Centrifugal blower
Air suspension blower belongs to centrifugal blower. The single-stage high-speed centrifugal blower with air suspension bearing is a blower system with single-stage compression structure, whose centrifugal impeller is directly connected to the motor. Its frequency converter controls the speed to control the air volume.
It has modular design, core technologies (air bearing, motor, impeller, etc.) for integrated installation and optimization of compression section, frequency converter and programmable logic controller (PLC). They are important to ensure the stable and reliable operation.
Air bearing: While rotating, air flows on the surface of the shaft, generating pressure and forming an air film. As the speed of rotation increases, the shaft is suspended.
Advantage:
1. No contact or friction, high efficiency;
2. No lubricating requirement of oil;
Impeller:
High efficiency backward curved impeller;
Optimized assembly technology improves efficiency and adjustment range;
Five axis linkage NC machining ensures the accurate reflection of the design profile and excellent durability design.
Motor:
In high-speed rotation, patented self circulating cooling technology can ensure efficient operation;
The simple design can ensure excellent durability under extreme working conditions;
KSINO provides induction motors and permanent magnet synchronous motors。
Screw blower
Screw blower is a new product developed to meet the needs of energy conservation and environmental protection in the market by integrating years’ design and manufacturing experience. This series of screw blower has compact structure, unique appearance, high efficiency, low noise, reliable performance and long service life. It is very suitable for medium and small flow, high pressure applications. At present, it is widely used in metallurgy, machinery, chemical industry, geology, mining, power and other industrial fields of the ideal gas source equipment.
Main characteristics
1. The advanced rotor profile design can effectively reduce the fluid power loss and improve the efficiency of the main engine.
2. It has excellent internal compression characteristics and low power consumption. Compared with Roots blower, its energy-saving performance is up to 30%.
3. It adopts air cooling structure. Its single-stage pressure is 250kPa, without cooling water.
4. The oil-free design in the rotor cavity can ensure the air quality.
5. The air pulsation level is low. At high speed and high pressure, the fan can operate stably with low aerodynamic noise.
6. With the helical synchronous gear, keyless connection and reliable positioning, it ensures stable and safe operation within a large speed range.
7. The rotor is designed with large shaft diameter. The shaft has higher stiffness and bearing capacity.
8. The positioning end adopts four point angular contact ball. The combined configuration of bearing and cylindrical roller bearing ensures that the bearing has sufficient bearing capacity and stability under extreme working conditions, thus extending the service life of the bearing.
9. The casing adopts the structural design of intermediate connection, which makes the casing bear uniform force and improves the overall bearing capacity of the casing. The large stiffening rib design can enhance the casing stiffness, thus ensuring reliable operation under high pressure.
10. It adopts splash lubrication, with low power consumption for oil stirring, so as to ensure stable supply of lubricating oil for gears and bearings.
11. The unique gas seal setting has good sealing effect and long service life.
12. The end cover adopts streamlined radiator design, which is more conducive to heat dissipation of the gearbox.
