Changing Hydraulic Filters: Timing Is Everything

Like any piece of equipment, hydraulic systems require regular maintenance to deliver peak performance across their life span. Anyone who works with these machines knows they should change hydraulic filters, but the ideal timing is often less clear. The industry is full of differing opinions and advice,...

Protect and regulate your pneumatic circuit

What is a pneumatic circuit? A pneumatic circuit is an installation made up of pneumatic elements that guide or regulate the air so that the compressed air travels to some actuators. By displacing the air we get mechanical energy. The main components of a pneumatic circuit are...

When should you use rotary actuators?

Rotary actuators, in many cases, are a hybrid of linear and rotary actuators. Of course, in the fluid power realm, linear and rotary actuators are more affectionately referred to simply as cylinders and motors, respectively. A cylinder creates linear force when pressure acts up its piston’s surface...

What is a hydraulic circuit?

A hydraulic circuit is a set of interconnected components through which fluids flow. Usually hydraulic oil. By means of these elements subjected to pressure, the displacement of mechanical components is achieved, which will make our machinery or vehicle develop the functions for which they were designed. Types of hydraulic...

Different Types of Hydraulic Pumps

Hydraulic pumps are an integral part to making the machinery work. A hydraulic pump converts mechanical energy from the pump mover when the hydraulic operates into hydraulic energy. The hydraulic energy is made up of both pressure and flow to make the actuators perform properly. The hydraulic...

What is a pressure gauge and what is its use

A pressure gauge is an instrument that indicates the pressure of the fluid in a circuit . The fluid in the circuits can be both liquid and gas; Hydraulic oil and compressed air being the most common, respectively. We use the pressure gauges for both control and regulation, or to...

Nine reasons why your pump runs slow

In a recent 2021 Fluid Power Technology Conference — Virtual Series presentation, MSOE University’s Tom Wanke took an in-depth look at Pump and Motor Troubleshooting, Failure Modes and Analysis. One problem that drives engineers and maintenance technicians crazy is when a hydraulic pump underperforms or runs erratically,...

Matching the Right Drive to Your Motor

Getting the best out of your operations means doing more than simply connecting a motor to a piece of electrical equipment. You will also need a drive to act as an intermediary, moderating the flow of power from the motor to the equipment and supporting safer, more...

How to identify the size of a hydraulic hose

Identifying the size of the hydraulic hose is very important so hydraulic system’s do not have to be altered. To measure the size we can use two nomenclatures: Nominal diameter and Inches. Hydraulic Hose Size The Nominal Diameter: also known by its abbreviation DN, is the measurement...

The Safe Operation of Hydraulic Tools

Hydraulic tools offer the user great versatility when it comes to transmitting power and controlling motion. Unfortunately, if operated incorrectly, they can become extremely dangerous: this is due to the way in which the fluid is stored under high pressure and the potential high force capability of...
