Downtime: It Isn’t Always BAD

Published on by Brian FarnoLeave a comment

When you say Downtime in an industrial or manufacturing setting, it may easily carry a negative connotation. This means that the output of production is not happening and input to production has halted as well. If this is not planned, it is absolutely a worst-case scenario. In our personal lives, though, downtime generally doesn’t have a negative meaning behind it. That’s the time to disconnect and recharge to maximize your output after you return to production and that is exactly what I had the luxury to do recently. This is also a message I received from a person I look up to and trust in their experiences. Vacation time can be looked at similar to a preventative and planned downtime of equipment. Without it we just wear down and eventually productivity grinds to a halt. While hanging out at a lake with my daughters this past week, I helped them hone their fishing skills. They each baited their own hooks with worms and chose their spots. We completely slayed some bluegills, and released every single one of them.

The calm of a storm rolling in when you have nothing to do is serene.

Prescribed maintenance, preventative maintenance, vacations all help to build back into the production of whatever good or service the company provides. The entire production of a facility all starts with the utilities, energy, water, compressed air, steam, other compressed gases, and the personnel. If your power input isn’t maintained, monitoring connections and disconnects, you can find yourself with a lack of service, resulting in dangerous situations. City water is often required for processes or for the facility to function properly, even an office building needs it for plumbing, fire suppression, and drinking. Steam, compressed gases and compressed air may all be required by the processes.

Servicing the compressed air where it starts is one of the most critical steps in operating a compressed air system. Making sure that your compressor has the minimum downtime, all starts with the preventative and prescriptive maintenance. One of the first tasks should always be changing and monitoring the intake air filter. Like Russ Bowman said a while back in his blog, take a deep breath, if you sneeze or smell something that is from the intake air your nose just took in from the surrounding area. That’s even after your nose hair has already partially filtered air intake. Your compressor is no different. If you let it suck up debris, dust, and pollen, then it is eventually going to have a failure. Instead of sneezing, it may burn up a vane, valve, scroll or screw. That is going to be a considerably higher cost and longer downtime than just performing the manufacturer’s listed items to maintain optimal performance.

The compressor shown above according to the caretaker receives a regular change on the airfilter every month. This is just before the cleaning and changeover. Not only do they change the filter, they make sure to clean the entire housing inside and out. That’s one of the ways this compressor has lasted with minimal downtime over the past 20 years.

Basic System Maintenance

Published on by Brian FarnoLeave a comment

Maintenance is something that can have two different forms; preventative and reactive. At home, I try to ensure I perform preventative maintenance on my major appliances. For instance, I clean the coils on my A/C condensing coils at least once a year, if not twice. I change the intake air filter on the air handler once a month because it is a 1″ thick filter, which is the manufacturer’s recommendation. When it comes to our aging vehicle fleet of two, I do a combination of preventative maintenance such as tire rotations, fluid checks and changes, as well as reactive maintenance such as thermostat replacements and sensor changes when they go bad.

Regarding industrial facilities, the same kind of maintenance can be found. I have worked in facilities where the only type of maintenance that is done is in fact reactive. You know the old adage, “If it ain’t broke, don’t fix it.” That is legit how some of these facilities I have been through function. In fact, they will take parts off a broken production line that they are waiting on the parts for and put on another machine when it breaks down just to keep something going. The inventory of replacement parts was non-existent on-site and would cause downturns due to mechanical failures often. This has resulted in low up-time scores, which also sends production costs through the roof because they are trying to make up for downed lines by running overtime and increasing speeds on the lines that aren’t down.

While preventative maintenance can seem like it is costly and troublesome because it can take a machine out of production, I assure you it is still cheaper and easier than having that emergency maintenance call that comes after hours on a Friday. This is one of the main reasons we talk about installing point-of-use filters on systems that require clean compressed air. If you start to see more than a 5 psig drop across a filter, then you should look at replacing the filter element to ensure optimal performance like the video below showcases for model 9004. Should something like a main dryer fail, these point-of-use filters will help to collect any bypass or remnants in the system from just such a failure of up-stream equipment.

If you would like to discuss other preventative maintenance steps, like monitoring the usage of a system to see leakage when it starts, or how to clean and maintain your EXAIR products, contact an Application Engineer today.

Spot Cooling, Cold Gun Promotion

Published on by Jordan T ShouseLeave a comment

Like many companies, here at EXAIR we generally always have a promotional offering.  These rotate throughout the months and this month is no different.  The current offering involves the EXAIR Cold Gun Aircoolant Systems.

These spot cooling systems help to reduce cutting fluid use, increase production speeds, increase tool life, and has helped more customers than I know.  One customer in particular is a maintenance worker from a welded tube manufacturer.  This facility had very little amount of downtime permitted due to the high efficiency and high volume of orders.  When a machine went down the maintenance team went in like a trauma team to determine the cause of failure and get it fixed to get the line back up and running. One of the biggest problems they would have is when they would have to dry machine a quick part to get the machine back up and running, this would either ruin tools or they would have to slow down the machining time to get the surface finish and dimensions they truly needed.  After talking with us the team ordered a Single Point Cold Gun Aircoolant System as these parts were generally small enough to tackle with the single cold outlet (larger parts benefit from the dual point hose kit).

They received the spot cooler system in and sure enough a machine went down.  The crew went to work and once the broken part was located they got to work on their lathe trying to make a new piece.  The Cold Gun held itself straight to the headstock thanks to the integrated magnet and the flexible single point hose kit routed the cold air straight to the cutting insert point.  They didn’t have to fill up the liquid tank or setup the mist system on the lathe, they simply turned on the compressed air and let the lathe do the work.  They were able to take what had recently been around a three hour machine job with heavy wear on tooling to a two hour job, no finish pass was needed on the part, and their tools weren’t completely spent by the end of the job.

They got the part back into the machine, made adjustments, and then went to work getting the machine back into production.

Right now, if you would like to try out a Cold Gun Aircoolant System you can order before 12/31/21 and you will receive a free Dual Point Hose Kit with your qualified purchase.
