Technical Field

The invention belongs to the field of axial flow pumps, and particularly relates to a composite axial flow pump.

Background

The axial flow pump is a pump for conveying liquid in the axial direction by the action force of the blades of the rotating impeller on the liquid, and there are vertical, horizontal, inclined and through-flow pumps.

The axial flow pump is used in underwater environment, the existing water environment is severe, and the aquatic weeds are more in impurities, so that the working environment of the axial flow pump is increasingly poor, the axial flow pump is very easy to block, an impeller is damaged, and even a motor is burnt.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to solve the problems and provides a composite axial-flow pump.

The technical scheme is as follows: the utility model provides a compound axial-flow pump, includes shell, leads impeller hub and impeller wheel hub, shell inner space from the top down is in proper order and leads impeller chamber, impeller chamber and suction chamber, lead impeller wheel hub with impeller wheel hub is connected through the pivot, impeller wheel hub runs through impeller chamber with suction chamber, impeller wheel hub's the part that is in impeller chamber is provided with the impeller, impeller wheel hub's the part that is in suction chamber is provided with the cutting blade, suction chamber both sides are provided with optical sensor respectively.

Further, the shell is made of cast iron.

Further, the impeller hub is fixed to the housing by a fixing block.

Furthermore, the impeller hub is made of aluminum alloy.

Further, the cutting pieces have 3-5 pieces.

Has the advantages that: the composite axial-flow pump provided by the invention has the advantages that the cutting blade is arranged, so that sundries which are about to be sucked into the impeller chamber are cut, the damage to a machine is reduced, in addition, the sundries can be judged in advance through the arranged optical sensor, the switch of the cutting blade is turned on, and the energy consumption is reduced.
