I. The design of the product

Corps: it is made of high -strength carbon steel with special anti -corrosion treatment, which has good corrosion and abrasive resistance and can be used for a long time in severe operating conditions. The thickness of the case is usually 3 - 5 mm, which provides the structural strength of the muffler and prevents its deformation or damage when exposed to external forces.

Internal structure: Inside, multilayer soundproofing materials and sound -absorbing structure, ordinary sound -absorbing wool, perforated slabs and so on are used. Sound -absorbing cotton is usually made of fiberglass or ceramic fiber, which has good sound -absorbing properties and can effectively reduce the noise of the exhaust. The perforated plate is evenly distributed with small holes, which further reduces noise due to changing the direction and velocity of the exhaust air flow. These materials and designs work in combination with each other, forming an effective noise reduction system.

Connecting parts: besieged by special connecting flanges, bolts and gaskets, the compounds are strong and well tight. The connecting flange is made of the same material as the case, and is subjected to accurate processing to ensure perfect combination with the exhaust system of the excavator. The sealing gasket is made of rubber resistant to high temperatures and aging, which prevents the leakage of exhaust gases and provides the jamming effect.

Secondly, operational characteristics

A highly effective decrease in noise: due to the optimization of the internal structure and the choice of high-quality sound-absorbing materials, the muffler can effectively reduce the noise of the exhaust gases of the excavator engine, which in general can reduce the noise by 20-30 decibels, providing a relatively calm working environment for operators, and at the same time, and at the same time, and at the same time Reducing noise pollution of the environment.

High thermal resistance: the silencer must withstand the effects of high -temperature exhaust gases in the process, therefore, it uses high -temperature materials and structural design. It can work normally at a temperature of exhaust gases up to 500 - 800 ℃, and will not be deformed, damaged or reduced the productivity of the silencer due to high temperature.

Strength: the general structure is reliable and durable, after strict quality testing and strength tests, it can adapt to the frequent launch, stop and difficult conditions of the excavator. With normal use and maintenance, the service life can reach 3-5 years, which reduces the frequency of replacement and reduces the cost of equipment service.

Good adaptability: specially designed for various models of Sany excavators, it is ideally combined with the exhaust system of the engine, ensuring the convenience of installation and the best jamming effect.

Applicable models

Small excavators: such as SY16C, SY35U and other models, usually used in small urban infrastructure, demolition of buildings, gardening and other works. The silencers of these models have relatively small sizes, but at the same time have effective noise -acting characteristics, which allows you to satisfy the requirements for the fight against noise when working in densely populated areas.

Medium excavators: including SY135C, SY195C, SY215C, SY245C, etc., which are the main models in the construction of buildings, road construction and mining industry. The silencer can effectively cope with a large volume of exhaust gases and high pressure of the exhaust gases of the engine, providing the jamming effect without the effect on the engine power.

Large excavators: models such as SY365C and SY485C are mainly used in large -scale mining and water protection projects. Their silencers are made of more durable materials and have a more complex design, which can withstand higher temperatures and pressure and ensure stable operation in severe operating conditions.

Installation

Preparation: Before installing the silencer, make sure that the excavator is stopped and the engine is in a cold state to avoid burns. Prepare the necessary installation tools, such as wrenches, screwdrivers, jacks, etc. At the same time, make sure that the model of the new silencer corresponds to the excavator model, and its details are complete and are in good condition.

Removing the old silencer: with the help of a wrench, unscrew the bolts connecting the old muffler with the exhaust pipe, trying to save the bolts and gaskets. If there is a welded section between the silencer and the pipe, you will need to use the cutting tool to carefully separate it. In the process of dismantling, try not to damage the surrounding components, such as exhaust pipes and engine. If the muffler is installed low, it may be required to use the jack to raise an excavator for more convenient operation.

Installation of a new muffler: combine the connecting flange of a new muffler with an exhaust pipeline, making sure that the holes in both are exactly the same. Then connect the muffler to the exhaust pipe using bolts and gaskets, gradually tightening the bolts in the diagonal order to provide a strong connection and good seal. Be careful and do not tighten the bolts too much, as this can lead to deformation of the muffler or pipeline. In the process of tightening the bolts, you can use the level to check whether the muffler is installed horizontally, and correct it in time if there are deviations.

Checking and debugging: After the installation is completed, carefully check the muffler installation to make sure that all connecting parts are tightened, and the gasket is not damaged and does not proceed. Run the excavator and let the engine work for a while to check if there is no abnormal vibration, noise or exhaust gases in the muffler. If the problems are found, stop the car in time to check and adjust. In addition, to check the noise level after installing the muffler, you can use the Seekmer to make sure the desired jamming effect.

Maintenance points

Periodic cleaning: through regular time intervals (recommended every 200-300 hours of operation), the muffler should be cleaned with compressed air. Pass the compressed air through the intake or exhaust foramen of the muffler to remove dust, pollution and carbon deposits accumulated inside. If there are oil or other spots on the surface of the muffler, wipe it with a soft cloth with a soft detergent, but be careful so that the detergent does not get into the muffler.

Checking the connecting part: every time the excavator undergoes planned maintenance, check the connecting bolts and laying of the silencer. Check if the bolts are weakened, and if they are weakened, tighten them in a timely manner to provide a strong connection. At the same time, check if there is aging, damage or deformation of the gasket, if it is found that the laying has problems, it should be replaced in a timely manner to prevent the exhaust gases leak affecting the muffler effect.

Concern with the situation with the exhaust: in the process of the excavator, pay attention to whether the exhaust is smooth, is there an abnormal sound of exhaust or smoke. If you find that the exhaust is not even, it can be an internal cloudy of the muffler, which must be checked and cleaned in a timely manner. If the color of the exhaust is abnormal, for example, black smoke, blue smoke, etc., this may mean that the engine is faulty, which will also affect the normal operation of the muffler, and you need to check the problems with the engine in time.

Avoid external exposure: during the operation and parking of the excavator, pay attention to avoiding external impact on the muffler. Because the blow can lead to deformation of the muffler body, damage to the internal structure, which will reduce the efficiency of jamming or even lead to the failure of the muffler. If the muffler accidentally hit, it is necessary to check in a timely manner its appearance and performance, and if it is damaged, then it should be replaced in a timely manner or replaced.

Regular replacement of the wear of the wear parts: sound -absorbing cotton and other parts inside the muffler are the wear of the details, and their sound -absorbing ability is gradually decreasing with an increase in the use of use. It is usually recommended to check and replace sound-absorbing cotton every 1-2 years (or depending on actual use) so that the muffler always retains a good sound-absorbing effect.
