SCREEN CLEANING SYSTEMS:
water intakes are equipped with screen or rack bars to protect against
weeds and debris accompanying flowing waters. This is a common practice
in hydro-power stations and all types of pumping stations. However,
technical problems arise due to accumulation of weeds on screen bars
over time. The resulting throttling would cause a drop in water head.
Hydro-power stations would suffer from noticeable loss of generated
energy and pumping stations would face detrimental cavitation. This
calls for the use of a suitable type of Weed Screen Cleaning Systems
or Trash Raking Systems.
machine is fixed at each water intake. A
chain-driven rake is equipped with tines that are positively engaged
between screen bars to remove accumulating weeds as the rake moves from
bottom to top. The system is operated manually or automatically. Read
traveling system can scan all available pumping station water intakes.
A grab remains open as it descends at the target cleaning location with
its fixed jaw tines positively engaged between screen bars to remove
accumulating weeds. The grab is closed and the system heads for the
discharge area. A Programmable Logic Controller represents the main
control system. An auxiliary traditional system works as a substitute.
