Comparative Analysis of Vibroflotation Equipment Series 1
In the field of vibroflotation equipment, products of different technical types and models exhibit significant differences in performance parameters and application scenarios. This analysis compares four vibroflotation equipment models—BJVE-426-180 (conventional electric), BJVE-450-260 (conventional electric), BJVH-350-150 (hydraulic), and BJVEF-450-225 (electric variable-frequency)—to provide professional references for equipment selection decisions.

Comparison of Core Parameters: From Specifications to Power Performance
1. Differences in Basic Specifications
Diameter: The diameters of the four models vary significantly, ranging from 350mm (BJVH-350-150) to 450mm (BJVE-450-260 and BJVEF-450-225), with the BJVE-426-180 measuring 426mm. Diameter directly affects the equipment's adaptability to the operating environment. Larger-diameter equipment offers a wider deep vibration influence range and compaction scope, while smaller-diameter models provide stronger penetration, greater flexibility, and produce smaller pile diameters.
Power: Power ranges from 150kW (BJVH-350-150) to 260kW (BJVE-450-260). The electric variable-frequency model BJVEF-450-225 has a power of 225kW, and the conventional electric model BJVE-426-180 has 180kW. Power determines the equipment's vibration output capacity and continuous operating intensity.
2. Power and Vibration Performance
Speed: Conventional electric models BJVE-426-180 and BJVE-450-260 have a fixed speed of 1450rpm, classified as constant-speed vibroflotation equipment. They are mostly used in common soft soil foundation treatment projects.
The electric variable-frequency model BJVEF-450-225 features adjustable speed (1450-1740rpm), allowing flexible adjustment of vibration frequency according to operational needs. It is suitable for soft foundations with shallow hard soil layers.
The hydraulic model BJVH-350-150 has a wide speed range (2600-2900rpm). Its high speed enables faster vibration frequency, making it suitable for complex hard soil layers.
Centrifugal Force: Centrifugal force is the core embodiment of the equipment's "exciting force". The BJVEF-450-225 leads significantly with 520kN, followed by the BJVE-450-260 (440kN), the BJVH-350-150 (250-350kN range), and the BJVE-426-180 (280kN). High centrifugal force means the equipment can more efficiently handle high-resistance, high-load vibration operations (such as deep foundation compaction and penetration capacity in hardness soil layer).
Maximum Amplitude: Amplitude determines the "influence width" of vibration. The BJVE-450-260 has the largest amplitude at 26mm, followed by the BJVE-426-180 (22mm), the electric variable-frequency model BJVEF-450-225 (20mm), and the hydraulic model BJVH-350-150 (only 11mm). Equipment with large amplitude provides a larger radius of influence on soil compaction around the vibration area during foundation compaction construction.
