Abstract

一种往复式活塞泵，具有一自动喉部密封转矩夹，从而提供了一致性并使泵的使用期限延长。

Description

一种往复式活塞泵
用于泵出涂料和其它粘性物质的往复式活塞泵是大家所熟知的。一部分这种类型的泵是不能调节的，因此当它们开始泄漏时必须被重新密封。目前可调节的设计经常会出现误装配，导致转矩变化，从而使密封寿命变化。
因此本发明的目的是提供一种泵，其能很容易地被制造，并且保持制造一致性，从而使密封期限增加。
在本发明中，转矩夹由精确的琴用钢丝制成，这使得本设计钢丝直径的公差为紧公差，能重复使用无数次，不再需要外部的圆筒组件。一旦泵开始在喉部区域泄漏，其能很容易地拆除。
采用这种设计，通过使过转矩脱离平衡，而在很大程度上改进了制造一致性。利用本设计，操作者在喉部螺母上安装夹，然后将喉部螺母旋进圆柱形壳体，直至圆柱形壳体碰到夹为止，使密封挤压没有由喉部螺母引起的变化。测试表明如果泵被不适当操作。密封挤压能减少泵的使用期限至其正常使用期限的一半。
在制造过程中提供一致性的原由同样能满足最终用户重新密封时的要求。
本发明的这些目的和优点从下面结合附图的描述中将更为清楚，其中在各视图中，同样的附图标记表示同样或类似的部件。
图1是本发明的详细剖视图；
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。
图1示出了本发明，其总的标为10，并且包括一个泵杆12和圆筒14，一个定位夹16和一个喉部螺母18。在优选实施例中夹16由琴用钢丝制成，其不仅有很紧的公差(正负0.001英寸)并且是一种弹簧钢类型。特别是根据泵的尺寸，琴用钢丝的直径可以在0.095至0.138英寸之间变动。
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力矩夹可以做出各种改变和修改。

Claims (2)

1.一种往复式活塞泵，包括一圆筒、一密封组件和一用于压挤在所述圆筒内的密封组件的密封螺母，其特征在于，该活塞泵还包括一个位于所述密封螺母和所述密封组件之间的转矩夹，所述转矩夹由弹簧型材料制成，其直径尺寸公差大约为0.001英寸。
2.如权利要求1所述的往复式活塞泵，其中所述转矩夹由琴用钢丝制成。
