HOSE MANUFACTURE CONTAMINENTS

05.01.2019

  Hydraulic systems require clean, contaminant-free oil for efficient and reliable operation. Contaminants can come from a number of sources and find their way into the system which is why filters play an important role.   The pressurised oil can quickly carry the contaminants through the entire system causing premature failure of components, internal leakage and power losses.   Many contaminants are produced at hose manufacture stage. Whether they be for new systems or replacement in old systems - all...

HYDRAULIC COOLING SYSTEMS

02.06.2019

With a long hot summer in progress, and several more weeks of hot weather anticipated, it’s a good time to share some thoughts on cooling hydraulic systems. Where does the heat come from? Most users are familiar with the phenomenon of power loss in the hydraulic systems they operate – in simple terms, the difference between the energy put into the system and the energy that comes out as usable power. But of course the power is not really “lost” – the “missing” energy just gets turned into another, unusable form of...

Understanding Heavy &...

When enquiring about adaptors or hose ends with metric thread, we here at Gerrard Hydraulics will always ask if the thread is metric heavy, metric light or screwing into a port or manifold. The latter will be discussed later but first, we’ll take a look at what metric heavy and light are all about. Metric hydraulic fittings come in a range of standardized thread sizes. These thread sizes are usually available in both a heavy and light series. The heavy series is for a smaller tube OD with a thicker wall. The light series for...

DIY Repairs &...

Think twice before repairing and installing your own hydraulic equipment. Many people think that they can repair and install their own hydraulic equipment. However, it does not always turn out the way they plan. They believe they can save a buck or two by trying to do it themselves. For instance, the above hydraulic motor was leaking, so the owner decided to repair it himself by welding it up to stop the leak. If he had proper training and understanding of hydraulic components, he would know welding on a cast iron housing...

Hydraulic Pumps: How It Works

05.11.2018

Hydraulic Pump A hydraulic pump converts mechanical energy into hydraulic energy. When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system. A pump produces liquid movement or flow: it does not generate pressure. It produces the flow necessary for the...

Everything You Need to Know...

Hydraulic motors are one of many mechanical components that make your machinery work the way it's supposed to. Here, we look at what hydraulic motors are, and why they're important. What are Hydraulic Motors?  A hydraulic motor converts hydraulic energy into mechanical energy; a rotating shaft. It uses hydraulic pressure and flows to generate the required torque and rotation. You can use hydraulic motors for many applications, such as winches, crane drives, self-propelled farming equipment, excavators, mixer and agitator...

It’s that time of year again when farmers are busy planting the seeds for their crops, using purpose-built machinery. Since a successful crop production is dependant on the seeding process, ensuring your site is properly prepared, and you’re using the best possible hydraulic machinery for planting your seeds, is a must! What's the Seeding Process? Seeding, as the name suggests, is when farmers plant the seeds that will ultimately grow their crops. This process could be completed by hand if you’re only working with a...

Why You Should Get Extra...

02.01.2018

We often get enquiries in regards to adding an extra set of remotes on the back of tractors for easy cross over from one hydraulic circuit to another. For example, you have a tractor with only two sets of remotes and you are towing your air seeder that has 3 functions (2 wing lifts and a main lift). With the 6 port diverter fitted to one remote set you now have a 3 remote outlet. Now you simply connect the solenoid to an electrical switch in the cab and by turning the selector on/off you can operate two functions from...
