Maintenance and Service for Decanter CentrifugesDecanter centrifuge
A decanter centrifuge is a machine that plays a central role in separation processes, such as dehydration and condensation, among various processes. Since the bowl and screw rotate with a slight clearance at high speed, they undergo many processes in maintenance and service, including proper disassembly, diagnosis, repair, and dynamic balance corrections.

Large Speed ReducersReducer
A speed reducer gradually reduces the high-speed rotation given to the input shaft via multiple gears that are different in the number of teeth and diameter, while it changes to a larger torque. This makes it necessary to have technology that can appropriately diagnose the conditions of the teeth through which force is transmitted and the conditions of the shafts and bearings that maintain rotation, whereby repairs, adjustments and assembly can be performed.
Main Maintenance and Service Details
Before & After Maintenance and Service
Before maintenance and service
Because of outdoor use, the casing was corroded and the gears were damaged.
After maintenance and service
A test run is performed after repairs, including fabrication of gears, and painting of the casing.

Roots Blowers Roots blower
A roots blower is a machine that conveys air with multiple blades called impellers, which are installed on parallel shafts, and rotated in opposite directions. The original performance can be restored by the proper setting of the clearances between the blades and between the blades and the case based on the measurement of each part.
Main Maintenance and Service Details
Before & After Maintenance and Service
Before maintenance and service
The input shaft had seized with the thickness reduced and the blades were not rotating.
After maintenance and service
The shaft was fabricated and replaced, and the clearance was adjusted and restored by machining.
