Aluminum Diecast Heater Heating Method
Aluminum Diecast Heater heating method
There are many types of Aluminum Diecast Heaters in the market, some of which we have not touched at all, so they can be said to be ignorant, Aluminum Diecast Heaters and ducts Aluminum Diecast Heaters belong to this category. Here to learn is the Aluminum Diecast Heater heating methods, as well as the air duct Aluminum Diecast Heater common problems.
For Aluminum Diecast Heaters, its heat is generated by the electric heating element provided in the heater, and the medium is heated by forced convection. And the media is imported through the container into the container, through the use of fluid thermodynamic principles, the Aluminum Diecast Heater work when the huge heat generated to achieve continuous heat transfer to achieve the requirements of heating process.
When the Aluminum Diecast Heater medium temperature close to the set value, the Aluminum Diecast Heater control system will be based on the output port temperature sensor signal, PID operation and automatically adjust the heater output power, so that the output port temperature to achieve the required requirements.
And when the Aluminum Diecast Heater heating element over-temperature, the heating element overheating protection device will immediately start, automatically cut off the heating power to avoid heating components burned, thereby extending the life of parts and get a better effect The
To say that the air duct Aluminum Diecast Heater common problems, that is, leakage, pressure drop, etc., the main part of the leakage of air duct Aluminum Diecast Heater between the plate and the plate between the seal, And the end plate and the inner side of the pressing plate.
The so-called pressure drop is large, that is, air duct Aluminum Diecast Heater in the medium into the export pressure drop over the design requirements, and thus seriously affect the system flow and temperature requirements. In the heating system, if the hot side pressure drop is too large, then it will lead to a serious lack of primary side flow, can not meet the requirements.
As the Aluminum Diecast Heater variety of styles, so users want to choose a suitable is not easy, at least for a commonly used Aluminum Diecast Heater have a basic understanding. Take Aluminum Diecast Heater as an example, know its structure, performance and working principle is what?
Starting from the structural layout of Aluminum Diecast Heater began to analyze the device will be more than one heating pipe welded to the flange, most of the use of argon arc, of course, can also use the form of fastening device, in each electric heating pipe by fasteners , In order to achieve centralized heating.
At the same time, Aluminum Diecast Heater fastener seal with a scientific process, a single replacement is extremely convenient, greatly save after the maintenance costs. And the overall structure will become more compact; it is because the Aluminum Diecast Heater as a whole short and dense, so good stability, no need to install bracket.
Second, the performance of Aluminum Diecast Heater, compared to other Aluminum Diecast Heater, its surface power, so that the surface heating air heating 2 to 4 times, by virtue of this, the device is mainly used for open, closed Type solution tank and circulation system.
Aluminum Diecast Heater using U-shaped tubular heating element, and according to the heating of different media design specifications, according to the power configuration requirements assembled on the flange cover, insert the need to heat the material. When the heat element works, the amount of heat emitted to the heated medium to the media temperature, to achieve the required process requirements.
When the medium temperature reaches the set value of the process requirements, the Aluminum Diecast Heater control system according to the temperature sensor signal, after the PID operation to adjust the Aluminum Diecast Heater output power, the heating element of the resistive load to achieve temperature control, the media temperature uniform , To achieve the required requirements.
