Addressing the issues encountered with pile drivers on highways involves managing wear and tear and operator errors, which are primary causes of malfunction. Many of these factors are inevitable, but they can be minimized or reduced as much as possible. For instance, the operating hours of a diesel engine need to be kept within a certain limit, and the lifespan of electrical components is finite, both of which can lead to malfunctions. However, operator errors can be mitigated through training and reminders to reduce the occurrence of faults, lessen wear and tear on other parts, and by conducting regular replacements and inspections to ensure the normal use of the pile driver on highways. To avoid construction delays, pile drivers on highways commonly exhibit weaknesses when newly put into service and during long-term use.

In new pile drivers, issues such as inadequate pressure adjustment or nitrogen charging may cause weak driving force. For pile drivers that have been in use for a long time, failures might occur due to impurities in the hammer, leading to various malfunctions. Additionally, long-term wear of the drill rod can lead to severe wear, deformation, and other failures. When the driving force of a pile driver on the highway is weak, what should be done?

First, check if the pressure gauge reading is normal. The standard hydraulic pressure for a pile driver on the highway should be 15MPa. Check the pressure corresponding to this value and adjust it if necessary.

If the pressure is normal, examine the nitrogen gas pressure. Use a nitrogen pressure testing tool to see if the nitrogen pressure is within the normal range of 10-12MPa. If the pressure is insufficient, recharge with a compatible nitrogen cylinder. If both hydraulic and nitrogen pressures are normal, inspect the oil path of the drill rod and other parts. If there are no issues with the external related parts, disassemble the hydraulic hammer for inspection. The disassembly of the hydraulic hammer should be documented via video, which can be sent directly to customers if necessary. Follow the steps in the video to disassemble the hydraulic hammer, check for, and eliminate faults. Common malfunctions in the hydraulic components of pile drivers on highways are often concentrated in external hydraulic components, and some internal faults cannot be resolved by non-professionals. For more troublesome faults, contact the original manufacturer for inspection and maintenance.
