The thread section of the control screw penetrates through the connecting hole and is connected with the middle support to tightly press and fix the fluid director and the middle support, and at the moment, the fluid director and the middle support have high connecting strength, are not easy to separate and cannot influence the assembly of the water pump easily. The positioning spigot at the bottom of the diversion shell can be embedded into the middle bracket to improve the connection strength between the fluid director and the middle bracket, so that the fluid director and the middle bracket are not easy to separate and influence the assembly of the water pump. When the fluid director and the middle bracket need to be assembled, an O-shaped ring can be embedded in the O-shaped ring mounting ring groove to seal the gap between the fluid director and the middle bracket and improve the sealing property between the fluid director and the middle bracket.
Description
Technical Field
The utility model relates to a spare part for a water pump, in particular to a fluid director of the water pump.
Background
At present, chinese patent publication No. CN108757491A discloses a water pump, which includes a pump body and a motor disposed inside the pump body. The pump body includes pump cover, pump case and the pump seat that from top to bottom connects gradually. The middle part of the pump shell is provided with a middle bracket, and the bottom surface of the middle bracket is provided with a middle bracket positioning spigot. The top of the pump seat is provided with a pump seat positioning spigot. A flow guide cover is arranged in the pump body, the upper end of the flow guide cover is embedded into the middle support positioning spigot, and the lower end of the flow guide cover is embedded into the pump seat positioning spigot. A pump shaft is butted on a rotating shaft of the motor, and a plurality of impeller sets are arranged on the pump shaft.
However, when the water pump is not assembled, the air guide sleeve is only inserted into the pump base at the bottom, and at the moment, the connection strength between the air guide sleeve and the pump base is low, so that the air guide sleeve and the pump base are easy to separate, and the assembly of the water pump is influenced to a certain extent.
SUMMERY OF THE UTILITY MODEL
In view of this, an object of the present invention is to provide a fluid director for a water pump, which has the advantages of high connection strength with a pump base, difficulty in separating from the pump base, and difficulty in affecting the assembly of the water pump when the water pump is not assembled yet.
In order to solve the technical problem, the technical scheme of the utility model is as follows: a fluid director of a water pump comprises a fluid director shell, wherein a plurality of connecting lugs are arranged on the outer side wall of the fluid director shell, and each connecting lug is provided with a connecting hole; the bottom of blower inlet casing is provided with the location tang, and O type circle installation annular has been seted up to the lateral wall department of location tang. When the adjustable fluid director is used, the threaded section of the controllable screw penetrates through the connecting hole and is connected to the middle support to tightly press and fix the fluid director and the middle support. The fluid director and the middle bracket which are compressed and fixed by the screws have stronger connection strength, and the fluid director and the middle bracket are not easy to separate and influence the assembly of the water pump. The positioning spigot at the bottom of the diversion shell can be embedded into the middle bracket to further improve the connection strength between the fluid director and the middle bracket, so that the fluid director and the middle bracket are not easy to separate and the assembly of the water pump is not easy to be influenced. When the fluid director and the middle bracket need to be assembled, an O-shaped ring can be embedded in the O-shaped ring mounting ring groove to seal the gap between the fluid director and the middle bracket and improve the sealing property between the fluid director and the middle bracket.
The lateral wall department of engaging lug is seted up flutedly, and the recess communicates with the connecting hole. The side wall of the connecting lug is provided with a groove communicated with the connecting hole, so that a screw can be more conveniently placed into the connecting hole.
The connecting lugs are uniformly distributed along the circumferential direction of the diversion shell, and the connection between the fluid director and the middle bracket can be more stable by matching the connecting lugs.
The center department of blower inlet casing runs through and is provided with the shaft hole, has seted up a plurality of through-holes on the blower inlet casing, and a plurality of through-holes use the shaft hole to distribute as central circumference array. The through holes arranged on the diversion shell can reduce the material required by the production of the diversion device, and reduce the production cost of the diversion device to a certain extent. A plurality of through-holes use the shaft hole to distribute as central circumference array, so set up the influence minimum to blower inlet casing structural strength for the blower inlet casing is not fragile.
The through hole is arc-shaped, and the circle center of the through hole is superposed with the circle center of the shaft hole. The through hole is arc-shaped, so that the material required by the production of the fluid director can be reduced to the maximum extent, and the production cost of the fluid director can be reduced to a certain extent.
The top of blower inlet casing is provided with spacing tang, and sealing washer installation annular groove has been seted up to the lateral wall department of spacing tang. When the fluid director is assembled, the limiting spigot is embedded into the pump shell to limit the relative transverse movement between the fluid director and the pump shell, so that the fluid director is more convenient to install. When the fluid director is assembled, the rubber sealing ring is embedded in the sealing ring mounting ring groove and used for sealing a gap between the fluid director and a pump shell and improving the sealing property between the fluid director and the pump shell.
