MAINTENANCE SYSTEM OF HELICAL TURBINE

摘要

A prefabricated helical turbine is provided to shorten working time and save maintenance cost by assembling a helical turbine and a housing, which form a pair, in plural by using a coupler and a connection member. A prefabricated helical turbine comprises a helical turbine(21) and a housing(11). The helical turbine has a plurality of blades at a rotating shaft(22) thereof to generate continuously rotational force. The housing supports the helical turbine while surrounding the helical turbine. A coupler connects a rotating shaft of the helical turbine with a rotating shaft of another helical turbine. A connection member connects the housing with another housing to support another helical turbine, which is connected with the helical turbine, while surrounding another helical turbine. The number of the helical turbines and the housings, which form a pair, is adjusted according to installation environments of the helical turbines.
