Axial Flow Electric Submersible Sewage Pump , 220 Volt Large Submersible Pumps?
Application:
| 1 | The two models ZDB and HDB submersible electric pump can be used in irrigation and drainage of agricultural field |
| 2 | The two models ZDB and HDB can also be used in supply and sewerage water of factory, mine, dock, urban construction, |
| 3 | The conveyance medium is untreated water or lightly polluted water. The highest temperature of the conveyed resolution is 40oC. |
Features:
| 1 | Adopting this type of submersible electric pump is the most through approach for building pump station along the river and lake area where the water level fluctuate greatly, as well as fluctuate the problem of flood prevention of pump; moreover, the major shaft and intermediate shaft are not required any more,and the machine set can operate more steady and reliable. |
| 2 | Submersible electric pump has double and triple mechanical seal and F grand insulation (155oC thermostable ) with protection grand IP68 (IEC). The pump has hydraulic model of nationwide unified design, which has high reliability and has the same performance of the conventional hydraulic pump so that the customer can select the model easily. |
| 3 | Low noise, no high temperature in pump station, improving the operational environment and underground pump station can be built according to the requirement; as a result, the environment scene on the ground can be maintained. |

Material & Structure
Structure of electric submersible pump:
The impeller of ZDB submersible axial-flow pump is semi-adjustable and the inner surface of the enclosure of impeller is spherical. When filling oil into the inner chamber of the guide vane, the oil storage shall not spill from the upper oil way of the oil chamber. There are two symmetrical holes in the sides of the guide vane, one is oil way and the other is vent hole. When filling oil, both holes shall be opened, one for oil filling and the other for air discharging. After the oil is filled in, screw down the two oil plugs. Examine whether the ring seal is damaged, and it must be replaced when damaged. Special anti-winding structure is used between the impeller and guide vane to prevent foreign matters from entering the pump and winding the impeller.
There is a sealed oil chamber inside the guide vane to act as a buffer for the leakage between motor and pump and to lubricate the mechanical seal.
