Axial fan features control system to be broken through

Release Time：2021-07-20

As the name implies, an axial flow fan is an airflow in the same direction as the axis of the fan blades. For example, an electric fan and an air conditioner external fan are fans operating in an axial flow mode. The reason why they are called "axial flow" is that the gas flows parallel to the fan axis. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial flow fans are fixed in position and move air. Characteristics of axial flow fans:
1. Small axial flow fan: low power consumption, fast heat dissipation, low noise, energy saving and environmental protection, etc., due to its small size, it is widely used.
2. The large axial flow fan has the characteristics of simple structure, stable and reliable, low noise, large air volume of axial flow fan and wide range of function selection.
Axial flow fan in the cold storage on the operation of the cold storage is affected, because it will generate heat, it generates heat to increase the consumption of cold storage, so from the point of view of energy saving, we should try to reduce the axial flow fan boot time and boot number.
However, in the actual storage of fruits and vegetables, it is not only economical but also ensures the product quality, so a better treatment method is needed: to ensure rapid cooling when the fruits and vegetables are just put into storage, all axial flow fans are turned on, the number of units turned on is reduced after the storage temperature is stable, and for storage varieties with strict temperature requirements, in order to make the upper and lower temperatures uniform, 1-2 axial flow fans are still kept running when the axial flow fans are stopped to stop.
The fan control system is an important part of the fan, which undertakes the important tasks of fan monitoring, automatic adjustment, achieving maximum wind energy capture and ensuring good grid compatibility. It is mainly composed of monitoring system, main control system, pitch control system and frequency conversion system (inverter).
In terms of the requirements of the fan control system itself, it does have its particularity and complexity. The task of the fan control system is not only to realize the highly automatic monitoring of the fan and supply power to the power grid, but also to maximize the current wind energy capture and minimize the load of the axial flow fan through appropriate control. Even if the general automation enterprise can develop a prototype, it is difficult to verify and promote it, however, small and medium-sized wind turbine manufacturers are unable to carry out such development. So far, they still rely heavily on foreign brands, which is still the weakest link in the wind power equipment manufacturing industry.
Through the efforts of the past few years, domestic enterprises have made positive progress in the development of the main components of the control system, and have basically formed their own technology development capabilities. What they lack is mainly the large-scale commissioning performance of products and the accumulation of technology and experience.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license. It is the first in the industry to pass ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health management system certification, and an axial fan invention patent, A fan utility model patent, environmental assessment, safety assessment, three simultaneous and other procedures are complete.
