    What Components Make up a Hydraulic Tank?

    A hydraulic tank is essentially a large reservoir with a series of valves, an air drain, a regular drain, and a filter.

    What Does a Hydraulic Tank Do?

    A hydraulic tank contains the hydraulic fluid for any piece of hydraulic machinery. Whenever you shut down the system, all the remaining liquid will drain back to a central point in your reservoir.

    Additionally, the tank bleeds the hydraulic system of any air bubbles by releasing air through a valve. Last but not least, the reservoir filters hydraulic fluid. This ensures that the hydraulic system can operate efficiently by removing air and debris and storing fluid that’s not in use.

    How Does a Hydraulic Tank Work?

    A hydraulic tank can be a pressurized system which forces the hydraulic fluid out of the rest of the system. It can also be non-pressurized and rely on gravity to bring all the liquid to the reservoir.

    Once the fluid is there, the tank allows contaminants to settle, heat to evaporate, and air to escape. A pump then recirculates the fluid to necessary parts.

    What Happens If You Have a Faulty Hydraulic Tank?

    If you have a faulty hydraulic tank, it could turn into an entire host of complications. Firstly, if your reservoir were to crack and spring a leak, you’d face the risk of a myriad of damaged parts.

    Secondly, if some of the valves don’t function correctly, the tank may also leak. Furthermore, a faulty reservoir may allow dirt and debris into the system, causing various problems with other machine parts.

    Finally, if a tank happens to be faulty, it could allow air into the system and wreak havoc on the machine.

    How Do I Know If I Need to Replace a Hydraulic Tank?

    When you discover excess fluid in various parts of your vehicle, your reservoir may not be functioning adequately. The same could be true if you have too much air in the system or dirty hydraulic fluid.

    However, air could be the result of a leaky tube after the fluid leaves the tank. Furthermore, it might be possible to replace a valve or filter rather than the entire tank.

    It would be best if you only considered replacing the reservoir when it can’t be repaired or has started to disintegrate. In many cases, it will be cheaper and easier to replace only the faulty part.

    How Do I Choose a Hydraulic Tank?

    Fortunately, choosing a hydraulic tank isn’t a complicated process. You can only fit out your machine with a reservoir that matches its existing hydraulic system.

    As a result, your choices are narrowed down significantly. You can choose between a pressurized and non-pressurized system, depending on the capacity of your vehicle. You also have to decide whether you want a reservoir with internal components, or if you prefer them on the outside where they’re easily accessible.

    There are a few different design options as well, but these mostly differ from an aesthetic aspect.
