Abstract

The utility model relates to a centrifugal pump for counter-current training in a swimming pool. The centrifugal pump comprises a motor portion and a pump portion. The motor portion comprises a base, a front end, a wire box, a rotor assembly, a stator assembly, a rear end, a fan blade, a fan housing, etc. The pump portion comprises a pump casing, an impeller, a pump cover, an O-shaped ring, a mechanical seal, a bottom plate, etc. The motor rotor assembly is pressed in the base and then is filled with high-temperature resins, so that the centrifugal pump can be adapted to underground operation. The flow of the electric pump is super large, the closed-type impeller is used and labyrinth-type cooperation is adopted, thereby reducing pressure leakage and realizing high efficiency. The centrifugal pump, which is reasonable in structure and high in efficiency, is suitable for counter-current training in a swimming pool, and can be applied in environments with high application requirements.

Description

A kind of swimming pool adverse current training centrifugal pump

Technical field

The utility model relates to a kind of electric pump, and more particularly, it relates to a kind of swimming pool adverse current training centrifugal pump.

Background technique

Swimming pool adverse current training centrifugal pump cooperates the adverse current device to be widely used in large-scale water recreation field, household swimming pond and hydrotherapy leisure place, can realize fixed point swimming, thereby bring up " endless pool ", also is referred to as " running machine in the water ".Adverse current exerciser pump does not have the specific aim design in the market, and flow is less than normal, and efficient is low; Continuous operation under the environment of humidity and ventilation effect difference, so not only the electric pump consumed power is big, and the waste electric energy also causes electric pump the motor burnout phenomenon to occur.

Summary of the invention

At above deficiency, the utility model provides a kind of new adverse current training centrifugal pump of optimal design, and the electric pump design discharge is big, and the efficient height is exclusively used in the training of swimming pool adverse current.Motor Stator Assembly adopts the high-temperature resin filling, reduces electric pump motor because of the Environmental Conditions burnout phenomenon.

The utility model centrifugal pump, it comprises motor part and pump part; The motor part is made up of front end, stator assembly, support, rear end, fan blade, fan housing, rotor assembly, line box etc.; The pump part is made up of mechanical seal, impeller, pump cover, the pump housing, base plate, O shape circle etc.After Motor Stator Assembly is assembled to support, the packing ring epoxy resins.Have advantages such as moisture proof, good heat conductivity, make motor can be under ventilation effect difference and moist environment reliable operation continuously, its operating ambient temperature can reach 70 ℃.

Double shrouded wheel is adopted in the design of electric pump hydraulic performance, and the number of blade is designed to 5 increases the impeller inlet diameter simultaneously to increase exit width, makes inlet diameter reach 70% of outlet diameter.The protruding rank of an annulus of protracting, front shroud of impeller edge form labyrinth seal structure with pump case boss rank, dwindle the distance between front shroud of impeller and the pump case.Can effectively reduce electric pump pressure leakage and disk friction loss, improve whole pump efficiency.

Owing to adopt technique scheme, the adverse current training centrifugal pump that the utility model provides has following beneficial effect:

Motor Stator Assembly adopts the high-temperature resin filling, can adapt to continuous reliable operation under ventilation effect difference and the moist environment, and big flow efficient design is applicable to the training of swimming pool specialty adverse current.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of the utility model adverse current training centrifugal pump, a kind of centrifugal pump shown in the figure, it partly is made up of motor part and pump, and the motor part is made up of support 7, front end 8, line box 9, rotor assembly 10, stator assembly 11, rear end 12, fan blade 13, fan housing 14 etc.; The pump part is made up of pump case 1, impeller 2, pump cover 3, O shape circle 4, mechanical seal 5, base plate 6 etc.;

Fig. 2 is a stator assembly casting resin schematic diagram of the present utility model, will be with out frame vertically to be assemblied on the mould 11c of rear end, is put into special stand 11a and goes up fit on mandrel 11b simultaneously, refills front end mould 11d.Pour into 1/3 stator height high-temperature resin 11e by the perfusion direction, remove special stand 11a, allow mandrel 11b put in the stator assembly endoporus, pour into high-temperature resin once more to design height.

Fig. 3 is that out frame is always schemed behind the filling high-temperature resin of the present utility model, and high-temperature resin 11e should be able to wrap up stator enamelled wire fully.

Fig. 4 is impeller figure of the present utility model.Adopt double shrouded wheel, the number of blade is designed to 5 to increase exit width.Increase impeller inlet diameter 2a, make inlet diameter reach 70% of outlet diameter ￠ D.The front shroud of impeller 2c protruding rank 2b of an annulus that protracts at the edge.

Fig. 5 is pump case figure of the present utility model, and pump case 1 adopts big runner design, with front shroud of impeller 2c registration interface designs one annulus boss 1a.

Fig. 6 is a Fig. 4 impeller and Fig. 5 pump case assembling schematic representation, and front shroud of impeller 2c protract at the edge boss 2b and pump case annulus boss 1a formation labyrinth seal structure dwindle the distance between front shroud of impeller 2c and the pump case.Can effectively reduce electric pump pressure leakage and disk friction loss, improve whole pump efficiency.

Fig. 7 is the M part zoomed-in view of Fig. 6.

The above is concrete enforcement example of the present utility model and the know-why used, do not departing from the equivalence change that principle of the present utility model is done, when the effect that it produced is no more than the content that specification and accompanying drawing contain, all should be in scope of the present utility model, explanation hereby.
