Vibration damping device and water chilling unit

Abstract

The invention discloses a vibration damping device and a water chilling unit. The vibration damping device comprises a vibration damping assembly, a first bracket and a second bracket; the vibration damping assembly comprises a first vibration damper and a second vibration damper, the first vibration damper is arranged on the second vibration damper, and a deformation space for absorbing vibrationis formed between the first vibration damper and the second vibration damper; the first bracket is fixedly arranged on the first vibration damper, and the first bracket is connected to a vibrating object; the second bracket is fixedly arranged on the second vibration damper, and the second bracket is connected to a supporting object. According to the vibration damping device and the water chilling unit, the first vibration damper is arranged on the second vibration damper, the deformation space for absorbing vibration is formed, and therefore the vibration attenuation and vibration isolationeffects are achieved; the first bracket connected with the vibrating object and the second bracket connected with the supporting object are arranged, rigid supporting is achieved, the vibration damping device can still achieve effective vibration isolation under the condition that rigid installation is satisfied.

Description

technical field [0001] The invention relates to the technical field of water chillers, in particular to a vibration damping device and a water chiller. Background technique [0002] The vibration value of the installation feet of ship chillers is an important assessment index for military equipment. The unit is usually assembled from bottom to top by the base, shell and tube heat exchanger, compressor and other structures, and the installation feet are distributed on the base. This structural feature determines that the shell-and-tube heat exchanger structure is the most important vibration transmission path between the compressor (vibration source) and the installation point (vibration assessment point). Therefore, in order to reduce the vibration at the position of the machine foot, the optimal vibration isolation scheme is to carry out vibration isolation design between the compressor and the shell-and-tube heat exchanger, and between the shell-and-tube heat exchanger an...

Therefore, in order to reduce the vibration at the position of the machine foot, the optimal vibration isolation scheme is to carry out vibration isolation design between the compressor and the shell-and-tube heat exchanger, and between the shell-and-tube heat exchanger and the base structure. Installing a shock absorber between the shock absorber and the base will cause stability problems for the entire unit
