A pipeline vibration isolation device that can display the vibration isolation frequency and adjust the balance position

Abstract

The invention provides a pipeline vibration isolation device capable of displaying a vibration isolation frequency and adjusting a balance position. The device comprises a split metal snap ring, bearing elastic elements, a load balance position displaying and marking assembly and an elastic element position adjusting device, wherein the split metal snap ring is connected with and fixed to a vibration isolation object through a bolt or a bayonet; the bearing elastic elements are connected in series and / or in parallel according to a preset angle, and bearing and transferring the load of the polarized object; the load balance position displaying and marking assembly is used for acquiring and displaying the vibration isolation frequency when a vibration isolator is subjected to load; and theelastic element position adjusting device is connected with the load balance position displaying and marking assembly so as to adjust a relative position between the bearing elastic elements and the vibration isolation object according to the frequency, so that the load borne by the vibration isolator meets a preset frequency requirement. According to the pipeline vibration isolation device, on the basis of meeting the rigidity and damping requirements of vibration isolation, an actual load static balance position mark display function and a static balance height position adjusting function are introduced, and the device has the characteristics of capable of detecting the vibration isolation frequency and adjustable the static balance position, and solves the problem that the frequency andthe balance position cannot be determined.

Description

technical field [0001] The invention relates to the technical field of structure and device vibration isolation, in particular to a pipeline vibration isolation device capable of displaying the vibration isolation frequency and adjusting the balance position. Background technique [0002] As we all know, many power systems have huge pipeline systems. The pipeline system not only transmits liquid, but also affects the quality characteristics of power machinery. In addition, fluid movements such as liquid pressure pulsation and turbulence generate vibration at the same time. In order to reduce the transmission of pipeline vibration to the structure, vibration isolation of the pipeline is required. However, the difficulty of pipeline vibration isolation lies in the flexibility of the pipeline. Due to the existence of flexibility, the load of each support or suspension point is affected by other points. The operating frequency of the vibration isolation device may not be within...

AI Technical Summary

Problems solved by technology

[0003] The design of traditional vibration isolation devices assumes that the load of the object to be isolated is known, therefore, it does not have the ability to deal with the above problems

In addition, in order to reduce costs, many vibration isolation devices use rubber materials as elastic elements, but rubber elastic elements have strong nonlinear characteristics, which also affects the vibration isolation effect
