Pipe pumps are centrifugal pumps used to transport liquids in pipeline systems. The core features are compact structure and easy installation, and they can be directly connected in series in the pipeline for use.
Core Introduction
Application Scenarios: Widely used in building water supply and drainage, heating and ventilation, industrial circulating water, urban water supply and drainage, etc., suitable for transporting clear water, hot water, or liquids with physical and chemical properties similar to clear water.
Structural Features: The pump body and motor are coaxial, with a small volume, light weight, and the same caliber for the inlet and outlet ports on the same center line. There is no need to change the pipeline direction during installation.
Working Principle: It relies on the centrifugal force generated by the high-speed rotation of the impeller to suck the liquid from the suction end, and after being pressurized by the impeller, it is transported to the pipeline system from the discharge end.
Key Parameters
Flow rate (Q): The volume of liquid transported per unit time, the commonly used units are m3/h, L/s, and it is one of the core bases for selecting the pump type.
Head (H): The energy obtained by unit weight of liquid after passing through the pump, the commonly used unit is m, and it needs to match the resistance loss and the required lifting height of the pipeline system.
Speed (n): The rotation speed of the motor driving the impeller, the commonly used unit is r/min, which directly affects the flow rate and head of the pump.
Power: Including shaft power (the power required by the pump shaft) and motor power (the rated power of the matching motor), the commonly used unit is kW, and it needs to meet the transportation requirements and leave room for redundancy.
Rated pressure: The working pressure that the pump can withstand, it needs to match the design pressure of the pipeline system to avoid overpressure operation.
Medium temperature: The temperature range of the applicable liquid, the conventional pipeline pump is suitable for - 20℃~120℃, and the high-temperature type can adapt to higher temperature media.
Inlet and outlet caliber: The caliber size connected to the pipeline, the commonly used unit is mm (such as DN50, DN100), and it needs to be consistent with the pipeline specification.
