Main uses and characteristics of damping spring shock absorber
Damping spring shock absorber is a kind of spring shock absorber that we are familiar with. It is also called prestressed spring shock absorber. The so-called prestress is actually the compressive stress applied to the structure in advance to offset or reduce the tensile stress generated by external loads and maintain the structure from being damaged. This method is the most commonly used method in concrete construction, and is usually used in shock absorbers, which increases the acceptance ability of spring shock absorbers.
Then the main purpose of the damping spring damper is to isolate the vibration of large mechanical equipment such as water chillers, cooling towers, heat pump units and generator sets.
Characteristics of damping spring damper:
1. The main characteristic is that it has two kinds of shock absorber characteristics, namely, the low frequency of spring shock absorber and the large damping of rubber shock absorber, which eliminates the low amplitude of rubber shock absorber and the resonance amplitude of spring shock absorber; 2. Wide load range, users do not need to worry about the trouble of selection;
3. Low natural frequency, good vibration reduction and isolation effect;
4. Compact structure, small size, no need for professionals to install;
5. When used, it is not only safe and reliable, but also has a long working life compared with other types of shock absorbers;
6. There is not much demand for the workplace. The most bearable thing for users is that its applicable temperature range is - 40 ℃ to 110 ℃, which is incomparable for many shock absorbers.
From the above characteristics, we can see the strength of the damping spring shock absorber. It not only stops the vibration reduction, isolation and silencing of the vibrating equipment, but also plays a maintenance role, greatly extending the service life of the equipment. To quote a phrase: this is a necessary shock absorber to manage vibration, isolate vibration and reduce noise.

Five Tips for Leakage Treatment of Pneumatic Control Valve
Method 1: add sealing grease method; This method is aimed at the valve body that has not used the sealing grease, and it can be considered to increase the sealing grease to improve the sealing performance of the valve stem. It is also one of the necessary maintenance procedures to add sealing grease during routine maintenance of pneumatic control valve.
