The working principle of the fan is basically the same as that of the turbo compressor, but because the gas flow rate is low and the pressure does not change much, it is generally not necessary to consider the change of the specific volume of the gas, that is, the gas is treated as an incompressible fluid. The relationship between fans and fans: Fans are the abbreviations for gas compression and gas transportation machinery in China. Generally speaking, fans include fans, blowers, compressors, and roots blowers, but do not include volumetric blowers such as piston compressors and compressor. Ventilator is a product type of fan, but people usually call the ventilator simply as a fan, which is another name for a fan.
As China enters the stage of new-type industrialization, the basic industry is developing in the direction of large-scale equipment, environmental protection and energy saving. In response to this, the ventilator industry has gradually entered the upgrading and upgrading stage under the background of continuous improvement of its own technological level, and products are also being manufactured. Integration, energy efficiency, computerization of design and production, and globalization of sales are developing. At the same time, user demand for fans is shifting from product-oriented to life-cycle service-oriented. A ventilation system, in addition to the fan body, also needs mufflers, combined air valves and control cabinets. Compared with the past customers' decentralized procurement and assembly, ignoring product performance matching and applicability of specific working conditions, the integrated ventilation system performs better in optimizing fan efficiency, increasing overall stability, and saving area.
With the increasing awareness of energy conservation and consumption reduction in the whole society, the ventilator has further developed in the direction of high efficiency and energy conservation. For example, in the design and manufacturing technology of the fan, the controllable vortex ternary impeller design technology is used to suppress the strong vortex flow and The separation loss is reduced. At the same time, the finite element analysis software is used to quantify the structural strength of the product, the stress of the blades and the hub, and the natural vibration mode to ensure the structural strength and service life of the product, and improve the operating efficiency and safety performance of the fan. In addition, through the system energy-saving transformation of the active wind turbine, the actual operating parameters of the wind turbine can be improved, and the operating efficiency of the wind turbine system can be improved to achieve the purpose of energy saving.
The business model of the fan industry is related to its product characteristics. Low-end products in the industry are basically standard parts, and companies usually maintain a certain inventory of finished products. High-end products are basically non-standard parts. Enterprises generally adopt the order production and direct sales service model, that is, after the enterprise obtains the product supply order through bidding, it arranges the product production according to the order. Industry high-end product suppliers improve their profitability and competitiveness by focusing on product quality, technology development, brand management, and after-sales service. In recent years, large and medium-sized enterprises in the industry have focused on introducing advanced foreign technologies, using foreign advanced technologies to improve and optimize existing products, stabilize production processes, and reduce product energy consumption and noise. At the same time, through the introduction of technology to improve product development capabilities, continue to fill domestic gaps, meet customer needs and improve the efficiency of business operations.
