系統(tǒng)簡單、初投資省,但為了保證冷水機(jī)組的流量恒定,因此不能充分利用輸送管網(wǎng)中的水流量減少所帶來的輸送能耗降低的好處。雙級泵水系統(tǒng)中把冷凍水系統(tǒng)分成冷凍水制備和冷凍水輸送兩部分。冷、熱源側(cè)和負(fù)荷側(cè)分別設(shè)置循環(huán)水泵,可以實(shí)現(xiàn)負(fù)荷側(cè)水泵變流量運(yùn)行。雙吸是指泵的方式,從葉輪的兩端進(jìn)水,叫雙吸首先,方式不同雙吸泵主要是介質(zhì)在葉輪兩端,葉輪兩側(cè)各有一個(gè)密封腔而不是泵有兩個(gè)口。
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(固體顆粒≤80mg/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。對于填料密封,有足夠的空間用于更換填料。jdhuiquan7.17

立式安裝可以減少占地面積。雙吸泵就是有兩個(gè)吸水室,水從兩邊進(jìn)來,所以造就了它的大流量。一般的泵都是從一處進(jìn)水,這也就是說明了單吸泵和雙吸泵的區(qū)別,單吸泵的流量比較小。雙吸泵一般用在清水比較多點(diǎn),清水離心泵的口和吐出口都是在水泵的中心軸線的下方,水平方向和軸線是垂直的、泵殼中開。
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.
