overview
Oil-filled submersible pump is a power drainage and irrigation equipment composed of water pump and three-phase asynchronous motor. The pump is located in the upper part of the pump, which is a centrifugal or axial flow structure, and the motor is located in the lower part of the pump, which is an oil-filled three-phase asynchronous motor. The water pump and the motor are sealed by an internal integral mechanical seal box. Each fixed stop seal is sealed by an "O" shaped oil rubber seal ring. It has reliable waterproof sealing performance. This series of pumps has compact structure, good bearing lubrication conditions, good motor cooling effect, single or multistage centrifugal impeller, radial guide vane structure, small volume, high lift, and wear-resistant double-sided mechanical seal between the pump and the motor. It has the characteristics of small volume, light weight, no need for pump room, no need for irrigation and diversion, and convenient maintenance and management. Widely used in drainage and irrigation, fish pond oxygenation, garden drainage and irrigation, underground water, urban construction, industrial and mining enterprises water.
conditions:
1. The working medium is non-corrosive water, the volume ratio of sand content in the medium is not more than 0.10%, and the particle size is not more than 0.20mm.
2. The medium temperature does not exceed 40 ° C, and the PH value of the medium is between 6.5 and 8.5.
3. The submersible pump should be used within the range of use near the rated head, and be immersed in water, and the diving depth should not exceed 3m and the depth should not exceed 5m.
4. More than 0.5m from the bottom, but do not fall into the mud. Otherwise it will cause an explosion.
5. The power supply frequency of oil-filled submersible pump is three-phase 50Hz, the voltage is 380V, and the voltage fluctuation range is 0.9-1.1 times of the rated value.
