Advantages and Applications of EP Series Resonance Free Variable Frequency Variable Torque Vibration Pile Hammer

The vibrating pile hammer is one of the important equipment in pile foundation construction. It generates vibration through the rotation of an eccentric body, which can "liquefy" the soil around the pile, reduce the resistance between the pile and soil, and quickly achieve the purpose of sinking and pulling out the pile. Compared with other pile driving machinery, the vibrating pile hammer has both the functions of sinking and pulling piles, and can be used to produce prefabricated piles and cast-in-place piles.

Pile sinking and pile pulling functions

Due to its high construction efficiency, good effect, small lateral displacement and deformation during pile sinking, no damage to the pile head, and low cost, the vibrating pile hammer has always been an important member of the pile machinery family. At the same time, with the rapid development of China's national economy, vibration pile hammer technology has made great progress in China. The vibrating pile hammer is playing an irreplaceable role in China's modernization construction, and it has injected new vitality into the development of China's pile machinery industry.

High efficiency, good results, and more economical

China is already the country with the highest production and use of electric vibration pile hammers in the world. After years of development, China has reached international standards in the technology, manufacturing, and application of electric vibration pile hammers.

The EP series resonance free variable frequency torque electric drive vibration pile hammer, one of the main products of Shanghai Zhenzhong with complete intellectual property rights, uses a hydraulic control eccentric torque conversion device to continuously adjust the eccentric torque of the vibration pile hammer from zero to the maximum value during start-up, shutdown, and operation. Due to starting and stopping under zero eccentric torque, the occurrence of "resonance" is avoided, and the amplitude can be adjusted to adapt to changes in soil conditions, making it highly adaptable and widely applicable. At present, this series of products is one of the advanced products in vibration pile hammers, and the products have been exported to developed countries such as Japan.

Export to various countries

The Shanghai Zhenzhong EP series resonance free variable frequency torque electric drive vibration pile hammer has the characteristics of compact structure, convenient use, and high efficiency. It can smoothly and freely adjust the eccentric torque from "0-maximum" or "max-0" during the starting, stopping, and running processes, realizing the machine's ability to adjust the eccentric torque freely for different working conditions, soil types, etc.

The advantages of Shanghai Zhenzhong EP series resonance free variable frequency torque electric drive vibration pile hammer compared with traditional ordinary electric vibration pile hammer are as follows:

1. The machine can be started under non eccentric torque conditions with a small starting load. Solved the problem of requiring a large capacity power supply for starting ordinary electric vibration pile hammers with eccentric torque, which was previously widely used.

2. Overcoming the "resonance" caused by starting and stopping with eccentric torque, the machine can start and stop smoothly and freely. Preventing the occurrence of severe vibration noise and damage to other components caused by resonance.

3. The large vibration hammer adopts a variable frequency vibration resistant dual output shaft motor, and the drive belts are symmetrically installed on the front and rear pulleys of the exciter, which disperses and distributes the force on the shaft evenly, reduces the pressure on the bearing, and lowers the temperature rise of the bearing without being easily damaged. No resonance, environmentally friendly

In recent years, Shanghai Zhenzhong has re created the EP series resonance free variable frequency torque electric drive vibration pile hammer and successively developed EP120KS、EP160、EP160KS、EP200、EP240、EP240KS、EP320、EP320KS、EP400、EP550、EP650、EP800、EP1100、EP1600 The electric vibration pile hammer of the same model has optimized its mechanical structure, especially for large electric vibration pile hammers, making it more widely applicable and of higher product quality.

The overall structure of the large vibrating hammer has been changed from a traditional vertical structure to a horizontal structure. This new structure has a lowered center of gravity, making the operation smoother, safer, and with lower working noise; Good oil splash lubrication effect, no need to install forced lubrication device; The hydraulic oil inside the box has a large area, good heat dissipation effect, low temperature rise, and can meet long-term continuous operation. The vibration reduction device adopts a new type of independent beam structure and is directly connected to the exciter, which greatly reduces the height of the whole machine and avoids the collision between the traditional suspended vibration reduction structure and the motor of large electric vibration pile hammers; This new type of beam type vibration reduction structure is heavy and more conducive to pile sinking operations; The vibration reduction device with independent structural form is easy to connect or disassemble with the exciter, and the machine transportation is convenient.
