中開泵故障發(fā)生的種類有5個方面。①由于各種原因使泵的性能（流量，揚程等）達不到生產(chǎn)上要求。（如葉輪或管堵塞汽蝕等）②由于液體的腐蝕或機械磨損所發(fā)生的故障（如軸承磨損葉輪腐蝕等）。③填料密封或機械密封損壞而發(fā)生的故障。④其他各種機械所造成的故障（如軸承安裝不當(dāng)，無游隙，溫升后燒壞，聯(lián)軸管找中不良引起振動等）。而縮短使用周期等）。中開泵所有品種維護的重點工作是相同的。必須嚴格禁止在泵體中沒有液體的時候，進行中開泵的運轉(zhuǎn)。這也是相關(guān)工作人員在操作中開泵時經(jīng)常忽略的問題。因為中開泵沒有自吸的功能，啟動中開泵設(shè)備之前，應(yīng)該首先進行泵內(nèi)是否已經(jīng)充滿介質(zhì)的確認，通常配套管線中氣體的排出，選擇灌泵的方式進行。因此。
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

Suction tank should be easy to clean before. (4) Considering the landing of the water surface, the b of the suction pipe end should have enough submerged depth to prevent the intake from the whirlpool. (5) Before installation, to carefully check whether the bottom valve is flexible, at the same time in order to facilitate inspection and maintenance, to consider a good installation b. (6) The gate valve installed on the inlet side shall be installed in a horizontal direction or tilted downwards to avoid the accumulation of air. Import Side Gate valve In addition to inspection, switching outside, must be fully open. At the same time should try not to let the air from the sealing sleeve area. (7) The bending part is as smooth as possible, reducing the number of elbows, and should try to avoid being set close to the inlet of the pump. (8) When there is a different diameter tube, in order not to allow air to accumulate, should use eccentric type of pipe. (9) For parallel operation of the pump inlet pipe, it is advisable to use a separate water inlet pipe. If the use of direct to the common mother tube, easy to occur the imbalance of import pressure. The drive (motor) drives the impeller to rotate through the pump shaft, and the blade of the impeller drives the liquid to rotate together.
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。

In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.
