High-temperature-resistant mechanical sealing shaft

Abstract

The invention provides a high-temperature-resistant mechanical sealing shaft, and relates to the field of mechanical sealing shafts. The high-temperature-resistant mechanical sealing shaft comprises amechanical sealing shaft body and a shaft sleeve, wherein the mechanical sealing shaft body comprises a static seat and a movable seat; and the surface of the static seat is fixedly connected with afirst protection seat, the top of the inner wall of the first protection seat is fixedly connected with a first anti-corrosion layer, the bottom of the first anti-corrosion layer is fixedly connectedwith a first metal reflection film, and the bottom of the first metal reflection film is fixedly connected with the bottom of the inner wall of the first protection seat, and a static ring is fixedlyconnected to one side of the static seat. According to the high-temperature-resistant mechanical sealing shaft, heat-conducting carbon fibers is arranged inside a filling cavity, heat can be absorbedand conducted due to the high thermal conductivity of the heat-conducting carbon fibers, the heat absorbed by the heat conduction carbon fibers is dissipated and eliminated through a heat dissipationwire, the heat can be transmitted to cooling fins through a heat conduction connecting block, heat dissipation and elimination is carried out through the heat dissipation wire and the cooling fins atthe same time, and the effect is better.

Description

technical field [0001] The invention relates to the technical field of mechanical seal shafts, in particular to a high temperature resistant mechanical seal shaft. Background technique [0002] A mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal to keep fit and slide relative to each other. It is a shaft seal device for rotating machinery. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the medium in the equipment leaks out through this gap. If the pressure inside the equipment is lower than atmospheric pressure, the air leaks into the equipment, so there...
