1. Working principle:
When the original motivation to drive the impeller rotation, the role of the liquid is both centrifugal force and axial thrust, centrifugal pump and axial flow pump comprehensive, liquid to flow out of the impeller. So it is a kind of pump between the centrifugal pump and axial flow pump. Mixed flow pump than the speed higher than the centrifugal pump, lower than the axial flow pump, generally between 300-500. Its head is higher than the axial flow pump, but the flow rate is smaller than the axial flow pump, larger than the centrifugal pump. Seal packing seal or mechanical seal. Material is corrosion-resistant material.
2. Application scope:
Used for conveying clean and contaminated media, chemically neutral or aggressive media. Forced circulation, seawater aquaculture, urban gas engineering, water treatment system in chemical industry process.
3. Design features:
Mixed flow pump is to open a "pulling" type structure of the pump, check and disassembling the impeller and shaft seal, no and the pump body is connected with the pipeline. The pump shaft is equipped with precision machining, with thin oil lubrication bearing, shaft sleeve is arranged in the stuffing box cover. Oil bearing box, a constant level oiler to control. Pump body of the foot, can withstand any load from the pipeline, and the direct transmission to the foundation. In this way, the rotor will not be subjected to load due to the pump bending, so as to ensure the best use of the bearing life. Due to the larger flow area, thereby reducing the blocking. The direction of rotation of the pump, from the driver side to see, for the clockwise direction. Motor or internal combustion engine driven by power. The pump device can be equipped with a complete bleeding device, which is beneficial to the exhaust of the suction pipe.
