Abstract

本实用新型公开了一种机械密封用泵效环,包括螺旋式泵效环,所述螺旋式泵效环的一侧连有迷宫式密封结构。本实用新型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
本实用新型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。 
实用新型内容
本实用新型的目的在于克服上述的不足,提供一种机械密封用泵效环。 
本实用新型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,包括螺旋式泵效环,所述螺旋式泵效环的一侧连有迷宫式密封结构。 
所述的螺旋式泵效环与迷宫式密封结构为一整体结构。 
本实用新型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是本实用新型示意图。
其中:1、螺旋式泵效环  2、顶丝  3、传动套  4、迷宫式密封结构。 
具体实施方式
如图2所示,一种机械密封用泵效环,包括螺旋式泵效环1,所述螺旋式泵效环1的一侧连有迷宫式密封结构4;所述的螺旋式泵效环1与迷宫式密封结构4为一整体结构;迷宫式密封结构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。 
本实用新型通过顶丝2安装在传动套3上。 

Claims (2)
