Section.
Further, motor is connected to any side of housing through connection end cap, and the motor shaft of motor seals through mechanical seal
Wear and connect connection end cap.
Further, encapsulated check-valves is set in exhalant canal.
Operation principle and process of the present utility model：Rotated by motor driven impeller, discharge housing with the air in pipeline,
Housing is set under atmospheric pressure, medium to be pressed into pipeline with forming vacuum in pipeline, enter semi-spiral by intake tunnel
Shape suction chamber, improve flox condition, it is uniform to ensure the velocity field at impeller inlet, then by impeller by medium from spiral
Got in pumping chamber, so as to improve pump efficiency.
Compared with prior art, the beneficial effects of the utility model are：The import of water pump uses semi-spiral suction chamber, changes
Kind fluidised form, it is uniform for can ensure that the velocity field at impeller inlet, improves efficiency more than 25%, and what reduction cavitation occurred can
Energy property, increases the service life；Entery and delivery port is arranged in the top of housing, and the established angle of water-in and water-out passage is adjusted by flange
Degree, can meet the needs of multi-angle regulation pipeline, conventional awkward general layout be breached, suitable for because of typhoon, heavy rain, flood
The diversion irrigation when ponding Deng caused by and drought resisting, fire-fighting water intaking etc..
