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 →

Hydraulic Fluids – Functions, Characteristics, & Categories

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 must be carefully maintained throughout their service life. Three... 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 →
