In the water conservancy works and urban water supply and drainage projects, the accumulation of sewage in front of the gate makes the water flow section smaller, affecting the efficiency of the pumping station and generator sets, and even accidents. To this end, the factory from the cleaning performance and characteristics of pollution equipment, combined with the actual situation of water conservancy and hydropower projects in China, the design and manufacture of hanging type cleaning machine, this machine is technically quite mature, more reasonable structure, strong adaptability, so as to make it play an invaluable role in water conservancy and Hydropower engineering.
