Abstract
The utility model relates to an improved plastic pump impeller. A plastic hub is coated outside a metal bushing; a plurality of blades are arranged on the upper end surface of the hub; the length of one part of blades is less than that of the other part of blades; the longer blades and the shorter blades are in a staggered arrangement; and the back end of each blade is parallel to the edge of the hub. The utility model has reasonable and reliable structure. When the number of the blades is not reduced and the height of the blades is not increased, an impeller inlet has large cross section, and the performance parameters of the impeller are free from influence. Compared with the prior like plastic pump impeller, the utility model has the advantages of large inlet area and good impeller intensity.
Description
Technical field
The utility model relates to a kind of impeller of plastic pump.
Background technique
The shape of She Ji its primary blades of impeller is the same generally speaking, the inlet diameter of the degree of crook of blade, blades height, blade and outlet diameter are that the energy of the liquid carried according to this impeller is determined, and the thickness of blade is to be determined by the material of impeller and prerequisite in the course of the work intensity.The length of each blade that impeller had of existing a kind of plastic pump is consistent, because plastics intensity is relatively poor, so need the Thickness Design must be thicker generally speaking with impeller, so, the charging phenomenon of blocking just appears in inlet at impeller easily, and at present, the means of avoiding stopping up commonly used are to guarantee the import cross section with increasing blades height, so just increased the axial length of complete machine, and plastic blade increase the back intensity can reduce.
The model utility content
The purpose of this utility model is to provide a kind of improved plastic pump impeller, and this impeller can reduce impeller charging blockage problem not influencing on product performance and the assurance plastic blade intensity based.
For achieving the above object, the utility model adopts following scheme: improved plastic pump impeller, metal lining is coated with the plastics wheel hub, be fixed with some blades on the wheel hub upper-end surface, the length of part blade is less than the length of another part blade, the short blade of blade that length is long and length is staggered and arranges that the rear end of each blade is concordant with the wheel hub edge.
By such scheme as seen, because the short blade of blade that length is long and length is staggered and arranges, distance between the blade front end that two adjacent length are grown is bigger, do not reducing blade, do not increasing under the condition of blade height, the cross section of impeller inlet is big, and the performance parameter of impeller can not be affected again.
The utility model is rational in infrastructure, reliable, and it is compared with the impeller of existing similar plastic pump, has the advantages that inlet-duct area is big, blade strength is good.
Description of drawings
Fig. 1 the utility model one embodiment's structural representation;
The A-A sectional view of Fig. 2 Fig. 1.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
This improved plastic pump impeller has metal lining 4 and plastics wheel hub 3, plastics wheel hub 3 is coated on metal lining 4 outsides, be fixed with some blades 1, blade 2 on plastics wheel hub 3 upper-end surfaces, the length of part blade 1 is less than the length of another part blade 2, the blade 2 that length is long is staggered with length than short blade 1 and arranges that the rear end of each blade 1, blade 2 is concordant with wheel hub 3 edges.
As seen from Figure 2, the height unanimity of the upper-end surface of all blades 1, blade 2, as seen from Figure 1, length is the length unanimity of each short blade 1, and length is the length unanimity of each long blade 2.
Claims (2)
1, improved plastic pump impeller, metal lining (4) is coated with plastics wheel hub (3), be fixed with some blades (1,2) on plastics wheel hub (3) upper-end surface, it is characterized in that: the length of a part of blade (1) is less than the length of another part blade (2), the blade (2) that length is long is staggered with length than short blade (1) and arranges that the rear end of each blade (1,2) is concordant with plastics wheel hub (3) edge.
2, improved plastic pump impeller according to claim 1 is characterized in that: the height unanimity of the upper-end surface of all blades (1,2), and length is the length unanimity of short each blade (1), and length is the length unanimity of long each blade (2).
