Masters in the construction industry know that the photovoltaic pile driver has been used for a long time, and its actions are very slow, just like an elderly person. What's the reason? It is well known that the hydraulic oil of the photovoltaic pile driver has been used for a long time, and the leakage amount is almost the same. Here, we must discuss the issue of the central rotating joint. The internal oil seal of the joint is a wearable part that needs replacement over time. Long construction periods, exposure to wind and rain, combined with the dust at the construction site entering the rotating seam, cause the central rotating seam to leak. It's no wonder that the movement of the photovoltaic pile driver is slow. Therefore, before each construction, it is necessary to carefully repair and replace the hydraulic oil tube to prevent the piston rod from bursting and turning black, to avoid defects that affect the construction period. Our company's photovoltaic pile drivers strive for perfection, from small parts to precise processing, ensuring reliable quality.
