QJB7.5/4-2500/2-38潛水推流器 ∅2500 P:7.5kW

QJB7.5/4-2500/2-38潛水推流器 ∅2500 P:7.5kW


江蘇杜安環保低速推流器性能說明:

潛水推流器配潛水全銅線圈電機,水平耦合安裝。潛水推流器可以上下升降,方便的移動,可以方便地卸下進行檢查或服務,而無需人員進入池子或井中。

潛水推流器為成套裝置,包括安裝系統和提升裝置。安裝系統由方鋼導桿和頂部部和底部支座等組成,可自由調整推流器的提升和下降,并可在不排空水池的情況下拆卸和安裝推流器。推流器裝在一個可在導桿上滑動的支架上作為一個整體,該支架必須能夠承受推流器的整個重量和造成的所有推力。提升裝置應為可移動式,起吊架固定裝置不可安裝在池壁上或池測工作平臺上,安裝在安裝系統頂部支座上,含專用起吊鉤、提升鏈和葫蘆。每臺推流器配備一套起吊架。

QJB7.5/4-2500/2-38潛水推流器 ∅2500 P:7.5kW


杜安環保潛水推流器配套提供電纜網套,防止推流水流的波動而引起電纜破壞。

安裝支架和提升裝置的起吊臂均為 AISI304 不銹鋼材質。提升鏈為不銹鋼 AISI304 材質。螺栓、螺母、墊片、旋轉操作手柄和地腳螺栓也被成套供應。安裝地腳螺栓必須采用化學螺栓,以保證推流器安裝系統能夠牢固而耐久的安裝,不能采用膨脹螺栓。

潛水推流器能適應市政污水的腐蝕環境。能推動污水或污泥流動,保證池底流速(距池底 300mm 為準)不小于 0.3m/s潛水推流器在全浸沒條件下連續工作。同時能適應連續運行、間歇運行(每小時較多啟動次數能達到 20 次)和長期停止狀態后恢復運行的工作狀況。

杜安潛水推流器無振動地平穩運行。所有旋轉部件(包括電機)在制造時進行動、靜平衡實驗。推流器運行維修成本低,可靠性高和無機械問題運行時間長。

完整的潛水推流器組成部分及供貨范圍(不限于此):

· 裝配完整的水下推進器(包括螺旋槳、機械密封、軸等)

· 潛水全銅線圈電機

· 低速推流器導軌及固定支架、電纜固定件、轉向及其定位裝置

· 不銹鋼304提升鏈(繩)

潛水推流器安裝方法:

潛水推流器廣泛應用于污水處理工藝的低速推流,是污水處理廠硝化、反硝化及除磷等工藝過程水體循環攪拌設備的理想選擇。潛水推流器通過安裝在池底的導桿和托架組件水平安裝在污水處理構筑物內。導桿和托架組件由導桿和托架組成,導桿上下部分別安裝在池壁和池底上,托架安裝在池底并且與導桿連接成整體。施工時,通過膨脹螺栓或預埋件將導桿和托架組件固定在構筑物基體上。安裝潛水推流器時,通過池面上的起吊系統將推流器上的滑套套入與之配套的自耦導桿中,將潛水推流器下放到托架上固定即可。當進行維護保養時,起吊系統通過自耦導桿將推流器提升到池面上。

杜安環保潛水推流器的導桿和托架組件的安裝一般都是在污水處理廠建設施工時安裝就位,但在出現污水處理系統存在污泥沉淀現象、有關污水處理設備損壞出現污泥沉淀現象、污水處理工藝改造、潛水推流器導桿和托架松動或損壞無法加固等情況時,需要增加潛水推流器進行攪拌解決污泥沉淀和滿足工藝要求。
