FIELD: manufacturing technology.
SUBSTANCE: invention relates to the working fluids sewerage systems for, in particular to sewage, industrial and waste waters reception systems in their conservation, pumping and processing facilities, it can be used in the input units manufacturing, which are resistant to electrochemical corrosion and cavitation erosion, for example, in the ship's wastewater tanks. Disclosed is the working fluid input unit comprising the mounted on supporting structure smoothly curved outlet branch pipe with nozzle, the outlet branch pipe with a nozzle is vertically directed into the horizontally arranged baffle plate. Outlet branch pipe cavity, the nozzle and the baffle plate are covered with epoxy resin or polyurethane, or outlet branch pipe, the nozzle are made of polypropylene, and the baffle plate is covered with polypropylene.
EFFECT: technical result consists in the working fluid colloidal sediments washout improvement, increase in the working fluid input unit resistance to electrochemical corrosion and cavitation erosion.
