What is the Most Economical Pressure in Pneumatics?

Bits and Pieces - Fluid Power Fact #1: What is the Most Economical Pressure in Pneumatics? Pneumatic systems have been developed and progressed comparatively as a low-pressure system. Pneumatic air consuming devices such as cylinders and rotary actuators are designed for the maximum operating pressure of 8 to 10 bar [115 to 145 psi]. However,... Continue Reading →

Hydraulic Fluid Contamination & its Control

Hydraulic fluids are subjected to various kinds of contamination. Contaminants can affect the physical and chemical properties of fluids. If the contaminants are not monitored or controlled, the fluid is likely to be subjected to various kinds of failures. These failures include the deterioration of the fluid properties and consequent fluid breakdown. At the system... Continue Reading →

How to Develop Multiple-actuator Pneumatic Circuits Using the Cascade Method?

Most of the practical pneumatic systems involve the use of multiple actuators (cylinders, semi-rotary actuators, etc) which when operating in specified sequences carry out the desired control tasks. Double-pilot directional control (DC) valves are used as final control elements to control the forward and return strokes of the actuators. Sensors are used for confirming the... Continue Reading →

Relay-based Electro-hydraulic Systems

[You may download this article at: https://fluidsys.org/downloads/ ] In the electrical actuation of a hydraulic valve, the necessary actuating force is obtained electrically with the help of a solenoid. The off-centre core of the solenoid coil is pulled towards the centre of the coil when the electric current is passed through it. This discrete movement of the... Continue Reading →

Hope you are able to recall the functions, circuits, and applications of pressure control valves. Pressure control valves are used in hydraulic systems for obtaining pressure-related control functions.... Continue Reading →

Hydraulic Filters

The article explains the constructional features,  location-specific installation details, and performance specifications of hydraulic filters.  Introduction Modern high-pressure hydraulic systems with components built to closer tolerances are susceptible to many types of contamination. Contaminants can cause the premature wear of internal surfaces. They also promote leakage and clog the flow paths. Therefore, an efficient and... Continue Reading →

Load Sensing Hydraulic Systems

[ You may download this article at: https://fluidsys.org/downloads/ ] A conventional hydraulic system with a fixed-displacement pump provides a constant flow through the system. When the system develops the set pressure, the pump flow is bypassed through the associated pressure relief valve. As a consequence, the system generates tremendous amount of heat. Even when a variable-displacement pump is... Continue Reading →

Electro-hydraulic Servo Valve Systems

[ You may download this article at: https://fluidsys.org/downloads/ ] Hydraulic systems driven by servo valves provide highly accurate control over enormous forces. A servo valve system consists of a transducer, a servo amplifier, a servo valve, and an actuator with a connected load. It is a closed-loop system used for the precise control of the...
