Using Vibration to Eliminate Frozen Screws

Using Vibration to Eliminate Frozen Screws

A Netter energy customer was using a large container in its power plant operations with a cover that was screwed into place. Due to the internal pressure of the container, the screws that secured the cover would frequently become deformed. That, combined with the introduction of small amounts of dirt, often froze the screws in place. When that happened, it was frequently necessary to bring in an outside contractor to remove the lid from the container.

The customer purchased two Netter NVT 105 pneumatic vibrators, which generated a radial motion, and a Netter NTS 50/40 vibrator, which generated a linear motion along the vertical axisThis vibration created enough separation between the male and female threads that the friction was reduced and the screws were more easily removed. The result was a substantial reduction in downtime and eliminating the cost of the outside contractor.
