder sealing may include cylinder surface wear or deformation, aging or damaged cylinder gaskets, etc. In order to detect and repair these problems, we need to conduct a compression test to determine whether there is a pressure leak problem, and then use a grinder to level the cylinder surface or replace the gasket; cylinder liner wear may be due to long periods of high temperature operation resulting in insufficient lubrication, or impurities into the cause. The best solution at this point is to replace the cylinder liner with a brand new one and reduce the engine overheating as much as possible.
3. The usual solutions to engine synchronizer damage or excessive gear clearance include replacing faulty parts, readjusting gear clearance, and strengthening maintenance and repair measures. It also requires frequent testing and maintenance to ensure the stable operation of engine parts and improve the reliability and safety of the machine.
4. Regularly replace the engine oil and maintain its cleanliness. To ensure the safety and long service life of the engine, it is necessary to always pay attention to the use of oil. During daily use, it is necessary to regularly check the quality and quantity of the oil, maintain its adequacy and cleanliness, and replace it in a timely manner.
Notes:
1. Before any repair and maintenance operations, it is necessary to disconnect the engine power and stop the engine.
2. During operation, it is necessary to prevent liquids such as oil and water from entering the engine interior.
3.When repairing and replacing, it is necessary to check whether the accessories meet the standards to ensure the quality and safety of the work.
