技術簡介

一種磁浮離心式壓縮機，包括磁浮主軸、止推碟盤、前軸向軸承與後軸向軸承、葉輪及至少一迷宮軸封。止推碟盤連接於磁浮主軸。後軸向軸承與止推碟盤具有第一間隙，前軸向軸承與止推碟盤具有第二間隙。葉輪連接於磁浮主軸。迷宮軸封相對於磁浮主軸之軸向方向傾斜配置，且迷宮軸封係與磁浮主軸及/或葉輪之間具有迷宮軸封間隙，藉由控制止推碟盤於軸向方向上的位置，改變第一間隙與第二間隙的間隙比值，以調整迷宮軸封間隙。此外，一種磁浮離心式壓縮機控制方法亦被提出。

Abstract

A magnetic bearing centrifugal compressor is provided. The magnetic bearing centrifugal compressor includes a spindle with magnetic bearing, a thrust disk, a front axial bearing, a rear axial bearing, an impeller and at least one labyrinth seal. The thrust disk is connected to the spindle with magnetic bearing. The rear axial bearing has a first clearance with the thrust disk. The front axial bearing has a second clearance with the thrust disk. The impeller is connected to the spindle with magnetic bearing. The labyrinth seal is inclined with respect to the axial direction of the spindle with magnetic bearing and the labyrinth seal has a labyrinth seal clearance between the spindle with magnetic bearing and/or the impeller. The clearance ratio between the first clearance and the second clearance is adjusted by controlling the position of the thrust disk in the axial direction to adjust the labyrinth seal clearance. In addition, a magnetic bearing centrifugal compressor controlling method is also provided.

技術規格

葉輪具有一葉輪斜面部，該葉輪斜面部與該迷宮軸封呈同一傾斜角度之傾斜配置，使該葉輪斜面部與該迷宮軸封之間具有該迷宮軸封間隙，且該傾斜角度之範圍為大於0且小於或等於90度。

Technical Specification

The impeller has an oblique surface pairing with the at least one labyrinth seal into a corresponding oblique arrangement, the labyrinth-seal clearance exists between the oblique surface and the at least one labyrinth seal, and an angle between the oblique surface and the axial direction is smaller than or equal to 90 degrees.

技術特色

磁浮壓縮機在葉輪前後設置迷宮軸封，由於無法調整調整迷宮軸封之間隙，來調整氣體洩漏量與控制軸向力的大小。磁浮離心式壓縮機結構配置的改變，來達到調整迷宮軸封間隙之目的，進而能調整氣體洩漏量與控制軸向力的大小，其藉由控制方法，來達到調整迷宮軸封間隙之目的，進而能調整軸向力與控制氣體洩漏量的大小。

應用範圍

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