Bearing seat with external water cooling cavities and for long shaft pump

Abstract

The invention discloses a bearing seat with external water cooling cavities and for a long shaft pump. The bearing seat comprises a bearing seat body and a circulating water supplying device, the bearing seat body comprises a lower machine body and an upper machine body, and the contacting faces of the lower machine body and the upper machine body form a bearing mounting hole through a semi-circular structure. The two sides of the upper machine body are fixedly connected to the lower machine body through bolts, a mounting seat is welded to the bottom of the lower machine body, and the lower water cooling cavity is formed in the position, on the periphery of the bearing mounting hole, in the lower machine body. A water return pipe and an S-shaped pipeline are arranged on the lower machine body, the water return pipe communicates with the lower water cooling cavity, and a water inlet of the S-shaped pipeline is connected with the water return pipe. A water outlet of the S-shaped pipeline is connected with the circulating water supplying device, and the upper water cooling cavity is formed in the position, on the periphery of the bearing mounting hole, in the upper machine body. According to the bearing seat with the external water cooling cavities and for the long shaft pump, the heat dissipation effect of the bearing seat is improved, and the bearing seat with the external water cooling cavities and for the long shaft pump has the advantages of being simple in structure, convenient to use, good in service effect and the like.

Description

technical field [0001] The invention relates to the technical field of bearing housings, in particular to a bearing housing of a long-axis pump with an external water cooling chamber. Background technique [0002] The long-axis pump is a kind of centrifugal pump. From the point of view of the centrifugal pump, it is improved on the performance of the submerged pump. It is a new generation of energy-saving and environment-friendly lift pump developed in China in recent years. The pump can be used for Transport rainwater, scale water, sewage, corrosive industrial wastewater, seawater and other liquids. Widely used in water supply companies, sewage treatment plants, steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, farmland irrigation, flood control and drainage and other projects.

AI Technical Summary

Problems solved by technology

The shaft head at the outlet end is generally equipped with a bearing, but under long-term operation, due to poor internal heat dissipation and frictional heating, it is easy to cause high temperature in the bearing and grease. When the working oil temperature exceeds 60°C, every 8°C increase The service life of the bearing will be halved, and the wear of bearings and parts will be accelerated.

[0003] The existing external water-cooling device cannot realize the recycling of the cooling liquid, the heat on the bearing is not convenient to be quickly transferred to the cooling liquid, and the cooling liquid cannot realize rapid heat dissipation
