Abstract

本发明耐腐蚀泵静环座装置由钢壳1、耐蚀块2和静环座3组成。耐蚀块2和静环座3被加设在钢壳1的凸出面4分隔于两侧,二者间的结合面5密封固定连接。这种结构使耐蚀块2只受到来自泵壳的压力,不存在剪应力作用于耐蚀块2上。解决了耐蚀块2破碎或变形的问题。

Description

耐腐蚀泵静环座装置
所属技术领域:
本发明耐腐蚀泵静环座装置用于采用机械密封式轴封装置的耐腐蚀泵。
背景技术:
原耐腐蚀泵静环座与泵盖的耐腐蚀块为整体结构,安装时由一侧装入钢壳内。当安装泵时,由于来自泵盖前后的外部作用力相反。在耐蚀块上产生了剪应力。由于耐蚀块为非金属材料,性脆或强度低。因此常发生耐蚀块破碎或变形的现象。使泵盖报废。
发明内容:
本发明耐腐蚀泵静环座装置的目的是提供一种新结构的耐腐蚀泵盖,解决泵后盖耐蚀块被压碎或变形的问题。本实用新型是这样实现的:将耐蚀块由原来的整体结构改为由耐蚀块2和静环座3两部分组成,钢壳在耐蚀块2与静环座3间设有一凸面4。静环座3设有的台肩与钢壳1的凸出面4底部相接触,耐蚀块2设有台肩与钢壳1的凸出面4上部相接触。安装时耐腐蚀块2和静环座3分别从两侧装入,二者结合面5密封固定连接。本发明的优点是:外部通过静环座3作用于设有凸出面4的钢壳1上,耐蚀块2不在受来自外部前后两个方向的压力,只是受泵壳的压力。这样耐蚀块2上无剪应力形成,也就不会使耐蚀块2破碎或开裂。
附图说明:
图1为本发明耐腐蚀泵静环座装置主视图
最佳实施例:
如图所示,本发明耐腐蚀泵静环座装置由钢壳1、耐蚀块2和静环座3组成。耐蚀块2和静环座3间被加设在钢壳1的凸出面4分隔于两侧,二者的结合面5密封固定连接。这种结构使耐蚀块2只受来自泵壳的压力,无剪应力作用于耐蚀块2上。这样就不会使耐蚀块2破碎或变形。
