Embodiment Construction

[0027] As mentioned in the background section, current liquid dampers have low flexural strength.

[0028] Based on the above research, the embodiment of the present invention provides a liquid damper, which is connected to the equipment that needs vibration isolation. When the equipment vibrates, it will drive the connection cavity to vibrate up and down. The long cylinder shaft pushes the lower shaft end cover to move downward, so that the lower bellows is compressed, and at the same time, the long cylinder shaft pulls the upper shaft end cover to move downward, so that the upper bellows is stretched, so that the damping fluid in the lower bellows passes through the guide rod The gap between the shaft and the long tube shaft enters the upper bellows, and the vibration energy is dissipated under the action of the deformation of the bellows and the damping channel formed by the gap between the long tube shaft and the guide rod. In addition, the principle of the upward movement...

Abstract

The invention discloses a liquid damper. The liquid damper comprises an upper outer cylinder, an upper inner cylinder, an upper corrugated pipe, an upper shaft end cover, a middle cylinder, a connecting cavity, a lower shaft end cover, a lower cylinder and a guide rod; the connecting cavity comprises a long cylinder shaft and multiple support arms; the guide rod vertically penetrates through the long cylinder shaft; the upper end of the guide rod is fixedly connected to the inner top of the upper inner cylinder, and the lower end of the guide rod is fixedly connected to the inner bottom of the lower cylinder; two ends of the middle cylinder are fixedly connected with the bottom of the upper inner cylinder and the upper part of the lower cylinder; guide grooves corresponding to the support arms one to one are vertically formed in the side wall of the middle cylinder; the upper shaft end cover is tightly connected with the long cylinder shaft; the lower shaft end cover is tightly connected with the long cylinder shaft; two ends of the upper corrugated pipe are tightly connected with the upper inner cylinder and the upper shaft end cover; and two ends of the lower corrugated pipe are tightly connected with the lower cylinder and the lower shaft end cover. As the upper end of the guide rod is fixedly connected with the upper inner cylinder, and the lower end is fixedly connected with the lower cylinder, the consumption of vibration energy by the deformation of the upper and lower corrugated pipes is guaranteed, and the bending strength and the service life of the liquid damper are improved.

Description

technical field [0001] The invention relates to the field of dampers, in particular to a liquid damper. Background technique [0002] In aviation, aerospace and machinery industries, dampers have been widely used for energy dissipation and shock absorption to ensure normal and effective operation of equipment. [0003] However, it is difficult to ensure the bending strength of the damper while ensuring the sensitivity of the existing damper. Therefore, after a long period of frequent use, problems such as damage or worsening damping effect will occur. [0004] Therefore, how to provide a liquid damper with high bending strength while ensuring sensitivity is an urgent technical problem to be solved by those skilled in the art. Contents of the invention [0005] The purpose of the present invention is to provide a liquid damper, which can effectively solve the problems of difficulty in balancing sensitivity and bending strength. [0006] In order to solve the problems of t...
