Advantages and disadvantages of electricity and steam used in tire local vulcanizer

Both electric heating and steam have obvious defects.

Steam: 1) Safety is the biggest hidden danger. The barometer will explode if it fails for a long time, causing personal injury.

2) Heating with coal will also involve safety and fire prevention. In addition, sanitary reasons such as ash will also have a certain impact on the quality of tire repair.

3) It takes up human resources and must be watched.

The only advantage of steam heating is low cost.

PS: Four pressures are not enough at all. At least six pressures are required.

Electric heating: 1) uneven heat distribution, high temperature near the heating pipe, maximum temperature difference 10 degrees.

2) There are many wearing parts and consumables, and the failure rate is relatively high.

3) High cost (electricity consumption).

Its advantage is convenience and hygiene. (For steam only)

At present, the most popular and commonly used heating method is heat transfer oil, which combines all the advantages of the first two heating methods, and the electricity consumption cost is between them. Suggest this as the first choice. Don't consider those two if they are unnecessary.
