Filtering and pressure stabilizing system for main shaft sealing water of hydropower station unit

Abstract

The invention discloses a filtering and pressure stabilizing system for main shaft sealing water of a hydropower station unit. The main shaft sealing water is conveyed through a main shaft sealing water main pipe, the filtering and pressure stabilizing system comprises a pressure stabilizing device and a filtering device, and the pressure stabilizing device is arranged on the main shaft sealing water main pipe and used for adjusting the water pressure value of main shaft sealing water conveyed through the main shaft sealing water main pipe, and the filtering device is arranged on the main shaft sealing water main pipe and used for filtering impurities of the main shaft sealing water conveyed through the main shaft sealing water main pipe. According to the filtering and pressure stabilizingsystem for the main shaft sealing water of the hydropower station unit, the pressure stabilizing device and the filtering device are applied to the main shaft sealing water main pipe, the previous mode that main shaft sealing water is conveyed only through the main shaft sealing water main pipe is replaced, the pressure of the main shaft sealing water is stabilized, and the impurities in the mainshaft sealing water are filtered out.

Description

Technical field [0001] The invention relates to the technical field of main shaft sealing of a hydropower station unit, in particular to a filtering and stabilizing system for main shaft sealing water of a hydropower station unit. Background technique [0002] See figure 1 , figure 2 Shown: When the water turbine generator set is running, the water turbine runner anti-leak ring will cause water leakage, and this leakage will overflow along the gap between the main shaft 1 and the fixed part 2 (ie water seal seat), so the water turbine generator sets are all set Leak-proof sealing device (referred to as spindle seal). In order to solve this problem, the main shaft sealing device is often installed. When the hydro-generator unit is running, the sealing water is introduced to the main shaft sealing device through the sealing water inlet 6, and the sealing water lifts the main shaft sealing ring 3 ( figure 1 The middle is vertical upwards), close to the rotating ring 4, thereby redu...

AI Technical Summary

Problems solved by technology

In large workshops and other places, there are hundreds or thousands of devices that require the sealing water of the main shaft sealing water pipe, and rely on the main shaft sealing water to cooperate to achieve sealing. Water will sharply increase the cost of these devices, resulting in frequent failure of the spindle 1 seal and frequent replacement of the leak-proof sealing device
