Description

Vortex pump

Technical field

The utility model relates to a kind of vortex pump, is the equipment that the soiling solution that has impurity is carried, and belongs to field of machining.

Background technique

The industrial wastewater that produces in field of machining need be delivered in the filter plant with transh pump and handle, there are a lot of shortcomings in existing transh pump, as: the one, damage in impeller is serious, needs often to change, anti-cavitation erosion ability, and the frictional loss between liquid is big; The 2nd, the inside cavity structure of pump is not smooth, hinders the outflow of impurity, blocking phenomenon often occurs; The 3rd, the coupling processed complex, coaxality is poor, the rotation serious wear, motor damages easily, and noise is big; The 4th, pump size under soiling solution can not in time be adjusted with different applying working conditions etc.

Summary of the invention

The purpose of this utility model is to improve the deficiency that exists in the prior art, and a kind of novel structure is provided, and runner is smooth and easy, is difficult for stopping up impurity, and wearing and tearing are few, noise free, vortex pump easy to maintenance.

The technical solution of the utility model is: a kind of vortex pump, it has mounting plate, be provided with motor on mounting plate, be provided with connecting body below it, the other end of connecting body is connected with cavity, cavity is provided with water inlet and water outlet, be provided with coupling shaft in connecting body, an end of coupling shaft is connected with motor shaft, and the impeller in the other end and the cavity is connected, characteristics are that the inner flow passage cross section of cavity is outwards to be involute from central shaft to launch shape.

In order to reduce the friction that has relative movement between liquid and the impeller, the leaf dish on the described impeller can be recessed arc shape leaf dish.

In order to adjust the coaxality between motor shaft and the coupling shaft and to reduce running noise, described motor shaft can be connected for plug-in type with the Placement of coupling shaft, is provided with coupling in both joints.

Compared with the prior art, the utlity model has following advantage:

1, because the inside cavity flow channel shape of this vortex pump has utilized principle of forming involute, outlet passage is enlarged gradually, not only can slow down the flowing velocity after water is thrown away by impeller, reduce the loss of energy, more help the conversion between energy.Under the high speed rotating of impeller drives, do centrifugal motion when the liquid that has impurity, when running to big water outlet place, can as much as possible kinetic energy be converted into the pressure energy, be convenient to the output of current, can not form obstruction.

2, because impeller high speed rotating in cavity can form powerful vortex, and this leaf blade disk adopts recessed arc shape, makes impeller channel present arc, according to hydromechanical principle, and the eddy current shape that forms when the intracavity liquid that fits like a glove is stirred.Impeller is when high speed rotating is stirred liquid like this, and liquid will reduce greatly with relative friction between impeller, not only reduce the wearing and tearing between impurity and the impeller, prolongs impeller working life, and is easy to liquid and flows out, and the iron filings of≤50mm can not form obstruction.

3, change the linkage structure of motor shaft and coupling shaft, improve coaxality, make its rotation steadily, reduce noise, prolongation motor working life.

Below in conjunction with drawings and Examples the utility model is done at length and to be explained.

Embodiment

Referring to Fig. 1, this vortex pump is the boundary with mounting plate 9, following is installed under the container panel, installation motor 1 on mounting plate 9, connecting body 6 is installed below, the other end of connecting body 6 is the cavity 4 of pump, cavity 4 is an integrally casting, be respectively equipped with water inlet 11 and water outlet 2 on its bottom and the sidewall, the inside cavity smooth surface, and the cross section of runner is outwards to be involute from central shaft to launch shape (referring to shown in Figure 2), is provided with coupling shaft 7 in connecting body 6, one end of coupling shaft 7 is connected with the motor shaft 10 of motor 1, and the impeller 5 in the other end and the cavity 4 is connected.

Working principle: the liquid that contains impurity enters cavity by water inlet, and impeller carries out high speed rotating under the drive of motor, forms powerful vortex in cavity, is blended in the impurity in the liquid, is directly thrown away under the drive of centrifugal motion.Because cavity body structure utilized principle of forming involute, its outlet passage enlarges gradually, can be discharged smoothly when the liquid that therefore has impurity runs to big water outlet place, and the iron filings of≤50mm can not form obstruction.

In order to reduce the friction between liquid and impeller, the leaf dish 12 on the impeller 5 can be designed to recessed arc shape leaf dish, referring to Fig. 3-shown in Figure 5.Leaf dish 12 is similar to be recessed horn mouth shape, corresponding blade 13 and its curved connection, whole impeller channel presents arc, impeller is when high speed rotating is stirred liquid like this, the eddy current shape that has coincide and formed when the interior liquid of cavity is stirred, reduce the friction between liquid (impurity) and impeller, be easy to liquid and flow out, and prolonged impeller working life.

In order to adjust the coaxality between motor shaft and the coupling shaft and to reduce noise, the motor shaft 10 of this vortex pump can be designed as plug-in type with the Placement of coupling shaft 7 and is connected, referring to shown in Figure 6, the fore-end of motor shaft 10 is inserted in the coupling shaft 7, in both joints a coupling 8 is installed then.Motor shaft rotates steadily when working like this, the motor long service life, and noise is low.

This vortex pump can connect into water pipe 3 at water inlet 11 places, and the length of water inlet pipe 3 can arbitrarily extend or remove as required.

This pump is fit to the lathe of present many rebuilding old equipments, because its drain gully is too low, filter plant can not be installed on the ground, need the transition water tank to collect sewage, therefore can use this vortex pump to connect behind one section water inlet pipe the sewage (impure) of cabinet leg extracted out to be transported to filter plant and to filter.

The utility model is suitable for the conveying of industrial wastewaters such as lathe, automobile, bearing, steel rolling and is used for the riverbed mud of industries such as improvement of river bed, food, chemical industry, papermaking, food liquid, paper making pulp etc. promoting conveying, can with various filter plants and the independent supporting use of lifting means.
