The Application of FD500 Frequency Converter in the aquatic feed industry
In recent years, driven by the "dual carbon" strategy and the "industry transformation" development, the feed industry has entered a stage of integration and upgrading. The industry has gradually shifted from being quantity-oriented to a quality-oriented high-quality development stage. Since 2022, China has continuously eliminated backward production capacity, accelerating the industry's large-scale transformation and further enhancing the concentration of enterprises.
The feed industry, as one of the key foundational industries that affect China's national economy, originated in the 1970s. In 2011, it surpassed the United States to become the world's largest, accounting for approximately 17% of the global feed production. In 2022, the total output value of the national feed industry reached 1,316.85 billion yuan, increasing by 7.6% year-on-year; the total industrial feed output was 3,022.34 million tons, an increase of 3.0% compared to 2021, and the industry scale remained the largest in the world.
With the increasing demand for the variety and quantity of aquatic products, aquaculture has developed rapidly, and the demand for feed has also risen accordingly. As a result, aquatic feed extruders have emerged. As a major input in aquaculture production, the quality of aquatic feed determines the quality of the aquaculture industry. The feed produced by aquatic product extruders can utilize more inexpensive raw materials, reduce the usage of binders and fungicides, and have a higher feed production utilization rate. Its inherent characteristics are also more suitable for modern and large-scale aquaculture.
1. Requirements for frequency converters in the aquatic feed industry
As the number of electric motors used in feed processing equipment in enterprises increases, using frequency converters to carry out technological transformation of motor power supplies has become an important means for enterprises to save energy, reduce consumption and improve efficiency. However, the uneven quality of frequency converters in the market has instead caused great trouble for production. Therefore, the aquatic feed industry has put forward the following requirements for frequency converters:
High stability
The frequency converter needs to have high stability to prevent the production line from being unable to operate normally due to the failure of the frequency converter.
Low-frequency torque is high.
The variable frequency converter needs to have a high torque at the moment of starting the extrusion, in order to avoid unnecessary alarms caused by this and prevent any disruption to the normal operation of the equipment.
The impact force of the power grid is small.
It is necessary that after the frequency converter is turned on, it can effectively suppress the harmonic current interference to the power grid and reduce the impact damage to the power grid.
Easy to operate
The frequency converter should be easy to operate and learn, avoiding the time cost of long-term training and the cost of professional operation personnel.
2.FD500 Low-voltage frequency converter
Adopting a future-oriented modular design concept, the combination and replacement of each module of the frequency converter are flexible and simple, making the application and maintenance of the product stable and reliable.
The power unit can operate independently
The power unit itself can operate independently through additional terminals for start-stop, forward-reverse rotation and communication control. This can further simplify the control and reduce costs in many scenarios.
Supports vector control for multiple types of motors
Supports VVC+ vector control for induction motors, permanent magnet synchronous motors and synchronous reluctance motors.
Enhanced-coated circuit board
The standard 3C3 environmental grade circuit board coating ensures higher reliability in harsh environments and extends the service life of the frequency converter.
Built-in RFI filter
The entire series is equipped with C3-level RFI filters, which can reduce electromagnetic interference and enable the frequency converter to achieve EMC performance suitable for Class II environment (industrial environment) and be used without restrictions.
Instant stop and non-stop function
When the power grid experiences an instantaneous power outage, the frequency converter will be controlled to decelerate, thereby reducing the production disruption caused by the instantaneous power outage of the power grid.
Wide voltage range design
It can operate within a voltage range of 200 to 240V/380 to 480V, with a tolerance of ±10% of the specified values, and can meet the demanding power grid conditions of users.
By developing more intelligent and efficient technical equipment, we help the aquatic feed industry meet the growing market demands, actively explore innovative technologies and products, and provide more professional solutions for the aquatic feed industry. In the future, we will fully support the aquatic feed industry in achieving a more efficient and intelligent production model under the "dual carbon" goals, and inject more impetus into the intelligent transformation.
