Abstract

本实用新型属于柱塞泵内的一种柱塞。它主要将柱塞体制成空心筒,并在空心筒下端的侧壁上开有散热孔。由于空心筒采用冲压技术一次成型,中间无焊接,故本实用新型强度高,不易断裂、泄漏;具有散热快,结构简单,成本低等优点。

Description

柱塞
本实用新型涉及一种柱塞泵的配件,特别是装配在柱塞泵缸筒内的柱塞。
现有的柱塞一般为实芯体,所用材料大,成本高,特别是磨损后的柱塞往往要整体更换,造成材料浪费。为此,中国专利局1999年1月17日公告的专利号为ZL97235279.1,名称为“柱塞”的专利;该专利技术将柱塞制成柱塞套,且与装在其两端的连接头和闷盖通过连接杆组成一体,故更换时只需替换柱塞套即可,节约了原材料。但不易散热,柱塞与连接件之间强度不高。
本实用新型之目的在于提供一种既省材料、又易散热的柱塞。
下面结合附图所示的实施例对本实用新型作进一步详细的说明。
图1是本实用新型的结构示意图。
参见图1,本实用新型柱塞采用冲压技术将柱塞体1制成空心筒2,上端封闭,下端开口;并在下端侧壁上开有二个对称的散热孔3。该孔3和空心筒2为柱塞体1作上、下或左右往复运动时产生的内热提供一个散热的通道,确保柱塞控制在一定温度之下,不受热变形。
由于空心筒2一次成型,中间无焊接,故本实用新型强度高,不易断裂、泄漏,具有散热快,结构简单,成本低等优点。
