Structural characteristics
ZDG type high efficiency and energy saving self-balancing multi-stage pump has reformed and innovated the traditional structure form, cancelled the axial force balance mechanism of multi-stage centrifugal pump and cancelled the balance disc device, which is the replacement product of D and DG type multi-stage centrifugal pump.
Because there is no balancing device, that is, no balance disc friction loss and no return loss of balanced water, the pump efficiency is 5~ 14% higher than that of the same type of multistage pump, and the shaft power of the pump is reduced in the case of the balance disc without friction, thus achieving an energy-saving effect, so the power consumption of the pump during operation is about 3% energy-saving compared with the same type of multistage pump. At the same time, it completely solves the various faults caused by the failure of the balance device, such as the wear of the balance disc and the balance ring or the bite of the rotor, and its design extends the service life of the pump. Trouble-free operation time is more than 3 times that of ordinary pumps, and user maintenance costs are greatly reduced, thus reducing the life cycle cost of pumps.
