詳細介紹
ZJ型渣漿泵,耐磨渣漿泵技術(shù)參數(shù):
口徑 : 40-350(mm)
流量 : 4.5-2339(m3/h)
揚程 : 6.0-133(m)
ZJ型渣漿泵,耐磨渣漿泵型號意義:
產(chǎn)品特點:
ZJ型為單級、單吸、懸臂臥式離心渣漿泵,該系列泵采用上*進的固液兩相流理論,按zui小損失原則設(shè)計。其過流部件的幾何形狀符合介質(zhì)的流動狀態(tài),減少了渦流和撞擊等局部與沿程水力損失,從而減輕了過流部件的磨損,提高了水力效率,降低了運行噪音和振動;該系列泵過流部件采用高硬合金鑄鐵,其材質(zhì)具有高抗磨性、抗腐蝕性、抗沖擊性能、從而使其壽命提高,此外,該系列泵采用動力降壓,保證了漿體不易泄露。
ZJ型渣漿泵,耐磨渣漿泵適用范圍:
ZJ型渣漿泵可廣泛應(yīng)用于電力、冶金、煤炭、建材、化工等行業(yè), 輸送含有固體顆粒的磨蝕性和腐蝕性漿體. 其固液混合物zui大重量濃度:灰漿45%、礦漿60%。該系列渣漿泵規(guī)格齊全,可采用直聯(lián)、皮帶、液力、變頻調(diào)速等傳動形式,亦可根據(jù)用戶需要串聯(lián)或并聯(lián)進行。
