上海龙亚水泵与您一起探讨提高卧式多级离心泵效率的方法
目前来说，高效能的泵才会更受到市场的青睐！据悉，广泛应用于工厂、石油、化工等行业的泵类产品，因其不同程度地存在耗能高、效益低等不足，严重制约着企业经济效益的提高。高效的卧式多级离心泵，才会更有市场。因为此类泵浦属于小流量、高扬程泵，与目前广泛应用于工矿企业、石油化工等行业的泵类产品相比，具有更加高效节能、可靠性较高、结构紧凑、检修方便等特点，才能获得很好的经济效益。今天我们来讨论一下怎么样才能提高卧式多级离心泵的效率。
合理确定钛龙卧式多级离心泵的管径，缩短卧式多级离心泵管道长度，减少管道附件，杜绝“高炮”外流，而其适用范围也能够扩展到矿山、钢铁、电力等行业。
1.卧式多级离心泵管径的合理确定影响泵站的效率。实践证明，管径过大或过小都是不经济的。在管道长度和流量不变的情况下，如果管径大，流量小，水头损失小，耗电量小，但管道投资高。如果管径小，情况与上面相反。为了减少管道损失，应合理确定VAREM卧式多级离心泵进出口管道的直径。如果已经投入使用的管径太小，管道的水头损失就会增加。为了提高管道的效率，根据经济管径考虑更换管道。
2.消除“高射炮”外流。所谓“高射炮”外流，是出口池水面以上的卧式多级离心泵出口处的自由(射流)外流。这种排放方式人为提高了卧式多级离心泵的实际扬程，泵的工作点向左上移动，从而降低了泵的流量和效率。同时，由于出水池的无序流动，使池(厂)内水头损失和出水建筑物(或构筑物)长度增加。为了增加出水量，提高钛龙水泵效率，降低能耗，水泵出水管应安装在出水建筑物(或构筑物)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。为防止停堆期间出水池中的水倒流，提供了破坏虹吸真空的设施。在虹吸管上升段对应出水池设计水位标高处可安装一根通气管。泵停止时，由于水在重力作用下迅速排出，在该处形成真空，空气通过管道吸入，虹吸管损坏。通气管的截面积一般为出水管截面积的5 ~ 8%。
3.缩短ZILMET卧式多级离心泵的管道长度。进出水管的长度应尽可能缩短。但当水源与出水池之间地形平坦时，缩短管道必然会增加引水渠、进水池和泵房的开挖量，或者增加出水池和主渠道的填筑工程量。将小型泵站的水平安装改为倾斜安装，或将泵下行井或半下行井安装，将管道折线布置改为直线布置，可以缩短泵房内管道的长度，节省弯头，降低水头损失。根据情况提高管道内壁的光滑度，可以减少管道的阻力损失。一般来说，高扬程离心泵的泵送装置主要是减少沿途阻力。
4.降低管道附件的局部阻力系数，造成卧式多级离心泵水头损失大，运行时消耗大量能量。因此，应尽量减少不必要的内部管道附件。底阀在管道附件中阻力系数最大，应取消，换成其他注水设备和截断设施。根据相关数据，底阀的能量损失占水管总能量损失的50% ~ 70%，占进出水管总能量损失的10% ~ 50%。上海龙亚泵阀销售电话:400-001-5655。上海龙亚泵阀，材质好，皮实耐用！每一个泵都是一个承诺！上海龙亚泵阀品牌服务承诺:在质量保证期内，我厂负责免费维修和更换缺陷产品，并在24小时内回复所有质量投诉。应派遣服务人员离开现场，不排除故障或做出结论。本厂生产的配件均为原装配件。我厂生产的产品及配件，一般都是原厂配套的。如有安装尺寸和质量问题，我们将无条件退换，所有设备终身服务！(整机保修一年，易损件除外)。泵站扬程越低，底阀能量损失比例越大。此外，底阀的存在也给运营管理带来了很多麻烦，因此，早就有人提出取消底阀。目前，一些泵站取消了底阀，采用真空泵注水，取得了良好的节能效果。然而，底阀在小型泵送设备中仍然普遍存在，这是其效率低的原因之一。为了减少管道进出口的水头损失，可以在管道入口处增加一个喇叭口。对于倾斜管道，进口可安装平切管或专用扩口管，管道出口可使用扩散管，节能效果显著。

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 products and accessories produced by our factory are generally supplied by the original factory. If there are installation size and quality problems, we will return unconditionally, all equipment life-long service! (the whole machine is guaranteed for one year, except for wearing parts). 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.
