INTRODUCTION of AIR COMPRESSOR in Pneumatic system.An air compressor is a mechanical device that transforms power into pressurized air using an electric motor, gasoline or diesel engine.It operates by drawing in air, compressing it, and then storing it in a tank at a higher pressure. This compressed air can be Read more…
Learn solenoid valve and its working principle. How its coil energized and work in lock,valve.Learn electro magnetic. What is solenoid in Physics? Introduction When we hear the word “solenoid”; our minds may conjure images of complicated mechanism and complex electrical systems. However, fundamentally, a solenoid is a simple yet remarkable Read more…
Shutoff valve in pneumatic system is used to open or close the path.It has 2 ports and 2 positions.It may have a lever or handle to open and close the valve. Shutoff valve Symbol More details about Shutoff valve-Here.
Viscosity is the fundamental property of a fluid that describes its resistance to flow. Viscosity remains one of the most interesting and mysterious concepts in fluid dynamics. It can be viewed as a gauge of a fluid’s thickness or thinness. What exactly is viscosity? We refer to the tendency of Read more…
Example,diagram and application of hydraulic actuators.Types and principle and parts of hydraulic actuators. What is a hydraulic actuators? This is a mechanical device which transfer the force created by hydraulic fluid to some useful purpose. What are the types of hydraulic actuators? Two types-Linear and rotary. Linear-Cylinder piston Rotary-Hydro Motor Read more…
Difference between Pneumatics and Hydraulics systems,actuators,cylinder,machines,pressure gauge and symbols. Differentiate pneumatics and hydraulics system Pneumatic system Hydraulic system 1-Pressure developed by compressor. 1-Pressure developed by pump. 2-Pressure can be stored. 2-Pressure is used immediately. 3-Pressure can transfer upto 1000m. 3-Upto 100m only. 4-Air flow because of pressure difference between source Read more…
There are three types filter in hydraulic system.Suction filter or strainer,inline filter and return line filter. Strainer Suction filter restrict contamination of suction oil for pump. Inline filter Inline filter clean the oil after pump before component. Return line filter Return line filter clean oil after component and before return Read more…
When the inlet pressure of pump is reduced to the vapour pressure of the oil,the liquid get vaporized and cavity formed.This is called pump cavitation. Cavitation may take place when oil sucked into pump is not sufficient to fill the space created by pump rotational element. Cavitation in pump causes/symptoms Read more…
The function of flow control valve is to regulate the speed of actuators/piston/hydro motor. Unit of oil flow is LPM-Litre Per Minute. The volume of oil deliver per unit time is called flow.The oil flow can be controlled by flow control valve. In this valve the oil flow path or Read more…
Types,purpose,working principle,diagram and trouble shooting of direction control valve in Hydraulic system. Purpose of Direction control valve in hydraulic system DCV are used to control the actuators.For example-Forward and reverse movement of piston can be controlled by DCV. Direction control valve can be divided into two types Sliding spool type Read more…
