First, the product overview DFZQ, DFHQ series of axial submersible pumps, Francis submersible pump mainly by the pump, impeller, submersible motor and other components. The motor and the pump head are coaxial and form a whole. The motor and the pump are separated by a mechanical seal. The inlet of the cable is sealed and sealed by the incoming line so that the whole motor is in a good sealed state. The whole machine is submerged in the water and runs. The whole internal leakage and temperature protection device, safe and reliable operation. Blade adjustable, flow, head range. Product implementation JB / T10179-2000 "Francis, axial submersible pump" standard. Widely used in farmland hydraulic facilities, urban flood control and water supply, light sewage discharge and water transfer projects. Especially suitable for a large range of flow head lift changes. Second, product characteristics 1, professional and reliable: DFZQ, DFHQ pump series is specially designed for high-volume, low-head applications design, this series is a combination of advanced Zhibeng East Pump technology after years of practice and summary income, is the traditional axis Flow pump, Francis pump the best replacement. Motor, pump into one, dive into the water with traditional units can not match a series of advantages. 2, multi-channel detection, multi-channel protection: oil-water probe, float switch, can be real-time detection and alarm, shutdown, fault signal retention and other functions to make submersible motor safe and reliable. 3, anti-torque device: instantaneous starting moment of the unit starting torque reaction torque will make the whole unit reverse rotation, with the characteristics of the anti-torsion device can easily solve this problem. 4, Durable waterproof cable: Oil-resistant heavy rubber cables, the outlet of a special seal structure to prevent leakage, to ensure long-term reliability, the motor cavity without condensation. 5, safe and reliable: two or more sets of independent mechanical seal, a special friction material placed in series up and down, providing multiple protection, long service life and practical and reliable. 6, investment and easy installation: motors, pumps combined, without on-site complex time-consuming axis consuming work on the installation process, the installation is very easy; the pump running dive into the water, greatly simplifying the pumping station building structural engineering, Reduce the installation area, can save pumping station project total cost 30 ~ 40%. Third, the working conditions Flow: 670 ~ 28000m3 / h Head: 1.0 ~ 20m Medium temperature ≤ +50 ℃ Ambient temperature ≤ +40 ℃ Motor Insulation: Class F Motor Protection: IPX8 water and light sewage
