压力匹配器隔音罩设计

Enclosure Design for Pressure Matcher

文章通过对压力匹配器隔音罩的设计与制作,以及后期模块受力测试、隔音测试,得到一种生产便捷且成本低的隔音罩,隔音罩模块间采用弹性拉动式锁扣连接,便于快速拆卸安装。通过进气、排气消音模块的设计,以及进风口、排风口面积计算解决了设备散热问题,并达到了隔音效果。某电厂压力匹配器安装后实测隔音量达到19.55 dB(A)。此隔音罩设计完全适用于电厂辅机设备中压力匹配器、给水泵、减温减压器、罗茨风机、引风机等各种风机、泵设备,也适用于球磨机等工业设备。

Based on design and manufacture of pressure matcher and following stress test,sound insulation test of module,the paper get a kind of enclosure which is easy to manufacture and low in cost.The enclosure modules are connected by elastic pullbased lock to facilitate quick disassembly and installation.Through the design of air intake and exhaust noise reduction module,as well as the calculation of air intake and exhaust area,the heat dissipation problem of the equipment is solved and a good noise reduction is obtained.The measured noise reduction is up to 19.55 dB(A)after pressure matcher of a power plant installed.This enclosure is completely applicable to all kinds of fans and pump equipments in power plant auxiliary equipments,such as pressure matcher,feed water pump,temperature and pressure reducer,Roots fan,draft fan,etc.,as well as industrial equipments such as ball mill.
