Question details (Performance):1. High temperature of motor, fast temperature rise.2. Overload, high outlet pressure and frequent safety valve open often.3. The vibration is intensified, the side vibration of the fan motor coupling is large, and the fan body never vibrates to vibration.4. No obvious vibration was found in no-load test of fan motor. Answer: Fault reason:Fan bearing vibration is common fault in the operation, the vibration of the fan will cause damage of bearing and blade, bolt looseness, chassis and wind damage, fan vibration rises abruptly in the operation. this is because when the gas enter impeller and the rotating blade working face has certain angle, according to the principle of fluid mechanics, gas from non-working face must be a spiral blade, so the dust particles in the gas will slowly sedimentation due to vortex. Airfoil blades are very easy to accumulate dust. When the accumulated ash reaches a certain weight, a part of the large amount of accumulated ash wi
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
Using artificially softened water in the heating circuit with your boiler can potentially cause issues and is not recommended.
Artificially softened water contains high levels of sodium ions, which can cause corrosion of the boiler and other components in the heating system. This corrosion can damage the boiler and other components, leading to leaks and reduced efficiency.
In addition, artificially softened water can cause problems with water pressure and flow rate, which can i...
If the electric current of the circulating pump in a thermal oil heater is lower than the normal value, it may indicate a problem with the pump or the system. Here are some potential causes and solutions:
1. Low fluid level: If the thermal oil level is low, the pump may not be able to circulate the oil properly, leading to lower current readings. Check the fluid level and add more oil if necessary.
2. Clogged filter: A clogged filter can restrict the flow of thermal oil, causing the pump to wo...
A biomass-fired boiler furnace that has multiple issues such as wall cracks, deformation, coking, and tilt, loose bricks, tube wall blockage, burned-out rock wool sealing, and combustion chamber wall damage requires immediate attention to prevent further damage and potential safety hazards.
Firstly, it is recommended to shut down the boiler immediately to prevent any further damage and ensure the safety of the surrounding area. The boiler should not be restarted until all necessary repa...
The horizontal hot water boiler burner refers to the burner used in the horizontal hot water boiler, which is the most important equipment in the auxiliary equipment of the horizontal hot water boiler.
The function of the burner is to send the fuel and air into the furnace constantly, organize the air flow of pulverized coal reasonably and mix them well for rapid and stable ignition and combustion.
