Hebei Guanneng’s GNLW554 horizontal decanter centrifuge has been officially put into operation at an overseas municipal wastewater treatment plant, providing efficient and stable sludge dewatering solutions for the facility. The complete integrated system consists of the core dewatering centrifuge and a customized intelligent control cabinet realizing fully automatic, unattended sludge treatment and greatly optimizing the plant’s waste disposal efficiency.
The GNLW554 centrifuge adopts high-strength duplex stainless steel structure with excellent corrosion resistance, fully adapting to complex overseas sewage working conditions. Equipped with high-precision rotor and differential system, the equipment delivers powerful solid-liquid separation performance, effectively reducing the moisture content of sludge cake and minimizing sludge volume for convenient transportation and landfill. Its wear-resistant spiral design ensures long-term stable 24-hour continuous operation, meeting the plant’s large-volume and continuous sludge treatment demands.
The supporting GN intelligent control cabinet acts as the core brain of the whole system, undertaking nearly 40% of the system’s core functions. Adopting IP55 waterproof and dustproof stainless steel enclosure, it is specially optimized for humid and harsh wastewater workshop environments. Integrated with industrial PLC, duaVFD inverters , the cabinet realizes real-time monitoring and closed-loop automatic adjustment of key parameters including rotating speed, differential speed, feed volume, vibration and temperature.
With built-in multi-dimensional safety interlock protection, the cabinet triggers audible and visual alarms and automatic shutdown in case of overload, overheating and abnormal vibration, effectively protecting the centrifuge. It supports one-click switching of automatic and manual modes, stores operational data and alarm records, and can be seamlessly connected to the plant’s DCS system. Reserved remote diagnosis ports enable remote parameter calibration and fault troubleshooting, greatly reducing overseas maintenance costs and downtime.
The combination of reliable mechanical performance and intelligent control system makes GNLW554 an ideal choice for overseas municipal sludge treatment, further enhancing Guanneng’s brand influence in the global environmental protection equipment market.
