The pressurized water chamber for the oil transporting main pump has the advantages that the pressurized water chamber for the oil transporting main pump improves flow fields in the pressurized water chamber and eliminates residual radial force of the pressurized water chamber, simultaneously can be suitable for changing of engineering parameters just by replacing the expansive flow device and the impeller under the situations that the volute chamber is not replaced and the efficiency is guaranteed not to change.
Description
Technical field
The utility model relates to a kind of pumping chamber that is used for the oil transportation main pump of petroleum industry.
Background technique
The oil transportation main pump is one of visual plant in the long Distance Transmission of crude oil or product oil.The oil transportation main pump must be able to adapt to the round-the-clock environment in many regions, also must can realize unmanned, telecontrol, so the user has higher requirement to the oil transportation main pump.Pumping chamber is meant the flow channels of impeller outlet to the pump discharge flange.Its effect is to collect the high-speed liquid that flows out from impeller, and converts most of kinetic energy of liquid into the pressure ability, then through being provided with and the terminal outlet(discharge) flange of outer pipe, with the impeller inlet of said liquid introducing pressure supply water pipe or back level impeller.At present, what the oil transportation main pump often adopted is single snail shell coiling pumping chamber, and it not only plays a part to collect liquid, converts partially liq kinetic energy to pressure energy simultaneously.It requires pressure distribution even in design, to reduce the radial force of working fluid, reduces the water conservancy loss in the pumping chamber, improve the transfer efficiency of oil transportation main pump, but crude oil is the liquid of thickness, through pumping chamber the time, can produce the obvious speed gradient.And the radial force of how eliminating in single pumping chamber of scroll casing is one of the technical barrier in affiliated field always.
The model utility content
The purpose of the utility model is in order to overcome the deficiency of existing technology, a kind of pumping chamber that is used for the oil transportation main pump to be provided, and it helps to reduce the radial force of liquid in pumping chamber.
A kind of technological scheme that realizes above-mentioned purpose is: a kind of pumping chamber that is used for the oil transportation main pump comprises a spirality flow channels; Said spirality flow channels flows between the excircle of device in the inwall and the expansion of spiral case chamber;
Said spiral case chamber is connected to outlet pipe;
Said expansion stream device is socketed on the excircle that is built in the indoor impeller of said spiral case; Said expansion stream device comprises the expansion stream device blade that is provided with along the circumference of said expansion stream device, forms the expansion stream device runner of said expansion stream device between adjacent two said expansion stream device blades.
Further, the section of said spirality flow channels is a trapezoidal cross-section.
Further, said spiral case chamber is single volute type spiral case chamber.
Further, the end of said outer pipe is provided with outlet(discharge) flange.
Further, between the inwall of the axial two ends of said impeller and said spiral case chamber impeller ring and casing ring are set.
Adopted a kind of technological scheme that is used for the pumping chamber of oil transportation main pump of the utility model; Be that the stream device is expanded in socket on the excircle of said impeller, said pumping chamber is the technological scheme of the spirality flow channels between the inwall of excircle and said spiral case chamber of said expansion stream device.Its technique effect is: improve liquid in said pumping chamber the flow field and eliminate the remaining radial force of said pumping chamber; Do not changing under the constant situation of said spiral case chamber and guaranteed efficiency simultaneously, only needing replacing expansion stream device and impeller just can adapt to the change of engineering parameter.
Description of drawings
Fig. 1 is a kind of radial structure schematic representation that is used for the pumping chamber of oil transportation main pump of the utility model;
Fig. 2 is a kind of axial arrangement schematic representation that is used for the pumping chamber of oil transportation main pump of the utility model.
Embodiment
See also Fig. 1 and Fig. 2, in order to understand the technological scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain:
Consult Fig. 1 and Fig. 2, a spiral case chamber 1 that is connected with outlet pipe 11 is provided with impeller 2 in the said spiral case chamber 1; Stream device 3 is expanded in socket on the excircle of said impeller 2, and said expansion stream device 3 is an annular; Said expansion stream device 3 comprises the expansion stream device blade 32 that is provided with along the circumference of said expansion stream device 3; Form the expansion stream device runner 31 of said expansion stream device 3 between adjacent two said expansions stream device blades 32, the described pumping chamber of the utility model is a formation spirality flow channels 4 between the inwall of excircle and said spiral case chamber 1 of said expansion stream device 3.
The purpose of design is like this: improve liquid in said pumping chamber the flow field and eliminate the remaining radial force of said pumping chamber; Do not changing under the constant situation of spiral case chamber and guaranteed efficiency simultaneously, only needing the said expansion stream of replacing device 3 and said impeller 2 just can adapt to the change of engineering parameter.These 2 all traditional pumping chambers are to realize.
Because in the present embodiment, said spiral case chamber 1 is single volute type spiral case chamber, so a kind of pumping chamber that is used for the oil transportation main pump in the utility model belongs to single snail shell coiling pumping chamber.The purpose of design is like this:
Help to reduce the cross-sectional area of said outlet pipe 11 ends, reduce the bore of said outlet(discharge) flange 12, reduce the flow velocity of liquid, reduce the local resistance loss of said liquid at terminal 11 places of said outer pipe in said outer pipe 11 tail ends
In the present embodiment; The section configuration of said spirality flow channels 4 is trapezoidal; The purpose of design is like this: liquid flows out in said expansion stream device runner 31, flows in the process of said spirality flow channels 4, flows along oblique line directions; The just in time identical liquid of the section of said spirality flow channels 4 flows the streamline that device runner 31 flows to said spirality flow channels 4 from said expansion, can reduce the hydraulic loss of liquid in pumping chamber like this.Liquid through said outer pipe 11, is discharged said pumping chamber through after the said spirality flow channels 4.
In addition, in order to strengthen the sealing of said pumping chamber, impeller ring 21 and casing ring 13 are set between the inwall of the axial two ends of said impeller 2 and said spiral case chamber 1.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
