Product Details

FSB type fluoroplastic alloy pump | fluoroplastic alloy centrifugal pump-Introduction
Fluoroplastic alloy is a corrosion-resistant material in today's world. Our unit uses this material to produce FSB and FSB-D series fluoroplastic alloy centrifugal pumps, which have strong corrosion resistance, high mechanical strength, no aging, no toxin decomposition, and can transport any concentration of acid, alkali solution, oxidant and other corrosive media. Therefore, they are widely used in industries such as chemical, petroleum, pharmaceutical, pesticide, smelting, dyeing, papermaking, electroplating, and food.

FSB type fluoroplastic alloy pump | fluoroplastic alloy centrifugal pump-Product Overview:
The FSB fluoroplastic alloy pump is designed according to international standards. The pump body is made of a metal shell lined with perfluoroethylene propylene (F46). The pump cover, impeller, and shaft sleeve are all covered with metal inserts and integrally sintered with fluoroplastic. The shaft seal adopts an external corrugated pipe mechanical seal. The static ring is made of 99% alumina ceramic or silicon nitride, and the dynamic ring is made of PTFE filling material, which is corrosion-resistant and wear-resistant. It is suitable for transporting any concentration of sulfuric acid, hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, reducing agent and other harsh corrosive media under harsh conditions. It is currently one of the world's strong corrosion-resistant equipment. It has the advantages of compact and reasonable structure, strong corrosion resistance, tight and reliable sealing performance, stable operation, low noise, high mechanical strength, no aging, no toxin decomposition, easy maintenance, smooth flow channel, high efficiency, and energy conservation. Fluoroplastic alloy pumps are widely used in industries such as chemical, acid, alkali, smelting, rare earth, pesticide, dye, pharmaceutical, papermaking, electroplating, electrolysis, acid washing, radio, chemical foil, scientific research institutions, and national defense industry to prevent running, emitting, dripping, and leaking.

All of our products are designed and optimized using computers. Our company has strong technical strength, rich production experience, and comprehensive testing methods to ensure stable and reliable product quality. Characteristics of Fluoroplastic Alloy Centrifugal Pump Products
The FSB type fluoroplastic alloy pump consists of a pump body, impeller, cover, seal, bracket, pump shaft, side shaft, suspension bolt, nut, and base plate.
1. Pump body: One steel flange ring is embedded in the connecting parts on both sides, and one molded plastic synthetic gold is made.
2. A stainless steel (1Cr18Ni9Ti) molded plastic alloy is embedded on the right side of the cover.
3. Impeller: The shaft connection method is adopted, and the metal shaft is made of steel precision machined and wrapped with plastic synthetic gold mold, which firmly integrates the impeller and the metal shaft, ensuring that the shaft root and the rear of the impeller bear the torque force during rotation. In this way, the wetted part of the medium is made of plastic alloy.
4. Mechanical seal: Adopting WB2 and ST adjustable end face sealing technology without cooling water, made of materials such as silicon carbide, high-purity alumina ceramics, filled PTFE, graphite, etc.

Usage and precautions

Installation and precautions

Before installation, the pump and motor should be inspected to ensure that all parts are intact and free of debris inside the pump.

2. Place the pump in a horizontal position, connect the inlet and outlet pipes, and connect the power supply Then manually rotate the coupling Check for any signs of collision or rubbing If the rotation is easy and uniform, the installation is complete.

3. Plastic alloy pumps have lower rigidity than metals, so the weight of the pipeline cannot be directly pressed on the pump body. Additional brackets should be added to support the inlet and outlet pipelines Pumps with high head should also be equipped with check valves at the outlet To prevent water hammer damage caused by sudden shutdown.

4. All joints must be kept sealed To prevent air leakage and liquid from affecting the working performance of the pump.

5. If there is any movement or abnormal sound during operation Immediately stop the vehicle to investigate the reason Therefore, work can only be carried out after elimination.

Start and Stop

1. Fill the water pump with sufficient liquid (drainage).

2. Check if the oil level in the bracket oil chamber is within the specified range.

3. Check the direction of motor operation Check the rotation mark of the pump.

4. Close the outlet valve and pressure gauge plug.

5. Start the motor Open the pressure gauge plug Slowly open the outlet valve, when the pressure is high

When making an important stop, first close the water outlet valve and then cut off the power supply.

When the pointer of the force gauge points to the desired position Stop adjusting the size of the outlet valve.

Dismantling and installation

Disassembly of pump

1. The pump and motor are connected using a claw type coupling. When disassembling, first loosen the four connecting bolts between the bracket and the base Disconnect the pump from the motor.

2. Loosen the connecting bolts of the pump body back cover Gently tap the pump body with a wooden handle to detach it.

3. Loosen the suspension bolts connecting the impeller shaft and pump shaft with a Mohs taper in the coupling.

4. Release the mechanical seal! Without fixing the screws, lightly tap the central suspension bolt of the coupling with a wooden hammer, loosen the Mohs taper of the impeller shaft and pump shaft, and then pull out the impeller, rear cover, and sealing ring Loosen the cover screw on the back cover Remove the static damage.

5. Loosen the left and right cover screws of the pump shaft Remove the pump shaft, bearings, and clean the bracket oil chamber.

assemble

Install the sealing components such as the dynamic ring, static ring, rear cover, gland, impeller, pump body, etc. in the reverse order of disassembly and tighten the bolts.

Malfunctions and troubleshooting

Fault

Reason

solution

Unable to produce liquid

1. There is air inside the suction pipe Blockage at the entrance

2. Suck up too high

3. Require the head to be greater than the pump head

4. The discharge pipe is too thin Excessive pipeline loss

5. Reverse

1. Clean the pipeline and exhaust the air completely

2. Reduce the installation height of the pump

3. Replace the pump with a high head

4. Replace the output pipe with a larger diameter and pump port

5. Change direction

Insufficient traffic

1. Damaged impeller

2. Seal damaged

3. Insufficient quantity

4. The imported pipe is too thin

5. There are too many bends in the outlet pipe, resulting in excessive resistance

1. Replace the impeller with a new one

2. Replace the sealing component

3. Increase RPM

4. Reinstall the pipeline according to regulations

5. Reasonably rearrange the pipeline

Insufficient head

1. The conveying medium contains gas or the viscosity of the medium is too high

2. Damage to impeller and blades

3. Insufficient RPM

1. Reduce medium viscosity or increase injection pressure

2. Replace the impeller

3. Increase RPM

Shaft end leakage

1. The mechanical seal clamp ring is too loose

2. The gap between the transition dimensions of the shaft end snap ring is too large

1. Tighten and clamp two hexagonal screws

2. Disassemble the pump and wrap the shaft and stopper around the F4 raw material film several times Tight fit Tighten the bolt

Serious seal leakage

1. Improper selection of sealing component materials

2. Severe wear and tear

3. Uneven kissing between moving and stationary rings

4. Excessive friction causes the static ring to shatter

1. Explain the condition of the medium to the supply pump in series and provide appropriate dynamic and static rings

2. Replace worn parts Adjust the spring pressure to reduce wear and tear

3. Re adjust the position of the sealing assembly's loose clamp ring bolt

4. Disassemble the entire pump Replace the static ring and install the sealing assembly according to the requirements. The perpendicularity error between the assembly and the shaft should be less than 0.10

There is noise or pump vibration inside the pump

1. The pump shaft and motor shaft are not concentric

2. Cavitation occurs when the flow exceeds the usage range

3. Pump generates cavitation

4. Motor and bearing wear

1. Correct the center of the pump shaft

2. Choose the appropriate pump type Operate according to the pump's usage range

3. Reduce the temperature of the medium or increase the injection pressure

4. Clean or replace bearings
