Abstract
The utility model provides an arrange water aspirator connection structure, belongs to the drain pump field. There is the pump body in current drain pump and need uses the sealing washer to lead to the cost higher, and the pump body is fixed through calorie foot and draw -in groove locking and is leaded to the limited problem in drain pump delivery port circumference angle position, the utility model discloses a go up the pump body and lower pump body, lower pump body's upper end sets up end face of bench that the inboard is less than the outside and forms the annular groove, and the tank bottom of annular groove sets up first annular bead, go up set up on the lower terminal surface of the pump body with the corresponding second annular bead of first annular bead, first annular bead and second annular bead pass through friction welding (FW) butt fusion in an organic whole. The utility model discloses enable cost reduction, and the leakproofness is good.
Description
Technical field
The utility model belongs to draining pump field, especially relevant with a kind of draining pump pump housing attachment structure.
Background technology
Draining pump is used for drain the water away pond or the liquid in fluid reservoir, existing drawing-in type blade centrifugal drain pump pump housing bag
Upper pump casing and lower pump body are included, upper pump casing and lower pump body pass through the card base being arranged on and the mutual buckle of draw-in groove carries out axial direction and week
To being locked, because the position of card base and draw-in groove is fixed, the circumferential angle position for causing draining pump delivery port is restricted.Under
The upper end of the pump housing is set to inner side and forms annular groove less than the step end face in outside, and the lower surface of upper pump casing is provided with annular gear
Ring, upper pump casing lower surface and annular groove opening described in annular baffle ring lateral wall block, form an annular cavity close to be embedded in
Seal, due to needing to use sealing ring, causes cost to increase.
Utility model content
It is relatively costly that the purpose of this utility model aims to solve the problem that the existing draining pump pump housing need to be caused using sealing ring, and the pump housing leads to
Cross card base and draw-in groove is locked the problem for causing draining pump delivery port circumference angle position limited, there is provided one kind can be reduced into
This, makes the unrestricted draining pump pump housing attachment structure in draining pump delivery port circumference angle position.
For this purpose, the utility model is employed the following technical solutions：A kind of draining pump pump housing attachment structure, including upper pump casing is with
The pump housing, is characterized in that, the upper end of the lower pump body arranges inner side and forms annular groove, annular groove less than the step end face in outside
Bottom land first annular fin is set, second corresponding with the first annular fin is set on the lower surface of the upper pump casing
Annular ridge, first annular fin and the second annular ridge are fused to one by friction welding (FW).
Used as the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
An annular protrusion, annular protrusion are set positioned at the outside of second annular ridge on the lower surface of the upper pump casing
Use as rib, play sealing function.
The utility model can reach following beneficial effect：1st, the second ring is arranged by the annular groove bottom land in lower pump body
Shape fin, arranges the second annular ridge on the lower surface of upper pump casing, two annular ridges are fused to one, remove from by friction welding (FW)
The use of sealing ring, reduces cost, and good airproof performance；2nd, upper pump casing and lower pump body need not pass through the mutual of card base and draw-in groove
Buckle carries out axial and circumferential and is locked, and the circumferential angle position that can make draining pump delivery port is not limited.
Description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes upper pump casing 1 and lower pump body 5, the upper end setting inner side of the lower pump body 5 is low
Step end face in outside forms annular groove, and the bottom land of annular groove arranges the first ring being connected as a single entity with the lower pump body 5
Shape fin 4, arranges corresponding with the first annular fin 4 and is linked as with the upper pump casing 1 on the lower surface of the upper pump casing 1
Second annular ridge 2 of one, the annular ridge 2 of first annular fin 4 and second is fused to one, the upper pump by friction welding (FW)
An annular protrusion 3 is set positioned at the outside of second annular ridge 2 on the lower surface of body 1, annular protrusion 3 makes as rib
With playing sealing function.
Claims (2)
1. a kind of draining pump pump housing attachment structure, including upper pump casing and lower pump body, it is characterised in that：The upper end of the lower pump body sets
Put inner side and form annular groove less than the step end face in outside, the bottom land of annular groove arranges first annular fin, the upper pump
Second annular ridge corresponding with the first annular fin be set on the lower surface of body, first annular fin and second annular
Fin is fused to one by friction welding (FW).
2. a kind of draining pump pump housing attachment structure according to claim 1, it is characterised in that：The lower surface of the upper pump casing
It is upper that positioned at the outside of second annular ridge, an annular protrusion is set.
