So How Does it Work?
Surge Busters® work as a liquid energy absorption for tanks. It is important to have the required number installed in a given tank because they compliment each other in the surge reduction process. Let’s look at an example of a truck that is coming to a stop and creating a significant amount of liquid surge in the tank as the trucks breaks are applied.
In the typical truck with no baffles, as the truck comes to a stop, the liquid keeps moving forward and pushing against the front wall of the tank. This energy is the transferred through the rest of the truck wearing on the breaks, shocks, engine and the rest of the running gear. This wear and tear is very hard on components and increases maintenance costs over an extended period of time. Aside from the wear to the tractor and trailer, the weight in the tank shifts dramatically and puts the driver and others on the road at an increased risk due to a possible rollover. NOTE: The force generated in the tank is equal to the force that must be absorbed by the rest of the truck.
In a truck with traditional baffles installed in the tank, the same amount of force is generated by the moving liquid but is spread between the baffles. This energy is still transferred from each baffle to the rest of the rig but is spread out more evenly to the entire truck. This energy is easier to handle when evenly distributed but still places the equipment under significant strain. Although better than not having any baffles, this scenario is still unstable and poses the increased potential for a rollover accident. NOTE: The force generated in the tank is still equal to the force that must be absorbed by the rest of the truck.
Liquid Energy Absorption
When our Surge Busters® are introduced into a liquid tank, they float in the top 1/3 of the tank and work in concert with each other to form a surge reduction system.
As the truck slows down and the liquid begins to slosh and move toward the front of the tank, our Surge Busters® suspended in the liquid move as well and congregate at the focal point of the surge energy. This baffle system begins to bend, flex and then recoil against the surging liquid, absorbing the energy in the process. These individual pieces work together as a large “shock absorber” for the moving liquid. This process happens very quickly and in every direction the liquid might be moving inside the tank. Once the truck comes to a stop, the opposite movement of liquid toward the back of the truck is greatly reduced and comes to rest much faster than with traditional fixed baffles. NOTE: The force generated in the tank is mostly absorbed and only a small percentage is then transferred to the rest of the truck.
