800QZ-125 submersible axial flow electric pump is YQGN520 series submersible motor and 800ZLB type vertical axial flow pump pump section supporting the machine and pump into one coaxial drive submersible electric pump. The whole pump adopts the company's professional self-developed electromagnetic computer optimization design and calculation program：
Fully waterproof insulation technology for electric motors/Submersible motor temperature rise technology/Leak-proofing technology for motor seals and cable seals/First mechanical seal decompression and three-layer mechanical seal structure/Dynamic and static insulation (leakage current) online monitoring, intelligent protection and control technology, etc.
800QZ-125 submersible axial flow electric pump is YQGN520 series submersible motor and 800ZLB type vertical axial flow pump pump section supporting the machine and pump into one coaxial drive submersible electric pump. It can be submerged in the water for a long time, and has a series of incomparable advantages of traditional units:
Technical Advantages：
1.1 As the motor and pump form a single unit, there is no need to carry out the time-consuming and labor-consuming motor-transmission mechanism-pump-to-axis assembly process on site;
1.2. Due to the submerged operation, it can greatly simplify the civil engineering of the pumping station, reduce the installation area and save 30%-40% of the project cost;
1.3. Electric pump submersible operation, above the surface of the water is almost no running noise, electric pump is water cooling, does not produce environmental high temperature, the duty officer on duty in the control room, the working environment is comfortable;
1.4 The electric pump has no oil, water, gas auxiliary equipment, easy to run;
1.5. Submersible electric pump adopts three mechanical seals to prevent the motor and the oil chamber from water ingress, F-class insulation, protection grade IP68 (IEC), the pump section adopts the national unified design of the excellent hydraulic model, the performance and reliability is higher than that of traditional pumps, which is convenient for the user to select the type.
The conveying medium is raw water or other liquids with physicochemical properties similar to water, and the maximum permissible temperature rise of the conveyed liquid is 40 K.
Product usage：
QZ type axial flow submersible electric pumps and QH type mixed flow submersible electric pumps are suitable for water conservancy flood control and drainage, agricultural irrigation and drainage, municipal water supply and drainage, sewage treatment, dock lifting and lowering of water, water supply and drainage of power stations, regional water diversion and transfer, aquaculture, ecological environment, such as water system management and other fields. Axial flow submersible electric pump is suitable for low head, large flow occasions.
