Abstract

湿杯喉部密封(3)和轴承(2)结合设计成用于往复式活塞泵，其中湿杯(1)设计成用于保持密封装置，以便确保移动杆(5)的正确对正和最大密封寿命。此装置还允许容易和便宜地更换活塞密封(6)和喉部密封(3)，且允许它们的互换。

Description

湿杯喉部密封和轴承装置
技术领域
设计一种用于往复式活塞泵的湿杯喉部密封和轴承组合结构，其中湿杯用于保持密封装置。
背景技术
湿杯和喉部密封用于往复式活塞泵是公知的。虽然已有技术的装置通常是令人满意的，还是希望在降低成本的情况下提高制造的容易性，密封寿命和使用的容易性。
发明概述
湿杯由六角不锈钢杆坯加工而成。轴承是用缩醛杆加工的切口轴肩轴承。喉部密封是标准的U形杯密封。湿杯和轴承装配到一个开口套中。轴承给往复杆导向，当往复杆往复运动时密封防止泄漏。
湿杯和缸体尺寸设计成活塞密封和喉部密封可互换。轴承上的台阶确保轴承与湿杯和泵共线。通过从开口套上拧下湿杯，以及不用工具地从湿杯上拆下轴承和喉部密封，能够操作此结构。
通过下面的说明书连同附图，本发明的这些和其它目的和优点将进一步更加完全显露，其中在几幅视图中类似的标号表示相同或类似的部件。
附图说明
图1是利用本发明湿杯轴承和密封装置的泵的分解图。
图2是本发明湿杯轴承和密封装置的分解图。
图3是本发明湿杯轴承和密封装置的横截面图。
本发明的最佳实施方式
湿杯1由六角不锈钢杆加工而成。轴承2是用缩醛杆加工的切口轴肩轴承。喉部密封3是标准的U形杯密封。由图1，2和3所示装配此组合。湿杯1装配到开口套4内且轴承2装配到开口套4上。轴承2引导往复杆且当往复杆运动时密封3防止泄漏。
湿杯1和缸体7按尺寸设计成活塞密封6和喉部密封3是可互换的。这样的组合结构确保在酸催化漆中长的密封寿命而不需要调整密封。轴承的轴肩确保轴承与湿杯和泵共线。通过从开口套4上拧下湿杯1，以及不用工具地从湿杯上拆下轴承2和喉部密封3，能够操作此结构。不要求拆下往复泵的剩余部分。
在喉部密封失效而没有备件在手的情况下，可以转换向下朝向的活塞密封和喉部密封来继续运转此泵。
在不偏离由下面的权利要求限定的本发明的精神和范围的情况下，可以设想此装置的各种变化和改进。
