With the rapid development of national economic construction, there are more and more offshore construction projects. The foundation construction of key offshore projects such as cross sea bridges, offshore wind power generation, and offshore drilling platforms has put forward higher requirements for the capacity and reliability of construction equipment pile drivers. With the application of variable frequency speed control motor products in many industries, The application of variable frequency speed control motors and frequency converters to form a speed control system on vibration pile hammers has become the development direction of electric vibration pile hammers.
The commonly used electric vibration pile hammers are mainly driven by constant speed and vibration resistant motors. Due to the non adjustable vibration frequency, the frequency of the vibration pile hammer cannot be adjusted according to the construction requirements of different geological types. With the rapid development of variable frequency speed regulation technology and the strong advocacy of energy-saving and emission reduction policies, the new electric variable frequency torque vibration pile hammer with stepless speed regulation function will have a broad market space.
The variable frequency speed control and vibration resistant three-phase asynchronous motor used for vibration pile hammers is a specialized product developed independently through reasonable material selection, special electromagnetic design, and special structural design, with the development of variable frequency speed control technology and the absorption of advanced variable frequency product technology at home and abroad and the vibration resistant technology of ordinary vibration resistant products. It is suitable for driving vibration sinking and pulling pile hammers under variable frequency speed control conditions.
The vibration pile hammer can be powered by a variable frequency variable speed and vibration resistant three-phase asynchronous motor, which can smoothly start at low frequencies, avoid the impact of motor starting on the power grid, and reduce the capacity of the power transformer. By coordinating and controlling the eccentric torque of the pile driver, the goal of infinite frequency conversion can be achieved within a wide speed range, achieving the ideal state of vibration pile sinking and pulling operation, improving construction efficiency, accelerating engineering construction speed, and achieving significant energy-saving effects.
