Abstract

The invention discloses a high-temperature resistant pump comprising a pump body, an impeller, a shaft sleeve, a pump shaft and a pump cover, wherein the pump body is U shaped and is installed on the shaft sleeve; the shaft sleeve and the impeller are arranged on the pump shaft; the impeller is positioned in the groove of the pump body; the pump cover is connected to the front end of the pump body; the pump shaft is connected with the main shaft of a motor; a shaft cooling sleeve and a fan are arranged between the pump body and the motor in sequence; the shaft cooling sleeve is connected with the pump body; the middle part of the shaft cooling sleeve is fully cylindrical, and round cooling fins are evenly distributed at the periphery of the shaft cooling sleeve; a shell is arranged outside the shaft cooling sleeve; two ends of the shell are respectively connected with the motor and the pump body; and a mechanical sealing element is arranged between the shaft cooling sleeve and the fan and on the shaft cooling sleeve. The high temperature-resistant pump has simple structure, low cost and long service life and is simple to manufacture and maintain.

Description

Technical field [0001] The invention relates to the field of pump equipment, in particular to a high temperature resistant pump. Background technique [0002] Existing high temperature resistant magnetic pumps, the maximum temperature resistance is limited by the heat resistance properties of the magnet (for example, the maximum temperature resistance of Samarium Cobalt 2:17 is 350℃), and the magnetism will gradually decrease with the extension of high temperature use time, and finally the magnetic pump Lost the normal work; when the heat transfer oil (water) pump is connected to the motor, the heat energy of the pump is too high due to the heat conduction to the motor and the motor shaft, and the temperature of the motor is too high, and the temperature of the motor is too high , Including the bearing temperature is too high, resulting in the failure to design an ultra-high temperature pump. The high temperature resistance of the mechanical seal material (fluorine rubber) is no...
