提高效率、降低能耗是未来风机必然的发展方向。一是优化设计叶轮降低能耗，通过改变叶轮截面形状进一步改进风机的风量、能耗、噪声；二是提高转速有效促进风机小型化，在提高效率的同时，达到缩小体积和减轻重量的效果；三是通过设计机壳风口形状、运用回流消声、共振消声等先进技术实现风机的消声降噪；四是实现智能化控制，利用PLC、DSP和触摸屏对鼓风机的各种运行参数进行有效的控制，根据工况参数的变化自动实时调整风机的运行参数，以满足流程的要求，并且通过对压力、温度、振动等参数的监控，保证风机的安全运行。

随着国内制造高端化、智能化、绿色化的发展趋势，部分风机企业开始瞄准制约各行业发展的节能降耗痛点问题。未来单级高速鼓风机将向高、中、低各种压比的全系列产品目标发展，满足不同行业领域的需求。以高效、可靠、无油、宽覆盖为目标，以系列化、模块化、标准化为抓手，提高产品综合性能。未来行业将会大力推动节能型鼓风机的研制和应用，节能效果显著的磁悬浮/空气悬浮离心式鼓风机将有越来越大的发展空间。

3.市场前景

未来，随着国家节能环保政策的有效实施以及行业技术水平的不断进步，对鼓风机设备的能效要求会日益提高，具备节能高效、低噪音等优势的磁悬浮/空悬浮离心式鼓风机市场前景广阔。

1. Industry development status

At present, leading domestic blower enterprises are increasing investment in research and development, expanding research teams, and constantly developing new products. The gap between domestic blower enterprises and foreign brands in technology will be further narrowed. In the future, domestic blower enterprises will further occupy the market share of domestic blowers. At the same time, they will base themselves on the domestic market, go abroad and develop the international market. According to the statistics of member enterprises from Fan Branch of China General Machinery Association, the domestic blower output will reach more than 90000 in 2020, with an output value of more than 5 billion yuan. In the future, with the development of sewage treatment, air pollution treatment and other industries, the demand for blowers will further increase, and there is still a large space for the development of the blower industry in China.

2. New technology development trend

Improving efficiency and reducing energy consumption are the inevitable development direction of wind turbine in the future. First, optimize the design of the impeller to reduce energy consumption, and further improve the air volume, energy consumption and noise of the fan by changing the shape of the impeller section; The second is to effectively promote the miniaturization of the fan by increasing the speed, which can reduce the volume and weight while improving the efficiency; The third is to realize the noise reduction of the fan by designing the shape of the casing tuyere and using advanced technologies such as reflux noise reduction and resonance noise reduction; The fourth is to achieve intelligent control. PLC, DSP and touch screen are used to effectively control various operating parameters of the blower, and the operating parameters of the fan are automatically adjusted in real time according to the changes of working conditions to meet the requirements of the process. Besides, the safe operation of the fan is guaranteed through the monitoring of pressure, temperature, vibration and other parameters.

With the development trend of high-end, intelligent and green manufacturing in China, some wind turbine enterprises have begun to focus on the energy saving and consumption reduction pain points that restrict the development of various industries. In the future, single-stage high-speed blowers will develop towards a full range of products with high, medium and low pressure ratios to meet the needs of different industries. Aiming at high efficiency, reliability, oil-free and wide coverage, and focusing on serialization, modularization and standardization, improve the comprehensive performance of products. In the future, the industry will vigorously promote the development and application of energy-saving blowers, and the magnetic suspension/air suspension centrifugal blowers with remarkable energy-saving effects will have more and more room for development.

3. Market prospect

In the future, with the effective implementation of the national energy conservation and environmental protection policy and the continuous progress of the industry's technical level, the energy efficiency requirements for the blower equipment will be increasingly improved. The magnetic suspension/air suspension centrifugal blower with the advantages of energy conservation, efficiency, low noise, etc. has a broad market prospect.
