It states water level sensor to be used for monitoring water level, when water level attains to a high place or is less than low level, the water level sensor just conveys letter
Number, at this time, it may be necessary to stop water inlet immediately or need to start to intake.
Further, the emulsifier is the emulsifiers of 180 ° of rotations of energy, when the emulsifier is by the oxygenation water body
Impurity obstruction when, the emulsifier rotates 180 ° under the drive of actuator, and the pressure in water inlet line can be by the impurity
Discharge line realizes automatic cleaning function.
The micro-nano bubble aerator of pure oxygen provided by the invention, being pumped using water-cooled silencing supercharging reduces noise, makes noise
Control facilitates repair at 20-30 decibels, reaches 93%-96% using oxygen concentration made from oxygenerator, enables oxygenation water body
Reach water body dissolved oxygen hypersaturated state, oxygenation effect is 4 times of the prior art, and pump integrated set is pressurized with described using charging pump
Charging pump and booster pump are placed in the same shell on the coast, facilitate the care and maintenance of machine, and solve repair by meter
When adjoint electricity consumption it is dangerous, while oxygenerator, charging pump, oxygen increasing pump and emulsifier being all integrated into a shell, more just
Just the maintenance of machine.
