Slurry pump import and export piping configuration and requirements July 20, 2011 Slurry pump pump import and export of pipe configuration and requirements 1, suction pipe suction pipe diameter: suction pipe diameter should be the same as or with the inlet diameter of the slurry pump Pump inlet diameter slightly larger, the principle is not only to avoid pump cavitation, but also can not make the slurry in the pipeline deposition. Inlet port gate valve: In order to facilitate the maintenance pump, suction port gate valve should be set, its diameter and suction pipe diameter the same. In the slurry pump inlet and suction pipe should be provided between the telescopic section, in order to disassemble the pump. 2, the discharge pipe diameter: discharge pipe diameter and slurry properties, settling velocity, under normal circumstances, the discharge diameter and slurry pump outlet diameter equal to or slightly larger. Exit gate valve: outlet gate valve should be the same diameter and discharge. Pressure gauge: Located on the straight pipe between the outlet of the slurry pump and the first valve. Pump pipeline configuration considerations Piping layout: diameter size to consider the system resistance, the slurry of the critical settlement velocity and other comprehensive factors. Suction tube should be as short and straight as possible. In the suction inlet of the pump, it is advisable to provide a straight pipe section of the same diameter as the inlet and its length should not be less than 3 times the inlet diameter. Suction tube flow rate is generally 1.5-3.0m / s, depending on the transport slurry settling velocity may be. When using high-position pump suction pipe should avoid the formation of cavitation, it is recommended to use the bus on the level of the adjustable tube. Regulate the flow with the valve, the control valve should be located at the pump outlet, not allowed to adjust the valve on the inlet pipe to avoid cavitation.
