The use of construction machinery inevitably leads to malfunctions. Pile drivers, as frequently used auxiliary machines, often experience equipment failures. Problems with major components can affect the operation of the entire machine. Therefore, operators must understand the causes of issues, resolve them, and restore construction promptly. Here are some common faults of hydraulic cylinders in pile drivers:

1. Internal Stagnation in the Hydraulic Cylinder: This can cause the piston to slip or break. This issue arises when parts inside the hydraulic cylinder are improperly installed, deformed, worn out, or overly restricted due to public service. The root cause is the poor quality of parts and components, along with scratches on the outer surface or steel piles caused by sintering, leading to increased resistance and reduced speed. To address this problem, you need to repair or adjust the cylinder from scratch, replace damaged parts, and remove any iron filings in a timely manner.

2. Damaged Hammer Bolts: Given the harsh working environment of pile drivers, parts are prone to wear and tear. Bolt failure is somewhat normal because the hammer experiences strong vibrations during operation, loosening the protective and main bolts, leading to fatigue damage.

3. Weak Pile Driver Pump: In this situation, the inlet and outlet are reversed, with a small inlet and a large outlet. After compressing the hydraulic oil, the gear oil lacks pressure. Another issue is the internal oil seal of the gear pump being damaged, which can cause the oil seal to age and prolong internal usage time, resulting in insufficient pressure.

Understanding these common faults and their causes can help operators effectively troubleshoot and maintain their pile drivers, ensuring continued efficiency and productivity on the construction site.
