We have all done it: dragged our feet across the carpet wearing certain shoes or socks to build up a static charge and then touched someone to give them a jolt. While there are not enough current or amps in a static shock to do any real harm, it can have up to 25,000 volts! That’s a lot of power in your fingertips.
In this issue of the Service Advisor we look at static electricity in the plant and why proper grounding is critical. Also, be sure to read about the free offer at the end of the newsletter!
The Importance of Grounding and a Giveaway!While most static shock incidents will not cause you any permanent injury, they can cause damage to equipment and electronics and even an explosion under the right conditions.
When working on the electronics of a sorter or the controls of a vibratory conveyor (shaker), make sure you always wear a grounding strap. The grounding strap must be grounded to an earth ground either directly such as a heel strap, or through a wrist strap to a piece of equipment that has an earth ground.
Large ungrounded metal objects can accumulate a great amount of static charge. The movement of a shaker bed, for instance, will increase its accumulation of static electricity. If it is not properly grounded, you will be in for the shock of your life! All shakers are manufactured with grounding straps to prevent the build-up of static electricity. These grounding straps come in many forms including solid copper wire or a braided cable connected between the bed and frame. However, due to the nature of the bed movement, these straps have a high tendency to wear and fail. They are unsanitary and can harbor bacteria.
A couple of years ago, Key introduced a stainless steel grounding arm specifically to address the issues of breakage and sanitation. Using finite element analysis our team of engineers developed a unique arm using stainless steel that dissipates the stress through the arm rather than the mounting location. This patented, sanitary design is available as a replacement for all arm sizes (8”, 10”, 11”, 12” and 14”) through our Parts Sales team.
For a limited time, we are offering customers a COMPLIMENTARY grounding arm, just complete this form telling us where to send it and what size you need.
