The coil fan shock absorber can significantly improve the noise and vibration problems in residential areas, in addition, it can also improve the management mode of mechanical equipment, improve the expected effect of application and prolong the service life. DH type coil fan bypass valve is designed and manufactured according to the design atlas of China Residential Building Code 0 1(03)K403, which has been widely used in air conditioning engineering. In the air conditioning installation project, the vibration reduction equipment of coil fan can improve the management mode of centrifugal fan, prolong the service life of centrifugal fan and reduce the environmental pollution caused by noise and vibration to the surrounding environment. According to the actual installation requirements of coil fan diesel generator, our company designed and manufactured DH type suspension system spring shock absorber (vibrator). The machine has the characteristics of large shock absorption, low vibration frequency and convenient installation. Especially suitable for living in a geographical environment. Installation and application in places with high requirements.
