1. Introduction

With the continuous acceleration of urbanization, the efficiency and reliability of urban drainage systems have become of vital importance. Municipal strong drainage facilities, as an important component of urban infrastructure, undertake the crucial task of ensuring smooth urban drainage and preventing urban flooding and water pollution. Against this backdrop, the adoption of advanced frequency converter technology to upgrade and optimize municipal strong drainage facilities has become a trend, providing a new solution for the sustainable development of urban drainage systems.

2.Industry overview

Municipal strong drainage facilities are an important part of urban infrastructure, covering drainage pipes, drainage channels, rainwater grates, rainwater inlets and other facilities. The traditional drainage system often has problems such as high energy consumption, poor operational stability and high maintenance costs during operation, and needs to be upgraded and renovated to improve efficiency and reliability.

3.System working principle and control requirements

The FGI FD800 frequenc inverter, as an advanced control device, can regulate the rotational speed of the motor to control the output power of equipment such as water pumps and fans. By introducing the FGI FD800 frequency inverter into municipal strong drainage facilities, precise control of water pumps and fans and other equipment can be achieved. According to actual needs, the operating parameters can be dynamically adjusted, thereby improving the energy efficiency and operational stability of the system.

4.Control requirement

Pressure Control: The FD800 frequency inverter can control the pressure through controller signals, ensuring that the pipes and equipment in the drainage system can operate within a safe range.

Fast Response: The FD800 frequency inverter has the ability to respond quickly, able to adapt rapidly to changes in water demand in the system.

Energy Efficiency Control: While adjusting the speed of the water pump, the FD800 inverter also focuses on energy efficiency control, ensuring that the system can maintain efficient operation under different load conditions and reduce energy waste.

Fault Monitoring and Alarm: The FD800 inverter has a fault diagnosis function, which can promptly detect and alarm various operational abnormalities or faults. It should also have corresponding protection functions, such as overcurrent, overvoltage, and undervoltage protection, to ensure the safety of equipment and personnel.

Remote Monitoring and Management: Through the integration of Modbus with the monitoring system, remote monitoring and management of the drainage system can be achieved, enabling timely detection and handling of problems, and improving operational efficiency and reliability.

5.Customer value

By introducing the FD800 inverter technology, the municipal strong drainage facilities can achieve the following customer benefits:

Enhanced energy efficiency: The FD800 precisely controls the operating parameters of the equipment, reducing energy consumption and lowering operating costs.

Improved stability: The FD800 optimizes the system operation, enhancing the stability and reliability of the equipment, reducing the failure rate, and extending the equipment's service life.

Enhance flexibility: The FD800 frequency inverter can dynamically adjust the operating parameters of the drainage system according to actual needs, adapting to different drainage requirements and enhancing the adaptability and flexibility of the system.

6.TAG

The application of the FD800 frequency converter provides a new solution for the upgrading of municipal strong drainage facilities and will inject new vitality into the sustainable development of urban drainage systems. We look forward to the municipal strong drainage facilities achieving more efficient and reliable operation under the guidance of frequency converter technology, providing better guarantees for the development of the city and the quality of life of residents.
