Application of FGI FD100 Low Voltage Frequency Inverter on sand ships

1.Overview

Sand is one of the most basic materials in the construction industry and is in high demand. How to obtain large amounts of sand to meet the needs of modern buildings, in the numerous sand harvesting equipment, sand dredging ship is one of the most widely used equipment. Sand dredging vessels are more distributed in the Yangtze River Triangle and the Pearl River Triangle. Sand dredging vessels at the Jianghai mouth can produce a lot of construction sand. Secondly, it can dredge the river to avoid the formation of large sand beaches and facilitate the construction of large ships berthing port.

FGI frequency inverter has its high performance and high cost performance advantages in a large number of applications in sand dredging boats, so that the enterprise has obtained great economic benefits, has been unanimously recognized by customers. Next, we will introduce the energy saving transformation application of FD 100 frequency inverter in sand dredging boat.

2.Implementation plans

The sand dredging boat drive system uses a FGI FD100-220KW frequency inverter applied in the sand dredging device, and the drive motor drags the overweight load to achieve stepless speed regulation. The frequency inverter adopts external terminal three-line system control and external potentiometer speed regulation, which meets the remote start and stop speed control of both places. According to the environmental characteristics of diesel engine and the poor power quality, the long routing and easy interference, the input reactor and output reactor to increase power factor and suppress electromagnetic interference.

3. Application advantages

The use of FD100 low voltage frequency inverter can have no impact on the power grid, and the power loss is small at low speed, which plays a role in energy saving. When the diesel generator set is selected, the power can be appropriately reduced and the cost can be saved.

With the support of FGI FD100 high-performance frequency inverter, the system makes the motor low frequency output torque large, the drag overweight load runs smoothly without lag, and controls the motor to achieve infinite speed regulation, which meets different production requirements and greatly improves the production efficiency.

FGI FD100 low voltage frequency inverter has intelligent protection functions such as phase deficiency protection, undervoltage protection, overload protection, etc. When there are obstacles underwater, the frequency converter can play an effective role in protecting the motor and diesel generator, making the system stable and reliable.
