液压马达工作时産生噪声的4个原因

1、因爲液压系统侵入空气时,在低压区其体积较大,当流到高压区时受压缩,体积突然缩小,而当它流入低压区时,体积突然增大,这种气泡体积的突然改变,産生“爆炸”现象,因而産生噪声,此现象通常称爲“空穴”。空气侵入液压系统是産生噪声的主要原因。解决问题的办法:常常在液压缸上设置排气装置,以便排气。另外在开车后,使执行件以快速全行程往複几次排气,也是常用的方法:

液压泵或液压马达质量不好,通常是液压传动中産生噪声的主要部分。液压泵的制造质量不好,精度不符合技术要求,压力与流量波动大,困油现象未能很好消除,密封不好,以及轴承质量差等都是造成噪声的主要原因。在使用中,由于液压泵零件磨损,间隙过大,流量不足,压力易波动,同样也会引起噪声。面对上述原因,一是选择质量好的液压泵或液压马达,二是加强维修和保养,例如若齿轮的齿形精度低,则应对研齿轮,满足接触面要求;若叶片泵有困油现象,则应修正配油盘的三角槽,消除困油;若液压泵轴向间隙过大而输油量不足,则应修理,使轴向间隙在允许范围内;若液压泵选用不对,则应更换;在工作时,液压阀的阀芯支持在弹簧上,当其频率与液压泵输油率的脉动频率或与其它振源频率相近时,会引起振动,産生噪声。这时,通过改变管路系统的固有频率,变动控制阀的位置或适当地加蓄能器,则能防振降噪。

2、溢流阀不稳定,如由于滑阀与阀孔配合不当或锥阀与阀座接触处被污物卡住、阻尼孔堵塞、弹簧歪斜或失效等使阀芯卡住或在阀孔内移动不灵,引起系统压力波动和噪声。对此,应注意清洗、疏通阴尼孔;对溢流阀进行检查,如发现有损坏,或因磨损超过规定,则应及时修理或更换。

3、换向阀调整不当,使换向阀阀芯移动太快,造成换向冲击,因而産生噪声与振动。在这种情况下,若换向阀是液压换向阀,则应调整控制油路中的节流元件,使换向平稳无冲击。

4、机械振动,如油管细长,弯头多而未加固定,在油流通过时,特别是当流速较高时,容易引起管子抖动;电动机和液压泵的旋转部分不平衡,或在安装时对中不好,或联轴节松动等,均能産生振动和噪声。对此应采取的措施有:较长油管应彼此分开,并与机床壁隔开,适当加设支承管夹;调整电动机和液压泵的安装精度;重新安装联轴节,保证同轴度小于0.1MM等。
