Chain-Type Systems

Monorail-Type Systems

WEED SCREEN CLEANING SYSTEMS:

Open-Source 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.

CHAIN-TYPE SYSTEMS:

A 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 More.

MONORAIL-TYPE SYSTEMS:

A 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. Read More.
