QY series oil-immersed submersible pump

product description
QY series oil-filled small submersible electric pump (hereinafter referred to as electric pump) consists of three parts: water pump, seal and motor. The water pump is located on the upper part of the electric pump and has a centrifugal or axial flow structure; the motor is located at the lower part of the electric pump and is an oil-filled three-phase asynchronous motor; the water pump and the motor are sealed by a built-in integral mechanical seal box, and the fixed stop seals are used " 0""-shaped oil-resistant rubber sealing ring is used for static sealing.
1. QY all-stainless steel oil-filled submersible electric pump is beautiful in appearance and small in size. A unique floating oil bag is installed in the lower part of the pump. The temperature of the electric pump rises and the oil bag is adjusted underwater to prevent temperature rise and burst. Adjust the internal and external pressure to ensure The safety and reliability of pump operation.
2. The mechanical seal adopts fluorine rubber double-end face seal, and the outdoor adopts single-sided mechanical seal, which effectively protects the motor from water ingress and burns.
3. The design of F-class insulated motor and tapered bearing can extend the life of the electric pump.

The main purpose
This series of electric pumps are widely used in rural areas and industrial and mining enterprises because of their wide range of flow and head applications. They are suitable for water supply and drainage in farmland irrigation, garden sprinkler irrigation, underground water lifting, water tower delivery, urban construction water and other occasions.

Conditions of Use
The electric pump should be able to work continuously and normally under the following conditions of use:
1. The working medium is non-corrosive clean water, the volume ratio of particles in the medium is not more than 0.10%, and the particle size is not more than 0.20mm.
2. The temperature of the medium does not exceed 40 degrees Celsius.
3. The electric pump should be used within the range of use near the rated head. And use it completely immersed in water, the diving depth should not exceed 3m, and the deepest should not exceed 5m.
4. The electric pump is more than 0.5m away from the bottom of the water, but it should not fall into the mud.
5. The power frequency is three-phase 50HZ, the voltage is 38OV, and the voltage fluctuation range is 0.9-1.1 times the rated value.
