Reasons and Solutions for the Failure to Start a Slurry Pump

Reasons and Solutions for the Failure to Start a Slurry Pump. A slurry pump is a large centrifugal pump widely used in industries such as power generation, mining, coal, metallurgy, and environmental protection. It is primarily used to transport high-temperature, abrasive, and highly concentrated slurries containing solid particles, earning it the name “slurry pump.” Consequently, slurry pumps often experience issues such as severe wear on flow components and short service life. When the equipment fails to start properly, immediate troubleshooting is necessary.

1. Check the power supply: Ensure that the power supply is normal, check the connections of the connectors, inspect the contact of the switch, and verify if any fuses have blown or if three-phase power supply is lacking.

Solution: If there are circuit breaks, poor contacts, blown fuses, or phase loss, identify the cause and perform timely repairs.

2. Inspect mechanical faults in the pump: Common causes include excessively tight packing or obstructions between the impeller and pump body.

Solution: Loosen the packing and clear the water inlet channel.

3. Check for damaged components in the pump: Rusting of the pump shaft, bearings, or leakage reduction ring; severe bending of the pump shaft, etc.

Solution: Disassemble the pump and remove any debris, rust, or corrosion; straighten the pump shaft or replace it with a new one.
