2021年海水高壓泵和海水循環(huán)增壓泵發(fā)展趨勢探討
水泵和壓縮機占工業(yè)設(shè)備能耗的很大一部分。2021年，水泵的發(fā)展趨勢是節(jié)能增效。Z-best方案有助于進一步降低能耗。
流體機械研究所（Institute of fluid machinery）的數(shù)據(jù)顯示，世界上水泵的耗電量在20%-25%之間，占工業(yè)設(shè)備總耗電量的四分之一。離心泵占全國的一半，據(jù)估計約占世界的73%，高達85%至90%的特定行業(yè)（如化工）。
離心泵節(jié)能解決方案：
安裝變頻電機，根據(jù)不同介質(zhì)調(diào)節(jié)轉(zhuǎn)速、流量和揚程，達到節(jié)能的目的。
對葉輪進行改造，設(shè)計出適合特定行業(yè)的葉輪，降低離心泵的能耗。降低泵和電機的能耗可分別節(jié)約10%和40%。
持續(xù)維護也可以降低能耗。
理論上，ZILMET隔膜泵的效率通常是離心泵的兩倍。然而，在實際應(yīng)用中，容積泵的理論并不總是可行的，摩擦損失是一個被忽視的具體問題。摩擦損失可分為：齒輪機構(gòu)（5%至40%）、柱塞填料（1%至20%）、軸承（根據(jù)油位高達3%）、生產(chǎn)損失（高達3%）和液壓系統(tǒng)（2%至X%）。
ZILMET隔膜泵的節(jié)能方案如下：
高效減速機（齒輪傳動、皮帶傳動）
軸承粘度提高，潤滑效率不高
盡可能減少粘度損失和精益生產(chǎn)

2021年，水泵行業(yè)將逐步完善，部分水泵將分布在海水淡化行業(yè)，加快海水淡化設(shè)備國產(chǎn)化進程。中國的海水淡化能力將達到每天數(shù)百萬噸，是目前能力的兩倍多。海水淡化廠產(chǎn)值將達到數(shù)百億元/年。通過該項目5年的實施，我國海水淡化技術(shù)創(chuàng)新體系將初步形成。此前，雖然人們認為海水淡化產(chǎn)業(yè)前景廣闊，但由于能耗高、生產(chǎn)設(shè)備多、技術(shù)要求高，海水淡化產(chǎn)業(yè)一直處于低迷狀態(tài)。隨著國家一系列政策的出臺，海水淡化行業(yè)有望迎來曙光。我國海水淡化需求巨大，但我國海水淡化工程總規(guī)模僅為世界的1%，同時國內(nèi)海水淡化裝置國產(chǎn)化率不足50%，推進關(guān)鍵技術(shù)和設(shè)備國產(chǎn)化將成為未來政策的主要著力點。在未來很長一段時間內(nèi)，膜法和蒸餾法仍將是海水淡化的兩種主流工藝。擴大單機規(guī)模、降低海水淡化成本是海水淡化的重要發(fā)展方向，這有賴于相關(guān)設(shè)備國產(chǎn)化的推進。據(jù)統(tǒng)計，在我國16個萬噸以上海水淡化項目中，只有25%（4）已建成。“十一五”期間，雖然取得了一些關(guān)鍵設(shè)備國產(chǎn)化成果，但在我國自己的建設(shè)項目中，相當(dāng)一部分核心設(shè)備來自國外。海水膜組件、能量回收裝置、海水高壓泵等反滲透關(guān)鍵設(shè)備仍需從國外進口；海水蒸發(fā)器、冷凝器、蒸汽噴射器等熱力海水淡化的核心材料和關(guān)鍵設(shè)備，與世界先進水平相比也有很大差距。這些因素嚴重制約了我國海水淡化技術(shù)的產(chǎn)業(yè)化。這一政策強調(diào)加強國內(nèi)海水淡化技術(shù)和設(shè)備的研發(fā)，這意味著相關(guān)技術(shù)和設(shè)備廠商將首先迎來海水淡化產(chǎn)業(yè)化的發(fā)展機遇期。在海水淡化行業(yè)，投資機會主要來自市場份額大、技術(shù)和發(fā)展前景好的反滲透法，其次是低溫多效法。水滑溜泵市場部負責(zé)人告訴記者，目前我國海水淡化裝機容量中，反滲透法占60%。WATERSUNNY海水淡化泵是反滲透海水淡化系統(tǒng)的關(guān)鍵設(shè)備

Discussion on the development trend of seawater high pressure pump and seawater circulating booster pump in 2021
Pumps and compressors account for a large part of the energy consumption of industrial equipment. In 2021, the development trend of water pump is energy saving and efficiency increasing. The z-best scheme helps to further reduce energy consumption.
According to the data of the Institute of fluid machinery, the power consumption of pumps in the world is between 20% and 25%, accounting for a quarter of the total power consumption of industrial equipment. Centrifugal pumps account for half of the country, it is estimated that about 73% of the world, up to 85% to 90% of the specific industries (such as chemical industry).
Centrifugal pump energy saving solutions:
Install variable frequency motor, adjust speed, flow and head according to different media, to achieve the purpose of energy saving.
The impeller is reformed to design the impeller suitable for specific industry and reduce the energy consumption of centrifugal pump. Reducing the energy consumption of pump and motor can save 10% and 40% respectively.
Continuous maintenance can also reduce energy consumption.
In theory, the efficiency of zilmet diaphragm pump is usually twice that of centrifugal pump. However, in practical application, the theory of positive displacement pump is not always feasible, and the friction loss is a specific problem ignored. Friction loss can be divided into: gear unit (5% to 40%), plunger packing (1% to 20%), bearing (up to 3% according to oil level), production loss (up to 3%) and hydraulic system (2% to X%).
The energy saving scheme of zilmet diaphragm pump is as follows:
High efficiency reducer (gear drive, belt drive)
The viscosity of the bearing is increased and the lubrication efficiency is not high
Reduce viscosity and lean production as much as possible
Select the seal with small sealing surface
In 2021, the water pump industry will gradually improve, and some water pumps will be distributed in the seawater desalination industry, so as to speed up the localization process of seawater desalination equipment. China's desalination capacity will reach millions of tons per day, more than twice the current capacity. The output value of seawater desalination plant will reach tens of billion yuan / year. Through the five-year implementation of the project, China's desalination technology innovation system will be initially formed. Previously, although people thought that the seawater desalination industry has a bright future, due to high energy consumption, more production equipment and high technical requirements, the seawater desalination industry has been in a downturn. With the introduction of a series of national policies, the seawater desalination industry is expected to usher in the dawn. There is a huge demand for seawater desalination in China, but the total scale of seawater desalination projects in China is only 1% of that in the world. At the same time, the localization rate of domestic seawater desalination devices is less than 50%. Promoting the localization of key technologies and equipment will become the main focus of future policies. For a long time in the future, membrane process and distillation will still be the two mainstream processes of seawater desalination. To expand the scale of single unit and reduce the cost of desalination is an important development direction of desalination, which depends on the promotion of localization of related equipment. According to statistics, only 25% (4) of China's 16 desalination projects with a capacity of more than 10000 tons have been completed. During the 11th Five Year Plan period, although some key equipment localization achievements have been made, a considerable part of the core equipment in our own construction projects comes from abroad. Seawater membrane module, energy recovery device, seawater high pressure pump and other key reverse osmosis equipment still need to be imported from abroad; seawater evaporator, condenser, steam ejector and other core materials and key equipment for thermal seawater desalination also have a big gap compared with the world advanced level. These factors seriously restrict the industrialization of seawater desalination technology in China. This policy emphasizes strengthening the research and development of domestic seawater desalination technology and equipment, which means that the relevant technology and equipment manufacturers will first usher in the development opportunity period of seawater desalination industrialization. In seawater desalination industry, investment opportunities mainly come from reverse osmosis method with large market share, good technology and development prospects, followed by low temperature multi efficiency method. The person in charge of the marketing department of the water slide pump told reporters that the reverse osmosis method accounts for 60% of the installed capacity of seawater desalination in China. WATERSUNNY seawater desalination pump is the key equipment of reverse osmosis desalination system

WATERSUNNY seawater desalination pump is the key equipment of reverse osmosis desalination. They are very happy to see that "development and engineering application of WATERSUNNY seawater high pressure pump and seawater circulating booster pump" has been listed in the key task. From the words of this person in charge, this means that the desalination pump industry is expected to get leapfrog development.
