The photovoltaic pile driver in Anhui, after long-term operation, appears to be running slowly and with stiff movements. This aging condition is primarily due to poor maintenance of the hydraulic system. It's known that in the use of solar photovoltaic pile drivers, the hydraulic oil will inevitably be exposed to dust and fine particles. Over time, the accumulation of these particles is natural, and the presence of water vapor from long-term operation is also a normal occurrence. Moreover, water droplets can corrode the hydraulic system, similar to how ants corrode. For any structure, long-term operation, high temperatures, and low heat dissipation are also invisible killers.
