Guangzhou South Peak Industries Ltd. was established in 1995, the main products: portable fan Jiuzhou Jiuzhou pressure blower, CY / CF Jiuzhou centrifugal fans, axial fans Jiuzhou, stainless steel fan, wind wheel, shops while agents Jiuzhou fan, 9 Yang Soymilk, noodles machine, meat grinder, open buckets and other hotel kitchen appliances, Welcome! Second, the fan basic theory 1. Basic principles of gas and low noise centrifugal fan impeller role in a circular motion while the joint action by the centrifugal force and shear force centrifugal fan, forming a relative motion of the fluid. Due to the relative movement velocity and pressure variations, thus completing the impeller to the fluid energy transfer process. The prime mover of the gas energy into mechanical energy, wherein not only the fluid pressure increase, its kinetic energy is also increased accordingly. Due to changes in the flow field and pressure field Jiuzhou proof centrifugal fans, and ultimately boost the process fluid at the impeller. Guangzhou Nan Feng Industrial Co., Ltd. is committed to providing customers with superior quality products at reasonable prices, and continue to develop innovative, to better meet the different needs of customers. The company's operating principle is "integrity, customer first, quality." The main products are: portable fans, pressure blower, CY / CF centrifugal fans, axial fans, stainless steel fan, the wind round, while Deputy Jiuzhou fan shops, 9 Yang Soymilk, noodles machine, meat grinder, open buckets and other hotel kitchen appliances, Welcome! The characteristics of a centrifugal fan, ventilation effect, 4-72 centrifugal fan ventilation effect Jiuzhou low noise centrifugal fan, ideal for use in exhaust pipes or air; 2, applicability, 4-72 centrifugal ventilation machine is used in pipes conveying air blower, non-corrosive, flammable and explosive gas sites can be used. 3, low noise, 4-72 centrifugal fan air flow mechanics based on the reasonable angle impeller design, run, without any mechanical friction, blade-shaped lines make reasonable noise reduced to a minimum; 4-72 centrifugal fan noise generated high-frequency noise, as long as there is an obstacle, you can soundproof. 4, smooth, optimized impeller design allows axial force is reduced to a minimum, and there is an efficient impeller, and by the static and dynamic balance, so that the machine running smoothly, in the absence of any damping device case, bearing a relatively small amplitude. 5, low maintenance, because of its backward curved impeller, easy adhesion of dust and other media, the use of imported motor bearings. 6, easy maintenance, some models can be configured to clean up the door, disassemble Needless to maintain clean, saving time and effort. 7, durable casing and impeller made of high quality steel, making the fan more robust, the whole surface for spraying, anti-oxidation, not easy to be rust. Jiuzhou high pressure centrifugal fan _ _ Shenzhen Nan Fung Industrial centrifugal fan is provided by Guangzhou Haizhu South Peak Industries Limited. South Peak District Guangzhou Industrial Co., Ltd. (gzngf.1688.com) quality services and products, and are subject to approval and confidence in the new and old customers and the industry.
