Summary of the invention
The purpose of this utility model is to solve the problems referred to above of prior art existence and provide the peripheral pump of a kind of band choma impeller, change the arrangement mode of impeller both sides blade, make the blade dislocation arrangement of correspondence, the runner formed also misplaces arrangement, liquid effects can be made full use of in the power of impeller, improve the efficiency of pump, in addition, impeller and impeller port ring and the direct gap of connector choma is made to be limited between 0.1-0.3mm, greatly reduce impeller end face pressure release phenomenon, improve the efficiency of pump and lift, also self-priming performance is improved, but also avoid collision each other, friction, improve service life.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the peripheral pump of band choma impeller, including the pump housing, the connector being arranged in the pump housing, the impeller being arranged between the pump housing and connector, it is characterized in that being respectively equipped with on wheel disc two wall of described impeller the impeller port ring of evagination, it is provided with pump housing choma corresponding to impeller port ring described in side on the described pump housing, it is provided with connector choma corresponding to opposite side impeller port ring on described connector, the both sides of described wheel disc outer rim evenly distributed multiple radially radial blades respectively, the blade of described wheel disc both sides misplaces arrangement the most one to one.Changing the arrangement mode of impeller both sides blades, make the blade dislocation arrangement of correspondence, the runner of formation also misplaces arrangement, it is possible to make full use of liquid effects in the power of impeller, the raising efficiency of pump.
Improve as to the further of technique scheme and supplement, this utility model following technical measures of employing:
Being all matched in clearance between described impeller port ring and pump housing choma, between described impeller port ring and connector choma, described gap is all 0.1-0.3mm.The gap between impeller and impeller port ring and connector choma is made to be limited between 0.1-0.3mm, greatly reduce impeller end face pressure release phenomenon, improve the efficiency of pump and lift, also improve self-priming performance, but also avoid collision each other, friction, improve service life.
Specifically, gap includes gap between impeller port ring side and pump housing choma and connector choma, also includes the gap between impeller port ring outer end face and pump housing choma and connector choma inner ring surface.
As preferably, the diameter more described pump housing little 0.1-0.3mm of choma internal diameter of described impeller port ring outer.
As preferably, the diameter more described connector little 0.1-0.3mm of choma internal diameter of described impeller port ring outer.
As preferably, described wheel disc outer flushes with described blade outer.
This utility model has the advantages that the arrangement mode changing impeller both sides blade, make the blade dislocation arrangement of correspondence, the runner formed also misplaces arrangement, liquid effects can be made full use of in the power of impeller, improve the efficiency of pump, in addition, impeller and impeller port ring and the direct gap of connector choma is made to be limited between 0.1-0.3mm, greatly reduce impeller end face pressure release phenomenon, improve the efficiency of pump and lift, also improve self-priming performance, but also avoid collision each other, friction, improve service life.

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment: the peripheral pump of band choma impeller, as it is shown in figure 1, it includes the pump housing 11, the connector being arranged in the pump housing, the impeller being arranged between the pump housing and connector.The impeller port ring 2 of evagination it is respectively equipped with on 1 liang of wall of the wheel disc of described impeller, it is provided with pump housing choma 4 corresponding to impeller port ring 2 described in side on the described pump housing 11, it is provided with connector choma 5 corresponding to opposite side impeller port ring 2 on described connector, evenly distributed multiple radially radial blade 3 respectively, the both sides of described wheel disc 1 outer rim, the blade 3 of described wheel disc 1 both sides misplaces arrangement the most one to one.Changing the arrangement mode of impeller both sides blades, make the blade dislocation arrangement of correspondence, the runner of formation also misplaces arrangement, it is possible to make full use of liquid effects in the power of impeller, the raising efficiency of pump.
Furthermore, it is understood that be all matched in clearance between described impeller port ring 2 and pump housing choma 4, between described impeller port ring 2 and connector choma 5, described gap be all the size of the gap c in 0.1-0.3mm, i.e. Fig. 1 be 0.1-0.3mm.The gap between impeller and impeller port ring and connector choma is made to be limited between 0.1-0.3mm, greatly reduce impeller end face pressure release phenomenon, improve the efficiency of pump and lift, also improve self-priming performance, but also avoid collision each other, friction, improve service life.Conventional peripheral pump is difficult to control for above-mentioned gap, and gap is relatively big, causes the problems such as pressure release is serious, the efficiency of pump is low, lift is low, self-priming performance is poor.
