Problems solved by technology

[0002] At present, the bearing box of some steam turbines near the side of the cylinder often has the defect of throwing oil outward. The lubricating oil is thrown out along the turbine rotor journal, and accumulates at the bottom of the cylinder and the surrounding maintenance platform, causing a major fire risk and personnel slipping and falling. Industrial safety Hidden danger
[0003] The defect was mitigated by adjusting and optimizing the installation clearance of the oil deflector ring according to the standard recommended by the steam turbine manufacturer, and reducing the negative pressure of the bearing box, but it has not been able to be eradicated

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 As shown, a detachable oil retaining seal ring, including probe installation sealing hole 1, hoisting hole 2, upper positioning hole 3, upper mounting bolt hole 4, mid-section positioning pin 5, mid-section fastener 6, The upper oil deflector ring 7, the lower oil deflector ring 8, the lower positioning hole 9 and the lower mounting bolt hole 10. Wherein the probe installation sealing hole 1 is a through hole opened at the top of the upper oil deflector ring 7 for installing temperature, vibration and other measuring devices. If not installed, a sealing screw plug can be installed at the end to ensure sealing. There is one hoisting hole 2 on the left and right sides of the probe installation sealing hole 1, which is provided with an internal thread for installing lifting lugs. The upper positioning hole 3 is set on the edge of ...

Abstract

The invention belongs to the technical field of nuclear power plant steam turbine maintenance, and particularly relates to a detachable oil baffle sealing ring, and aims to develop a reliable oil baffle sealing ring. The oil baffle sealing ring has the advantages of being convenient to assemble and disassemble, good in fixing performance, corrosion-resistant, good in sealing performance, high in oil blocking capability and the like. End face sealing and clearance can be effectively guaranteed after installation, and lubricating oil can be prevented from being thrown out along with the shaft. The oil baffle sealing ring is characterized by comprising a probe mounting sealing hole and a hoisting hole, an upper positioning hole, an upper mounting bolt hole and a middle split surface positioning pin, a middle split surface fastener, an upper oil retaining ring, a lower oil retaining ring, a lower positioning hole and a lower mounting bolt hole.

Description

technical field [0001] The invention belongs to the technical field of maintenance of steam turbines in nuclear power plants, and in particular relates to a detachable oil retaining sealing ring. Background technique [0002] At present, the bearing box of some steam turbines near the side of the cylinder often has the defect of throwing oil outward. The lubricating oil is thrown out along the turbine rotor journal, and accumulates at the bottom of the cylinder and the surrounding maintenance platform, causing a major fire risk and personnel slipping and falling. Industrial safety Hidden danger. [0003] The defect can be mitigated by adjusting and optimizing the installation clearance of the oil deflector ring according to the standard suggested by the steam turbine manufacturer, reducing the negative pressure of the bearing box, but it has not been able to be eradicated. Therefore, it is planned to develop a detachable oil retaining seal ring to fundamentally solve the pr...
