軸承間距較短,從而減小了軸的撓度,延長了機械密封和軸承的壽命。軸套可以采用多種不同的材料,以防止軸被腐蝕和磨損,軸套可更換。磨損環(huán)泵體與葉輪間采用可更換的磨損環(huán),防止泵體和葉輪的磨損,更換方便,維修費用低,同時保證運行間隙和較高的工作效率。
運行數(shù)據(jù):出口直徑:DN=80~800mm流量:50~11600m3/h(額定點)揚程:H=7.6~200m(額定點)許用工作壓力:≤2.5MPa許用試驗壓力:≤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)計三水力模型,不僅使泵具有優(yōu)異的水力性能,并且沒有軸向力(理論上)這一困擾水泵特別是大型水泵運行的難題。泵體、泵蓋、葉輪經(jīng)精密鑄造,過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械密封,不受轉(zhuǎn)向限制。對于填料密封,有足夠的空間用于更換填料。jdhuiquan7.17

雙作用水環(huán)泵比單作用水環(huán)泵大大減少尺寸和重量。由于工作腔對稱分布于泵輪轂兩側(cè),改善了作用在轉(zhuǎn)子上的載荷。此種泵的抽速較大,效率也較高,但極限真空較低(3)雙級水環(huán)泵:雙級水環(huán)泵大多是單作用泵串聯(lián)而成。實質(zhì)上是兩個單級單作用的水環(huán)泵的葉輪共用一根心軸聯(lián)接而成。
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.

雙吸泵的抗氣蝕能力比單吸泵要強由于介質(zhì)在葉輪兩端,會形成水力對稱這樣雙吸泵的平衡軸向推力作用比單吸泵要好,運行起來更平穩(wěn)而且介質(zhì)的流速較低,葉輪不容易產(chǎn)生氣蝕現(xiàn)象。但是雙吸泵比單吸泵要多一個密封腔,所以其成本相對較高,其次,輸送流量要求不同雙吸泵更適合輸送大流量。
