I. Production Introduction:
Stainless steel submersible pumps are high-performance, wear-resistent pumps which are produced by international advanced technology. Our products have no pollution to water environment by using advanced oil-filled or water-filled stainless steel motors. Our products are made of quality stainless steel shell, shaft, coupling and the new floating impeller has no axial pressure load to the motor. The water power pattern layout's impeller, raised the efficiency, saved the run cost. Electrical machinery and water pump vertical connection, therefore only need the small installment space. The built-in check valve, is loaded with the prevent returning valve in the pump upper extreme body, prevent water hammer impact.
II. Model Description:
For example: AT 350 QJ 400 -140 /50
AT: Abbreviation of Chinese Aote, enterprise standard
350: minimum well inner diameter
QJ: dives in water fot well using
400: flow capacity
140: head
50: 50-stage impellers connection
III. Application Conditions:
* Rated frequency: 50HZ & 60HZ
* Rated voltage: 380v or 660v three-phase alternating current.
* The pump should be submerged into water and operated in vertical mounting position with the depth of suction head no less than 1 meter in dynamic water level.
* Working medium: corrosive and noncorrosive water.
* Water PH: 6.5-12
* Solid content no more than 0.01% (mass ratio )
* Water temperature: 5°C~25°C
* Well inner diameter: ≥250mm
IV. Unique Feature:
1. The QJ series stainless steel submersible pump is composed of the diving three-phase asynchronous motor and the water pump body. The electric motor with its upside pump body straight association, the electricity engine shaft is equipped with the reliable axis to seal the installment, can prevent in electric motor's refrigerant effectively with the medium exchange which pulls out delivers, guaranteed that the water pump long-term security moves reliably.
2. The water pump is single suction,multistage,vertical,centrifugal pump. The electrical machinery to be filled with water, using the diving asynchronous motor. Electrical machinery and water pump straight associate through barrel shaft coupling.
3. The electric motor winding is the nylon protective covering polyethylene water resistant electromagnetic wire. In the electrical machinery cavity overbrims the pure clear water.
4. Between the pump and the electrical machinery install the axial force carrie.
V. Applications:
The stainless steel submersible pump's application is more widespread than the common centrifugal pump. They are suitable for agricultural irrigation, mining drainage, rainwater recycling system, emergency rescue and disaster relief, urbanwater supply enterprises and goverment institutions water lifting.
