Abstract

本项发明涉及一种双端复合齿型迷宫螺旋泵，属通用工程设备技术领域。该泵原理是依靠螺纹齿型工作，目前该泵齿型都是单一齿型。该泵齿型可以设计为矩形、梯形和半圆形等。研究证明，每种齿型都具有独特的性能优势，但每种齿型都具有致命的不足。设计为复合齿型可以发挥每种齿型的性能优势。

Description

双端复合齿型迷宫螺旋泵
技术领域    本项发明涉及一种双端复合齿型迷宫螺旋泵，属通用工程设备技术领域。
背景技术    目前，国内外设计的双端进液式迷宫螺旋泵，理论上可以完全抵消泵的轴向力，提高泵的寿命并增大泵的排量。专利号为ZL97224218.X，其结构如图1所示，被输送介质在电机1转动下，由泵进口法兰2流入安装在泵轴承座3上面的泵转子4和泵体5组成的工作腔体内，通过泵出口法兰6排除。
该泵原理是依靠螺纹齿型工作，目前该泵齿型都是单一齿型。由泵转子4和泵体5组成的工作腔体被称为迷宫螺旋体。在泵转子4外表面和泵体5内表面上分别布满了由单一齿型组成的多头螺纹，根据不同的设计要求，该泵齿型可以分别设计为矩形、三角形、梯形和半圆形等。
研究证明，每种齿型都具有独特的性能优势，但每种齿型都具有致命的不足。迷宫螺旋泵的齿型(泵转子和泵体)设计是关键。
发明内容    本项发明的目的是设计一种双端复合齿型迷宫螺旋泵。是将已具有一种齿型的泵转子的一部分螺纹，改为其它齿型螺纹并均布在泵转子上。此设计可以充分发挥每种齿型的性能优势，并能克服每种齿型特有的不足。
附图说明    图1是已有技术的结构示意图，图2是本项发明的结构示意图。
具体实施方式    下面结合图1和图2附图介绍，1是泵电机、2是泵进口法兰、3是泵轴承座、4是泵转子、5是泵体、6是泵出口法兰。
具体介绍本发明的内容。是将图1已具有一种齿型的泵转子4的一部分螺纹，改为其它齿型螺纹并均布在泵转子4上。图2泵转子4是复合齿型。本项发明的一个实施例齿型为三角形和半圆形螺纹复合组成。

Claims (1)

1、一种双端复合齿型迷宫螺旋泵，包括泵电机、泵轴承座、泵体、泵转子、泵进口法兰和泵出口法兰，其特征在于泵转子的螺纹齿型由两种或两种以上齿型复合组成。
