How to take care of spring shock absorber is correct
The spring shock absorber is very popular with many customers because of its obvious damping effect. In fact, it is also endurable because it is made of metal, so its service life is longer than other types of shock absorbers. But it is not to say that metal is durable and will not be taken care of at home. In fact, spring shock absorbers also need to be taken care of at home, but the period of taking care of them is longer.
The spring shock absorber is made of special metal materials, and its body is hot-dip galvanized, so its appearance is light and consolidated, and it has a long service life. However, users should not ignore their daily care work. As long as the spring shock absorber is well maintained, it can extend its service life and bring its application effect into the best working condition.
First, generally speaking, since the spring shock absorber has excellent anti-corrosion and antirust functions, it does not need to work too hard for it to take care of itself. The best period for taking care of itself is once a year. For the smooth oil used in home care, it is better to use the oil that can accept heavy load, and it is suitable to use the smooth oil containing molybdenum disulfide.
Second, to maintain the normal working state of the spring damper, it is necessary to stop regular inspection and management.
The spring shock absorber plays an important role in the automobile industry, and its damage will bring great security risks. Therefore, it is necessary to regularly check the parts to see if they are damaged. If they are damaged, they should stop changing and repairing immediately. Generally speaking, it mainly checks whether the piston, piston rod, oil storage cylinder, working cylinder, tightening valve, flow valve, recovery valve, compensation valve, guide component, sealing component and other parts are damaged. Regular inspection is beneficial to better use of spring damper.
It can be said that the quality of the spring shock absorber in the car directly affects the car performance and traffic safety hazards. Therefore, we should carefully check every detail during the period of recuperation.

Analysis of the bending capacity and design requirements of the compensator
The direct buried corrugated compensator is mainly applicable to axial compensation, and has super bending resistance, so it does not consider the impact of pipe sinking. The direct buried corrugated compensation shell and guide sleeve can complete the self expansion compensation under the maintenance of the guide sleeve. Other performances are the same as those of ordinary corrugated compensator.
Precautions for device:
1. In order to make the direct buried corrugated compensator play a compensation role, fixed supports must be set at both ends of the compensator to avoid the pipeline from being affected by internal pressure and thrust.
2. One end of the directly buried corrugated compensator (refers to the dead end of the directly buried compensator with one-way compensation) shall be close to the fixed support at one end, and the flexible head of the compensator shall be used to compensate the pipeline.
3. The interval between the two fixed supports is set according to the compensation amount of the direct buried corrugated compensator, and the compensation amount is generally not greater than the pipe diameter.
4. During the pressure test, the directly buried corrugated compensator shall not show tensile phenomenon.
The angular compensator is composed of a compensator receiver, a bellows and a pair of hinges connected with the receiver. It can only absorb the angular displacement of a single plane. When absorbing displacement, two or three angular compensators shall be used in combination, and the hinge can accept internal pressure thrust. Working temperature ≤ 420 ℃, fatigue life 1000 times.
Requirements for pipe support design:
Two or three angular type compensators should be used as a group to absorb the lateral displacement of the pipeline. Only one transverse type compensator or a group of angular type compensators can be installed between two fixed pipe supports of Z-shaped and L-shaped pipe sections. At this time, the axis of the plane hinge pin must be perpendicular to the plane formed by the bent pipe section (universal hinge compensator is not subject to this restriction). Clearance of plane guide frame of pipe section with a group of hinge compensators ε It can also be calculated according to the above formula. However, L length shall be the interval between hinge axes of two compensators, and △ X is the thermal shrinkage of the whole vertical pipe section.
