1.行業發展現狀

當前，國內鼓風機龍頭企業都在加大研發投入，壯大科研團隊，不斷開發新產品，國內鼓風機企業與國外品牌在技術上的差距將進一步縮小。未來國內鼓風機企業將進一步占據國內鼓風機市場份額，同時，立足國內市場，走出國門，開發國際市場。據中國通用機械協會風機分會統計會員企業的數據，2020年國內鼓風機產量達到9萬多臺，產值為50多億元。未來，隨著污水處理、大氣污染治理等行業的發展，將進一步推動鼓風機需求增長，中國鼓風機行業仍有較大的發展空間。

2.新技術發展趨勢

提高效率、降低能耗是未來風機必然的發展方向。一是優化設計葉輪降低能耗，通過改變葉輪截面形狀進一步改進風機的風量、能耗、噪聲；二是提高轉速有效促進風機小型化，在提高效率的同時，達到縮小體積和減輕重量的效果；三是通過設計機殼風口形狀、運用回流消聲、共振消聲等先進技術實現風機的消聲降噪；四是實現智能化控制，利用PLC、DSP和觸摸屏對鼓風機的各種運行參數進行有效的控制，根據工況參數的變化自動實時調整風機的運行參數，以滿足流程的要求，并且通過對壓力、溫度、振動等參數的監控，保證風機的安全運行。

隨著國內制造高端化、智能化、綠色化的發展趨勢，部分風機企業開始瞄準制約各行業發展的節能降耗痛點問題。未來單級高速鼓風機將向高、中、低各種壓比的全系列產品目標發展，滿足不同行業領域的需求。以高效、可靠、無油、寬覆蓋為目標，以系列化、模塊化、標準化為抓手，提高產品綜合性能。未來行業將會大力推動節能型鼓風機的研制和應用，節能效果顯著的磁懸浮/空氣懸浮離心式鼓風機將有越來越大的發展空間。

3.市場前景

未來，隨著國家節能環保政策的有效實施以及行業技術水平的不斷進步，對鼓風機設備的能效要求會日益提高，具備節能高效、低噪音等優勢的磁懸浮/空懸浮離心式鼓風機市場前景廣闊。

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.
