Internal High frequency vibrator with built in converter

Description

 construction equipment, internal high-frequency vibrators with a built-in converter typically refer to vibratory compactors or concrete vibrators. 

1. Vibratory Compactors: These are machines used to compact soil, gravel, or asphalt during construction. They use a vibrating mechanism that helps settle and compact the material more effectively than static compaction methods. The vibratory compactor typically includes an internal mechanism that converts the rotational motion of the engine or motor into high-frequency vibrations that are transmitted through the compactor's base plate or rollers.

2. Concrete Vibrators: These are tools used to consolidate freshly poured concrete to remove air bubbles and ensure uniform distribution of the concrete mix. Internal vibrators (often called immersion or poker vibrators) are inserted directly into the concrete mix. They have an internal mechanism that converts electrical or mechanical power into high-frequency vibrations, which are transmitted to the concrete.

The "built-in converter" you mentioned likely refers to the mechanism within these machines that converts the power from the engine (for vibratory compactors) or from an external power source (for concrete vibrators) into the high-frequency vibrations needed for compaction or concrete consolidation.

EWO Electric High Frequency Internal Vibrators, which are directly connected with the mains supply at 230 V, 50/60 Hz, consist of a tractor unit called vibrator head, 10 metres of electric cable and of 5 metres internally reinforced operating hose

​An Internal High-Frequency Vibrator with Built-In Converter is an advanced concrete compaction tool that integrates a high-frequency motor and a frequency converter into a single, portable unit. This design eliminates the need for external converters, simplifying setup and enhancing mobility on construction sites.​

⚙️ Technical Specifications

• Vibration Frequency: Typically around 12,000 vibrations per minute (vpm), ensuring efficient concrete consolidation.​

• Vibrator Head Diameter: Varies by model; for instance, the EWO series offers diameters ranging from 38 mm to 65 mm, while Wacker Neuson's IRFU57 model features a 57 mm head.​

• Centrifugal Force: Models like the EWO series deliver forces between 1,700 N and 7,330 N, facilitating deep and uniform compaction.

• Power Supply: Designed to operate on standard single-phase power supplies, such as 230 V or 120 V, depending on the model.​

• Protection Features: Equipped with safety mechanisms like thermal overload protection and IP66-rated enclosures to guard against dust and water ingress.​
