为除去混入油中的水份,日本前不久开发了水清除机DH系列。该系列有水份吸收型和油水分离型两种,这可根据水份混入量的多少来选择使用。水份吸收型的过滤元件是把表面水凝胶化的丙烯纤维加压成形制成的。被处理的油从元件内穿过时,水滴和纤维发生冲突,便被吸入纤维表面的水凝胶中从油中除去。吸收了水份的水凝胶因为泡胀成琼脂状使纤维直径增大,所以随着水份的吸收压力损失增大。一般过滤
In order to remove the water mixed with oil, Japan recently developed a water purifier DH series. The series of moisture absorption type and oil-water separation of two, which can be mixed according to the amount of water to choose how much to use. The moisture-absorbing filter element is formed by pressure-forming the surface hydrogelled propylene fibers. When the treated oil passes through the element, water droplets collide with the fibers and are removed from the oil by aspirating into the hydrogel on the surface of the fiber. Hydrogels that have absorbed moisture increase their diameter as they bulge into an agar, thereby increasing pressure loss as moisture is absorbed. General filtering
