The cooling water tank leaks. If water leaks, the surface color of the quenched product will be blue-gray, and there will be peeling on the surface in severe cases. The reason is that the cooling water tank of the mesh belt under the quenching furnace leaks water into the inner cavity of the mesh belt, and the water is gasified and then goes upward.

Most of the boilers needed by industrial and mining enterprises in production are steam boilers. Steam is mostly used in production where a certain temperature of heat is required to meet the requirements of the production process, such as textile printing and dyeing, food sugar, rubber paper, petrochemical and other industries. Therefore, it is necessary to determine the saturated steam parameters of the boiler in accordance with the requirements of the production process. The advantage of saturated steam is that it can ensure a constant temperature required for production.HD3016S HIGH SPEED CNC DRILLING MACHINE Generally, the pressure of the boiler is always higher than the saturated steam pressure required for production, the reason is to overcome the pressure loss in the pipeline or pipe network. At present, in many cases, the boiler nameplate pressure is much greater than the pressure required for production. For example, many users have purchased a 13-pressure boiler, but actually only use the operating pressure of 5 gauge or 6 gauge. Running at such a low pressure has adverse effects on steam quality. Because the pressure decreases, the specific volume of the steam increases, and the flow rate at the outlet increases greatly, so that the phenomenon of steam carrying water increases. Generally, the pressure required for actual production plus the pressure drop required to overcome all pipeline resistance plus 25% to 30% of the pressure margin is enough.HD2525-1 CNC SINGLE- SPINDLE GANTRY MOVABLE HIGH-SPEED The head of the feedwater pump is matched with the nameplate of the boiler. The actual operating pressure of the boiler is too low, and the power consumption of the feedwater pump is obviously a huge waste.Sintered NdFeB Vacuum Heat Treatment Process The boiler steam parameters used in small power plants can be configured according to the parameters required by the steam turbine. Most of them use superheated steam at 25 gauge atmospheric pressure.
