Enterprise Purpose: Technology Promotes Enterprises for the Benefit of Humanity Enterprise Spirit: Seeking Truth and Innovation Integrity Enterprise Goal: Owning Sanhe Fan Wind Power by Your Enterprise Idea: Creating First Class Products with First Class Technology Enterprise Motto: Embracing All Rivers, Having Capacity is Big One, Sanhe Fan Technology Design 1. Sanhe Fan actively develops and produces nearly 50 series and more than 5000 specifications of various "specialized, special, and new" application fans in various fields. 2. Sanhe Fan actively participates in international ventilation equipment industry product exhibitions, exchanges and absorbs advanced technology achievements from fan manufacturers such as the United States, Germany, Japan, etc., and optimizes and combines technology. 3. Sanhe Fan is market-oriented and regularly sends its fan technical design personnel to visit customers to obtain information on the actual usage status and areas for improvement of fan equipment. Combining advanced technologies at home and abroad, it continuously innovates and creates more perfect fan products to meet customers' more target needs. 2、 Sanhe Fan Technology Manufacturing: Sanhe Fan has complete production facilities, advanced process flow, and complete testing equipment. Strictly monitor the entire production process in accordance with ISO90001 quality system requirements. 1. Fan manufacturing process FRP fan: All components such as impeller, air duct, hood, etc. are made of imported brand resin, and the surface is made of anti ultraviolet and anti-aging gel coat, and high-quality FRP fiber cloth is manufactured in scientific proportion. The complete set of fiberglass centrifugal fans is imported with advanced production technology from abroad, and fiberglass cutting is processed using CNC high-pressure water jet cutting. It has the characteristics of light weight, high strength, flame retardancy, and corrosion resistance. Fan outer cylinder: steel plate cutting (shearing machine or plasma cutting machine), drum forming (three core drum machine), automatic welding (CNC arc welding machine, CNC straight seam welding machine), spinning forming (automatic spinning machine), flange and cylinder integral forming. Compared with traditional processes (welding angle steel rings and cylinders), it has obvious advantages such as beautiful appearance, strong structure, and good flow guiding performance. Fan impeller: All components such as blades and hubs are formed using compression molding technology, welded by CNC welding machines, and assembled on assembly lines, with precise dimensions and beautiful appearance. A hard supported dynamic balancing machine is used for calibration, and the entire calibration process is computer-controlled. The impeller balance accuracy is high (able to reach ISO2.5 level), and the operation is smooth. 2. Quality inspection of fan manufacturing materials before entering the factory: There are a series of complete "material storage inspection standards", and all materials undergo strict inspection before being stored. Key component inspection: 1. Hot rolled steel plates produced by Shanghai Baoshan Iron and Steel Group must be used as designated steel plates, and the seller must provide Baoshan Iron and Steel Group's quality inspection report; Before the motor is stored, it must undergo noise, vibration, and current testing to meet international and corporate requirements; Before assembling the impeller, the first step is to undergo static balance testing and adjustment to ensure that the static balance of the impeller meets international and corporate requirements. Then, the impeller is balanced and adjusted on a dynamic balancing machine to ensure that the dynamic balance of the impeller meets international and corporate requirements. Impellers that cannot be adjusted must be scrapped. Inspection of finished products before storage: Each fan must undergo the following tests before being released for storage:; Appearance inspection: The appearance is neat and the paint is intact and undamaged; Operation detection: Under normal load, the operation time is greater than 30 minutes without any abnormalities; Vibration detection: During operation, use a vibration meter to detect the overall vibration speed of the machine, which must not exceed international and enterprise standards; Noise detection: Conduct noise testing on fans according to international standards, and ensure that the noise level is below international and corporate requirements; Overspeed test: Conduct an overspeed test on the willow using an overspeed testing machine, and run for more than 10 minutes at a speed exceeding 20% of the rated speed; Whole machine operating current detection: Under normal load, the current passing through the motor during operation is detected. If the current exceeds the standard requirements, the motor configuration needs to be changed. Pneumatic performance type test of fan: equipped with a complete set of testing equipment required by the national industrial product production license, certified by the national testing unit. According to GB1236 "Test Method for Aerodynamic Performance of Ventilators", the comprehensive performance sampling test of the factory fans is carried out on the company's duct type test device in batches with the help of advanced testing and inspection instruments. All new products designed and developed by the company, as well as derivative products of standard products, must undergo testing in the pneumatic performance laboratory and obtain a test report. Only those whose performance indicators meet the design requirements can be put into formal production.
