Description

TECHNICAL FIELD

[0001] The utility model relates to chemical equipment technical field especially relates to a kind of for high-temperature-resistant chemical pump bearing heat sink. BACKGROUND

[0002] In the field of chemical production, as a key fluid conveying equipment, chemical pump is widely used in various process flows, and bears the heavy responsibility of efficiently and stably conveying chemical media with different characteristics. The stable operation of chemical pump plays a decisive role in the continuity, safety and production efficiency of the entire chemical production system.

[0003] When working, the bearing of chemical pump, as a key element to support rotating parts and ensure stable rotation of pump shaft, bears huge load. On the one hand, during high-speed rotation of pump shaft, continuous radial force and axial force are generated on the bearing, which causes strong friction between rolling elements and raceway inside the bearing. On the other hand, the medium conveyed by chemical pump often has special properties such as corrosion, high temperature and high pressure, and the working environment is harsh. For example, in the process of conveying some high-temperature medium, heat is conducted to the bearing part through the pump shaft, further increasing the temperature rise of the bearing.

[0004] Due to the above factors, the bearing of chemical pump is prone to heat generation during work. However, the current heat dissipation technology has obvious shortcomings in dealing with the rapid heat dissipation demand of chemical pump bearing. The traditional natural cooling method has low heat dissipation efficiency and cannot dissipate the heat generated by the bearing in time, resulting in continuous temperature rise of the bearing. Even if some chemical pumps use air cooling or water cooling and other auxiliary heat dissipation means, due to the limitations of structure design, heat dissipation medium flow and temperature control, it is still difficult to quickly and effectively reduce the temperature of the bearing.
