FB/AFB stainless steel centrifugal pump

FB/AFB stainless steel centrifugal pump

Capacity: 3.36~190.8 (m³/h) 

Head: 5.2~100 (m)

Temperature: -40℃~105℃ (℃)

FB, AFB type chemical pump is a single-stage single-suction cantilever type corrosion-resistant centrifugal pump. It adopts advanced hydraulic model, novel structure and high-strength combined single and double-end mechanical seal. It has the advantages of high efficiency, energy saving, compact structure, stable performance and reliable use. .
 
This chemical pump is suitable for conveying solid particles and corrosive liquids. The temperature of the medium to be transported is -40 ° C ~ 105 ° C, and the double-face sealed cold device can transport the medium with a medium temperature of 300 ° C or less.

FB, AFB stainless steel centrifugal pump ┃ corrosion-resistant centrifugal pump Product use:
FB, AFB stainless steel centrifugal pump corrosion-resistant centrifugal pump is widely used in chemical, petroleum, metallurgy, light industry, synthetic fiber, environmental protection, food, medicine and other departments. These products adopt double-face mechanical seals, which play a great role in improving product quality, reducing running, running, dripping, leaking, preventing pollution and improving the environment. The utility model has the advantages of stable and reliable performance, good sealing performance, beautiful appearance, convenient use and maintenance, and the like.

FB, AFB stainless steel centrifugal pump ┃ corrosion-resistant centrifugal pump installation and disassembly:
1. Before installing the mechanical seal, check all components for damage. If it is damaged, it should be repaired or replaced.
 
2. Strictly check the friction end faces of the moving ring and the stationary ring, and do not allow any slight collision and scratches. Before assembly, the moving ring and static ring end face should be coated with a layer of clean engine oil.
 
3, in the assembly should pay attention to eliminate the deviation, correctly adjust the compression of the spring, so that it should not be too loose and too tight. When tightening the screws, evenly tighten them to avoid deflection and disable the seal.
 
4. Pay attention to the order of disassembly of the pump when disassembling.

FB, AFB stainless steel centrifugal pump ┃ corrosion-resistant centrifugal pump instructions:
Start:
 
1. Prepare the necessary hands and tools.
 
2. Check if the grease in the oil cup of the sealing device is injecting.
 
3. Check whether the rotation direction of the pump is correct. It is forbidden to reverse. If the steering is wrong, the impeller nut can be loosened, causing corrosion of the corrosive medium into the journal, causing the pump to fail to work, or causing the impeller nut to break out and causing an unfortunate accident. The coupling must be covered before starting the pump to ensure safe production.
 
4. When the pump installation position is lower than the liquid level (in the case of backflow), before the pump starts, the gate valve of the pipeline should be opened, and the pump liquid fills the pump. If the installation position is higher than the liquid level (vacuum condition), the pump should be pumped and vented before starting, so that the pump and the suction line are filled with liquid, and the air in the pump is drained.
 
5. After starting the motor, slowly open the discharge port gate valve to make the pump work normally, then open the valve to the required level.
 
  stop:
 
1. Close the pressure line gate valve.
 
2. Stop the motor.
 
3. Close the suction line gate valve.
 
4. When the ambient temperature is lower than the freezing point of the liquid, drain the pump memory.
 
5. If the pump is in use for a long time, the corrosive medium in the pump should be drained and rinsed with clean water. After cleaning, it should be kept safely.
 
Operation:
 
1, should always check the temperature rise of the pump and motor, mainly the bearing temperature rise, the bearing temperature is required to not exceed 73 °C.
 
2. During the operation, if noise and other abnormal sounds are found, stop the inspection immediately and operate after troubleshooting.
 
3, pay attention to the sealing device oiling cup, should maintain oil storage, and timely replenish and ensure lubrication.

Mechanical seals are used in clean, non-suspended media. Therefore, special attention should be paid to the cleaning of the pipeline for the new piping system.
