Abstract

The present invention relates to a double end compound tooth type labyrinth screw pump which belongs to the technical field of universal engineering equipment. The principle of the pump is to operate by depending on a thread tooth type; at present, the tooth type of the pump is in a single tooth type. The tooth type of the pump can be designed into a rectangle, a trapezoid, a semicircle, etc. The research proves that each tooth type has unique performance advantages, but each tooth type has fatal disadvantages. The present invention is designed into a compound tooth type, and thus, the performance advantages of each tooth type can be exerted.

Description

Both-end composite tooth-shape labyrinth volute pump

Technical field

This invention relates to a kind of both-end composite tooth-shape labyrinth volute pump, belongs to general engineering equipment technical field.

Background technique

At present, the both-end feed liquor formula labyrinth screw pump of design can be offset the axial force of pump in theory fully both at home and abroad, improves the life-span of pump and increases pump delivery.The patent No. is ZL97224218.X, and its structure is transferred medium under motor 1 rotates as shown in Figure 1, is flowed 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.

This pump principle is to rely on thread tooth type work, and this pump gear type all is single flute profile at present.The working cavity of being made up of the pump rotor 4 and the pump housing 5 is called as the labyrinth heliconid.Be covered with the multiple thread of being made up of single flute profile respectively on pump rotor 4 outer surfaces and the pump housing 5 internal surfaces, according to different designing requirements, this pump gear type can be designed to rectangle, triangle, trapezoidal and semicircle etc. respectively.

Studies have shown that every kind of flute profile all has the particular performances advantage, but every kind of flute profile all has fatal deficiency.

The flute profile of labyrinth screw pump (pump rotor and the pump housing) design is crucial.

Summary of the invention

The purpose of this invention is a kind of both-end composite tooth-shape labyrinth volute pump of design.Be a part of screw thread that will have a kind of pump rotor of flute profile, change other flute profile screw thread into and be distributed on the pump rotor.This design can be given full play to the performance advantage of every kind of flute profile, and can overcome every kind of distinctive deficiency of flute profile.

Description of drawings

Fig. 1 is the structural representation of prior art, and Fig. 2 is the structural representation of this invention.

Embodiment

Introduce below in conjunction with Fig. 1 and Fig. 2 accompanying drawing, 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 invention.Be a part of screw thread that Fig. 1 has been had a kind of pump rotor 4 of flute profile, change other flute profile screw thread into and be distributed on the pump rotor 4.Fig. 2 pump rotor 4 is composite tooth-shapes.Embodiment's flute profile of this invention is that triangle becomes with semicircle screw thread complex group.

Claims (1)

1. a both-end composite tooth-shape labyrinth volute pump comprises pump motor, pump shaft bearing, the pump housing, pump rotor, pump inlet flange and pump discharge flange, it is characterized in that the thread tooth type of pump rotor is formed by two or more flute profile is compound.
