There are many kinds of fire engines, and vortex fire engines are one of the most powerful fire-fighting equipment. They have unique advantages in extinguishing the ventilation and cooling of wallpapers and oil and gas fires. Now in Asia, many countries have The production of R&D and sales of vortex fire engines is different because each company's design philosophy is very different. Therefore, the structure of each vortex firefighting device has different characteristics.
1. When a vortex fire engine arrives at a fire site to extinguish a fire, the vortex extinguishing system will fire the extinguishing agent in a horizontal direction with a high degree of strength, high flow, and a large distance. And the ability to penetrate the center of the flame is relatively strong, which can significantly raise the efficiency of fire extinguishing, and reduce the environmental pollution and water-logging disasters. The effect of extinguishing the fire can be achieved in a short time.
2. The cooling performance of turret fire engines is mainly reflected in the larger size of the water guns and the high flow rate. After the fire extinguishing agent is sprayed, it will show a horn-shaped diffusion. After field-related tests, it is found that the maximum diffusion arc of the vortex fire truck can reach a height of 50 m or more, and it can perform a packaged full-range cooling of the parts to be cooled. This is especially true for the protection of oil pipes caused by fires in petrochemical industry.
3, vortex firefighting fire trucks can implement positive pressure ventilation for the county town, can immediately send smoke, effectively improve the visibility of the fire scene, greatly reducing the possibility of flash fire, help firefighters organized attacks and cover withdrawal. After the fire has been extinguished, or if a large-scale petrochemical company has leaked, a positive pressure air supply can be immediately implemented, and cooling, cooling and diluting harmful gases can be efficiently and effectively performed to protect the affected people and firefighters.
4. It can effectively use the huge kinetic energy of vortex fire engines and always spray from the side of the fire to prevent the fire from crossing the fired area, preventing the fire from spreading, protecting the surrounding buildings and avoiding the fire again. Caused more damage. (Text / Sun Ni)
There are three kinds of planer blades in the market, steel planer or tungsten carbide tipped(TCT) planer or solid carbide planer blade. Specialized in tungsten carbide material, Zhengtong supplies high standard carbide( or tct) wood planers with features of toughness, hardness, wear resistance and shock resistance.
We manufacture tungsten carbide TCT planer blades to fit all portable electric planers and wooodworking planing machines.These blades are ground to high surface finish and perfectly parallel sets to minimize noise and ensure lower maintenance and longer equipment life. They are suitable for woodworking planer, thicknesser, double-side planer on the processing of wood, plywood, multilayer board, plastic board.
