Abstract

The invention discloses a vibration damping device, a compressor and a water chilling unit. The vibration damping device comprises a shell, a connecting piece, a damper spring and damping particles. The shell is provided with a vibration damping cavity. The connecting piece is arranged on the shell in a penetrating mode, and the connecting piece is provided with a connecting end and a vibration damping end. The connecting end of the connecting piece is located outside the vibration damping cavity and used for being connected with a vibration source, and the vibration damping end of the connecting piece is located in the vibration damping cavity. The damper spring is installed in the vibration damping cavity. The first end of the damper spring is connected with the connecting end of the connecting piece, and the second end of the damper spring is connected with the inner wall of the shell. And the damping particles are filled in the vibration damping cavity. According to the vibration damping device disclosed in the invention, vibration energy of the vibration source can be fully dissipated and absorbed through the mutual cooperation of the damper spring and the damping particles, and therefore the vibration damping effect is improved.

Description

technical field [0001] The invention relates to the technical field of water chillers, in particular to a vibration damping device, a compressor and a water chiller. Background technique [0002] At present, the vibration performance requirements of chillers are still getting higher and higher. As the vibration excitation source in the whole machine, the compressor's vibration reduction and vibration absorption measures have always played a decisive role in the vibration effect of the whole machine. Therefore, in order to improve the overall vibration effect of the whole machine, economy and realizability are considered at the same time. [0003] The existing dynamic vibration absorbers are divided into active type and passive type. Active dynamic vibration absorbers need to integrate signal acquisition and feedback in the control system of the whole machine, analyze the vibration frequency collected by the vibration, and control the vibration absorber to generate anti-phase...
