Abstract

A wear-resistant self-heating guide bearing for a BCP pump, comprising a guide bearing body, a pump shaft, a wear-resistant layer, a water inlet, and a water outlet; the pump shaft is coaxially arranged in the guide bearing body; the pump shaft and The wear-resistant layer is provided between the guide bearing body, and the components of the wear-resistant layer are C; Si; Mn; Cr; Mo; V; W; B; the rest is Fe; the inner wall of the guide bearing body and The water inlet is provided between the pump shafts; two water outlets are also provided between the inner wall of the guide bearing body and the pump shaft. The beneficial effects of the present invention are: (1) The water flowing into the water inlet forms a water film between the guide bearing body and the pump shaft, which plays the role of lubrication and wear resistance; (2) The water flowing into the water inlet takes away the pump The heat generated by the friction between the shaft and the guide bearing body flows out from the water outlet to achieve the purpose of self-dissipation; (3) The melting point of B and Si in the wear-resistant layer is between 950 ° C and 1150 ° C, which has good wear resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the field of furnace water pumps, in particular to a wear-resistant self-heating conduction bearing for a BCP pump. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The guide bearing in the BCP pump (ie boiler water circulating pump) is prone to severe wear due to long-term operation, and the heat generated by high-speed friction between the guide bearing and the pump shaft is not dissipated in time, which will affect the operation of the entire bearing. Contents of the invention [0003] The object of the present invention is to provide a wear-resistant self-radiating conduction bearing for BCP pumps in order to overcome the deficiencies in the prior art. [0004] In order to solve the problems of the technologies described above...
