Abstract
The utility model discloses a kind of acid and alkali-resistance turbocharging centrifugal pumps, belong to centrifugation pump technical field.The output end of the motor is connect with enclosed impeller, and enclosed impeller is located inside integral type rear cover and integral type front cover, the integral type rear cover is connected to motor by attachment base, the inner wall of the integral type rear cover and integral type front cover is provided with turbine-like diversion trench, liquid pressure flow when by Scroll-type diversion trench is gradually amplified and then is directed to pump chamber outlet, liquid is when reaching pump chamber outlet after passing through the diversion trench between front cover rear cover under the centrifugal action of impeller, pump chamber entrance under closed environment forms vacuum, the liquid of pump chamber entrance is inhaled into pump chamber again, so as to complete the cycle operation of pumping；The pressure flow pumped simultaneously in the case where the front cover of close impeller and Scroll-type is with the water conservancy diversion cavity effect of rear cover all gets a promotion, and efficiency also increases accordingly.
Description
Technical field
The utility model relates to a kind of acid and alkali-resistance turbocharging centrifugal pumps, belong to centrifugation pump technical field.
Background technique
Centrifugal pump is designed according to centrifugal principle, and high-speed rotating impeller blade drives pumped (conveying) medium (such as water) to turn
It is dynamic, pumped (conveying) medium is thrown away, to achieve the purpose that conveying.Centrifugal pump has a lot of kinds, and clear water can be divided into from pumped (conveying) medium
Pump, transh pump, noncorrosive pump etc..
Centrifugal pump using very extensive, may be not only suitable for urban environmental protection, building, fire-fighting, chemical industry, pharmacy, dyestuff print
Dye, brewing, electric power, plating, papermaking, petroleum, mine, equipment cooling, oil tanker emptying etc., are also applied for clear water, seawater and have
Sour, basicity dielectric viscosity is less than or equal to 100 lis of ambers, solid content up to 30 ℅ chemical medium liquid below and with general paste
The slurry of shape.There is the defects of flow is less than normal, lift is lower, working efficiency is not high in use in existing acid and alkali-resistance centrifugal pump.
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 acid and alkali-resistance turbocharging centrifugations
Pump.
The acid and alkali-resistance turbocharging centrifugal pump of the utility model, it includes motor (1), integral type rear cover, foot prop, connection
Seat, enclosed impeller, integral type front cover and turbine-like diversion trench, the output end of the motor are connect with enclosed impeller, and
Enclosed impeller is located inside integral type rear cover and integral type front cover, and the integral type rear cover is connected by attachment base and motor
It connects, the inner wall of the integral type rear cover and integral type front cover is provided with turbine-like diversion trench, the motor bottom setting
There is foot prop.
Preferably, the enclosed impeller designs for inner wide and outer narrow.
Preferably, being provided with gasket between the integral type rear cover and integral type front cover.
The utility model has the beneficial effects that its structure is simple, design is rationally, preceding using the Impeller Design of inner wide and outer narrow
Cover with rear cover impeller periphery return guide trough at gradual change type turbine-like, pump in the running, liquid is closed inner wide and outer narrow
The flow velocity of liquid is improved under the extruding of box-like impeller and is imported into the diversion trench for the Scroll-type that front cover is formed with rear cover zoarium,
Liquid pressure flow when by Scroll-type diversion trench is gradually amplified and then is directed to pump chamber outlet, centrifugation of the liquid in impeller
After the lower diversion trench by between front cover rear cover of effect when arrival pump chamber outlet, the pump chamber entrance under closed environment is formed very
The liquid of sky, pump chamber entrance is inhaled into pump chamber again, so as to complete the cycle operation of pumping；Simultaneously in close impeller and
The front cover of Scroll-type all gets a promotion with the lower pressure flow pumped of water conservancy diversion cavity effect of rear cover, and efficiency also increases accordingly.
Detailed description of the invention
The present invention is described in detail by the following detailed description and drawings for ease of explanation,.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the decomposition texture schematic diagram of the utility model；
Fig. 3 is Scroll-type guide trough structure schematic diagram in the utility model.
Appended drawing reference: motor 1, integral type rear cover 2, foot prop 3, attachment base 4, enclosed impeller 5, integral type front cover 6, turbine
Shape diversion trench 7.
Specific embodiment
As shown in Figure 1-Figure 3, present embodiment use following technical scheme: it include motor 1, integral type rear cover 2,
Foot prop 3, attachment base 4, enclosed impeller 5, integral type front cover 6 and turbine-like diversion trench 7, the output end and envelope of the motor 1
Double shrouded wheel 5 connects, and enclosed impeller 5 is located inside integral type rear cover 2 and integral type front cover 6, the enclosed impeller 5
It is designed for inner wide and outer narrow, is provided with gasket between the integral type rear cover 2 and integral type front cover 6, after the integral type
Lid 2 is connect by attachment base 4 with motor 1, and the inner wall of the integral type rear cover 2 and integral type front cover 6 is provided with turbine-like
Diversion trench 7,1 bottom of motor are provided with foot prop 3.
Working principle are as follows: when work, 1 output shaft of motor drives enclosed impeller 5 to rotate, and enclosed impeller 5 uses inner width
Outer narrow design, under the squeezing action of close impeller 5, flow velocity is quickly improved and imported into 2 He of integral type rear cover liquid
In turbine-like diversion trench 7 between integral type front cover 6, when by circinate diversion trench 7, pressure flow is gradually amplified liquid
Then it is directed to pump chamber outlet, the pump chamber entrance under closed environment forms vacuum, the liquid or gas-liquid mixture of pump chamber entrance
Again it is inhaled into pump chamber, so as to complete the cycle operation of pumping.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
