DAIKIN紧凑型单级叶片泵详细参数
叶片泵对油中的污物很敏感,工作可靠性较差,
油液不清会使叶片卡死,因此必须注意油液良好过滤和环境清洁。
3.因泵的叶片有安装倾角,故转子只允许单向旋转,
不应反向使用,否则会使叶片折断。
Contains pressure adjustment mechanism, the system can not adjust the valve and apply a direct motor, easy assembly.
In order to make the vane pump reliable oil, the speed must be in the range of 500 ~ 1500r / min, the speed is too low,
The blade can not press the inner surface of the stator and oil; speed is too high is caused by the pump "suction empty" phenomenon, the pump is not working properly.
The viscosity of the oil to use appropriate, too much viscosity, oil resistance increases; oil is too thin, the gap effect,
Vacuum is not enough, will cause adverse effects on oil absorption.
变量叶片泵中,当叶片处于压油区时,叶片底部通压力油,
当叶片处于吸油区时,叶片底部通吸油腔,这样,
叶片的顶部和底部的液压力基本平衡,
这就避免了定量叶片泵在吸油区定子内表面严重磨损的问题.
如果在吸油腔叶片底部仍通压力油,
叶片顶部就会给定子内表面以较大的摩擦力,以致减弱了压力反馈的作用
当转子在电动机驱动下按图示箭头方向旋转时,叶片经定子下半部时,
在离心力的作用下,从叶片槽中伸出,两叶片间的密封容积增大,
实现吸油;叶片经定子上半部时,被定子内表面逐渐压入叶片槽内,
密封容积减少,实现压油。泵的转子每转一转,每个密封容积吸、压油各一次。
改变定子和转子间的偏心量,便可改变泵的排量,故称为变量叶片泵。
运转平衡安静,特别适合机床和室内的要求。
