Application fields and common problems of air electric heaters

The electric heater is an international popular high-quality long-life electric heating equipment, is mainly used for heating of the requested heated material, converted to heat energy in the process of a new type of heating device, electric heater resistance wire is made of nickel chromium alloy, high temperature above 800 degrees. It mainly has three groups of stainless steel electric heating tube together, all of them in the device on the tube plate, such as the need to change the electric heating tube, protection should be before the end of the open cover, unscrew the nut and the right opposition, decided to participate in the second - although Chavez's party votes compared to two years ago reduced votes and parliamentary seats but still got in a. The opposition coalition won the ballot and the parliamentary seat. Finally, remove the soft wire on the electric heating tube so that the electric heating tube can be pulled out for rapid replacement.

Air electric heaters are mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 degrees centigrade. It has been widely used in many research and production laboratories, such as aeronautics and Astronautics, weapons industry, chemical industry and colleges and universities. It is especially suitable for automatic temperature control and high flow high temperature combined system and accessories test. The range of air electric heater is wide: it can heat any gas and generate hot air, no water, no electricity, no burning, no explosion, no chemical corrosion, no pollution, safe and reliable, and the heating space will be heated up quickly (controllable).

It is important to know how to deal with the common leakage, heat loss and temperature drop of the heat exchanger of air electric heater.

The following are the following parts: first, let's talk about leakage. The main parts of the leakage are the seal between the plate and the plate, the two seals of the plate and the leakage slot, and the inner part of the end plate and the inner side of the pressing plate. Next, it is said that the pressure drop is large, and the pressure drop of the inlet and outlet of the medium exceeds the design requirements, even higher than the design value, which seriously affects the system's requirements for flow and temperature. In the heating system, if the pressure drop of the heat side is too large, the first side flow will be seriously insufficient, that is, the heat source is not enough, so the two side temperature can not meet the requirements.
