SNH66R51U12.1W2螺杆油泵结构
随着液压装置的普及,不仅要求改善作业人员的环境,而且像电梯和船用设备这类与人们居住区域有关的场所使用液压装置的情况也多起来,所以降低噪声和振动也成为社会的一大问题.为此,在设计液压装置时,噪声小,振动小则成为*的条件,这样采用液压螺杆泵的机会也增多了.
螺杆泵的结构因螺杆数不同亦有很大区别。目前,单螺杆乃至五螺杆泵均能生产。各种螺杆的形状各不相同,根据它们的特性可用于不同用途。作液压装置用的高压油泵为三螺杆泵,下面介绍三螺杆泵的结构。
三螺杆泵的结构
三螺杆泵基本上是由三根啮合的螺杆和放置螺杆的衬套构成。三螺杆泵有1根主动螺杆和2根从动螺杆,主动螺杆的螺旋槽底径与从动螺杆的外径相同,螺杆啮合时滚动接触.螺旋面的形状是螺杆横截面齿形外圆处的尖缘点滚动轨迹,设计间隙为0.01~0.O5mm,该间隙可根据螺杆泵的用途进行适当选择.
螺旋面与螺杆衬套之间形成空间,油被封闭在该空间中.主动螺杆转动时,油从吸入端被送至排出端.该密封腔沿抽向可形成数个,密封腔内的压力逐级升高,故油在排出时压力不会发生急剧变化.又因这些密封腔相互重叠,所以有一定量的油液被排到排出端.从理论上讲,排出的这些油量是稳定的。可实际上,油中含有空气,以致有可压缩比,因此排出压力会有脉动,不过该压力脉动值较小,约为排出压力的2~5%.螺杆泵的噪声和振动都比其它泵小,其噪声小于10dB(A)。
螺杆泵与齿轮泵的不同点在于:主动螺杆不驱劝从功螺杆,从动螺杆的迥转力来自排出压力,这就是说,主动螺杆不把力传递给从动螺杆,从动螺杆也能迥转。如图2所示,螺杆泵可以设计成图中(a)和与(a)相反的(b)的情况,但不管哪种场合,螺杆间的接触力都极小,这就是螺杆泵使用寿命长的原因
