Abstract

The invention relates to a large-scale circulation pump with a bearing box cooling device, which comprises a pump body, on which a water inlet and a water outlet are arranged, an impeller is installed in the pump body, the impeller is connected with a rotating shaft, and a bearing box is installed on one side of the pump body , the bearing box and the pump body are separated by a pump cover, the rotating shaft passes through the bearing box and the pump cover in turn, and a sealing assembly is provided at the connection between the pump cover and the rotating shaft, and it is characterized in that the two ends of the bearing box are respectively equipped with The front water sealing plate and the rear water sealing plate, the front and rear water sealing plates and the box wall of the bearing box are respectively surrounded to form two independent annular cooling chambers, and the bottoms of the two cooling chambers are connected by cooling water communication pipes. The top surface of the cooling chamber at the front end is provided with a water inlet, the top surface of the cooling chamber at the rear end is provided with a water outlet, and the inner wall of the cooling chamber is provided with a plurality of baffles arranged at intervals.

Description

technical field [0001] The invention relates to a circulation pump, in particular to a large circulation pump with a bearing box cooling device. Background technique [0002] Circulation pump is a multi-purpose chemical pump widely used in electric power, coal chemical industry, environmental protection and other industries for desulfurization, denitrification and wastewater treatment. Large desulfurization pump bearings have large axial and radial loads, and a large amount of heat will be generated in the bearing box. If the heat cannot be effectively dissipated, it will easily cause damage to the bearings and affect the use of the pump. Contents of the invention [0003] The object of the present invention is to provide a large circulation pump with a bearing housing cooling device. [0004] The technical scheme that the present invention takes is: [0005] A large circulation pump with a bearing box cooling device, including a pump body, the pump body is provided with...
