High-Strength Excavator Hydraulic Oil Tank

The high-strength excavator hydraulic oil tank is a crucial component for ensuring the efficient operation of the excavators hydraulic system. In heavy-duty environments such as mining and construction, it must withstand continuous vibrations and pressure. It is made of 3mm thick cold-rolled steel plate, laser-cut with precision to ensure blank size errors are within 0.5mm. Subsequently, a CNC bending machine folds the three-dimensional structure of the tank, with rounded transitions at the bending angles to reduce stress concentration. The welding process utilizes argon arc welding robots to continuously weld the tank seams. After welding, a hydrostatic test is performed to ensure no leakage under 1.5 times the working pressure. The interior is phosphated to form a protective film, preventing oil contamination; the exterior is coated with polyurethane wear-resistant paint to resist gravel impacts on the construction site. It is suitable for 20-30 ton excavators, providing a stable hydraulic oil reserve for their high-intensity operations.
