Except locating piece, impeller can be easily taken out, during assembly or disassembly, damaging property of impeller itself will not all be damaged,
Also it is not easy to generate abrasion to impeller, greatly improves impeller service life, also improves pump performance.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures：It is described
Locating piece is positioning ring set, and the positioning ring puts on setting axis hole, and the axis hole runs through the positioning ring set, the axis hole it is straight
Diameter is adapted with armature spindle shaft end outer diameter.In order to facilitate assembly locating piece, using positioning ring set form, when cooperating with impeller
With biggish contact area, the stability positioned to impeller is improved.Meanwhile there is more axial curved surface on locating piece, side
Just connector is arranged, and also improves the power that is critical of connector.
Peripheral pump is vertical volute pump, and when water pump is installed, mechanical seal is located at the lower section of the impeller, fix impeller with
After positioning ring set, the pump housing is installed.In use, water pump need to be turned, because impeller is set by positioning ring set fixed bit, mechanical seal
At this time in the top of impeller, impeller gravity is born on positioning ring set, the spring holding impeller position with resilience in mechanical seal
It sets constant.Impeller upper and lower surfaces are equilibrant force by the pressure of water when use, then guarantee impeller location mainly by the screen resilience of spring
It is fixed.
Transmission cooperation is formed by key between the impeller and armature spindle.Due to impeller and armature spindle loose fit, then need
It is driven by key, rotates together impeller in company with armature spindle.
In order to make the gap of impeller both ends of the surface meet the requirements, precondition is that mechanical seal setting needs to stablize, the machine
Tool is sealingly disposed in the cavity of the connector.The inner wall of connector generates axially position to mechanical seal.
One bearing is set on the armature spindle, and the bearing limits the connector, and connector is made to be fixed on armature spindle
Specific position.Under the premise of bearing plays support armature spindle, moreover it is possible to further be limited to mechanical seal, indirectly guarantee leaf
Take turns the gap of both ends of the surface.
The utility model has the advantage that：1, impeller and armature spindle clearance fit, one end face of impeller directly with machinery
Sealing, which is formed, contradicts cooperation, and locating piece then is arranged in impeller other end, impeller is made to be axially positioned on armature spindle feature position,
Accurately control gap a and the size of gap b more.2, it is loose fit between impeller and armature spindle, when disassembly, need to only tears open
Except locating piece, impeller can be easily taken out, during assembly or disassembly, damaging property of impeller itself will not all be damaged,
Also it is not easy to generate abrasion to impeller, greatly improves impeller service life, also improves pump performance；3, easy to operate, installation step
It is few.4, assembly locating piece, with biggish contact area when cooperating with impeller, is improved using positioning ring set form for convenience
To the stability of impeller positioning.Meanwhile there is more axial curved surface on locating piece, facilitate connector to be arranged, also improves connection
The power that is critical of part.
