A complete range of 36 textbooks, in Paperback & Kindle eBooks Editions, on Pneumatics and Hydraulics, under Fluid Power Educational Series, authored by Joji Parambath has... Continue Reading →
Hydraulic fluids are subjected to various kinds of contamination (particles, water, air, compounds, and biological matters). 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. A complete range of 36 textbooks, in Paperback &... Continue Reading →
Modern hydraulic applications demand compact machines designed with tighter tolerances and that run at faster cycle times. They are designed to work with small amounts of fluids. They operate at higher pressures, temperatures, and speeds. Under these circumstances, fluids are subjected to severe stresses. Hydraulic Fluids By Joji Parambath The textbook presents information on the... Continue Reading →
A programmable logic controller (PLC) is a modern device that can be used to control the work process in a machine or an appliance. The operations involved in the work process are carried out by some kind of actuators such as electric motors, pneumatic actuators, hydraulic actuators, etc., which are in turn controlled by final...

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 core is used to actuate the...

Introduction Modern high-pressure hydraulic systems with components built to closer tolerances are susceptible to many types of contamination. Contaminants... Continue Reading →
Textbook on ‘Load Sensing Hydraulic Systems in the SI Units’ By Joji Parambath The textbook presents information on the classification, constructional features, working, and essential terms and definitions, sizing, and safety and maintenance aspects of hydraulic accumulators. The book uses the SI system of units. Textbook on ‘Concepts of Load Sensing Hydraulic Systems in the... Continue Reading →
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 output (load) parameter, such as position, velocity, or force,... Continue Reading →
A hydraulic accumulator mainly consists of a chamber in which a fluid is held under pressure by a spring or a raised weight or a volume of compressed gas (nitrogen). It is, thus, possible to store potential energy in the accumulator, when the associated system pressure is greater than that of the accumulator. A hydro-pneumatic... Continue Reading →
