Product Profile Large energy saving ceiling fans are green energy saving products of the 21st century. It has many advantages, such as powerful, no noise, zero pollution, low energy consumption. It is very popular for large masses of users. It is not only mainly used in steel structure plant, logistics warehouse, farm and other large enterprise buildings, but also agricultural markets, gymnasiums, waiting rooms, exhibition halls and other large public buildings. A large energy-saving ceiling fans with a speed of 50 revolutions per minute 1 to 3 meters per second to make the human body feels the best wind speed. A breeze from all directions gently caresses the body and increases the evaporation of human sweat. The cooling effect of 5 to 8 degrees is similar to the comfort presented by the natural breeze, which can not be matched by other fans. It is an ideal choice for indoor, ventilation and cooling in summer to remove humidity and heat. Only seven degrees of electricity per day, it can be cool for a whole summer. Energy saving comparation In summer, the sun shines directly and the indoor temperature is more than 40 degrees on average. Common industrial exhaust fans can only increase the indoor temperature. Industrial air conditioners consume thousands of kilowatts of energy every shift. There is no obvious unenclosed cooling in the space, which also increases the operating cost of enterprises. The emergence of a large energy saving ceiling fan brought the perfect solution. An energy saving fan with a diameter of 7.2meters can push the air to produce a large amount of winds effectively. The continuously rotating blades of circular form an airflow field with an effective area of 600 to 800 square meters. No other device has not yet been compared. The large energy-saving ceiling fan praduced by Linter technology has the characteristics of high reliability, feasibility and low power consumption. The controller unit used the stability of the energy-saving inverter system. In practice, the average power consumption is less than one killowatt per hour. It can guarantee more than 5,000 hours of uninterrupted operation. Linter7200 of a large energy-saving ceiling fan can cover the area of about 50 small fans of 0.75 megabytes worked. In a factory of 9000 square meters, if full coverage is to be achieved, it needs about 300 small fans or industrial 6 energy-saving fans. According to the use of four years, every eight months, every day for ten hours, can be run for 10,000 hours, about 90000kw power consumption, than the small wind 1080000kw, save 990000kw, save energy by 92%. When meeting the extreme high temperature climate, the large energy saving fans and air conditioners are used together, it will be coller. Using A large energy-saving ceiling fan for air supply can not only save the air conditioning tube, but also save more than 30% energy. Attentio Lectotype The building structure: H-shaped steel, I-shaped steel, Mixed steel square bar spherical column spherical structure. The total height of the building is more than 4, 0m, less than 15m. 1, 0m. The minimum distance between the fan and the roof is 1, 0m. The minimum safety distance between the fan blades and the obstacle is 0, 3 m. The distance between the fan blades and the wall on both sides is more than 1, 5 m. Effects of various environments on fan performance. Open space, promotes air circulation. Indoor airflow circulation in enclosed spaces is suitable for use with air conditioning. In a multi-fan environment, due to the low wind speed, caused by the fan, there will be no cyclones. The distance between the two fans will be separated before the wind will not cancel, and the coverage area will be increased at the same time.

Recently, the new generation of digital servo multi-axis drive CJ40S cotton comber independently developed by Shanghai Textile Machinery General Factory has been successfully operated in the field at the test base, which has attracted great attention from domestic and foreign counterparts and experts. It has become the electrical automation product of Pacific Electromechanical Group. New highlights. The new high-speed combing machine with unique electronic cam, multi-axis synchronous operation and bus control technology has a leading position in digitalization.
At present, the combing machine sold in the domestic and international markets is generally driven by the main motor to perform mechanical movement, and the movement of each component is performed. The detaching roller motion is composed of a cam four-link + differential gear train or a multi-link + differential gear train, and the structure is complicated. The separation motion curve and the effective output length cannot be adjusted according to the change of the yarn branch; the motion fit between the nipper plate and the detaching roller is not ideal due to the difference in the cotton fiber and the ratio of the ratio. Under the leadership of Pacific Electromechanical Group, Shanghai Textile Machinery General Factory has experienced the research and development of cotton combing machines for nearly half a century through repeated market research, and with the cooperation of relevant universities and cotton spinning enterprises, bold innovation, application of computers, digitization, The network technology has successfully developed a new generation of servo multi-axis drive cotton comber with high automation, intelligence and digitization. The device uses the servo controller and servo motor of the electronic cam function to replace the original mechanical cam and planetary wheel system. The servo motor directly drives the high-speed operation of the comber separation roller. The virtual electronic cam has high precision and no wear, and can be drawn every cycle. Thousands of points, multiple curves are pre-stored in the controller, and can be easily switched at any time. At the same time, the development process software selects the applicable process method for different types and ratios of cotton yarns, through PCC controller, man-machine interface, The mainframe frequency converter, one servo controller, two closed-loop controlled inverters and encoders form a comber with four-axis synchronous operation, with accurate accuracy, accurate tracking and stable start and stop. The new model takes the lead in using industrial bus control technology to enable a high data exchange speed between the control device and the drive device, realizing an ordinary operator's change of the separation curve and the adjustment of the speed ratio between the master and the slave axes. The man-machine interface can be completed in a few seconds. In addition, the new model also provides an Ethernet interface for upward communication, which facilitates centralized control and management of the entire production line.
The servo multi-axis drive cotton comber is the scientific crystallization generated by the latest design concept of Shanghai Textile Machinery General Factory. Its structure is simple and energy-consuming, the cotton web produced is even, and there is no broken edge to break the net, which not only saves raw cotton, but also improves products. Grade, CV% can be increased by about 20%; the combination of different lengths of cotton fiber can make cotton spinning enterprises respond quickly to market demand. At present, the utility model patent has been authorized, and the invention patent has been announced. The product has been submitted to the national “Eleventh Five-Year Plan†863 Program Major Project Proposal.
