What are the main process parameters of the power grid?

The main process parameters of the power grid are as follows:

The main technological parameters of 1. grid are grid spacing, grid crossing speed and head loss. The grid spacing is the distance between two adjacent grids. The grid spacing greater than 40mm is a coarse grid, the grid spacing of 20~40mm is a medium grid, and the grid spacing less than 20 ~ 40mm is a fine grid.

2. The speed through the grille refers to the speed at which sewage flows through the grille bars and the grille channels. The velocity passing through the grid should not be too large, otherwise the soft sundries that should be intercepted may be washed away, and the velocity passing through the grid is too small, which may lead to the deposition of sand particles with larger particle size in the sewage in the channel in front of the grid.

3. The head loss of sewage passing through the grille refers to the water level difference before and after the grille, which is related to the speed of sewage passing through the grille. If the head loss on the grid increases, it means that the flow on the grid increases. At this time, it is possible that the water flow above the grille increases, and it is more likely that the grille is partially blocked and needs to be cleaned in time. The decrease of head loss on both sides of the grille indicates that the velocity on both sides of the grille decreases, and measures should be taken to prevent siltation in the river before the grille.
