What Should Be Paid Attention to When Designing the Inlet and Outlet Pipeline of the Slurry Pump?

The following are the aspects that need to be paid attention to when designing the inlet and outlet pipeline of the slurry pump:

Pipe diameter selection. The pipe diameter should be reasonably selected according to the flow rate and flow rate requirements of the slurry pump. Too small pipe diameter will lead to too high flow velocity, increasing pipe wear and resistance; too large pipe diameter will increase costs and may lead to slurry deposition in the pipe.

Pipe material. Considering the corrosion and abrasion of the slurry, choose wear-resistant and corrosion-resistant pipeline materials, such as wear-resistant steel pipes, hose lining, ceramic composite pipes, etc. When transporting highly corrosive slurry, stainless steel pipes or tetrafluoroline pipes may be required.

Reduce elbows and variable diameters. Minimize the number of elbows, tees and variable diameter tubes to reduce resistance and local wear. The elbow should be an elbow with a large radius of curvature, and the diameter-reducing pipe should be a gradient transition. If you must use an elbow, you can choose a wear-resistant elbow and increase its wall thickness.

Pipe support and fixation. Provide sufficient pipeline support to prevent the pipeline from deforming or damage due to vibrations caused by self-weight and slurry flow. The support points should be distributed reasonably to avoid excessive deflection of the pipeline. For long-distance pipelines, fixed piers and compensators should also be installed to absorb thermal expansion, contraction and vibration.

Pipe slope. The outlet pipeline should have a certain slope to facilitate the slurry to discharge itself and avoid liquid accumulation and blockage. The size of the slope is determined based on the nature of the slurry and the conveying distance. Generally speaking, the slope should not be less than 2%5%.

Sealed and connected. The connection between the pipeline and the inlet and outlet of the slurry pump should be well sealed to prevent leakage. Flange connection, welding or clamp connection can be used, and suitable sealing materials can be used. The connection area should be reinforced to withstand the tension and thrust of the pipeline.

Direct pipe section for import and export. A certain length of straight pipe sections should be installed at the inlet and outlet of the slurry pump to ensure the smooth flow of the slurry and reduce vortex and pulsation. The length of the inlet straight pipe section is usually 3 to 5 times the pipe diameter, and the length of the outlet straight pipe section is 1 to 2 times the pipe diameter.

Rinse and drain. Design a flushing interface to facilitate flushing of the pipeline during shutdown and prevent slurry from precipitating and blocking. At the same time, an emptying valve is provided at the low point of the pipeline to emptiate the slurry in the pipeline during maintenance and maintenance.
