Avoiding Missteps When Using Pile Drivers

The performance of construction machinery determines construction efficiency, while the use and maintenance of the equipment by operators and managers are closely related to the equipment's lifespan. These factors are closely linked to the economic efficiency of project construction. Therefore, we remind pile driver users to adhere to usage standards and reasonably avoid mistakes.


Common Mistakes and Their Impact:

Mistake 1: Random Selection of Fuel

This practice reduces engine lifespan, increases the likelihood of damage, and exacerbates low-temperature issues in winter. Poor diesel fluidity and increased viscosity make injection difficult, resulting in poor atomization, worse combustion, and decreased engine power and efficiency. Therefore, light diesel with a low freezing point and good ignition performance should be chosen in winter. Generally, the diesel freezing point should be 7-10°C lower than the lowest local temperature of the season.


Mistake 2: Ignoring Environmental Conditions

Severe consequences of low-temperature load operation include serious wear on the diesel engine due to premature load running. When the engine is cold, oil viscosity is high, making it difficult for oil to reach friction surfaces, leading to severe wear. Additionally, springs such as the plunger spring, valve spring, and injector spring can break due to cold brittleness. Thus, after starting the engine in winter, it should idle at a medium-low speed for a few minutes until the coolant temperature reaches 60°C before applying load.


Mistake 3: Excessive Lubrication

Many people believe that more oil is better when lubricating. In reality, excessive oil not only increases power consumption due to higher rotational resistance of the crankshaft but also leads to oil foaming, emulsification, and leakage, causing poor lubrication. Therefore, it is best to lubricate the pile driver's components appropriately without overdoing it.
