Focusing on stainless steel water pumps
The QY series oil-filled compact submersible pump (hereinafter referred to as the electric pump) consists of three parts: the water pump, seal, and electric motor. The water pump, located at the top of the electric pump, has a centrifugal or axial flow structure; the electric motor, located at the bottom of the electric pump, is an oil-filled three-phase asynchronous motor; the water pump and electric motor are sealed with an internally mounted integral mechanical seal box, and the fixed sealing surfaces are sealed with an "O"-shaped oil-resistant rubber sealing ring for static sealing.
1. The QY all-stainless steel oil-filled submersible pump has a beautiful appearance and small size. A unique floating oil bladder is installed inside the lower part of the pump. As the temperature of the electric pump increases, the oil bladder adjusts its position downward to prevent bursting due to temperature increase, regulating the internal and external pressure to ensure the safety and reliability of the pump operation.
2. The mechanical seal adopts a double-sided fluororubber seal, and a single-sided mechanical seal is used outdoors to effectively protect the motor from water ingress and prevent burnout.
3. The use of Class F insulated motors and conical bearings extends the life of the electric pump.
1. The working medium is a non-corrosive liquid, with the volume ratio of particles in the medium not exceeding 0.10%, and the particle size not greater than 0.20mm.
2. The medium temperature does not exceed 40℃.
3. The PH value of the conveyed medium is 304 (4-10) and 316 (4-13);
4. The electric pump should be used within the operating range near the rated head and should be completely immersed in water for use. The diving depth should not exceed 3m, and the deepest should not exceed 5m.
5. The electric pump is more than 0.5m away from the bottom of the water, but it cannot be trapped in the mud.
6. The power frequency is three-phase 50HZ, and the voltage fluctuation range is 0.9-1.1 times the rated value.
This series of electric pumps has a wide range of applications by flow and head, and is widely used in rural areas, industrial and mining industries, and is suitable for water supply and drainage in farmland drainage and irrigation, garden sprinkler irrigation, underground water lifting, water tower water delivery, urban construction water and other occasions.
