The FGI FD590 solar pump inverter makes salt production greener and more efficient
Salt is an indispensable condiment in our daily life. Three meals a day cannot be without salt. The Book of Han states that salt is the general of the eater. If people do not eat salt for a long time, they will suffer from various diseases. There are many kinds of salt sold in supermarkets, such as sea salt, well salt, and mine salt, etc. Salt according to the source categories: divided into two categories: sea salt and salt lu, lu has mineral salt, salt lake salt, well salt. Recently, due to the discharge of nuclear wastewater from Japan, a large number of consumers have boycotted sea salt. At the same time, the demand for land salt has risen rapidly. Among them, well salt is also the most common type. Salt made by extracting water from Wells at a depth of 1,000 meters underground through well drilling is called well salt. Salt industry is one of the traditional industry, with the constant progress of science and technology, the continuous improvement of market demand, ZhiYanChang also began to gradually introduce automation technology to improve production efficiency and reduce cost.
2.User demands
In order to better meet market demands and enhance the competitiveness of the enterprise, a certain salt factory has decided to introduce solar pump inverter technology to automate and upgrade its production process.
At the same time, upgrade requirements have also been proposed:
(1). Improve production efficiency: By using solar pump inverter technology, increase the operating speed and stability of the equipment, thereby enhancing production efficiency.
(2). Reduce energy consumption: Through solar pump inverter technology, achieve energy-saving operation of the motor, reducing energy consumption.
(3). Improve product quality: By using solar pump inverter technology, achieve precise control of process parameters, improving product quality and consistency.
(4). Lower equipment maintenance costs: Through solar pump inverter technology, realize soft start and soft stop of the equipment, protecting the motor and mechanical components of the equipment, and reducing maintenance costs.
3.Solution
This time, the FGI FD590 solar pump inverter is applied in the production process of well salt:
The production process of well salt:
In the early stage, through exploration, a suitable salt well is found, and then the brine 1,000 meters below is extracted. It is filtered and undergoes three stages of sedimentation in the sedimentation tanks to remove more impurities. After passing through the three sedimentation tanks, the salt sludge is filtered out by the filter press and transported to the salt factory. Then, it undergoes melting, dehydration, refining, filling, and packaging to form the edible salt we consume.
The FGI FD590 solar pump inverter is used in this application to feed the settled slurry into the filter press to make the salt form crystals rapidly, and then dry it to prepare for the next stage of refining.
Control Requirements
(1). The external terminals of the frequency converter must support both remote and local control for starting and stopping, as well as display of the frequency converter's operation and fault status.
(2). The frequency converter should allow for continuous speed adjustment through analog input.
(3). The frequency converter should enable remote monitoring of its operating frequency.
(4). The frequency converter must have overload capacity.
4.Specific effect presentation
In this case application, the FGI FD590 solar pump inverter demonstrated the benchmark technical strength in the industry, and was highly favored and affirmed by the manufacturers.
Firstly, the FGI FD590 solar pump inverter features a large torque at low frequencies and high torque at low speeds, with a 150% overload capacity. This enables it to provide sufficient power to ensure the stable operation of the equipment.
Secondly, this frequency converter can achieve continuous speed regulation. This means that it can adjust the frequency at any time according to the actual working conditions, enabling energy-saving operation and meeting the maximum pressure requirement of the filter press.
Thirdly, the motor adopts a soft start and soft stop method. This approach can effectively protect the mechanical performance of the motor and thereby extend the service life of the equipment.
Finally, the frequency converter also has comprehensive functions such as overcurrent, overload, phase loss and overvoltage protection. These functions can effectively protect the motor and extend its service life.
