What harm will the aging of rubber shock absorber bring
No matter rubber shock absorber, spring shock absorber or other shock absorbers in the car are aging, they will bring incalculable hazards, and these hazards may cause traffic accidents, even endanger the safety of drivers, passengers, other vehicles and pedestrians around! So just replace the shock absorber with any aging phenomenon in time!
It is quite clear that not only the professional auto repair masters but also some drivers who have the ability to repair cars themselves. The shock absorber is usually installed in the suspension system beside the car tire. It is usually used to reduce the vibration of the car through the cooperation with the spring, so that the car can run smoothly. After the car has been used for a long time, if drivers do not regularly check the habits of the shock absorber, they will not know its condition. That will always present the traffic accidents I mentioned above. What harm will the aging of shock absorber bring?
1. When the shock absorber is aged, the steering wheel tends to malfunction when the user stops a sharp turn. If there are no obstacles and the road is relatively smooth when making a sharp turn, will it have any impact? Just let the driver know how to jump faster. However, if the sharp turn is to avoid vehicles, or the road has a great inclination and the terrain is very bad, it is likely to have a traffic accident;
2. When the shock absorber is aged, the starting and braking of the car will have a strong sense of stability, giving passengers considerable discomfort. For this reason, whether from the perspective of safety or warmth, drivers should regularly check the aging condition of the shock absorber. If the aging condition of the shock absorber is found, it needs to be replaced in a timely manner.
Car safety is not only about standard operation and driving according to traffic rules, but also about checking car parts and taking care of them regularly!

How to do flexible waterproof casing will increase cost
The embedded rigid waterproof bushing also has a defect, that is, it is not allowed to be installed. During the construction phase of flexible waterproof housing, the reference object of the embedded size of the toilet waterproof housing atlas is only the location and size of the beam and pole structure, and the latter often has a tendency. This will lead to the location and size of the embedded casing will also have a tendency, which will bring inconvenience to future construction, Especially for houses with exquisite decoration, because of the large location of drainage pipes, it will often constitute rework and increase costs
For example, the outer diameter of the flexible waterproof shell is 426, the inner diameter of the pipe is 426, and the inner diameter of the pipe is 406. The design drainage pipe has a good size, and the outer diameter of the flexible waterproof shell is 480. There is a gap between the installation and the drainage pipe. The filling materials are usually asphalt, asbestos cement, oil tank and other materials, and the general suitable temperature is - 20c - 250c
In addition to the tendency of standard understanding, the construction unit often considers that the rigid waterproof casing has higher costs and higher profits. Taking DN100 rigid waterproof casing as an example, the construction of embedded casing is relatively simple, so the construction unit is urged to use rigid waterproof casing
There is no casing set, and a method of sticking to the hole is adopted. This method is relatively conventional. During the construction phase, holes are reserved in the form of wooden shells. The pipeline is blocked before installation, and the pipeline itself is properly disposed before blocking. The disposal method is to dispose of the outer wall of the pipeline or apply glue and sand; Waste plastic sealing ring is directly used for the outer wall of the pipe
