Description

Technical Field

[0001] This utility model belongs to the field of steam turbines and relates to a sealing device, specifically a sealing device for quickly adjusting the oil seal of a steam turbine. Background Technology

[0002] A steam turbine is a rotating mechanical device that uses steam as power to convert the thermal energy of steam into mechanical energy. Due to the structural characteristics of steam turbines, the clearance between rotating and stationary parts must be considered during the design process.

[0003] In the bearing housing of a steam turbine, the presence of gaps can lead to the entry of external steam and the leakage of internal lubricating oil. The purpose of the oil-vapor sealing device is to solve the problem of lubricating oil leakage in the turbine bearing housing and to prevent external steam from flowing into the bearing housing and causing lubricating oil emulsification.

[0004] Traditional steam turbine oil-steam seals are fixed designs. During assembly, the appropriate sealing size is achieved by adjusting the clearance between the upper oil seal ring and the main shaft. However, with prolonged operation, rotor deflection may increase, causing accelerated wear of the oil baffles on the oil-steam seal, thus reducing its sealing effectiveness. This necessitates disassembling the oil-steam seal, repairing and fitting it, and then reinstalling it, resulting in significant time and cost waste.

[0005] To solve this problem, there is an urgent need to design a sealing device that can quickly adjust the turbine oil seal. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing device for quickly adjusting the oil seal of a steam turbine, so as to solve the technical problem that the oil-steam sealing device of the steam turbine cannot be adjusted in a timely manner in the existing technology.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A sealing device for quickly adjusting a turbine oil seal is provided, which is used to connect the upper half of an oil baffle ring and the lower half of an oil baffle ring. The upper half of the oil baffle ring and the lower half of the oil baffle ring are respectively provided with a first connecting plate and a second connecting plate. The lower part of the L-shaped adjusting pad is connected to the first connecting plate by a first fastener, and the lower part of the L-shaped adjusting pad is connected to the second connecting plate by a second fastener.

[0009] A horizontally distributed first adjustment component is provided between the upper part of the L-shaped adjustment pad and the first connecting plate, and a vertically distributed second adjustment component is provided between the first connecting plate and the second connecting plate.

[0010] This utility model also includes the following technical features:

[0011] Both the first and second fasteners are screws.

[0012] Both the first and second adjusting components use adjusting screws.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are:

[0014] In practical application, this invention can reduce the workload of operators during factory assembly, lower the difficulty of operation, and save assembly time. On the other hand, when temporary adjustments are needed, adjustments can be made quickly through the first and second adjustment parts, achieving adjustments in four directions without having to return the equipment to the factory for repair. This greatly reduces time costs and solves the technical problem that the oil-gas sealing device of the steam turbine cannot be adjusted in a timely manner in the prior art.
