HC Plastics News: On December 24th, it was learned from the 2017 Central Air Conditioning Association Annual Celebration Conference that the China Textile Engineering Society, Xi'an Engineering University and Shandong Jinxin Textile Fan Air Conditioning Equipment Co., Ltd. have been developing and practicing for three years. The successfully developed JF35/35-11 series paddle-type high-volume energy-saving textile axial flow fan is the only carbon fiber textile energy-saving fan in China. It is mainly used to replace those wind pressure surplus, insufficient air volume, long-term low-speed operation, noise. Need to reduce, improve efficiency and other aspects, it fills the domestic gap. It has been selected into the recommended catalogue of energy saving and emission reduction technologies for the Chinese cotton textile industry (the fifth batch).

The fan is an energy-saving fan specially designed for modern textile air conditioners. In addition to being suitable for the energy-saving mode of new plant air-conditioning, it can also be selected in design. At the same time, it also developed a material recovery system to achieve the perfection of complete sets of equipment from textile air conditioning to textile dust removal. The advantage is that it adopts moisture-proof design and has strong corrosion resistance. The blades of the impeller are made of high-strength aluminum (aviation aluminum) alloy. The impeller structure is divided into 3-6 blades (medium and low pressure), and there are also 8-10 blades. (medium and high pressure), the petiole is a triangular orifice plate, the wheel is a double round clamp welded hub core, which is manufactured by special process, reliable and durable, the fan cylinder is made of stainless steel or high quality carbon steel, and the fan is equipped with YE3 high efficiency energy-saving broadband motor. The scope of adaptation is extended to the occasions of medium and low pressure, high air volume, low noise and anti-riot air transportation.

The "China Textile" industry of the world factory, the level of China is the world level, and energy-saving transformation can only go its own way. The so-called "high-volume energy-saving fan", the current industry leader, is nothing more than two, one is similar to the rectangular airfoil blade axial flow fan, the other is the "sickle-shaped" blade-like "JF35/35-11 paddle airfoil" Fan.

In particular, the application of the JF35/35-11 new paddle-type high-volume energy-saving textile axial flow fan not only makes the modified system run, the airflow is smooth, and the speed operation in each frequency band can achieve "high efficiency". At the same time, it also meets the first-level energy efficiency standard stipulated by the national GB19761-2009 ventilator energy efficiency limit value and energy efficiency rating. The noise ratio is better than the 35 decibels specified in GB/T8690 "Industrial Fan Noise Limit". The power consumption per 10,000 air volume is only 1.6-1.8 degrees, which is 15-20% year-on-year.

It is understood that at present, many domestic textile manufacturers, air-conditioning fans and some return air fans, most of them run between 30-45 Hz, rather than efficient 45-50 Hz. The actual situation is that the air volume and wind pressure of the actual operating point of the fan are not matched with the pipeline system, the economic operation probability is small, and the low speed and low efficiency are mostly. The “energy saving” often sacrifices the important value such as comfort, temperature and humidity. In the airflow disorder, eddy current, back and forth oscillation, motor heating and invalid work loss.

In this design, the performance of the fan, starting from the performance distribution, greatly adjust the parameter (flow and pressure) distribution interval to ensure that the wind turbine needs more than 90% of the year to run the high-efficiency interval, that is, low speed Or high-speed operation, the fan is always running efficiently, in order to achieve the dual purpose of ensuring the process to reduce energy consumption, so as to maximize the energy efficiency of the enterprise.

Wu Zicai, general manager of Shandong Jinxin Textile Fan Air Conditioning Equipment Co., Ltd., said that the fan has the characteristics of “high efficiency”, “high air volume” and “low noise”. It is an environmentally-friendly and energy-saving new product specially designed for the textile industry. It is used for air conditioning air supply and workshop return air. It can promote air to overcome the flow resistance with minimum energy consumption, and realize “squeeze and wet” conversion and clean production.

Wu Zicai revealed that they have just signed a strategic cooperation agreement with China Textile Machinery (Group) Co., Ltd., which is not only for the two sides to respond to the party-side and the State Council's supply-side reform call, actively promote the restructuring and transformation of the domestic and international textile industry, or promote The textile industry is an important measure to improve the level of intelligent manufacturing, in order to promote the joint efforts of central enterprises and local superior enterprises to enlarge and strengthen the real economy. In the future, the two sides will fully utilize their respective advantages in marketing, design and development, and information sharing to support each other's business innovation and strategic development.
