上海龍亞水泵與您一起探討提高臥式多級離心泵效率的方法
目前來說，高效能的泵才會更受到市場的青睞！據(jù)悉，廣泛應(yīng)用于工廠、石油、化工等行業(yè)的泵類產(chǎn)品，因其不同程度地存在耗能高、效益低等不足，嚴(yán)重制約著企業(yè)經(jīng)濟(jì)效益的提高。高效的臥式多級離心泵，才會更有市場。因為此類泵浦屬于小流量、高揚(yáng)程泵，與目前廣泛應(yīng)用于工礦企業(yè)、石油化工等行業(yè)的泵類產(chǎn)品相比，具有更加高效節(jié)能、可靠性較高、結(jié)構(gòu)緊湊、檢修方便等特點，才能獲得很好的經(jīng)濟(jì)效益。今天我們來討論一下怎么樣才能提高臥式多級離心泵的效率。
合理確定鈦龍臥式多級離心泵的管徑，縮短臥式多級離心泵管道長度，減少管道附件，杜絕“高炮”外流，而其適用范圍也能夠擴(kuò)展到礦山、鋼鐵、電力等行業(yè)。
1.臥式多級離心泵管徑的合理確定影響泵站的效率。實踐證明，管徑過大或過小都是不經(jīng)濟(jì)的。在管道長度和流量不變的情況下，如果管徑大，流量小，水頭損失小，耗電量小，但管道投資高。如果管徑小，情況與上面相反。為了減少管道損失，應(yīng)合理確定VAREM臥式多級離心泵進(jìn)出口管道的直徑。如果已經(jīng)投入使用的管徑太小，管道的水頭損失就會增加。為了提高管道的效率，根據(jù)經(jīng)濟(jì)管徑考慮更換管道。
2.消除“高射炮”外流。所謂“高射炮”外流，是出口池水面以上的臥式多級離心泵出口處的自由(射流)外流。這種排放方式人為提高了臥式多級離心泵的實際揚(yáng)程，泵的工作點向左上移動，從而降低了泵的流量和效率。同時，由于出水池的無序流動，使池(廠)內(nèi)水頭損失和出水建筑物(或構(gòu)筑物)長度增加。為了增加出水量，提高鈦龍水泵效率，降低能耗，水泵出水管應(yīng)安裝在出水建筑物(或構(gòu)筑物)的水面以下。已建成的“高炮”泵站出水口可改造成虹吸出水口。為防止停堆期間出水池中的水倒流，提供了破壞虹吸真空的設(shè)施。在虹吸管上升段對應(yīng)出水池設(shè)計水位標(biāo)高處可安裝一根通氣管。泵停止時，由于水在重力作用下迅速排出，在該處形成真空，空氣通過管道吸入，虹吸管損壞。通氣管的截面積一般為出水管截面積的5 ~ 8%。
3.縮短ZILMET臥式多級離心泵的管道長度。進(jìn)出水管的長度應(yīng)盡可能縮短。但當(dāng)水源與出水池之間地形平坦時，縮短管道必然會增加引水渠、進(jìn)水池和泵房的開挖量，或者增加出水池和主渠道的填筑工程量。將小型泵站的水平安裝改為傾斜安裝，或?qū)⒈孟滦芯�或半下行井安裝，將管道折線布置改為直線布置，可以縮短泵房內(nèi)管道的長度，節(jié)省彎頭，降低水頭損失。根據(jù)情況提高管道內(nèi)壁的光滑度，可以減少管道的阻力損失。一般來說，高揚(yáng)程離心泵的泵送裝置主要是減少沿途阻力。
4.降低管道附件的局部阻力系數(shù)，造成臥式多級離心泵水頭損失大，運行時消耗大量能量。因此，應(yīng)盡量減少不必要的內(nèi)部管道附件。底閥在管道附件中阻力系數(shù)最大，應(yīng)取消，換成其他注水設(shè)備和截斷設(shè)施。根據(jù)相關(guān)數(shù)據(jù)，底閥的能量損失占水管總能量損失的50% ~ 70%，占進(jìn)出水管總能量損失的10% ~ 50%。上海龍亞泵閥銷售電話:400-001-5655。上海龍亞泵閥，材質(zhì)好，皮實耐用！每一個泵都是一個承諾！上海龍亞泵閥品牌服務(wù)承諾:在質(zhì)量保證期內(nèi)，我廠負(fù)責(zé)免費維修和更換缺陷產(chǎn)品，并在24小時內(nèi)回復(fù)所有質(zhì)量投訴。應(yīng)派遣服務(wù)人員離開現(xiàn)場，不排除故障或做出結(jié)論。本廠生產(chǎn)的配件均為原裝配件。我廠生產(chǎn)的產(chǎn)品及配件，一般都是原廠配套的。如有安裝尺寸和質(zhì)量問題，我們將無條件退換，所有設(shè)備終身服務(wù)！(整機(jī)保修一年，易損件除外)。泵站揚(yáng)程越低，底閥能量損失比例越大。此外，底閥的存在也給運營管理帶來了很多麻煩，因此，早就有人提出取消底閥。目前，一些泵站取消了底閥，采用真空泵注水，取得了良好的節(jié)能效果。然而，底閥在小型泵送設(shè)備中仍然普遍存在，這是其效率低的原因之一。為了減少管道進(jìn)出口的水頭損失，可以在管道入口處增加一個喇叭口。對于傾斜管道，進(jìn)口可安裝平切管或?qū)Ｓ脭U(kuò)口管，管道出口可使用擴(kuò)散管，節(jié)能效果顯著。

Shanghai Longya pump will discuss with you how to improve the efficiency of horizontal multistage centrifugal pump
At present, high efficiency pumps will be more favored by the market! It is reported that the pump products widely used in factories, petroleum, chemical and other industries, due to their high energy consumption and low efficiency, seriously restrict the improvement of the economic benefits of enterprises. Efficient horizontal multi-stage centrifugal pump, will have more market. Because this kind of pump belongs to small flow and high lift pump, compared with the pump products widely used in industrial and mining enterprises, petrochemical industry and other industries, it has the characteristics of more efficient and energy saving, higher reliability, compact structure, convenient maintenance, etc., in order to obtain good economic benefits. Today we will discuss how to improve the efficiency of horizontal multistage centrifugal pump.
The pipe diameter of horizontal multi-stage centrifugal pump should be determined reasonably, the pipe length of horizontal multi-stage centrifugal pump should be shortened, the pipe accessories should be reduced, and the outflow of "anti-aircraft gun" should be eliminated. Its application scope can also be extended to mining, steel, electric power and other industries.
1. The reasonable determination of the diameter of horizontal multistage centrifugal pump affects the efficiency of the pump station. Practice has proved that too large or too small pipe diameter is uneconomic. Under the condition of constant length and flow, if the pipe diameter is large, the flow is small, the head loss is small, the power consumption is small, but the pipeline investment is high. If the pipe diameter is small, the situation is opposite to the above. In order to reduce the pipeline loss, the diameter of the inlet and outlet pipes of varem horizontal multistage centrifugal pump should be reasonably determined. If the pipe diameter is too small, the head loss will increase. In order to improve the efficiency of the pipeline, the pipeline should be replaced according to the economic diameter.
2. Eliminate the outflow of "antiaircraft gun". The so-called "antiaircraft gun" outflow is the free (jet) outflow at the outlet of horizontal multistage centrifugal pump above the water surface of the outlet pool. In this way, the actual head of the horizontal multi-stage centrifugal pump is artificially increased, and the working point of the pump moves up to the left, thus reducing the flow and efficiency of the pump. At the same time, due to the disordered flow of the outlet pool, the head loss in the pool (plant) and the length of the outlet building (or structure) increase. In order to increase the water yield, improve the efficiency of the pump and reduce the energy consumption, the outlet pipe of the pump should be installed below the water surface of the outlet building (or structure). The outlet of the built "antiaircraft gun" pumping station can be transformed into a siphon outlet. In order to prevent the backflow of water in the outlet pool during shutdown, facilities are provided to destroy the siphon vacuum. A vent pipe can be installed at the design water level elevation of the outlet pool corresponding to the rising section of the siphon. When the pump stops, the water is discharged rapidly under the action of gravity, forming a vacuum at this place, and the air is sucked in through the pipe, resulting in the damage of the siphon. The cross-sectional area of the vent pipe is generally 5 ~ 8% of the cross-sectional area of the outlet pipe.
3. Shorten the pipeline length of zilmet horizontal multistage centrifugal pump. The length of inlet and outlet pipes shall be shortened as far as possible. However, when the terrain between the water source and the outlet pool is flat, shortening the pipeline will inevitably increase the excavation amount of the diversion channel, the inlet pool and the pump room, or increase the filling amount of the outlet pool and the main channel. By changing the horizontal installation of small pump station to inclined installation, or the pump down well or semi down well installation, and changing the broken line layout of pipeline to straight line layout, the length of pipeline in pump station can be shortened, the elbow can be saved, and the head loss can be reduced. According to the situation, improving the smoothness of the inner wall of the pipeline can reduce the resistance loss of the pipeline. Generally speaking, the pumping device of high lift centrifugal pump is mainly to reduce the resistance along the way.
4. Reduce the local resistance coefficient of pipeline accessories, resulting in large head loss of horizontal multi-stage centrifugal pump, which consumes a lot of energy during operation. Therefore, unnecessary internal piping accessories should be minimized. The bottom valve has the largest resistance coefficient in the pipeline accessories, so it should be cancelled and replaced with other water injection equipment and cut-off facilities. According to the relevant data, the energy loss of the bottom valve accounts for 50% - 70% of the total energy loss of the water pipe, and 10% - 50% of the total energy loss of the inlet and outlet pipes.

The lower the pump head is, the larger the energy loss ratio of the bottom valve is. In addition, the existence of the bottom valve also brings a lot of trouble to the operation and management, therefore, it has long been proposed to cancel the bottom valve. At present, some pumping stations cancel the bottom valve and use vacuum pump to inject water, which has achieved good energy-saving effect. However, the bottom valve is still common in small pumping equipment, which is one of the reasons for its low efficiency. In order to reduce the head loss at the inlet and outlet of the pipeline, a bell mouth can be added at the inlet of the pipeline. For inclined pipeline, flat cut pipe or special flaring pipe can be installed at the inlet, and diffusion pipe can be used at the outlet of pipeline, which has remarkable energy saving effect.
