Abstract

An axial-flow pipe pump with integrative mechanical and electrical part of the utility model comprises a stator unit and a rotor unit. A squirrel-cage-shaped rotor winding is fixed to an impeller tip, and a fan and a sealing device are fixed to both sides of the rotor winding. A shaft bearing which is arranged at the center is added to form the rotor unit. The casing body of the pump and the motor stator are fixed in the axis direction by passing through a belt. The two casing bodies and the shaft share an interference fit to form the stator unit. The overflow sealing structure assures the safety of the motor and the shaft bearing. The utility model has the advantages of compact structure, high efficiency.

Description

Axial-flow pipe pump with integrative mechanical and electrical part

Electromechanical integration axial flow pipeline mounted pump is the device of a kind of pump fortune liquid of current collection machine and axial-flow pump one, can be used for farmland discharging-irrigating, and oil transport pipeline connects encourages, and discharge capacities such as electric power plant circulating water pump are bigger, the occasion that pressure head is less.

Existing axial-flow pump, pipeline mounted pump all be discrete with pump and motor be the main structure characteristics, how no matter arrange that compactness also is two rotors, two housings.Concerning axial-flow pump, because structural restriction, it needs long rotatingshaft to pass runner, and this is not only big to inventory charge, and affects the raising of flow efficiency.Pump and motor are discrete need to account for bigger space when mounted, brings certain difficulty to mounting arrangements.

Task of the present utility model provides a kind of current collection machine and pump one, and compact structure is saved material, the flow efficiency height, and it is few to take up space, and mounting arrangements is the axial flow pipeline mounted pump easily.

This axial flow pipeline mounted pump is made up of stator and rotor unit, and the squirrel cage rotor winding is fixed on the impeller outer edge, and fan and seal arrangement are fixed on its both sides, adds that the bearing at the center of being arranged in forms unified rotor unit; The housing and the motor stator of pump axially couple together with through bolt, and housing and axle interference fit constitute unified stator unit.Overflow hole is beaten at the center of being cast with on the housing, plays the guide plate of supporting effect simultaneously.Be cast with radiating fin on the motor stator shell, it plays a part stiffening rib simultaneously.Two circle square holes are circumferentially being opened in the housing both sides, play ventilation, the overflow effect.The excessive sealing configuration that seal ring seat and overflow hole constitute has guaranteed that the water clock of sealing can not immerse motor and bearing.

This model utility can be designed to tandem product according to specific speed and impeller diameter.Magna pump (more than the 60KW) stator is become adjustable with Blade Design.Miniature pump divides unidirectional, and two-way two kinds of structures (two-way is characteristics with the straight stator that parallels to the axis, and unidirectional stator will have one 12 °-20 ° angle with axis) are to be applicable to different needs.

The utility model current collection machine and pump one have only a rotor, a shell, and axially assembling makes it compact structure completely, saves material, the flow efficiency height, it is little to take up space, and processes, installs, arranges, easy to adjust.

Accompanying drawing 1: axial flow, stator blade, two-way pipeline mounted pump sectional arrangement drawing.

Accompanying drawing 2: axial flow, stator blade, two-way pipeline mounted pump drawing in side sectional elevation

With accompanying drawing 1,2 is that the utility model is described in further detail for embodiment:

This pump is made up of stator unit and rotor unit.

Stator unit is by axially locating ring (1), fair water cone (2), axle (3), setscrew nut (4), guide plate (29), gasket ring (6), seal ring (7), safety valve (8), housing (9), through bolt (10), and motor stator shell (11), motor stator (12) are formed.Guide plate (28) is cast as one with housing (9) and stator axis support (28).Overflow hole (5) is being left at guide plate (29) center.Opening ventilation overflow hole (22) on the housing (9).Motor stator is by silicon steel sheet (23), and staor winding (24) is formed.Housing (9) is solidly fixed with through bolt (10) with stator casing (11).Axle (3) and stator axis support (28) interference fit.Fair water cone (2) is threaded with stator axis support (28).Axially locating ring (1) is used to adjust the relative axial position of rotor and stator.Setscrew nut (4) is used for the axially locating of rotor with respect to axle (3).

Rotor unit is by squirrel cage rotor winding (13), impeller (14), and external sealed ring seat (15), fan (16), seal ring gland (17), seal ring (18), thrust-bearing (19), bearing (20), inner seal ring seat (21) is formed.Impeller (14) is by impeller outer edge (25), and blade (27), impeller shaft support (26) and form.Squirrel cage rotor winding (13) is fixed on the impeller outer edge (25).External sealed ring seat (15) is screwed on impeller outer edge (25), and inner seal ring seat (21) is connected with impeller shaft support (26) spiral shell strand.Fan (16) is fixed on impeller outer edge (25) both sides, rotation direction unanimity.The sealed gland of seal ring (18) (17) is pressed in the external sealed ring seat (15).

From the liquid that seal ring (18) overflows, walk around seal ring seat (15), overflow to the external world by ventilation overflow hole (22); Walk around seal ring seat (21) from the liquid that seal ring (4) overflows, excessive by the overflow hole (5) and the ventilation overflow hole (22) at blade (29) center to extraneous.

Rotor structure shown in the drawings is the structure of steel rotor, if use copper rotor, needn't add the rotor winding, and impeller itself is exactly a rotor.

Claims

1, electromechanical integration axial flow pipeline mounted pump is the device that is used for pump fortune liquid, and it is the integrated product of pump and motor, it is characterized in that:

1), the impeller of pump and rotor are united two into one.

To the steel impeller, fixing the squirrel cage rotor winding [13] of motor on the outer rim of impeller [14], form unified rotor.

To copper impeller, needn't add the rotor winding, impeller [14] itself is exactly the rotor winding of motor.

2), pump case and motor stator are connected as a single entity.

3), the guide vane while is as the support of stator axis support.

4), excessive sealing configuration: the overflow hole [5] in the external sealed ring seat [15], inner seal ring seat [21] guide vane, the ventilation overflow hole [22] on the housing [9] has constituted excessive sealing configuration.Its effect is to make the leakage current that unloads of sealing arrive extraneous.
