Embodiment

[0024] As shown in the figure, the circulating pump rubber bearing, the bearing body is designed as a split structure. The bearing body is composed of 6-petal strip bearings. The 6-petal strip bearings are evenly arranged. Each strip bearing is installed by fixing bolts and positioning pins. On the corresponding bearing body, each of the described bearings adopts a metal base lining rubber structure. Each bearing is provided with a water passage groove along the axial direction. The shape of the water passing groove is an arc-shaped asymmetric groove.

[0025] The base material of the present invention is 316L, which belongs to austenitic stainless steel, which has good corrosion resistance to various inorganic acids, organic acids, alkalis, and salts, and is a material often selected for seawater as the medium;

[0026] The rubber material is nitrile rubber, which has good chemical resistance, high tensile strength, and excellent physical and processing properties.

[0027] Nitril...

Abstract

The invention relates to a rubber bearing for a circulating pump. A bearing body of the rubber bearing is designed to be of a sectioned structure. The bearing body is an integrated body formed by combining multiple sections of strip-shaped bearings. Each section of strip-shaped bearing is mounted on the corresponding portion of the bearing body. Each section of bearing is of a rubber-lined metal matrix structure. According to the rubber bearing for the circulating pump, by the adoption of the whole structure, the comprehensive performance of wear-corrosion resistance, shock resistance and impact resistance of the rubber bearing is improved greatly, and the service life of the rubber bearing is prolonged.

Description

Technical field [0001] The invention relates to a bearing, in particular to a rubber bearing of a circulating pump. Background technique [0002] The circulating cooling water system is an important equipment in the conventional island of a nuclear power plant. Its function is to extract seawater to provide sufficient cooling water to the steam turbine condenser. It will cool the steam completed from the low pressure cylinder of the steam turbine into condensed water and participate in the steam-water cycle again. Maintain the continuous operation of the unit. [0003] The circulating water pumps used in nuclear power plants are all vertical pumps. The axial force of the pump rotor is borne by the motor, and the radial force of the rotor is borne by the circulating pump guide bearing. Guide bearings are generally divided into two types, one is rubber guide bearings, and the other is babbitt alloy oil lubricated guide bearings. Rubber guide bearings can work in sea water or water ...
