With the rapid development of social technology and economy, in order to save space, construction units will install some mechanical and electrical equipment on the roofs and floors of the main building or podium,

For example:

1Air cooled heat pump unit

2Outdoor multi split

3Various types of water pumps

4Transformer

5Water chiller unit

6Cooling tower

7Fan

When these devices are in operation, the mechanical vibrations and noise that pervade the living and working environment seriously affect people's normal lives.

1、 Vibration affects engineering quality

1Vibration can directly affect the service life of equipment and even cause damage.

2If the allowable vibration values cannot be met, there may be complaints from the owners

2、 Vibration poses a threat to human health

1Disrupting the normal life of residents and causing functional organ diseases in the human body;

2Long term living in a vibration and noise environment can lead to mental illness due to emotional tension.

3、 Vibration damage to buildings: Prolonged exposure to vibration can cause structural damage to certain buildings. Common damage phenomena include cracking of foundations and walls, peeling of wall skin, sliding of stones, deformation and subsidence of foundations, and in severe cases, the collapse of buildings.

4、 The vibration isolation requirements for vibration equipment are high. Due to design and material reasons, the natural frequency of ordinary rubber and spring dampers is generally high, and spring dampers generally reach7—8HzRubber shock absorbers will arrive12—15HzEven higher. For the low-frequency vibrations generated by the operation of rooftop equipment, especially10HzThe following vibrations have minimal isolation effect. At this point, in addition to durability and appearance, the key to shock absorber products is to require a sufficiently low natural frequency. Jianli Company has developed a new type of low-frequency shock absorber and provided selection and installation methods for it.

Jianli Shock Absorber Manufacturing Co., Ltd. is committed to The research and production of various types of vibration reduction products for electromechanical equipment includes five categories: spring shock absorbers, rubber shock absorbers, thin film air floating shock absorbers, air cushion shock absorbers, steel wire rope shock absorbers, etc., with thousands of specifications, widely covering the field of vibration reduction for electromechanical equipment. At the same time, Jianli Company also provides vibration reduction technology services such as on-site testing, scheme design, and product customization.
