Product details
Introduction:The FYL type high-efficiency energy-saving long axis submersible pump is a vertical centrifugal pump, with high efficiency, energy saving, and stability being its biggest advantage. It is mainly used for transporting neutral or corrosive, clean, or liquids containing small amounts of solid particles.
The commonly used components for FYL long shaft submersible pumps in contact with the medium include CS, 0Cr18Ni9, 1Cr18Ni9, 0Cr18Ni9Ti, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, 40Cr, Monel, 1Cr18Ni12Mo2Ti, Ti (titanium), 00Cr17Ni12Mo2Ti, Hastelloy B alloy, 0Cr25Ni20, F5 series alloys, 20 alloy steel, Materials such as 0Cr25Ni6Mo3Cu2Mn2Si can be selected by users according to actual working conditions.
Application:Especially suitable for industries such as petroleum, chemical, power, metallurgy, pharmaceuticals, papermaking, and environmental protection.
Performance range:Flow rate Q 3.2~1500m3/h
Head H 5~80m
Export diameter DN 20~300mm
Design pressure 1.6MPa
Design temperature -20~180 ℃
Explanation of pump model meaning:
Structural features:Choose the best hydraulic design software in China to design hydraulic models, which have the advantages of high efficiency and energy saving; The whole machine operates with low vibration, low noise, and long service life; The self rotating component can be adjusted axially and adopts multi-point support, ensuring reliable and balanced pump operation; The pump adopts a long axis structure, with an insertion depth of up to 10 meters. The shaft connection structure is safe, reliable, and easy to disassemble; Sliding bearings can be lubricated with external cooling or self cooling; When the pump is started, the impeller is immersed in the medium, making it easy to start and there is no problem of exhaust or suction; The export flange is divided into semi movable flanges for easy connection; When viewed from the motor towards the pump end, the pump rotates counterclockwise.

Troubleshooting methods and ordering instructions
|
fault |
reason |
Elimination methods |
|
Unable to produce liquid |
1. Motor rotation is incorrect 2. Liquid not submerged in the centerline of the impeller |
1. Change direction 2. Adjust the immersion height |
|
Insufficient traffic |
1. Severe corrosion of impeller 2. Insufficient rotational speed 3. The clearance between the impeller and the pump cover is too large 4. Partial blockage of suction or pressure outlet |
1. Replace the impeller 2. Increase RPM 3. Adjust the gap again 4. Eliminate the silted area |
|
Insufficient head |
1. The conveyed liquid contains gas 2. The impeller is severely corroded 3. Insufficient rotational speed |
1. Reduce liquid temperature and eliminate gas 2. Replace the impeller 3. Increase RPM |
|
Power overload |
1. Traffic exceeds the usage range 2. Excessive medium density 3. Generate mechanical friction 4. The packing is pressed too tightly |
1. Operate according to the pump's usage range 2. Replace the high-power motor 3. Check the friction area, adjust or replace worn parts 4. Adjust the packing gland |
|
Bearing overheating |
1. The pump shaft and motor shaft are not concentric 2. Oil shortage or deterioration in the bearing box |
1. Adjust Concentricity 2. Refueling or changing oil |
|
Noise or vibration |
1. The pump shaft and motor shaft are not concentric 2. Transporting liquids containing gases 3. Unbalanced rotor 4. The nut is loose 5. Excessive wear of water bearing and journal |
1. Adjust Concentricity 2. Reduce liquid temperature and eliminate gas 3. Replace parts 4. Tighten the nuts of each part 5. Replace the water bearing and restore the journal |
