From 1 data analysis of table：
1. 14 mounting means of concatenated impeller and independent self-priming water supply chamber 17 of this programme setting, self-priming excellent,
Concatenated impeller 14 increases active force, while good self-priming effect meets land use condition, and the coordination of the two makes dress
Set with superior lift, but independent self-priming water supply chamber 17 and concatenated impeller 14 result in pump internal pressure it is excessively high, overflow pipe 3
Cleverly solves the problems, such as this, and aial flow impeller 15 plays the role of playing supercharging, very low suction to impeller 14
People's surplus just disclosure satisfy that the overload free demand of the need satisfaction of total head total head；
2. in the prior art I：The quantity that impeller is limited to the impeller mounting means of dress, to limit lift, although
The pedestal that the device is provided with self-priming water supply function disclosure satisfy that land use condition, due to the defect of the impeller to dress, cause
Lift is poor；And to result in pump internal pressure excessively high for the pedestal of independent self-priming water supply function, and pump that internal pressure is excessively high to lead to liquid
Body penetrates into the internal structure of motor damage motor, although the water outlet of device setting pumps the excessively high problem of internal pressure to alleviate,
It is the problem of but bringing leakage；Especially the device does not have the overload free ability of total head；
3. in the prior art II：I pair of impeller mounting means filled comes concatenated impeller mounting means compared with the existing technology
Say that there is more excellent lift, but the impeller of the device water pump is arranged to entire body structure with water inlet, cannot generate very
Good pressure difference, therefore self-priming effect is poor, seriously constrains the condition that land uses, while because self-priming effect is poor, also between
What is connect affects lift, and performance is poor on lift compared with this programme；And to lead to pump interior hydraulic pressure excessively high for tandem impeller,
And pump the excessively high internal structure that liquid can be caused to penetrate into motor damage motor of internal pressure.
Spy is with the national utility model of utility model device and II-Patent No. of the prior art 201420134414.9
