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.

Several key points of stainless steel pneumatic butterfly valve selection
The size is the nominal diameter of the hose, the type of connector (mainly flange connection, thread connection, quick connection), the length of the pneumatic butterfly valve, and the length of the hose.
Stop the pressure according to the practical working pressure of the hose, and then check the nominal diameter and pressure gauge of the corrugated pneumatic butterfly valve to determine whether the stainless steel mesh sleeve pneumatic butterfly valve can be used.
According to the chemical properties of the medium in the medium hose and the corrosion resistance of the hose, confirm the information of each part of the hose.
Operating temperature and range of medium in temperature hose; Hose operating ambient temperature. At high temperature, it is necessary to stop correcting the correction coefficient of working pressure and temperature at high temperature of pneumatic butterfly valve to confirm the corrected pressure and correct selection of pressure level.
When using the hose, refer to the correct use of pneumatic butterfly valve and hose, and the device method of length compensation in settlement The number and length of small bends, the movement state of the hose and the small bending radius and other parameters, correctly select the hose length and the correct device.
