High-temperature pump cooling structure

Abstract

The invention discloses a high-temperature pump cooling structure which comprises a closed cooling mechanism arranged on a pump shaft in a sleeving mode, the closed cooling mechanism is composed of a top cover and a base which are horizontally arranged, and the top cover is of an annular blocky structure; the base is of an annular groove structure with one end open and the other end closed, the open end of the base and one end face of the top cover are in sealed connection and coaxial, and therefore the annular groove is closed to form an annular cooling cavity. A water inlet and a water outlet which are communicated with the annular cooling cavity are formed in the top cover in a bilateral symmetry mode so that liquid in the annular cooling cavity can flow, and heat exchange can be conducted on the pump shaft. Gas heat conduction is changed into forced convection heat exchange, the heat exchange efficiency is effectively improved, and the reliability of parts on the pump shaft is guaranteed.

Description

Technical field [0001] The present invention involves a high -temperature pump cold but technical field, which specifically involves a cooling structure of a high temperature pump. Background technique [0002] High temperature pump is a new type of pump that uses the working principle of permanent magnet couplet to pass torque. When the original motivation drives the external magnetic steel rotor, the internal magnetic steel rotor is used to rotate the internal magnetic steel rotor through the action of the magnetic field, and the internal magnetic steel rotor and the impeller are connected. It is integrated, so as to achieve the purpose of driving the leaf wheel without contact. Because the liquid is closed in a static isolation suit, a high temperature pump is a fully closed and leakless pump type. Therefore The disadvantages of fake, dripping, and leakage. As a result, it is widely used in various fields such as chemical industry, power, metallurgical mines, and nuclear indus...

Problems solved by technology

Since the working temperature of the bearing cavity and mechanical seal is generally required to be below 100°C, if the temperature exceeds this temperature, it needs to be cooled by external means to prevent a large amount of heat from being transferred to the drive end, resulting in mechanical seals, bearings, and motor rotors due to excessive temperature. fail

In order to ensure that the bearing and mechanical seal work normally at a relatively low temperature, the usual method is to use a water cooling system to cool the mechanical seal, but the heat transfer effect for high temperature pumps is not very obvious
