Abstract

The invention discloses a lubricating oil cooling device of a single-stage high-speed centrifugal fan. An evaporation tube is arranged in a heat exchanger tank body and is connected with the heat exchanger tank body through a tube joint, a sealing gasket is arranged between the tube joint and the heat exchanger tank body, and an oil inlet and an oil outlet are arranged on the heat exchanger tank body; a heat radiating tube is arranged in a heat radiator tank body and is connected with the heat radiator tank body through a tube joint, a sealing gasket is arranged between the tube joint and the heat radiator tank body, a heat radiating fin is arranged on the heat radiating tube, and one side of the heat radiating tube is provided with a cooling fan; the heat exchanger tank body and the heat radiator tank body are respectively provided with a connecting flange for mutually connecting the heat exchanger tank body with the heat radiator tank body, and the heat radiating tube, the heat exchanging tube and a compressor form a sealing loop in which a cooling medium is filled. The invention cools lubricating oil by utilizing a refrigeration technique and has the advantages of cyclic utilization of the cooling medium, high cooling efficiency, low sensibility on environmental temperature change and no environmental pollution.

Description

Technical field: [0001] The invention relates to a lubricating oil cooling device for a single-stage high-speed centrifugal fan. Background technique: [0002] Single-stage high-speed centrifugal fans are widely used in sewage treatment, metallurgy, electric power, and petrochemical fields. Due to the high-speed rotation of the transmission gear, the temperature rise of the lubricating oil is high, and a special cooling device is required for cooling. The conventional cooling method is to use air cooling or water cooling. Air cooling has poor adaptability to the climate, and water cooling will cause secondary pollution, and sufficient water source is required. Invention content: [0003] The purpose of the present invention is to provide a single-stage high-speed centrifugal fan lubricating oil cooling device with reasonable structure, strong adaptability to climate and no pollution to the environment. [0004] Technical solution of the present invention is: [0005] A s...
