Now its security while the electric heating tube has been continuously improve, be very careful when it is for us the safe use of electric heating tube. Now almost in the production of electric heat pipe with electric SiDou is using core grinding equipment, pipe diameter high degree of standardization, work closely with equipment assembly, has high thermal effect, fast heat dissipation. It is because of these advanced production process to make production now a lot of electric heat pipe quality more stable, improve the use safety of the equipment.
Heating for fusible metal or solid nitrate, alkali, asphalt, paraffin, etc., should be used to reduce voltage, after being medium melt, can rise to the rated voltage. For heating air components should be uniform cross arranged, make the device has good heat dissipation conditions, make the air flow can be fully heated.
If you want to fully electric heating tube heating, the condition is to make the component reaches the working state of working conditions. To guarantee the stability of the rated voltage. When the design rules and on the components of components in the voltage. And the rated power is refers to the rules and the element in the design of the shell element of input power. The calculating formula of power density: length (cm) X width (cm) X0.6 ~ 0.65 = power.
In lead to great respect, it is connected to the heating element, for components and power supply, components and elements are connected with metal conductive parts. To start is the length of the element patterns on the sum of a straight and bending of metal tubes. By the infrared and industrial electric products quality supervision and inspection center testing, the electrothermal far-infrared radiation wavelengths are mainly concentrated in 4-73% – 73% between 14 um. Heating wire for linear heating, cooling the area is small. And electrothermal film is planar heating, heat exchange area is large, by the national testing center of thermodynamic parameters, electrothermal conversion efficiency of more than 96%, and radiation efficiency reached 78%, so the same power, the same temperature, more energy saving province electricity than traditional electric heating element. For consumers, the equivalent thermal and heating effect, with the electrothermal products can reach the effect of spending money to enjoy the 2000 w, 1600 w. For the electric heating tube length of fever and fever have affected surface area. Hot metal pipe length on the surface area of the unit is cm square; The power unit and heat on the surface of unit area is W/cm square.
Safe use of electricity heat pipe for the equipment and machinery are very important! The safe use of electric heating tube not only ensures the normal operation of machinery, is also very good to ensure the production safety.
It is also need to pay special attention to. The use of electric heat pipe should be fixed position. Effective heating area must be completely immersed in liquid or solid metal, it is strictly prohibited to empty it. Found a scale or carbon tube body surface, should be timely clean again, lest absence made the cooling and shorten service life.
For electric heat pipe technology, mainly for metal pipe shell now, about how to develop more advanced electric heat pipe material is now a lot of enterprises in the research of the problem. Now the most common is the use of electric heating tube alloy heating wire as a heating element. Yancheng macros and electric machinery co., LTD. The production of electric heat pipe are the best quality of alloy heating wire as the heating element. But also lead to great are encapsulates the magnesium oxide insulating medium in tube, with a fixed heating element of the electric heating element.
Although now on the market to sell electric heat pipe are made according to CE standard, according to meet the demand of most machines use. But we should pay attention to the use of electric heating tube safety attention. Generally for electric heat pipe element, its working environment should be air relative humidity is not more than 95%, explosive and corrosive gas. For the work voltage should be not greater than 1.1 times that of the rating, shell should be effectively grounded. Insulation resistance 1 m or more Ω dielectric strength: 2 kv / 1 min.
