螺杆泵应用于液压电梯
从市场上螺杆泵的销售情况来看,其大多数还是用于液压电梯。采用螺杆泵的液压电梯,分为用油缸直接将电梯轿箱推上和通过滑轮间接地推轿箱两种方式。作为液压设备用,油泵的排出压力为2.9~4.9MPa、排量为3001/min,上述参数范围的油泵采用较多。
由于要求减小轿箱的振动,使其与建筑物具有同等的使用寿命,所以建筑物的载人电梯几乎都采用螺杆泵。欧美一些国家多采用油浸式,即把电功机和油泵设置在油箱内,而日本则主要考虑效率和维护问题,故采用带式驱劝型。
决定电梯的乘坐舒适度灼因素之一是泵的排出压力脉动。螺杆泵内形成的密封腔在泵的排出端,泵回转1周密封腔启开2次,所以脉功一26图3排出压力脉动波形实例的基本频率是泵转速的2倍。启开处的密封腔压力与排出压力的压差较小,但为了进一步减小脉动值,还需想些办法,使排出压力接近启开处压力。
另外,由于泵与电动机的对中心不良、螺杆弯曲、二条螺旋槽深度存在误差等原因,有时会产生基本频率是泵转速1倍的脉动,及由于从动螺杆在螺杆衬套内摆动,有时会产生基本频率是泵转速1/2的脉动。
特别是后一种情况更容易发生,但当排出压力一升高,这种情况也就不存在了。
