What are the Telltale Signs of Contaminated Onsite Fuel Tank?

Do you have this hunch that your onsite fuel tank is possibly contaminated by some kind of microbial growth or presence? But you are not so certain about it? Even if you are observing a regular maintenance program for your fuel tanks, the risk of running into some kind of trouble will remain — perhaps on the verge of being inevitable. 

While you can opt for your tanks to be checked annually, there is a good possibility that major things could happen in between those time gaps. If you want to veer away from expensive issues with regard to your fleet, you must know exactly what to look out for and when you need to take action when something amiss came up.  

The Main Symptoms of Onsite Fuel Tank Contamination 

A contaminated fuel containment system usually has 3 types of main symptoms, from the tank to vehicle down to fuel symptoms — we would be able to track our path through the issue itself. You can do this when you have a good outline of what you need to keep an eye for at each point. 

It is of paramount importance that you know what these symptoms are. The earlier you spot them on, the better because it gives you a chance to act sooner on the problem. This way you can keep the possibility of costly fuel tank damage at bay.

1. Equipment failure or engine problems

If you are observing regular maintenance checks on your fuel tanks and part of your drill is to inspect or check out the fuel itself, you’d have a good chance of identifying the first telltale sign of contaminated fuel tank, and this has something to do with engine trouble.  

Are you currently experiencing problems with your vehicle engines for no apparent reason? Does this involve a sudden loss of power or the performance you’ve observed is poorer than before? Are you seeing involuntary changes on the engine speed, spluttering or loss of power to accelerate? All these mentioned here are signs of contamination in fuel tanks. 

You also need to keep an eye on blocked filters, which will eventually necessitate you to have your vehicle serviced more often than not. If you have been observing any or all of the above, then it comes to follow that you need to have your fuel tested for possible contamination. You may need to have your fuel tank system checked for any possible damage.  

2. Fuel tank erosion 

If you are under suspicion that a serious, urgent issue is looming on the horizon, trust your gut feeling and take action right away. Do this by inspecting your fuel and tank at the earliest possible time. One of the most tangible signs of fuel contamination for a containment tank is the actual fuel tank erosion itself.  

If contamination in your liquid fuel is high enough, it will eat away your containment tank itself. And if this is visible already, it is an indication of severe contamination already. Therefore, drastic actions should be underway. 

3. Fuel Appearance

You need to get your fuel tested for contamination and diesel bugs. You can take this measure on your own also and just look out for possible symptoms such as diesel bug growth or water contamination.  

Under normal conditions, your fuel should have a bright and clear appearance. Otherwise, its cloudy looks like a clear indication of water contamination. If you are in this scenario, it will necessitate immediate treatment to keep the possibility of bacterial growth down and to keep bugs from developing. 

Bugs will take on the appearance of a film of sludge. They usually appear underneath the water, at the bottom part of the tank. Therefore, if you are on a quest for indicating symptoms of fuel contamination, see to it that you will not skimp on this part, taking some samples from your tanks bottom part, too.  

If you found any signs of sludge presence in your onsite fuel tank, check out its color. Dark looking sludge may well indicate hard particles are forming here, like asphaltenes. These can induce trouble to your vehicle engines since they run the possibility of blocking your filters eventually impacting its overall performance.  

Checklist for CNC Cutting Machine Preventive Maintenance

What usually comes to mind when you hear the words “preventive maintenance” for CNC cutting machines? If you understand the real value of these pieces of equipment to your business interests, shutting them out of production is enough to make you cringe just at the thought of it. 

If you happen to own such pieces of industrial equipment for your business and you are meticulous enough to know that good upkeep practices are essential to optimize their longevity and thus maximize their production value for your company, you will understand that proper maintenance and care for it is part and parcel of making them last longer. 

Below is a compilation of some of the most effective preventive maintenance tips that will surely make your CNC machine cutting tools run at their peak performance while keeping an unplanned downtime situation at bay.  

Daily Care and Maintenance Tips for Your CNC Machine

  • Make it a habit to always check out the hydraulic pressure and see that it is set at 4.5 MPa. 
  • Check out also the hydraulic fluid and determine if they are just at the right level. 
  • Inspect your chuck pressure, this should always be at the right operating pressure. If you deem it is necessary to grease your chuck, always follow the manufacturer’s recommendation on this part.  
  • Replenish your lube level whenever needs, and see to it that your machine does have adequate amounts of it. 
  • If your CNC cutting machine for wood, steel, or for any material you may use it for, is equipped with its cooling mechanism, make sure that the cooling unit is always set at the right operating level. 
  • Make it a habit to clean and clear the chip pan of chips. 
  • Always practice cleaning the window of the door and light, this should help see what is inside your machine.  
  • You need to wipe clean your stainless steel way covers. Lubricating them with hydraulic is highly advised so they will move smoothly. 

At the lapse of 40 hours, get your filter out from the CNC control cabinet and thoroughly clean it. By this measure, you will optimize the air flowing through it which will help in cooling the machine down.  

Every Quarter of the Year 

At the end of 3 months, which is equivalent to about 500 hours, make it a habit to observe the following: 

  • Inspect the chip conveyor chain and apply grease to it as necessary. 
  • Check out your machine’s coolant tank filters and clean them as necessary.  

Every Six Months

  • Six months would be equivalent to 1,000 hours. During this time, you will need to reach out to your local distributor to carry out the following preventive maintenance measures. 
  • Check out the coolant tank for the presence of chips, sludge, and oil. 
  • Drain the hydraulic tank and replenish the hydraulic oil with something new and fresher. Additionally, you will also need to have it’s suction filter replaced. 
  • Clean the radiator and see to it that its fins are straight. 
  • Drain and clean out the lubrication unit before applying a fresh way lube. 
  • If your machine comes with its cooling unit, you can have it drained and refilled.  
  • Verify your machine’s leveling and make necessary adjustments. 
  • Check out your machine’s wipers and look for any fray or damage. They should be replaced immediately if they are damaged.
