The use of Saudan Foss

Compared with the mechanical performance of fans of the same level, axial flow fans generally have lighter components, and the Saotanfus accessories are about 50% to 60% of centrifugal fans. Their flywheel torque is small, steel consumption is low, and infrastructure installation costs are saved. If calculated based on the structural component of the foundation, which is 3 to 4 times the flywheel torque of the fan (n=<1000r/mim), the foundation structure of centrifugal fans will consume about 4 times more data than that of dynamic blade adjustable axial flow fans and about 1.5 times more data than that of static blade adjustable axial flow fans.

From the perspective of mechanical performance of the fan, the dynamic blade adjustable axial flow fan is the best, followed by the SAO PV90R100 hydraulic pump accessory static blade adjustable axial flow fan, and then the centrifugal fan.

In terms of protection and maintenance of fan 1, although the structure of the Caesar air compressor's adjustable blade axial flow fan is messy, it has added a messy conditioning organization and hydraulic oil system, and the maintenance process requires high standards. Generally, it is required that the hydraulic oil and lubricating oil station of the dynamic regulating fan should use imported equipment with high reliability for the three blade Roots vacuum pump and conditioning equipment. Following the experience of operation and protection, the workload of wind turbine maintenance has not been large in recent years. For minor repairs, only the wear condition of the blades needs to be checked, while for major repairs, even if the blades are replaced, the fasteners at the blade root only need to be removed, making the repair more convenient.

The static blade adjustable axial flow fan requires replacement of blades during maintenance, and new blades need to be welded in a different direction on the meridian plane. This work cannot be carried out on site for the SAO PV90R075 hydraulic pump accessories and needs to be transported back to the manufacturing plant for replacement, which is also expensive.

During the maintenance of centrifugal fans, due to the heavy rotor of the hot sleeve structure, there will be significant difficulties in replacing the impeller in addition to regular blade welding.
