Why Phasing Cylinders are...

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...

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 the one...

What are Quick Release...

In hydraulic fluid power systems, power is transmitted through an enclosed circuit via fluid under pressure. Quick release couplings or QRC’s (also known as quick-action couplings, quick connect couplings, break-away couplings, just to name a few) are used to join or separate fluid conductors to or from a circuit. There are just as many types of QRC’s as there are manufacturers. Thankfully, there is an international standard to which the manufacturers conform to. The International Organization for Standardization (ISO)...

How to Diagnose a Faulty...

Do you have a creeping bar and think a phasing cylinder might be at fault? How do you determine which cylinder, if any, is the faulty one? Unfortunately, diagnosing a faulty phasing cylinder isn't always as simple as identifying the moving cylinder. Why? Because the moving cylinder isn't always the culprit. Below is a handy diagnostic chart that shows, while under load, the interaction between good cylinders and faulty ones. Need help identifying the condition of your phasing cylinders? Or maybe you just need...

14 Little Known Facts About...

Unfortunately, hydraulics isn't a topic that most people are knowledgeable on. So, to try and increase the level of awareness and knowledge surrounding this niche topic, we've put together 14 little-known facts about hydraulics and hydraulic equipment.    Hydraulic power is nearly always generated from mechanical power. Example: A hydraulic pump driven by an engine crankshaft. Hydraulic power output is nearly always achieved by converting back to mechanical energy. Example: A cylinder, which raises a heavy...

Oil Viscosity – Everything...

Here at Gerrard Hydraulics, we stock and sell two grades of hydraulic oil, 46 and 68. But what do these numbers actually mean and how do you determine which one you need? The numbers 46 and 68 refer to the ISO Viscosity, and all hydraulic oils sold in Australia use this number grading system. Viscosity is oil’s resistance to flow and the grading system relates to this resistance at a temperature of 40 °C. These numbers can be thought of in this way: the lower the number, the thinner the oil and the higher the number the...

Dowerin Field Days are Coming...

This year the Dowerin Field Days are on August 30th and 31st. This event is the largest agricultural expo in WA. Over the two days, everything agriculture and farming community-based products and services will be on display. If you’re new to the event or a regular you will find us at our usual site No. 384, on the hockey oval. Each year we display a large selection of the products and services we offer here at Gerrard Hydraulics. Our staff will be available across both days to answer questions and help with any queries...

What Should You Do at the End...

With the seeding season reaching its end, in the coming month your machinery will be working hard day and night. Has your equipment not worked as efficiently as expected, but you persisted with it anyway? When your crops are fully sown you may be thinking its time to put the equipment away until next year, but don’t be too hasty. Now is a good time to get the airseeder fan drive motor serviced due to leaks or inefficiency, or perhaps your bar cylinders need to be resealed due to creeping or external leaking. Whatever the...

cylinder intensification in hydraulics

Cylinder Intensification in...

When defining pressure intensification in hydraulic cylinders, it all comes down to the total scope of the surface differential between the surface area of the full bore end, and the usable surface area in the rod end. The usable surface area in the rod end is commonly known as the Annulus surface area. The annulus area is calculated by subtracting the rod diameter surface area from the bore diameter surface area. The full bore end surface area is always larger than the annulus area. Intensification occurs in hydraulic...
