[0002] High bearing temperature is a common and harmful fault in rotating equipment, which will reduce the service life of the bearing and increase the maintenance cost. When the temperature rises rapidly and exceeds the standard, it is easy to cause the unit to trip or operate at reduced load unplanned, which has a great impact on economic benefits. Therefore, quickly judging the cause of the fault and taking appropriate measures to solve it is the guarantee for the continuous and safe operation of the equipment.

[0003] Searching the prior art, the publication number CN103062230A discloses a water-cooled bearing seat. A cooling water channel is arranged inside the bearing seat, the cooling water channel is closed by a cover plate, and a water inlet and a water outlet of the cooling water are arranged on the cover plate. Further, after the cooling water channel is covered with the cover plate, the cover plate is welded to the body of the bearing seat.

[0004] In the comparative document, it is manufactured by welding the cover plate to the body of the bearing seat. This structure has cumbersome processes and great processing difficulty during the processing. After processing, it is very easy to have water seepage or leakage at the welding parts, especially at the welding paths of the inner hole and the outer circle and the two side step parts, and the probability of water leakage is very high, which reduces the cooling effect of the bearing installed inside, and even seriously affects the normal use; and after the bearing seat has been used for a certain period, it is difficult to handle during the repair process, and it is difficult to clean out the blockage or debris in the water channel. In the worst case, it cannot be repaired and continued to be used, and new parts have to be made up, which reduces the reuse rate of this type of bearing seat and increases the input cost of the enterprise.
