Oil collecting device's hydraulic turbine oil pressure unit oil sump tank is leaked in area

The utility model discloses an oil collecting device's hydraulic turbine oil pressure unit oil sump tank is leaked in area, this oil sump tank comprises box, level gauge, filter, combination valve, oil pump electric unit, annular channel -section steel, upper portion joint, upper portion ball valve, hose, intermediate head, collecting box, lower part joint, lower part ball valve and pipeline annex. The steam turbine oil who has certain pressure need be carried to pressure vessel to this oil sump tank, because the fluid of generate pressure mainly concentrates on go back to upper oil tank's oilfilter and combination valve department, so when carrying out the oil sump tank debugging and the work of maintenance, return upper oil tank and often oil leak in various degree can appear, the fluidof leakage can flow into or artificially introduce annular channel -section steel voluntarily, finally gets into the collecting box. This time oil tank structure is simple, on the one hand, avoids the oil leak excessive to th
