A vacuum truck, whether it is used for residential septic service, portable toilet discharge, or something such as wastewater removal or oilfield pumping, is essentially still a vacuum truck that operates on the same basic principles. Consider the tank and vacuum pump – important indeed yet far from being the only critical parts on these trucks. There are some features that every one of these vacuuming machines should possess in order to have a safer, more efficient operation. When searching for one of these vehicles to purchase, buyers should be watchful for all of the important and helpful components to be sure of finding a good truck and making a wise financial investment, as the quality and usefulness of a vacuum truck is highly dependent on all of its parts. Composition of the Tank Almost every tank that is a part of a vacuum truck is constructed of steel, whether it is stainless, aluminum, or just standard steel plate. Each of these similar metals have different regulation thicknesses that must be confirmed to ensure each one of the components is of regulation thickness. The inclusion of flanged and dished heads and inner compartment dividers provides greater overall strength as well as creates a container that is structurally sound and will not collapse from the force of the internal built-up vacuum. Additionally, an inner baffle that is constructed of the same material as the exterior should be included in the design. Features of the Tank A well-made tank needs to include a few important features that affect everything from filling and emptying the unit to the ease with which cleaning can be done. A means of entrance of at least 20 inches that is centered on the top of the reservoir above the baffle makes the job of cleaning the interior of the container inside much easier; in addition, it is much more likely that it will be done because both sides of the center walls can be reached in this fashion. There should be at least three sight bubbles on the rear part of the tank so that watch can be maintained on how full the container is getting. If the tank design includes a separated water compartment near the front, there should also be a sight tube for the same reason. Last but not least, the means by which the container is emptied known as the dump should be located at the bottom of the rear head to facilitate the emptying process. Valves, Traps and Hose Trays The most important valve on the tank is its primary shutoff; this part should always be located near the front of the vacuum compartment at the top of the container and should be regularly serviced and maintained to ensure that it is functional at all times. A secondary moisture trap should be located near the front of the unit and must be easily reachable from the ground as it will require frequent checking for both status and emptying needs. Hose trays should run the entire length of the reservoir on both sides and be securely welded onto the tank and strengthened with structural bending if necessary. There are numerous other important parts related to the vacuum pump itself; as far as information about the vacuum tank is concerned, the details mentioned above are the components that are of primary importance in the design and construction of this large cylindrical container. The number of parts is not really that many; however, each one serves an important role in the proper functioning of the tank, helping to keep it strong and functional. Any vacuum truck should include all of the parts that are listed above; if they are not, then the vehicle is actually incomplete and it should not be considered for purchase. Each component has an essential role in making the vacuum truck the useful vehicle that it is – be sure they are all included! Christopher M. Hunter is an expert in commercial specialty trucks.
