Abstract

The invention provides a water pump cooling device for a thermal power plant. According to the water pump cooling device for the thermal power plant, cooling water is injected into the pump sleeve, acooling water circulation system is formed by the pump sleeve, a water outlet pipe, a water inlet pipe, a driving box, a heat dissipation box and a heat dissipation water pipe, a driving motor drivesa driving wheel to rotate, and then the meshing effect of first teeth and second teeth is utilized, so that the cooling water sequentially passes through the water outlet pipe, the driving box, the heat dissipation box, the heat dissipation water pipe and the water inlet pipe from the pump sleeve and flows back into the pump sleeve, and cooling water circulation is completed; and in addition, thedriving motor drives a heat dissipation fan to rotate to achieve air cooling and heat dissipation of the water pump. The device can cool the water pump for the thermal power plant, and has the characteristics of long-distance heat dissipation, small cooling water flow, convenience in keeping the temperature of the water pump, easiness in disassembly and assembly and easiness in transportation.

Description

technical field [0001] The invention belongs to the technical field of industrial equipment, in particular to a water pump cooling device for thermal power plants. Background technique [0002] There are two types of heating methods: distributed heating and centralized heating. Distributed heating at the user's site, due to the limitation of the heating scale, only small boilers with low parameters and low thermal efficiency can be used (the thermal efficiency is about 50%). However, heating by thermal power plants forms district heating. Due to the large heating scale, large boilers with high parameters and high efficiency can be used (the thermal efficiency is above 85%), thereby greatly improving energy utilization efficiency and saving fuel. [0003] Thermal power plants need to use water pumps for heat source circulation. The heat source is mainly hot water. Therefore, the entire water pump works at high temperature for a long time without cooling equipment. Excessive...
