Trucks and heavy equipment Poclain In major projects and harsh environments.. downtime is not an option! 🏗💥 The Zoomlion ZE385G excavator is considered one of the excavation giants and heavy-duty task performers in construction and mining sites in the Kingdom. But this immense power and high productivity depend entirely on the core of excavation: the complex hydraulic circuit and the main motion pump. The power and efficiency of this excavator lie in its intelligent Positive Control Flow Pump system, equipped with the giant Hengli V90N-180 pump. What is the advantage of the Positive Control system in the V90N 180 pump? 🤔 Unlike traditional systems, the Positive Control system relies on precise electrical control signals sent directly from the ECM, which in turn receives electrical signals from the pressure sensors related to hydraulic signals for precise and efficient control of the oil flow rate, thus directly controlling the speed of movements and achieving significant fuel savings. To clarify, this is done as follows: Instant response without waste: The pump only pumps the effective amount of oil actually needed by the operator, preventing energy loss. Low heat and higher efficiency: Reduced back pressure to the tank, protecting the circuit components from thermal wear and maintaining optimal oil viscosity under heavy working pressure. Challenging maintenance and complex tests Maintaining this advanced system does not rely on guesswork; it requires extreme precision and a deep understanding of electronic and hydraulic control signals (Electro-Hydraulic Overlapping). We at Global Hydraulic Power excel in handling this complexity: ✅ Resetting and calibrating the excavator pump control: The Positive Control system relies on the extreme precision of electrical signals and internal hydraulic signals within the pump. It is calibrated correctly and as needed to operate at maximum efficiency. ✅ Complex tests and Factory Reset: We don't just do mechanical repairs; we test the equipment under maximum operating pressures, adjust pump flow angles and main relief & port relief valve pressures to precisely match the original factory settings 100%. The result? Smooth, fast movements, and no excess load on the engine.
