高压三螺杆泵为了使其加工的螺旋型面更为精确,降低运行的噪声和提高效率,还可以对其表面进行磨削,由于这种高精度磨削曲面需要特殊的数控磨床,成本很高,故目前只对特殊要求的高压三螺杆泵使用。
为了提高螺杆的性能和避免渗氮等热处理引起的变形,可对螺杆螺旋段表面进行表面涂层处理,但必须保证表面涂层有足够的均匀度。
为了确保螺杆螺旋型面具有足够的精度,以及螺杆啮合时螺旋型面之间的间隙均匀,要求在加工时螺旋导程、螺旋型面的厚度以及螺杆的两条螺旋槽深度等尺寸公差控制在一定的范围内,这些尺寸都会直接影响到泵运行的可靠性、螺杆寿命的长短和性能。
螺杆泵机械密封维护问题:
1、启动前的准备工作
(1)全面检查机械密封,以及附属装置和管线安装是否齐全,是否符合技术要求。
(2)机械密封启动前进行静压试验,检查机械密封是否有泄漏现象。若泄漏较多,应查清原因设法消除。如仍无效,则应拆卸检查并重新安装。一般静压试验压力用2~3公斤/平方厘米。
(3)按泵旋向盘车,检查是否轻快均匀。如盘车吃力或不动时,则应检查装配尺寸是否错误,安装是否合理。
2、安装与停运
(1)启动前应保持密封腔内充满液体。对于输送凝固的介质时,应用蒸气将密封腔加热使介质熔化。启动前必须盘车,以防止突然启动而造成软环碎裂。
(2)对于利用泵外封油系统的机械密封,应先启动封油系统。停车后最后停止封油系统。
3、热油泵停运后不能马上停止封油腔及端面密封的冷却水,应待端面密封处油温降到80度以下时,才可以停止冷却水,以免损坏密封零件。/3、运转
(1)泵启动后若有轻微泄漏现象,应观察一段时间。如连续运行4小时,泄漏量仍不减小,则应停泵检查。
(2)泵的操作压力应平稳,压力波动不大于1公斤/平方厘米。
(3)泵在运转中,应避免发生抽空现象,以免造成密封面干摩擦及密封破坏。
(4)密封情况要经常检查。运转中,当其泄漏超过标准时,重质油不大于5滴/分,轻质油不大于10滴/分,如2-3日内仍无好转趋势,则应停泵检查密封装置。
