Zhonglian Pump Truck Radiator Fan 4-wire Variable Frequency 2-line Regular Model Hydraulic Oil Cooling Machinery Parts

Intelligent frequency conversion, on-demand heat dissipation: adopting a 4-wire design, supporting PWM or voltage signal speed regulation. The fan can automatically adjust its speed according to the temperature of hydraulic oil or coolant, running at low speed during low load to save energy and reduce noise, and running at high speed during high load to ensure heat dissipation, avoiding the energy waste of traditional fans that operate at full speed or stop. Efficient heat dissipation, ensuring system stability: specially designed for the cooling of pump truck hydraulic systems and engines, with large air volume and high air pressure, it can quickly remove heat, effectively preventing system efficiency decline or component damage caused by high hydraulic oil temperature, and ensuring the continuous and stable operation of equipment under heavy load conditions. Dedicated for special vehicles, seamless replacement: tailor-made for Zhonglian pump trucks, the installation hole positions and interface specifications are completely consistent with the original factory, and old parts can be directly replaced without any modification. Some models are also compatible with pump trucks from brands such as Sany and XCMG, with strong universality. Sturdy structure, suitable for harsh working conditions: The fan blades and protective net are made of high-strength engineering plastics or metal materials, which are resistant to high temperature, impact, and corrosion, and can resist dust, oil pollution, and rainwater erosion on construction sites, ensuring long-term reliable operation in harsh environments. Reduce noise and improve operating experience: The intelligent speed regulation function avoids the fan running at full speed for a long time, significantly reducing the noise during equipment operation and providing a quieter and more comfortable working environment for operators.
