Abstract
The utility model provides a low-flow and high-pressure rotary jet pump, comprising a rotor body and a collecting pipe, wherein the rotor body consists of an impeller and a rotor cavity, and the collecting pipe consists of a diffusion section and an outlet pipe; the impeller and an impeller outlet are arranged in the rotor cavity; the diffusion section of the collecting pipe is also arranged in the rotor cavity; the outlet pipe of the collecting pipe is connected to outside; and the section of the inner cavity of the diffusion section of the collecting pipe is designed into a data pit shape, the section of the inner cavity of the outlet pipe is designed into an oval shape, and the integral appearance of the collecting pipe is in a streamline shape, so that the loss of liquid flowing around the collecting pipe is reduced, the kinetic energy of the liquid flow is converted into high-pressure energy to output, and the rotary jet pump is low in flow rate and high in lift.
Description
Technical field
The utility model relates to a kind of pump, the small flow that particularly in petrochemical equipment, oil-gas field development, uses, high-lift a kind of small flow high-pressure rotary jet pump.
Background technique
In industries such as petrochemical industry, Oil-Gas Field Development Engineering, water filling draining, papermaking, mining, powder metallurgy, need to use small flow, high-lift pump.Usually people often replace with centrifugal pump.Though the centrifugal pump flow is little, its lift is low, and in order to improve lift, people just use multistage centrifugal pump.Multistage centrifugal pump not only cost is high, and friction points is many, and rate of fault is high, and efficient is low.
The model utility content
The technical problem that the utility model will solve is: a kind of small flow high-pressure rotary jet pump is provided, and not only flow is little but also lift high for it.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of small flow high-pressure rotary jet pump, comprise rotor body and header pipe, and said rotor body is made up of impeller and rotor chamber, and said header pipe is made up of diffuser and outer pipe; Said impeller and impeller outlet are arranged in the rotor chamber; The diffuser of said header pipe also is arranged in the rotor chamber, and the outer pipe of said header pipe links to each other with the external world, wherein; The diffuser inner chamber section configuration of said header pipe is a jujube nuclear shape, and the outer pipe inner chamber section of said header pipe is oval.
In described small flow high-pressure rotary jet pump, be preferably, said impeller adopts the composite impeller structure.
In described small flow high-pressure rotary jet pump, be preferably, said header pipe is a double pipe structure.
The described small flow high-pressure rotary of the utility model jet pump; The diffuser inner chamber crosssection shape design of its header pipe becomes jujube nuclear shape; Outer pipe inner chamber Section Design ovalisation makes the header pipe monnolithic case become streamlined, the loss when streaming header pipe to reduce liquid; Thereby can be converted into high pressure energy output to the kinetic energy of flow, not only flow is little but also lift high to make said rotary jet pump.
Description of drawings
Fig. 1 is the structural representation of the said small flow high-pressure rotary of the utility model jet pump.
Embodiment
Below combine accompanying drawing that the utility model is made more detailed description with embodiment.Present embodiment only is the description to the utility model preferred forms, and the scope to the utility model does not have any restriction.
Embodiment
As shown in Figure 1, said small flow high-pressure rotary jet pump comprises rotor body 1 and header pipe 2, and said rotor body 1 is made up of impeller 11 and rotor chamber 12, and said header pipe 2 is made up of diffuser 21 and outer pipe 22; Said impeller 11 and impeller outlet are arranged on 12 li of rotor chamber; The diffuser 21 of said header pipe also is arranged on 12 li of rotor chamber; The outer pipe 22 of said header pipe links to each other with the external world; Wherein, the inner chamber section configuration of the diffuser 21 of said header pipe can be designed to jujube nuclear shape or other analogous shapes, and the inner chamber section of the outer pipe 22 of said header pipe can be designed to ellipse or circle.Preferably, said impeller 11 can adopt the composite impeller structure.Said header pipe 2 can adopt double pipe structure, can certainly adopt the single tube structure.
During the work of small flow high-pressure rotary jet pump, liquid is managed into people's impeller from inhaling the people, under action of centrifugal force, gets into rotor chamber.Fixing header pipe is collected the kinetic energy liquid in the rotor chamber, with the kinetic energy of liquid convert into pressure can, discharge the pump housing through outer pipe.It is simple in structure, need not volute casing, and also volume is little, and amount of maintenance is little, and expense is low, long service life.Simultaneously; The diffuser inner chamber crosssection shape design of said header pipe is become jujube nuclear shape; Outer pipe inner chamber Section Design ovalisation makes the header pipe monnolithic case become streamlined, the loss when streaming header pipe to reduce liquid; Thereby can be converted into high pressure energy output to the kinetic energy of flow, not only flow is little but also lift high to make said rotary jet pump.
Claims (3)
1. a small flow high-pressure rotary jet pump comprises rotor body and header pipe, and said rotor body is made up of impeller and rotor chamber, and said header pipe is made up of diffuser and outer pipe;
Said impeller and impeller outlet are arranged in the rotor chamber, and the diffuser of said header pipe also is arranged in the rotor chamber, and the outer pipe of said header pipe links to each other with the external world, it is characterized in that:
The diffuser inner chamber section configuration of said header pipe is a jujube nuclear shape, and the outer pipe inner chamber section of said header pipe is oval.
2. small flow high-pressure rotary jet pump according to claim 1 is characterized in that: said impeller adopts the composite impeller structure.
3. small flow high-pressure rotary jet pump according to claim 1 is characterized in that: said header pipe is a double pipe structure.
