Plant Maintenance & Spare parts purchase
There was lots of pain and headache in arranging spare parts, equipments from the market. Almost three of staff boys were involved for arranging all these from the market. To make it hassle free, we focused on to explore something like going online where we could get everything at one place and at our door step too.
And at last we explored them… you can also join...
Basic Difference between Conductors , Insulators and Semi Conductors
Conductors :-Materials that permit flow of electrons are called conductors (e.g., gold, silver, copper, etc.).
Insulators :-Materials that block flow of electrons are called insulators (e.g., rubber, glass, Teflon, mica, etc.).
Semi Conductors :-Materials whose conductivity falls between those of conductors and insulators are called semiconductors.
CONVERSION AC TO DC
1 ) Determine what your AC input voltage is. In North America and parts of Central and South America, the AC voltage at most sockets is 110 to 120 volts at 60 hertz. In Europe, Asia, Australia and most of the Middle East and Africa, it's 230 to 240 volts at 50 hertz. The standard in other areas may differ.
2) Find the voltage and amperage needed to power the components of your electronic device. Check the manufacturer's instructions, if necessary. Too much of either amperage or voltage will destroy the components, while too little will not allow the device to work correctly. Most have a safe range; aim for...
Conversion of Kinetic Energy to Pressure Energy
The key idea is that the energy created by the centrifugal force is kinetic energy.The amount of energy given to the liquid is proportional to the velocity at the edge or vane tip of the impeller. The faster the impeller revolves or the bigger the impeller is,then the higher will be the velocity of the liquid at the vane tip and the greater the energyimparted to the liquid.This kinetic energy of a liquid coming out of an impeller is harnessed by creating a resistance to the flow. The first resistance is created by the pump volute (casing) that catches the liquid and slows it down. In...
ELECTRIC MOTOR PROTECTION
All electrical equipment must be protected against damage deriving from trouble or abnormal operation. The following phenomenamust be taken into consideration:
- Overcurrents deriving from short-circuiting;
- overload currents;
- break or dip in supply voltage;
- Motor overspeed.
In addition, for the purposes of safety, there needs to be protection against direct contact with live parts and indirect contact with partsnormally not live but which could become live in the event of insulation failure.
• Overcurrents deriving from short-circuiting. Protection can take the form of:...
