Understanding Pressure Compensation in Hydraulic Systems

June 19th, 2019

Pressure compensation systems operate a little like feedback-based electronic systems. That’s not exactly a surprise, not when hydraulics circuits can become every bit as complex as any electronically based wiring. At any rate, the similarities are there for everyone to observe. When an output change occurs, a fraction of that change is sent back to […]

Why Bearing Alignment is Critical to Pump Life

June 3rd, 2019

Bearing alignment difficulties impact all shaft-driven systems to some degree. In a ventilation fan, a poorly aligned bearing will shorten the lifespan of the appliance, and then a cool room will fill up with stifling heat. Noise, screeching vibrations, all kinds of nasty headaches will crop up until the fan stops working. With pumps, though, […]

Key Components in Filtration and Conditioning of Hydraulic and Pneumatic Pumps

May 15th, 2019

Just like a healthy circulatory system, hydraulic fluids perform more efficiently when they’re cleaned and conditioned. A person feels weary if their kidneys aren’t doing their job. Likewise, an unresponsive mobile hydraulics system can probably blame a fouled-up fluid contaminant. Knowing this, a repair engineer checks the hydraulic oil. If that oily medium is fouled […]

Understanding Parker Pumps Medium Pressure Industrial Piston Pumps

May 6th, 2019

Parker provides a large range of medium pressure industrial piston pumps. Predictably, since this is one of the most recognized names in the hydraulics sector, each series packs a host of performance-tuned features. To achieve this feat, the Parker Pumps engineering chiefs have divided their medium pressure products into four groups of intermediate-strength piston pumps […]

What is Hydrostatic Leak Testing in Pumps?

April 15th, 2019

If fluid pressures power hydraulic components, the tests used to inspect those system parts should also be fluid-based. That’s just common sense. Accordingly, engineers employ their finest hydrostatic leak testing paraphernalia when they’re running fluid circuit punctures to ground. So far so good, then, but what is hydrostatic leak testing all about? From question to […]

Hydraulic Pressure Intensifiers: How Do They Work?

April 4th, 2019

Hydraulic systems are impressive constructs. Arguably speaking, they’re even more sophisticated than an electrical circuit. In point of fact, most modern fluid-based systems include electrical and electronic elements, which either add regulatory control or feedback signals to the equipment. Among that mass of performance-engineered components, hydraulic pressure intensifiers perform their own unique services; they provide […]

The Importance of Accurate and Well-Maintained Filtration System in Pumps

March 25th, 2019

When you operate a pump, it is of the utmost importance that you take care to keep it properly functioning. Pumps can be hardy machines that work to keep a pool filled or to keep an outdoor water feature flowing. In either situation, your pump needs to be able to reliably filter out all of […]

Why Pneumatic Systems are Ideal for Hygienic-Sensitive Applications Such as the Food Industry

March 8th, 2019

Machines and hygiene-sensitive applications are not naturally compatible. Generally speaking, oily machines and dirty mechanical gears should be kept far away from the food industry. To quash such food hygiene issues, system designers have ousted the many moving parts and assemblies that form conventional machine architectures. In place of those pollutant-plagued assemblies, they’ve built a […]

Understanding Open and Closed Loop Systems in Fluid Power

February 26th, 2019

Let’s cut straight to the meat of the article. Open loop fluid systems start by sending a fluid stream through the system inlet, where it’s then picked up and boosted by a hydraulic pump. The hydraulic oil leaves its reservoir, passes through a pump outlet port, and it’s channelled towards an actuator or another active […]

Factory Pump and Valve Assembly and Testing: Meeting Pump Curve Accuracy

February 14th, 2019

In hydraulics equipment, factory-branded pump and valve assemblies are put under a big microscope. Well, the instruments aren’t optical microscopes, but they do analyze the performance of these key system components in great detail. Needless to say, the graphs produced by these analytical programs look quite outlandish, at least that’s how they appear to a […]
