I. Integrated Explosion-proof and Leak-proof Electrolyzer Technology of Walker Hydrogen Oxygen Water Welder
As shown in FIG:
a. The electrolytic cell on the left is a conventional electrolytic cell of a hydrogen production system. It is composed of two thickened end electrodes, as well as numerous intermediate electrodes and sealing rings. There is a sealing ring between any two electrodes, and the electrode is filled with electrolytic liquid. Therefore, if the sealing ring fails, the electrolyte and the generated gas will leak from the damaged or aging sealing ring, just like a home faucet Leaking the same reason.
b. The electrolytic cell on the right is Walker Energy ’s patented electrolytic cell for hydrogen and oxygen machines. What you are seeing now is the shell of the electrolytic cell. All the electrode plates are enclosed in stainless steel cylinders. Since the electrode plates are not directly external, they do not exist Leak problem.
2. Wet-wet combined dual-effect flame arrester technology for Walker oxyhydrogen water welder
Dry flame arrester principle:
The dry flame arrester is generally used in the gas pipeline outside the machine. Its core is a thing called a nano-metal flame arrester. It is made by a special sintering method to ensure that the tube body is filled with numerous small holes. The diameter of the small hole is about 20um. Because the flame cannot pass through such a small hole, the flame can only burn on the outer side of the fire-blocking tube, and cannot reach the inner side through the fire-blocking tube.
Due to the high temperature of the oxyhydrogen flame, if the gas source is not cut off in time, if the oxyhydrogen flame burns outside the firestop tube for a long time, the temperature of the firestop tube will be heated to more than 500 degrees, and this temperature point will automatically ignite the firestop. The hydrogen and oxygen on the inner wall of the tube caused the flame arrester to fail.
Some people think that buying a dry flame arrester can prevent the hydrogen and oxygen gas from tempering. This is wrong. The main reason is that the gas source was not shut down in time after the tempering occurred.
Therefore, in the equipment equipped with a dry hydrogen and oxygen flame arrester, a wet flame arrester is also required.
Principle of wet flame arrester:
Wet flame arresters, also known as water seals, refer to the emergence of gas from the bottom of the water. If there is tempering, the principle of water can be used to stop the fire.
Although the principle of dry flame arrester and wet flame arrester is very simple, the simpler things and the lower the reliability, it seems that if high school students only learn things from textbooks, if they do n’t ask a teacher to make up lessons, they will not be able to pass the exam. the University.
Walker Energy is good at solving all kinds of complex problems, and the reliability of preventing tempering can reach 99%. Generally, tempering will produce a strong, sharp tempering sound, which is easy to scare the user, and the tempering will produce High pressure of about 0.8Mpa.
See how Walker Energy addresses these complex tempering issues:
1. Electronic dry-type hydrogen and oxygen flame arrester technology for Walker Energy hydrogen-oxygen water welder
It is well known that flames like lasers are generated during tempering. Walker Energy uses laser detection sensors to detect such fake lasers in real time. 火焰因为没有后续气源供应而自动熄灭，从而实现高效可靠阻火。 Because we use a 64-bit 8G high-speed processor (computer CPU), the detection accuracy can be captured within 0.01 seconds of the occurrence of tempering. At this time, the temperature of the outer wall of the flame arrester basically only rises to 80 degrees, and the control system immediately The gas source is cut off, and the flame is automatically extinguished because there is no subsequent gas source supply, thereby achieving efficient and reliable fire suppression.
The electronic dry flame arrester of Walker Energy Oxygen Machines plays an effective role in high-risk operations where tempering often occurs, such as cutting. Because the height of the steel plate is different during cutting, the surface of the steel plate has slag or severe rust, which will cause red burning. The hot metal bounces back, blocking the cutting nozzle and causing tempering. Therefore, if there is no reliable flame arrester, the operation will not be continuous and may even cause the operator to be unwilling to operate such equipment. However, the Walker oxyhydrogen water welder's electronic flame arrester is excellent. The performance was silent during tempering, and almost no tempering occurred.
2.Wetfire flame arrester technology of Walker Energy Hydrogen Oxygen Water Welder
The difference between the wet flame arrester of Walker Energy Hydrogen Oxygen Welder and ordinary wet flame arrester lies in the following aspects:
湿式阻火器为多罐多层，而不是普通的单罐单层，相当于多级湿式防回火。 a) The wet flame arrester of Walker Energy Hydrogen Oxygen Water Welder is a multi-tank multi-layer, instead of the ordinary single-tank single-layer, which is equivalent to multi-stage wet-type anti-tempering.
湿式阻火器内置了自动泄压阀，当压力超过0.3Mpa时，自动泄压，当压力低于0.3Mpa时，自动关闭。 b) The wet flame arrester of Walker Energy Hydrogen Oxygen Machine has a built-in automatic pressure relief valve. When the pressure exceeds 0.3Mpa, the pressure is automatically released. When the pressure is lower than 0.3Mpa, it is automatically closed. Each tank is provided with an automatic pressure relief valve.
湿式阻火器内置了单向阀，当回火产生压力时，单向阀临时将气源切断，使得火焰没有气源而自动熄灭，更何况水也能自动灭火。 c) The wet flame arrester of Walker Energy Hydrogen Oxygen Machine has a built-in one-way valve. When the tempering generates pressure, the one-way valve temporarily cuts off the gas source, so that the flame automatically extinguishes without a gas source, let alone water can automatically extinguish the fire.
的湿式阻火器也是绝对安全的。 In summary, the wet flame arrester of the Walker Energy Hydrogen Oxygen Machine is also absolutely safe. In particular, the dual-effect anti-tempering technology combined with wet and dry makes the safety of the Walker oxyhydrogen machine at the peak of the industry. This technology was created by Walker Energy.
前置防回火氢氧火焰枪技术 Third, the front anti-temperating oxygen-oxygen flame gun technology
The key to the use of the oxyhydrogen welding machine is the gun. Why do you say that. There is an old Chinese saying: "If a worker wants to do his thing, he must first sharpen his weapon." For the stable combustion of the hydrogen and oxygen gas produced by the hydrogen and oxygen machine, a well-designed oxygen and hydrogen flame gun is required.
The stability of hydrogen and oxygen combustion has a lot to do with the design of the mouthpiece. One is the material and size of the mouthpiece, and the other is the aperture and number of the mouthpiece. One of the most critical issues is to ensure that the pressure of the gas from the mouthpiece is greater than 0.01Mpa to prevent the flame from burning in the mouthpiece. However, in many cases, such a situation occurs. The mouthpiece is all right when it is used. After a period of use, the mouthpiece will not work. For various reasons, the mouthpiece of the mouthpiece will become larger. Sometimes the fire is in the fire. The inside of the mouth burns, so the fire mouth must be replaced in time. Tempering if not replaced in time.
Well, tempering is unwilling to occur during use. Therefore, to avoid the accident of tempering is to design a device that can stop the fire in the place of the gun.
Walker Energy's front-end flashback oxyhydrogen flame gun technology satisfactorily solves this problem. The following are the design points of Walker Energy's front anti-tempering oxyhydrogen flame gun technology:
It is very simple to say, it is to add a flame arrester between the nozzle and the valve. This flame arrester serves two purposes.
First: accidental tempering during operation can be prevented.
Second: When the operation is completed and the fire is closed, the valve is directly closed. The oxygen-oxygen flame is tempered because the pressure is as low as zero. Then, the flame arrester in front of the valve can effectively prevent the flame.
The second point mentioned above is very important, and it is emphasized here. If there is no such front flame arrester, when the fire is turned off, each tempering will return to the position of the air outlet of the gas valve. Because the gas valve has a sealing ring, this sealing ring cannot withstand high temperature, and the tempering temperature is 2800 degrees. After one or two temperings, the sealing ring of the gas valve burned out, and the gas valve leaked. After each tempering, the gas valve could not close the fire and returned to the inside of the machine.
There is also an ancient technique of shutting down the fire, which is to connect the oxygen interface of the flame gun with compressed air here. When shutting down the fire, use compressed air to blow out the flame, and then close the gas valve. This method is also safe, but the problem is At this time, it is not convenient to directly turn off the fire, and it is inconvenient to require compressed air.
In summary, Walker Energy's hydrogen-oxygen flame gun technology of this front flame arrester not only solves the problem of tempering during use, but also solves the problem of tempering off the fire, and the operation is simple and safe. This technology was created by Walker Energy.
4. Graphic touch screen and 32-bit CPU chip control technology
Walker Energy's equipment uses a touch screen diphtheria and the interface graphically displays the status of various internal components on the interface, and the operation can be directly pressed by hand. The system status is directly displayed in text, graphics or voice mode, and the operator only needs to learn the operation of the device in one minute.
So let's take a look at what the traditional equipment looks like.
The equipment on the left uses a common operation interface, the mechanical meter displays the current and voltage, the boat switch starts, and the LED indicator alarms.
So now the problem comes. Pressing the knob is invalid. Is the machine broken or the knob is broken and the alarm light is broken. How can we determine whether the equipment is working normally or abnormal? If it is not normal, I ca n’t see what the alarm light indicates. Kind of failure, how can I deal with it.
In turn, we look at Walker ’s touch screen again. If the machine fails, it will be directly displayed in text or graphics. There is no problem of sometimes showing and sometimes not showing. If the touch screen is broken, then the whole is not a black screen. It is a screen problem, and the screen replacement problem is solved.
In summary, Walker's oxygen and oxygen machine equipment uses a 32-bit CPU control + touch screen graphic operation interface. Operating the oxygen and oxygen machine is as easy as operating a mobile phone to make calls and a computer to access the Internet. Of course, it is the best user experience and the most favorite Equipment.
V. Pulse resonance high efficiency electrolytic power supply technology
We say that the hydrogen oxygen machine is composed of five major modules: 1. electrolytic cell system, 2. anti-tempering system, 3. power system 4. control and operating system 5. flame gun and related accessories. Among them, the power system is the core component that determines the stability and efficiency of the hydrogen and oxygen machine.
The conventional oxyhydrogen machine power supply uses a constant current switching power supply or electroplating power supply, and its output is direct current. The voltage and current are generally constant. So this kind of power supply is undoubtedly very good for electroplating, because electroplating pays attention to the stability of the surface coating. However, the requirements for generating hydrogen and oxygen gas by water electrolysis are different. It requires fast and efficient production of hydrogen and oxygen gas, not slowly.
To understand the principle of Walker Energy's pulse resonance electrolysis, we must first understand how water turns into hydrogen and oxygen.
As a result, H2O becomes OH- and H + , where OH- moves to the anode, producing oxygen, and H + moves to the cathode, producing hydrogen. Obviously, we need to efficiently convert H2O into hydrogen ion and hydroxide anion, so that it is possible to produce hydrogen and oxygen quickly.
So how does H2O become hydrogen cation and hydroxide anion? Please see the schematic diagram of the microscopic process of the decomposition of water molecules into hydrogen and oxygen by the Walker Energy Hydrogen Oxygen Plant.
Experts from Walker Hydrogen Research Center explain the above pictures for you:
P1 water molecular structure diagram: This figure shows that water is composed of one oxygen atom and two hydrogen atoms. The two oxygen atoms form a certain angle with the hydrogen atom, and this angle is 104 degrees.
Diagram of the state of water molecules when P2 is not powered: Water is composed of numerous water molecules. According to scientific research, under the high-power microscope, each water molecule is disorderly, that is, some oxygen atoms are facing up, some are below, and some are On the left, some on the right, various angles are completely disordered.
State diagram of water molecules after P3 is powered by direct current (DC): After inserting the positive and negative electrodes of the power supply into the water, the positive electrode is positively charged, and the negative electrode is negatively charged. Water molecules are in an orderly state affected by the electric field.
After P4 continues to be energized, the state diagram of the water molecules : the hydrogen-oxygen bonds of the water molecules are affected by the electric field, and the hydrogen atoms are pulled toward the negative electrode, and the oxygen atoms are pulled toward the anode.
The P5 hydrogen-oxygen bond is pulled apart to generate ions and move: After the hydrogen-oxygen bond of the water molecule is stretched to a certain extent, the attractive force of the hydrogen-oxygen bond is less than the tensile force generated by the electric field. Therefore, a hydrogen atom is pulled apart to form Hydrogen ions (cations) and hydroxide ions (anions) are introduced, in which the hydrogen cations move toward the cathode and the hydroxide anions move toward the anode.
P6 Hydrogen Oxygen Gas Generation: When the hydrogen cation moves to the surface of the cathode, electrons are obtained from the cathode to generate hydrogen, 4H + + 4e = 2H 2 When the hydroxide anion moves to the anode, the electrons are released, and water and oxygen are obtained. 4OH -- 4e = 2H 2 O + O 2 .
The above six figures explain how the hydrogen and oxygen gas are generated, so how to quickly generate the hydrogen and oxygen gas? Of course, this is related to the catalytic characteristics of the electrode, the concentration and temperature of the electrolyte, and many other unknown factors. The most important aspect of the rate of hydrogen and oxygen production.
The hydrogen-oxygen bond has a chemical binding force, and the cathode of the electric field has an electric field attraction to the hydrogen atom. The two forces are in opposite directions. For example, let's use our left and right hands to pull a rubber band. The left hand represents the gravitational field of the electric field, and the right hand represents the bonding force of the hydrogen-oxygen bond. That rubber band is like the hydrogen-oxygen bond of the water molecule. 橡皮 筋拉断，这当然需要很长的时间。 If we pull slowly, we must pull to a certain degree before we can break the rubber band , which of course takes a long time. 筋是不是突然拉断了呢，这个时间是不是就缩短呢。 But if we suddenly pull on both sides, does it mean that the rubber band is suddenly pulled off, and this time is shortened?
Walker Energy was surprised when it discovered this phenomenon, and immediately researched to produce a power supply that instantly breaks the hydroxide bond.
First, let's take a look at P7 in the big picture above.
Figure P7 shows the current waveform of the traditional oxyhydrogen power supply (left) and Walker Energy's pulse increasing current waveform (right). The traditional current waveform is constant current, and its current is the same at all times. The current intensity is increasing. After increasing to the maximum current, it starts from the initial current and starts again and again. This is the pulse increasing waveform. The figure below shows the Walker resonant power supply and control system. Compared with the traditional electrolytic power supply, the efficiency is increased by 10%.
Six, gas pressure adaptive system
What is a gas pressure adaptive system? That is, the pressure of the gas output is always equal to the set pressure, regardless of whether the user increases or decreases the valve.
Let's take a look at the inconvenience caused by the lack of this voltage stabilization function in order to deepen the benefits brought by the voltage stabilization system.
We take a machine with a gas output of 1000L as an example. Now the machine with two guns automatically welds a certain kind of workpiece, which is equivalent to adjusting the gas consumption of each gun to 500L. For some reason, one of the guns is turned off, but the machine The gas production is still 1000L. Because the gas consumption is less than the gas production, it will inevitably cause the internal pressure of the machine to rise. Due to the increase in gas supply pressure, the firepower of the gun in use is bound to increase, and it is getting stronger and stronger. When the air pressure rises to 0.2Mpa, the machine automatically stops gas production. At this time, because the gun is still using gas, the pressure of the machine will become smaller and smaller, so the flame of the gun will become smaller and smaller. When the pressure is less than 1.5 At Mpa, the machine automatically produces gas, the pressure starts to rise again, and the firepower is increasing. It can be seen that if there is no voltage-stabilizing system, the flame of the gun is unstable when there are multiple guns in one machine.
实时检测沃克氢氧机的工作压力，当压力上升时，减少电解电流，当压力下降时，增加电解电流，时刻保持恒定的工作压力。 The working principle of the Walker gas adaptive voltage stabilization system is: the gas adaptive voltage stabilization system control circuit board detects the working pressure of the Walker hydrogen and oxygen machine in real time. When the pressure increases, the electrolytic current is reduced. When the pressure decreases, the electrolytic current is increased. Maintain a constant working pressure. In this way, when the customer is operating, after the valve opens a certain angle, the operator feels that the flame just meets the requirements. When another operator opens another flame gun, because the pressure output by the machine is constant, the flame of the previous operator is not Will be affected by the second operator, because the system detects that the working pressure is about to decrease, and immediately increases the electrolytic current to generate more gas to meet the needs of the second operator.
At this point, the six core technologies disclosed by Walker Energy have been introduced, and there are some technologies that are not suitable for disclosure and are not easy to introduce in detail here.
