Carbon deposition is a dense carbon oil compound. Since diesel and oil are not completely burned into the cylinder, oil is deposited on the surface of the engine cylinder head, cylinder liner, piston, valve, combustion chamber, fuel injector, etc. Solid phase layered carbon deposition The thermal conductivity is poor. Long-term accumulation can lead to local overheating of the parts. Severe nozzles, valve ablation, piston ring blockage, and cylinder pull can cause serious failures. In addition, if carbon deposits accumulate on the surface of the combustion chamber, it can also cause The increase in compression ratio, pre-combustion, knocking, etc., seriously affects the engine's power and fuel consumption. Therefore, the excavator must regularly check the carbon layer to completely remove the carbon layer for maintenance.

Method 1: The simplest and most direct method of mechanically grinding carbon deposits is mechanical polishing with tools. You can use wire brushes, scrapers, bamboo or abrasive cloth to wipe carbon deposits. Special tools can be used for special shaped parts. Carbon deposition, For example, a thin wire brush can be used to clean the carbon deposit around the nozzle. The pressure chamber is made up of a special needle. The valve rail and seat carbon can be removed with a cylindrical wire brush.

The mechanical grinding method is difficult, but the efficiency is low, the cleaning effect is poor, and many small scratches are left in the cleaning process. The surface smoothness of the parts is large and it is easy to become a new carbon accumulation point.

Method 2: The principle of sandblasting is similar to sandblasting, but the blasting granules are not sand. When spraying the core, high-speed airflow is used to spray the walnut sand to the surface of the parts to remove carbon deposits and oil, and the carbon deposition efficiency is high and clean. This method requires special equipment and is difficult to use widely.

Reasonable Operation Of Track Bulldozer

图片
The  Track Bulldozer   has the greatest influence on the transmission oil temperature due to the external resistance and the maximum output torque during the shovel operation. If the small throttle is used for a long time to operate the torque converter in the inefficient zone, the transmission oil temperature will rise. If the large throttle is used during frequent shifting, it will cause severe impact on the machine and increase the temperature of the transmission oil. To this end, the operator should reasonably control the amount of bulldozer and the timing of the blade lifting and lowering. The soil feeding distance should not be too long, so as to prevent the use of small throttle for a long time. We are  Track Bulldozer Supplier , specializing in the production of machinery and equipment, welcome to consult and order.

  Purchasing a bulldozer is a significant investment, whether you're in the construction business or need one for specific projects. To ensure you make an informed decision and get the   right bulldozer   for your needs, here are four essential tips and things to know before buying one: 1. Define Your Requirements and Applications The first step in   buying a bulldozer  is understanding your specific requirements and applications. Consider the following: Size and Capacity:  Bulldozers come in various sizes and capacities. Determine the size that can handle your typical projects and the type of material you'll be moving. Attachments:  Many bulldozers can be equipped with various attachments, such as blades, rippers, and winches. Assess which attachments you need for your tasks. Terrain:  Consider the type of terrain you'll be working on, as this can affect the tracks or tires your bulldozer should have. Understanding your specific needs will help you narrow down your options

No Steering Failure of Crawler Hydraulic Steering Bulldozer

  During the use of the bulldozer, due to various reasons, the bulldozer is difficult to turn, cannot turn, cold cars can turn, hot cars can not turn. After the occurrence of these failure phenomena, according to the use time of the bulldozer and the occurrence process of the failure, the classification analysis should be carried out to check the truth, which can avoid unnecessary disassembly and reduce the internal pollution of the machine. The following   Bulldozer Suppliers   introduce common fault phenomena such as bulldozers and related knowledge of inspection and elimination. When the  Dozer  is in use, it suddenly fails to turn on both sides. The overflow valve at the oil inlet of the directional control valve assembly can be disassembled. The reason is that the oil is too dirty, the impurities in the oil wear or strain the surface of the overflow valve core and the inner cavity of the valve body, so that the valve core is stuck in the position where the oil return is turned on,
