中開(kāi)泵廣泛地應(yīng)用在石油、化工、電力冶金、礦山、選船、輕工、農(nóng)業(yè)、民用和國(guó)防各部門(mén),在國(guó)民經(jīng)濟(jì)中占有重要的地位。中開(kāi)泵的流量調(diào)節(jié)到合理的狀態(tài),這個(gè)是非常有必要的那么我們一般是怎樣操作的呢?出口閥開(kāi)度調(diào)節(jié)這種方法中泵與出口管路調(diào)節(jié)閥串聯(lián),它的實(shí)際效果如同采用了新的泵系統(tǒng)。旁路閥調(diào)節(jié)這種方法中閥門(mén)和泵并聯(lián),它的實(shí)際效果如同采用了新的泵系統(tǒng),泵的輸出壓頭發(fā)生改變。調(diào)速控制葉輪轉(zhuǎn)速變化直接改變泵的流量曲線,曲線的特性不發(fā)生變化,轉(zhuǎn)速降低時(shí),曲線變的扁平,壓頭和流量均減小。調(diào)整葉輪直徑這種方法不使用任何外部組件,流量特性曲線隨直徑變化而變化。為提高中開(kāi)泵的沖夭爐熔化能力,增大爐膛尺寸(熔化帶)。
運(yùn)行數(shù)據(jù):出口直徑:DN=80~800mm流量:50~11600m3/h(額定點(diǎn))揚(yáng)程:H=7.6~200m(額定點(diǎn))許用工作壓力:≤2.5MPa許用試驗(yàn)壓力:≤3.75MPa介質(zhì):清水或物理化學(xué)性質(zhì)類(lèi)似于清水的其它液體(固體顆?!?0mg/L)。溫度:≤105°C水力經(jīng)優(yōu)化設(shè)計(jì)三水力模型,不僅使泵具有優(yōu)異的水力性能,并且沒(méi)有軸向力(理論上)這一困擾水泵特別是大型水泵運(yùn)行的難題。泵體、泵蓋、葉輪經(jīng)精密鑄造,過(guò)流表面光滑提高了泵的抗汽蝕性能和效率。密封根據(jù)輸送介質(zhì)或用戶要求采用填料密封或機(jī)械密封,不受轉(zhuǎn)向限制。對(duì)于填料密封,有足夠的空間用于更換填料。jdhuiquan6.21

采用沖天爐爐缸噴氧新技術(shù),提高熔化率和鐵液溫度,使熔化速度達(dá)6一6.5t/h,出爐溫度在1450℃以上。同時(shí)為加大前爐儲(chǔ)存鐵液的容量,對(duì)前爐進(jìn)行改造,在原出值口正上方,前爐頂部增設(shè)出渣口(即雙排渣口前爐,_七排渣口與過(guò)橋齊平).容達(dá)到5.5一6t,球鐵鐵液化學(xué)成分控制如下:3.3%-3.8%C,2.5%一2.8%Siyc,Mn<0.5%,P<0.06%,RE。管道中開(kāi)泵經(jīng)緩沖鑄、流量計(jì)送至均壓罐,再經(jīng)3只分管路、減壓器、電磁閥、止回閥、膠管和氧總成,經(jīng)爐缸區(qū)專(zhuān)用風(fēng)口將氧氣直接吹人缸內(nèi),從而提高了加氧效率。在中開(kāi)泵的地面驅(qū)動(dòng)裝置方面,盡管進(jìn)行了多種設(shè)計(jì)方案優(yōu)化,但平行軸式地面驅(qū)動(dòng)裝置由于電動(dòng)機(jī)軸和減速器輸出軸之間仍存在著中心距。
工作條件:1. The allowable working pressure is 2.5MPa, that is, the pump inlet pressure + pump lift ≤2.5MPa. According to the maximum pressure under the pump shell, the pump body and pump cover material using gray cast iron (1.6MPa), Ductile iron (2.0MPa), cast steel (2.5MPa). Please indicate the pressure of the pump or the material at the time of ordering.
2. Media: Water with a temperature of ≤105°C or other liquids of physicochemical properties similar to water (solid particles ≤80mg/L). Bearing 1, the use of grease lubrication of closed rolling bearings, simple maintenance, long running time, 2, equipped with a constant oil level oil cup, can also be used dilute oil lubrication;
3, the selection of imported (SKF, NSK, NTN) high-quality bearings, smooth operation, low noise, long service life. Compact structure and good stability.
S, SA series double suction medium open pump for the pump shell open structure, import and export are in the pump body, maintenance only need to hoist the pump cover, rotor parts can be removed for maintenance operations, without the need to disassemble the pipeline, very convenient. According to the need of electric motor (drive) can also be on the left side at the right end, convenient for on-site installation. The structure shortens the axial size of the rotor parts, the steel of the shaft is better, and the operation is more stable and reliable. Equipped with pump body seal ring, and impeller seal ring for optional parts. The sealing ring can be replaced after wear, reducing operating and maintenance costs.
