7.5kW Submersible Mixer Pump Denitrification And Nitrogen Removal

Submersible reflux mixer pump Application:
1.In the field of building drainage, diving through the wall pump is often used in the basement, underground parking lot and other places of drainage. The utility model can effectively discharge the stagnant water and prevent the damage of the building structure caused by the water immersion and the damp environment.

2. In terms of engineering aspects, such as modification and expansion of the urban drainage system, rainwater collection and drainage, sewage Sewage Treatment, etc. , the submersible through-the-wall pumps can play an important role. The utility model can realize high-efficient fluid transportation without destroying the original facilities. In the industrial field, some factories of wastewater treatment, cooling circulating water system, process water supply and discharge will also use the link of diving through the wall pump. Especially in the need to cross the wall or obstacles for fluid transport, the advantages are more obvious.

3.In mining, it is used for mine drainage, slurry transportation and other operations to adapt to the complex working environment and special fluid properties in hydraulic engineering, such as reservoir water diversion, river water replenishment and drainage, etc. , submersible through-the-wall pumps can also play their role.

CONDITIONS OF USAGE

Medium temperature: the maximum temperature of a medium (the liquid being transported) can not exceed 400 ° C 1. PH value of the medium: the PH value of the medium should be in the range of 3-12, which is very important to protect the pump body from corrosion 2. Medium density: the density of a medium must be less than 1.2 * 103 kg/M31. Altitude and temperature: submersible return pumps are used at an altitude of no more than 2000m, with ambient temperatures up to 50 degrees Celsius 2. Submersible depth: the maximum submergence depth of a submersible return pump is usually not more than 20m, but in the QJB-W type submersible return pump, the maximum submergence depth is 10m 3. Level requirement: the pump must not be lower than the low level in order to ensure the normal operation of the pump and avoid damage. Stability of voltage and frequency: only when the deviation between the rated voltage and the rated frequency is less than 5% can the motor run normally.
