Description
Technical field
The utility model relates to a kind of turbocharging acid and alkali-resistance self priming pumps, belong to self-priming pump technical field.
Background technique
The working principle of self priming pump is: first filling water (or itself having water in pump case) before starting in the pump housing.After starting
Impeller high speed rotation makes the water flow in impeller conduit to turbine, and at this moment entrance forms vacuum, makes to open into water non-return flap, suction line
Interior air enters in pump, and reaches outer rim through impeller conduit.Acid and alkali-resistance self priming pump belongs to self priming centrifugal pump, it has structure
It is compact, easy to operate.Steady, easy, corrosion-resistant, long service life of maintenance of running etc. is a little.Existing acid and alkali-resistance self priming pump exists
There are flows in use it is less than normal, lift is lower, working efficiency is not high the defects of.
Utility model content
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of turbocharging acid and alkali-resistance self-primings
Pump.
The turbocharging acid and alkali-resistance self priming pump of the utility model, it in motor, rear shaft seal, preceding axle envelope, integral type comprising sealing
Lid, foot prop, integral type rear cover, enclosed impeller, integrated molding front cover and Scroll-type diversion trench, the output shaft of the motor pass through
Wear in the middle part of integral type rear cover, and be provided with rear shaft seal and preceding axle envelope between output shaft and integral type rear cover, the motor it is defeated
Shaft one end is connect with enclosed impeller, and the integral type rear cover is connect by capping in integral type with front cover is integrally formed,
The enclosed impeller is located in integral type between capping and integral type rear cover, and the integral type rear cover bottom is provided with foot
Frame.
Preferably, capping and integral type rear cover are internally provided with Scroll-type diversion trench in the integral type.
Preferably, the enclosed impeller designs for inner wide and outer narrow.
Preferably, being provided with gasket between the integral type rear cover and integrated molding front cover.
The utility model has the beneficial effects that its structure is simple, design rationally, using the Impeller Design of inner wide and outer narrow, in
Cover with rear cover impeller periphery return guide trough at gradual change type turbine-like.In the running, liquid is in inner wide and outer narrow for pumping
The flow velocity of liquid is improved under the extruding of close impeller and is imported into the water conservancy diversion of the middle Scroll-type for covering and being formed with rear cover zoarium
In slot, liquid pressure flow when by swirl type diversion trench is gradually amplified and then is directed to pump chamber outlet, and liquid is in middle envelope
It is formed under the action of lid after gas-liquid separation and pump chamber entrance is formed into vacuum, the liquid or gas-liquid mixture of pump chamber entrance are inhaled again
Enter to pump chamber, so as to complete the cycle operation of pumping, while in middle capping the leading with rear cover of close impeller and Scroll-type
The flow for flowing the lower pumping of cavity effect is bigger, and pressure is higher, more efficient, more energy efficient.
