Description

Flange oil discharge return device

Technical Field

The utility model relates to the field of maintenance equipment of hydraulic generators, in particular to a flange oil discharge and gear return device.

Background

In the maintenance and dismantling stage of the hydroelectric generating set, each pipeline flange and each equipment flange need to be dismantled, and the medium in the pipeline flanges and the equipment needs to be discharged completely before dismantling, so that the medium leaks when dismantling, and the environmental pollution is avoided. If the cylinder cover of the rotary wheel servomotor needs to be dismantled for overhauling the rotary wheel of a unit in a power plant, a large amount of turbine oil is stored in the cylinder cover of the servomotor, most of accumulated oil in the cylinder cover can be removed through operating the short shaft, but due to the structural problem, 1.8m of accumulated oil exists³Turbine oil can't be discharged through normal channel, need be when runner cylinder cap decomposes to rise synchronous oil extraction, and the way in the past is enclosed the fender in runner cylinder cap flange lower part by taking the film, and after mentioning the cylinder cap, the opening appears in two flange faces, and oil overflows to the film in from the opening between two flanges, and the long-pending oil in reuse oil pump will film is taken away. However, the oil leakage is easily caused by improper control of the oil discharge method, for example, when the opening of the flange is too large and oil overflow is larger than that of oil pumping, the thin film can not slide down to cause oil leakage, the oil overflows out of the thin film to cause oil discharge, and secondly, the thin film is not firmly bound, so that the thin film is easy to fall off and leak oil. In addition, when pumping oil, the pumping pipe head often butts against the film, which easily causes the blocking of pumping oil and even the phenomenon of pumping the film into the pumping pipe. Therefore, on the premise of no effective protection, oil discharge inside the flange medium cannot be effectively controlled, oil leakage forms a normal state, and it is common to clean oil stains on site.
