Piece.
As a preferred scheme of the present utility model, the impeller has 15.
The utility model at work, mechanical seal rinsing water before opening during pump startup, without being poured water into pump, direct use
Outer flushing replaces water-pouring process, opens self-priming impeller after pump and rotates at a high speed, inducer, self-priming impeller and seal case approximately form with
Water ring vacuum pump, entrance is formed vacuum, by the air in pipeline by inducer, and be discharged into through self-priming impeller in seal case
Gas exhaust piping, until by air emptying in pipeline, medium enters stage casing under atmospheric pressure, and pump enters normal operation rank
Section, medium enter first stage impeller by inducer runner, and impeller rotation under pump shaft drive is done work to medium, and medium is again through stator
Subordinate's impeller is flowed into, and so on, medium flows successively through every one stage impeller, and pressure constantly raises, until passing through afterbody leaf
Wheel discharges the pump housing by outlet section.
The utility model has the following advantages that compared with prior art：
1st, impeller of the present utility model can install 15 impellers up to 15 grades, greatly improve the lift of pump, H-Max
Up to 2000m；
2nd, without filling pump before pump is opened, direct self-priming can be achieved, and self-priming time is very short, can avoid long-term storage mediums
And caused corrosion；
3rd, the poisonous and harmful operating mode of HTHP can be applied to, can convey with Korrosionsmedium, containing foam medium, contain
There are the medium of gas, the medium containing granule foreign, medium for easily being vaporized containing light component etc.；
4th, 7-9 rice has been arrived in suction lift lifting, and self-priming time is short, and self-priming can be completed in 10s, can be at -30 DEG C extremely
