Sliding bearing bush

Abstract

The invention discloses a sliding bearing bush which comprises a water distribution groove, a fixed boss, cooling water through holes and a bearing bush body, the water distribution groove is connected with the bearing bush body, the fixed boss is connected with the bearing bush body; the cooling water through holes are connected with the bearing bush body, the water distribution groove is arranged at two sides of the bearing bush body, water inlets and water outlets are uniformly distributed in the water distribution groove, eight cooling water through holes are uniformly distributed in the water distribution groove, each cooling water through hole runs through the bearing bush body, and the bearing bush body is a modified engineering plastic part which is treated by modification and processed by a precision machinery. The sliding bearing bush has the advantages as follows: the sliding bearing bush is reasonable in structure, simple, durable, convenient to install and operate, good in working environment, safe, reliable and the like.

Description

technical field [0001] The invention relates to a sliding bearing bush, which is especially suitable for a lower sliding bearing device of a spiral slagging machine for mechanically removing slag from a boiler in a thermal power plant. Background technique [0002] The wet slag removal system of the thermal power plant is equipped with a spiral slag machine at the lower part of the boiler furnace. The high-temperature slag falling from the furnace is cooled by cooling water, and then taken out by the spiral slag machine, crushed by the slag crusher, and then falls into the slag ditch and flows into the slag. pulp pool. [0003] The lower body device of the wet screw slagging machine used in most occasions, that is, the lower bearing bush of the screw slag machine is made of nodular cast iron sleeve or non-ferrous metal sleeve, which is required to be wear-resistant and well sealed to ensure normal operation in slag water immersion , no dripping of slag water, the service l...

AI Technical Summary

Problems solved by technology

[0003] The lower body device of the wet screw slagging machine used in most occasions, that is, the lower bearing bush of the screw slag machine is made of nodular cast iron sleeve or non-ferrous metal sleeve, which is required to be wear-resistant and well sealed to ensure normal operation in slag water immersion , no dripping of slag water, the service life of the lower bearing is not less than 20,000 hours, and it is easy to overhaul and maintain. However, due to the existence of many uncertain factors in production, installation and operation, this situation often becomes a hidden accident point. Cause slag to accumulate, if not repaired in time, it will affect the operation of the unit
