Magnetic particle inspection method fan rotor or impeller around the wire, Walter DC impeller or rotor generates a magnetic field. Each impeller and become a pole at the top, and then coated with iron powder. If there is a crack in Shanxi blade wind turbine suppliers, generate two different polarities in the gap at the crack, which will suck iron. This can find out where the injured leaves scars. Phosphor coated phosphor testing blade, then wiped off. The rotor or impeller to move to the darkroom View Shanxi fans to order, there is a crack at the phosphors glow and indelible. These are the fan impeller fan manufacturers to introduce Shanxi damage inspection method, if you want to learn more Information Shanxi fans, stay tuned to our official website, you can also call Shanxi fans, we will be happy to serve you and look forward to your visit! air volume adjustment is the amount of wind by what means to achieve the fan regulation is an important benchmark fan effect control, and related factors involved fan capacity, including related power fan impeller design, the motor is set there The wind turbine is provided with a regulating valve chamber. First: the fan impeller design. Traditional fan impeller designs are almost iron, and no breakthrough on the aerodynamic exterior design at the technical level, but today's fan impeller has long appeared to try other materials, such as: plastic and aluminum. From the appearance, due to the constant demand to emerge Shanxi fan parameters, how to create the most efficient and least cost to the customer and the product has become a common choice for businesses, and therefore expansion appear on the exterior design of the impeller, and other multi-leaf Try species. Second: the motor-related power. The motor is driven by the rotation of the core parts of the impeller, a technological breakthrough on the motor could bring the entire wind turbine including the impeller, the overall trend of lightweight, lightweight design and facilitation of change. Therefore, investment and technological breakthroughs in technology R & D expenditures on the motor fan became the core issue of business, but also how their fan product advantage out of the international market conditions. Third: adjusting the valve chamber wind turbine design. Fans from the application range can be divided roughly into gas-class fans, industrial fans and other categories. And because of the characteristics of the industrial class fan application goals: such as forced air cooling, kitchen fire regulation decided to add regulating valve design in the design, in order to more easily and quickly adjust the wind carried.
