2021年海水高压泵和海水循环增压泵发展趋势探讨
水泵和压缩机占工业设备能耗的很大一部分。2021年，水泵的发展趋势是节能增效。Z-best方案有助于进一步降低能耗。
流体机械研究所（Institute of fluid machinery）的数据显示，世界上水泵的耗电量在20%-25%之间，占工业设备总耗电量的四分之一。离心泵占全国的一半，据估计约占世界的73%，高达85%至90%的特定行业（如化工）。
离心泵节能解决方案：
安装变频电机，根据不同介质调节转速、流量和扬程，达到节能的目的。
对叶轮进行改造，设计出适合特定行业的叶轮，降低离心泵的能耗。降低泵和电机的能耗可分别节约10%和40%。
持续维护也可以降低能耗。
理论上，ZILMET隔膜泵的效率通常是离心泵的两倍。然而，在实际应用中，容积泵的理论并不总是可行的，摩擦损失是一个被忽视的具体问题。摩擦损失可分为：齿轮机构（5%至40%）、柱塞填料（1%至20%）、轴承（根据油位高达3%）、生产损失（高达3%）和液压系统（2%至X%）。
ZILMET隔膜泵的节能方案如下：
高效减速机（齿轮传动、皮带传动）
轴承粘度提高，润滑效率不高
尽可能减少粘度损失和精益生产
选择密封面小的密封件
2021年，水泵行业将逐步完善，部分水泵将分布在海水淡化行业，加快海水淡化设备国产化进程。中国的海水淡化能力将达到每天数百万吨，是目前能力的两倍多。海水淡化厂产值将达到数百亿元/年。通过该项目5年的实施，我国海水淡化技术创新体系将初步形成。此前，虽然人们认为海水淡化产业前景广阔，但由于能耗高、生产设备多、技术要求高，海水淡化产业一直处于低迷状态。随着国家一系列政策的出台，海水淡化行业有望迎来曙光。我国海水淡化需求巨大，但我国海水淡化工程总规模仅为世界的1%，同时国内海水淡化装置国产化率不足50%，推进关键技术和设备国产化将成为未来政策的主要着力点。在未来很长一段时间内，膜法和蒸馏法仍将是海水淡化的两种主流工艺。扩大单机规模、降低海水淡化成本是海水淡化的重要发展方向，这有赖于相关设备国产化的推进。据统计，在我国16个万吨以上海水淡化项目中，只有25%（4）已建成。“十一五”期间，虽然取得了一些关键设备国产化成果，但在我国自己的建设项目中，相当一部分核心设备来自国外。海水膜组件、能量回收装置、海水高压泵等反渗透关键设备仍需从国外进口；海水蒸发器、冷凝器、蒸汽喷射器等热力海水淡化的核心材料和关键设备，与世界先进水平相比也有很大差距。这些因素严重制约了我国海水淡化技术的产业化。这一政策强调加强国内海水淡化技术和设备的研发，这意味着相关技术和设备厂商将首先迎来海水淡化产业化的发展机遇期。在海水淡化行业，投资机会主要来自市场份额大、技术和发展前景好的反渗透法，其次是低温多效法。水滑溜泵市场部负责人告诉记者，目前我国海水淡化装机容量中，反渗透法占60%。WATERSUNNY海水淡化泵是反渗透海水淡化系统的关键设备

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. 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.
