Description

Technical Field

[0001] This utility model relates to the field of steam turbine technology, and in particular to a steam turbine bearing condition monitoring device. Background Technology

[0002] In modern industrial production, steam turbines, as a key power source, are widely used in many fields such as power, chemical, and metallurgy. The stable operation of steam turbines plays a crucial role in the efficient and safe operation of the entire production system. As one of the core components of a steam turbine, the operating conditions of its bearings directly affect the turbine's performance and reliability.

[0003] During the operation of a power plant steam turbine, the bearings play a crucial role in supporting the main shaft and ensuring its smooth rotation. However, due to the high-speed rotation of the main shaft on the bearings, the lubricating oil between the bearings and the main shaft generates heat due to friction, causing the bearing temperature to rise continuously. If the bearing temperature cannot be effectively monitored, abnormalities such as excessively high temperatures can lead to bearing burnout, wear and even damage to the turbine's moving and stationary components. This not only results in turbine shutdown and repairs, causing significant economic losses, but also disrupts the continuity of the entire production process and poses potential safety hazards. Existing wired temperature sensors for detecting turbine bearing temperature suffer from problems with the inconvenience of neatly arranged transmission lines. While wireless temperature sensors can be used, the antennas and other equipment at the back end of the sensor can make the back end too heavy, leading to unstable connections. Therefore, there is an urgent need for a steam turbine bearing condition monitoring device. Utility Model Content

[0004] This utility model provides a turbine bearing condition monitoring device to solve the problem in the prior art where the connection between the wireless temperature sensor and the temperature measuring point is unstable because the back end of the wireless temperature sensor is too heavy due to the antenna and other equipment set at the back end of the wireless temperature sensor for wireless transmission.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A turbine bearing condition monitoring device, comprising:

[0007] A wireless temperature sensor, which is connected and installed on the temperature measuring point of the turbine bearing;

[0008] The bracket part includes a connecting plate and a clamp that is movably connected to both ends of the connecting plate, and the other end of the clamp is provided with an installation end;

[0009] The heat insulation baffle includes a heat insulation plate and a mounting rod disposed on the side of the heat insulation plate for connection with the bracket. The heat insulation plate is inserted into the probe end of the wireless temperature sensor.

[0010] In one specific embodiment, the clamp includes a right-angle rod and a crossbar disposed at the upper end of the right-angle rod, the right-angle rod and the crossbar being integrally formed to form the clamp as a whole.

[0011] In one specific implementation, the lower end of the right-angle rod is provided with a sleeve for connecting with the connecting tray, and the lower end of the sleeve is threaded with a fixing bolt.

[0012] In one specific implementation, the upper end of the right-angle rod is provided with a connecting slot for connecting the mounting rod.

[0013] In one specific implementation, the bracket portion is a component made of engineering plastic.

[0014] In one specific implementation, the heat insulation board is a component made of polyurethane foam material, and the heat insulation board has a recess for insertion into the probe end of a wireless temperature sensor.

[0015] In one specific implementation, the mounting rod has an L-shaped structure. One end of the mounting rod is connected to the side of the heat insulation plate, and the other end is provided with a stop and a threaded post fixedly disposed at the lower end of the stop. The threaded post is inserted into the connecting groove, and a nut is threaded onto the threaded post.

[0016] In one specific implementation, the diameter of the stop head is greater than the width of the connecting groove, and the diameter of the threaded post is smaller than the width of the connecting groove.

[0017] The beneficial effects of this utility model are:

[0018] The clamp is movably connected to both ends of the connecting tray. After the wireless temperature sensor is connected and installed on the temperature measuring point of the turbine bearing, the tray is connected to the turbine through the mounting end set at the other end of the clamp. The connecting tray supports the wireless temperature sensor, which can effectively prevent the connection between the wireless temperature sensor and the temperature measuring point from being unstable due to the excessive weight of the rear end of the wireless temperature sensor. At the same time, the heat insulation plate set in the heat insulation baffle is inserted into the probe end of the wireless temperature sensor, separating the outside of the turbine from the rear end of the wireless temperature sensor, which can reduce the impact of heat on the rear end equipment of the wireless temperature sensor.
