Title: STEAM TURBINE BARRING ROCKER SHAFT SEALING APPARATUS
Abstract:
A steam turbine barring crank shaft sealing apparatus, comprising a crank shaft (1), a turbine base (4), shaft holes (4.1, 4.2) on two sides of the turbine base, a hand crank mounting base (3), and a stroke controller mounting base (2), the crank shaft (1) being mounted in the turbine base shaft holes (4.1, 4.2), the hand crank mounting base (3) and the stroke controller mounting base (2) respectively being arranged at the two ends of the crank shaft (1), a hand crank being arranged on the hand crank mounting base (3), rotation of the hand crank rotating the crank shaft (1) to implement electric-powered barring, sealing members also being arranged at positions corresponding to the turbine base shaft holes (4.1, 4.2), and the sealing members having a sealing effect and preventing lubricant from leaking from shaft base gaps. The advantages thereof are preventing lubricant waste, ensuring environmental sanitation, and also preventing the occurrence of safety hazards.
