Essential Insights to Consider Prior to Purchasing a Hydraulic Tank

Hydraulic tanks, also referred to as hydraulic oil reservoirs or hydraulic fluid tanks, play a pivotal role in the operation of any hydraulic system. Regardless of the term used, these tanks are critical components that require careful consideration before making a purchase. Understanding these key aspects of hydraulic tanks can save you from potential headaches, wasted time, and avoidable expenses.

When constructing a hydraulic reservoir, manufacturers often take shortcuts without your knowledge. Unless you’re well-versed in hydraulic systems, it's easy to assume all tanks are similar when, in fact, they may not be. The external designs may appear identical, but the internal construction and materials are what truly matter. To ensure you are investing wisely, consider asking these critical questions before acquiring a hydraulic tank for your system:

Are all hydraulic reservoirs subjected to pressure testing?

Many hydraulic tank manufacturers neglect to pressure test every single unit they produce. Instead, they perform random tests on selected units. Without knowing which specific tank will be shipped to you, there's a chance it could have an undetected defect. Conducting thorough pressure testing on all hydraulic tanks is the only foolproof way to ensure they won't leak.

Do your hydraulic tanks contain anti-vortex features?

Anti-vortex capabilities are crucial in maintaining the integrity of the hydraulic system. When the pump inlet sucks in fluid, it can create a turbulent swirling motion akin to water draining from a sink. This swirling can introduce unwanted air into the hydraulic fluid, which poses significant issues. Always verify that any hydraulic tank you consider is equipped with anti-vortex technology; if it isn't, it's best to look elsewhere.

Are diffusers included in your hydraulic oil tanks?

It's vital that your hydraulic tank includes diffusers. Some manufacturers may skimp on this feature, which is detrimental. Diffusers are essential because they aid in cooling by evenly distributing heat throughout the hydraulic oil reservoir. Additionally, they help isolate entrained air from the fluid and work to prevent reintroduction of contaminating particles into the system.

What welding techniques are employed in your manufacturing process?

The durability and strength of hydraulic tanks and their components greatly rely on appropriate welding practices. The continuous vibration from heavy hoses connected to the flanges can lead to metal fatigue and a potential breakdown. If you're acquiring an aluminum hydraulic reservoir, make sure they implement TIG welding for flanges, as it offers superior strength compared to MIG welding. TIG welds can be recognized by their distinctive 'stacked dime' appearance.
