The design of a slurry pump pipeline has a significant impact on the pump's performance.
The design includes both the suction pipe and the discharge pipe.
1. Design of the suction pipe
The suction pipe design should address the following points:
To prevent air accumulation, the suction pipe should maintain a slope of 0.5%-2% towards the pump. Large gate valves should be installed horizontally.
The pipeline size should ensure an appropriate carrying velocity to prevent sand settling while avoiding excessive speed that increases losses. The flow velocity inside the suction pipe is typically between 1.5-2.5 m/s.
For high head conditions, the higher end of the velocity range should be used. The suction branch flow velocity should be smaller, with the pipe either inclined at 30°-40° or bent in the appropriate direction before connecting to the main pipe.
2. Design of the discharge pipe
The discharge pipe design should address the following points:
To eliminate air entrapment, reduce resistance, and prevent intermittent spraying, exhaust valves should be installed where air is likely to accumulate.
To prevent water hammer and surges, measures such as air chambers, pressure-regulating tanks, and slow-closing valves should be used.
Care should be taken with self-closing check valves for slurry to prevent blockages. Additionally, accident discharge and flushing ports should be included.
Proper design of the slurry pump pipeline is crucial for ensuring the pump operates normally. We can provide tailored solutions to make your production more energy-efficient and effective.
