Highway guardrail pile drivers are especially suitable for the installation, maintenance, and emergency repair of highway guardrails in field construction projects. They are known for their high piling accuracy, durability, and efficiency. However, during construction, highway guardrail pile drivers may encounter some minor issues, such as lack of driving force or slow construction efficiency. So, what are the reasons for the low construction efficiency of highway guardrail pile drivers?

1. Poor sealing of the hydraulic cylinder in the highway guardrail pile driver. Check or replace the sealing rings promptly.

2. The oil suction filter is blocked. Remove the blockage, clean, or replace it in a timely manner.

3. Insufficient hydraulic oil. Replenish the hydraulic oil promptly.

4. The safety valve is malfunctioning or the pressure setting is too low. Replace the safety valve spring or adjust the pressure to 16MPa promptly.

5. The pump is not drawing oil. Resolve any air leaks in the oil suction pipeline or dryness in the oil suction pipeline immediately, ensuring it is filled with oil to form a vacuum.

6. Nitrogen gas leakage in the highway guardrail pile driver, resulting in insufficient pressure. Use a nitrogen pressure gauge to check and maintain the nitrogen pressure at 1.2MPa promptly.
