700QZ submersible axial flow pump is YQGN520 submersible motor and 700ZLB type vertical axial flow pump section supporting the machine and pump into an integrated 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.
700QZ submersible axial flow pump is YQGN520 submersible motor and 700ZLB type vertical axial flow pump section supporting the machine and pump into an integrated coaxial drive submersible electric pump. Can be submerged in the water for a long time, with a series of traditional units incomparable advantages:
Technical Advantages：
A As the motor and pump form a single unit, there is no need to carry out labor-consuming and time-consuming motor-transmission mechanism-pump-axis assembly process at the installation site, and it is convenient and quick to install on-site.
B. As submerged in the water operation, can greatly simplify the civil engineering of the pumping station, reduce the installation area, saving 30-40% of the project cost.
C. Low noise, no high temperature in the pumping station, improving the operating environment, and can be built as required, the whole underground pumping station, to maintain the environmental appearance of the ground.
D. Submersible electric pump adopts two mechanical seals, F-class insulation, protection grade IP68 (IEC), the pump section of the national unified design of the hydraulic model, performance and reliability higher than the traditional pumps, to facilitate user selection.
E. Convenient operation, no need to lubricate the rubber bearings of the pump before start-up, easy to control in close proximity or remote control. When building pumping stations along rivers and lakes with large water level rise and fall, adopting 700QZ submersible electric pumps is the most thorough way to solve the problem of motor flood prevention, and it eliminates the long shaft and intermediate bearings between the machine and the pumps, which makes the unit run more stably and reliably.
F. 700QZ submersible axial flow electric pump can be used for farmland drainage and irrigation, industrial and mining enterprises, shipyards, municipal engineering and power station water supply and drainage. The conveying medium is raw water or other liquids with physicochemical properties similar to water, and the maximum permissible temperature of the conveyed liquid is 40K.
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.
