Avoid These 5 Common Hydraulic System Mistakes

Reduce the need for hydraulic repair or troubleshooting by understanding hydraulic principles.

Avoid These 5 Common Hydraulic System MistakesMistakes, oversights, and misconceptions about how a hydraulic system works result in problems all the time. Fortunately, you can get expert help addressing these problems from Bernell Hydraulics. Whether your system is just acting a little funny or is totally inoperational, we can diagnose the problem with informed troubleshooting and provide the necessary repair. We’ll even provide advice to help you prevent experiencing the problem again in the future if possible.

Here are 5 common mistakes we find leading to problems for our customers.

Mixing Up Flow and Pressure

Flow and pressure are certainly related, but it is still important to measure them separately in order to properly assess what’s going on in the system. It’s also important to understand how the placement of flow or pressure valves can affect readings. For example, if a flow control valve is installed inline, it may have an effect on backpressure which may make it appear that the flow control valve is actually regulating pressure. If you don’t understand what’s really going on in this relationship, you won’t be able to create and maintain an efficient system.

Not Providing More Power for More Flow

Customers often want bigger pumps to provide more flow. However, they sometimes resist also purchasing a bigger motor. In reality you cannot achieve more flow with a bigger pump alone. You must invest in the total package in order to create the additional input power that will be required to pressurize a greater flow of fluid.

Thinking a Bigger Pump Provides More Force

When it comes to the force that is produced in a hydraulic system, it’s all about the cylinder, not the pump. Pump size does not affect force—it only affects how long it takes to generate the force you need to accomplish your task. If you want more force you need a new cylinder.

Not Accounting for Double Acting Cylinders

Double acting cylinders are useful in that they can generate force on the extension and the retraction portion of the movement. However, it is important to remember that these two forces are not equal. In a double acting differential cylinder, the rod always moves more quickly but with less force on the retraction than on the extension.

Not Understanding Stresses on Hoses

One final error is not understanding the stresses your system is placing on your hoses. This can be very disruptive to your business because frequent hose failures will put your equipment out of commission. While eventually all hoses will wear out, most causes of premature hose failure are entirely preventable with a little foresight.
