High efficiency three-way closed impeller:
the application of efficient three-way closed impeller can achieve 6-8% higher efficiency and 6-8% lower energy consumption than the two-way impeller.
Overturning test:
After the impeller is processed, the overturning test is carried out at the rated speed of 110-120% to ensure the safety of the impeller in the field.
Integral steel base:
The main engine and gear box adopt integral base design. 100% pre-assembly shall be carried out in the factory and the pre-assembly position shall be recorded on the base by positioning pin.
-- Ensure the accuracy and cycle of on-site installation;
-- A startup debugging success;
-- Strong stiffness, offset the uneven settlement of concrete;
-- Concrete foundation construction is simple and the cost is low.
Balance plate design:
Through the balance plate, the pressure difference between inlet and outlet of turbine is used to balance the thrust of rotor, reduce the load of thrust bearing and improve the service life of thrust bearing.
Rotor material:
The impeller is made of imported high-strength stainless steel, which has been heat treated for many times during processing to ensure its strength and corrosion resistance. Stainless steel bushing is used to prevent corrosion effectively
Tilting tile bearing:
Tilting tile support bearing + Kingsbury thrust bearing is used to replace fixed tile. Tilting tile bearing blocks can swing freely with different speed, load and bearing temperature, and form multiple oil wedges around the journal. The stability is much higher than that of fixed tile bearings, and the whole machine runs stably with low vibration.
