Guide bearing structure of hot water circulation pump

Abstract

The invention discloses a guide bearing structure of a hot water circulation pump. The guide bearing structure of the hot water circulation pump adopts the structure as follows: a shaft sleeve is sleeved inside an inner ring of a ceramic sleeve; the shaft sleeve is matched with the inner ring of the ceramic sleeve to form a rotating friction pair; the ceramic sleeve is enwrapped with a protective sleeve; the protective sleeve is installed inside a protective support; the protective support is installed inside a rubber vibration absorber; the rubber vibration absorber is installed inside a guide bearing support; when the ceramic sleeve is stressed by an impact force transferred from the shaft sleeve, the ceramic sleeve transfers the impact force to the protective sleeve, the protective sleeve transfers the impact force to the protective support, and the protective support transfers the impact force to the rubber vibration absorber to cause elastic deformation of the rubber vibration absorber; through the elastic deformation of the rubber vibration absorber, the impact force is balanced, and the ceramic sleeve and the guide bearing are protected; and a once-moulded clamping slot is formed at one end of the ceramic sleeve, a lug boss on a rotation-preventing plate is clamped in the clamping slot, and the rotation-preventing plate is fixed on the guide bearing support, so that the rotation of the ceramic sleeve is prevented and relatively high torsion is borne. The guide bearing structure of the hot water circulation pump has the advantages of simple structure, reliable performance, user convenience, energy conservation, and important significance for studying a safe, reliable and long-life hot water circulation pump.

Description

technical field [0001] The invention relates to a guide bearing structure of a hot water circulating pump, which belongs to the technical field of pumps. Background technique [0002] In industries such as metallurgy, electric power, light textile, petroleum, chemical industry, chemical fertilizer, pharmaceutical, papermaking, environmental protection, rubber, mining heating, waste heat utilization, etc., hot water circulating pumps for transporting heat medium will be used. Since the hot water circulating pump transports high-temperature medium, the temperature of the medium is generally higher than 220°C, and the high-temperature medium will transfer heat to the pump, causing the overall temperature of the pump to rise above 220°C, which also affects the components of the pump. The working environment has a certain impact on the safe operation of the pump. In particular, it has a great influence on the reliable operation of the shaft seal and bearing of the pump.
