Abstract
The invention discloses a hidden forced circulation pump for a balcony wall-hanging solar hot water system, comprising a pump shell (1), a rotor (2), a stator (3) and an impeller (4), wherein the rotor (2) is sleeved on a rotor shaft (5), a circulation pump (6) is installed inside the end cover of a hot water tank, the surface of the rotor (2) of the circulation pump (6) is provided with a plastic layer (7), and the plastic layer (7) of the rotor and the impeller (4) form an integral structure. By using the structure, the invention avoids the contact between an iron core of the rotor and hot water and can prevent corrosion, thereby prolonging the service life of the pump; moreover, the nanometer zirconia coat on the surface of the rotor shaft improves the wear-resisting property of the rotor shaft and also can reduce the noise generated by increase of clearance due to long-time operation of the pump.
Description
Technical field
The present invention relates to a kind of pump, especially relate to a kind of concealed forced circulation pump that is used for balcony wall-hanging solar hot water system.
Background technique
Recycle pump is a kind of hot water pipeline pump, mainly comprises shell, rotor, stator etc., often is used to solar water heater, to improve the pressure of supply water of hot water.The existing recycle pump that is used for balcony wall-hanging solar hot water system, volume ratio is bigger, is installed in the hot water tank outside, and is very not attractive in appearance.The recycle pump rotor adopts metallic material to make more, often is in abominable hot water environment because of working, and time one length is subjected to rotten corrosion easily, influences working life.In addition, also can cause the gap to be strengthened between rotor shaft and the axle bed owing to the wearing and tearing of rotor shaft, thereby cause noise.
Summary of the invention
The concealed forced circulation pump that is used for balcony wall-hanging solar hot water system that the purpose of this invention is to provide a kind of compact structure, anticorrosive anti-wear.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises pump case, rotor, stator and impeller, rotor is sleeved on the rotor shaft, it is characterized in that recycle pump is installed in the hot water tank end cap, the rotor surface of recycle pump is provided with plastic layer, and rotor plastic layer and impeller are integrated.
Rotor shaft of the present invention surface is provided with nano oxidized zirconium coating.
The said structure that the present invention adopts, rotor surface is provided with the plastic layer with the impeller integrative-structure, has stopped contacting of rotor iron core and hot water, can prevent corrosion phenomena, thus working life of prolongation pump; In addition, the nano oxidized zirconium coating that the rotor shaft surface is provided with has improved the wear-resisting property of rotor shaft, also can reduce to strengthen the noise that produces because of pump long-play gap.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that structural representation of the present invention
Figure 2 shows that A-A cut-away view among Fig. 1
Figure 3 shows that B-B cut-away view among Fig. 1
Figure 4 shows that the scheme of installation of recycle pump on the hot water tank of removing end cap
Embodiment
By accompanying drawing as can be known, this concealed forced circulation pump that is used for balcony wall-hanging solar hot water system comprises pump case 1, rotor 2, stator 3 and impeller 4, rotor 2 is sleeved on the rotor shaft 5, recycle pump 6 is installed in the hot water tank end cap, rotor 2 surfaces of recycle pump 6 are provided with plastic layer 7, and rotor plastic layer 7 is integrated with impeller 4.The plastic layer of rotor surface is isolated rotor iron core and water, plays the effect of anticorrosion-rust prevention.Pump is when operation, and hot water is from the impeller process, because impeller and rotor plastic layer are structure as a whole, water can not infiltrate from the cooperation place of impeller and rotor, has guaranteed that further rotor iron core does not contact with the water isolation.The nano oxidized zirconium coating that rotor shaft of the present invention 5 surfaces are provided with can reduce the degree of wear because of running up between rotor shaft and the axle bed.Pump case 1 can adopt engineering plastics to make, and to reduce heat waste, improves usefulness.
Claims (2)
1. concealed forced circulation pump that is used for balcony wall-hanging solar hot water system, comprise pump case, rotor, stator and impeller, rotor is sleeved on the rotor shaft, it is characterized in that recycle pump is installed in the hot water tank end cap, the rotor surface of recycle pump is provided with plastic layer, and rotor plastic layer and impeller are integrated.
2. a kind of concealed forced circulation pump that is used for balcony wall-hanging solar hot water system according to claim 1 is characterized in that: described rotor shaft surface is provided with nano oxidized zirconium coating.
