The LNG compressors can be extremely large, with centrifugal impeller diameters in the range of 1300–2000 mm. A large 1750 mm diameter impeller is shown in Fig. 10.3.Internal compressor casing diameters can be up to 4000 mm for horizontally split compressors and 2600 mm for barrel designs.Inlet flows for centrifugal compressors can reach 300,000 m 3 /h.

Slurry Pumps

Cavitational wear usually disrupts the pump operation and builds up vacuum in the suction line. Uneven interfacing of parts, high spots from electric welding and worn-out surfaces contribute to the cavitation, which results in stronger vibration of the pump and wear of absolutely all parts: drive shaft, support bearings and even foundations.

6 Major Reasons Why Slurry Pumps Go Bad and What You Can Do

Cavitation damages and erodes essential pump components such as the impeller, seals and pump casing. If the problem isn't fixed, it will rapidly decrease pump performance, pump wear and costly replacement and maintenance operations. 3. Pump Is Operating Below Best Efficiency Point (BEP) The BEP depicts the pump's most efficient operation.

Pump Impellers – The Types & Their Impact | Castle Pumps

The impeller is the rotating component within the centrifugal pump design, which transfers the energy from the pump's motor to the fluid. It is made up of vanes that come off an open inlet at the centre, known as the eye, which create a centrifugal force as they …

How to reasonably design the suction pipe of centrifugal pump

3) The vibration of the pump unit exceeds the standard. 4) Premature failure of bearings and mechanical seals. 5) Premature wear and failure of other parts of the pump, such as wear rings. 6) Cavitation damage occurs to the impeller and pump casing. 7) Leakage occurs at the interface flange.
