From 1 data analysis of table：
1. 14 mounting means of impeller and independent self-priming water supply chamber 17 of the series connection of this programme setting, self-priming excellent, series connection
Impeller 14 increase active force, while good self-priming effect meets land use condition, the coordination of the two has device
There is a superior lift, but independent self-priming water supply chamber 17 and the impeller 14 of series connection result in that pump internal pressure is excessively high, and overflow pipe 3 is ingenious
Solve the problems, such as this, and aial flow impeller 15 plays the role of playing impeller 14 supercharging, more than very low suction people
Amount just disclosure satisfy that the need satisfaction of the total head overload free demand of total head；
2. in the prior art I：The quantity of impeller is limited to the impeller mounting means of dress, so as to limit lift, although the dress
It puts the pedestal there is provided self-priming water supply function to disclosure satisfy that land use condition, the defects of due to the impeller of dress, results in and raise
Journey 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 liquid to be caused to ooze
Enter the internal structure of motor damage motor, although the water outlet of device setting pumps the problem of internal pressure is excessively high to alleviate, but
The problem of bringing leakage；Particularly the device does not have the overload free ability of total head；
3. in the prior art II：The impeller mounting means of series connection relative to the prior art I for the impeller mounting means of dress,
With more excellent lift, but the impeller of the device water pump is arranged to entire body structure with water inlet, it is impossible to generate fine
Pressure differential, therefore self-priming effect is poor, seriously constrains the condition that land uses, while because self-priming effect is poor, to understand
Certainly the problem device can only separately set water-absorbing tank, while also indirectly affect lift, compared with this programme on lift performance
It is poor；And to lead to pump interior hydraulic pressure excessively high for tandem impeller, and pump that internal pressure is excessively high to cause liquid to penetrate into motor damage motor
Internal structure.
Spy is with the china national practical new-type patent of apparatus of the present invention and II-Patent No. of the prior art 201420134414.9
A kind of amphibious self-priming sand discharging pump of movable type is disclosed to be compared, by the prior art I -- Patent No. 201320592719.X's
China national practical new-type patent discloses a kind of technical characteristic of the self-priming water supply pedestal of amphibious multistage pump in a manner of introducing
It is compared as a control group, self-priming water supply pedestal is connected with the pump housing by bolt seal：

China national practical new-type patent disclose a kind of amphibious multistage pump self-priming water supply pedestal technical characteristic, with the prior art
The china national practical new-type patent of II-Patent No. 201420134414.9 discloses a kind of amphibious self-priming sand discharging pump skill of movable type
Art feature is combined design；Control group has outstanding lift, but due to there is no design overflow pipe, it is impossible to while in solving
The problem of leakage and leakage, therefore, control group, can lead to serious interior leakage problem, and the device does not have the energy of overload protection
Power, it is impossible to realize the overload free function of total head.
In summary：It is arranged at intervals between the self-priming water supply chamber 17 of the present apparatus and the pumping chamber 13 that impeller 14 is set, so as to
A relatively closed environment is formd, and then greatly provides the suction capacity of the pump housing, avoids and separately sets water-absorbing tank, realize
Amphibian function；It is equipped in pumping chamber 13 and is sheathed on impeller 14 multistage in shaft, the impeller 14 of series design increases
The lift of the pump housing, but tandem impeller 14 can cause hydraulic pressure in pumping chamber 13 excessively high, and pump that internal pressure is excessively high to lead to liquid
The internal structure that mechanical sealing chamber 12 damages motor is penetrated into, the present apparatus cleverly devises overflow pipe 3, not only effectively solves
The problem of internal pressure is excessively high is pumped, and realizes internal cycle, so as to effectively solve the problems, such as liquid leakage environmental pollution；
The aial flow impeller 15 of present apparatus design simultaneously, plays the role of supercharging to impeller 14, can efficiently control flow, ensures
Amphibious motor total head No-mistake Principle, therefore technical scheme of the present invention is compared with prior art, has prominent essence
Property feature and significant progress.
