As one of concrete mixer machine, electric concrete vibrator is a device by means of power through certain devices as a vibration source to generate frequent vibrations, and this sort of vibration is passed to the concrete to vibrate tamping concrete equipment.
In general, there are a wide variety of concrete vibrators. According to the transmission, which can be divided into internal type(insert type), external type(attachment type), flat type, etc. In terms of the vibration of the form, which can be divided into planetary, eccentric, reciprocating, and so on. According to the Power of vibration source, which can be divided into electric, internal combustion, pneumatic, hydraulic, etc. By the vibration frequency (2000 ~ 5000 times / MIN), ntermediate frequency (5000 ~ 8000 times / MIN), high-frequency (8000 ~ 20000 times / MIN) and so on. The internal type (insert type) has three kind types including the soft axis planetary type, the soft axis eccentric type and the direct-coupling type. Moreover, the common external type (attachment type) is the attachment type and the flat type.
Brief concrete vibrator structure (1) Flexible shaft insertable vibrator is composed of motor, transmission, vibrator, etc.
(2)The direct-inserted vibrator is composed of a vibrating rod and a set of inverter units. (3) The attachment vibrator is a three-phase bipolar motor made of special cast aluminum alloy shell, with a disc-shaped eccentric block on each of the two protruding ends of the rotor shaft. When the electric Poplar drives the eccentric block to rotate, the vibration force is produced by the torque of the eccentricity.
(4) The platform vibrator is composed of the upper frame, the lower frame, supporting springs, motors, gear boxes, vibrators and other components.
