技術名稱: 離心式壓縮機

技術簡介

一種離心式壓縮機,包括渦殼、渦殼蓋板、葉輪、擴壓器調整組件、徑向組件、軸向組件與驅動組件。渦殼蓋板與渦殼之間形成擴壓器流道與渦道,渦道連通擴壓器流道。擴壓器流道連通葉輪之出口,葉輪可轉動地排出氣體於擴壓器流道,氣體由擴壓器流道通往渦道匯集後排出於離心式壓縮機。擴壓器調整組件包括驅動環、驅動桿、插銷與擴壓器流道寬度調整環。徑向組件設置於驅動環之內圓周面。軸向組件設置於驅動環之外圓周面、頂部與底部之間。驅動組件用以旋轉傳動驅動環轉動。當驅動環被轉動時,藉由插銷移動於驅動環中的插銷軌道,使驅動桿移動,以驅使擴壓器流道寬度調整環移動,來調整擴壓器流道之流道寬度。

Abstract

A centrifugal compressor is provided. The centrifugal compressor includes a volute base plate, a volute cover plate, an impeller, a diffuser adjustment assembly, a radial assembly, an axial assembly, a driving assembly. A diffuser and volute are formed between the volute cover plate and the volute base plate, and the diffuser is connected to the volute. The impeller is rotatably discharged gas through the diffuser and the gas is discharged from the diffuser to the volute and then discharged from the centrifugal compressor. The diffuser adjustment assembly includes a driving ring, a driving rod, a pin and a diffuser ring. The radial assembly is disposed in an inner circumference surface of the driving ring. The axial assembly is disposed between an outer circumference surface, a top surface and a bottom surface of the driving ring. The drive assembly is used to rotatably drive the driving ring to rotate. When the driving ring is rotated, the driving rod is moved by the pin moving to the pin track of the driving ring to drive the diffuser ring to adjust a flow path width of the diffuser.

技術規格

在夏季高壓比工況降載比例為70.6%、在春秋季低壓比工況降載比例為90%。

Technical Specification

The turn down ratio in summer conditions is 70.6%, and the turn down ratio in spring and autumn conditions is 90%.

技術特色

傳統的磁浮離心壓縮機採用轉速搭配進氣導葉機構進行容量調節,受限於組裝與控制技術,無法準確調整氣流與葉片的夾角,容易陷入不穩定運轉區域發生喘震損害壓縮機。可變擴壓器機構機構成功取代傳統之進氣導葉機構,優化磁浮離心壓縮機之降載能力並防止發生喘震;實用性並已完成實際商轉驗證。

應用範圍

應用於流體機械與冷凍空調產業,可應用離心壓縮機產品、鼓風機產品、流體機械等相關應用。
