Frequency vibrator selection principle in precast prestressed concrete T-beam in
When the selection of prefabricated bridge vibrators, must address the nature and construction conditions beam shape, concrete, reasonable choice of vibration parameters and structural dimensions of the vibrator, vibration will achieve the desired effect.
Low-frequency vibrator is the past, we have been using low-frequency vibrator 2.0kw vibrator While all aspects of vibration can meet the requirements, but its biggest drawback is that quality is more important, installation and removal difficult, high frequency vibrator damage, damage after a vibrator can not be found in the case of damage or removal of maintenance workers do not appear in time, leakage vibration phenomena occur even during production, while the number of multi-vibrator acquisition also increases the cost of the vibrator due to vibration frequency is low, the template loss ring is also very serious template must use a higher vibration of thick steel plate, which not only increases the weight of the template also increases costs, but also the existence of implied 1.5kw vibrator vibration force thicker at the bottom of the beam flange inadequate phenomenon.
