水泵在管道管線上的選型配管要求

水泵在管道管線上的選型配管要求

為了提高水泵的吸入性能,管道泵吸入管路應盡可能縮短,盡量少拐彎(彎頭最好用大曲率半徑),以減少管道阻力損失。為防止泵產生汽蝕,泵吸入管路應盡可能避免積聚氣體的囊形部位,不能避免時,應在囊形部位設DN15或DN20的排氣閥。當泵的吸入管為垂直方向時,吸入管上若配置異徑管,則應配置偏心異徑管,以免形成氣···…
常規硫酸泵的材質選型

常規硫酸泵的材質選型

硫酸是強腐蝕性酸,用途非常廣泛。不同濃度和溫度的硫酸對材料的腐蝕差別較大。硫酸一般特點:沸點隨濃度升高而升高。如:濃度 5% ,其沸點為 101 ℃;濃度 50% ,其沸點為124℃;濃度 98% ,其沸點為 332℃。濃度 75%以下呈還原性(或呈中性),超過 75% 呈氧化性。.常用金屬材質表3···…
