AI Technical Summary

Technical Problem

The introduction of heat insulation plates into existing centrifugal pumps under high-temperature conditions has led to significant vibration and noise problems, with noise levels exceeding standards, thus affecting equipment reliability.

Method used

A hollow cavity running through the thickness of the insulation board is made, and a vibration damping coating is applied to the surface of the insulation board. Combined with vibration damping springs, a suspended channel is formed to break the vibration transmission path. At the same time, the spatial layout is optimized to increase the gap of the ventilation channel.

Benefits of technology

It effectively reduces vibration and noise, improves thermal insulation performance, and lowers noise levels by 8-10dB, achieving both thermal insulation and noise reduction effects.

Abstract

The utility model discloses a centrifugal pump and heat insulation board thereof belongs to centrifugal pump noise reduction field. The utility model's centrifugal pump, including base and box seat, install control panel in box seat, and the heat insulation board is connected between base and box seat, and the heat insulation board is used for the heat transfer between base and box seat, the heat insulation board is opened and has the openwork cavity that penetrates its thickness direction, and the openwork cavity both ends respectively face the top surface of base and the bottom surface of box seat, and the top surface of base does not extend to openwork cavity, and the bottom surface of box seat also does not extend to openwork cavity, make the openwork cavity bottom end and the top surface of base between, and openwork cavity top end and the bottom surface of box seat between all have a certain height's axial gap. The utility model can effectively alleviate the noise problem on the basis of guaranteeing its heat blocking effect through the optimization design to the heat insulation board.
