Supporting roller bearing water feeding detection device and system

Abstract

The invention discloses a supporting roller bearing water feeding detection device and system, and belongs to the technical field of steel rolling equipment maintaining devices. The supporting rollerbearing water feeding detection device comprises an oil feeding pipeline, an oil discharging pipeline and an oil-water separating box; one end of the oil feeding pipeline is connected with a single supporting roller oil return pipeline, and one end of the oil discharging pipeline is connected with an oil tank oil return main pipeline; the oil-water separating box is connected with the oil feedingpipeline and the oil discharging pipeline and located at the lowermost end of the oil feeding pipeline and the lowermost end of the oil discharging pipeline, the bottom of the oil-water separating boxis provided with a water outlet, and the water outlet is provided with a water drain valve and a monitor; and the oil-water separating box is further provided with a water level alarm which is used for controlling the highest level in the oil-water separating box. According to the supporting roller bearing water feeding detection device and system, the technical problem that during steel rollingin the prior art, the situation that water enters a supporting roller cannot be detected can be solved, it can be quickly detected that water enters the supporting roller, the water is drained in time, and accordingly, the technical effect that the supporting roller bearing locking accident is prevented is achieved.

Description

technical field [0001] The invention belongs to the technical field of maintenance devices for steel rolling equipment, and more specifically relates to a water inflow detection device and system for backup roller bearings. Background technique [0002] A hot-rolled strip steel production line generally has multiple finishing mills, and each finishing mill is equipped with an upper and a lower back-up roll, and the back-up roll bearings are lubricated with circulating thin oil. The total number of support rolls is more than ten, and each support roll is equipped with two bearings. Due to the environment of the support rolls (roll cooling water, anti-stripping water has been washing the support rolls) and the wear of the seals, water often occurs in the support roll bearings. Case. The oil supply and lubrication structure of the support roller is that the oil outlet of a thin oil oil supply station is respectively connected to the bearing parts of each support roller to supp...
