The technical scheme is that：A kind of heavy duty detergent high suction depth formula dry type double entry pump, including base, motor, housing and
Impeller, motor and housing are installed on base, and impeller is arranged in housing and by motor drive connection, it is characterised in that：It is described
The upper surface of housing is provided with entery and delivery port, and impeller is located in the middle of housing cavity and forms two half-spirals with the side body of housing two
Suction chamber, impeller and housing middle casing one spiral pumping chamber of formation, water inlet is successively through semi-spiral suction chamber, impeller, spiral shell
The spinning hydroecium connectivity part mouth of a river；The entery and delivery port flange connects volute type water-in and water-out passage.
Further, integrally casting is formed for spiral pumping chamber and housing.
Further, the both sides of housing are encapsulated through left and right boring cover respectively, and the motor shaft of motor connects leaf through any boring cover
Wheel.
Further, left and right boring cover is respectively through left and right end cap positioning package impeller in housing.
Further, the helical structure of any semi-spiral suction chamber is divided into two parts, and a part is another on housing
Part is on the corresponding end cap in above-mentioned semi-spiral suction chamber side.
Further, volute type water-in and water-out passage is straight tube.
Further, volute type water-in and water-out passage is bend pipe, and the bend pipe angle of water-in and water-out passage is connected by flange to be adjusted
Section.
Further, motor is connected to any side of housing through connecting end cap, and the motor shaft of motor is sealed through mechanical seal
Wear and connect end cap in succession.
Further, encapsulated check-valves is set in exhalant canal.
The operation principle and process of the present invention：Rotated by motor impeller, discharge housing makes shell with the air in pipeline
Medium under atmospheric pressure, is pressed into pipeline by body with forming vacuum in pipeline, is inhaled by intake tunnel into half-spiral
Hydroecium, improve flox condition, it is ensured that the velocity field at impeller inlet be uniform, then by impeller by medium from spiral pressure water
Got in room, so as to improve pump efficiency.
Compared with prior art, the beneficial effects of the invention are as follows：The import of water pump uses semi-spiral suction chamber, improves stream
State, it is uniform for can ensure that the velocity field at impeller inlet, improves efficiency more than 25%, the possibility that reduction cavitation occurs
Property, increase 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 demand of multi-angle regulation pipeline, breach conventional awkward general layout, it is adaptable to because of typhoon, heavy rain, flood
The diversion irrigation when ponding Deng caused by and drought resisting, fire-fighting water intaking etc..
