方便現(xiàn)場安裝。(1)結(jié)構(gòu)上縮短轉(zhuǎn)子部件軸向尺寸，軸的鋼性更好，運行更穩(wěn)定可靠。設(shè)有泵體字符封環(huán)，而葉輪密封環(huán)為可選用件。密封環(huán)磨損后可以更換，減少了運行維護費用。S系列中開泵裝配與拆卸1，裝配轉(zhuǎn)子部件：依次將葉輪，軸套，軸套螺母，填料套，填料環(huán)，填料壓蓋，擋水圈，軸承部件裝在泵軸上，并套上雙吸密封環(huán)，然后裝上聯(lián)軸器。將轉(zhuǎn)子部件裝在泵體上，調(diào)整葉輪的軸向位暈到兩側(cè)雙吸密封環(huán)的中間加以固定，將軸承體壓蓋同固定螺釘緊固。裝上填料，放好中開面紙墊，蓋上泵蓋打緊螺尾柱銷后，擰緊泵蓋螺母，zui后裝上墳料壓蓋。但不要將填料壓得太緊，填料過緊會使軸套發(fā)熱，耗費功率較大，也不要壓得太松，過松會使液體滲漏大，水泵效率降低。
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(固體顆粒≤80mg/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。jdhuiquan4.13

In order to achieve the purpose of sealing, while the dynamic ring and static ring has a lubrication effect. The medium-open pump is regularly inspected during operation. The characteristics of the use of mechanical seals in medium-open pumps 1, the main advantage of the mechanical seal of the medium open pump is that the seal is reliable in a long life cycle, the leakage is very few, the effect is long, generally can use about 5 years, the maintenance cycle is long. However, the mechanical seal structure is complex, the manufacturing and installation precision is high, the lattice is high, the technical request to the maintenance personnel is high. Therefore, it is very important to ensure the reliable operation of mechanical seals and extend the service life of mechanical seals. Of course, the price sealed with seasoning is cheap, the technical requirements are relatively low. The problem that the mechanical seal of medium open pump is easy to occur in the process of use, the main problem that the mechanical seal is easy to occur is the leakage amount is very poor and the temperature is too high. Touch the mechanical seal cover with your hand, and if you can't stay on it, it means the temperature is too high. Leakage per side should not exceed 60 drops of/min, if linear flow, it indicates that the amount of leakage is too large, can determine whether to observe the operation;
產(chǎn)品概述：S、SA系列雙吸中開泵，主要供輸送溫度不高于105°C的清水或理化性質(zhì)類似于水的液體。適用于自來水廠、泵站、電站、空調(diào)循環(huán)用水、采暖用熱水循環(huán)、工業(yè)供水系統(tǒng)、消防系統(tǒng)、船舶、煉油工業(yè)(一般性液體)等輸送液體的場合。
產(chǎn)品特點：
1、內(nèi)置式密封潤滑結(jié)構(gòu)：泵內(nèi)置式密封潤滑結(jié)構(gòu)，密封循環(huán)水對泵密封系統(tǒng)的潤滑、沖洗更為直接、有效。
2、外形美觀：直線型的外觀并在泵蓋上附加強筋，內(nèi)置式密封潤滑結(jié)構(gòu)使泵整體結(jié)構(gòu)渾然一體，靈活的結(jié)構(gòu)設(shè)計使泵更加精美大方。
3、率：采用CFD計算流體動力學(xué)，分析計算出泵內(nèi)壓力分布和速度分布關(guān)系、優(yōu)化泵的流道設(shè)計，確保泵有的水力形線，提高了泵的效率。泵體采用雙流道設(shè)計，以減小徑向力。泵體、泵蓋、葉輪等過流部采用樹脂砂板模造型，保證了外觀及流道尺寸以及泵的水力效率。S、SA系列雙吸中開泵效率比一般雙吸泵高3～5％。
4、平衡精度高：轉(zhuǎn)子部件動平衡精度為G1。0級。
5、軸：軸短且剛性好，增加軸徑，以延長軸承和機械密封的使用壽命。軸為全封結(jié)構(gòu)，確保了不與介質(zhì)接觸，不銹蝕，使用壽命長。
6、雙蝸殼：高揚程泵采用雙蝸殼結(jié)構(gòu)，減輕了徑向力。

To bring it into line with the principles of economy, safety and application. The reliable operation of the medium-open pump determines the normal operation of the industrial production system, we can also assist in the operation of the pump in a series of things. In the operation of the medium-open pump by perbance differentiation into three data, small flow and high lift, medium flow and medium lift, large flow and large lift. It should be noted that in these three kinds of perbance, to avoid the pump long-term operation under small flow and large lift, so that the pump will produce a vortex, vortex will produce a large thrust, so that the shaft bending deflection is too large, not conducive to continuous operation. In the rotating component lubrication efforts, the rotary components of the pump have bearings, shafts and other bs, to ensure their lubrication, regular inspection of lubricants, check the amount of oil, oil can not be too little, not too much, oil quality is also very important, when the oil spoilage to be replaced in a timely manner. The pump group for planning management, the operation of the pump and maintenance of the installation rules and regulations, so that the temperature is not exceeded, the speed of operation is not speeding.
