天天乐棋牌 Application of exhaust fan fire has now widely used in various occasions, the fan is not strange, but the exhaust fan fire service life will be affected by many factors, all of this information to the specific understanding of how much, today we explain below:
1. The exhaust pipe of the casing of the fire smoke exhaust fan is reformed after the fan impeller water spraying device is reformed. The fan impeller has less sludge, most of which is washed off and flows through the drain pipe installed at the bottom of the fan housing and then flows into the water seal well. Because the pipeline is long, unreasonable, turn more.
In addition, the original design pipeline nominal diameter is only 50mm, resulting in frequent blockage of the pipeline. Once the pipeline blockage, smoke exhaust fan casing was soon filled with water, and if that is not timely, will cause severe vibration of fan, causing damage to the bearing, bearing fan base crack, the serious consequences as can be imagined.
2 、 the impeller water pumping device of the fire exhaust fan, the converter dust removal fan is responsible for the flue gas emission task of converter steelmaking. Due to various reasons.
The dust content in the flue gas entering the fan from the flue is very high, and the dust particles are contacted with the impeller of the fan. Adhering to the surface of the fan impeller, more and more, and it is difficult to achieve balance, resulting in fire exhaust fan vibration due to the imbalance of the impeller.
Because of the double task of dust removal and gas recovery, the 3 and three way blowdown pipes are installed on the air outlet pipe of the blower.
天天乐棋牌 When the gas is recovered, the three-way valve is opened, the converter flue gas flows through the three-way valve and the gas holder is realized, so the gas recovery is realized. When the gas recovery is finished, the three-way valve is closed, the flue gas flows through the three-way valve and the chimney is discharged into the atmosphere by the chimney.
