隧道泵(隧道專用泵)哪家強,當然是湖南邦力機械設備有限公司,公司技術力量雄厚、生產工藝成熟、生產經驗豐富、檢測設備齊全。產品從開發、設計、研制、生產、出廠、安裝調試都有一套科學嚴密的質量管理程序。

另外,隧道專用泵的選擇,還應與脫水機類型相適應。如當釆用板框壓濾機時,其進泥過程中的壓力由低到高變化,流量由大到小變化。從目前的泵型使用情況看,離心泵應用范圍較廣,但其對輸送介質的剪切力較大。隔膜泵多用于腐性介質和加藥系統。柱塞泵價格昂貴,多用于對壓力要求非常高的債況。螺桿泵和凸輪轉子泵能夠連續、均勻地輸送介質,沒有湍流、攪動、脈動和萼切現象,特別適用于泵送濃縮污泥,最大程度地保持污泥性質,保護絮體不被破壞,從而獲得最佳的脫水效果。因此,凈水廠排泥水濃縮污泥宜采用螺杄泵或凸輪轉子泵。

一般,單泵流量在70m3/h以上,宜選擇凸輪轉子泵。單泵流量在40/h以下,宜選擇螺杄泵。當釆用螺杄泵作為進泥泵時,離心脫水機可配套單級螺杄泵,板框脫水機壓力較高的工況,宜選擇多級螺杄泵。在污泥處理系統中,凸輪轉子泵適宜輸送含固率6%以下的污泥,對于脫水污泥,一般多采用螺旋輸送機。但在特殊工況下,比如長距離、垂直高差大的工況,有壓力輸送要求或設備安裝空間小等情況下,可采用螺桿泥餅
