Abstract

本发明公开了一种机械密封用泵效环，包括螺旋式泵效，所述螺旋式泵效的一侧连有迷宫式密封。本发明提高了泵效环的泵送能力，加大了密封端面处的流体循环，对密封端面有换热冷却效果，降低了密封端面处流体温度，延长了机械密封的使用寿命。

Description

一种机械密封用泵效环
技术领域
本发明涉及机械密封技术领域，尤其涉及一种机械密封用泵效环。
背景技术
泵效环是指套在密封旋转部件外圆上，依靠其旋转时产生的泵效作用，使密封流体循环流动的器件。
现有技术中，泵效环的泵送能力低，密封端面处的流体循环差，密封端面相互摩擦产生的热量高，密封端面处流体温度高，机械密封使用寿命短。
发明内容
本发明的目的在于克服上述的不足，提供一种机械密封用泵效环。
本发明为实现上述目的所采用的技术方案是：一种机械密封用泵效环，包括螺旋式泵效，所述螺旋式泵效的一侧连有迷宫式密封。
所述的螺旋式泵效与迷宫式密封为一整体结构。
本发明提高了泵效环的泵送能力，加大了密封端面处的流体循环，对密封端面有换热冷却效果，降低了密封端面处流体温度，延长了机械密封的使用寿命。
附图说明
图1是现有技术示意图；
图2是本发明示意图。
其中：1、螺旋式泵效  2、顶丝  3、传动套  4、迷宫式密封  。 
具体实施方式
如图2所示，一种机械密封用泵效环，包括螺旋式泵效1，所述螺旋式泵效1的一侧连有迷宫式密封4；所述的螺旋式泵效1与迷宫式密封4为一整体结构；迷宫式密封4的齿宽、齿高及与泵盖的间隙依据工况参数不同有不同的设计尺寸。
本发明通过顶丝2安装在传动套3上。

Claims (2)

1.一种机械密封用泵效环，包括螺旋式泵效（1），其特征在于：所述螺旋式泵效（1）的一侧连有迷宫式密封（4）。
2.如权利要求1所述的机械密封用泵效环，其特征在于：所述的螺旋式泵效（1）与迷宫式密封（4）为一整体结构。
