Due to its superiority, finned tubes are more and more widely used. But there is another factor that restricts the development of finned tubes is its production cost.(Finned Tubes Product)
There are various factors affecting its production cost, but on the one hand, as long as its production efficiency is improved, its corresponding cost will naturally decrease.
Finned tube is a kind of electron tube, and the electron tube is a voltage amplifying element with high output impedance.
Finned tube and contact welding is a welding process of current heating, which requires a power supply with low input impedance. Therefore, the impedances of the two do not match, and it is difficult to output more electric power.
Only by changing the ratio of the tank circuit and adjusting the relative position of the contacts properly can the output be obtained.
Finned tubes must provide a basic power consumption to work, so reducing the standby time will save power, thereby reducing production costs.
The actual standby time in the finned tube production process is more than 50%. The selection of high-performance equipment will greatly reduce the standby time, resulting in higher efficiency and lower cost.
For the same strip steel, the probability of broken strip is related to the welded structure. When the finned tube jumps, it is also cushioned by the spring.
The elastic potential energy is proportional to the square of the displacement. When the displacement changes by 5 mm, the change of the upsetting energy is 25 times. Therefore, it is easy to break the strip steel and make the The pinch rollers are more susceptible to damage.
There is no spring in the pneumatic structure, and the upsetting force is mainly realized by the pressure of the gas. When the finned tube jumps, it is buffered by the air pressure.
When the displacement changes by 5 mm, since the length of the cylinder is 125 mm, the change only four percent. It can be said that for a constant pressure gas distribution system, the energy change caused by this change is very small, thereby reducing the probability of broken belts.
