Abstract

[Problem] To provide a sliding part degradation detection system for a submerged bearing, whereby degradation over time of a submerged bearing can be precisely and easily detected. [Solution] This sliding part degradation detection system (10) for a submerged bearing is characterized by being provided with a sliding part degradation detection tube (40) connected to a bearing housing (24) of a submerged bearing (20) provided with a bearing housing (24) for supporting a rotating shaft in water, and a grease supplying means (30) for connecting to the bearing housing (24) and supplying grease at a predetermined pressure to a gap against the rotating shaft, the sliding part degradation detection tube (40) for releasing to the atmosphere the grease pressure of the grease that has moved through the bearing housing (24).

Description

technical field [0001] The present invention relates to a sliding part deterioration detection system of underwater bearings that detects aging deterioration due to wear of underwater bearings mounted on rotating equipment such as screw pumps, and more particularly relates to water that can accurately and easily detect aging deterioration. Deterioration detection system for the sliding part of the lower bearing. Background technique [0002] There are progressive cavity pumps that draw water from low to high. Figure 4 It is a schematic diagram of the overall structure of a conventional screw pump. As shown in the figure, the screw pump 1 is composed of the following members: an impeller (impeller) 3 provided with blades protruding in a spiral shape that is continuous on the outer surface of the rotating shaft 2, and an upper bearing that supports the upper end side of the rotating shaft 2 on land. 4. An underwater bearing 5 supporting the lower end side of the rotating sha...
