Abstract

The invention discloses a self-adjusting hydraulic vibration isolation system for HVAC machinery, which includes a hydraulic cylinder, a hydraulic system and a control system. The first pipeline of the hydraulic system is sequentially connected with a hydraulic oil tank, an oil filter, a hydraulic pump, and a hydraulic control unit A directional valve and an accumulator, and at least four hydraulic cylinders communicate with the first pipeline between the hydraulic control check valve and the accumulator. One end of the second pipeline communicates with the overflow valve and the other end communicates with the first pipeline between the hydraulic pump and the hydraulic control check valve. The first two-position two-way valve communicates with the overflow valve through the third pipeline. Multiple sets The parallel valve group including the overflow valve and the second two-position two-way valve communicates with the remote control port of the overflow valve through the fourth pipeline. The sensor installed on the hydraulic cylinder transmits the vibration frequency and displacement data of the HVAC machinery to the PLC, and the PLC controls the two-position two-way valve to adjust the pressure of the hydraulic system according to the transmitted data. The system of the present invention does not need manual timing adjustment.

Description

technical field [0001] The invention relates to an HVAC machine room vibration damping system, in particular to an automatically adjustable hydraulic vibration isolation system. Background technique [0002] When the HVAC mechanical parts work, they will generate vibration and affect the operation of the instrument. They need to be placed on the vibration isolator to reduce the vibration. As an important equipment for vibration reduction in HVAC machinery, vibration isolators can effectively reduce the transmission of vibration between HVAC machinery to the base and other equipment, thereby reducing the harmful effects of vibration on instruments and operators. At present, there are several types of large-load vibration isolators widely used, such as metal rubber vibration isolators, steel spring vibration isolators, and rubber vibration isolators. Plastic deformation, the thickness of the elastic element decreases, and the performance changes, which seriously affects the v...
