The operating temperature of the Siemens reducer is high
Thread Content
The coal grinder uses Siemens reducers for cooling; it is cooled by fans as well as by internal circulating water coils. The temperature of its outer wall during operation reaches 74 degrees. Is it normal to use a CKD220 in this case?
It mainly monitors the bearing temperature; as long as it meets the equipment operation requirements, that is sufficient.
With this temperature, the water bearing will not overheat.
This temperature is indeed a bit high, but it remains within an acceptable range at the bearing. What needs to be measured are the temperature and flow rate of the water entering and leaving the cooling water coil, in order to determine whether the temperature difference and flow rate are sufficient to remove the heat. Also, the ambient temperature has indeed been high recently
It is also because the temperature of the cooling fluid being used is high, the temperature of the return water in the circulation system is high, and the pressure is high, all of which affect the cooling process.
