we provide advice of submersible pump installation,submersible pump working,submersible pump troubleshooting,submersible pump stopped and other pump technology articles.
Suction diameter: suction diameter should be slurry pump inlet diameter equal to or with a pump inlet diameter ratio is slightly larger, the principle is not only avoid pump cavitation, and cannot make slurry formation of deposits in the pipeline.
Inlet valve: to facilitate the maintenance of pumps, should be provided with a suction port gate valve, the diameter of the same diameter and suction pipe diameter. In the suction pump and the suction pipe should be set between the expansion joints, so that pump assembly.
Discharge diameter: discharge pipe diameter and slurry properties, sedimentation velocity, under normal circumstances, discharge diameter and slurry pump outlet diameter equal or slightly larger.
Outlet gate valve: outlet valve should be the same as the discharge diameter.
Pressure gauge: located in the straight section between the slurry pump and the first valve on the outlet.
The comprehensive factors such as the system resistance and the critical settling velocity of slurry should be considered. Suction pipe should be as short and straight. In the suction inlet of the pump, it is best to be equipped with a section of the same inlet diameter, the length should be not less than 3 times the diameter of imports. The flow velocity in the suction pipe is generally 1.5-3.0m/s, which is determined by the sedimentation velocity of the conveying slurry.
The high pump suction pipe layout should avoid the formation of cavitation, recommend the use of bus for horizontal tube.
When adjusting the flow with the valve, the valve should be located in the pump outlet, does not allow the valve on the inlet pipeline to adjust, so as to avoid cavitation.
