Product Description
The main equipment of submersible pump - Submersible Pump ( referred to as submersible pumps ) , there QZ axial and HW -diving submersible pump, the motor is combined with axial and mixed flow pumps from the machine in one product , traditional long axis axial and mixed flow pumps replacements. New and old customers axial and mixed flow pumps , the new pumping station project with submersible pumps can be easily replaced in the old pumping station renovation project to update submersible pumps , these pumps
Mainly used in the following situations :
1 , irrigation and water conservancy ;
2 , municipal wastewater discharge rain water and mild ;
3 , in industrial process water , cooling water ;
4 , water in the water diversion project .
The Company on behalf of the submersible pump water from 350,500,600,700,800,900,1000,1200,400,1600 totaling ten kinds caliber caliber, flow range 0.12 - 12m3 / s, lift range 2 - 20m; power range 7.5 - 630KW; voltage rating 380V, 660V, 3KV, 6KV, 10KV.
Model Description
350QZ-70G
350 - nominal discharge diameter (mm)
QZ - submersible axial flow pump ; QH representatives submersible mixed flow pump
70 - the number of revolutions of the pump than 1 / 10
G - high speed ; D stands for low speed
Structure Description
QZ submersible mixed flow pump , water pump segment by the bell, impeller parts , guide vane impeller casing and four parts.
Submersible motors are sealed dry asynchronous motors, the motor enclosure closed , the motor cable outlet at the upper end there is static seal loading, the shaft of the motor cover has a rotating seals, submersible motor running with all the safety reliability. Sealing leaks, both coil and bearing temperature monitoring, alarm and protection devices , does not affect the normal operation of the motor early leakage ( only alarm ) . When the coil temperature exceeds 135 ℃, bearing temperature exceeds 90 ℃ , the use of power protection, all protection consists of a submersible pump special protection monitoring to ensure the safe use of submersible pumps.
