Vertical Portable Submersible Sewage Pump With Industrial Axial Flow Propeller
Application:
| 1 | water supply works and power station. |
| 2 | The Axial flow submersible electric pump applies to the condition of low lift head, high flow-rate; while the mixed-flow submersible electric pump is very efficient with high performance of cavitation erosion |
| 3 | It is applicable for the occasion where the water level changes greatly and the requirement to the lift head is high. |
Features:
| 1 | As its operation submerged into water, the electric pump can greatly simplify geotechnical engineering and building structure engineering of pump station, reduce erection space and save 30%-40% construction cost. |
| 2 | Due to the electric motor is combined with the hydraulic pump, the assembly procedure is no longer necessary for lining up axis of electric motor, transmission mechanism and hydraulic pump on site |
| 3 | Convenient operation, and easy to realize remote control and automatic control. |
Model number description:
500: Nominal water outlet caliber of pump (mm)
Z: Axial flow
DB: Electric pump
70: 1/10 of pump specific speed
J: New design, speed down
Operation:
You should write down voltage, current and operation time on every two hours and pay attention to observe the stability of operation of the pump.
Stop pump:
You can press stop button either on situ control line box or on switch cabinet to stop the operation of pump, but you should carefully select position of switch.
Construction:
The rotor has three sets of bearings and two sets of mechanical seals.
The rotation direction of the submersible motor is counterclockwise viewed from the shaft-extension end.
