Eccentric concrete vibrator is equipped with an eccentric shaft in the poker head, and the eccentric shaft rotates at high speed to generate centrifugal forces, which is transmitted to the concrete vibrator through the bearing to make it vibrate. Its main feature is that the vibration frequency generated by the vibrator is equal to the rotational speed of the flex shaft. Because its vibrating poker head is comparatively shorter compared with pendulum vibrator, eccentric concrete vibrator is more suitable for some shallow depth which need high frequency vibration, such as slabs, forms, precast, etc. Moreover, the noise generated by this vibrator is relatively low, so it is suitable for working occasions where has strict requirements of noise level. The concrete vibrator used in construction site is high-frequency vibrator. In order to make the vibration frequency of eccentric vibrator reach 200Hz, the speed of the motor under load needs to reach 12000Rpm, and the speed of no-load needs to reach 15000~18000Rpm. Because the drive unit’s rotation speed is high and the wear is relatively high, in order to keep the long use life and the stable operation performance, T-Flex makes strict control to the spare parts to high quality level and the correct assembly. The well-known representative eccentric concrete vibrators brands are Wacker Neuson and Enar. The couplings designs and poker head diameters are different. T-Flex could supply both forms and divide our catalogue to ZPN-W and ZPN-E series.
