The role of magnesium powder in electric heating tubes cannot be ignored

The role of magnesium powder in electric heating tubes is often overlooked. Here, Fulan Electric Appliances tells you that irregular filling of magnesium powder can cause instability in the use of electric heating tubes. Therefore, there is a necessary connection between the filling of magnesium powder in the production process and the quality of the electric heating tube. Below, we will introduce three aspects that Fulan Electric Appliances has noticed during the production process.

1. Whether the manufacturer (magnesium powder) matches according to this ratio, there is a serious problem of excessive coarse and fine sand in the actual use inspection data.

2. During the long-distance transportation of this electric heating tube product, there will inevitably be screening of sand particles with different mesh sizes. If it is poured directly into the powder bin without remixing before use, the flow rate cannot be guaranteed;

3. During the vibration process of the filling machine, it is certain that it will cause the screening of sand particles in the powder bin. Therefore, the reason why there is a significant difference in the filling weight of the same tube during operation is due to the above three factors. Of course, the factors that affect the flow rate are not only the mesh ratio, but also the viscosity and humidity of the moisture-proof agent, which is a detail that magnesium powder factories must pay attention to in real time.

Check that the opening and closing of valves in the pipeline should be in the correct position and the status of the valves should not be changed arbitrarily; Check, record and analyze the air pressure at the inlet and outlet of the electric heater, which should meet the design requirements. If the air pressure value is found to be too low or too high, the system operating parameters should be adjusted in a timely manner, otherwise it will accelerate the damage of the electric heating tube;

Then, check whether the grounding wire of the explosion-proof electric heating tube body is intact and whether the installation is firmly connected to avoid personal electric shock accidents; Check if the bottom cooling fan and cabinet cooling fan of the SCR power regulator are running well. If they stop running, replace them with new fans immediately; Check if the air conditioning in the distribution room where the control cabinet is located is running normally, measure and record the temperature of the distribution room, and if any abnormalities are found, they should be dealt with immediately; Measure the operating temperature of the SCR power regulator thyristor. If the measured value approaches 70 ℃, measures should be taken to increase ventilation and heat dissipation to reduce the temperature. If necessary, stop the operation of the group for inspection;
