How to improve the sound insulation effect

In the "rubber parts" of automobiles, the function of the sealing strip is first to "stop shock". Reducing vibration reduces the air vibration caused by the resonance of the body parts, and the air vibration will cause sound waves (noise). But the sealing strip of the original car is sufficient to control vibration, no matter whether the door and the body or the hood and the engine compartment are in direct contact, the lock and the sealing strip will ensure the rationality of the gap.

If the hydraulic hose has quality assurance, if it is damaged, it should not be used normally. The first is the installation process. At the same time, always check the hydraulic hose during normal use. Here, below I have recorded the points that need to be paid attention to during ordinary homework:

1. Do not twist the high-pressure hose when installing it for the first time, otherwise the hydraulic hose will be damaged or the joint will be loose.

2. Install high-pressure rubber hoses between the objects, leaving a certain space to avoid friction between the high-pressure rubber hoses and the objects during operation. If not, try to get some protection. For example, use a high-pressure hose sheath.

3. During normal operation, the valve stem should not be pulled too strongly, but it needs to be gentle, otherwise the high-pressure hose will burst.

4. In order to avoid damage to the high-pressure hose and limited flow rate, the bending radius should be increased as much as possible.

5. When the temperature rise of the hydraulic system is too high during operation, the high-pressure oil pipe should be checked in time, and necessary cooling measures should be taken during continuous operation.

6. When the bending radius of the hydraulic hose is too small, a right-angle joint is usually used to avoid sharp bending and twisting of the hose.
