Description

立式自吸泵密封体
技术领域
本实用新型涉及立式自吸泵上的密封体。
背景技术
立式自吸泵的密封体有兼作密封与支承轴承体作用,但有现有密封体的长度尺寸长,径向尺寸变化大,给加大带来很大的困难,且密封体下部分起密封作用与介质接触,必须进行压力试验,所以给试压也带来不便,另由于上部分未与介质接触,不需耐腐蚀材质,现有的浪费材料。
发明内容
本实用新型的目的就是提供一种加工方便、试压简便、节约原材料的立式自吸泵密封体。
本实用新型的主要技术方案如下:
立式自吸泵密封体分为密封座和轴承体两部分,密封座上端面设有螺孔,轴承体下端面设有光孔,通过螺钉将密封座与轴承体连为一体。
密封座与泵体外径连接,端面用聚四氟乙烯垫密封;轴承体下装有法兰,用螺栓与泵体联接。
本实用新型具有加工方便、试压简便、节约原材料的优点。
附图说明
图1是本实用新型立式自吸泵结构示意图;
图2是本实用新型的密封座结构示意图;
图3是本实用新型的轴承体结构示意图。
具体实施方式
如图所示,立式自吸泵密封体分为密封座5和轴承体6两部分,密封座5与泵体1外径采用H7/H6连接,端面用聚四氟乙烯垫密封;轴承体6内止口与密封座5外圆用采用H7/H6配合,轴承体下装有法兰,用螺栓与泵体联接。密封座5上端面设有螺孔3,轴承体下端面设有光孔4,通过螺钉2将密封座与轴承体连为一体。这样,密封体长度尺寸大小加式方便,试压方便,轴承体不与介质接触,材料采用HT250灰铸铁,不需试压。大大地节省了贵重材料,保证了加工精度。
