Problems solved by technology
[0002] Shipbuilding has high technical requirements for the sealing and installation of the stern shaft temperature sensor. The temperature sensor is very susceptible to interference from the external environment, and a small change in its resistance will cause a large deviation in the temperature signal acquisition data.
The problem with the previous installation method is that the lubricating oil will leak from the joint, and the external dregs will enter the stern shaft, which not only pollutes the surrounding environment, but also makes the temperature sensor of the stern shaft interfered by the external environment, which is not suitable for modern Technical requirements for stern shaft sealing system

The sealing device and installation method of the ship stern shaft temperature sensor, the sealing device is a Pulica tube connector, the sealing locking ring and the anti-locking connector are sequentially set on the Pulica tube, and the Pulica tube passes through the Pulica tube. The card tube connector is installed in the sensor connector, and the anti-lock connector is threadedly connected with the tail of the sensor connector. After tightening, the plika tube connector and the sealing locking ring are locked. Mounting holes on the threaded connection. The installation method of the sealing device mainly includes: passing the sensor wire through the installation hole; filling an appropriate amount of sealant at the connection in the sensor connector, and then putting the Pulica tube connector and the sealing locking ring into the sensor connector; Pass the plika tube through the anti-lock connector, seal the locking ring, assemble the plika tube with the plika tube connector; wear the sensor wire, the front part of the sensor connector is threaded with the mounting hole, and the tail Threaded with anti-lock connector. The advantages are good sealing performance and safe and reliable operation of the stern shaft.
Description
technical field [0001] The invention relates to a sealing device and an installation method of a temperature sensor of a stern shaft of a large ship. Background technique [0002] Shipbuilding has high technical requirements for the sealing and installation of the stern shaft temperature sensor. The temperature sensor is very susceptible to interference from the external environment, and a small change in its resistance will cause a large deviation in the data collected by the temperature signal. The problem with the previous installation method is that the lubricating oil will leak from the joint, and the external dregs will enter the stern shaft, which not only pollutes the surrounding environment, but also makes the temperature sensor of the stern shaft interfered by the external environment, which is not suitable for modern Technical requirements for stern shaft sealing system. Contents of the invention [0003] The technical problem to be solved by the present invent...
