What are the hazards of high outlet pressure in a gas fan? Is there any danger to the fan when it reaches the critical pressure?
Hazard 1: Gas breaks through the water seal, resulting in massive leakage!
Hazard 2: High export pressure means high pressure in the gas collection pipe as well! In severe cases, yellow smoke will start to appear from the exhaust pipes, and the environmental protection agency will impose fines of hundreds of thousands of dollars!
It won’t have a significant impact on the fan itself; why run it at such high pressure? Is there high resistance behind the fan?
Hazard 3: High pressure at the fan outlet means the suction force in front of the fan must be low! I won’t mention the consequences! I just started learning it; I still don’t know why ? Friends, please help~!
Reply to 4# huachan2006: The resistance of the washing tower after the machine is high.
The possibility of breaking through the water seal is virtually none; the water seal is generally designed for the highest pressure. When operating under high pressure, the load on the drive mechanism is necessarily high as well, making failures more likely ； Furthermore, when the fan operates at high pressure, the axial displacement also increases, which is certainly harmful to the fan’s long-term operation.
Perform small cycles before and after the blower
The export resistance is high, which causes the operating current to increase; as a result, the device heats up； Surge may occur, noise levels increase, and the fluctuations in outlet pressure become more pronounced, leading to variations in the yield of the subsequent recovery system... Nowadays, rotary vane blowers are commonly used, as their flow rate does not change significantly; what’s important is the pressure after the blower.
It is impossible to break through the water seal; the pressure behind the machine is generally kept within a reasonable range. If this pressure remains high and the suction before initial cooling is not very high, it indicates that the resistance in the pipes of the tower behind the machine is too high, and purging is required.
Avoiding the critical speed is intended to prevent resonance
