帆船的泥浆泵填料函
填料函
开发离心泵时,需要防止泵送物通过泵壳背面和转动叶轮的旋转轴之间的开放间隙倒出。这是通过将绳状材料(称为填料)填充到外壳后部的圆柱形开口中来实现的,轴从中穿过。填料的横截面通常为 1/4”、3/8” 或 1/2” 方形,其尺寸与轴外径和填料函内径之间的环形截面相匹配。它以线圈形式出现,并被切割成适合轴外径。它是一种柔软的材料,通常含有润滑剂。开口,即填料函,在底部或“喉咙”(最靠近叶轮的内侧端)有一个肩部,并在外侧端装有一个称为压盖的从动件,它将填料压缩到填料函的内侧,紧靠填料函底部的台肩和旋转的泵轴。这有效地限制了泵的泄漏。它不会完全防止泄漏。为了冷却和润滑填料,必须从泵中泄漏少量泵送物。
