Description
Technical field
The utility model relates to centrifugal pump technical field, is specifically related to a kind of efficient oil transportation centrifugal pump.
Background technique
At present, centrifugal pump is mainly installed and is formed by parts such as the pump housing, impeller, axle, axle sleeve, pump cover and strut bearings, and impeller is arranged in the pump housing by axle, axle sleeve.When heavy crude producing, because viscous crude has, hydrocarbon content is low, paraffin content is few, colloid and bitumen content are high, the characteristics such as solidifying point is low, poor fluidity, need to carry out viscosity reduction processing to viscous crude, generally in pipeline, by the mode of heating, viscous crude is carried out to viscosity reduction processing now, but in centrifugal pump, the fluid entering in the pump housing is easily bonded on impeller and the pump housing, and the high surface friction drag of viscosity is large, the oil transportation timeliness that has reduced oil transportation centrifugal pump, has reduced working efficiency, also easily shortens the working life of centrifugal pump simultaneously.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provide a kind of simple in structure, reasonable in design, can reduce fluid and enter the viscosity in the pump housing, reduce the frictional force of fluid and pump, can improve transfer efficiency, extend the working life of pump, the efficient oil transportation centrifugal pump that can increase work efficiency.
Its technological scheme is: efficient oil transportation centrifugal pump, comprise the pump housing, pump cover, impeller and impeller shaft, one end of described impeller shaft is connected with drive motor, the other end of described impeller shaft is provided with impeller, the described pump housing is arranged on pump cover, the front end of the described pump housing is provided with admission chamber, the top of the described pump housing is provided with liquid outlet, in described admission chamber, be provided with the inducer being connected with impeller shaft, the inside of described inducer is provided with heating pipe, the front end of described admission chamber is provided with air mix facilities, described air mix facilities comprises the dilution tube being communicated with admission chamber and is arranged on multiple spray holes of dilution tube periphery, described spray hole is connected with outside liquid inlet pipe by pipeline, the pump housing inwall in described impeller outside is provided with electromagnetic cleaner.
The width of the liquid outlet channel of described impeller is caudad increased gradually by import.
Described spray hole is evenly arranged on described dilution tube, and opening direction is consistent with liquid flow direction.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, and can reduce fluid and enter the viscosity in the pump housing, reduce the frictional force of fluid and pump, can improve transfer efficiency, extend the working life of pump, can increase work efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
With reference to Fig. 1, efficient oil transportation centrifugal pump, comprise the pump housing 1, pump cover 2, impeller 3 and impeller shaft 4, one end of described impeller shaft 4 is connected with drive motor, the other end of described impeller shaft 4 is provided with impeller 3, the described pump housing 1 is arranged on pump cover 2, the front end of the described pump housing 1 is provided with admission chamber 5, the top of the described pump housing 1 is provided with liquid outlet 6, in described admission chamber 5, be provided with the inducer 7 being connected with impeller shaft 4, the inside of described inducer 7 is provided with heating pipe 8, the front end of described admission chamber 5 is provided with air mix facilities, described air mix facilities comprises the dilution tube 9 being communicated with admission chamber 5 and the multiple spray holes 10 that are arranged on dilution tube 9 peripheries, described spray hole 10 is connected with outside liquid inlet pipe 11 by pipeline, the pump housing 1 inwall in described impeller 3 outsides is provided with electromagnetic cleaner 12.
The width of the liquid outlet channel 13 of described impeller 3 is caudad increased gradually by import.Can increase like this fluid area, meet the mobile requirement of viscous crude, improve pump efficiency.
Described spray hole 10 is evenly arranged on described dilution tube 9, and opening direction is consistent with liquid flow direction.When diluent liquid is water, can form water membrane at fluid outer surface like this, thereby reduce the frictional force of fluid and external casing, improve oil transportation efficiency.Certainly, diluent liquid also can be viscosity depressant etc.
Before the admission chamber 5 of the pump housing 1, set up air mix facilities, can make viscous crude dilute entering before the pump housing 1, by liquid such as the viscosity depressant in outside liquid inlet pipe 11 or water, by spray hole 10, at the outer surface of fluid, form water membrane or fluid is directly diluted, can reduce like this friction of fluid and the pump housing 1 inwall, improve oil transportation efficiency, when arriving after admission chamber 5, by inducer 7, can not only prevent cavitation phenomenon, and can to fluid, carry out heating, viscosity reducing by inner heating pipe 8, fluid flows out by liquid outlet 6 under impeller 3 drives, prevent from entering the frictional force that the pump housing 1 is rear and impeller product 3 is raw excessive and affecting working efficiency, by being set on the inwall at the pump housing 1, electromagnetic cleaner 12 can carry out breakdown of emulsion and viscosity reduction effect to viscous crude, can effectively prevent the generation of fouling and pitch deposition, guarantee the unimpeded of liquid flow channel for oil.
The utility model is simple in structure, reasonable in design, can reduce fluid and enter the viscosity in the pump housing, reduces the frictional force of fluid and pump, can improve transfer efficiency, extends the working life of pump, can increase work efficiency.
