In just a few minutes, a Sumpcleaner will vacuum up the entire contents
of a machine sump. The filter separates the solids from the coolant. Pump filtered coolant back to sump or transport for central processing.
Watch the sumpcleaner clean a dirty sump in a customer's plant.
An important part of cleaning coolant is filtration or solids separation. Filtration involves passing coolant through a
porous material that will remove the chips, swarf and fines.
Metal
chips in the coolant can mar the workpiece.
One of the functions of coolant is to wash
the metal chips away from the machine tool and cutting area. The
chips and fines follow the coolant to the sump where most settle.
Those remaining are recirculated through the machine and can damage
the workpiece by marring the finish.
Chips
and fines in coolant sumps cause microbial growth leading to stinky coolant
and dermatitis.
Most chips and fines settle to the bottom
of the coolant sump forming a sludge. This sludge promotes bacterial and
fungal growth. Biocides added to the coolant to control the growth
of bacteria do not reach the coolant that is mixed with the sludge
at the bottom of the sump.
Failure
to remove the chips and fines can reduce the coolant sump volume.
Some of the water in water-based coolant is
lost by evaporation. Coolant is also lost when it is carried out
on parts. Chips and fines settle in the sump, making the sump continue
to appear full, even though the volume of coolant moving through
the machine has been reduced.
Excessive
solids can cause increased fluid temperature.
Less coolant moving through the machine, means
less time spent cooling in the sump. Fluid is pumped back through
the machine quicker resulting in higher coolant temperatures. Also,
solids have different heat transfer properties than coolant.
Excessive
solids may deplete coolant ingredients - coolant is not as effective.
Among the ingredients added to coolant are
rust inhibitors, fungicides and biocides, wetting agents, emulsifiers
and coalescents. Solids may absorb desirable ingredients and lessen
their effectiveness. Many of these problems can be eliminated or
greatly reduced by cleaning the sump regularly. CECOR Sumpcleaners
deliver high suction lift to remove all solids in the coolant sump
along with the metalworking fluid. The filter separates solids from
the coolant for re-use right at the machine tool. Filtered coolant
is pumped back into the sump in minutes.
Save
labor costs and reduce downtime.
A pail and shovel or the machine’s internal
coolant pump may seem like the cheapest way to clean a sump, but
when you consider the hours or perhaps, even days needed for an
employee to do a thorough job, the costs mount quickly.
By
using a CECOR Sumpcleaner you can save money two ways. Save labor
costs. How much are you paying that employee per hour? High suction
lift from a CECOR Sumpcleaner sucks the sludge and the muck out
fast...much faster than a shovel. Also machine downtime is less.
How much production time and money do you lose when the machine
tool sits idle? A CECOR Sumpcleaner will reduce machine downtime
to a minimum.
Improve
Employee Morale
It sure beats a pail and shovel. When sump
cleaning is easier and faster, it will get done more often. With
regular cleaning the build-up of impacted swarf and layers of scum
in the sump will not occur and the job will be more pleasant and
faster. Regular sump cleaning will reduce the odor and mess in and
around machine tools and reduce the risk of dermatitis, making for
an overall cleaner and more productive work setting.
