Characteristics of stainless steel electric heating tube
1, small size, high power: the electric heater mainly adopts cluster tube heating elements, and the maximum power of each cluster tube heating element reaches 5000KW.
2. Fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency;
3. Wide application range and strong adaptability: it can be applied to explosion-proof or ordinary occasions, with explosion-proof grade reaching B and C and pressure resistance reaching 10Mpa. The cylinder can be installed vertically or horizontally according to the needs of users;
4. High heating temperature: the maximum working temperature of the heater can reach 850℃, which is not available in general heat exchangers;
5. Fully automatic control: through the design of heater circuit, it is convenient to realize the automatic control of outlet temperature, pressure, flow and other parameters, and can be networked with computer to realize man-machine dialogue;
6. Long service life and high reliability: the heater is made of special electric heating materials, and the designed power load is reasonable. The heater adopts multiple protections, which greatly increases the safety and service life of the heater.
Principle of stainless steel electric heating tube
High-temperature resistant resistance wires are evenly distributed in the seamless stainless steel tube, and crystalline magnesium oxide powder with good thermal conductivity and insulation performance is densely filled in the gap. This structure is not only advanced, but also has high thermal efficiency and uniform heating. When the current passes through the high-temperature resistance wire, the generated heat diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and then is transferred to the heated part or the air to achieve the purpose of heating.
Matters needing attention in the use of stainless steel electric heating tube
1. components are allowed to work under the following conditions: a. The relative humidity of air is not more than 95%, and there are no explosive and corrosive gases. B the working voltage shall not be greater than 1. 1 times of the rated value, and the casing shall be effectively grounded. C insulation resistance ≥ 1mω dielectric strength: 2KV/ 1min.
2, electric heating tube should be fixed, the effective heating area must be completely immersed in liquid or metal solid, it is forbidden to empty burning. When scale or carbon deposit is found on the surface of the pipe body, it should be removed in time before use, so as not to affect the heat dissipation and shorten the service life.
3, heating fusible metal or solid nitrate, alkali, leaching agent, paraffin, etc. The operating voltage should be reduced first, and then raised to the rated voltage after the medium melts.
4. When heating the air, the elements should be evenly arranged, so that the elements have good heat dissipation conditions and the flowing air is fully heated.
5. Safety measures should be considered when heating nitrate to prevent explosion accidents. 6. The wiring part should be placed outside the insulation layer to avoid contact with corrosive and explosive media and moisture; The lead wire should be able to withstand the temperature and thermal load of the wiring part for a long time, and excessive force should be avoided when tightening the wiring screws.
