AI Technical Summary
Existing technologies make it difficult to achieve precise installation of water distribution ring pipes in large impulse turbines, leading to problems such as unit vibration and shortened equipment lifespan.
An installation measuring device is used, including a water turbine axis measuring component and a branch pipe axis measuring component. By emitting light through a laser head, combined with horizontal and vertical sliding rods and an angle detector, the precise measurement and calibration of the angle and verticality of the water spray branch pipe can be achieved.
The installation accuracy of the turbine's water distribution ring pipe has been improved, ensuring smooth unit rotation, reducing vibration, and extending equipment life.
