The proportion of explosion-proof electric heater in the machinery industry is relatively large. When the explosion-proof electric heater technicians of China electric heater network install the pump of the explosion-proof electric heater, they find that when the explosion-proof electric heater works in a certain pipeline, the actual working state of the explosion-proof electric heater depends not only on the performance curve of the electric heater itself, but also on the relevant explosion-proof electric heater of China electric heater network In the research work of electric heater, heat exchanger technicians found that the working voltage of explosion-proof electric heater also depends on the characteristics of the whole pipeline of explosion-proof electric heater.

During the experiment of explosion-proof electric heater, the technicians of China electric heater network found that in the device system of explosion-proof electric heater, the working characteristics of different pumps of explosion-proof electric heater are different. In the study of the working characteristics of the constant speed pump and the variable speed pump of the explosion-proof electric heater, the technical personnel of the explosion-proof electric heater in China's electric heater network found that there are great differences, so that the flow of the explosion-proof electric heater, the head of the explosion-proof electric heater, and the heating efficiency of the internal high temperature voltage of the explosion-proof electric heater are different, which also has an impact on the heating effect of the electric heater.
