AI Technical Summary
When the hydraulic cylinder force control of a traditional tailings filling pump is unstable, it can lead to shaft wear, reduced swing arm accuracy, misalignment between the guide pipe and the filling conveying cylinder, tailings leakage, shortened equipment lifespan, and increased maintenance frequency.
A pressure relief valve is added between the oil cylinder and the oil pump, and the overflow port is connected to the oil pump tank through the return pipe to adjust the hydraulic system pressure in real time and ensure stable output force of the oil cylinder. At the same time, hydraulic drive and double pin shaft connection are adopted to optimize the swing mode of the swing arm and avoid impact and jamming. A stirring motor is installed on the outer wall of the filling tank to prevent tailings from clumping.
It achieves continuity and stability in tailings transportation, reduces leakage and wear, extends equipment life, lowers maintenance costs, and improves operational efficiency.
