Common Faults and Troubleshooting of SB Sand Pumps

S/N

Fault

Cause

Troubleshooting

1

Excessive shaft power

1. Friction between   impeller and pump base end face/guard board/auxiliary impeller

2. Pump operates under   a condition where head is much lower than that of the design point.

3. Excessively tight packing   gland

1. Adjust clearance   between impeller and pump base end face to eliminate friction.

2. Check whether the   service machine meets requirements; make opening of the drainage valve   smaller, to make pump operates at the design point.

3. Loose the gland.

2

Reduced head and flow

1. Large particles   block suction pipe and impeller flow passage

2. Lower Speed of pump

3. Worn impeller

4. Excessive clearance   between impeller and pump base end face, and increased leakage

5. Too small opening   of inlet valve

1. Eliminate tamper.

2. Make pump operates   at the rated speed.

3. Replace impeller.

4.Adjust clearance   between impeller and pump base end face.

5. Open inlet valve   wider.

3

Bearing overheat

1. Too much or little   lubricant

2. Foreign substances   in oil

3. Worn bearing

1. Keep oil surface at   position as specified by the oil level gauge.

2. Replace lubricant.

3. Replace bearing.

4

Vibration and abnormal noise produced during pump   operation

1.Unbalanced wearing of impeller

2. Worn bearing

3. Loose connection

4. Cavitation of pump

1. Replace impeller.

2. Replace bearing.

3. Tighten all loose   parts.

4. Improve suction   condition, to prevent air into pump.

5

Serious leakage

1. Seriously worn   shaft sleeve.

2. Ineffective   mechanical seal

3. Inconsistent   inclined mouth of packing ring

1. Replace shaft   sleeve.

2. Replace mechanical   seal.

3. Fill packing ring   again as per requirements.
