The Pharma cold chain HS code analysisengine flywheel shell is one of the most important parts in the engine. It can not only protect the flywheel, but also play the role of conducting power to help the whole engine operate normally. This article will introduce in detail the function of the engine flywheel shell, the replacement method and some precautions. I. The function of the engine flywheel shell As a protective device, the main function of the engine flywheel shell is to protect the flywheel in the engine. For those engines that need to start and stop frequently, the importance of the flywheel shell is more obvious.It can avoid damage to the flywheel and prevent other parts from being affected by the rotational force generated by the flywheel. In addition to the above protection functions, the engine flywheel shell also plays an important role, which is to conduct power. The compressed gas inside the engine will generate huge pressure and energy. Without the help of the flywheel shell, these energies cannot be transmitted and utilized, thus affecting the operation of the engine. The design of the flywheel shell gives it a certain gap with the flywheel, which allows the flywheel shell to move with the rotation of the flywheel, thus transferring energy to other parts. II. Replacement method of the flywheel shell When the engine flywheel shell is damaged or malfunctions, we need to replace it. The replacement of the flywheel shell requires not only professional technology, but also some special tools. Before starting the replacement, we need to prepare the following tools: 1.Disassembly tools: including wrenches, screwdrivers, compressors, etc. Two. New engine flywheel shell: Before installation, it needs to check whether its size and shape meet the requirements. 3. Carbon fiber packing: used to fill the gap between the flywheel shell and the flywheel to ensure that they can be tightly combined. The following are the specific steps to replace the engine flywheel shell: 1. The first step is to disassemble the original flywheel shell. You need to use the screwdriver and wrench as a disassembly tool to remove the screw fixing the flywheel shell first. During the disassembly process, you need to pay attention not to scratch the surface of the flywheel. Two. After remoling the old flywheel shell, the surface of the flywheel and the surrounding area need to be cleaned. This can ensure that debris and dirt will not be left when installing the new flywheel shell, which will affect the connection effect. 3. Next, you need to put the new flywheel shell on top of the flywheel and make sure that the gap between them is appropriate.In order to ensure the combination between the flywheel and the flywheel shell, the carbon fiber filler needs to be evenly covered on the surface of the flywheel shell. Four. Screws to fix the flywheel shell are required when installing it. Before fixing, we need to compact the carbon fiber packing. In order to ensure the fixing effect of the screws, we need to apply them with locking agent first and set the correct torque according to the requirements. 5. Finally, we need to check whether the connection between the entire flywheel and the flywheel shell is firm, and whether the operation of the flywheel is normal. III. Precautions When replacing the engine flywheel shell, you need to pay attention to the following issues: 1. Selection of flywheel shell: The flywheel shell needs to match the size and shape of the flywheel. Two. Screw locking: The fixing screw of the flywheel shell needs to use a locking agent and set the correct torque as required. 3. CarbonUse of fiber packing: The packing needs to be evenly covered on the surface of the flywheel shell, and the packing needs to be compacted. Four. Pay attention to safety: When replacing the flywheel shell, you need to turn off the engine and pay attention to relevant safety measures. In a word, as one of the most important parts in the engine, the engine flywheel shell also has the role of conducting power while protecting the flywheel. When replacing the flywheel shell, you need to pay attention to choosing the correct flywheel shell and prepare special tools. When replacing, you need to pay attention to the locking of screws and the use of fillers, and also pay attention to safety measures.
