There are three different states of matter have been found in everyday
life, and a fourth is not so common. They are as water, solid and gas -
with the latest plasma. Almost 99 percent of all matter in the universe
plasma, but it is less common in the soil, because it is extremely hot.
We tend to see in the sun or the form or the flash. Plasma is also used in neon and fluorescent lamps.
To understand the place occupied in the plasma membrane, first look at the states of matter in the world and its properties. The atom consists of protons and neutrons in the nucleus is surrounded by a swarm of electrons. If overheated, these electrons move very fast in random patterns and have published from their obligations to the base. When the electrons leave their link to the atom, which are negatively charged and positively charged nuclei are left as ions. The hotter than the electrons, the faster they move and leave before large amounts of energy.
The use of water as an example, is the first solid state of matter. A solid has a special form and is of neutral atoms arranged in a pattern composed loaded hex. Ice is a good example. The liquid is in the next state of matter. In this state the molecules are still together, bound, but move relative to the other very slowly. The gas is in the next state in which molecules move independently of each other at high speed and separate, so that the nuclei and negatively charged electrons are called positive ions. The plasma will be the last state of matter in which electrons and ions move so fast that when they collide with each other to produce enormous amounts of energy formed.
A plasma cutter uses this energy to your advantage. It has a nozzle with two gas passages and a center electrode negative. If cut close with power and space charge on the metal creates a very hot spark. A gas such as argon result of the disclosure surrounding the arc is extremely hot, the molecules move at a rapid pace, meet each other and release large amounts of energy. , Contain the unpredictable arc in a smaller limit, a second round of the protection of the gas stream. The plasma is cut at an incredible 30 000 degrees to - location, something. You can cut through sheet metal as thick as butter.
A typical auto plasma cutter includes: a table on which mounted a cloth such as a steel plate or the like are cut, is a drive to XYZ a plasma torch with servo amplifiers and servo motors or similar X, Y, and Z is a plasma drive cutter supply device for generating a plasma with a plasma torch, a gas supply contract unit for the supply of natural gas in the plasma torch is water cooling device cooling of a nozzle and an electrode that described in the ionized plasma torch, and a controller of North Carolina and similar institutions to a numerical control (NC) program for the transformation of an arc plasma torch supply, while the plasma-plasma torch moves relative to the material being cut.
In addition, plasma cutting machine power supply typically includes: a main inverter circuit, the electric energy supplies in an arc on the plasma-plasma torch, and ignite with a constant power supply, DC-loop, a circuit for generating high frequency superimposed on a high voltage to a pilot arc between the electrode and nozzle of the plasma torch in the output voltage of the main circuit, a circuit that the output voltage of the main circuit between the electrode and nozzle, during the pilot-arc ignition and then makes the phase of the application of the output voltage between the electrode and the workpiece so the pilot to make an arc main arc and a power control unit to the main switch, the circuit of circuits with high frequency and the pilot controlling the pilot arc, rotate and subsequently maintain the central arch supports. Understand that the CNC plasma cutter Power Device that these elements is usually contained in a single chassis contains. Although the main arc power is supplied by this type of equipment for plasma cutting power depends on the type of material being cut and thickness, etc., can reach a high value, as several hundred amperes. It is therefore necessary to create a circuit with high output capacity.
