Because of its lightweight structure, convenient use, high production efficiency, and low energy consumption, power tools have been widely used in the industry to develop indispensable homework tools for families. At present, China is, of course, the world’s major exporter of power tools, but it still has great export potential and potential target markets.
Currently, industrial countries in economically developed regions, such as Germany, the United Kingdom, the Netherlands, and France in the European region, the United States and Canada in the North American region, and Japan and other countries in the Asian region, use electric tools in homework and are common, accounting for the total output. About 50% to 70% of China's electric power tool products have a large share in the domestic electric tool product market in the above-mentioned countries and regions, but the industrial electric power tools produced in China do not export a large amount to these regions. Professional power tools for industrial use have high technical content, strict safety and electromagnetic compatibility requirements, and have delineation of function, work efficiency, reliability, and durability. The price is several times that of similar DIY tools, and even 10 times or more. Professional power tools have internationally known brands such as hammers from Helde, Bosch, and Mai Taibao, drills from Black & Decker, electric tools from Makita and other woodworking tools, and circular saws from the Century.
China's export of dynamic tools has accounted for 80% of the world's sales of electric tools, but the export amount only accounts for about 20% of total sales. The main reason is that China's electric tool manufacturing industry has not yet established its own brand in the international market, especially the industry. With professional electric tools, the use of OEMs is generally adopted, and the market competition among enterprises in Shanghai is not standardized, making export prices lower and lower. For example, in 2001, the uniform price for electric tools was US$12.72 per unit, while the average export price of foreign-funded enterprises was US$18.74 per unit, and the average price of imported electric tools was US$45.94 per unit. Therefore, after China has improved its product technology level, developed industrial power tool products, and established its own famous brand, it will surely be able to expand the market and create greater economic benefits.
Electric tools are relatively rare in the economically underdeveloped or relatively backward third-world countries. With the development of the economy and the improvement of the material and cultural level, the use of power tools in the family’s life will gradually increase. For example, in the Asian region, the market share of electric tools sold by China to Asian countries has been increasing year by year, compared with 2003 and 2002, with an increase of 2.6 percentage points. Therefore, the latent market for household electric tools in developing countries and economically underdeveloped countries is very large.
With good products and quality assurance, it is particularly important to carry out proper brand promotion. You can establish your own sales channels in the country, promote marketing through agents, and cooperate with the media, etc. A lot of this requires companies to work hard to find the right way. Another is after-sale protection. The after-sales service of domestic enterprises is not in place, or basically there is no after-sales service, which has become a major weakness for us. In the face of increasingly fierce market competition, if domestic companies do not attach importance to this, it will affect their long-term development, and good service is also a top priority.
Turbine Centrifugal Fan
Features: Turbine centrifugal fan impeller adopts the international standard backward design, the perfect streamline structure, large openings into the center of the impeller inlet wind, the wind through the center port into the wind, resulting in a strong centrifugal force, by the backward tilt fan blades thrown off quickly Turbine structure design makes the wind turbine has a strong wind, wind pressure.
Highlights: Turbine centrifugal fan by the overload thermal motor protection of the outer rotor, high efficiency after the circular arc-shaped centrifugal impeller of two parts. All impeller mold production, high precision dynamic balancing machine calibration, with small size, high efficiency, air volume, small vibration, low noise, superior performance, easy installation and commissioning.
Application: Material: Made of PA6 plastic, plastic one molding process. Diameter size 155mm ~ 250mm.
Applications: Air purification equipment, factory equipment (printing equipment, chemical fiber equipment, etc.), medical equipment, fresh food cabinets, refrigeration cabinets, servo motors, inverters, pipe ventilation, dehumidifiers, etc.
Volute centrifugal fan:
Features: Volute centrifugal fan impeller driven by the motor rotation, the impeller blades forcing gas rotation, the gas to work, to increase its energy, the centrifugal force in the gas around the impeller thrown through the scroll casing will speed Can be converted into pressure energy, when the impeller gas is discharged, the impeller pressure is lower than the pressure inside the inlet, the new gas in the pressure difference under the action of inhalation impeller, the gas is continuously exported from the outlet.
Highlights: The fan is designed with a reasonable impeller angle according to the aerodynamics of air flow. Without any mechanical friction during operation, a reasonable blade shape line minimizes the noise. The optimized impeller minimizes the axial force and has an efficient impeller , And the static and dynamic balance correction, the machine running smoothly, without any damping device, the bearing amplitude is relatively small.
Application: Material: Aluminum die-casting frame, wind wheel made of galvanized sheet, surface black electrophoresis, size Diameter: 120mm ~ 160mm
Applications: Sterilizers, heat exchange systems, clean benches, air shower, laboratory equipment, etc.
choose the suitable fan
1, the first parameter to note are: air volume, total pressure, efficiency, sound pressure level, speed and motor power.
2, Centrifugal fan pressure can be divided into three categories: high pressure centrifugal fan P> 3000Pa, medium pressure centrifugal fan 1000≤P≤3000Pa and low pressure centrifugal fan P <1000Pa. Depending on the stupid physicality and chemical properties of the delivered gas and the use, etc., different types of centrifugal fans are selected.
3, taking into account the loss of air leakage pipeline system, calculation error, as well as the actual fan fan, wind pressure negative deviation, centrifugal fan selection, the general use of air flow rate of 1,05 ~ 1,1, wind pressure of 1,10 ~ 1,15 safety factor. In order to prevent long-term fan in low-efficiency operation, it is not appropriate to use excessive safety factor.
4, in order to make the fan stable operation, should make the fan work in the vicinity of its efficiency, the fan operating point is located in the performance curve of the full pressure peak point on the right (ie, gales side, and is generally located at full pressure peak 80%). Fan design efficiency of the selected conditions, not less than 90% of the fan efficiency.
5, the use of variable frequency fan, the total pressure loss should be calculated as the system rated pressure, but the fan motor power should be calculated on the additional 15% to 20%.
