Description
Technical field：
The present invention relates to a kind of anti-clogging axial-flow pump, belong to mechanical equipment technical field.
Background technology：
Axial-flow pump impeller is equipped with 2~7 blades, in tubular pump case internal rotation.Fixed guide vane is housed on the pump case of upper impeller,
To eliminate the rotary motion of liquid, it is allowed to be changed into being axially moved, and the kinetic energy of rotary motion is changed into pressure energy.Axial-flow pump
Stage type is made in typically single stage type, minority.Range of flow is very big, be 180~360 ten thousand steres/when；Lift is typically at 20 meters
Below.Axial-flow pump is generally vertical, and impeller is immersed under water, also there is horizontal or inclined axial flow.The impeller of small axial flow pump
, it is necessary to be started with vacuum pump discharges diversion when installation site is higher by the water surface.The blade of axial-flow pump is divided to fixed and adjustable two kinds
Structure.The applying working condition of Large Axial Flow Pump often needs to make larger variation in operation, adjusts the established angle of blade and pump can be made to exist
High efficient area operation is maintained under different operating modes.The blade angle of pony pump is usually fixed.Axial-flow pump is primarily adapted for use in
The occasion of low lift, big flow, such as irrigation, water drainage, dock draining, the water level regulation of canal ship lock, or follow as power plant is large-scale
Ring water pump.The higher axial-flow pump of lift（Twin-stage is made if necessary）It is available for the hydraulic jet propulsion of shallow draft ship to be used.
During axial-flow pump is applied during the water drainage or claps sewage, due to having some floating objects in sewage,
Easily it is stuck in during water suction between impeller or stator, causes impeller operation not smooth, seriously can then cause pump shaft to be broken, be
Solve the above problems, prior art typically sets filter screen using the position of the water-inlet horn mouth in axial-flow pump, but is absorbing water
During, the floating object of some lightweights such as leaf is readily adsorbed on filter screen, causes filter net jam, causes axial-flow pump water suction not
The situation of smooth even idle running occurs.
The content of the invention：
The purpose of the present invention is to provide a kind of anti-clogging axial-flow pump for above-mentioned problem, effectively lightweight can be avoided to float
The clogging filter screen of thing or clogging impeller, it is stable and reliable in work.
Above-mentioned purpose is realized by following technical scheme：
