Description

Technical Field

[0001] This utility model relates to the field of water pump bearing technology, and in particular to a rust-resistant water pump bearing. Background Technology

[0002] Pump bearings are key components used to support the pump rotor and reduce friction. Their design and material selection directly affect the pump's efficiency and service life.

[0003] However, the existing technology still has shortcomings. In the existing technology, the equipment shaft is inserted into the shaft hole of the inner shaft body. After long-term use, the connection will rust. When replacing it, the entire water pump bearing can only be replaced, which wastes resources. Applying an anti-rust coating to the connection can effectively delay the rusting time and increase the service life, but it still needs to be replaced after a long time.

[0004] Therefore, we propose a rust-resistant water pump bearing to solve this problem. Utility Model Content
