How to distinguish the advantages and disadvantages of radiators

The quality of radiator should be determined by the material of radiator.

1. radiator material

Common radiator materials are cast iron, steel, aluminum, copper-aluminum alloy and pure aluminum alloy. Cast iron radiator is very durable and not easy to be corroded, but its production process is not environmentally friendly and has been gradually replaced by other materials. Steel radiator has the characteristics of large water storage capacity, good heat dissipation effect, long service life and reasonable price, and is now widely used. Aluminum radiator has the advantages of rapid temperature rise, beautiful appearance, lightness and convenience, but the heating water is generally circulating water, which is more alkaline, and aluminum radiator is easy to be corroded. If it is central heating, it can't be used. At present, copper-aluminum alloy radiator is better, with good heat dissipation, corrosion resistance and good appearance, but the price is higher. The radiator made of pure aluminum alloy is more corrosion resistant, airtight, easy to clean and high in pressure resistance. At present, it is in the development stage, and it may be gradually applied more widely in the future.

Rubens radiator material:

Steel radiator: corrosion-resistant crystalline steel.

Corrosion-resistant crystalline steel, formerly known as MF 170, was imported from Russia, a big iron and steel country. Rubens invested millions of dollars to find a corrosion-resistant steel that is most suitable for manufacturing radiators. Its carbon content is only one thirtieth of ordinary low carbon steel (SPCC), and its unique crystal structure makes it 20 times more corrosion resistant than ordinary low carbon steel, even equivalent to copper, but its price is only one tenth of that of copper, which is the highest.

Copper-aluminum composite radiator: cold-rolled stretched copper tube+aluminum-magnesium alloy

Rubens copper-aluminum composite radiator adopts 99.99% purity TP5 electrolytic copper tube, which has good thermal conductivity, high efficiency and energy saving, and never corrodes. It is the most durable radiator with a service life of more than 70 years. It is made of 6063 aviation grade aluminum with high hardness and fine and uniform surface, which is more suitable for the adhesion of plastic powder and has the characteristics of light weight and good thermal conductivity.

2. Painting effect

The radiator is painted well, which can make it look good and last longer. At present, the better spray paint is imported plastic powder for radiator. The process is electrostatic spraying, which can keep smooth and bright for a long time, durable and easy to clean. A poorly painted radiator has a rough surface, which is not easy to clean and easy to fall off, and exposed metal is easy to rust. Pay attention to the painting effect of the surface when choosing.

Rubens radiator spraying technology;

The radiator runs at high temperature in the heating season, which may lead to surface fading and leg color. This requires spraying and powder molding of the radiator. A good radiator has a lasting and beautiful appearance, and the sprayed layer will never fall off and crack. Rubens radiator adopts the top spraying equipment in Europe and the best American Nippon epoxy powder coating in the world.

The whole spraying process of Rubens radiator is completed in the fully enclosed dust-free plastic spraying workshop. The whole assembly line is a150m-long hanging chain plastic spraying oven, with balanced heating of superconducting heat transfer oil, Ingersoll-Rand screw pump, Lowe cooling dryer, and three-stage activated carbon filter screen imported from the United States, which is the air purification level of mobile phone, ensuring that the surface of radiator is as smooth as that of mobile phone case. Swiss golden horse OptiFlex-F top spraying equipment has no dead angle caused by electrostatic shielding.

The brightness of Nippon epoxy powder coating in the United States reaches 98%, and the impact resistance of the coating is Grade I. All products have been sprayed and dried three times (once for engineering products and twice for market products). The radiator has fine particles on the surface, smooth surface, uniform spraying, good stability and pure color.

3. Welding process

The radiator is not integrated, but welded together. Good welding can make them airtight. Generally, radiators produced by large manufacturers are welded by automatic equipment, which has high efficiency, good quality, safety and stability. However, radiators produced by small factories are usually welded by hand or manipulator, which has poor precision, poor welding effect, unstable quality and easy cracking, and there are potential safety hazards. When selecting, you can choose products produced by big manufacturers, which has better pressure bearing capacity and long service life.

Welding technology of rubens radiator;

Seamless welding, thousands of experiments, no welding loss!

Rubens radiator introduces "laser automatic welding" welding technology on the basis of welding spot positioning before ultrasonic welding, which avoids the error of steel pipe butt joint, thus making the contact surface of welding area more uniform, without welding slag, and the thickness of welding part is several times that of wall pipe.

The assembly welding adopts the manipulator double gas shielded welding process (argon and carbon dioxide), one side is welded and the two sides are formed, so the welding heater has undergone thousands of destructive tests, and no joint is damaged first!

Handling details

You can also see the quality of heating from the details. Good radiator, the details should be fine, such as blocking lines, running wind, hooks and so on. The material is good, shiny and finely polished. However, the details of the radiator are poor in texture, the material is average, the workmanship is poor, and the appearance is rough. You can't choose it, which has security risks and poor bearing capacity.

Rubens radiator pressure testing technology;

Pressure test of radiator is an important step in radiator production and a link to detect radiator leakage. This step will be operated during radiator production and radiator installation. Only by handling these things well can we ensure the normal heating and safety of radiators.

In fact, the pressure test technology in radiator production is very simple, but there are many times. Block the diameter of the radiator with a compressor, then inflate it, and send the sealed and inflated radiator into the water to see if there is any air leakage or bubbling on the radiator surface. This process will be carried out once after the radiator is welded to the pipeline, once after assembly, once after acid phosphating, and finally the finished product. In this way, the pressure testing technology of the whole radiator production process is completed.

Rubens radiator ensures that the product does not leak. Each radiator group should be pressed four times before leaving the factory, and the test pressure is as high as 2 1 kg each time (the normal use pressure is 6-8 kg), so as to ensure that the radiator will not burst under any circumstances.

Rubens radiator header technology;

Increase the thickness of the film head and the accumulation of welding.

The deeper grinding part is not the steel pipe, but the head and solder joint. In view of this situation, the film head we use is about 0.3mm thicker than the steel pipe; In addition, the welding machine with relatively high power and welding wire with relatively large diameter increase the internal accumulation degree of solder joints, and to some extent avoid the problem that the polished part becomes a weak point in quality.

Rubens radiator polishing technology;

Divide each grinding into three times in different directions and angles.

Although the third grinding increases some processes and workload, it can not only ensure the grinding in place, but also not cause the grinding depth to be too large. Taking a steel radiator with a wall thickness of 1.5mm as an example, the rough grinding process can make the thickness of some substrates become 1.0mm, while the fine grinding and deep welding of Rubens steel radiator can ensure that the thinnest part of the polished substrate is not less than1.35 mm..

Pretreatment technology of Rubens radiator before spraying;

At present, there are two main pretreatment methods of radiator spraying, namely physical and mechanical method and chemical method.

At present, in the radiator industry, except for thick, heavy and large workpieces, physical and mechanical methods such as sandblasting or shot blasting are used instead of chemical treatment, most of them adopt chemical treatment.

Chemical treatment is to make chemical substances such as degreasing agent, rust remover and phosphating agent react with metal workpiece by soaking, spraying or wiping, so as to remove foreign substances on the surface of workpiece, produce suitable chemical conversion film and provide a good substrate suitable for painting.

Rubens radiator assembly technology;

At present, the production of radiators is mechanized, and only manual assistance is needed. The radiator assembly technology can only be completed by advanced assembly machines. The commonly used radiator assembly machine consists of a special welding machine and a welding machine, and the special welding machine consists of a body and an electrical part; The main body consists of a frame, a cross beam, an adjustable bracket, a positioning seat, a transmission component and a welding power head. The electricity consists of electric control cabinet, motor and proximity switch. The welding machine adopts argon arc welding treatment, which has the advantages of firm welding, high welding efficiency and stable radiator performance. Of course, different radiator styles have different laminating machines.
