意大利赛特玛SETTIMA低或无噪音泵
中级会员第7年
代理商液压泵(尤其是高压液压泵)发出的噪音和/或震动达到了某些新应用环境难以接受的程度。这就是为什么 Settima 要设计能够消除噪音排放的新一代齿轮泵的主要原因。
影响液压设备噪音排放的参数:
- 气蚀
- 流体从齿轮齿之间通过时产生的压力峰值
- 波动或流量脉动
Continuum®(低噪音齿轮泵)能够消除这些引起噪音的因素。
无噪音 CONTINUUM® 理念
zuan利(多项已获批或正待批准的zuan利):
- 转子外形
- 螺距
- 内力平衡
专门研究出的转子外形确保不会影响流体的体积(没有封装室)。
Continuum® 转子外形的螺旋体(转子之间只有一个接触点)确保平缓地输送流体,使脉动小化。内部安装了静液压机构,避免影响效率。
创新的内部结构
脉动是有害的
- 在软管和管道设计中,压力脉动重要的;因为压力脉动影响液压系统的使用寿命。
- 噪音不仅是由泵机自身产生的,在很多情况下,随着脉动增强系统也会产生噪音。随之而来的压降在显著消耗能量的同时,还会降低总效率。
Continuum® 泵是避免系统脉动引起的各类问题的理想选择。内部转子的特殊设计消除了气蚀和脉动,确保泵机和系统无噪音,使用寿命长,同时降低了能量损失。
CONTINUUM® 容积效率
Continuum® 泵的容积效率取决于压力和速度。Continuum® 泵实现了较高的容积效率。
