Description

Technical Field

[0001] The utility model relates to the technical field of turning gears, in particular to a fully automatic turning gear with a new structure. Background Art

[0002] The turning device is to ensure that the turbine can be started at any time after shutdown. After shutdown, the rotor should rotate continuously or regularly to eliminate the thermal bending of the rotor. In addition, the turning device can prevent thermal deformation caused by steam leaking into the turbine due to loose valves. Since the turning device drives the rotor to rotate, the steam in the steam chamber is well stirred to achieve uniform cooling of all parts. When the turbine rotates, the inertia of the rotor and the impact of the blades can be reduced. However, most of the turning devices of steam turbines at home and abroad currently use oil pressure control and pneumatic control, which have certain requirements for oil pressure and air pressure. For renovation projects, it is difficult to meet the on-site requirements. For this reason, we propose a new structure of fully automatic turning device. Utility Model Content
