Abstract
A axial-flow fluid compressor (pump, compressor, or flower) is composed of electric motor, drive shaft, blades fixed to drive shaft, rotor consisting of blades and casing, which are linked together, stator at both sides of rotor, and dynamic sealing ring between rotor and stator. Its advantages are high flow and output pressure, non fluid leakage and high efficiency.
Description
One, technical field
The present invention relates to mechanical engineering, particularly axial-flow pump, Axial Flow Compressor and axial fan.
Two, background technique
Axial flow turbomachine comprises various pumps, blower fan, compressor etc., and they all are the blade convection cell actings that utilizes on the high speed rotating impeller, improves the pressure energy and the kinetic energy of fluid.Because have radial clearance between blade and the housing, when impeller rotated, the fluid that exists high voltage terminal can leak to low voltage terminal by the gap, particularly this leakage rate has more deficiency when outlet end pressure increases.This just makes such mechanical outlet pressure be restricted, and has also greatly reduced this type of mechanical efficient.The machinery of prior art is only applicable to the occasion of big flow low-head.
Three, summary of the invention
Goal of the invention of the present invention provides a kind of novel axial-flow fluid compressed machinery and reach higher back pressure when keeping original big flow characteristics, and has higher working efficiency.This fluid compression engine tool can be used for compressed liquid, gas and gas-liquid two-phase fluid as required, is a kind of novel axial-flow fluid compression set.
The technological scheme that realizes the object of the invention is to solve like this: comprise motor and transmission shaft, be fixedly connected with blade on the transmission shaft, its improvements are also to comprise that blade and shell connect to form rotor, are provided with stator in the both sides of rotor, are connected by dynamic seal ring between rotor and the stator.
The present invention compared with prior art, the main feature of the novel axial-flow fluid compression set of this type is:
(1) diametric(al) blade or screw rod and the frame formation rotor that is connected as a single entity pivots during work simultaneously;
(2) add motive sealing between rotor and stator in case the fluid stopping body leaks;
(3) according to the characteristic that is compressed fluid, uniform section or tapering type cross section can be adopted in the rotor flow tract cross section;
(4) can add some blades simultaneously at rotor outer surface is used for heat radiation and plays the longitudinal balance effect.
According to above-mentioned said wooden characteristic feature of an invention as can be known, also have no escape of liquid, increase the advantage of pressure and flow velocity.Adapt to and make various axial-flow pumps, axial fan, Axial Flow Compressor etc.Novel axial-flow fluid compression set reaches higher back pressure when keeping original big flow characteristics, and has higher working efficiency.This fluid compression engine tool can be used for compressed liquid, gas and gas-liquid two-phase fluid as required, and good social and economic benefit are arranged.
Four, description of drawings
Fig. 1 is for leaving the structural representation in gap between prior art rotor and the cylindrical stator;
Fig. 2 is rotor of the present invention and the gapless leaf grating form structure of stator schematic representation;
Fig. 3 is the screw form structural representation of rotor of the present invention along the axial direction variable cross section.
Five, embodiment
Accompanying drawing 2,3 is two kinds of typical embodiments of the present invention;
Below in conjunction with accompanying drawing particular content of the present invention is described further:
With reference to shown in Figure 1, leave certain clearance between rotor and the cylinder type stator, when impeller rotated, the fluid that exists high voltage terminal can leak to low voltage terminal by the gap, and particularly this leakage rate can be more when outlet end pressure increases.
Shown in Figure 2, comprise that motor is connected on the transmission shaft, be fixedly connected with blade on the transmission shaft, comprise that also blade and shell connect to form rotor 3, be provided with stator 1,5 in the both sides of rotor 3, be connected by dynamic seal ring 2,4 between rotor 3 and the stator 1,5.This Placement is that rotor 3 is uniform section leaf grating form structure with stator 1,5, also can make the screw type structure.
Shown in Figure 3, rotor 3 is shaped as variable cross section or tapering type section form structure with stator 1,5.The axial-flow fluid compression set of this form structure adapts to the fluid variation that volume reduces gradually or increases in by compression.
Accompanying drawing 2,3 only is the present invention's two kinds of form structures wherein, in implementing process of the present invention, can occasion according to actual needs selects the axial-flow fluid compression set of different purposes form structures.Its form comprises that mainly the cross section of rotor 3 is cascade type or screw type.The cross section of rotor 3 is a variable cross section along the main shaft flow direction, and rotor 3 is shaped as variable cross section or uniform section or tapering type cross section rotor, and rotor 3 is shaped as multistage combined rotor.
Claims (4)
1, a kind of novel axial-flow fluid compression set, comprise motor and transmission shaft, it is characterized in that also comprising and be fixedly connected with blade on the transmission shaft, form rotor (3) by transmission shaft, blade, shell, be provided with stator (1,5) in the both sides of rotor (3), be connected by dynamic seal ring (2,4) between rotor (3) and the stator (1,5).
