Abstract
The invention discloses a kind of DC brushless miniature circulating pump.It includes pump case (1), rotor (2), stator (3) and impeller (4), rotor (2) is sleeved on armature spindle (5), described armature spindle (5) surface is provided with nanostructured zirconia coating, rotor (2) surface is provided with plastic layer (7), rotor (2) is integrated with impeller (4), is provided with the gap of 0.8 1.0mm between each impeller blade root and impeller sleeve (6).The said structure that the present invention uses, improves the anti-wear performance of armature spindle, it is possible to reduce because the noise produced is strengthened in pump long-play gap；Current can be avoided to produce eddy current at impeller blade root, reduce noise and the workload of pump, thus improve operation stability.
Description
Technical field
The present invention relates to a kind of pump, especially relate to a kind of direct current for balcony wall-hanging solar hot water system
Brushless miniature circulating pump.
Background technology
Circulating pump is a kind of hot water pipeline pump, mainly includes shell, rotor, stator etc., is commonly used for the sun
Energy water heater, to improve the pressure of supply water of hot water.Existing following for balcony wall-hanging solar hot water system
Ring pump, volume ratio is relatively big, is arranged on outside boiler, the most unsightly.Circulating pump rotor many employings metal material
Material is made, and because work is often in severe hot water environment, the time one is long easily by rotten corrosion, and impact uses the longevity
Life.It addition, be blind-mate structure between impeller blade root and the impeller sleeve of existing pump, current
Eddy current can be produced at impeller blade root, increase noise and the workload of pump；Between armature spindle and axle bed
Also due to the abrasion of armature spindle causes gap to be strengthened, thus cause pump operating instability, produce noise.
Summary of the invention
It is an object of the invention to provide a kind of compact conformation, operate stable DC brushless miniature circulating pump.
The required problem solved of the present invention realizes by the following technical solutions: it includes pump case, turns
Son, stator and impeller, rotor is sleeved on armature spindle, and described armature spindle surface is provided with nano zircite
Coating, rotor surface is provided with plastic layer, and rotor is integrated with impeller, each impeller blade root with
The gap of 0.8-1.0mm it is provided with between impeller sleeve.
The said structure that the present invention uses, the nanostructured zirconia coating that armature spindle surface is provided with, improve rotor
The anti-wear performance of axle, it is possible to reduce because the noise produced is strengthened in pump long-play gap；Each impeller blade
It is provided with the gap of 0.8-1.0mm between root and impeller sleeve, current can be avoided to produce at impeller blade root
Raw eddy current, reduces noise and the workload of pump, improves operation stability.
Accompanying drawing explanation
The present invention is described further below in conjunction with the accompanying drawings:
Fig. 1 show the structural representation of the present invention
Fig. 2 show A-A cut-away view in Fig. 1
Fig. 3 show B-B cut-away view in Fig. 1
Detailed description of the invention
From accompanying drawing, this DC brushless miniature circulating pump includes pump case 1, rotor 2, stator 3 and impeller
4, rotor 2 is sleeved on armature spindle 5, and described armature spindle 5 surface is provided with nanostructured zirconia coating, rotor
2 surfaces are provided with plastic layer 7, and rotor 2 is integrated with impeller 4, each impeller blade root and impeller
The gap of 0.8-1.0mm it is provided with between axle sleeve 6.Operationally, hot water is process at impeller 4 for pump, due to
Rotor 2 is integrated with impeller 4, and water will not penetrate into the place of cooperation of rotor 2 from impeller 4, enters one
Step ensure that rotor core does not contacts with water segregation.The nanostructured zirconia coating that armature spindle 5 surface is provided with, can
To reduce between armature spindle and axle bed because the degree of wear run up, life-span are long.Pump case 1 can use work
Engineering plastics is made, and to reduce heat waste, improves usefulness.According to practice, impeller blade root and impeller sleeve 6
Between gap be optimal with 0.8-1.0mm, impeller rotates counterclockwise, use centrifugal principle, will circulation
Water throws away and forms flow velocity, effectively reduces the workload in closed system.
Claims (1)
1. a DC brushless miniature circulating pump, including pump case, rotor, stator and impeller, rotor is set with
On armature spindle, it is characterised in that: described armature spindle surface is provided with nanostructured zirconia coating, rotor surface
Being provided with plastic layer, rotor is integrated with impeller, sets between each impeller blade root and impeller sleeve
Having the gap of 0.8-1.0mm, pump case uses engineering plastics to make.
