Structure Description

500ZQB-70Axial Flow Pump TypeHQBSubmersible mixed flow pump, consisting of four major components: the inlet bell mouth, impeller part, impeller housing, and guide vane body.

Submersible motors are totally enclosed, dry-type asynchronous motors. The motor housing encapsulates the motor, featuring a static seal at the cable outlet on the upper end of the motor and a rotating seal at the shaft outlet on the lower end cover. Submersible motors possess all the safety and reliability features required for underwater operation. There are monitoring, alarm, and protection devices for seal leakage, winding and bearing temperature rise, which do not interfere with the normal operation of the motor. Early leakage (only an alarm is issued) is detected when the winding temperature exceeds135℃, bearing temperature exceeds90At ℃, the power-off protection is implemented, with all protectors monitored by a dedicated submersible pump protector to ensure safe operation of the submersible pump.

Duane 500ZQB-70Submersible axial flow pump stations have rapidly gained popularity due to their simple civil engineering, low construction costs, ease of maintenance and management, simple installation, ease of automation, high operational reliability, and environmental enhancement.
Main equipment for a submersible pump stationSubmersible pump (also known as a submersible pump)QZType Submersible Axial Flow PumpQHType Submersible Mixed Flow Pump, an integrated electromechanical product that combines an electric motor with an axial flow pump and a mixed flow pump, serving as the updated and replacement for the traditional long shaft axial flow and mixed flow pumps.
Submersible pumps and traditional long shaft pumps essentially maintain consistency in terms of application, water intake and outlet conditions, and characteristic parameters. Advantages include:
Total investment savings in pumping station project30%Above
Construction Cycle Savings40%Above
Installation Time Savings for Engine Assembly95%Above;
Airframe Weight Reduction50%Above;
Eliminate floodwall investment for pump stations.
Low maintenance costs.
No operating noise, easy to operate, and suitable for automated operation.
Low ground building height allows for the elimination of a pump house, and even the construction of a pump station below ground level.
 
In new pump station projects, submersible pumps can be conveniently used as alternatives. They can also be used for upgrading existing pump stations. Submersible axial flow pumps are mainly suitable for the following applications:
◎ Agricultural irrigation and drainage.
◎ Municipal stormwater and light wastewater discharge;
◎ Process water and cooling water for industry
◎ Water Transfer Engineering in Water Conservancy

ZQB Submersible Axial Flow Pump Protection Instructions:

The sensor output signal is received by the submersible pump protector. The protector outputs a switching signal for each output signal, including both switch and analog signals, and displays an alarm flash signal on the protector.
