Description

一种无泄漏离心泵
技术领域
本实用新型涉及一种离心泵，具体涉及一种无泄漏离心泵。
背景技术
传统的离心泵只包含了工作叶轮及机械密封或填料密封，填料密封在运行一段时间或过了磨合期就会造成泄漏，机械密封使用一段时间也会造成泄漏。提高了泵的维修频率和维修成本。
发明内容
本实用新型的目的在于提供一种密封性能好的无泄漏离心泵。
本实用新型采取的技术方案为:
一种无泄漏离心泵，包括泵壳，泵壳上设有出水口和进水口，泵壳内安装有转轴，转轴的伸入端端部安装有工作叶轮，泵壳一侧的端面上安装有泵盖，转轴穿接泵盖，转轴上套有轴套，轴套与泵盖内孔壁间由内而外依次安装有迷宫密封和油封，端盖的外端面上安装有油封压盖，油封压盖挤压油封，所述工作叶轮与泵盖间设置有密封叶轮，密封叶轮固定安装于转轴。
采取以上技术方案后，本实用新型的有益效果为：泵在运行时，由于密封叶轮的同步旋转，产生和工作叶轮同样的压力后，就平衡了泵产生的压力，同时由于迷宫密封的作用避免了输送介质向密封腔流动的可能，泵在停止运行时，此时泵处于需静密封状态，再加装了油封后，确保了液体无泄漏的可能，从而保证了设备的稳定运行。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
以下结合附图对本实用新型的具体实施方式做进一步详述
如图所示，一种无泄漏离心泵，包括泵壳1，泵壳1上设有出水口2和进水口3，泵壳1内安装有转轴4，转轴4的伸入端端部安装有工作叶轮5，泵壳1一侧的端面上安装有泵盖6，转轴4穿接泵盖6，转轴4上套有轴套7，轴套7与端盖1内孔壁间由内而外依次安装有迷宫密封8和油封9，泵盖6的外端面上安装有油封压盖10，油封压盖10挤压油封9，所述工作叶轮5与泵盖6间设置有密封叶轮11，密封叶轮11固定安装于转轴4。
