Abstract
The utility model discloses a balcony wall mounted water tank with a concealed forced circulating pump, which comprises an inner sleeve (1) arranged on the periphery of the water tank and a medium circulation pipe (8) disposed on the inner sleeve (1). The forced circulating pump (6) is arranged on the medium circulation pipe (8), a hot water outlet pipe (3) is arranged in the middle of the water tank, the position of a pipe opening of the hot water outlet pipe (3) is lower than the height of the water tank, the forced circulating pump (6) is mounted inside an end cover of the hot water tank in a concealed manner, a plastic layer (7) is arranged on the surface of a rotor (2) of the circulating pump, and the rotor plastic layer (7) and an impeller (4) are in integrated structure. By adopting the structure, partial vacuum remained at the top portion position of the water tank leaves space for expansion of water level when the water temperature rises, and then the water tank avoids hidden safety hazards. Besides, the plastic layer in integrated structure with the impeller is disposed on the surface of the rotor and capable of preventing corrosion phenomena, and then the service life of the pump is prolonged.
Description
Technical field
The utility model relates to a kind of balcony wall-mounted water tank, especially relates to a kind of balcony wall-mounted water tank with concealed forced circulation pump.
Background technology
Along with popularizing of solar water heater, the user is more and more higher to the functional requirement of water heater.The solar water container of prior art, its structure generally comprises shell, water inlet pipe and water outlet pipe, heat exchanger and inner bag.This water tank also can carry out medium circulation by the heat exchanger in the water tank except adopting electrical heating, thereby improves the heat exchange effect of water tank.At present, the heat exchanger that has adopts the version of inner bag chuck, and medium circulates between the inner bag chuck.Circulating pump is a kind of hot water pipeline pump, often is used to the solar water heater medium circulation, and to improve the pressure of supply water of hot water, feed-tank brings potential safety hazard but the water temperature rising is expanded also.The existing circulating pump that is used for balcony wall-hanging solar hot water system, volume ratio is bigger, is installed in the boiler outside, and is very not attractive in appearance.The circulating pump rotor adopts metal 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 service life.In addition, also can cause the gap to be strengthened between armature spindle and the axle bed owing to the wearing and tearing of armature spindle, thereby cause noise.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, the safe and reliable balcony wall-mounted water tank with concealed forced circulation pump.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises the inner bag chuck of water tank periphery, and be located at medium circulation pipeline on the inner bag chuck, the medium circulation pipeline is provided with forced circulation pump, described water tank centre position is provided with a hot water outlet pipe, and hot water outlet pipe's nozzle position is lower than the water tank height; Described forced circulation pump is concealed to be installed in the boiler end cap, and the rotor surface of circulating pump is provided with plastic layer, and rotor plastic layer and impeller are integrated, and the armature spindle surface of circulating pump is provided with nano oxidized zirconium coating.
The said structure that the utility model adopts, parital vacuum can be left in the tank top position, and the space has been reserved in the expansion of water level when raising for water temperature, has stopped potential safety hazard; Rotor surface is provided with the plastic layer with the impeller integrative-structure, has stopped contacting of rotor core and hot water, can prevent corrosion phenomena, thereby prolong the service life of pump; In addition, the nano oxidized zirconium coating that the armature spindle surface is provided with has improved the anti-wear performance of armature spindle, also can reduce to strengthen the noise that produces because of pump long-play gap.

The specific embodiment
By accompanying drawing as can be known, this balcony wall-mounted water tank with concealed forced circulation pump comprises the inner bag chuck 1 of water tank periphery, and be located at medium circulation pipeline 8 on the inner bag chuck 1, medium circulation pipeline 8 is provided with forced circulation pump 6, described water tank centre position is provided with a hot water outlet pipe 3, and hot water outlet pipe's 3 nozzle positions are lower than the water tank height; Cold water enters water tank from cold water inlet, when water level reaches hot water outlet pipe's position owing to water temperature raises, cold water will overflow from hot water outlet, thereby local vacuum will appear in the tip position of water tank, and the space has been reserved in the expansion of water level when raising for water temperature.Described forced circulation pump 6 concealed being installed in the boiler end cap, rotor 2 surfaces of circulating pump are provided with plastic layer 7, and rotor plastic layer 7 is integrated with impeller 4.The plastic layer 7 on rotor 2 surfaces is isolated rotor core and water, plays the effect of anticorrosion-rust prevention.Pump is when moving, and hot water is from impeller 4 processes, because impeller 4 is structure as a whole with rotor plastic layer 7, water can not infiltrate from the impeller 4 and the cooperation place of rotor 2, has guaranteed that further rotor core does not contact with the water isolation.Armature spindle 5 surfaces of circulating pump described in the utility model are provided with nano oxidized zirconium coating, can reduce the degree of wear because of running up between armature spindle 5 and the axle bed.The pump case of forced circulation pump can adopt engineering plastics to make, and to reduce heat waste, improves usefulness.
