Product Specifications

Technical details and manufacturing context for Concrete Vibrator

Definition

A concrete vibrator is a mechanical device employed in construction to consolidate freshly placed concrete by eliminating entrapped air and ensuring uniform distribution of aggregate particles. This process enhances the concrete's density, strength, and durability while improving surface finish and reducing permeability. The device typically consists of a motor, a flexible shaft, and a vibrating head that is inserted into the wet concrete. The motor generates high-frequency oscillations, which are transmitted through the shaft to the head, causing it to vibrate. These vibrations reduce internal friction between concrete particles, allowing the mix to flow more easily and settle into formwork, while air bubbles rise to the surface and escape. Concrete vibrators are available in various configurations, including electric, pneumatic, hydraulic, and gasoline-powered models, to suit different job site conditions. Key parameters to consider when selecting a vibrator include head diameter (25–75 mm), frequency (12,000–15,000 Hz), amplitude (0.8–2.5 mm), shaft length (3–10 m), motor power (0.5–2.2 kW), and weight (5–15 kg). The operating pressure for certain models is specified as 1.0–1.6 MPa, and the maximum operating temperature is 60°C. Ingress protection ratings range from IP54 to IP65, indicating resistance to dust and water jets. Materials commonly used in construction include steel, rubber, and plastic. It is essential to verify model-specific values and standards with the legal manufacturer or supplier, as the figures provided are typical ranges for directory reference only. Proper use of a concrete vibrator is critical to achieving structural integrity and a quality surface finish in concrete construction.

Working Principle

The vibrator generates high-frequency mechanical oscillations through an eccentric rotating mass or pneumatic/hydraulic mechanism. These vibrations are transmitted into the concrete mix via a vibrating head, reducing internal friction between particles. This allows the concrete to flow more easily, filling formwork completely and forcing entrapped air to rise to the surface.

Frequently Asked Questions

What is the typical head diameter range for a concrete vibrator?

The head diameter typically ranges from 25 to 75 mm, depending on the model and application. Always verify the exact specification with the manufacturer.

What frequency does a concrete vibrator operate at?

The vibration frequency is typically between 12,000 and 15,000 Hz. This high frequency helps in consolidating concrete effectively. Confirm the specific frequency for your model.

What are the common power sources for concrete vibrators?

Concrete vibrators can be powered by electric, pneumatic, hydraulic, or gasoline sources. The power source affects portability and suitability for different job sites. Check the manufacturer's specifications.

What is the maximum operating temperature for a concrete vibrator?

The maximum operating temperature is typically 60°C. Exceeding this temperature may degrade insulation and affect performance. Always follow the manufacturer's guidelines.
