雙吸泵主要是葉輪兩端，長(zhǎng)處主要是抗汽蝕能力比單吸泵強(qiáng)，平衡軸向推力作用比單吸泵好，運(yùn)行起來(lái)更平穩(wěn)由于雙吸泵的口和排出口均在泵軸心線下方，雙吸泵的葉輪相當(dāng)于兩個(gè)相同大小的單吸葉輪組合在一起工作，在和單級(jí)離心泵葉輪一樣大小直徑的情況下流量可以翻一倍；這就是為什么叫雙吸泵的原因。雙吸泵泵體就是有兩個(gè)吸水室，特別之處主要還是雙吸葉輪的進(jìn)水方向與單吸葉輪不一樣。
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。jdhuiquan7.17

水在流動(dòng)過(guò)程中所消耗的能量(水頭損失)就是用來(lái)克服內(nèi)摩擦力和水與設(shè)備界面的摩擦力。如果泵、葉輪表面光滑(這種表面稱為水力光滑表面)表面阻力較小。消耗能量就小，在水泵過(guò)流面和葉輪上噴涂高分子復(fù)合材料，使其表面形成水力光滑表面，超光滑表面涂層表面光潔度是經(jīng)過(guò)拋光后不銹鋼的20倍。
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.
