Abnormal Vibration Amplitude Of Electric Vibratory Pile Driver

electric vibro hammer Abnormal Vibration Amplitude

If the vibration amplitude decreases: This usually results in reduced pile driving efficiency or even failure to drive piles. Common causes include motor rotor imbalance, bearing wear or insufficient lubrication, and power supply voltage fluctuations.

If the vibration amplitude is excessive: This fault can lead to equipment damage or excessive impact on the pile foundation. Causes may include excessive motor load, loose equipment structure, and control system malfunction.

electric vibratory hammer Motor Overheating

Overload: When the motor operates under overload conditions, it cannot effectively dissipate heat, leading to increased temperature.

Cooling System Failure: Fan malfunction, radiator blockage, etc., can affect the motor's heat dissipation, resulting in overheating.

Motor Winding Short Circuit: A short circuit in the windings will cause excessive current, resulting in a rapid increase in motor temperature.
