Abstract

本实用新型公开了一种新型八柱塞轴向柱塞泵,对原有柱塞泵的缸体、柱塞、滑靴、回程盘、配油盘进行了优化。本实用新型结构新颖,工作时运转平稳且流量均匀性好,转动惯量小,减少了能源消耗。

Description

一种新型八柱塞轴向柱塞泵
技术领域
本实用新型涉及一种轴向柱塞泵,具体说是一种新型八柱塞轴向柱塞泵。 
背景技术
目前所有的CY14-1B轴向柱塞泵,柱塞数目都是七个的,高压时容易漏油且消耗能源大,在高速转动、高压的情况下容易使压力脉动变大,产生震颤现象,使泵本身的使用寿命下降。 
发明内容
本实用新型的目的在于将原有的缸体孔数目七个增加为八个,同时回程盘孔数目也相应增加到八个,通过合理安排缸体八孔分布圆的位置角度来实现最优化的设计,使新泵的噪声低且使用寿命长。 
本实用新型的技术解决方案是: 
一种新型八柱塞轴向柱塞泵,包括了缸体、柱塞、滑靴、回程盘;缸体上均匀分布着八个柱塞孔,回程盘上也相应分布着八个孔。 
本实用新型结构新颖,通过对柱塞缸体组件的优化,使柱塞泵的压力脉动减小,解决了柱塞泵在高速转动、高压情况下的压力脉动大,产生噪声响、震颤大的现象,使柱塞泵的使用寿命大大提高。 
本实用新型与传统的相比具有运转平稳、流量均匀性好、噪声低、使用寿命长的优点。 
附图说明: 
下面结合附图和实施例对本实用新型作进一步说明。 
图1是本实用新型的内部结构示意图。 
图2是本实用新型的八孔缸体分布圆示意图。 
具体实施方式: 
参照图1本实用新型的壳体13装在泵体2上,传动轴1通过轴承14装在泵体2内、缸体12装在壳体13内,配油盘3装在缸体12与泵体2之间,缸体12用花键与传动轴1联接,分布在缸体12上的八孔中有八个柱塞11,在柱塞11的球头部包锁着滑靴10;缸体12的端面止口装有外套4,中心弹簧6作用在外套4上,通过内套5、钢球9、回程盘7将滑靴10压在斜盘8上。 
参照图2可以看出本实用新型的柱塞泵缸体孔数目为八孔;而原有柱塞泵的柱塞数为七个,缸体孔数为七孔,由于改变了缸体柱塞孔的数目和缸体分布圆的位置角度,使本实用新型的泵在实际流量脉动方面远小于之前的七孔泵。且在实际工作中八柱塞泵不管是从受力、噪音还是压力脉动方面都优于原来的七柱塞泵。本实用新型实际上是对原有的CY14-1B轴向柱塞泵的优化升级。
