Power Industry
7/10/2017 5:13:09 PM


The power industry can be divided into thermal power generation, hydropower generation, wind power generation, nuclear power, and bio-power generation.
Power equipment is roughly divided into: generator sets, pumps, valves, power load transfer devices, impeller units, power environmental protection equipment and general equipment.
The mechanical equipment required in each field is also different, but one of the characteristics of power equipment is that the work is uninterrupted, so high requirements are placed on the work of the generator set, such as energy saving, high efficiency, uninterrupted, long life and low maintenance frequency. The repair time is short, and the bearing is an indispensable component of the generator set, and its quality requirements will be higher.
Especially in the special bearings for wind turbines, high reliability is required. This is because the design of this type of bearing is to ensure that the windmill is running for 20 years, and when the fault occurs, the parts are not easy to replace. (When the bearing is used at a distance of tens of meters from the ground).
Therefore, bearing manufacturers require a high degree of computer analysis technology and exquisite skills in materials and heat treatment, and sometimes need to master the test evaluation technology for large bearing materials.
