Abstract
The utility model relates to a single end multistage labyrinth screw pump, belonging to the technical field of universal engineering equipment. At present, the labyrinth screw pump comprises a labyrinth screw body while the single end multistage labyrinth screw pump comprises two or more than two labyrinth screw bodies. Therefore, the labyrinth screw pump can make use of the performance ascendancy of a plurality of labyrinth screw bodies and overcome the performance limitation of one labyrinth screw body.
Description
Technical field the utility model relates to a kind of single-ended multistage labyrinth screw pump, belongs to general engineering equipment technical field.
Background technique is present, the labyrinth screw pump of domestic and international design, and the patent No. is ZL91219777.3, its structure is as shown in Figure 1.Be transferred medium under motor 1 rotates, flow in the working cavity that the pump rotor 4 that is installed in above the pump shaft bearing 3 and the pump housing 5 form, by 6 eliminatings of pump discharge flange by pump inlet flange 2.
Labyrinth screw pump is made up of a labyrinth heliconid at present.The working cavity that the pump rotor 4 of labyrinth screw pump and the pump housing 5 are formed is called as the labyrinth heliconid.On pump rotor 4 outer surfaces and the pump housing 5 internal surfaces, be covered with screw thread respectively.
Studies have shown that spirochetal length in the labyrinth of labyrinth screw pump and diameter (within the specific limits) are directly proportional with the pressure of labyrinth screw pump.
Studies have shown that the labyrinth heliconid design of labyrinth screw pump is crucial.
The summary of the invention the purpose of this utility model is a kind of single-ended multistage labyrinth screw pump of design.Be the labyrinth screw pump of forming by a labyrinth heliconid existing, be designed to two (a labyrinth heliconid is an one-level, and a plurality of is multistage) or two labyrinth screw pumps that above labyrinth heliconid is formed.
This design can be brought into play the performance advantage that the spirochetal length in a plurality of labyrinths and diameter (within the specific limits) are directly proportional with the pressure of labyrinth screw pump.Can develop a kind of novel ultrahigh pressure, low-capacity pump.
This design can overcome the limitation that the spirochetal length in labyrinth and diameter (within the specific limits) are directly proportional with the pressure of labyrinth screw pump.
Description of drawings Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present utility model.
Embodiment is introduced below in conjunction with Fig. 1 and Fig. 2 accompanying drawing, and the 1st, pump motor, the 2nd, pump inlet flange, the 3rd, pump shaft bearing, the 4th, pump rotor, the 5th, the pump housing, the 6th, pump discharge flange.
Specifically introduce content of the present utility model.Be the pump rotor 4 and the pump housing 5 that the Fig. 1 that will design is made up of a labyrinth heliconid, be designed to the pump rotor 4 and the pump housing 5 that two or more labyrinth heliconids are formed.The order that the labyrinth heliconid is formed is descending arrangement successively.Fig. 2 pump rotor 4 and the pump housing 5 are made up of two labyrinth heliconids.An embodiment of the present utility model is that two labyrinth heliconids of diameter 100mm and diameter 80mm are formed.
Claims (1)
1, a kind of single-ended multistage labyrinth screw pump comprises pump motor, pump shaft bearing, the pump housing, pump rotor, pump inlet flange and pump discharge flange, it is characterized in that this labyrinth screw pump is made up of two or more labyrinth heliconids.
