What is Oxy-hydrogen cutting machine and its advantages compared with other fuel gas

Oxy-hydrogen cutting machine is a kind of oxy-hydrogen generator which used for cutting.

The principle of oxy-hydrogen cutting machine is water electrolysis from water into hydrogen and oxygen through the water separation system, cooling system and anti-backfire system,and the output mixed oxygen and hydrogen gas by acetylene rubber hose was connected to the acetylene entrance for fast cutting.

Advantages

1)Eco-friendly.

Water electrolysis make water into oxygen and hydrogen gas.It is water vapor after combustion,which is no carbon emissions rather than harmful CO and CO2 gas.

2)High safety.

It will produce gas when use and don’t produce for no use.When the working pressure is 0.2Mpa,it will automatically stop producing gas to prevent the risk of  leakage and backfire instead of high pressure fuel gas vessel. Anti-backfire device make all of gases through from water in the case of backfire, and water will put out of fire.At the same time,the pressure relief valve will automatically reduce high pressure and automatically reset in the case of backfire.

3)Oxy-hydrogen cutting without residue,firepower and quick preheating.

4)Oxy-hydrogen cutting speed is the same as oxy-acetylene,but faster than oxy-propane.

5)Energy saving.

Oxy-hydrogen flame cutting can save energy by 50% compared with Oxy-acetylene cutting and save energy by 30% compared with Oxy-propane cutting.

The Principle of Oxy-hydrogen Generator

Oxy-hydrogen generator is also called as Brown gas generator. In some industries, it is called water welding machine, water oxygen welding machine, water hydrogen flame machine, sometimes also referred to as oxy-hydrogen welding machine, oxy-hydrogen flame machine, oxy-hydrogen energy generator, etc. Actually, all of them are the device to oxygen and hydrogen by water electrolysis. 


Oxy-hydrogen generator is to convert alternative current (AC) into to direct current (DC), decompose alkaline water stocked in the electrolysis cell (H2O) into oxygen ion (OH-) and hydrogen ion (H+), in which the hydrogen ions move to the cathode of electrode to form as hydrogen (H2), and oxy-hydrogen ions move o the anode to be oxygen(O2).

The formation of hydrogen and oxygen in electrolysis cell through the device of cooling and safety ( that is anti-backfire device) processing, and pass through the soft pipe to torch. Then open the valve of the torch, you can use lighters or electronic lighters. The flame of oxy-hydrogen  can apply to heat, cut, weld or mix with other fuels to burn. It can apply in cutting, heating and welding. According to the different industrial application, oxy-hydrogen generator can be reformed to apply in other industries, such as catalyzing combustion for oil to improve its combustion efficiency, cleaning carbon for automobile engines and etc.

New high-tech carbon cleaning method brings a good news for car engine

“Saving fuel by 5%~15% and recovering horsepower by 10%~20% for your car, this is the most advanced carbon cleaning maintenance device in the world -
Okay Energy oxy-hydrogen carbon cleaning machine for car engine.”
Experts of hydrogen industry have introduced,
“Every car needs to do engine maintenance after running each 5000km, one is to change engine oil and another is to clean the carbon deposit. These 2 points are same important
for car engine maintenance. ”

Carbon deposition is the deposit after incomplete burning of mixed fuel oil and blow-by of lubricating oil. traffic congestion let cars be in a state of low speed and idle speed,

it aggravates the formation and accumulation of carbon deposition. “Carbon deposition brings a large damage: 1. Decrease the engine efficiency; 2. Increase fuel oil consumption;
3. cool starting with difficulty; 4. Excessive exhaust emission; 5. Knocking, noise of low speed
and speed-up, it will damage the piston and crankshaft.” Yunhao Qiu said, carbon deposition
is not only harmful to car,but also to humans and the environment we lived. The pollutants of
automobile discharged have become the main source of air pollution.

Okay Energy oxy-hydrogen carbon cleaning machine for car engine is the new high-tech
carbon removal way aftertraditional chemicals foam and drip additive carbon cleaning method, it certainly will be the mainstream trend of auto maintenance industry in the future. "The ignition
propagation speed of hydrogen is 4.85 m/s which is five times faster than gasoline, especially
the flameout interval of hydrogen is only 0.06 seconds which is one-third of gasoline. The
smaller flameout interval can make the flame spread to any corner of the cylinder, even reach
to the inside gap of the piston ring, the original carbon deposit can be cleaned in a short time,
and new deposition will not be produced." Experts explained more, “By Using Okay Energy
oxy-hydrogen carbon cleaning machine, the cost is only 1/30 of traditional chemicals additive
carbon cleaning method."

This is a very competitive product in the future, and it has attracted great attention in the industry.

Advantages of Oxy-hydrogen generator(water cutting machine) in carbon steel cutting

At present, oxy-hydrogen generator (water cutting machine) have been known by the carbon steel industry. and is beginning to replace some traditional gas cutting method as for its prominent superiority.
The water cutting machine can be wide application of mental,steel,copper pipe cutting etc.

Compared with acetylene,propane etc, its advantages are mainly reflected in the following respects:
(1) Compared with acetylene and propane flame, oxy-hydrogen gas flame is concentrated. 
      Preheating time is short in the same energy condition
(2)Compared with other fuel cutting, the affect zone of oxy-hydrogen flame is small.
(3) Oxy-hydrogen gas cutting machine is barely have hang slag, cutting section have a good vertical.
    The following left picture is Oxy-hydrogen Cutting, the right picture is acetylene cutting.

(4)Oxy-hydrogen generator( water cutting machine) has no pollution, no black smoke when burning, 
it is environmental friendly and not harm for people’s body.

Oxy-hydrogen generator(water cutting machine): 
2H2+O2à 2H2O, only water vapor generated (it just formed water vapor) in the cutting process, 
no any carbon emissions.

Acetylene cutting: 
2C2H2+5O2à4CO2+2H2O, there is carbon dioxide emissions.

Oxygen-propane cutting: C3H8+5O2à 3CO2+4H2O, there is carbon dioxide emissions.
Furthermore, Hydrogen gas is non-toxic and tasteless but acetylene, propane and other industrial gas include sulfide 
lead compounds and etc. harmful substances, they will cause respiratory disease if workers inhaled.

(5) Energy saving effect is prominent.
A) Oxy hydrogen gas generator (water cutting machine) uses water and electricity, electrolyze water into H2 and O2, 
no need gas cylinder, this way saves the cost of gas cylinder leasing fees of handling and storage.
B) Oxy-hydrogen generator (gas cutting machine) produces some low pressure oxygen by itself, preheating oxygen 
can be saved, there just need some hyperbaric oxygen.
