Abstract
The utility model provides an improved circulating pump, and the circulating pump is composed of a housing of a motor, a rotor, a rotating shaft, a bearing, a stator, a sealing ring, a pump body, and an impeller. The utility model is characterized in that the rotating shaft and the bearing are made of ceramics; a rotor sleeve made of stainless steel is arranged on the rotor; a rotor cylinder is arranged on the outside of the bearing and the rotor; the rotor cylinder and the housing of the motor form a sealing cavity, and the stator is sealed in the sealing cavity by the sealing cavity; the sealing cavity is filled with insulation material. After the improvement, the utility model has the advantages of boiling water corrosion resistance, high durability, safe operation, small power loss, etc. The utility model is suitable to be used for pressurizing of boilers or water supply pipelines of solar water heaters.
Description
Affiliated technical field
The utility model relates to the pump class, particularly a kind of recycle pump.
Background technique
Recycle pump is a kind of hot water pipeline pump, is usually used in boiler, solar water heater, to improve the pressure of supply water of hot water.Because the operating time is long, be subjected to the boiling water temperatures involved again, its working environment is more abominable, and existing recycle pump is still along in the design of suction booster, do not take corresponding effective measures, therefore its water-proof performance is poor, and radiating condition is bad, cause existing recycle pump exist always dangerous, deficiency such as be not durable.
Summary of the invention
The purpose of this utility model is to solve the problem that existing recycle pump exists, and a kind of recycle pump with characteristics such as safe, reliable, durable is provided.
Task of the present utility model realizes by this way: this recycle pump is made up of motor housing, rotor, rotating shaft, bearing, stator, seal ring, the pump housing and impeller, it is characterized in that rotating shaft and bearing make with pottery, on rotor, be provided with a rotor cover made from stainless steel, be provided with a rotor drum at bearing and rotor outside, this rotor drum and motor housing constitute one with the Seal cage of seal stator in it, and are perfused with insulating material in Seal cage.
The purpose of this utility model also can be taked to realize for following measure:
The stupalith of making rotating shaft and bearing is aluminium sesquioxide, silica.
Described sealing material is epoxy resin, polyamine ester.
After above-mentioned improvement, can be achieved as follows useful effect:, do not have the problem that is subjected to aqueous corrosion, and improved wear resistance greatly because rotating shaft and bearing adopt pottery to make; On rotor, be provided with a stainless steel sleeve, can protect rotor iron core not produce corrosion; Stator is arranged at prevents in the Seal cage that sealing enters in the stator, has improved insulating properties.In addition, in Seal cage, be perfused with sealing material, can improve its thermal diffusivity, the reinforced insulation protection.Therefore, the defective that the utility model can solve existing recycle pump effectively has anticorrosion, durable, advantage such as safe and reliable and power loss is little.
Description of drawings
Fig. 1 is the sectional view of a kind of concrete structure of the utility model.
Embodiment
With reference to Fig. 1, the pump housing 7 of the motor housing 1 of this recycle pump, rotor 2, rotating shaft 3, bearing 4, stator 5, seal ring 6 and water pump is identical with the structure of impeller 8 with annexation and prior art basically, its improvements are that rotating shaft 3 and bearing 4 adopt the aluminium sesquioxide pottery to make, and are provided with the rotor cover made from stainless steel 9 on rotor 2.Be provided with a rotor drum 10 in the outside of bearing 4 and rotor 2, this rotor drum 10 is isolated rotor 2 and stator 5, and stator 5 is placed in it by the inner chamber 11 that its bottom surface and motor housing 1 are connected to form a sealing, the packing ring epoxy resins is made insulating material 12 in inner chamber 11, and the stainless steel integrated stretching of these rotor drum 10 usefulness forms just can.Impeller 8 is installed on the underpart of rotating shaft 3.The underrun seal ring 6 and the compressing tablet 13 of motor housing 1 and rotor drum 10 are installed on the pump housing 7.
Claims (3)
