of our best and oldest customers recently
asked Power Torque to review their manufacturing
process. The problem was that the conveyor
carrying their finished product would start
too suddenly, and the product would occasionally
fall off of the skids, the conveyor would
have to shut down, and each 300 pound piece
would have to be reloaded by hand, stopping
production for hours.
customer was somewhat unsure of any solution, they had been told in the past that
electric soft starts would be the way to
go. They purchased them, they failed and operated erratically. The same
thing happened with A.C. inverters. They wanted to fix their problem,
but they did not want to waste any more
money and time on something that would not work.
viewing the application, we realized that
there is a very high friction start, but
once the load was moving, the required horsepower
to run the load decreased by 80 percent.
This conveyor uses a 20 horsepower motor
with multiple reductions. The total load
on the conveyor is approximately 25,000
pounds, and it cycles on and off one time
that electric soft starts are mainly designed
for high inertia loads where the running
horsepower does not decrease abruptly, we
sized a NEXEN
that can start this type of high friction
load with a soft start, and still dissipate
the heat that builds up in a cycling application.
environment where this unit is mounted is
extremely harsh; not only is the unit mounted
outdoors, but is located just outside of
a blast furnace, where a lot of dust and
slag falls directly onto the unit.
/ Nexen has been a major line for Power
Torque for more than 35 years, and our experience
with these units has shown that they can
operate in this type of condition very well.
So our customer took our recommendation,
bought and installed the unit, and has used
it 24 hours a day without a single failure.
Our customer is very pleased, which makes
us very pleased as well. Let our experience
work for you and your company.
