Product details

    Submerged self-priming aerator, stainless steel self-priming aerator, submerged aerator QSB2.2

    Submerged self-priming aerator 2.2 typeUsage conditions:1Altitude, not exceeding2000Rice;2Surrounding air temperature -5~40℃; 3、The relative humidity of the air is not greater than90%(In)25Below ℃);4No severe vibration or impact, and vertical inclination not exceeding5Places with a temperature of ℃; 5. A place with no explosion hazard and no gas or conductive dust in the medium that can corrode metals and damage insulation; 6. A place free from rain, snow, and water vapor invasion.

    Structure and principle: The control box consists of circuit breakers, AC contactors, and thermal relays.

    haveThere are two working modes: manual and automatic. And signals such as operation and overload are remotely transmitted to the PLC.

    Submerged self-priming aerator QSB2.2The adhesive bubbles of type floating in water are usually caused by the buoyancy force of gravity and other external forces. Newton's two laws can be derived from the velocity of gas particles, and the floating velocity depends on the density difference between water and gas particles, the diameter (or characteristic diameter) of gas particles, and the temperature and flow rate pattern of water. If the bubbles are larger within the band, the lower the density of gas particles, the larger their characteristic diameter.

    Practice has proven that the particle size of air flocs causes constant changes in resistance, as well as changes in the formation of bubbles and floating rates in the air force. The detailed floating speed can be determined based on experiments. Based on the determination of the rising speed, it can be concluded that the appearance of the air bearing load. The floating exchange rate depends on the demand for water.

      


    Submerged aerator QSB2.2material

    The base and casing of the aeration dedicated pump are made of HT250 cast iron, which has certain corrosion resistance and can withstand the impact of certain loads.

    The motor shaft of the dedicated aeration pump is made of 2cr13 corrosion-resistant material, and measures have been taken to eliminate stress concentration in the structural design.

    The mechanical seals of the dedicated aeration pumps can be made of silicon carbide/silicon carbide, tungsten carbide/tungsten carbide, or silicon carbide/tungsten carbide materials according to the pumping medium. The design service life of the mechanical seals is over 12000 hours.

    The bearings of the dedicated aeration pump are imported NSK bearings, and their cumulative design operating life can ensure over 40000 hours.

    The static seal of the 5 submersible jet aerator adopts Dingqing-70 O-ring.

    All fasteners of the 6 submersible jet aerator are made of stainless steel.

    The material of the intake pipe of the 7 submersible jet aerator is galvanized.

    The nozzle material is cast iron.

    The submersible aerator using three-phase power supply should be checked for rotation direction after initial start-up or each reinstallation. Incorrect rotation direction can reduce efficiency and damage the water pump.

    The inspection method is: Before the final installation of the submersible aerator, look up at the suction port of the submersible aerator from the bottom and rotate the impeller counterclockwise. If several submersible aerators are connected to a controller, each aerator must be inspected separately. If the rotation direction is incorrect, the position of any two of the three-phase wires on the controller can be exchanged to change the rotation direction
