The highway guardrail pile driver, which is now essentially fully installed, includes a very important component – the air filter. The air filter device is used to protect the diesel engine by primarily filtering dust from the air to keep it clean as it enters the engine. If dust enters the diesel engine, it can easily lead to cylinder damage.

Recently, we encountered a customer who experienced an issue during the loading process of a highway guardrail pile driver. The air filter pipe was accidentally suspended. During the manufacturing process of the machine, a wire was found, and the pipe was hung to one side. As drilling operations typically generate a significant amount of dust, the engine started to make noise and emit black smoke in less than half a day. They didn't pay attention to the seriousness of this issue, which continued to work, resulting in very low efficiency. Eventually, after detailed consultation, the real cause was identified – damage to the air filter. The entry of dust into the diesel engine directly caused cylinder pulling in the diesel engine.

It's well known that the air filter of a high-speed guardrail pile driver is designed to operate in harsh environments. In simple piling operations, the amount of dust generated during construction is relatively small. However, particularly during drilling, a considerable amount of dust is produced. At this time, the dust enters the diesel engine along with the airflow. The protection provided by the air filter can resist external dust, ensuring the air entering the diesel engine is relatively clean and safeguarding the engine's operation.
