Abstract

灌注活塞往复泵(10)具有活塞引导件(14)，该活塞引导件(14) 环绕活塞(16)，且设有在引导件(14)上端内径中的轴承构件(22)。轴承(22)由25％的碳填充的PTFE形成，且可不用工具而安装到上述ID中。该轴承(22)容许在轴承(22)与活塞(16)之间使用可以忽略的间隙。

Description

活塞密封件引导轴承
技术领域
本申请请求获得2007年8月30日提交的序列号为60/969,070的美国申请的权益，该申请的内容通过引用并入本文中。
背景技术
众所周知，灌注(priming)活塞往复泵用于泵送高粘度流体，如密封剂和粘合剂。此类泵通常具有约0.020英寸的活塞引导件与活塞之间的金属到金属的间隙。大的缝隙容许活塞引导件和活塞座左右摇摆，且不均匀和过早地磨损，同时这种磨损会增大缝隙，这继而又导致更大的磨损。
发明内容
因此，本发明的目的在于提供一种灌注活塞泵，其减小活塞密封件的磨损，延长活塞密封件的使用寿命，以及减小活塞引导件中的磨损。
该活塞引导件设有位于引导件的上端(在正常方向上)的内径中的轴承构件。轴承由25％的碳填充的PTFE形成，且可不用工具而安装到上述ID中。此类轴承容许在轴承与活塞之间使用可以忽略的间隙，从而使得如所期望地减小磨损。
通过结合附图的如下说明，将更为完全地明白本发明的这些及其它目的和优点，其中在所有多个视图中，相同的附图标记表示相同或相似的零件。
附图说明
图1为灌注活塞泵的截面图。
图2为利用本发明的活塞引导组件的详细截面图。
具体实施方式
图1中示出了灌注活塞往复泵10。杆件12具有活塞16，该活塞16通过螺纹固定到杆件12的下端(朝图中的右侧)。活塞引导件14环绕活塞16，且设有在引导件14的上端(在正常方向上)的内径中的轴承构件22。轴承22由25％的碳填充的PTFE形成，且可不用工具而安装到上述ID中。该轴承22容许在轴承22与活塞16之间使用可以忽略的间隙。活塞密封件24为此类已知泵的一部分，且位于引导组件14下端的OD上。
可在不偏离由如所附权利要求所限定的本发明的精神和范围的情况下对活塞引导组件进行各种变化和修改。

Claims (2)

1.一种灌注活塞往复泵(10)，包括：
杆件(12)；
活塞(16)；
环绕所述活塞(16)的活塞引导件(14)，所述引导件(14)具有内径、外径、下端和上端，所述下端是所述引导件(14)的远离所述杆件(12)的端部，所述上端是所述引导件(14)的靠近所述杆件(12)的端部；
活塞密封件(24)，位于所述引导件(14)的下端的外径上，
其特征在于包括位于所述引导件(14)的上端的所述内径中的轴承构件(22)。
2.根据权利要求1所述的泵(10)，其中所述轴承构件(22)由25％的碳填充的PTFE形成。
