HFM系列后吸式耐腐耐磨压滤泵的特色在于:结构独特;密封寿命长于同类泵1~2倍,尤其是带压输送岗位(压滤机配用或带压喷淋循环泵),密封优势尤其明显;高压力的工况下,耐磨性优于常规泵。因为双级加压,料浆泵的叶轮线速度在22~28米/秒之间,即可获得0.8~1MPa的出口压力,而同类单级料浆泵的叶轮线速度在35~40米/秒左右,才能获得0.8~1MPa的出口压力。叶轮线速度下降,同工况下耐磨性能成几何倍数提高。该泵投放市场后,极受用户欢迎,已快速覆盖有色冶炼、环保、化工、钛白粉、非金属矿加工等行业。适用于输送100℃以内的腐蚀性清液或料浆。
一、适用范围
1. 本系列泵可输送100℃温度以内的各类腐蚀性和非腐蚀性清液和料浆或用作各类压滤机加压喂料用泵,例如:有色金属的锌、铜、钴、镍、锰等湿法冶炼工艺的压滤机配用泵或工艺流程泵,矿山选矿、非金属矿产加工(钛白粉、高岭土等)工艺中的浆体输送泵,环保产业中的污泥、废渣输送泵,其它化工、染料、制药、食品生产工艺中的压滤泵或压力输送泵。
2. 长期逼压运行(泵出口压力高)输送腐蚀性介质的岗位,如烟气脱硫、大气治理中的压力喷淋泵、压力冲洗泵等。
3. 其它泵输送介质时,容易泄漏的岗位。
4. 该泵有单级和双级二个系列,能满足需要小流量高压力输送腐蚀性料浆的岗位。
不适用岗位:吸入口液体液位低于泵位置0.5m以下或吸入口负压过大的岗位。
二、过流材料的选定
默认为改性超高分子量聚乙烯:适用于100℃以内的腐蚀性、磨蚀性料浆的输送。
耐腐耐磨不锈钢(B):适用于110℃以内的磨蚀性料浆的输送。例如用于电解锌、电解锰等高温浸出的工序中的高温浆体的输送,效果会更好。
聚丙烯(P):用于无固相物料的清液的输送。例如废气处理系统的逼压喷淋泵(烟气脱硫等)。
氟塑料(F):主要适用输送带溶剂的介质和强氧化性介质,例如浓硝酸等。
聚氨脂橡胶(PU):主要适用于腐蚀性要求低,而磨蚀性严重的岗位,如排渣泵,或选矿中的旋流器配用泵。
