Abstract

一种用于往复式活塞泵的密封组件,其具有较紧密的公差和增加的密封期限。

Description

泵杆上的密封件
用于涂料和其它粘性材料的往复式柱塞泵已经为人们所熟知。虽然已有的设计大致可以满足其预定的用途，使用者经常想增加其密封期限，以防止工作和生产的中断。
因此本发明的目的是提供一种泵，其能很容易地制造并低成本地制造。
本发明用于减少部件和组装时间，提供一种非调节式密封组件，并且有增加的组件高度，这可以提高承载能力，并且运转与圆筒类似，这可以在标准的密封期限上增加50％并且消除了对力矩敏感的密封调整。
泵杆机械加工成带有一个台肩，提供一个区域使得密封件和密封套可以滑到杆上。这可以提供准确的对准并且离杆的上部有一定的距离，并且喉部密封件和密封套也可以和其对准。这可以减小侧向负载和在两套密封件和密封套之间的扭曲。还提供了一个整体的活塞，其能旋进活塞杆的端部并挤压密封组件至预定的挤压公差，并消除多个组装件和用于密封件的力矩设置。
一个额外的革制品和UHMWPE密封加到活塞上以消除任何活塞的摇动，这会引起密封套相对圆筒的磨损，从而会导致寿命减短。利用本发明的各种特征，密封期限相对与现有设计的密封期限增加了50％。
活塞寿命增加超过50％，活塞杆和上喉部密封件和密封套之间的精确对准以及精确的公差。密封件预加载至预定的压缩公差，以便容易地安装和维修。本发明的组件包括一个活塞带有一个转矩螺母用于组装活塞头和活塞杆。这使得距离间隙由活塞和活塞头以及转矩螺母和LOCTITE的螺纹来限定。这种设计会导致过早的活塞失效。
本发明的这些和其它目的和优点将结合附图进行更详细的描述。其中各附图中同样的附图标记表示同样或类似的部件。
图1是详细示出本发明的剖视图；
图2是包含本发明的泵的剖视图；
图3是包含本发明的泵的分解图。
本发明总的标为10，其包括一个圆筒12，其上有一个套14，具有台肩16a的活塞杆16，和密封套20，以及一个喉部密封套22。
可以理解在不脱离权利要求中所限定的本发明的精神和范围的前提下，对泵的设计可以进行各种变化和修改。

Claims (3)

1．一种往复式活塞泵，其包括一个有上端和下端、并在圆筒内往复运动的活塞杆，在上端和下端之间有密封件，其特征在于，所述活塞杆沿其圆周有一凸出部分，所述密封件能被握持，并且位于所述活塞杆上，以在往复运动时随活塞杆运动。
2．如权利要求1所述的往复式活塞泵，其中所述密封件相邻于所述活塞杆的下端。
3．如权利要求1所述的往复式活塞泵，其还包括一套在所述圆筒和所述活塞杆之间、相邻于所述上端的喉部密封件。
