H&Z-VB Series electric vibrators manufacurer

In the usual H&Z VB Series electric vibrators not coated with elastic elastomer, when suction and discharge of fluid are performed by vibrating the H&Z VB Series electric vibrators 2, the are disadvantages are that the amplitude thereof is small, the performance is inferior, noise occurs, and stresses are imposed on the fixed part of the vibrator so that the vibrator may be broken. On the other hand, in a H&Z VB Series electric vibrators according to the present invention which is coated with elastic elastomer layer 10, there are the advantages of layer amplitude and higher performance because the elastic elastomer layer coating the vibrator 2 is secured to and within the casing 1 so that the vibrator is suspended in the elastic elastomer. Insulation characteristics are excellent because fluid does not come directly in contact with the H&Z VB Series electric vibrators, noise is lower, and stresses are not directly imposed on the H&Z VB Series electric vibrators. Therefore the electric vibrator 2 is difficult to break because the H&Z VB Series-electric vibrator 2 is not secured directly to the casing.
Further, the deformation of the elastic elastomer along the pump casing 1 results in a remarkably reduced clearance, preventing the H&Z VB Series-electric vibrator from breaking by colliding with the casing. Therefor, the self-suction ability of the H&Z VB Series-electric vibrator pump is improved.
