Description

Technical Field

[0001] The utility model relates to the field of pipeline pumps, in particular to a pipeline pump connecting seat. Background Art

[0002] Pipeline pump is a type of single-suction single-stage or multi-stage centrifugal pump, which is a vertical structure. Because its inlet and outlet are on the same straight line and have the same inlet and outlet diameters, it resembles a section of pipeline and can be installed at any position of the pipeline, so it is named pipeline pump (also known as booster pump). Structural features: It is a single-suction single-stage centrifugal pump, with the inlet and outlet being the same and on the same straight line, perpendicular to the axis centerline, and a vertical pump.

[0003] A connecting seat is installed inside the pipeline pump. The connecting seat can prevent the water inside one end of the pipeline pump from entering the motor fixed at the other end, and can also support the rotating shaft to reduce the burden on the rotating shaft. The common connecting seats on the market have a gap between the rotating shaft and the connecting seat during use. When the water flow rate is high, water will squeeze into the motor installed on the right side of the connecting seat through the gap, which brings inconvenience to the use of the pipeline pump and reduces the service life of the device.
