Belong to physical cleaning, but no matter sprayed using high-pressure water jet or sprayed using water pump, is limited to the huge viscous of underwater fluid
Property, energy is decayed quickly after water-jet goes out, and the physics scouring effect for exchanging heat pipe inner wall is very limited, therefore it only sinks in pipe
Long-pending silt class has expeling effect, completely ineffective for pipe endogenous substance dirt.Third class is with China Mining University and Nanjing
Ke Yuan joint-stock company is representative, and heat exchange tube of condenser inner machine people's the Technolgy of High Pressure Water jet Cleaning, the technology also belongs to physics
Cleaning.But the fatal problem of the technology is: the rigid cleaning sprayer that one is connected to hose must be sent into condenser heat exchange
Pipe, the security risks such as stuck in heat exchange tube of condenser or booster that there are cleaning sprayers.
