Brief Introduction of Pneumatic External Vibrator
Pneumatic external vibrator is widely used in water conservancy and power worksite, high-rise construction, mining, underground buildings and roads, railways, bridges with beams, T-beams and precast plants and other large precast concrete vibration chamber work, thereby reducing the clotting time of concrete, improving the strength, but also can be installed on a variety of vibration devices as a vibrating source.

Product Principle of Pneumatic External Vibrator
Pneumatic external vibrator is powered by compressed air while driven. It produces mechanical vibrations by outputting torque, driving mechanism for the planetary rotating movement.

Features of Pneumatic External Vibrator
1. It features small size, light weight and easy operation.
2. The frequency and the exciting force are adjustable.
3. It has no danger of explosive in the gas place, meanwhile no influence in harsh environments such as high temperature.
4. It has overload protection, without failure due to overload.
5. It has a high starting torque, can directly start in the condition of load.
6. It has strong water resistance, not afraid of moisture.
7. With a diesel engine, it can be operated in the construction areas without electricity.
8. No bearing can reduce routine maintenance and avoid bearing wear problems at high speed operating conditions.

Features and Differences of Pneumatic External Vibrator
1. The actual power performance is exactly same with the nameplate marked.
2. The only one product in the domestic market, which is made of cast iron casing, makes the amplitude effect better than aluminum products.
3. Amplitude frequency is adjustable. The exciting force is 1.5 times that of other similar products.
4. The whole weight of the product is 1.3 times that of other similar products.
5. High-frequency vibration source device is the only product, which obtained the patent for invention in domestic market.
